ジャーナル フリーThis paper describes the channel pulse generator for the transistorized high speed time analyzer TATT-1. Presented are details of the 10 Mc pulsed oscillator, non-delay frequency divider and high resolution monostable multivibrators, storage counter type frequency divider and high speed pulse shapers. The non-delay frequency divider which can provide out put pulses with a little phase delay consists of a diode AND gate and high resolution monostable multi HRMM's, one of which is able to attain the duty ratio of 95% with an output pulse width of 1μs. Also given is a design procedure of the storage counter type (STC type) frequency divider. Stable operations are expected with the STC type frequency divider designed through this procedure for intermittent in put pulses in a wide temperature range. The high speed pulse shaper contains a tuned differentiator for compensation of stray capacities which also secures a stable high speed operation for intermittent inputs. Although all these circuits have been originally designed for TATT-1, they would be applied to various high speed pulse systems.抄録全体を表示PDF形式でダウンロード (1754K) -

ジャーナル フリーGiven in this paper is a design method of parameter adjusting systems. Parameter optimization is essential for the adaptive systems and also is applicable to the identification problems. The identifying system considered in this paper employs the method of the steepest descent. Parameters are adjusted at the speed proportional to the gradient of the penalty function. Although this method is essentially equivalent in value to the parameter perturbation method, it does not require the perturbation signals but utilizes the partial derivatives concerning the parameters of the model in the system. Thus, a simpler system can be obtained even if there are many parameters to be adjusted. In this paper, a construction method of the parameter adjusting identification system is developed and then an investigation is carried out about the dynamic characteristics of the parameter adjusting processes. Approach to the dynamics is conducted through differential equations. The Hill's differential equations play an important role in this investigation. Noteworthy results are as follows: The parameter adjustment can be done as rapidly as the order of e-t/2T, where T is the time constant of the averaging element in the parameter adjusting loop. The time constant T can be taken as small as a quarter of the period of the lowest frequency component passing through the system to be measured. A simple design procedure is also given to assure this extremely rapid parameter adjustment.抄録全体を表示PDF形式でダウンロード (885K) -

ジャーナル フリーThis paper describes the characteristics of a pulse motor with a new viscous damper which prevents the pulse motor from hunting. The damper is composed of two parts placed concentrically, one is a rotatable and has a soft iron armature, which is supported on a shaft by ball bearings and has a plurality of spaced poles, and a damper case fixed on the shaft having a suitable gap around the armature which is filled up with silicone oil, and the other is of stationary field structure with an excite coil and as many poles as the armatures. Using the damper, the writer has obtained a pulse motor which is usable at +5° to +85°C temperature, 0 to 500 pps frequency and maximum 700g-cm pull out torque without hunting.抄録全体を表示PDF形式でダウンロード (827K) -

ジャーナル フリーThis paper describes a system to automatically measure and track the frequency with constant phase lag and its gain, considering the process transfer characteristics in the domain of frequency. This system with two closed loops, each for frequency and gain, consists of analog computing components and simple relay switching devices. An analytical study is made on the static behaviours of this automatic tracking system and the way to reduce static errors is discussed. The response speed of this tracking loop has a certain limit because output fluctuation is increased if speeded up. Therefore, it is considered to design such a system that is fastest in the speed of tracking loop response and yet has a given output variance in a steady state.抄録全体を表示PDF形式でダウンロード (1627K) -

ジャーナル フリーDescribed in this paper is a method for precision SWR measurement in rectangular waveguides. This method uses a magic T as a measuring circuit instead of a slotted line and gets both the maximum and minimum values of a standing weve by tuning a sliding short plunger connected to one of the main arm of the magic T. The principle and method for adjustment of the measuring circuit for precision measurement are given. Errors due to such reasons as non-ideal property of a magic T, loss of a sliding short and incomplete adjustment of a measuring circuit are analyzed, and the error is proved to be below 0.1% for VSWR=1, 50 by using a X band magic T and a sliding short on the free market.抄録全体を表示PDF形式でダウンロード (3309K) -
