Nowadays, digital quartz watches have a tendency to be multi- functionized. This report is concerned with the develop-ment of the quartz watch, "Memory Bank Calendar" Caliber M354, provided with monthly calendar display function. This digital quartz watch has been realized and put on the market by the development of specially designed integrated circuit and two-layer liquid crystal panel. The two-layer L C. panel has new advantageous functions such as monthly calendar and memory bank ones which enables to store any desired date.

本研究は、最重度知的障害を伴う自閉症成人女性に対して、1時間単位の時計の読みと時系列の順序を指導した事例研究である。対象者は、28年間施設を入所利用し、)し2年から重症心身障害児施設を入所利用する41歳の最重度知的障害を伴う自閉症のある女性である。モデル提示、弁別訓練、プロンプトを用いた約30分の指導セッションを45試行、フォローアップを5試行実施した。介入の結果、アセスメントでは7以上の数字を読むことができなかった対象者が、段階的な指導を行うことにより1時間単位の時計の読みと時系列の順序を獲得することができた。3カ月半後のフォローアップでは時計の読みスキルの維持と他の時計への般化も確認された。本研究の結果から、段階的な行動的支援方法を用いることにより、最重度知的障害を伴う自閉症成人に対して、日常生活に応用可能な新たなスキルを形成できることが示された。

This research proposes methods for understanding the immunity performance of switching power supplies with an actual load against electromagnetic compatibility (EMC: EMI + EMS(immunity)) of switching power supplies. In the conventional immunity test of switching power supplies (IEC61000-4-4), since the test with a resistive load, there is no effect on the load, even if noise applied from the AC line is transmitted to the load side. However, since the load is usually an actual load, such as an electronic device (PC and other), malfunctions may occur depending on the magnitude of the noise transmitted to the load side. Therefore, in this study, the output voltage spectrum during the immunity test was measured, and the immunity was evaluated considering the effect on the actual load.

これからの放送サービスは従来のテレビ受信機だけにとどまらず,テレビ受信機の周りに存在する様々な外部端末に拡大していくことが検討されている.外部端末の進化は早く,新たな放送サービスをこれら外部端末に提供していくには,その進化に追随可能な仕組みが必要である.そこでテレビ受信機と外部端末がLAN接続されている環境を前提に,放送局と外部端末とを放送波に載せたIPパケットで接続して,外部端末の進化やサービスの変更に柔軟に対応する放送通信連携システムを試作し,MBSのホワイトスペース特区「茶屋町TV」で実証実験を行った.

  We have developed a thin digital running watch. Set 4 points to improve basic performance. (1) Wearability (2) Easy to see (3) Long-term use (4) Easy to use. The product was realized by developing elements such as the size and thinness of the movement, display, button layout, and power supply. Then, through hearings with runners, we worked to improve the usability of the product.

In total hip arthroplasty (THA), the rolling motion of the patient in both the forward and backward directions can easily occur particulary using the posterolateral approach, making it difficult to place the acetabular cup in a suitable angle. We devised a three-dimensional goniometer which consists of three goniometers to assess multi-directional pelvic motion during THA. The purpose of this study is to assess the pelvic motion during THA with posterolateral approach using our device. This prospective study involved 26 THAs in 25 cases. Each patient was placed in a lateral decubitus position on the operating table. A Steinmann-pin was inserted into the illium on the operated side. Our device was attached to the Steinmann-pin. Using this device, we measured the tilt angle of the pelvis in the horizontal plane, frontal plane, and sagittal plane before dislocation and at the time of cup placement. The changes of the tilting angle of each plane were analyzed in the three-dimensional directions. In the horizontal plane, the pelvis tilted forward, averaging 14.35 degrees. In the frontal plane, the pelvis tilted toward the caudal, averaging 0.08 degrees. In the sagittal plane, the pelvis tilted backward averaging 3.96 degrees. Pelvic motion primarily occurred when the Hohman-retractor was used for acetabular exposure.

Looking ahead into the coming main stream of buzzer for watch, we directed our attention toward the case back direct drive type piezoelectric buzzer whose volume is not turned down when the watch is worn on the wrist. We succeeded in developing and putting it to practical use. The principal merits of this buzzer are as follows. 1. Design and structure of watch are not restricted. 2. It is possible to make watch thin. 3. High pressure resistant waterproof watch can be realized without any structural speciality. 4. The cost is greatly reduced.
