We developed a display device for motion picture. The display elements of each dot are composed of rotors of small stepping motors and are able to display one of four colors such as cyan, magenta, white and yellow. The stators, coils and magnetic circuits are arranged compactly in the cylindrical display element. The display elements are able to rotate and stop rapidly because they have small inertia and are well fitted to drive pulses. We made two display devices with the dot pitches of 6 mm and 20 mm, and they can display 30 frames and 15 frames of picturs per second, respectively.

Personal area network requires wireless communication system for exchanging information among wearable electronic devices. Intra-body communication that uses a human body as a transmission medium allows wireless communication without using airborne radio waves. Measurements of transmission characteristics of intra-body communication have shown that the optimum carrier frequency was 5MHz. Audio frequency signal was successfully transmitted through a human body using newly developed 10.7MHz FM transmitter and receiver modules, both having the size of 3cm by 3cm. The carrier frequency was selected to utilize commercial RF devices.

His Imperial Highness the Prince Takamatsu is a brother to the Present Emperor of Japan. The Prince has a collection of timepieces which is not very large, but each is very excellent as an antique. The Prince is not a positive collector and he seems to have inherited it as his ancestors' fortune. In his collection the writer found a stackfreed watch, the first discovery in Japan. Though the movement together with the dial and hand underwent reconstruction, the original watch seems to have been made in the 16th century or so. One more timepiece can be added to the existence of the oldest timepiece-the clock now kept at Kunozan Toshogu in Shizuoka City made in 1581 in Madrid and once owned by Iyeyasu Tokugawa.

A new method of measuring blood pressure has been proposed, which is based on the relationship between blood pressure and pulse wave velocity that passes artery wall. We paid attention to this method as this one was very advantageous to miniaturize the blood measuring instrument. We have developed a circuit to measure pulse wave velocity which can be transduced into blood pressure value. Furthemore we have brought Casio brand blood pressuer monitor watch to the market, of which circuit is miniaturized into one chip LSI. The constitution and the blood monitoring operation of this watch are described in this Paper.
