Title: Electronic watch
Inventor: SATOU KEINI
IPC: G04F5/06
Filed: 1977-11-09
Abstract: PURPOSE:To produce a porcelain capacitor of small size and capacity by using a porcelain dielectric which has a low specific dielectric constant and a high capacity changing rate for temperature. CONSTITUTION:As a starting material, BaTiO3, SrTiO3 and MgTiO3 are prepared to have the composition, as seen in Table. The resultant mixture is filtered, dried and molded, followed by sintering. The sample thus obtained is metered in a frequency of 10 KHz. The results have revealed that sample No.l has a high capacity changing rate and a considerably high specific dielectric constant. Smaples No. 2 and 3 have one second and third of the conventional specific dielectric constant but one second and third of the conventional specific dielectric constant but a substantially equal capacity changing rate so that they can be the most suitable for a temperature compensating capacitor of small tupe.

Title: Self-diagnostic result output control system
Inventor: TANAKA YASUHIRO
IPC: G06F11/22
Filed: 1994-06-17
Abstract: PURPOSE:To find a faulty position in the early stage by securely informing a device user that a self-diagnostic program detects an error by outputting the result on a printer if the error is detected. CONSTITUTION:As for an information processor which executes the self- diagnostic program consisting of hardware when a computer system is powered ON, a printer output control part 7 is actuated if the self-diagnostic program detects an error of hardware to output the error detection contents on the printer 9. Whether or not the error detection contents are outputted on the printer depends upon data stored in a register 5, and the data can optionally be set by the device user. Further, while the printer output control part 7 is actuated, the device user is unable to turn OFF the power source, and consequently the device user is securely informed of the error occurrence on paper. Thus, the error detection contents are outputted on the printer at the time of a self-diagnosis of the hardware when the computer is powered ON, thereby finding the faulty position in the early stage and taking a countermeasure quickly.
