Title: Electronic time piece
Inventor: MURAKAMI AKIKATSU
IPC: G04C10/04
Filed: 1998-10-12
Abstract: PROBLEM TO BE SOLVED: To judge battery voltage only by distinguishing paced pulse period by providing a voltage detection circuit and with the output, switching at least two progression pulses. SOLUTION: When a battery voltage detection circuit 11 judges that the secondary battery voltage is higher than a preset voltage, a paced pulse waveform rectifier circuit 4 rectifies the paced pulses of 1 second period by the command of the paced pulse switching circuit 12 and outputs it to a motor 6 through a motor driving circuit 5. If currents of 1 second period are sent to the motor 6, a pace meter can detect the motor magnetic field and measure the pace. Conversely, when the preset voltage is higher, paced pulses of 5 second period are rectified and output to the motor 6. In both cases, the paced pulse period can be confirmed with indication such as LED.

Title: Catv system and relay amplifier
Inventor: AOYAMA SHIGEYUKI
IPC: H04B3/46
Filed: 1988-11-16
Abstract: PURPOSE:To allow the system at the upperstream side of power feeding to continue communication normally by interrupting a power feeding line after the elapse of interruption delay time set shorter as the feeding voltage much drops and stopping the interruption of the power feeding line when the feeding voltage is recovered before the elapse of the interruption delay time on the other hand. CONSTITUTION:Voltage detection circuits 30a-30g detecting the voltage of the power feeding line are connected between earth and power feeding lines 13a-13g respectively. The voltage of the power feeding lines 13a-13g arranged in a relay amplifier is detected and when the feeding voltage is dropped, the relevant power feeding line is interrupted after the elapse of the interrupt delay time set shorter ad the feeding voltage much drops from the point of time when the feeding voltage is lowered. On the other hand, when the feeding voltage is recovered before the elapse of the interruption delay time, the interruption of the power feeding line is stopped. Thus, the transmission line of the power feeding downstream from the short-circuit point is disconnected and the transmission at the upperstream of the short-circuit point is made alive, thereby making the range of fault narrow.

Abstract: PURPOSE:To obtain a desirable shape pattern without inducing any abnormality in a patterning due to the succeeding etching process, etc., by making the width of a side wall near a region where a node polysilicon in a stack-type dynamic memory cell contacts an Si substrate to be small by an anisotropic etching.

For example, opening shape is determined by a photo resist 1 for opening the contact region between the node polysilicon and an Si substrate 8 and then dry etching is performed but the film thickness of an oxide film 9 is etched to approximately 1000Angstrom  after dry etching when performing the RIE etching(reactive ion etching). After that, the contact region is opened, thus preventing weak points from being produced easily.
