Title: Power source circuit of public telephone
Inventor: HIKONE AKIO
IPC: H04M17/00
Filed: 1983-12-23
Abstract: PURPOSE:To eliminate restriction of the length of lines by using a constant voltage diode using sufficiently high Zener voltage when driving a magnet for receiving coins, using a sub-constant voltage diode in other conditions thereby charging condensers alternately. CONSTITUTION:The sub-constant voltage diode ZD2 is connected with the constant voltage diode ZD1 in the same direction and in parallel, and Zener voltage of the ZD2 is set lower than Zener voltage of the ZD1, for instance 4V. Accordingly, the constant voltage diode ZD1 goes to off state. At the same time, condensers C2-C6 are charged by Zener voltage of the sub-constant voltage diode ZD2, thereby each power source is supplied. As considerable electric power is required for driving a magnet CM, the sub-constant voltage diode ZD2 is cut off from a DC loop, and loop current is supplied to the constant voltage diode ZD1. Thus, condensers C2-C6 are charged quickly in a short time by the sufficiently high Zener voltage to prevent the occurrence of impediments for receiving coins.

Title: Method and device for recording and reproducing optical information
Inventor: SHINBAYASHI TOSHIYA
IPC: G11B7/00
Filed: 1986-10-15
Abstract: PURPOSE:To prevent the recording film from being changed in quality and damaged even at a standby state for a long time by moving a laser beam between at least two adjacent tracks or over of a disk recording medium during the standby state. CONSTITUTION:One output pulse 7s is outputted very at time an index provided to an optical disk 1 passes on a photocoupler 7. An output 8s being the frequency-division of the pulse at a 1/f frequency division counter 8 is an output pulse per one cycle. A counter 9 frequency-divides an input signal 8s by 1/3, a Q output and the inverse of O output of a D-FF circuit 90 are logic 1 alternately at every 3-revolution of the optical disk 1 and inputted to AND gates 91, 92. A control signal 90c being logic 1 at the standby state is connected to the gates 91, 92, resulting that signals 91s, 92s are obtained and in using them as bipolar track jump signal, the laser beam is moved among four adjacent tracks during the standby period. Since the single track is not continuously radiated even with a long standby period, the temperature raise of the recording film is less and the possibility of the change in the quality and damage of the medium is precluded.

Title: Lubricating mechanism for oil seal of ignition distributor
Inventor: MIYAGAWA MASANORI
IPC: F02P7/10
Filed: 1986-10-14
Abstract: PURPOSE:To prevent an oil seal from being worm away as well as to prevent oil from penetrating into a distributor, by making the feed of oil to the oil seal so as to be performed by utilizing a pressure differential to be produced between an oil suction port and an oil outflow port at the time of rotation of a rotary member. CONSTITUTION:When an engine starts and a cam shaft 200 is rotated, distributor drive shaft 110 is rotated via a connecting member 120. With this rotation, negative pressure is generated in a clearance between this connecting member 120 and an end face of a support part A, but this negative pressure differs in a broad part 133 and a narrow part 134 of the clearance. In consequence, there is produced a pressure differential between an oil suction port 171 and an oil outflow port 182, and if the pressure differential grows larger, air in a cam cover 210 is inhaled into a space 137, and the air inside the space 137 is discharged into the cam cover 210 again. At this time, oil or the like scattered inside the cover 210 is sucked in by a flow of air whereby it is fed to the space 137 and lubricated to an oil seal 160.

Title: Formation of etching pattern
Inventor: SEKIGUCHI ATSUSHI
IPC: H01L21/304
Filed: 1992-09-11
Abstract: PURPOSE:To achieve high dimensional controllability by ending the etching operation at a point of time obtained by multiplying a predetermined overetching coefficient. CONSTITUTION:Detection signal from a phototransistor 10 is fed to an A/D converter 15 where it is converted into a digital signal and subjected to waveform analysis by means of a computor 12. A rinse liquid supply mechanism 5 or a motor drive circuit 13 is then controlled depending on waveform analysis results. Upon detecting a break-through point, the computor 12 measures a time interval CRT after start of etching before detection of the break-through point and then multiplies the time interval CRT by an overetching coefficient, predetermined experimentally, thus calculating a total etching time. Etching operation is stopped upon elapse of the total etching time thus calculated. This method allows etching at a constant line width regardless of variation of etching conditions.
