Title: Counter circuit
Inventor: ONO KAZUHIKO
IPC: H03K25/00
Filed: 1981-03-05
Abstract: PURPOSE:To decrease the number of elements used for a counter circuit by charging a capacitor every time an input pulse is applied, and then discharging the capacitor when a charging voltage exceeds the threshold level of a waveform shaping circuit. CONSTITUTION:Transistors (TR) E1 and E2 are connected in series between power terminals, and a capacitor C1 is connected between a connection point between those two TRs and a reference potential terminal, constituting a charging and discharging circuit. An input pulse is applied to the gate of the TRE1, whose output is applied to a waveform shaping circuit; and the output of the waveform shaping circuit is applied to the gate of the TRE2. Every time the input pulse is applied, the TRE1 turns on and the charging voltage of the capacitor C1 rises stepwise. When the output voltage of the charging and discharging  circuit exceeds the threshold level of the waveform shaping circuit, the TRE2  turns on by its output to discharge the charge of the capacitor C1.

IPC: C08G64/30
Filed: 1989-02-10
Abstract: PURPOSE:To obtain a high-MW chloride ion-free polycarbonate without using toxic phosgene by polycondensing a bisphenol with a specified carbonate by melting in the presence of an electron-donating amine compound catalyst. CONSTITUTION:A bisphenol is polycondensed with bis(2,4,6trichlorophenyl) carbonate, bis(2,4-dichlorophenyl) carbonate or bis(2-cyanophenyl) carbonate by melting in the presence of a catalyst selected from electron-donating amine compounds to obtain the purpose polycarbonate. Examples of the bisphenol used include compounds of formulas I-IV (wherein R1, R2, R3 and R4 are each H, a 1-8C linear or branched alkyl or a phenyl; X is a halogen atom; and n is 0-4). The temperature of the polycondensation reaction is desirably 130-250 deg.C. When this temperature is below 130 deg.C, the reaction rate is low, and when it is above 250 deg.C, side reactions are apt to occur.

Title: Reproduction of relief pattern
Inventor: KUWABARA YUKO
IPC: G03H1/20
Filed: 1993-02-22
Abstract: PURPOSE:To easily and safely reproduce defectless relief patterns by interposing an uncured resin between an original plate and a substrate for reproduction and irradiating this resin with UV rays or electron beams to properly cure the resin, then peeling this original plate and the substrate for reproduction and dipping the remaining resist into a peeling liquid to remove the resist. CONSTITUTION:A chromium mask 4 having patterns 5 formed on it and a dry plate 3 formed by laminating the positive type resist on a glass substrate 1 are brought into tight contact with each other opposite to each other and are then irradiated with the UV light 6 and developed to produce the original plate having the relief patterns 7 formed on it. The substrate 8 for reproduction is then pressed to this original plate so as to face the original plate by interposing the uncured resin 9 therebetween and thereafter, the resin 9 is cured by irradiation with the UV light or electron beams. This irradiation is regulated to the extent that the resist 7 is made easily soluble in a solvent and is destroyed at the time of peeling. Consequently, the cured relief patterns 10 are not destroyed at all and rather the destroyed resist 11 remains at the edges, etc., of the pattern when the substrate 8 reproduced from the original plate is peeled. The remaining resist is easily removable by the peeling liquid.

Title: Semiconductor device
Inventor: SHIMADA NAOKI
IPC: H05K3/34
Filed: 1988-02-17
Abstract: PURPOSE:To improve the sucking-up properties of solder to a lead cutting section at the time of substrate mounting by forming grooves or irregularities to a lead-cutting section side-face section soldered to a substrate wiring at the time of substrate mounting.

Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous input and to improve operability for respective operators by varying depression time (depression recognition time) being a reference for recognizing whether a touch panel is depressed or not and setting it. SOLUTION: When an operator depresses a key, a touch panel 18 is turned on and counting by a depression time timer is started. When the touch panel 18 is turned off, counting by the timer is stopped. When the count value of the timer is smaller than the depression recognition time of the operator, which is set in RAM 13, it is judged that the key depression of this time is a depression error, the content of key depression is ignored and '1' is added to data on the number of depression error times in RAM 13. When the number of depression error times reaches the reference number of depression error times, a warning message is displayed on the display screen of LCD 17 and the operator is urged to set again depression recognition time.
