Title: Sawtooth wave generator
Inventor: HATACHI SHINJI
IPC: H03K4/56
Filed: 1980-10-23
Abstract: PURPOSE:To obtain a sawtooth wave generator where the linearity is not degraded even if an external signal is superposed, by constituting amplifiers operating as a Miller integrator in two stages. CONSTITUTION:When a DC power is applied to a power supply terminal 11 and a horizontal driving pulse (a) is applied to a terminal 10, amplifiers 14 and 16 constitute a Miller integrator together with a capacitor 2 and a resistance 3, and sawtooth wave voltages (b) and (c) are generated in an output terminal 9. Next, when an external signal which is a part of a vertical deflecting voltage (d) is applied to a terminal 7, an output (e) is obtained in the output terminal 9. Consequently, since a sawtooth wave voltage for horizontal deflection which is a main signal is generated by the Miller integration due to amplifiers 14 and 16, the linearity is not degraded, and a saw tooth wave voltage of a good linearity is obtained.

Title: Dynamic type semiconductor storage device
Inventor: TAKEMAE YOSHIHIRO
IPC: G11C11/406
Filed: 1985-07-09
Abstract: PURPOSE:To practically remove the prevention of a memory access by forcibly carrying out the refresh while preventing immediately the memory access if not colliding against the memory access and finally of a period if colliding until the last of the period. CONSTITUTION:A peripheral circuit 20 for refresh generates a clock CLKR for a refresh in a fixed cycle and inputs to a block selection control circuit 40. A block selecting circuit 40 does not supply a refresh standby signal such as a refresh address increment non performance signal NINC to the peripheral circuit 20. A decoder 41 for refresh block selecting signal continues to turn on one of selecting signals PRBS0-PRBS3 of the block to be refreshed. A refresh block selecting signal activating circuit 47' turns on one of the outputs PBS0-PBS3 corresponding to one of the inputs PRBS0-PRBS3 which is turned on while a refresh activating signal RAS from a refresh/access selecting circuit 46' is turned on.

Title: Induction heat cooking device
Inventor: OMORI HIDEKI
IPC: H05B6/06
Filed: 1990-06-07
Abstract: PURPOSE:To prevent production of interferrence sound when a plurality of induction heat cooking devices are used close to each other by setting an action frequency constant, and changing the energization time for two switching elements so as to change a heating power. CONSTITUTION:A changeable duty oscillation circuit 19 changes the ratio of an energization time for a switching element Qa to an energization time for a switching element Qb corresponding to an instruction from a duty setting circuit 20. The oscillation frequency of the changeable duty oscillation circuit 19 is set to be close to a resonance frequency of a load circuit 15. In this constitution, a heating power can be changed without changing an action frequency corresponding to the instruction from the duty setting circuit 20. Interferrence sound to occur when a plural induction heat cooking devices are used close to each other can thus be prevented, thereby an induction heat cooking device having a good environmental property can be obtained.

IPC: G06F9/06
Filed: 1990-06-11
Abstract: PURPOSE:To use an IC card as a substantially complete good product and to improve the yield of the product even if a defect occurs in a program in a mask ROM by storing a processing shifting routine program for EEPROM into mask ROM. CONSTITUTION:The processing shifting routing program 15 is added and stored in mask ROM 3.

Title: Infrared crime prevention detector
Inventor: KONDO MIKIO
IPC: G08B13/18
Filed: 1987-06-16
Abstract: PURPOSE:To prevent the surface of a detector cover from being frosted by arranging a recessed part or a projected part on a part through which projected/ received beams to/from the detector cover are passed so that downward face is made approximately horizontal. CONSTITUTION:Vapor evaporated from the ground surface at night in the winder season is raised along the front of the detector cover 6 and flows on the front because air is stagnated on a recessed groove part 7. Thereby, the vertical wall face on the lower side of a face 8 directed to the lower part of the recessed groove 7 is not frosted, so that the quantity of infrared rays necessary for driving a detecting function can be received or projected to/from the unfrosted part and misinformation or disabled alarm can be removed. When a step part 9 extended in a horizontal direction is formed on a part of a light projection part 6 of the cover 5, similar effect can be expected and the adhesion of frost can be prevented.

Next, the deviation signals are multiplied N times by a Nth power circuit 14 and inputted to mixing circuits 15 and 16 in a subsequent stage to be mixed. Then, the mixed signals are passed through low-pass filters 17 and 18 respectively and an output signal of a phase A and an output signal of a phase B are obtained from output terminals 19 and 20. These output signals of the phase A and the phase B have periods of 1/N of the original signals.

Title: Electronic parts having temperature regulating function
Inventor: WATANABE GENICHI
IPC: G12B7/00
Filed: 1986-06-25
Abstract: PURPOSE:To simply and accurately make temperature regulation possible by forming a heating unit for temperature regulation on a substrate and in contact with the body of a part in a structure in which the body of the part is attached to a fitting substrate. CONSTITUTION:The electronic part 1 is made by printing a heat generating resistor 3 on a ceramic substrate 2 and mounting the body 4 of the part on its upper face to cover the resistor 3. As the body 4 is mounted directly on the upper face of the resistor 3, when current is applied to the resistor 3, the back of the body 4 is heated directly, and temperature of the body 4 is regulated directly. By making temperature regulation utilizing self feedback characteristic using the resistor 3 also as a temperature detector, regulation of temperature of the body 4 itself becomes possible. Accordingly, response to heat becomes quick. Especially, as abrupt change of outside temperature can be followed satisfactorily, maintenance and accuracy of temperature stability of the electronic part is improved. Further, manufacturing cost becomes low.
