Title: Clock extraction circuit
Inventor: SOMA MASAHIRO
IPC: H03K5/00
Filed: 1988-03-01
Abstract: PURPOSE:To attain clock extraction with simple circuit constitution by extracting a clock frequency component by employing a low-pass filter and a rectifier circuit only. CONSTITUTION:With a signal 11 given to a low-pass filter 1, an undesired frequency component is cut off and a signal 12 is obtained while the DC component is cut off by a capacitor. A signal 13 whose frequency is multiplied is obtained by passing the signal 12 through the rectifier circuit 3. Moreover, the clock is extracted by a resonance circuit 4 to obtain a signal 14. The signal 14 is formed into a complete clock signal 15 by a comparator 5. Thus, the clock is extracted with simple constitution.

Title: Digital indication type speedometer for vehicle
Inventor: SHINOHARA TOSHIO
IPC: G01P3/46
Filed: 1980-04-14
Abstract: PURPOSE:To indicate 0 km/h forcedly without any delay in response even at the time of a sudden stop by memorizing the content of counting sequentially and comparing the vehicle speed at this time with the vehicle speed at the previous time and a reference vehicle speed in the speedometer counting a vehicle speed pulse every fixed gate time. CONSTITUTION:The vehicle speed pulse from a detecting part 10 passes a gate 14 only for a prescribed time and is counted by a counter 16. In accordance with the output from a reset pulse generator 23, the content of counting in the counter 16 is transferred sequentially from the counter 16 to a register 24, thence from the register 24 to a vehicle speed register 26 and further from the vehicle speed register 26 to a similar register 28. And, the content of counting read out by a control circuit 32 is compared with the reference speed N0 and a reference deceleration N4 in a memory circuit 34 at a comparison circuit 38. On condition that such total conditions as N1 (counted value of this time) <= N0, N2 (counted value of previous time) -N1>=N4 and N3 (counted value of two times before)-N2>=N4 are effected (at the time of a sudden stop), an AND circuit 46 gives an output and an indication register 18 is reset forcedly by a reset circuit 48, and therefore, an indication part 22 indicates the vehicle speed of 0.

IPC: G08B17/12
Filed: 1987-03-06
Abstract: PURPOSE:To obtain a fire detector which does not malfunction by inhibiting a switching circuit which operates with a specific output from an amplifier for low-frequency amplification from operating when an amplifier which performs high-frequency amplification is generates a specific output. CONSTITUTION:When a pyroelectric element 21 generates an AC output of about 8Hz low frequency owing to deterioration, the output of a smoothing circuit 51 becomes larger then the output of a smoothing circuit 52 as well as in case of a fire, a comparator 6 generates a high-level output, and an integration circuit 71 begins to perform its integrating operation.

Consequently, the transistor Tr of the integration circuit 71 with a long integration time is turned on, the integration circuit 71 is inhibited from operating, and the switching circuit 81 does not operate, so that no wrong fire signal is sent out to a receiver.

Title: Threshold voltage generator of mos transistor
Inventor: ANTOWAN PEBURAN
IPC: H03K5/08
Filed: 1989-03-03
Abstract: PURPOSE: To supply always suitable threshold voltage to a MOS transistor(TR) by providing the threshold voltage generating circuit with a 2nd comparator, and 2nd and 3rd inverters to execute operation capable of allowing the variation of parameters generated due to temperature variation or the like. CONSTITUTION: When the threshold voltage VT of a MOS TR 1 in an inverter 7 is boosted from an equilibrium state (the threshold voltage of a TR 3 in the same IC is simultaneously boosted) due to temperature variation e.g. a current flowing into the TR 71 is reduced. The bias voltage of a terminal 8 is boosted due to the reduction of the current and node voltage VX between TRs 51, 52 in a comparator 5 is reduced. Thereby the output voltage of the comparator 5 is reduced and the input voltage VP of the TR 71 is boosted. When the voltage VP is boosted, the bias voltage of the terminal 8 is reduced. Thus a change in the bias voltage acts so as to offset the boost of the voltage VT. When the voltage VT is reduce also, similar offset action is driven. Consequently the output voltage, i.e., bias voltage, of the inverter 7 holds the threshold voltage of the TR 3 always at an optimum value.
