Title: Pulse counting device
Inventor: YANAIDA YOICHI
IPC: G01P3/489
Filed: 1987-01-31
Abstract: PURPOSE:To perform a natural display having no regularity by providing an adder, a comparator, a display circuit, an addition value deciding circuit, etc. CONSTITUTION:The adder 8 sums counted values of all registers and outputs the latest calculated sum to the comparing circuit 9. This comparator 9 compares the latest sum with a value which is equal to a value outputted from the comparator 9 to a display circuit in a previous division time and stored in a register 11 for storage. At this time, when the difference between the value outputted from the comparator 9 to the register 11 and the latest sum is <='3', the latest sum is outputted to the circuit 10 as it is. When the difference is >='4', the comparator 9 corrects or does not correct the latest sum from the adder according to the output signal of the addition value decision circuit 12 to the comparator 9. Thus, a natural display having no regularity is executed.

Title: Micro-flow sensor
Inventor: UMEMOTO HIDETOSHI
IPC: G01P5/12
Filed: 1991-02-15
Abstract: PURPOSE:To obtain a micro-flow sensor which is less in power consumption, high in sensitivity, and smoothly driven with a pulse by forming at least either an exothermic resistor or temperature measuring resistor of a laminated resistor composed of a plurality of layers and increasing the resistance value of the laminated resistor. CONSTITUTION:A temperature measuring resistor is composed of a lower and upper layers 11 and 12 and an exothermic resistor is composed of a lower and upper layers 21 and 22. The lower layer resistors 11 and 21 are respectively connected with the upper layer resistors 12 and 22 through coupling sections 8 and the resistors 11 and 21 are insulated from the resistors 12 and 22 with an intermediate dielectric layer 9. As a result, the power consumption of the exothermic resistor can be reduced by increasing the resistance value of the exothermic resistor and the magnitude of a bridge output signal can be made larger by increasing the resistance of the temperature measuring resistor. In addition, a decline in the responding speed at the time of driving the micro-flow sensor with a pulse can be prevented by reducing the interline mutual inductance when the strip resistors of one layer are put on the top, bottom, and middle of the strip resistors of the adjacent layer.

Abstract: PURPOSE:To improve the frequency characteristic when a signal is attenuated by connecting a gain control AC signal source and a DC signal source in parallel between the emitters of TRs of differential connection and common so as to constitute a gain control circuit. CONSTITUTION:The gain control AC signal source 13 and the DC signal source 14 are connected in parallel between the emitters of the TRs 11, 12 and common respectively and an input signal inputted to bases 17, 18 of the TRs 11, 12 is controlled in response to the value of the signal sources 13, 14 to output a gain-controlled signal from an output terminal 19. A DC current component of the signal source 14 is included in the collector current of the TRs 11, 12 by connecting the DC signal source 14 but no effect is given at all to the AC output voltage obtained at the output terminal 19. Thus, the DC current component is added to increase the operating current of the TRs thereby improving the frequency characteristic of the TRs.
