Title: Electromagnetic flowmeter
Inventor: KOBAYASHI TAMOTSU
IPC: G01F1/60
Filed: 1987-04-13
Abstract: PURPOSE:To obtain a flowmeter substantially stable in a zero point and strong against low noise, by altering the ratio of low and high frequency exciting outputs corresponding to the magnitude of the flow noise. CONSTITUTION:A timing signal S1 repeats ON/OFF action and the application of reference voltage E1 to the non-reversal input terminal of an amplifier Q1 is controlled while an exciting current If flows by timing signals S2, S3. Further, the signal voltage at a coupling point 15 is sampled by timing signals S7, S8 and voltage VL is outputted to a coupling circuit 19. Further, the signal voltage at the coupling point 15 is sampled by timing signals S9, S10 to be outputted to the circuit 19 as voltage VH. When there is flow noise, the subtractor Q7 of a noise discrimination circuit 21 performs the subtraction of the outputs of low-band filters 16, 17 to output noise voltage. This voltage is inputted to a voltage/pulse duty converter V/D as the DC voltage corresponding to the change of noise to be applied to switches SW11, SW12. When there is no flow noise, the voltage VL on a low frequency side stable in a zero point is outputted to a terminal 20.

IPC: C08L23/10
Filed: 1994-04-27
Abstract: PURPOSE:To obtain a resin molding capable of improving the dimensional stability and strength, preventing the blister from occurring and further keeping its excellent water resistant property. CONSTITUTION:The side molding 1 is equipped with the major part of a molding body 2 comprising a polypropylene as a major component and a filmy layer 3, formed on the surface of the molding and constituted of an acrylic urethane coating.

Abstract: PURPOSE: To set up widely the dynamic range of an optical receiving system by a method wherein the bias voltage of an APD is kept to low during two different components of an output signal of an amplifier or an input signal of a discriminator satisfy desired charactersitics.  
     CONSTITUTION: An input signal 2 having the frequency component shown with a solid line in the figure (c) is designated as "1", and the signal shown with a one dot line is designated as "0". When the input 2 is "1", an input to a register 14 from an A/D converter 13 is sent to a D/A converter 15 coinciding with the clock signal from an oscillator 17 to generate a bias voltage in a high tension generator 16 necessary for an avalanche photo diode APD. In this constitution, when the input 2 is "1", the circuit 16 send out the bias voltage to the APD to keep the peak value of the input 2 to be constant. When the input 2 is "0", the registor 14 is kept in the state when it received the input from the converter 13 just before the input 2 change to "0". therefore the output of the circuit 16 is fixed to the value before the internal capacity of the APD change suddenly.
