Patent JP-H06307904-A (JP)
Title: Electromagnetic flowmeter
Inventor: OTA HIRONOBU
IPC: G01F1/60
Filed: 1993-04-23
Abstract: PURPOSE:To allow the elimination of the influence of differentiation noise by equalizing the rising and falling waveforms of exciting current thereby equalizing the differentiation noise occurring before and after a non-exciting interval. CONSTITUTION:A control signal VC3 outputted from a CPU causes a reference voltage generator STD to output a reference voltage Es having identical rising and falling waveforms. A deviation amplifier Q1 controls a transistor Q2 to match the voltage across the amplifier Q1 thus matching the waveforms of the exciting current Itau2 and the voltage Es. Since a magnetic field B also has identical rising and falling waveforms, differentiation noise having identical waveform is generated. Upon application of the magnetic field B, a switch 17 samples the detection signal under the control of a control signal VC4 from the CPU and stores the detection signal in a RAM 2. When a microcomputor 21 averages the data during non-exciting interval, extracts only the differentiation noise and subtracts the differentiation noise from the sampling data during the non-exciting interval, the influence of the differentiation noise can be eliminated even for high exciting frequency.

Title: Solid-state image sensor
IPC: H01L27/146
Filed: 1992-03-24
Abstract: PURPOSE:To lessen a dark current induced on the surface of a photodetective element due to positive charge inside a thin insulating film by a method wherein a potential lower than that of a hole accumulation layer is given to a light shading film. CONSTITUTION:Semiconductor layers 3a and 4a have the same impurity concentration profile with an N-type photodetector 3 and a P<+>-type hole accumulation layer 4 respectively, and a resistance monitor is composed of the semiconductor layers 3a and 4a. Vr is set to one volt, Is and Vs are measured, and a sensor resistance Rs is obtained by a formula, where W and L denote the width and the length of a resistor. The sensor resistance Rs is determined by the channel width W of a P<+>-type semiconductor layer 8a. When holes are depleted in the layer 4, a dark current increases. Therefore, a potential lower than that of the hole accumulation layer 4 is given to a light shading film 9 to prevent the layer 4 from being depressed, whereby the sensor resistance Rs hardly changes even if the PSG film 8 is formed thin. Therefore, a solid-state image sensing device can be reduced in dark current even if the PSG film 8 is set thin.
