Patent JP-H0259618-A (JP)
Title: Liquid level sensor
Inventor: HIRAYAMA YOSHIO
IPC: G01F23/22
Filed: 1988-08-24
Abstract: PURPOSE:To obtain the title liquid level sensor having high sensitivity and high accuracy by providing a heating element for generating a fixed heating value and a temperature sensor for detecting a temperature of this heating element and discriminating whether the heating element is in a liquid or gas from an output variation of the temperature sensor. CONSTITUTION:By adjusting a voltage of a DC power source 15, a fixed current is supplied to a heater 8. The heaters 8 of detecting elements LS1 - LSn are all the same, and since an equal current flows, an equal heating value is generat ed. Temperature differences DELTAthetaDELTA, DELTAthetag between the heater 8, and a liquid 1 and gas 2 become DELTAthetag>>DELTAthetaDELTA since the heat transfer rate in the liquid in the liquid is 500 - 800 and the heat transfer rate in the gas 2 is 10 - 100, and both of them can be discriminated surely. When thickness of an insulating plate 7 is thinned and a temperature fall generated during this time is made small enough, the temperature of the heater 8 can be regarded as the temperature of an inter face 11a of a thermocouple wire 11 as it is, and the measurement can be execut ed by a recording thermometer 16.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: B41J2/44
Filed: 1992-08-06
Abstract: PURPOSE:To obtain a color image forming device which can conduct high-quality image recording with an improved resolving power. CONSTITUTION:Image density data from an image density data storage circuit 210 is read by a reading circuit 220. In a pixel data conversion circuit 240, the data is subjected to a RE processing, wherein a target pixel is divided into small pixels and the density of the target pixel is distributed per small pixel in accordance with the distribution of adjacent pixel density data including the target pixel, and density data of a pixel center and a part adjacent to a pixel (a pixel-to-pixel part) are found. As a reference wave, a triangular wave B is generated by delaying a reference clock DCK0 by 1/2 period from a B clock obtained by a doubling inversion circuit 281 at twice the frequency of an original pixel clock. Density data per color is modulated on a reference wave signal by modulation circuits 260A, 260B. Pulse width modulation signals positioned on a pixel center and a pixel-to-pixel part are generated. In first and second scanning by two laser beams based on the moldulation signals, an image is recorded in main scanning and sub-scanning directions by an image exposure of a pixel center and a pixel-to-pixel part.

Title: Optical deflector
Inventor: ISHIZUKA YUTAKA
IPC: G02B5/08
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To provide an optical deflector capable of easily flushing away the cutting fluid adhered to the inside of a rotor case. SOLUTION: The part corresponding to the bottom wall of an annular recessed part of the rotor case 40 of the optical deflector 1 is a flange part 42 on which a rotary polyhedral mirror 7 is mounted. A through-hole 16 is formed in this part. Then, the washing liquid in the annular recessed part is smoothly discharged from the through-hole 16 at the time of degreasing and washing after machining of the rotor case 40 and, therefore, the easy flushing away of the cutting fluid from the rotor case 40 is made possible. Since the rotor case 40 is lighter by as much as the through-hole 16 is formed, a starting time may be shortened. Even more, the through-hole is closed by the rotary polyhedral mirror 7 in the assembled state of the optical deflector 1 and, therefore, the generation of a whistling sound and an increase in air resistance do not arise.

Title: Voltage comparator
Inventor: MORI SHINTARO
IPC: H03K5/08
Filed: 1991-08-22
Abstract: PURPOSE:To obtain a voltage comparator free from offset. CONSTITUTION:When a reset signal is 'H', transistors(TRs) Q12, Q14, Q16, Q18 are turned on. Thereby a capacitor C2 is discharged, the conductive resistance of a TR Q22 is increased and the 1st prescribed voltage V1 is impressed to the bases of TRs Q1, Q2. The conductive resistance of a TR Q24 is fixed and smaller than that of the TR Q22 and the output of an amplifier stage 5 is turned to 'L'. A charging means 40 charges the capacitor C2 with electricity in response to the output 'L', and when the conductive resistance of the TR Q22 is reduced and the output of the amplifier stage 5 is turned to 'H', the charging of the capacitor C2 is aborted. At this point of time, an offset voltage is canceled and currents flowing into respective TRs Q1, Q2 are made equal. When the reset signal is turned to 'L', the TRs Q12, Q14, Q16, Q18 are turned off. Thereby when voltage to a non-inverted input terminal 1 becomes equal to voltage to an inverted input terminal 2 in normal operation, an output is inverted.
