Title: Colorimetric thermometer
Inventor: OKUHARA SEIICHI
IPC: G01J5/60
Filed: 1982-02-01
Abstract: PURPOSE:To use the titled thermometer in a field requiring fine temperature  control by precisely indicating the temperature in a limited narrow measuring  range (1,100-900 deg.C e.g.,) under linearized state. CONSTITUTION:Radiant light from a body 9 to be measured is converted into DC through a filter 10, a photoelectric conversion element 15 and a rectifier circuit 18 and latched in a latch circuit 34 through a V/F converter 20, a counting circuit 22, etc. Subtracting circuits 36, 37 find the difference P-Q of counting values between counting circuits 23 and 24 and that Q-R between the counting circuits 24 and 25 respectively and output these difference values to D/A converters 39, 40 to convert the values into analog values. Since the output voltages of operational amplifiers 42, 43, are fed back to the reference voltage input terminals of the converters 39, 40 and reference voltages or analog output  voltages are applied to the input terminals of the operational amplifiers 42, 43,  the analog output voltages of the converters 39, 40 are made equal to reference voltage Vs independently of the counting values of the subtracting circuits 36,  37. Consequently the temperature in a limited measuring range can be precisely  indicated under the linearized state.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/01
Filed: 1988-01-27
Abstract: PURPOSE:To prevent deterioration in image quality by providing a means discharging to a photosensitive body with electric charges of polarity opposite from the image part of the photosensitive body, and a means uniformly projecting light possessing wavelength transmitting toner on the photosensitive body almost at the same time as discharging, after a developing step and before a transfer step. CONSTITUTION:A discharger/exposer 10 is provided between a developing unit 4 and a transfer electrode 5. The photosensitive drum 1 is electrified at -700V, for instance. Here, the light source 14 of the discharger/exposer 10 uniformly projects light on the photoconductive layer surface of the photosensitive drum 1, and simultaneously an electrode 12 discharges positive electric charges, whereby negative charges on the photosensitive body in a positive toner adhering part disappear to lower the potential. In case of electric charges in a part lower than the toner, it can also be exposed when wavelength transmitting the toner is employed as that of light from the light source 14. Thus, toner scattering is reduced to prevent deterioration in image quality.

Title: Electric-resistance hot caulking method
Inventor: ENDOU JIYUNJI
IPC: B21K25/00
Filed: 1980-02-08
Abstract: PURPOSE: To shorten the working time, and to save the energy consumption, by utilizing a general-purpose spot welder for simultaneously effecting the heating and pressing work.  
     CONSTITUTION: When the general-purpose spot welder is started, the upper electrode 1 goes down and presses the thin diameter head 8 of the caulking pin 3; thereby, a specified electric current flows across the upper electrode 1 and the lower  electrode 2 through the caulking pin 3. Since the thin diameter part 3a of the caulking pin 3 possesses a smaller sectional area as compared with the large diameter  part 3b, the thin diameter part 3a develops heat to red-hot earlier than the large  diameter part 3b. The red-hot thin diameter part 3a of the caulking pin 3 is  smashed and deformed by the pressure of the upper electrode 1, and is formed into the caulked heat 9; hereby, the caulking pin 3 is solidly caulked to the work 4. At the stage that the caulked head 9 is formed, the electric current is put off, the upper electrode 1 goes up and returns to the initial position.
