Title: Ignition confirming apparatus
Inventor: IWAMOTO RYUSHI
IPC: F23N5/10
Filed: 1987-05-18
Abstract: PURPOSE:To permit the visual confirmation of ignition by an operator indirectly while standing up, by a method wherein the ignition is informed of by indication when the thermal electromotive force of a thermocouple provided in a combustion unit has become a given value or higher, thereafter, the indication is extinguished when a given time has elapsed. CONSTITUTION:When there is no thermal electromotive force in a thermocouple T, the output of a comparator 34 shows H-level by resistors 8, 9, 10. However, when the thermal electromotive force of a given value or higher is generated, the plus input voltage of the comparator 34 is reduced and the output of the same is converted into L-level. Accordingly, transistors 27, 31, 30 are operated and a LED 32 is lighted. The transistors 26, 29 are operated simultaneously with the lighting of the LED 32, therefore, the discharge of a charge from a capacitor 35 is started. When the voltage of the capacitor 35 has become lower than a voltage, set by the resistors 10, 20, (after a given time (t)), the output of the comparator 33 shows H-level and the LED 32 is put OFF.

Filed: 1978-10-02
Abstract: PURPOSE: To prevent unnecessary on-off control of a compressor and conduct smooth air conditioning within a set temperature range by employing cooling capability corresponding to cooling load based upon the functions of temperature regulators or timer circuits.  
     CONSTITUTION: The air conditioning apparatus inverts flip-flops 14W16 with H  level outputs one by one from the host level to the L level when a detecting temperature t is lower than t 1  at intervals over a set time to a time curcuit 11 by on-off  operation of temperature regulators 7, 8 and by operation of each gate 9, 10. When  the detecting temperature t is higher than t 2 , flip-flops 14W16 with L level outputs  are inverted one by one from the lower level to the H level. In this way the refrigerating cycles of each line are controlled by controlling electromagnetic contactors  1W3 by turns. It makes greatly easy to keep a prescribed temperature in order to  output smoothly the cooling capabilities corresponding to cooling loads.

Title: Material for packaging electrophotographic sensitive body
Inventor: NAKAGAWA MASARU
IPC: G03G15/00

Abstract: PURPOSE:To prevent white dropout of image density due to electric charge memory and to obtain a high-quality image by using a material containing a conductive material. CONSTITUTION:The packaging material contains the conductive material and has an intrinsic volume resistivity of <=10OMEGA.cm. When the packaging material higher in electron donativity than the binder resin of the surface of the photosensitive body, negative charge is given to said surface.

Filed: 1983-07-04
Abstract: PURPOSE:To attain a superior display function of no parallax without adding two filters newly, by arranging a color optical filter on each electrode of a thin film transistor array and giving different spectral characteristics to adjacent filters and overlapping them in their peripheral regions and giving a specific film thickness to them. CONSTITUTION:This film transistors 2, 2'', 2'', and 2''' are arranged in hatched parts between gate lines 1a, 1a' and 1a'' and source lines 3, 3', and 3'', and opical filters 20, 21, and 22 are formed on them. Filters 20, 21, and 22 have spectral characteristics different from one another and adjacent elements overlap one another. In this constitution, the parallax is not generated because filters are brought closely into contact with electrodes of a display part. Because of overlapping, the effect of absorption of an incident light is enhanced. Films of filters are formed easily by sublimation transfer or vapor-deposition. It is good that the thickness of the color filter layer is 0.1-3mum normally, and desirably, 0.5-1.5mum thickness is selected together with an optimum light absorbance.
