IPC: G03F1/34
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To prevent production of pattern errors by forming a conductive transparent layer on a transparent substrate, forming plural light-shielding layers with a specified interval on the conductive transparent layer, and forming a hemispheric shifter between a pair of light-shielding layers in such a manner that the shifter has a flat upper face and a round side face. SOLUTION: A conductive transparent layer 10 is formed by vapor deposition on a transparent substrate 1, on which a square shifter comprising an inorg. photosensitive agent 19 doped with silver is formed. Further, the square shifter is heat-treated to form a hemispheric shifter 21. A second inorg. photosensitive agent 17 is applied on the whole surface of the conductive transparent layer 10 including the hemispheric shifter 21. Then, the second inorg. photosensitive agent 17 is ground till a part of the surface of the hemispheric shifter 21 is ground. Then, the second inorg. photosensitive agent 17 remaining is removed by using an alkali developer to form a shifter 22 having a flat upper face and a round side face.  Thereby, the shifter 22 on the front and back surface maintains a hemispheric state of the side wall where no inorg. photosensitive agent 19 (light-shielding layer) doped with silver is deposited.

Title: Kerosene burner
Inventor: SHIMIZU EIJI
IPC: F23D3/10
Filed: 1982-04-21
Abstract: PURPOSE:To prevent a flame from extending outside a device, by a method wherein a panel for preventing the production of an upright flame is located above a flame spreading panel and separately from the latter panel in a manner that the former panel covers an upper part of a gas between an outer shell of a combustion cylinder and an inner or an outer flame cylinder. CONSTITUTION:A plurality of leg parts 14 are located above a flame spreading panel 13, and a panel 15 for preventing the production of an upright flame, positioned above gaps between inner and outer flame cylinder 10, 11 and the outer flame tube 11 and an outer shell 12, is separately installed. This constitution causes a flame, naturally growing into a large upright flame, to move outwardly by dint of the panel 15, whereby an upright flame 16 decreases in height and is well mixed with secondary air, which results in reducing a quantity of an upright flame itself and in maintaining the safety. The narrower a gap A between the panel 15 and the outer shell 12 is, the more favorable it is for the prevention of the occurrence of an upright flame, but reversely, the larger a pressure loss is, which results in causing a turbulence of combustion, e.g., the reduction in a quantity of combustion heat, an increase in carbon monoxide in combustion waste gas, the production of a combustion noise due to a lift phenomenon of a flame, whereby the gap is decided from two factors of the prevention of the occurrence of an upright flame and the combustion properties.

Filed: 1986-03-26
Abstract: PURPOSE:To automatically stop the control of hot water supply and additional burning when water leaks or in the case of a water level at which additional-burning is impossible by providing a ultrasonic wave sensor for detecting the water level of a bathtub. CONSTITUTION:A ultrasonic wave sensor (c) is fixed to the upper part within a bathtub (a), and transmits a sound wave on the surface of hot water and a sound wave being reflected is outputted to a controller (i) as a detection signal. When an automatic hot water supply switch is turned ON, an automatic draining device (b) is closed. Hot water supply is started and a set hot water quantity is judged in the control means (i) based on the ultrasonic wave sensor (c). Simultaneously with the starting of hot water supply, a variation in the rise of a hot water level at a predetermined time is detected. When the amount of variation becomes less than a set reference variation amount, it is judged by control means (i) as a water leakage. In this case, an alarm is emitted, and respective valves for supplying a gas for hot water supply, for water supply and hot water supply, are closed. Then, the operation of a hot water supplier (g) and hot water supply are stopped. When simultaneously with the termination of automatic hot water supply, the automatic additional-burning control is started, the amount of hot water within the bathtub (a) is detected by the ultrasonic sensor (c), and when the water level is found higher than the set water level at which additional burning can be made, additional-burning is started, and an additional-burning timer is started to clock the time.

Title: Self-diagnosing device for computer

IPC: G06F11/30
Filed: 1987-03-24
Abstract: PURPOSE:To perform an optimum processing in response to the type of abnormality by distinguishing a program runaway state from a hardware trouble state and producing repetitively the watch time-out signals to output alarm signals at the hardware trouble state. CONSTITUTION:In the program runaway state the transmission of a WDT clear signal S1 is stopped for a WDT computer 31 and a time-out signal S2 is outputted from a watching timer 32 after a prescribed time. Thus the computer 31 is reset and the signal S1 is outputted again. While in the hardware trouble state the signal S2 is outputted and the computer 31 is reset. In this case, however, a state where no signal S1 i produced is continued therefore, the signals S2 are repetitively produced from the timer 32. Then an alarm signal S4 is outputted when the signals S2 are produced by a diagnozing counter 36 more than the prescribed frequency within the prescribed time of a check timer 34. In such a way, the optimum processing is possible in response to the type of the abnormality.
