Title: Dc/dc converter with automatic clear circuit of microcomputer
Inventor: YOSHIMOTO KANJI
IPC: G06F1/24
Filed: 1983-09-05
Abstract: PURPOSE:To prevent an erroneous operation of a microcomputer due to a slight variation in a drive voltage by providing an automatic clear circuit which sensitively detects the variation in the output voltage of the converter and generates a clear signal. CONSTITUTION:When the primary side input voltage VL decreases over the control capacity of a voltage stabilizer and the voltage VS of the secondary side falls, the Zener diode of a Zener diode 12 drops, but the base current of a transistor 5 flows even when the collector potential of the transistor 5 is fluctuated to the negative side. Accordingly, the contribution of the decrease of the Zener current is relatively low, and the base current of a transistor 17 for an automatic clear circuit largely drops that much. The collector potential of the transistor 17 becomes high level by the reduction of the base current, a clear signal is generated to stop the operation of a microcomputer.

Title: Apparatus for treating waste gas from painting process
Inventor: MINEMOTO MASAKI
IPC: B05C15/00
Filed: 1979-12-17
Abstract: PURPOSE: To separate paint mists from waste gas by a solvent in a compact installation without necessity of changing a filter, by arranging a mist separator at the lower part in an active carbon tower.  
     CONSTITUTION: A mist separator 2 is arranged at the lower part of an absorbing tower 3. In treating waste gas, the waste gas from a painting process is carried to the mist separator 2 by an air blower 1, where the mists are separated from the waste gas, and to the absorbing active carbon tower 3, where a solvent is separated from the waste gas by absorption and the treated gas is discharged. In regenerating the active carbon, heated vapor is introduced through an upper part of the absorbing tower, while the operation of the air blower 1 is stopped. The solvent is separated from the active carbon by the heated vapor, and falls to the mist separator 2 with the vapor. By this falling solvent, the mists are washed away from the mist separator. The solvent and the vapor are then carried to a consenser 4, condensed there, and divided to a solvent part and a water part by a solvent-water separator 5. The separated slvent is reserved in a waste solvent tank 6.

Title: Hot water feeder
Inventor: YOSHIDA AKIRA
IPC: F24H1/10
Filed: 1993-06-08
Abstract: PURPOSE:To prevent the undershooting of a temperature of hot water to be supplied and prevent cold water from being discharged at the time of resuming the supply of hot water by closing a bypass on-off valve when the supply of hot water is stopped and opening said valve in delay from a predetermined time from the starting of the resupply of hot water when the supply of hot water is resumed in the case where hot water is supplied at a low temperature. CONSTITUTION:In the case where a set temperature is low, when the supply of hot water is stopped, a bypass on-off valve 7 is closed and, when the supply of hot water is resumed, the bypass on-off valve 7 is opened in delay from a predetermined period of time from the starting of the resupply of hot water. Accordingly, when the supply of hot water is started, water is not fed through a bypass passage 4 because the bypass on-off valve is closed. By this method, even when a hot water temperature on the side of a heat exchanger 1 is in a low level, the undershooting of a temperature of hot water to be supplied, which has been caused in conventional feeders, can be prevented from occurring at the time of resuming the supply of hot water unless a hot water temperature on the heat exchanger side is lowered down to a set level or below.

Title: Production of metal oxide
Inventor: FUJITA MASATO
IPC: C01G49/02
Filed: 1990-06-25
Abstract: PURPOSE:To efficiently obtain a metal oxide from vapor of a metal compd. with an energy source at a low cost by causing an exothermic chain reaction of the metal compd. with an oxygen-contg. compd. under active seeds formed in a specified mode. CONSTITUTION:A gaseous oxygen-contg. compd. is made to exist in a system contg. a gaseous metal compd. causing an endothermic decomposition reaction at >=10<15> molecules 1ml concn. Part of the system is irradiated with energy beams having >=10<-4> J/cm<2> energy density and active seeds are formed from the metal compd. at high concn. at the irradiated part. An exothermic chain reaction of the metal compd. with the oxygen-contg. compd. is then caused under the active seeds to form a metal oxide. Since an oxidation reaction with oxygen takes place simultaneously with the decomposition of the metal compd. in the vapor phase, the metal oxide is easily obtd. Since the amt. of oxygen is easily controlled, the control of the amt. of the metal oxide is facilitated.

Abstract: PURPOSE: To prepare a reference board of a desired thickness for a radiation thickness meter by performing sputtering between a parent metal to be a reference board and a metal plate placed separately from said parent metal.  
     CONSTITUTION: Placed inside a vacuum container 11 in which an inert or active gas is sealed are an anode electrode 13 and a cathode electrode 14 each connected to the corresponding terminals of a DC source 12. On said anode electrode 13 a metal plate 15 is placed, while an said cathode electrode 14 a parent metal 16 to be a reference board is placed. When a current from the power source 12 is applied, under said condition, a glow discharge occurs between the parent metal 16 and the metal plate 15.

Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration rate in the light emitting characteristic of a light emitting element and to prevent burning by providing a timer circuit that interrupts an input signal to a drive circuit when it is received continuously for a prescribed time or longer to an input of the drive circuit.

Water glass or the like is used as a binder. By controlling the grain size distribution of the refractory material to 0 to 20 wt.% of the grains having >3.0 mm grain size, 35 to 45 wt.% of the grains having <=3.0 mm and >0.1 mm grain size, and 20 to 25 wt.% of the grains having <=1.0 mm and >0.1 mm grain size, and 20 to 25 wt.% of the grains having <=0.1 mm grain size, a material according to the closed packing density curve can be obtd.
