Inventor: TAKAYASU HIROSHI
IPC: B23K20/00
Filed: 1986-02-03
Abstract: PURPOSE:To improve the nitric acid resistance and strength on the joining part of the container in which the nitric acid of high concentration exists by providing the intermediate material which forms the total rate solid solution with stainless steel to the stainless steel side and the intermediate material which forms the total rate solid solution with both intermediate products of Ti and stainless steel side on the Ti side and joining both intermediate materials. CONSTITUTION:This invention is a method to prevent the generation of the reduction in the mechanical property and reduction in local nitric acid resistance due to the existance of the various intermetallic compounds which are formed at the vicinity of the junction part in case of joining SUS 304L base metal and Ti base metal. Namely in case of performing the diffused junction of SUS 304L of the base metal 1 and the Ti of the base metal 2, the diffused junction is performed with the prescribed joining temp., pressure, joining time and degree of vacuum by interposing V at the SUS 304L side of the base metal 1 and Mo at the Ti side of the base metal 2 respectively, taking into consideration of the formation of the intermetallic compound. In this way it can be restrained that the intermetallic compound compound which is in fear of its weakness and the reduction in the nitric acid resistance is generated on the junction part.

Title: Exhaustion preventive device for vaporized fuel
Inventor: SONODA HIDEFUMI
IPC: F02M33/00
Filed: 1987-02-02
Abstract: PURPOSE:To provide a vaporized fuel exhaustion preventive device for a fuel tank used on a car, wherein a valve device is made in small size and light weight, by arranging at the tank upper wall the valve device mounted on a breather pipe to put the tank in communication with a vaporized fuel suction device, and moving the valve horizontally. CONSTITUTION:A solenoid valve 54 is moved in the horizontal direction according to an oil supply signal from an oil supply sensing means to cause moving apart from a valve seat 68. At this time, the liquid level in a tank 10 is low and a float 56 is apart from a valve seat 76, so that inside of the tank 10 is in communication to a charcoal canister via a valve passage 66 and a breather pipe 44 to allow suction of the vaporized fuel and air bleeding, and thus fuel supply can be done. When the liquid level rises and the tank is filled, the float 56 seats itself on the valve seat 76, followed by stop of air bleeding, stop of oil supply, and restriction of the liquid level. This constitution enables making the vale device in small size and light weight.

Title: Reliability control device for plant
Inventor: TAKAHATA YOSHIAKI
IPC: F23G5/50
Filed: 1991-02-14
Abstract: PURPOSE:To eliminate a matter of contradicting an automatic operation such as an assignment of an abnormal state assisting person by a method wherein data calculated and processed on the basis of one detected data of the process data sensing means and the other data while being in a cooperative relation are compared from each other and a control operation is continued with an abnormal state control means when an abnormal state occurs. CONSTITUTION:Signals of process data sensing means such as various temperature sensors 15a to 15d and gas sensors disposed within a combustion chamber 2 are inputted to a combustion control device 16 and then a driving speed of a pushing device 5 and speeds of stokers 2a to 2c are controlled in such a way as a combustion temperature detected by a temperature sensor 15a at an outlet port of a furnace becomes within a predetermined range. This combustion control device 16 calculates one data in reference to the other data of the signals of the process data sensing means which are cooperative from each other, judges it abnormal when the other detected value exceeds a predetermined range of the result of calculation, makes a pseudo judgement over it as a normal data with an abnormal state occurrence control means and then continues to perform a subsequent control. Accordingly, even in the case that the process data sensing means shows a trouble, a continuation of an automatic operation can be realized and then a waiting action for assigning an abnormal state assisting person can be prevented.

Abstract: PURPOSE: To operate refining continuously, by setting a flux-discharging means at a down-pipe hanging down at the opposite side of a vacuum vessel to the flux- charging side, and by specifying the depth of the upper surface of the down-pipe from the free surface of the molten iron so as to make unnecessary the descending- flow-producing blades for discharging flux having completed the reaction.  
     CONSTITUTION: Risers 101W104 and down-pipes 201W204 both hanging down from the double bottom of a vaccum vessel are dipped in the molten iron flow in a gutter 1. The upper surface of the down-pipe 204 which forms a discharging means for the flux having completed reaction is positioned higher than those of the down-pipes 201W203. The depths of the upper surfaces of the down-pipes 201W203 from the free surface of the molten iron are set larger than the critical diving depth for producing swirls of sucking the gas in the vessel 2 and the flux which is charged from a storage tank, while the depth of the upper surface of the down-pipe 204 from the free surface of the molten iron is set smaller than the critical diving depth described above. Hereby, swirls sufficient to suck flux which has completed reaction and which is floating on the molten iron free surface are produced, so that the flux is discharged from the vessel 2.

Title: Dehumidifier
Inventor: ADACHI MASAAKI
IPC: F24F1/02
Filed: 1978-02-24
Abstract: PURPOSE: To continually perform a dehumidifying run with high efficiency, by connecting an electronic cooler and a DC fan motor in parallel with power and shifting the polarity of the power in response to a defrosting signal.  
     CONSTITUTION: When the contacts of polarity shifting switches 10, 11 and a defrosting detector 12 are connected as shown in Fig., the temperature of a heat transfer surface 2a and a fin 3a of the electronic cooler 1 is low and the temperature of a heat transfer surface 2b and a fin 3b of the cooler 1 is high. A that time, air is caused by a fan driven by the DC fan motor 4 to flow into a casing 6 and be dehumidified and flow out of the casing in the direction of the full line arrows. When the moisture in the air is condensed and much frosted on the heat transfer surface 2a etc., the defrosting detector 12 operates to connect its contacts 12a, 12c to each other and the polarity shifting switches 10, 11 are actuated through a relay 13 to reverse the operation of the electronic cooler 1 and the fan. Thus, the air is efficiently dehumidified after the defrosting.

Title: Lens barrel for zoom lens
Inventor: TANAKA KAORU
IPC: G02B7/04
Filed: 1989-01-30
Abstract: PURPOSE:To obtain a large zoom ratio without being affected by the weight of an inside cylinder projecting from an outside cylinder and a lens group nor the rotary moment by zoom driving by maintaining the same fitting state as that when a moving cylinder is stored even when a moving cylinder is extended. CONSTITUTION:The zoom lens has a fixed lens barrel and the moving cylinder 7 which is fitted to the internal peripheral surface of the fixed lens barrel and projects from and sinks in the fixed lens barrel in the direction of the optical axis. When the zoom lens is in feeding-in/out operation, a rotary advance cylinder 7 moves in the direction of the optical axis while engaging the fixed lens barrel at all and the rotary advance cylinder 7 is engaged with a guide ring 29 at all times at the camera-body side position where the gear part 7a of the rotary advance cylinder 7 is formed. Therefore, the rotary advance cylinder 7 is prevented from slanting to the fixed lens barrel by the movement of a gear driving part which is generated in the lens barrel extension nor the weight of the lens itself which is extended out. Consequently, the force such as the cylinder or lens weight and the rotary moment of the gear driving part can be supported sufficiently to prevent the optical axis from slanting, so that a larger zoom ratio than before can be set.
