IPC: B23K9/167
Filed: 1989-02-13
Abstract: PURPOSE:To prevent the occurrence of defective welding, porosity and gas scum by providing a tapered electrode on the welding torch tip of welding equipment and forming the specified arc generating surface on the electrode tip. CONSTITUTION:The band-shaped metallic sheet 10 and 22 ends are subjected to TIG welding and joining by the welding equipment 24 and the welded and joined part is rolled by a rolling device to join the band-shaped metallic sheets 10 and 20 together. The tapered electrode 30A is then provided on the welding torch 30 tip of the welding equipment 24. The arc generating surface (lower end face) B formed of the circular flat surface having >=0.3mm diameter is formed on the tip of the electrode 30A. By this method, even if the arc length is changed suddenly on the welding starting end or the welding finishing end of the welding and joining part, an arc is prevented from becoming unstable.

IPC: C22C1/02
Filed: 1980-03-18
Abstract: PURPOSE: To prevent the generation of side arc in the arc melting and casting of an ingot for melting by carrying out the arc melting and casting after removing the surface layer of the ingot.  
     CONSTITUTION: Powder based on Mo powder and V powder is mixed, press molded, and heat treated to form an ingot for melting. After removing the surface layer part of the ingot by turning or other method, the ingot is arc melted and cast. By this method the segregated part of the surface layer is removed to smoothen the ingot. Accordingly, side arc phenomenon is not caused in the melting and casting, and the melt is accumulated from the bottom of a crucible in order. As a result, the desired Mo-V alloy is obtd.

Title: Ignition timing controller of internal combustion engine
Inventor: NOROTA KAZUHIKO
IPC: F02P5/15
Filed: 1988-02-17
Abstract: PURPOSE:To prevent knocking by determining whether the air-fuel ratio is in the rich or the lean region, learning the acceleration fuel incremental coefficient or the deceleration fuel decremental coefficient and compensating the ignition timing on the basis of the coefficient data obtained from the learning. CONSTITUTION:An error calculating means C operates the error of periods during which the output of an oxygen concentration sensor B detecting the O2 concentration in exhaust gas exhibits that the air-to-fuel ratio is nearer to the rich or the lean region than the target air-fuel ratio. During the acceleration determined by the acceleration or deceleration state determining means A, if the error is out of the primary specified region, that is, the air-fuel ratio exhibits the approach to the rich region or the lean region, a learning control means D learns an acceleration fuel incremental coefficient by which the error goes into the primary specified region, and similarly, during the deceleration, said means D learns an deceleration fuel decremental coefficient by which the error goes into the secondary specified region. Based on the learned data, an ignition timing compensating means E compensates an ignition timing. The quantity of adhesion deposit is predicted accurately to compensate the ignition timing, whereby preventing occurrence of knocking.

IPC: H05B33/12
Filed: 1989-02-14
Abstract: PURPOSE:To prevent the oxidation of a fluorescent layer and drive it with the low voltage by laminating films made of an oxide and films made of a nitride of the same element to constitute dielectric layers, and forming the face in contact with the fluorescent layer with the film made of the nitride. CONSTITUTION:Dielectric layers 13 and 15 are laminated with oxide films 20 made of silicon oxide (SiO2) and nitride films 21 made of silicon nitride (Si3N4). Faces of the dielectric layers 13 and 15 in contact with a fluorescent layer 4 are formed with nitride films 21 and 21. Since faces of the dielectric layers 13 and 15 in contact with the fluorescent layer 4 are formed with a nitride, the fluorescent layer 4 is not oxidized by the effect of the dielectric layers 13 and 15, the dielectric layers 13 and 15 are formed with two kinds of films of the oxide film 20 and nitride film 21, thus the nitride film 21 with a low dielectric constant can be made thin in thickness, and it can be driven with the low voltage.

Title: Fuel cooler for automobile
Inventor: MORIKAWA YOSHIYUKI
IPC: F02M37/20
Filed: 1979-03-23
Abstract: PURPOSE:To make it possible to prevent a vapor locking phenomenon of gasoline in a simple constitution by cooling a gasoline pipe communicating a gasoline tank with an internal combustion engine with a coolant returning to a compressor in a car cooler. CONSTITUTION:Circulation of a coolant starts when an engine 1 is driven and a refrigeration cycle is operated. And the coolant is compressed at first by a compressor 9, runs to a condenser 12 in a condition of high temperature and pressure and is liquefied by being cooled with a cooling fan 2. The liquefied coolant is led to an evaporator 13 and vaporized. Whereas, the coolant returns to the compressor 9 through a suction coolant pipe 10 of low temperature and pressure. Though the coolant gas is heated slightly during the work, its temperature is sufficiently lower than that of atmosphere surrounding a low pressure gasoline pipe 6 from a gasoline tank 7 to a pump 3. Accordingly, a vapor lock phenomenon of gasoline can be prevented by contacting the coolant pipe 10 with the low pressure gasoline pipe 6 and covering both with an adiabatic material 14.

Filed: 1988-02-17
Abstract: PURPOSE: To give successive impacts effectively to an object even in the a gravity state by supporting a striker having a certain mass on a rotary member while possibility of idling due to existence of a play is reserved and thereby lessening the vibration of the rotary member or the device body during operation. CONSTITUTION: When an impact working member 16 is pressed to an object, the shank 16a of the working member 16 is positioned at the uppermost in the strokes. Then a rotary member 2 is rotated, and the peripheral surface of a columnar striker 11 pressed to the inner wall of a retaining hole 10 is allowed to run against the top of the shank 16a by the centrifugal force so that an impact force in the axial direction is given to the impact working member 16. At this time of running against the shank top, the striker 11 idles within the hole 10 in the direction opposite the rotary member rotating direction, and the impact repulsive force which the striker 11 receives from the working member 16 is absorbed by the idling. As a result, the impact repulsive force is not substantially transmitted to the body casing 1 through the rotary member 2.  Therein the frictional heat is less generated, as rubbing of the striker 11 with the top of the shank 16a lessens.
