Title: Switching regulator
Inventor: YOSHIKAWA SHOZO
IPC: H02M3/155
Filed: 1994-04-28
Abstract: PURPOSE:To suppress the power loss of a switching regulator to a low level by controlling the regulator to turn off a second transistor when a first transistor is turned on and turn on the second transistor when the first transistor is turned off. CONSTITUTION:In a switching regulator, the emitter E and collector C of a transistor 20 and a resistor 21 are connected between the emitter E and base B of a transistor 2 and the base B of the transistor 2 is grounded through the collector C and emitter E of a transistor 23. In addition, the base B of the transistor 23 is grounded through a resistor 25 and also connected to the collector C of a transistor 8 through a resistor 24. As a result, the voltage across the collector C and emitter E of a first transistor is suppressed to a low level and the power loss of the switching regulator is reduced when the first transistor is turned on, because a sufficiently large base current flows and turns on the transistor. When the first transistor is turned off, the power loss of the switching regulator is also reduced, because the transistor is turned off in a short carrier storing time.

Abstract: PURPOSE:To effectively prevent the generation of soft error without decreasing the throughput of solder bump forming process by leaving a part of a metal film for solder substratum electrode stuck on a passivation film of a semiconductor wafer, above an integrated circuit forming region. CONSTITUTION:By using sputtering method or the like, thin films of, e.g., chromium (Cr), copper (Cu) and gold (Au) are stuck in order on the surface of a wafer 1; these thin films are etched by using a resist mask; a solder substratum electrode 5 is formed on the surface of an Al electrode pad 4; an alpha-ray shielding layer 6 is formed above an integrated circuit forming region. After a solder film composed of tin(Sn)-lead(Pb) alloy is selectively stuck on the surface of the solder substratum electrode 5, said solder film is subjected to wet-back in a reflow furnace, thereby forming a hemispherical solder bump 7.

Abstract: PURPOSE:To obtain an Al sintered body in which the generation of pores is suppressed and excellent in wear resistance and heat resistance by compacting and sintering composite particles obtd. by coating and fixing the surface of ferrous metallic particles with Al particles and subjecting this sintered body to high frequency heating. CONSTITUTION:Ferrous metallic particles pulverized into about 20 to 500mum are mixed with about 30wt.% Al particles having the particle size of about 1/10 to that of the above ferrous metallic particles. This mixture is treated by an electrostatic depositing method to deposit the Al particles on the surface of the ferrous metallic particles, which is thereafter treated by a stirrer having a high speed rotary vane. In this way, the surface of the ferrous metallic particles is coated and fixed with the Al particles in the shape of a capsule. The composite particles obtd. by the above method are charged to a sintering die as a raw material and is sintered under prescribed pressure at prescribed temp. for prescribed time. The sintered body with a prescribed shape obtd. by the above method is subjected to high frequency heating. By this heating treatment, the coated Al particles are melted to precipitate chilled matter constituted of intermetallic compounds on the boundaries between the ferrous metallic particles and the Al particles as well as each Al particle is metallically bonded. In this way, pores are removed to improve the heat resistance and wear resistance of the Al sintered body.

Title: Method and apparatus for preventing river from meandering of water, scraping and erosion of bank
Inventor: KANEKO SHIGERU
IPC: E02B3/04
Filed: 1982-07-02
Abstract: PURPOSE:To suppress the erosion of river bank due to meandering of river water by artificially changing the flowing direction of the river water. CONSTITUTION:Plural flow-changing guides 1 provided with plates 3 inclined in the face of the flow-down direction of water are set on the bottom of a river. The original meandering of the river water is suppressed by concentrating the main stream of the water flow on a fixed direction in such a way as to gradually correct it in the straight direction. When plural flow-changing guides 1 are settled and set at intervals in one line on the bottom of the river 10, the main stream of the river water collides on the plates 3 and is directed toward other directions to erode the left expanded bank L, and thereby soil and sand are gradually deposited on the eroded right bank R. Therefore, the curved part of the meandering area 11 is gradually corrected into straight form.

Title: Control rod assembly
Inventor: ADACHI SHIGERU
IPC: G21C7/14
Filed: 1992-05-08
Abstract: PURPOSE:To raise the response characteristics to coolant temperature rise and suppress the change of core insertion length for the change in temperature during normal operation by passing liquid metal in a sensing part and bellows and outside of sensing part through a small hole closed in an abnormal situation. CONSTITUTION:If coolant temperature rises in abnormality of a reactor, the temperature around a sensing part 29 also rises. As the part 29 is a thin cylinder shape, the inside liquid metal 32 temperature also rises with almost no time delay and the volume expands. A bimetal 36 is set to block a lid 35 of a small hole 34 at the temperature over near the temperature of the metal 32 during a rated operation and so the liquid 32 does not flow out of the small hole 34 and flows in a bellows 28. Thus, the bellows 28 expands to insert a control rod into the core. As the bimetal 35 becomes below the temperature in rated power operation during a normal startup and normal shutdown, the lid 35 does not block the small hole 34, the metal 32 in the part 29 and the bellows 28 is discharged out of the part 29 or absorbed from the outside of the part 29. Therefore, the bellows does not expand and contract and so, no insertion and withdrawal of the control rod takes place.

Filed: 1989-05-09
Abstract: PURPOSE:To enhance the filled rate of an insulating material, electrophotographic characteristics, such as photosensitivity, and mechanical strength by electrolytically treating a porous oxide film by a pulsative flow containing a negative component. CONSTITUTION:The conductive substrate is subjected to a primary electrolytic treatment to form the porous oxide film, and this is subjected to a secondary electrolytic treatment by using the pulsative flow containing the negative component to form fine pores freed of ruggedness on the walls of the fine pores and enhanced in smoothness of the walls. When the secondary electrolytic treatment is executed for a long time by using the pulsative flow containing only the negative component, it is probable for the interface between the conductive substrate and the porous oxide film to be peeled off, and therefore, it is preferred to set a time length by considering the strength of the porous oxide film and the smoothness of the fine pores, thus permitting the obtained electrostatic recording body to be enhanced in the filled rate of the insulating material and improved in the electrophotographic characteristics, such as photosensitivity, and superior in mechanical strength.
