Title: Traction control device
Inventor: KUMEMURA YOUICHI
IPC: B60T8/58
Filed: 1990-11-14
Abstract: PURPOSE:To eliminate phase inversion of wheel speed and improve acceleration performance in a split road surface by controlling right and left wheels independently respectively when split rate difference between right and left driving wheels is less than a preset value, and controlling them at the same time when it is more than the preset value. CONSTITUTION:The output signals of a driving wheel speed sensor 31 and a driven wheel speed sensor 32 are inputted, and in a controller which controls brake liquid pressure by controlling opening and closing of solenoid valves 19, 29, there is an independent/simultaneous control decision part 40. When a slip rate difference DELTAS outputted from a slip rate comparison part and a slip rate difference computation part 38 is less than a prescribed value DELTAS1, increase/decrease pressure signals for a mode outputted from a driving wheel slip condition computation part 39 as independent control are outputted to right and left driving wheel brake control parts 41. When the slip rate difference DELTAS is more than the preset value DELTAS1, on the other hand, increase/decrease pressure signals for a mode outputted from the driving wheel slip condition computation part 39 for a driving wheel with larger driving wheel slip rate S are outputted as simultaneous control.

Title: Plastic bga package
Inventor: HIDAKA AKIHIRO
IPC: H01L23/12
Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To improve the package performance of plastic BGA packages. SOLUTION: A semiconductor chip 22 is bonded to the top surface of a BGA substrate 21 (plastic substrate) with an adhesive such as Ag paste and is encapsulated with an encapsulating resin 23, and many solder balls 24 are arranged on the bottom surface of the BGA substrate 21 as connection electrodes. The solder balls are separated by more than 1 mm to the outer side and, preferably more than 2.5 mm to the outer side from the die bonding region.  When this plastic BGA package mounted on a circuit substrate 25 is subjected to a temperature cycling test, the maximum shearing strain of the solder ball 24 can be reduced to about 60% or smaller than that in the conventional case (50% or less when the solder ball is separated by 2.5 mm or more from the die bonding region), even if a gap between substrates 21 and 25 is not packed with the adhesive resin, thus greatly reducing the defects of cracks of the solder ball 24.

Title: Insert molding method
Inventor: HIROZUMI MASAO
IPC: B29K105/22
Filed: 1993-12-08
Abstract: PURPOSE:To uniformly apply a coating of a resin around a shaft material by a method wherein a mold composed of a plurality of split molds is used, and the shaft material is held by holding pins provided at one or more positions for every split mold. CONSTITUTION:At both ends of a stationary mold, the shaft ends of an insert shaft 3 are attracted by the force of a magnet or the like. After the mold is closed, slide cores 21, 23, and 22, 24 on a movable mold are actuated. After the actuation is perfectly completed, the held insert shaft 3 is positively fixed by six holding pins at the center thereof. Next, in an injection process, molten resin is injected from a gate. Just under the gate, the molten resin creeps to the both sides of the insert shaft 3 to reach the side of the insert shaft opposite to the gate, simultaneously being charged into the both ends in the axial direction of the insert shaft 3. Therefore, the coating of the resin is uniformly applied to the peripheral surface of the insert shaft 3. A complete insert molded article is obtained by opening the mold after dwelling and cooling.

Title: Water hammer buffering device
Inventor: YAMADA YUTAKA
IPC: F16L55/04
Filed: 1989-11-29
Abstract: PURPOSE:To prevent the second pressure wave from being generated by collision by setting the spring force of a spring which forces a piston in a cylinder chamber which buffers water hammer to a communicating opening side at such strength as the piston stops before it comes into contact with the rear edge part of the cylinder chamber with water pressure. CONSTITUTION:When a venturi tube 18 is installed inside a water flow passage, and when flow is generated, a low pressure part occurs in a throttling part 20 and a piston 34 in a cylinder 26 fully goes down. After the water flow is suddenly stopped, the water flow of high pressure passes through the hole 22 of the throttling part 20. Then the piston 34 is raised to absorb water hammer. The spring force of a spring 38 which forces the piston 34 is set at such strength as the piston 34 stops before it collides with a cap 32 at the rear edge part of the cylinder. It is thus possible to absorb water hammer by retracting the piston 34, and prevent the piston from colliding with the cap 32 at the time of retraction, and the second pressure wave from being generated by collision.
