IPC: H05K3/34
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To avoid pickup failure or place failure, by vacuum-chucking conductive balls to suction holes with a vacuum-chucking tool being ultrasonically vibrated, and stopping the tool from vibrating when a given vacuum is reached in the tool. SOLUTION: When a vacuum-chucking tool 32 is lowered in a vessel 14, air is blown into the vessel 14 from below to fluidized solder balls 1 stored in the vessel 14, while the tool 32 is ultrasonically vibrated, relative to the solder balls 1 to thereby quickly and stably vacuum-chuck the balls 1. When a given vacuum is reached in the tool 32, the balls 1 are led to all suction holes of the tool 32 and the ultrasonic vibration stops, if the purpose of applying this vibration is approximately attained.
Patent JP-H06173984-A (JP)
Title: Brake frictional member
Inventor: TAKEI YOSHIKI
IPC: C04B38/02
Filed: 1992-11-30
Abstract: PURPOSE:To provide a brake frictional member where a fade phenomenon is restrained and a constant abrasion resistance is expected by setting a big porosity without reducing a pressure in molding and a temperature in baking. CONSTITUTION:Since antimony pentasulfide is used as a blending component of a lubricant, the antimony pentasulfide is decomposed into antimony trisulfide and sulfur at the time of baking. The sulfur is reacted with oxygen in the atmosphere, to be turned into sulfur dioxide for gasification. A pore is formed in a portion where the sulfur dioxide is produced, thereby obtaining a brake frictional member of high porosity. In the brake frictional member, gas generated by decomposition of the blending component at the time of braking easily escapes to the outside through the pore. Accordingly, it is possible to prevent a drop of a friction coefficient at the time of braking, resulting in enhancement of brake performance. Moreover, constant abrasion resistance can be expected because it is unnecessary to reduce a pressure in molding and a temperature in baking in order to enhance porosity in the same manner as conventional.

Title: Acceleration detector
Inventor: OBAYASHI HIROAKI
IPC: G01P15/135
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the chattering of a reed switch with a compact and simple device by allowing a sealed magnetic fluid to interlink the magnetic flux of a magnet to a contact and closing the switch when deceleration is reduced and the reed switch is pushed. CONSTITUTION:Normally, a magnet 6 is energized by a spring 7 and one edge of a cavity 5 is pressed. When a large deceleration is applied, the magnet 6 moves to the contact part of a reed switch 1 against the pressing force of the spring 7, at the same time, a magnetic fluid 8 also moves to the contact part, and the magnetic flux of the magnet 6 interlinks with the contact part of the switch 1 for closing circuity. When the deceleration is reduced momentarily after the closing, the magnet 6 is pushed back by the retrieval force of the spring 7 and then leaves the contact part of the switch 1. However, a magnetic fluid 8 remains as it is for a while near the contact part due to the viscosity, the magnetic flux of the magnet 6 continues to be interlinked with the contact part, thus maintaining closed state and hence preventing chattering when the deceleration is reduced momentarily.

CONSTITUTION:A core fitting 1 is clamped to a car body 18, and an outer casing fitting 2 is surrounded concentrically with this core fitting 1, while a toroidal vibrationproof base body 3 is installed interposingly between these elements. In addition, an elastic film 4 is set up in space between both the fittings 1, 2, and thereby a liquid chamber 9 is formed. Moreover, a partition body 5, partitioning off this chamber into two upper and lower chambers 9A, 9B, is set up in the liquid chamber 9, and this partition body 5 is formed of a partition ring 10 with an orifice 13, a press-in ring 11 and a rubber plate 12.

Title: Disk access control method for disk controller containing cache
Inventor: AKATSU MASAHARU
IPC: G06F3/06
Filed: 1988-12-23
Abstract: PURPOSE:To improve the cache availability by using no path having a cache access fault and inhibiting the use of a cache in case the number of practicable storage paths is small in a path group and setting the halted path in an available state again. CONSTITUTION:The paths having the cache access faults are not used to the disks 2 and 3 which perform the accesses with use of caches. At the same time, the paths which have the cache access faults are halted when these faults occurred in a disk controller 1. Thus the application of caches is continued. Then the application of caches is inhibited to the access requests to the optional disks 2 and 3 given from an optional path group in case the number of storage paths (SP) which are practicable with use of caches is small within a path group. Then the paths halted due to the cache access faults are available again. Thus the cache availability is improved.

Title: Speed change control device of automatic transmission
Inventor: IWATSUKI KUNIHIRO
IPC: F16H63/50
Filed: 1989-12-13
Abstract: PURPOSE:To make a clutch-to-clutch speed change possible with a small speed change shock by providing such constitution as to reduce engine torque while to hold it almost at a fixed value during a hold control. CONSTITUTION:During a hold control, engine torque is positively reduced and held almost at a fixed value in no relation to an accelerator pedal. Accordingly, responsiveness is improved, because torque, given to friction engaging device C2, B2, is decreased by the amount of reducing the engine torque, and a rotational speed is quickly changed by a similar change of oil pressure. Furthermore, because the engine torque is not only reduced but also held almost to the fixed value, a feedback control is made executable in good stability without generating a disturbance such as change of the engine torque. As a result, hold performance in the vicinity of a synchronous rotational speed can be improved, and a clutch-to-clutch speed change can be realized by a small speed change shock.

Title: Electrification removing device for color cathode-ray tube bulb
Inventor: MASUDA ATSUSHI
IPC: H01J9/24
Filed: 1989-12-15
Abstract: PURPOSE:To remove the electrification of a glass bulb by sliding a high- elasticity conductive-fiber-made electrification removing brush, which is in a well grounded state, in contact with the whole outside of the bulb. CONSTITUTION:An electrification removing brush 2 is made of high-elasticity strong carbon fiber which is given good conductivity by mixing good conductor powder such as Al in. A column 3 is made from a normal iron pipe or, etc., because it requires enough strength. A conductor often has floating potential near a high-voltage generator or a high-voltage charged subject and so an insulating coat is applied to the periphery of the column 3 to be insulated from the electrification removing brush 2. The electrification removing brush 2 is directly grounded with a fully sized cooper wire instead. The electrification removing brush 2 is slided in contact with the whole outside of the bulb of a color cathode ray tube 1 several times at preset intervals. It is thus possible to remove the electrification of a glass bulb in production.
