Title: Hydraulic device of work machine
Inventor: KOBAYASHI TAKAHIRO
IPC: F15B11/04
Filed: 1993-12-28
Abstract: PURPOSE:To improve operability and prevent cavitation by controlling an inflow side throttling area according to an operation quantity, reducing at the same time an outflow side throttling area according to the reduction of inflow side pressure by controlling fixedly pressure difference between inflow side throttle inlet and outlet. CONSTITUTION:On the pressure oil inflow side of an actuator 1, pressure difference between inflow side variable throttle 4 inlet and outlet is maintained at a set value by means of a pressure difference controlling means 30, so an inflow quantity to the actuator 1 from a pump 2 is in proportion to the variable throttle 4 throttling area. As this throttling area is controlled according to the operation quantity of an operation lever 7 by means of a throttling control means 31b an actuator operation speed according to an operation quantity is obtained. Also, for example, in a case in which the direction of load has suddenly changed to the same direction with the operation direction of the actuator 1 from the opposite direction, an outflow side variable throttle 15 throttling area is reduced by means of a throttling control means 33 according to the degree of the reduction of inflow side pressure, so the sudden reduction of pressure on an inflow chamber side is restrained, and the generation of cavitation can be avoided.

Title: Field effect transistor
Inventor: KAYAMA CHIZURU
IPC: H01L29/78
Filed: 1989-12-21
Abstract: PURPOSE:To protect a field effect transistor against damage caused by the concentration of a current by a method wherein a high concentration layer of the same conductivity type with a base region is provided inside the base region where a channel is formed. CONSTITUTION:A P-well layer 2 is formed on an N-type silicon substrate 1 using an oxide film as a mask, and a P-base layer 3 is formed using a polysilicon film as a mask. A P<+>-base layer 4 is formed on the P-base layer 3 using a resist as a mask to lessen a parasitic bipolar transistor in base resistance after the P-base layer 3 is formed. As the P<+>-base layer 4 is formed, the base resistance of a parasitic bipolar transistor on the base layer of a field effect transistor becomes 1/3 or so as much as that of a conventional one. By this setup, a bias between a base and an emitter induced by a current which flows through the base of a parasitic bipolar transistor becomes small, so that parasitic bipolar transistor is hardly turned ON. Therefore, a field effect transistor can be protected against damage caused by the concentration of a current.

Patent JP-H08169548-A (JP)
Title: Lifter magnet
Inventor: NIWA HIDEO
IPC: B65G59/04
Filed: 1994-12-20
Abstract: PURPOSE: To make a lifter magnet useful for carrying a work by forming a pair of work attracting electrodes in double ring shapes juxtaposed with each other at narrow intervals in a bottom surface shape, and forming the respective ones in a downward projecting shape whose radial directional thickness dimension is small. CONSTITUTION: Work attracting magnetic poles B1 and B2 are formed in a narrow width W1 and W2, and an interval W3 between both is also formed in a narrow width. Therefore, magnetic resistance in a passage L2 reaching the uppermost work 2, a second work 2' existing under it, the uppermost work 2 and the other work attracting magnetic pole B2 from the work attracting magnetic pole B1, is far larger than magnetic resistance in a passage L1 reaching the other work attracting magnetic pole B2 by passing through only the uppermost work 2 from the work attracting magnetic pole B1. Therefore, a magnetic flux cal arriving from the work attracting magnetic pole B1 passes through the passage L1, and reaches the other work attracting magnetic pole B2.  As a result, since magnetic attraction force hardly acts between the uppermost work 2 and the second work 2' overlapping under it, only the uppermost work 2 can be reliably attracted and raised.
