Abstract: PURPOSE:To obtain an electrical laminate having a low thermal expansion coefficient and a low dielectric constant by disposing a backup board for supporting a wiring board through a bonding material layer and including a low thermal expansible alloy layer in the bonding material layer. CONSTITUTION:An electrical laminate is composed of a thin wiring board 1, on both the surface and the rear of which circuits are formed, prepregs 2 as bonding material layers, a backup board 3 and an alloy plate 4. As a result, the thickness of the whole laminate required can be compensated for by arranging the backup board 3, the thickness of the wiring board 1 an be inhibited only by the holding of the thickness of the whole laminate while the thickness of the whole laminate is held according to a conventional method, and a base material needed for constituting the wiring board 1, concretely, the number of the prepregs 2, etc., an be deceased. Since a blank having large thermal conductivity as a low thermal expansible alloy is contained in the bonding material layers 2, the heat-dissipating properties of the laminate are improved. Accordingly, the laminate can have the characteristics of a low thermal expansion coefficient and a low dielectric constant.

Title: Fluid pressure release valve
Inventor: CEWERS GOERAN
IPC: F16K17/02
Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To prevent the vibrating operation of a valve (sealing element) by providing a load means energizing the valve in the direction of closing and a drive device operating in such a way that operation force of the load means is reduced in response to the results of detection of changes of a valve position. SOLUTION: When this fluid pressure release valve is used, the pressure release valve remains closed until a force is applied in such a way that a fluid pressure in the valve overcomes a predetermined force, and a sealing element 1 of the pressure release valve is brought into pressure-contact with a sealing ring 4 of an opening 2 due to tensile force of a tensile spring 3. When the valve enters a valve open condition in which the sealing element 1 moves in the direction in which it leaves the opening 2 in this condition, the tensile spring 3 acts to bring the sealing element 1 back to a valve closing position.  However, since a projection 6 acts on a pulling and removal switch 7 when the valve is opened, a rotary drive device 5 is operated, a part with screw thread is elongated by a set portion due to the rotation of the rotary drive device 5, tensile force of the tensile spring 3 is reduced, and a valve open condition is kept.

Title: Data read-out circuit for disk device
Inventor: IKESHITA KOJI
IPC: G11B20/10
Filed: 1990-01-29
Abstract: PURPOSE:To realize the sure removal of a low frequency noise and the reduction of waveform distortion by setting the input resistance of a delay line at a low value according to the hight of the cut frequency of an HPF in the data read- out circuit of a disk device for external storage. CONSTITUTION:In a traditional data read-out circuit, variable resistance 13 is inserted at the input terminal of the delay line 5 so as to constitute combined input resistance together with the input resistance 9. As for an input signal from a magnetic head 1, the low frequency noise is removed surely by setting the cut frequency sufficiently high when it passes through the HPF 3. Besides, since the input resistance of the delay line 5 of a cosine equalization circuit 8 is the combination of the resistances 9 and 13, it becomes low compared with the case of only the resistance 9. As the result, impedance matching between the combined resistance and the delay line 5 is disturbed delicately, and since a reflected wave at the input part of the delay line 5 is adjusted, input signal waveform becomes symmetric, and the waveform distortion is reduced. The value of the resistance 13 is set lower according as the cut frequency of the HPF is higher.
