Abstract: PURPOSE: To provide a substrate structure reducing the capacitance between the collector and the substrate for a transistor. CONSTITUTION: A substrate structure 71 is provided with a substrate 21, an insulator 25 having a window, a feed through layer 29 formed in the window, and a sub-collector layer 31. Next, a collector 77, a base 79 and an emitter 81 are formed thereon. The narrower the contact area between the substrate 71 and the subcollector layer 31, the less the capacitance between the substrate and the collector. The contact area between the substrate and the feed through layer 29 is specified by the size of the window. It is preferable that the window size is as small as possible. In an embodiment, the window size is almost similar to that of an active region of the transistor.

Title: Fluid pressure vibration damper
Inventor: STEFAN LEOPOLD JOSEPH DEFELME
IPC: F16F9/348
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a vibration damper with a valve structure which minimizes the transmission of noise and vibration. SOLUTION: This damper includes a pressure cylinder 62, a piston 64, and a valve structure for noise reduction, which isolates the cavitation area so as to keep it away from the metal structure forming the valve structure. This construction forms a boundary in the vicinity of the valve outlet, enlarges the operating fluid area adjacent to the outlet of the valve structure, where a burst takes place, and has a sharp rebound-to-land edge angle. Further, this construction eliminates the skirt section at the periphery of the piston 64 and avoids the piston 64 from contacting the pressure cylinder 62. A support piston contacts the inner wall of the pressure cylinder 62.  The isolation of a cavitation area 104 from these pistons and the metal surfaces of the valve structure dramatically reduces the transmission of noise and vibration caused by a burst in the operating fluid and transmitted through a vibration damper.

Title: Switching system
Inventor: OTSUKI KANEICHI
Filed: 1987-11-26
Abstract: PURPOSE:To reduce the buffer memory capacity by using a distribution section so as to apply parallel conversion to each of serial input and storing it in a register corresponding to the output via a buffer memory. CONSTITUTION:Serial inputs 21-2n are subject to parallel conversion in the unit of several bytes by S/P converters 31-3n. Then packet resisters 511-51n 5n1-5nm having FiFo function corresponding to the output store the result via packet buffers 41-4n having a common FiFo function. Then a packet is sent to output parallel buses 61-6n so as not to cause any corrosion in a proper order from a packet register corresponding to the same output. Thus, the capacity of the buffer or register by output is enough to be small and the switching system with less memory capacity is obtained.

Title: Storage device
Inventor: SENGOKU SHINJI
IPC: G11B20/18
Filed: 1985-12-27
Abstract: PURPOSE:To detect previously the possibility of an erasure accident of stored information being slightly high by providing a detecting circuit which inputs an error signal from an error detecting circuit for detecting an error of information reproduced from a disk and detects the extent of the error exceeding a specific value. CONSTITUTION:When a head 6 and the disk 3 are not damaged very much, reproduced information has no error or a small error, so the error detecting circuit 12 outputs no pulse signal or a small number of pulses. A counting circuit 16, therefore, does not count or has a small counted value, the counting circuit 16 outputs no detection signal. When the head 6 or disk 3 begins to damage greatly, information reproduced from the disk 3 through the head 6 and a recording and reproducing circuit 11 have an error frequency, so many output pulses are outputted by the error detecting circuit 12. The counted value of the counting circuit 16 exceeds a specific value within a time predetermined by a timer 15, so the counting circuit 16 outputs a detection signal.

Title: Focus controller
Inventor: SHIBANO MASAYUKI
IPC: G02B7/28
Filed: 1985-12-27
Abstract: PURPOSE:To attain highly accurate focus control by repeating holding and releasing of a focus error signal by a holding circuit according to specified level of a tracking error signal. CONSTITUTION:When a pickup 20 is moved, a tracking error signal 15 becomes as shown in the figure. At this time, a groove crossing detecting circuit 22 outputs a signal 23 that indicates that the extent is crossed, and a signal 24 that indicates that the tracking error signal is zero. A normal close contact switch 17, a normal open contact switch 25 and a holding circuit 26 operate responding to signals 23, 24. The pickup 20 moves to other recording tracks or detects flaws etc. on the disk surface. When a tracking error signal exceeds the limits of +V, -V, the signal 23 is outputted from the groove crossing detecting circuit 22, and the switch 25 becomes the closed state, and the switch 17 becomes the open state. Accordingly, a focus error signal held by the holding circuit 26 is inputted as a focus error signal to a phase compensation circuit 18 and a driving circuit 19 of the pickup.
