Title: Control circuit for magnetic disk device
Inventor: MACHIDA TAKASHI
IPC: G11B20/18
Filed: 1991-02-15
Abstract: PURPOSE:To improve the reliability of a write operation and further to shorten rotation waiting time. CONSTITUTION:A servo pulse detector 1 generates a pulse signal S2 from a signal S1 from a servo disk medium. A phase synchronizing oscillator 2 generates a clock signal S3 synchronizing the phase to that of this pulse signal S2. A loop counter 4 counts the number of these clocks and outputs an index pulse signal S7 for each count value corresponding to the one rotation of a magnetic disk. Even when noise is mixed in the signal S1, the signal S3 is hardly affected by the noise and therefore, the signal S7 is stable so as to improve the reliability of the write operation based on this signal. When switching a cylinder to be accessed, a count value setter 8 can adjust timing for the counter 4 to output the signal S7 and therefore, the rotation waiting time can be shortened. A timing error detector 5 and an index miss detector 6 detect non-coincidence between the timing of an index pattern contained in the signal S2 and the timing of the signal S7 and at that time, an index error processor 7 outputs a signal S12 for write inhibition.

Title: Interference eliminating system for time-division multiplex communication
Inventor: HIROKAWA OSAMU
IPC: H04W72/08
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To confirm a reception error due to the interference and to reduce the power consumption of a mobile terminal device by expanding reception level intensity measurement to over slots only when the reception error is generated and eliminating asynchronous interference. SOLUTION: For example, a PS (mobile terminal device) 2 of a TDMA/TDD radio communication system has a radio communication with a master device 1 by using, for example, a slot 2 and a reception error is generated once owing to the interference from a slot 1 or 3. In this case, the measurement of reception level intensity which is carried out in the timing level of a reception slot center for reception level intensity display is expanded by winding the width of an RX-ON signal. Consequently, the occurrence of the reception error in the presence of an asynchronous interference wave approaching even the adjacent slots 1 and 3 can be detected and the channel slots can smoothly be switched.

Title: Constant voltage diode
Inventor: YOSHIKAWA KIMIMARO
IPC: H01L29/861
Filed: 1979-04-10
Abstract: PURPOSE:To obtain a constant voltage diode capable of taking a given value, by providing electrical connection between base and collector of npn-transistor. CONSTITUTION:n-Epitaxial layer 12 on p-type Si substrate 13 is separated by p- layer 11 to make p-type base 14, n<+>-type emitter 15 and n<+>-type collector take- out layer 16. The base 14 and the collector take-out layer 16 are connected with each other to provide a catahode, and the emitter 15 is to become an anode. Now, if width of base of transistor is smaller than spreading of void layer due to voltage impressed in the opposite direction, punch through occurs at voltage smaller than avalanche breakdown voltage Vz. And therefore, it is possible to control punch through voltage by controlling width of base, to control the base width by controlling npn-transistor's emitter grounding current amplification factor hFE and to lower the punch through voltage by increasing hFE. It is possible, in this manner, to obtain a constant voltage diode capable of taking a given value simply by controlling hFE.
