Title: Magnetic head
Inventor: KOSEKI HIDEO
IPC: G11B5/127
Filed: 1986-10-29
Abstract: PURPOSE:To facilitate production of a magnetic head consisting of a thin magnetic metallic film as it main core and to improve the yield thereof by using mica ceramics as a substrate material. CONSTITUTION:This magnetic head is constructed by sandwiching both faces of the thin magnetic metallic film 1 which is the main core by the mica ceramics 2. A thin film of an amorphous alloy or 'SENDUST(R)' is used as the film 1. In this embodiment, the thin amorphous alloy film 1 essentially consisting of Co is formed by sputtering on both faces of mica ceramics substrates 2. Since the mica ceramics are used as the substrates for vapor deposition of the film 1 which is the main core and a holding material thereof, the precise cutting and working are facilitated by the good workability thereof. Said ceramics have the coefft. of thermal expansion approximate to the coefft. of thermal expansion of the amorphous alloy and thin 'SENDUST(R)' film and, therefore, the deterioration in the characteristic by the influence of magnetorestriction, etc., is decreased and the good magnetic characteristic are exhibited.

IPC: H04W64/00
Filed: 1992-09-01
Abstract: PURPOSE: To exactly perform position measurement for a moving object by receiving coded high speed information with a moving object other than the first moving object and reconstructing the initial high speed information using correlation with a time division code and demodulation. CONSTITUTION: A transmitter 10 receives high speed information which each of moving objects 1 to 3 should sends and after modulating and coding with time division code, it generates coded high speed information F1. Receivers 23 and 33, after receiving this information F1, reconstruct the initial high speed information using the correlation of the demodulation and time division code. A responding device 24, after receiving low speed information to transmit, generates coded low speed information F2. After receiving this information F2, reconstructing the initial low speed information and comparing the phase delay of the time division code corresponding to the low speed information with the time division code for coding the high speed information, position measuring receivers 15 and 35 produce distance information.  The receivers 15 and 35 also measure the position of various moving objects using triangulation based on the distance information.

Title: Optical transmitter
Inventor: SUNAGA YOSHINORI
IPC: H04B10/58
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To shorten the rise/fall time of an optical output waveform for an optical transmitter containing a current switch circuit by connecting a circuit having a resistor connected in series to an inductor in parallel to a light emit ting element. SOLUTION: Receiving a transmitting signal, a controller circuit 101 actuates a current switch 102 to perform the ON/OFF control of the collector current of a transistor 102b. Based on this control, a light emitting diode 104 blinks and the light that undergone the light intensity modulation and outputted from the diode 104 is transmitted in an optical fiber. A circuit where an inductor 105 and a resistor 106 are connected together in series is connected in parallel to the diode 104. In such a constitution, a large current flows for an instant at the rise of the diode 104. Thus the rise delay of an optical output waveform is corrected. At the same time, a reverse current flows to the diode 104 for an instant due to the undershooting at the rise of the current. Then the electric charge is discharged in the diode 104, and the rise/fall time is shortened for the optical output waveform.
