Title: Waveguide type isolator
Inventor: NAKANISHI FUMITAKE
IPC: G02B6/122
Filed: 1987-02-13
Abstract: PURPOSE:To increase a Faraday rotating angle by using a CdMnTe crystal formed formed on a GaAs substrate as a Faraday rotating material. CONSTITUTION:This isolator is formed via a CdTe buffer layer on the gaAs substrate or InP substrate to be formed with a semiconductor laser and a core and clad consisting of differently composed Cd1-xMnxTe are laminated thereon. For example, a short wavelength laser 2 and the isolator of a waveguide type are formed on the GaAs substrate 1. The isolator is previously formed by epitaxy. The short waveguide laser is then prepd. alongside the same. Said layer is formed of, for example, an AlGaAs mixed crystal system. The isolator is formed by growing the CdTe buffer layer 3 on the GaAs substrate, then forming the clad layer 4, the core layer 5 and the clad layer 6. Since the refractive index of the core layer 5 is required to be made higher, the core layer 5 is made of, for example, Cd0.4Mn0.6Te. The clad layers 4, 6 are formed of Cd0.6Mn0.4Te. The Faraday rotating angle is thereby increased and the isolator having the shorter waveguide suffices.

Title: Recording stylus for record cutting and its production
Inventor: SHIMAMOTO HIROSHI
IPC: G11B3/46
Filed: 1982-03-01
Abstract: PURPOSE:To obtain a recording disc having an expanded recording band and dynamic range by forming notches on relief faces thereby preventing the contact of the relief faces with the modulated grooves of a record in the position where the waveform curvature of the modulated grooves of the record is very small in the case of recording sounds of large amplitude at high frequencies. CONSTITUTION:Notched faces 4 are formed on the relief faces in the horizontal section of a recording stylus to provide a ''relief'' for preventing the contact with the modulated grooves of a record. In this method of production, with a polishing groove 5 of a V-, U- or recessed shape assuming an opening angle alpha to the tip of the recording stylus used and with the mirror face 1 of the recording stylus as a reference plane, the tip of the recording stylus is placed on one side wall of the polishing groove and the recording stylus is moved obliquely along the burnishing face 3 thereof, whereby a relief face 2 is cut, and a notched face 4 is eventually formed. The angle alpha that the face 4 and the face 1 assume is set at 20-30 deg., because if the angle is <20 deg., the strength of the material decreases and if the angle exceeds 30 deg., the effect of preventing the contact with the modulated grooves of the record is lost.

Title: Frequency adjustment device for oscillation circuit
Inventor: OSAWA HIROSHI
IPC: G06F1/04
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To easily obtain the oscillated frequency expected in an RC oscillation circuit. SOLUTION: After a 1-chip microcomputer is reset and released, an instruction of a 2nd program area of a ROM 11 is decoded, switch circuits 9-1 to 9-n are switched, in response to correction data of a nonvolatile memory 10. An RC constant is adjusted in connecting a resistor 4, and any of oscillation adjustment resistors 8-1 to 8-n in series selectively. The current oscillating frequency of an RC oscillation circuit differs from an expected oscillation frequency, then correction data in response to the difference between both the oscillating frequencies are replaced with the correction data in the nonvolatile memory 10, and the operation above is repeated. When the adjustment of the oscillated frequency of the RC oscillation circuit is finished, the processing jumps to a heading address of a 1st program area of the ROM 11, and the execution transits to the normal operation.
