Abstract: PURPOSE:To obtain an optical disk that is a proper circle, and having a center hole with small eccentricity, by molding a substrate and a metal laminated disk member separately, joining both members over entire main planes, and fixing them tentatively while a first bonding agent is hardened. CONSTITUTION:A guide groove spiral 18 is formed concentrically for a large circular center hole on one main plane of a transparent circular substrate 7 having a large circular center hole 8, and the metal laminated disk member 1 having a small center hole 3, the inside diameter of which is smaller than that of the large circular center hole 8, and having an outside diameter larger than the inside diameter of the large circular center hole 8, is formed. Next, the small center hole 4 of the metal laminated disk member 1 is positioned concentrically for the circular substrate 7, and the metal laminated disk member 1 is placed on one main plane of the circular substrate 7 through a first bonding agent 9. Next, after a second bonding agent 10 is arranged in the neighborhood of the surface of the circular substrate 7 positioned at the edge side plane of the metal laminated disk member 1, the second bonding agent 10 is hardened before the hardening of the first bonding agent 9, and thereby, the metal laminated disk member 1 and the circular substrate 7 are fixed tentatively. In this way, it is possible to form the optical disk having the center hole formed in an accurate proper circular shape, and with small eccentricity.

Title: Time division multiplex travelling body communication equipment
Inventor: TSUZUKI AKIO
IPC: H04B1/40
Filed: 1989-09-21
Abstract: PURPOSE:To keep the antenna to the best matching state at all times even when the environment around the antenna is changed by utilizing a time other than a time slot so as to match the antenna based on the result of measurement with a standing wave ratio measuring circuit in advance and disconnecting the standing wave ratio measuring circuit at the time slot to be sent. CONSTITUTION:When a changeover switch 152-b to measure a transmission standing wave ration is thrown to the position of (b), the signal is applied to an SWR measuring device 153-2 to measure the transmission standing wave ratio. A DC voltage varying with a prescribed step is applied to the SWR measuring device 153-2 (153-1) with a command from a control section 140 and the standing wave ratio SWR varies with a change in the resonance frequency f0 of an antenna 102. Thus, the optimum matching is taken for the antenna 102 at all times by varying the resonance frequency f0 and stable transmission is always attained independently of the environmental change around a mobile radio equipment 100.

Title: High speed rotating arc welding method
Inventor: SUGITANI YUJI
IPC: B23K9/00
Filed: 1987-10-01
Abstract: PURPOSE:To improve accuracy of weld bead width aud height by calculating an integral value of rotating arc voltages or welding currents and controlling an arc rotating diameter and controlling the deposited metal quantity at the same time. CONSTITUTION:The rotating arc voltages or welding values are integrated in the right and left directions to the welding proceeding direction. The sum S of each integral values SL and SR is inputted to one input end of a differential amplifier 18 and a value S1 corresponding to an initial value of SL+SR is stored and maintained in a storage device 19. A value of SL+SR-S1 is calculated by the amplifier 18 and a motor 15 is driven to control the arc rotating diameter D by a rotating diameter controller 20 so that said value is diminished to zero. Further, the deposited metal quantity is controlled by controllers 24, 26 and 28 by comparing the diameter D with a reference rotating diameter D0. By this method, since the rotating diameter D and the deposited metal quantity can be controlled at the same time, the accuracy of the weld bead width and height is improved.

Title: Optical exchange
Inventor: FUJIWARA MASAHIKO
IPC: H04Q11/02
Filed: 1986-10-15
Abstract: PURPOSE:To effectively utilize the frequency band area of a light and to attain the enlargement of a scale by introducing an optical heterodyne and an optical homodyne detector into the photoelectric conversion type variable branching filter part of a wave-length dividing type optical exchange. CONSTITUTION:The photoelectric conversion type variable branching filter 17 in the optical exchange 12 consists of an optical branch 13 and the heterodyne detectors 14a-14d. At first, a signal divided into four parts by a waveguide type optical branch 13 is made incident upon the optical heterodyne detectors 14a-14d respectively. An optical signal 101 which is the output of the optical branch 13 is made incident upon the first terminal 103 or an optical mixer 102, and is mixed together with a locally oscillated light 106 which is incident upon the second terminal 104, and is made outgoing to third and fourth terminals. The mixed light made outgoing to the third terminal 105 is made incident upon an optical detector 107, and is converted into an intermediate frequency signal (electric signal) 108. The intermediate frequency signal 108 is inputted to a demodulation circuit 110 after being amplified by an amplifier 109, and here a received signal 111 is demodulated. Thus, because the optical signal to be exchanged can be made into the optical wave-length multiple (WDM) signal of an extra high density, the optical exchange of a large scale can be realized.
