Patent JP-H01295043-A (JP)
Title: Hydraulic buffer
Inventor: ONO SOICHI
IPC: F16F9/48
Filed: 1988-05-20
Abstract: PURPOSE:To surely generate a damping force which varies according to the load by installing an annular member which divides the second chamber into two small chambers in cooperation of the second piston, oppositely to the second piston in a cylinder, when the stroke in the compression direction of a piston rod becomes a prescribed magnitude. CONSTITUTION:Since the stroke of a piston rod 5 is relatively small when the load is ordinary, the second piston 27 is separated from an annular member 36. If, in this state, an impact load is applied, and a piston rod 5 applies a stroke in the compression or extension/compression direction, the first damping valve 26 installed onto the first piston 2 generates a damping force. Since, at this time, the second chamber 4 forms a large chamber, the second damping valve 29 does not operate, and the generated damping force is due to the valve 26, and is relatively small. When the load increases, and the stroke of the rod 5 exceeds a prescribed magnitude, the piston 27 is fitted into the inner space of the annular member 36, and the chamber 4 is divided into two small chambers 4a and 4b. At this time, the damping valves 26 and 29 are operated.

Title: Facsimile
Inventor: YAMAJI SATORU
IPC: H04N1/00
Filed: 1992-05-15
Abstract: PURPOSE:To provide the facsimile capable of transmitting originals with the simple operation to reduce the burden of an operator. CONSTITUTION:When a business card is inserted to a CCD reader 18, a facsimile 11 takes out the information required for the facsimile communication from the information displayed on the business card by means of a character recognition processing circuit 22, which is coded to be stored in a memory 21. Based on the stored data, the automatic originating call to the opposite party and the automatic preparation for sending messages are executed. Thus, the operations before the facsimile communication, such as the preparation for sending messages to the opposite party and the dial input of the facsimile numbers of the opposite party are made unnecessary.

Title: Magneto-optical disk
Inventor: NAKAJIMA YOSHIRO
IPC: G11B11/105
Filed: 1987-05-22
Abstract: PURPOSE:To enable recording of high-frequency signals and to contrive miniaturization of a device by providing a magnetic material layer between a disk substrate and thin film magnetic recording medium. CONSTITUTION:The transparent magnetic material layer 8 as the magnetic material layer is provided between the disk substrate 2 and the thin film magnetic recording medium 1. The magnetic lines of force emitted from a magnetic head 3 for writing perpendicularly penetrate the recording medium 1 and concentrically pass the inside of the transparent magnetic material layer 8 without spreading much to a free space as the freshly provided transparent magnetic material layer 8 exists when a writing operation is carried out by using the magneto-optic disk 10 constituted is such a manner. These magnetic lines of force enter the opposite pole of an electromagnet 3. A short return magnetic path is thereby formed, by which the efficiency is extremely enhanced. In addition, the smaller electromagnet is necessitated and, therefore, the device is miniaturized.

Title: Method for matching voice pattern
Inventor: FUJIMOTO JUNICHIRO
IPC: G10L15/06
Filed: 1990-05-14
Abstract: PURPOSE:To execute correct collation by converting a specific part into a determined length, comparing the pattern of a part removed from the vicinity of an end part up to the end and its residual pattern with reference patterns and defining a result having higher similarity as a similar pattern. CONSTITUTION:The pattern of an obtained feature variable is expanded/contracted to the determined length, the expanded/contracted pattern is stored and registered in a reference pattern storing memory 6, and at the time of ending the registration, a switch 5 is turned to the recognition side to recognize the pattern. When there is a part whose power is lower than a fixed value, whether a frequency components are concentrated into a high range or not and whether the range is the head or the end of the pattern are checked respectively by comparing parts 13, 15, the whole length of the pattern is expanded/contracted by an expanding/contracting part 16 and the processed data are stored in a memory 17. A collating part 7 finds out the similarity or error of the obtained pattern with/from respective reference patterns and a maximum similarity detecting part 8 detects the reference pattern representing the maximum similarity and outputs a code or the like expressing the detected reference pattern as a recognized result. Thus, patterns can be correctly collated without expanding/contracting them at the time of collation.

Patent JP-S62281524-A (JP)
Title: Fm transmitter
Inventor: UMEMOTO KATSUHIKO
IPC: H04B1/04
Filed: 1986-05-29
Abstract: PURPOSE:To eliminate unpleasant stereo demodulation noise by avoiding the modulation of a pilot signal when the music signal of a compact disk such as stop, pause or skip mode is not reproduced so as to allow a receiver to receive an FM radio wave monaurally. CONSTITUTION:In not reproducing the music signal of the compact disk such as the stop, pause or skip mode, since a 19kHz pilot signal being the output of a divider 5 is not injected to an FM oscillator 6, no pilot signal is modulated. Thus, in receiving a radio wave from the FM transmitter by a receiver, its demodulator recieves the wave in a monaural state. In reproducing the compact disk at the mode other than the stop, pause or the skip mode, the level of an output terminal 1a goes to a high level and a transistor 9 is conductive, then the 19kHz pilot signal is injected to the FM oscillator 6 and modulated together with the music signal. Thus, in receiving the radio wave of the FM transmitter by the receiver in such case, the demodulator applies the reception/ reproduction in the stereo mode.

Title: Auxiliary reflection mirror moving mechanism for telescope
Inventor: NAKAMURA KATSUSHIGE
IPC: G02B23/02
Filed: 1990-05-16
Abstract: PURPOSE:To adjust the inclination of an auxiliary reflection mirror with a high precision by storing a supporting shaft, to which the auxiliary reflection mirror is attached, in a housing so that it can be freely taken into and out from the housing and supporting the housing so that its inclination to the optical axis can be freely adjusted. CONSTITUTION:It is necessary to attach straightly an auxiliary reflection mirror 18 to a supporting shaft 16. The method for inspecting the attachment is shown in figure. The auxiliary reflection mirror 18 is turned around its axis B and is irradiated with the laser light L from the external. If the reflected laser light L is fixed at the point P of a sensor S, the auxiliary mirror 18 is straightly attached to the supporting shaft 16. The supporting shaft 16 to which the auxiliary reflection mirror 18 is straightly attached is stored in a housing 6. Next, it is checked whether the axis B of the supporting shaft 16 coincides with an optical axis A of a telescope or not. If the axis B is inclined, the inclination of the whole of the housing 6 is changed by adjustment between a pin 13 in the front end of a supporting plate 8 and a long hole 14 of a bracket 11 to correct this inclination of the axis B. Thus, this mechanism is characterized by adjustment of inclination of the whole of the housing 6.

IPC: H01L23/62
Filed: 1987-05-21
Abstract: PURPOSE:To provide a low limiting voltage against an overvoltage by a method wherein a semiconductor layer for transistor use is formed inside a semiconductor region and a collector layer and a base layer whose conductivity type is opposite to that of the collector layer are connected in series so that a reverse- direction voltage can be impressed. CONSTITUTION:A semiconductor layer for transistor use is formed inside a semiconductor region 13 which is separated electrically from a substrate 10. A collector layer 21 and a base layer 22 whose conductivity type is opposite to that of the collector layer at least in the semiconductor layer for transistor use are connected in series between a wiring part 50 to be protected against an overvoltage and an operating reference potential point of a semiconductor circuit device so that a reverse-direction voltage can be impressed on a semiconductor junction between the layers. While the reverse-direction voltage is impressed between the collector layer and the base layer, the overvoltage is limited by their breakdown strength or breakdown voltage. By this setup, a protective device can have a limiting voltage which is lower than a conventional limiting voltage and which is best fitted to a characteristic of a circuit element.
