Title: Combined machine for punching and laser beam
Inventor: MIYAMA HIDETOSHI
IPC: B23K26/00
Filed: 1989-03-15
Abstract: PURPOSE:To prevent the vibration of optical parts of laser beam machining to make compact a work positioning device and to facilitate its control by supporting a laser beam machining head under noncontact state with a press main body by cantilever supporting via a laser beam optical path tube from a laser beam oscillator mounting base. CONSTITUTION:The laser beam oscillator mounting base 55 on which the laser beam oscillator 57 is mounted is provided at a distance from the press main body 7 for punching work. At the same time, the laser beam machining head 67 is supported under noncontact state with the press main body 6 by cantilever supporting via the laser beam optical path tube 59 from the laser beam oscillator mounting base 55. As a result, since the vibration generated at the time of punching work is not transmitted to the laser beam machining head 67 and the laser beam oscillator 57, the optical parts of laser beam machining are prevented from being damaged and laser beam machining with high accuracy is performed. In addition, since the laser beam center 69 is offset in the direction of the Y axis from the punching center 33, the work positioning device is made compact and its control is facilitated.

Title: Pseudo error pulse inserting circuit
Inventor: SUEMITSU TAKAHIRO
IPC: H04L1/24
Filed: 1981-04-21
Abstract: PURPOSE:To achieve adjustment and test only with a transmission and reception data processing section, by inserting a pseudo random pulse having no correlation to data. CONSTITUTION:After a clock signal is frequency-divided at a frequency divider 2, a pseudo random pattern generator 3 is driven. A pseudo random pattern for input data series is picked up from outputs T0-Tn-1 of each stage of an N stage pseudo random pattern generator 3. The pseudo random pattern is inserted to a dta train via an exclusive logical sum 5. As a result, the polarity of data of the same time slot as the pseudo error pulse is inverted. This inverted part becomes the data error. The data error rate is determined by adjusting the frequency dividing ratio of the frequency divider 2.

IPC: H04N1/32
Filed: 1979-05-16
Abstract: PURPOSE:To secure an easy detection for the interruption and call signals sent from the receivier under transmission, by memorizing the gain control voltage at the reception of the signal from the receiver into the gain control voltage memory and then comparing this memorized voltage with the control voltage under transmission. CONSTITUTION:The gain control voltage at the time of transmission of the signal sent from the receiver is memorized in digital memory part 3 of gain control voltage memory circuit 1. And the comparison is given at comparator 9 between the potential memorized in part 3 and the potential at position P decided by reverse amplifier 5 which supplies the input to the AGC circuit under transmission, comparator 6, switch 7 and others. Based on the comparison result at comparator 9, the control is given to switching of analog switch 11. Thus the potential at position P is controlled down to the potential which is memorized in part 3. Then the sensitivity control is given to the AGC circuit even under transmission so that the interruption signal sent from the receiver can be detected completely. Thus the detection can be facilitated for the interruption and call signals which have the faint output of the signal.

IPC: G11B23/087
Filed: 1984-03-28
Abstract: PURPOSE:To always attain the stable tape driving by forming a position control hole of a cassette on the same axis as a tape guide position in order to avoid the tilt of a tape guide as well as the deformation of the tape guide despite its loading of a long period of time. CONSTITUTION:A cylindrical tape guide 7 is fitted to a boss 9 of an upper case 8, and a cassette position control hole 10 is formed to a lower case 11 on the same axis as the guide 7. The guide 7 is held between both cases 8 and 11. When a cassette is positioned, a positioning pin 12 is fitted to the hole 10. Thus both the guide 7 and the hole 10 are set on the same axis. This eliminates the conventional tilt of the guide 7 and also prevents the deformation of the guide 7 despite its loading for a long period of time. Thus the stable driving is always secured for a tape.

Title: Time constant circuit
IPC: H03G7/08
Filed: 1992-03-18
Abstract: PURPOSE:To reduce tertiary higher harmonic distortion in an output signal by providing a buffer amplifying circuit for outputting a level detecting signal and driving a time constant setting circuit, and also, allowing an input signal of the time constant setting circuit to be subjected to negative feedback to an input side. CONSTITUTION:A level detecting signal D being a full-wave rectifying current being proportional to a level of an input signal from a level detecting circuit 4 is impressed to a positive input of an operational amplifier A61 of a buffer amplifier 61. A (b) point of an emitter side of a transistor Q61 is connected to an inversion input of the operational amplifier A61, therefore, a negative feedback circuit of the operational amplifier A61 is constituted. Accordingly, by this negative feedback operation, a variation portion of a base-emitter voltage caused by a variation of an emitter current of the transistor Q61 at the time of charging of a capacitor C61 is absorbed. As a result, a condition that a peak position of a voltage of an (a) point and a peak position of a voltage of the (b) point are always equal to each other is held, therefore, a faithful level control is executed to the level of the input signal.
