Abstract: PROBLEM TO BE SOLVED: To provide a wire working device to facilitate maintenance of levelness. SOLUTION: A clamp frame 3 having a clamp 4 to hold a cable 100 is provided on an outer part frame 1 so as to be able to axially revolve a shaft center of the cable 100 as its center, and the clamp frame 3 is devised to axially revolve by a hydraulic cylinder.

Title: Digital circuit
Inventor: TATENO MINORU
IPC: H03K19/08
Filed: 1988-02-03
Abstract: PURPOSE:To reduce the current consumption of the digital circuit without losing high speed performance by detecting a specific logic level of a logic output level so as to control the circuit in an idling state thereby keeping its output to a specific logic level. CONSTITUTION:A level detection means 40 outputs an H level as a detection output VCO when an output OUT of a digital circuit 10 goes to L (specific logic level increasing DC current consumption). A control circuit 60 turns off FETs Mp1, Mp3 of level conversion circuits 13, 14 in this case forcibly respectively. Thus, DC currents I1, I2 flowing respectively to FETs Mp1-Mn1 and Mp3-Mn3 are cut off. Thus, the circuit 10 reaches the idling state not consuming the DC current. TRs Q1, Q2 of the output section 11 are both turned off and the output OUT is in floating state, but the logic level in this case is kept to L level by a resistor R1 of a holding circuit 60 because the level is drawn toward the negative power supply potential VEE, that is, the L level.

Title: Semiconductor device
Inventor: FUKUCHI JUN
IPC: H01L21/822
Filed: 1985-02-12
Abstract: PURPOSE:To prevent interlayer leaking in a double-layer structure at a design rule of 3mum or less, by specifying the angle of the end part of a first-gate conducting film and the angle of the end part of a second-gate conducting film. CONSTITUTION:An angle theta1 (60 deg. or less) is provided at a first-gate conducting film 2. Owing to the angle at the end part, the amount of remaining poly silicon is less when a second gate 4 is formed. The poly silicon is sufficiently removed by oxidation in the succeeding process. A highly accurate pattern is required for the end pat of the second gate 4 in comparison with the first gate. Therefore a steep angle of 60-90 deg. is required for an angle theta2 for the end part when a design rule of less than 3mum is applied. The overhung state of more than 90 deg. is not desirable because there are troubles in flatness and the remaining amount of poly silicon.

Title: Impact dot head
Inventor: NAKAJIMA SUSUMU
IPC: B41J29/08
Filed: 1992-02-12
Abstract: PURPOSE:To ensure the response of a printing wire excellent in durability and damping characteristics and imparting printing quality free from temp. characteristics by forming the damper of an impact dot head by laminating a plurality of thin metal plates. CONSTITUTION:A damper 1 is formed by laminating thin metal plates composed of tool steel or stainless steel. After a printing wire 5 impinges against a plate 12, the armature 2 is returned by the repulsive force of the platen 12 and the force of a return spring 3 and revolved around a fulcrum 8 in the direction shown by an arrow to collide with the damper 1. Since the force generated by this collision has not only the component in the direction vertical to the damper 1 but also the component parallel to the damper 1, the moment the armature 2 collides with the damper 1 the thin laminated metal plates constituting the damper 1 mutually generate fine shift (a). Herein, since the kinetic energy possessed by the armature 2 is consumed by the friction force between the metal plates and the shearing force generated in the oil film between the metal plates to be changed to heat, the rebounding of the armature is suppressed low and the armature 2 rapidly returns to a standby position.

Abstract: PURPOSE:To convey documents to a specified position without dispersion of document stop positions by detecting a first specified conveyance quantity at a point of time when a tip of the document is detected in document inversion, and then stopping operation of a conveyor belt mechanism when a second specified conveyance quantity is detected. CONSTITUTION:When a document detector SW8 detects a tip of a document conveyed to a document inversion passage 142 by a document inversion means 128 at the time of document inversion, it transmits a detection signal thereof to a control means.

Filed: 1982-02-19
Abstract: PURPOSE:To control the potential at the medium tap point of a channel selecting volume resistance in a medium region having the largest shift, by adding a compensating volume resistance in parallel to the channel selecting volume resistance. CONSTITUTION:A mobile bar 17 of a compensating volume resistance 13 is controlled at the center position, i.e., at a current i=0. Thus the characteristics (a) are first obtained for an electronic tuner circuit 4 using a standard variable capacity diode. At the same time, the characteristics (b) are obtained when an actual variable capacity diode having variance is used. For the characteristics (a), a channel M is received when a mobile bar 3 has its 1/3 position. In this case, the tuning voltage is 10V. For the characteristics (b), the tuning voltage is 7.2V for reception of the channel M. Then a mobile bar 17 of the resistance 13 is changed to 7.2V from 10V while the bar 3 of a channel selecting volume resistance 2 is fixed at 1/3.

A pressing position of this projection 10 is adjusted with a motor to be driven by a control unit 16 via a wire. When an engine is in a slow speed, it pressed the member 6a so as to make the suction passage narrower but at the time of a high speed, it retracts the member 6a so as to make it wider. Both ends in the longitudinal direction of the member 6a sticks fast to an inner surface of the suction passage, and since the suction passage is smoothly deformed, there is no turbulent flow at all.
