IPC: C23C4/18
Filed: 1978-07-28
Abstract: PURPOSE:To enhance the adherence between a sprayed layer and a base metal by forming the layer on the metal surface with metal powder and by irradiating a high energy density heat source to alloy the layer and the base metal by heating. CONSTITUTION:Moving body 4 provided with torch 2 for spraying and torch 3 for alloying is set above base metal 1 to be sprayed. Driving part 5 of body 4 is moved forward along guide rod 6. At the same time, metal powder is sprayed from plasma jet torch 2 to form sprayed metal layer 7, which is then irradiation-heated with high energy density heat source torch 3 such as plasma, electron beam or laser beam torch set leaving a fixed space. Sprayed metal 7 is alloyed with base metal 1, thus remarkably enhancing the adherence between them.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a optical scanner which can obtain a stable beam spot free of spot size variation due to the influence of diffraction in both a horizontal and a vertical scanning direction. SOLUTION: The optical scanner is equipped with a light source 1, shaping optical systems 2 and 3 which converts the light beam (b) from the light source 1 into a shaped light beam having specific characteristics, a deflector 4 which deflects the shaped light beam, and a scanning optical system which forms a beam spot of the light beam deflected by the deflector 4 to scan a scanned surface 17. In this case, two apertures 18, 19 are formed in the optical path extending from the light source 1 to the deflector 4 at the different positions; and one aperture 18 limits the diameter of the light beam only in the vertical scanning direction and the other aperture 19 limits the diameter only in the horizontal direction, so that the optical system behind at least one aperture 18 forms an image at a nearly infinite distance from the scanned surface.

Title: Head drive device of thermal printer
Inventor: KURAFUJI HIROSHI
IPC: B41J25/316
Filed: 1989-04-12
Abstract: PURPOSE:To obtain a low-cost, compact head drive device with excellent performance by rotating the support shaft of a carriage with a gear with no teeth at the upper half and a gear with no teeth at the lower half at a specified angle, causing a thermal head to come in contact with and separate from a platen and performing the shuttle travel of the carriage and the action of the thermal head to come in contact with and separate from the platen using a single motor. CONSTITUTION:During the reversed rotation of a drive motor 10, a carriage is caused to freely run by the engagement claw 16a' of a lower gear 16a on a drive wheel from one end to the other of a play groove 16b' for an upper gear 16b. During this period, the upper gear 16b of a carriage feed wheel 16 stops and a gear mechanism for carriage shuttle travel which is engaged with the former does not work. An upper or a lower idle gear 22a, 22b engages with the corresponding gear with no teeth at the upper half or the corresponding gear with no teeth at the lower half 24a, 24b through an idle gear for carriage drive 22c which is constantly engaged with the lower gear 16a during the free-running of the engagement claw 16a. The support shaft of a carriage drive mechanism rotates through a pulley 25 during the period when the teeth part of the gear is driven by engagement with the idle gear. A head loading mechanism functions only when a drive motor is reversed and thus the action of the thermal head to come in contact with and separate from the platen takes place due to the rotating power of a single motor.

Title: Multiplex transmission system of signal
Inventor: SUZUKI YOSHIHARU
IPC: H04Q9/00
Filed: 1979-07-20
Abstract: PURPOSE:To increase the reliability of the system by securing such state under which the specified terminal unit transmits the return signal by the control signal sent from the master unit and regardless of the operation switch and thus giving a periodical function check to the terminal unit. CONSTITUTION:The signals are transmitted and received in the time-division cyclic multiplex transmission method between the master unit and plural numbers of terminal units, and no return signal is usually transmitted from the terminal. In such system, change-over bit A is given to part of control signal SC sent from the master unit in terms of existence of the return signal, and the rest of the control signal is defined as control data B. Terminalunit 2 extracts bit A by serial-parallel converter 5 to apply it to OR gate G2. At the same time, switch gate signal SWG is supplied to gate G2 from signal process part 6 to be turned to the H level if either one of operation switches 7 is pushed. Then bit A is set at the H level for the control signal sent from the master unit. Thus return signal RET can be transmitted from terminal 2 regardless of switch 7 to lealize a periodical function check for the terminal. As a result, the reliability can be increased for the system.

Abstract: PURPOSE: To reduce power consumption of a stepping motor by predicting the load state of the stepping motor being employed for driving a lens and feeding the stepping motor with a drive voltage (drive current) corresponding to that state. CONSTITUTION: A circuit 13 provides an adder 14 with a control signal for a motor 4 moving a focus lens 2. A zoom instruction is fed externally to a circuit 12 which provides the adder 14 with a control signal for a motor 3 moving a zoom lens 1.

Based on the received signal, the circuits 16, 17 read out a sine wave data having an appropriate amplitude which is fed to motor drivers 18, 19 for driving the motors 3, 4. Since the drive voltage (current) is optimized, power consumption of the motor is suppressed.
