Title: Printing head cleaning device in printer
Inventor: AOKI RYUJI
IPC: B41J2/165
Filed: 1995-02-08
Abstract: PURPOSE: To clean a printing head for a long period of time by a method wherein a wiper is formed so as to be capable of being moved orthogonally to the moving direction of a carriage while the wiper is pushed against and separated from the printing head while being operated in conjunction with the reciprocating motion of the carriage. CONSTITUTION: When a carriage 4 moves forward and approaches one end of a moving route while the engaging projection 19 of the carriage 4 is collided against the other end 15b of an arm 15, the arm 15 is pivoted clockwise to lift up the end 15a of the arm 15, a wiper holder 7 is elevated through a pin 18 and the wiper 8 is pushed against a printing head 5a to clean the same through the elastic deformation of the wiper 8. The engaging projection 19 passes the upper part of the other end 15a of the arm 15 whereby the arm 15 is returned to the initial position thereof.  When the carriage 4 has arrived at one end of the moving route thereof and is converted to return while the engaging projection 19 is collided against the other end 15b of the arm 15, the arm 15 is pivoted counterclockwise and the end unit 15a is lifted up, a wiper holder 7 descends through the pin 18 and the wiper 8 is separated from the printing head 5a.

Title: Control system of elevator
Inventor: OGAWA YUTAKA
IPC: H02P27/06
Filed: 1987-02-02
Abstract: PURPOSE:To improve safety, by detecting power voltage raise to bring a switching element to conduction, and by absorbing regenerating energy to a battery when the voltage at DC power source is raised with the regenerated power in regenerative operation. CONSTITUTION:An induction motor 1 is driven through a three-phase inverter device 3 in a main circuit constitution in which an elevator using an inverter control device and a rescue operating device in power outage are combined, and the elevator is controlled in operation. On this occasion, a battery 20 for absorbing regenerating energy and a power transistor 34 energized by the output of a voltage detector 10 are provided. When the elevator gets in the regenerative operation mode, a motor acts as a generator and the regenerated current flows to the power source side, so that the voltage across a capacitor 4 in the main circuit is raised. With this raise of voltage a regenerating transistor 6 turns On and the battery 20 is charged.

Title: Rotary anode type x-ray tube
Inventor: IWASAKI KENJI
IPC: H01J35/10
Filed: 1979-02-23
Abstract: PURPOSE: To obtain a long-life rotary anode type X-ray tube having a great output by preventing the rise of temperature by raising radiation heat on the surface of a rotary cylinder to support and turn the anode target.  
     CONSTITUTION: The metal coating layer 11 is formed by a gaseous phase growth method on the surface of the rotary cylinder 1 to support and turn the anode target 3, using a material having a higher heat radiation rate than the material of the rotary cylinder 6. Thus, the heat emissivity of the rotary cylinder 6 is greatly raised and thereby the temperature throughout the anode body is lowered. Also, the temperature of the bearings 9 and 10 is lowered. Thus, the vibration of the rotary mechanism is lessened and the life of the X-ray tube is lengthened.

Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of trouble by a failure in operation to wash and regenerate filter media by automatically shifting the operation to a time input mode right after turning on a power source and shifting to an ordinary operation after time setting with a water purifying device which heats the inside of a filter medium container by a heating means controlled by a control means. SOLUTION: When the power source is turned on to the water purifying device constituted by housing active carbon 9 in the filter medium container 8 disposed in a main body case 7, the present position of a selector valve 25 is judged by the outputs from switch sections 39, 40, 41 in a microcomputer and, thereafter, the time input mode is set to light the time part of a display section. Next, the present time is set by pushing the button of the operation section. The selector valve 25 is set at a water stopping state to make the water purifying device into a ready-to-use state after the end of the setting. A timepiece is built in the water purifying device, by which the operation of the control means is executed.  Namely, if the regenerating and washing start time of the arbitrary filter media and the present time are set at this timepiece, the washing and regenerating of the filter media are periodically and surely executed.

Title: Multiple radio repeating installation device
Inventor: OGUCHI TAKUROU
IPC: H04B7/15
Filed: 1978-02-25
Abstract: PURPOSE: To secure the direct repeating without converting the received signal into the intermediate frequency and by means of the phase synchronous circuit.  
     CONSTITUTION: Received signal Fr is introduced to phase synchronous circuit PLL via band pass filter BPF1, amplifier AMP1, shift oscillator SFO and mixer MIX respectively. The PLL comprises phase comparator PD, voltage ontrol oscillator VCO, directional coupler DCP and filter amplifier FA, and transmits the output the phase of which is synchronized with the MIX output via amplifier AMP2 and band pass filter BPF2. Received signal amplitude detector MPD controls sweep oscillator SWR and transmission circuit breaking switch SW when the reception amplitude becomes less than the prescribed value owing to the fading, the fault of the device and other factors. As a result, the PLL can have the normal operation immediately when the reception input is recovered, and also the output of voltage control oscillator VCO which has no synchronization with the received signal can be prevented from being transmitted as the unnecessary wave.
