Title: Ink jet recording apparatus
Inventor: AMAMIYA ISAO
IPC: B41J2/16
Filed: 1995-03-14
Abstract: PURPOSE: To enable high-resolution recording of recording dots without requiring a highly advanced machining technology or a complicated drive method, by providing means for specifying the flying direction of ink droplets so that the interval between ink droplet-landing points on a recording medium is shorter than the interval between ink ejecting points. CONSTITUTION: A recording head 21 comprises a plurality of piezoelectric oscillators 8 provided on a concave substrate 9, and a piano-concave acoustic lens 20 provided thereon for converging ultrasonic waves generated thereby. Provided over the acoustic lens 20 are an ink chamber 3 and a slit-like nozzle unit 10. It is designed that the geometric centers of the slit-like nozzle unit 10 and the concave substrate 9 coincide with the center axis of a cylindrical recording paper support roller 5. Thereby the ink droplets ejected from the nozzles 10 fly toward the center of the concave face where the nozzles 10 are arranged.  Since the interval between flying ink droplets decreases as they fly farther, the ink droplet interval is shorter than the interval between the ink ejecting points when the ink droplets reach and stick to recording paper 7 supported on the peripheral face of the roller 5.

Hence, in spite of scattering of high-temp. molten metal during welding work, the stationary guide bars 3 are protected with high probability. Some spaces are created between the tapes 17, 18 on the slider 6 side and positioning means 23, 24, and these spaces and the space 14 communicate with each other, but since the surface areas of the communicating parts are so small that they are virturally of no problem.

Title: Apparatus and method for control of motor
Inventor: KUWABARA SHIGETO
IPC: H02P25/10
Filed: 1990-03-08
Abstract: PURPOSE:To maintain the maximum energy saving effect of an induction motor by a method wherein a measured power factor is compared with a set power factor and a power factor comparison signal is generated and a voltage supplied to the winding of the motor is regulated to have the measured power factor close to an optimum power factor. CONSTITUTION:When the load of a motor is large, a measured power factor Pfm is higher than a set power factor Pfs. At that time, as the level of a power factor comparison signal C is low, the pulse width of a square wave signal D becomes large. As the pulse width of a gate driving signal G also becomes large at that time, the conduction angle of a TRIAC 46 becomes large. Therefore, the conduction period of the TRIAC is extended and a voltage applied to the winding of the motor 12 becomes high. Thus, the voltage applied to the winding of the motor 12 is regulated in accordance with the level of the power factor comparison signal C, so that the motor 12 can be operated constantly with the set power factor.
