Title: Scanning optical system
Inventor: YOSHIDA YUKIHIRO
IPC: H04N5/378
Filed: 1987-07-01
Abstract: PURPOSE:To obtain a picture with high resolution without generating a scanning error by vibrating a light transmission plate by a signal obtained by attenuating the resonance frequency band of an output signal from a light transmission plate driving signal generator. CONSTITUTION:A frequency component equal to the primary -N-th resonance frequency out of a driving voltage fetched from a signal generator 10 is attenuat ed by a band check filter 11 and the attenuated signal is amplified by an ampli fier 12 to drive piezo actuators 4a, 4b. Since the actuators 4a, 4b are driven by a signal previously attenuated at its frequency component equal to the reso nance frequency by the filter 11, no distortion is generated in the vibrating deformation and a frequency response goes to flat. Thereby, the light transmis sion plates 1a, 1b can be linearly driven, no error is generated in optical scan ning and the resolution of a solid-state image pickup element can be prevented from being lowered.

CrO2 powder is prepd. and is coated on a nonmagnetic base and thereafter, a pair of AC magnetic field generators 2, 3 are disposed to face each other in the direction orthogonal with the magnetic coated film surface 1a of the magnetic recording medium 1 in the state in which the coated film is not yet dried and is flowable. AC rotating magnetic fields are then impressed to the recording medium 1 while said medium is kept rotated. The phase characteristic deviates by as large as about 90 deg. from a master tape if the CrO2 powder is completely perpendicularly oriented, i.e., if the squareness ratio in the perpendicular direction is increased too high at this time. The squareness ratio in the perpendicular direction after the correction of a diamagnetic field is thereupon confined to 40-70% and the ratio of the squareness ratio in the perpendicular direction where the correction of the diamagnetic field is not made and the squareness ratio in the intra-surface direction is confined to >=0.5, by which both of the high output and the phase characteristic are satisfied.

Title: Delivery pressure controller for pump
Inventor: SONE SHIGEO
IPC: F04B49/00
Filed: 1979-12-21
Abstract: PURPOSE: To perform the water supply continuously at constant delivery pressure irrespective of the characteristic of the pump or the variation of supply water, by controlling the rotation of pump such that the delivery water pressure is maintained continuously at the setting level.  
     CONSTITUTION: The water supply pump 1 is driven by a motor 2 through a hydraulic clutch 3. In such region where the delivery water pressure PW is lower than the pressure pre-set for the pump 1, the rotation of the pump 1 is increased because a hydraulic pressure inlet port 12 and a hydraulic pressure outlet port 13 are in open state thus to increase the delivery water pressure PW. When the delivery water pressure PW exceeds the setting level, pistons 10a, 10b move further to the spring side 11 to open the drain port 14 and to decrease the clutch hydraulic pressure PCL. Consequently the slip of the hydraulic clutch 3 increases to decrease the rotation of the water supply pump 1 thus to lower the delivery water pressure PW thereby the water is continuously supplied with constant delivery pressure even in this case.
