Title: Rotary type compressor
Inventor: IWATA HIROSHI
IPC: F04C18/356
Filed: 1981-12-17
Abstract: PURPOSE:To decrease electric power consumption for a solenoid to hold a vane by installing a permanent magnet within the solenoid in order to induce an attractive forece to attract a movable core to a fixed core for holding the vane. CONSTITUTION:When a demagnetizing coil of a coil 36 is energized while the electrification to an attracting coil is set to OFF, an electromagnetic field to cancel the magnetic field of a permanent magnet 39 is generated, and the attractive force by the permanent magnet 39 disappears so that only spring force acts on a movable core 37. When the movable core 37 moves to the reach a stroke position the relationship, the spring force is greater than the attractive force, holds again. Thus even if the electrification to the demagnetizing coil is set to OFF, the movable core 37 is stopped. In other words, the electrification is required only for the period during whilch the movable iron core 37 moves by the amount of a stroke. Thus the electric poser consumption of the solenoid 34 can be reduced to 1/10 to 1/20 the conventional value.

Title: Spiral antenna
Inventor: HARA SHIGEO
IPC: H01Q11/04
Filed: 1984-09-27
Abstract: PURPOSE:To obtain a spiral antenna which is hardly affected by a higher order mode and reflecting waves from the bottom, has a wide band directivity, and is light in weight, by constituting a conductive cavity by using a CFRP. CONSTITUTION:A conductive cavity 3 is constitute by using a CFRP. When the cavity 3 is constituted in such a way, radio waves are radiated to both upper and lower sides of an antenna base 1 by a high-frequency electric current flowing to a spiral arm 2 through a connector 6 and balun 4, but the radio waves radiated to the lower side reach the base of the CFRP cavity 3 after they are damped by a wave absorber 5. However influences of the radio waves reaching the base of the cavity 3 to the radio waves radiated to the upper side become less, because the conductivity of the CFRP is lower than that of a metal by several figures. In addition, the degree of the influence to the radiation pattern also becomes less, since a higher order mode produced due to the existence of the side face of the cavity is also damped on account of the low conductivity of the CFRP. Furthermore, because of the CFRP being about a half of aluminum in specific gravity and equivalent to the aluminum in strength, the antenna can be reduced in weight.

Title: Input/output control system
Inventor: OJIRO YOSHIFUMI
IPC: G06F3/06
Filed: 1989-08-04
Abstract: PURPOSE:To easily recover the fault of an input/output control system by trans ferring the due data to a system storage and then to a magnetic disk device when an instruction is received to transfer the data to a magnetic disk storage from a main storage device. CONSTITUTION:A processor #201 of a channel device #02 receives an SSCH instruction and transfers partly the data on a data area #401 of a main storage device to a buffer #202. The buffer #202 transfers the received data to a buffer area #501 via an MRQ circuit #203. This action is repeated several times for confirmation of a fact that the data are normally stored in the area #501. Then the processor #201 gives an instruction to a channel interface circuit #204 to start an I/O process. A normal I/O process is carried out to transfer the data stored in the buffer #204 to a DASD #01. Thus it is possible to reduce the task halting time down to several seconds or so at the occurrence of a fault.

Title: Acquisition and tracking system for target light source
Inventor: ICHIKAWA SHIGEYUKI
IPC: G01S3/785
Filed: 1988-08-17
Abstract: PURPOSE:To track only a target radiation source with high accuracy by discriminating between the optical radiation body to be detected and its background with the pulse train of a scan signal. CONSTITUTION:A reticle modulated signal which is passed through a reticle 1 and obtained through an infrared detector 2, a preamplifier 3, a band-pass filter 4, and an AGC circuit 5 is converted into a binary signal by a level comparator 6 where a comparison value corresponding to a target is set. When its output goes up to a high level, a level holding circuit 7 generates an uncaging output only for a constant period and the output is passed through an OR gate 11 to track the light source in the meantime. Then the reticle modulated signal for the target has a waveform of almost single frequency with a stable level, but a signal generated by a background radiation body larger than the target has a waveform which is disordered in level and frequency. This waveform is shaped by a level comparator 8 and its pulses are counted 9 at a constant period to discriminate between the target and background.

Title: Apparatus and method for checking magnetic disk
Inventor: TANAKA SHOJI
IPC: G11B5/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To improve reliability in error checking of a magnetic disk having a track pattern without adding a new mechanism. SOLUTION: In a certifier that performs error checking of a PERM disk in which concentric track patterns are provided, a track width Twh of a reproduction head 2a is set to be substantially equal to a track pitch p1 of the PERM disk. During the error checking to be performed, when a check signal on a data track DT is read out by the reproduction head 2a, the reproduction head 2a traverses the data track DT since eccentricity exists between the center of tracks on the PERM disk and the rotation center of the PERM disk. A portion of the track width Twh of the reproduction head 2a that corresponds to a portion thereof existing in the outside of the data track DT is controlled to overlap the adjacent data track DT'. Thus, the effective track width that contributes to the reproduction of the reproduction head 2a is always maintained at substantially a constant value.
