Title: Low-speed high-torque motor
Inventor: HASHIMOTO ICHIRO
IPC: H02P6/08
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a stable current command value by reading out a digital amount written in a memory in response to a rotor position by utilizing a speed detecting encoder pulse, and A/C-converting it as a current command. CONSTITUTION:A sensor coil 12 is wound on one pole of a stator, and as a rotor rotates. the coil generates an induced voltage having 90 cycles per revolution. A noise is removed by a filter from the voltage to obtain reference pulses at a rate of 90 per revolution. A signal obtained from an encoder 7 is multiplied by 4, and fed together with a speed controller to a counter. An approximate digital amount obtained by dividing a sine wave and a cosine half wave by the ratio of the encoder signal to the reference pulse is recorded in a memory, and read out in response to the number of counts of the counter as a current command.

Title: Position setting mechanism for excavator
Inventor: KISHI MITSUHIRO
IPC: E02F9/12
Filed: 1984-03-06
Abstract: PURPOSE:To simplify the handleability of an excavator by a method in which a position detector is provided to the excavator to control the amount of oil to be supplied and also to synchronously operate a slewing base and a working base in such a way as to automatically correct the deviation of synchronism. CONSTITUTION:In an excavator in which a slewing base 14 and a working base 20 are synchronously operated by separate oil-pressure motors 18 and 41 by controlling the amount of oil to be supplied, position detectors 45 and 48 consisting of limit switches 46 and 49 and contact pieces 47 and 50 are provided between the vehicular body and the slewing base 14 and between the slewing base 14 and the working base 20. The slewing base 14 and the working base 20 are turned to a reference position and automatically stopped for setting the synchronous positions only by pushing a compensating switch by interlocking the limits switches 46 and 49 with the solenoid valve of the oil-pressure system. The needs for manual operation to correct the deviation of the synchronous positions can thus be eliminated, and the operation can be simplified.

Title: Magnetic encoder
Inventor: HATTORI TETSUO
IPC: G01B7/00
Filed: 1988-02-25
Abstract: PURPOSE:To obtain the magnetic encoder which has a small error even if its ambient temperature varies by providing a temperature-sensitive expanding means which narrows down the gap between a magnetic scale and a magnetic sensor head as the in-use temperature rises and widens the gap as the temperature falls. CONSTITUTION:A housing 2 is made of a material which as a smaller coefficient of heat expansion than the Al alloy of a drum. When the ambient temperature rises, the expansion in the radial direction of the drum is larger than that in the radial direction of the housing 2 because of the difference in coefficient of heat expansion, so the gap between the magnetic scale 1 and magnetic sensor head 5 is narrowed down. The magnetic field that the magneto-resistance effect element of the head 5 senses increases in intensity to cancel a decrease in sensitivity due to the temperature rise. When the temperature falls, the gap between the head 5 and scale 1 becomes wider and the magnetic field intensity of the magneto-resistance effect element decreases, but the sensitivity of the magneto- resistance effect element increases. Consequently, the magnetic encoder which has a small error even if the ambient temperature varies is obtained.

Filed: 1986-02-28
Abstract: PURPOSE:To remarkably improve sepn. performance by providing nozzles which inject a condensible gas in the same direction as the whirling direction of a liquid to be treated to a sepn. barrel at the points near the inside peripheral surface thereof. CONSTITUTION:The nozzles 9, 10 are provided to the side wall of the cylindrical part 2 of a cyclone type solid-liquid separator to be used for a retreatment plant for nuclear fuel, etc. These nozzle are provided in the position slightly lower than the position where an introducing pipe 2 for the liquid to be treated is provided.

Title: Print head for printer
Inventor: KOBAYASHI YUKO
IPC: B41J2/28
Filed: 1989-02-27
Abstract: PURPOSE:To lengthen the service life of a printer and to obtain a highly reliable print head by employing different materials having identical hardness for the armature and the core in the print head for a wire dot printer. CONSTITUTION:When a print head 1 does not perform printing operation, an armature 17 is attracted to the end face of a core 16 through the magnetic force of a permanent magnet 14 and a print hammer 7 is biased toward the core 16. When current is fed to a coil 13 and a magnetic field is produced in a reverse direction from the magnetic field of the permanent magnet 14 in order to cancel the magnetic field of the permanent magnet 14, the print hammer 7 is separated through a leaf spring being biased and a print wire 4 springs out from the tip of the nose 8 and collides against an ink ribbon and a print medium, thus forming a dot. Upon interruption of current supply to the coil 13, the armature 17 is attracted again to the core 16. When different materials having identical hardness are employed for the armature 17 and the core 16, friction on the colliding face is reduced, resulting in the improvement of the service life and the reliability of the print head 1.

Filed: 1987-02-27
Abstract: PURPOSE:To facilitate the disposal of paper jams and the replenishment of paper sheets by providing a sheet loosening mechanism and a paper feed roller, integrally with a sheet tray so that they may be pulled out together with the sheet tray. CONSTITUTION:When a sheet tray 1 is inserted, the upper surface of a bracket 10 is pressed by the guide surface 26 of a guide plate 25, and is gradually lowered. When the sheet tray 1 is completely set in a paper feed section, it is set in a condition in which a paper feed roller 12 is pressed against the upper surface of sheets 12. When the sheet tray 1 is pulled out from the copying machine body, the tray 1 is gradually raised along the inclination of the guide surface 26 since the bracket 10 is rotatably arranged above by means of a spring 11, and therefore, the paper feed roller 12 is separated from the sheets. When the tray 1 is completely pulled out, the paper feed 12 is swung to and held at a position where the loading of the sheets is not hindered.

Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To prevent the loss of data in advance by counting the frequency of occurrence of an event being a sign of fault occurrence, to automatically detect that the event being a sign of fault occurrence is generated in an information storage part. SOLUTION: The frequency in occurrence of a write/read error and that of a write/read retry are counted in a storage part error accumulation table as events being signs of fatal fault occurrence in HDD devices 4A and 4B in store computers 1A and 1B. The frequency of occurrence of a write/read error is also counted as an event being a sign of fatal occurrence in a D-RAM. For example, if there is a difference between the current accumulated value of the HDD error and the preceding one in the store computer 1A and the current accumulated value exceeds a preliminarily set alarm total frequency, a fault occurrence prevention report message of the HDD device 4A is automatically transmitted from the store computer 1A to a host computer 7.

Title: Variable displacement compressor
Inventor: KAWAGUCHI MASAHIRO
IPC: F04B27/14
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a variable displacement compressor capable of improving acceleration performance by detecting the acceleration state of an engine for a vehicle and changing discharge displacement from large capacity to small capacity. SOLUTION: A boosting passage 24 communicating a discharge chamber 13b with a crank chamber 15 is provided on a cylinder block 12 and a differential pressure valve 31 is disposed in the passage 24. A valve element 33 constituting this differential pressure valve 31 is energized to a location where the passage 24 is always closed by a spring 34. When pressure Pd within the discharge chamber 13b rapidly rises in an acceleration state of a compressor, pressure within a second pressure sensitive chamber 45 rises and thereby a spool 42 and a rod 43 open the valve element 33 against energizing force of a spring 48.  Therefore, gas in the discharge chamber 13b is supplied from the boosting passage 24 to the crank chamber 15, pressure Pc within the chamber 15 is enhanced, an inclined angle of a swash plate 19 is reduced, the compressor is switched from a large capacity operation to a small capacity operation and acceleration performance is improved.
