Title: Rotating electric machine
Inventor: NOSE TAMOTSU
IPC: H02K23/62
Filed: 1993-01-28
Abstract: PURPOSE:To make it possible to significantly improve a T/N characteristic value of a rotating electric machine with a simple structure, and to achieve a smaller rotating electric machine. CONSTITUTION:By virtue of the configuration of yoke plates 26 and 28 attached to field magnets 27, the whole magnetic flux of the field magnets 27 is concentrated onto iron cores 23 of an armature while the magnetic flux is inverted. Multiple poles are realized by the structure that causes the whole magnetic flux of the field magnet 27 to be concentrated without dispersion thereof. For this reason, it is not necessary to carry out multipolar polarization of field magnets in the manner as is conventionally practiced. Moreover, the magnetic flux of the field magnets 27 can be constantly utilized up to the maximum while the simple construction of the armature is maintained. This makes it possible to simultaneously increase both an effective magnetic flux PHI and the number of poles. A simple construction is obtained by disposing the iron cores 23 having different phases in an arrangement which constitutes a parallel magnetic circuit.

CONSTITUTION:A joint 15, shifting a bubble from an ion implantation transfer path 13 to a permalloy transfer path 14, has an approximately linear ion implantation boundary 12 that extends from the -1-12 direction of crystal to the 11-2 direction. If a bias boundary to hold a bubble points upward with respect to the crystal, the timing when the bubble passes by the boundary 12 is when an interface magnetic field to drive the bubble lies within a phasal range of 30 deg.-90 deg. covering from the normal direction to the ion implantation area 10 in the boundary 12 to the 11-2 direction. Thus the proceeding direction of the bubble coincides to the direction where a potential becomes deeper, and bubble drive force is improved to enhance an action margin.

Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To enable frost generated at an inlet side of a discharging passage of a heat exchanger in a heat exchanging type ventilation device to be easily removed with cooled fed air. SOLUTION: This heat exchanging type ventilation device is operated such that an operation of an air feeding blower 5 and an operation of an air discharging blower 6 are started concurrently during its normal operation and an air feeding flow A and an air discharging flow B are flowed through a heat exchanger 2. As the cooled and fed air flow A flows, frosting is generated at a passage inlet side of the heat exchanger 2 where the heated air discharging flow B is flowed. This control device for the ventilation device is operated such that as an air speed of the discharged flow B detected by an air speed sensor 7 becomes less than a first set value due to frosting, an intermittent operation control means 11 is operated and an air feeding blower 5 is stopped in operation until an air speed of the air discharged flow B is recovered.

Abstract: PROBLEM TO BE SOLVED: To perform the filter processing geared to the revolution of a motor by switching the filter processing for lessening the influence of noise by a frequency command, to the frequency command by the analog voltage inputted by a first setting means. SOLUTION: In the case of issuing the frequency command by an analog voltage input value, the influence on the frequency command by noise becomes larger when the output frequency is low than when it is high, therefore as the filter time constant for noise removal, the two kinds of a filter time constant for high speed and a filter time constant for low speed are prepared in an EEPROM 14 in advance, and the filter processing is performed, switching both filter time constants, according to the output frequency. Hereby, the filter processing geared to the revolution of a motor can be performed, so the removal of noise and the security of responsiveness of a high-speed region become possible.

Title: Hydraulic automatic tensioner
Inventor: KAWASHIMA KAZUTAKA
IPC: F16F9/40
Filed: 1990-02-14
Abstract: PURPOSE:To improve the damping characteristics at the starting time at low temperature by installing a separator forming a minute clearance between the outer diameter surface of the push rod facing to the outside of a body and the separator in a reservoir chamber. CONSTITUTION:Hydraulic oil is charged in a pressure chamber 13 and reservoir chamber 14, and an air layer 25 is provided at the upper section of the reservoir chamber 14. A conical separator 26 is fitted around the push rod 18 in the reservoir chamber 14. Since the clearance 27 between the opening edge of the small diameter end of the separator 26 and the external peripheral surface of the push rod 18 is small, at the starting time at low temperature when a piston 12 is rapidly moved toward the reservoir chamber 14, the clearance 27 displays a contraction effect for raising the pressure of hydraulic oil between the separator 26 and the piston 12. Thus, the damping characteristic at the starting time at low temperature can be improved.

Filed: 1978-03-24
Abstract: PURPOSE: To enable deteriorative faults of inspection systems utilizing ultrasonic waves or the like to be rapidly diagnosed by using an inspection plate having a reference flaw and comparing the attenuation quantity and threshold attenuation quantity to the reference flaw.  
     CONSTITUTION: Prior to ultrasonic flaw detection of a thick plate 1 being the target under inspection, the thick plate 1 is substituted with a reference inspection plate which has a fixed reference flaw. When inspection is performed in this state, the crest value when the reference flaw is detected is outputted from a sampling circuit 39 and is inputted to a level setting circuit 42. In the above circuit 42, the comparison with the referenc crest value for the reference flaw is performed and an attenuator 36 is automatically controlled until the difference thereof becomes zero. The atenuation quantity of this attenuator 36 is compared with the threshold attenuation quantity in a comparator 43 and when it is smaller then the threshold attenuation quantity, the signal indicating that the probe 2a has deteriorated is outputted. In this way, the detriorative faults of the inspection system may be diagnosed and the cost of maintenance reduced.

Filed: 1990-02-16
Abstract: PURPOSE:To obtain a handy portable information processor designed nicely by attaching movably a keyboard to the processor main body, and providing a driving mechanism which drives the keyboard in accordance with the rotation of a top case. CONSTITUTION:A keyboard 3 is attached movably to an information processor main body 1 via the front part of the keyboard 3. A rotary mechanism consists of the links 7 and 8, and a compression spring 9 and drives the keyboard 3 in accordance with the rotation of a top case 2. When the case 2 is opened, the link 8 rotates and is pushed up toward the back of the keyboard 3 by the spring 9 to protrude over the inner surface of the main body 1. Thus the thickness of the case 2 is reduced since the keyboard 3 is stored in the main body 1 when the case 2 is closed, so that the handy portable information processor can be obtained. Furthermore it is not required to provide a rib to the inner surface of the case 2 in order to prevent a contact between the keyboard 3 and the case 2. Therefore the inside of the case 2 can be formed flat and a nice external design is ensured for the processor.
