Title: Structure for rotor of synchronous motor
Inventor: HAYASHI YOSHIYUKI
IPC: H02K1/27
Filed: 1987-01-26
Abstract: PURPOSE:To reduce the amount of a magnetic material used, by making the thickness and width of magnets on the outer periphery of a rotor core at the central parts in the circumferential direction of the same larger than the same of the magnets at the ends of the rotor core. CONSTITUTION:A rotor consists of an octagonal rotor core 12, fixed to a shaft 10, and 8 pieces of magnets 14, bonded and fixed to respective sides of the rotor core 12. The outer periphery of the magnets 14 forms a circle and the thickness (t1) of the central parts 16 of the magnets is formed larger than the thickness (t2) of the same at the edge parts 18. Farther, the magnets are constituted so that not only the thickness of the circumferentially central parts 16 of the magnets 14, deployed on the rotor core 12, is made larger than the thicknesses of the circumferentialedge parts 18 of the same but also the width of the magnets in the central axis 11 of the rotation of the rotor at said central parts 16 is formed larger than the width of the same at the edges 18. According to this method, the central part 16 of the magnet may be less affected by the magnetic field of the opposite direction thereof.

Title: Slab type solid state laser device
Inventor: YUASA HIROSHI
IPC: H01S3/091
Filed: 1987-01-26
Abstract: PURPOSE:To prevent distortion from occurring on a wave surface, by making laser medium portions, which are covered with holders, serve as inactive parts which contain no active ions and preventing a temperature rise of the inactive parts. CONSTITUTION:Active ions are contained into an excitation region of a laser medium 11, whose both ends are supported by holders 18, so as to form an active part 12. On the other hand, laser medium 11 portions which are covered with holders 18 are made to serve as inactive parts 16 which contain no active ions. Thus, even if excited light L from an excitation lamp 14 enters the inactive parts 16, the excited beams L are absorbed into the inactive parts 16, so that a temperature rise thereat can be suppressed. Therefore, a temperature difference between the active part and the inactive parts can be made steep to narrow a temperature lapse region, so that optical lengths of laser beams can be prevented from varying with positions where the laser beams become incident in the thickness direction of the laser medium, and distortion can be prevented from occurring on a wave surface.

Title: Photoconductive type display device
Inventor: SUGIYAMA ATSUSHI
IPC: G02B6/04
Filed: 1988-01-25
Abstract: PURPOSE:To decrease a ratio to generate a complete defect on a display surface and to suppress the fall of a display fidelity due to the dispersion of luminance to a minimum by making information for >=two picture element portions formed with an image forming device correspond to one photoconductor. CONSTITUTION:For one photoconductor 102 indicated by dotted lines, in a photoconductive type display device, to which total 6 picture elements 101 of three primary colors R, G and B correspond, the added information of the six picture element portions are outputted to a light emitting surface. Consequently, even when information is omitted due to the defect of approximate one picture element out of the six picture elements, probability to become the complete omission of the specific color information for the picture element on the light emitting surface, namely the complete defect, is reduced, and a receiving effect becomes smaller. An optical shutter in such a case allocates the same information to the respective two R, G and B picture elements, and can decrease a display information quantity per an LCD. In the picture element having no defect and being added with the two picture elements on the display surface, the dispersion of luminance is reduced.

Abstract: PURPOSE: To heighten the efficiency of purification of exhaust gas, by adding an acceleration detector and a compared voltage shifting circuit.  
     CONSTITUTION: The acceleration detector 10 consisting of a negative-pressure- operated diaphragm 11 and an acceleration switch 19 is connected to a negative pressure port 12 of an intake passage 5 through a passage 13. The compared voltage shifting circuit 40 is connected to the acceleration switch 19. When the load on the engine rises drastically, the negative pressure of the intake pipe falls drastically and only a second chamber 16 is maintained at strong negative pressure for a predetermined time by the action of a negative pressure delaying valve 15. Therefore, a rod 18 is pulled down by the negative pressure of the second chamber 16, the acceleration switch 19 is turned on, a coil 43 is energized and a change-over switch 44 of the compared voltage shifting circuit 40 is shifted, so that the set level of a reference voltage is changed. Thereby, the air fuel ratio is controlled to be rich for the acceleration. Thus, the thinning of the air fuel mixture due to the wrong follow-up property of additional fuel supply etc. is corrected and an aimed air fuel ratio is obtained.

Title: Non-contacting power feeding facility
Inventor: NISHINO SHUZO
IPC: H02J50/00
Filed: 1994-02-10
Abstract: PURPOSE:To provide a non-contacting power feeding facility that protects its power supply. CONSTITUTION:A pair of guiding lines 34 are installed along the moving line of a vehicle V so as to supply a high-frequency electric current through the lines 34 from a power supply M, and a pickup coil 36 is provided on the vehicle V so as to receive the electric power from the lines 34 in a non-contacting state. Then a resonance capacitor 55 is connected to the starting ends of the lines 34 and capacitors 57 are connected in parallel with the lines 34 at prescribed intervals, with both ends of adjacent capacitors 57 being connected to each other through zero-impedance cables 58. The cables 58 are not laid between the capacitor 55 and the capacitor 57 in the first stage. As a result, the high-frequency pulse-like current generated by the power unit M is prevented from returning to the unit M after flowing through a whole circuit, because the pulse-like current is blocked by the inductance of guiding lines 36 in the first stage. Therefor, damage to the power unit M can be prevented and the loss of the unit M can be reduced.
