Patent JP-H051693-A (JP)
Title: Cross flow fan
Inventor: TAMURA KIYOSHI
IPC: F04D17/04
Filed: 1991-06-26
Abstract: PURPOSE:To prevent reduction of pressure certainly, and maintain blowing-out pressure at a high value by providing respective side end parts of the air suction port and the blowing-out port of an inside guide case in close proximity to an impeller, and forming a path between both ends in a circularly recessed shape so as to increase the interval thereto from the impeller. CONSTITUTION:Air sucked from an air suction port 40 into an impeller 10 flows to an air blowing-out port 50 a circular shaped air flow A, and a part of the air flow becomes a vortex B which flows around a center axis (y) located eccentrically toward the inner side from the center axis (x) of the impeller 10. If the shape and a clearance 60 at the intermediate part 33 of an inner guide case 30, are formed in a circular recessed shape and a volume which can accept the vortex B coming out of the impeller 10, an overhang flow of the vortex B from the impeller 10 can be stored inside the space 60 so as to form an independent system of a closed loop. An overhang flow into the clearance 60 by the vortex B acts as a wall opposing to air flow running backward to the suction port 40 side through the clearance 60 from the blowing out port 50 side so as to prevent invasion of the air flow. Since, the air suction side end part 31 of air 30 approaches the impeller 10, it is possible to prevent separation into the clearance 60, of an overhung vortex B on the suction port 40 side.

Title: Camera equipped with camera-shake detection device
Inventor: TANAKA YOSHIHIRO
IPC: G03B7/30
Filed: 1988-07-21
Abstract: PURPOSE:To obtain a detection device which is of practical use by actuating a flat piezoelectric element, whose longitudinal direction is arranged in a specified direction and whose end part which is closer to a release button is fixed to a camera body, in response to an exposure starting action and deciding the existence of camera-shake from a voltage generated by deformation in exposure. CONSTITUTION:The flat piezoelectric element 31 is used for the detection of the camera-shake in a camera and said element 31 is arranged so that the direction of an intersecting line between the surface in which the optical axis of a photographic lens is a normal line and a surface which is parallel with the base 30a of a camera body 30 becomes its longitudinal direction. For example, it is arranged in a slight gap between the upper cover of the camera and the body 30 and also its end part which is closer to the release button 32 is fixed to the camera body 30. And, if the absolute value of the voltage generated by the deformation of the piezoelectric element 31 becomes larger than that of a specified voltage in the exposure, the effect is stored in a storage means and a display means display that the camera-shake occurs in the midst of exposing after completing the exposure. Thus, the camera-shake detection device which is of practical use can be obtained.

Title: Digital-signal recording apparatus
Inventor: WATANABE SATORU
IPC: G11B11/105
Filed: 1991-06-28
Abstract: PURPOSE:To make it possible to judge the logics of multiple values by accurately imparting the magnetic field of an N pole or an S pole into a magneto-optical disk in response to a recording signal and forming a mark corresponding to the N pole. CONSTITUTION:When the magnetic field of an N pole or an S pole is imparted from a magnetic head 35 in response to a recording signal, the mark corresponding to the magnetic field is formed on a magneto-optical disk 31. Different from an optical modulating method, recording operation is positively performed on the magneto-optical disk 31 not only for recording the logic 1 but also for recording the logic 0. Namely, the logic 0 is not recording by not recording the logic 1 after the logic 1 has been recorded, but a part of the logic 1 is erased and then the logic 0 is recorded. In this way, the logic of multiple values can be accurately judged in a partial response method.

Abstract: PURPOSE:To detect surely an edge even at the inside of an isolated point or inside of a minute line by giving a digital signal in the order of a primary differentiation device, an absolute circuit and an adder and using a resulting output as the edge output. CONSTITUTION:A change point of an input digital signal data is detected by the primary differentiation device comprising latches 1-3 and a subtractor 4. After the absolute value of the detection output is obtained by an absolute value circuit 5, the result is fed to latch circuits 6-8. Then an adder 9 sums data strings of absolute values stored in the latches 6, 8 and the result of addition is outputted as the edge output. That is, the adder 9 adds >=2 data except a median among >=3 odd number data in the data string from the absolute value circuit 5 respectively. Thus, an edge is detected surely even at the inside of an isolated point and the inside of a minute line.

IPC: G03H1/02
Filed: 1990-07-13
Abstract: PURPOSE:To enable a stable optical storage for a read-out using a visible light by defining a silicon polymer as a medium, and using a write mechanism with two photon absorption. CONSTITUTION:A YAG laser 11 is used, and the silicone system polymer whose main chain is constituted of a silicone combination is used as a photosensitive medium 19. Two light waves in a complete transmission area are made incident on the photosensitive medium 19 as write lights, a structure change or a phase transition due to the two photons occurs locally at the photosensitive medium 19, and a phase diffraction grating or an amplitude type diffraction grating is written and stored in the photosensitive medium 19. That is, when the photosensitive medium 19 is transparent to the light which operates the write-in and read-out, and is an aborptivity to a second harmonic, the structure and state of the medium can be locally changed by the two photon absorption, and the phase diffraction grating to the read light can be written. Thus, the loss of the light in the recording medium 19 can be reduced, and the information can be stably stored.

Title: Controlling method for variable voltage and variable frequency inverter of induction motor
Inventor: OKAMATSU SHIGETOSHI
IPC: H02P21/22
Filed: 1981-11-20
Abstract: PURPOSE:To reduce the current ripple of an induction motor by selecting the frequency of an inverter which switches a PWM modulation pulse number to become higher at the regenerating time than that at the power driving time. CONSTITUTION:The frequency of a power source which is supplied to an induction motor 4 is controlled by a microcomputer 10, and the voltage is controlled by the output of a subtractor 15. The power driving time and the regenerating time are distinguished during the pulse number switching program of the microcomputer 10, thereby selecting the frequency of the inverter at the time of switching the pulse at the regenerating time higher than the power driving time. Accordingly, a PWM modulation is performed by employing a triangular wave of the pulse motor mostly adapted for the regenerating time, the inverter 3 is controlled, thereby preventing the harmonic component contained in the PWM modulation pulse train from increasing.
