Title: Blur correction type image formation optical system
Inventor: OSHIKIRI MINORU
IPC: G02B27/64
Filed: 1989-06-15
Abstract: PURPOSE:To offer the blur correction type image formation optical system which can use an ordinary interchangeable lens by installing an optical fiber bundle whose incidence end surface is aligned with the plane of image formation by an image formation lens system, and displacing at least one end surface of the optical fiber bundle almost at right angles to the optical axis. CONSTITUTION:An arithmetic unit 7 calculates a correction quantity DELTAy from displacement perpendicular to the optical axis of a camera which is detected by a sensor 6 and an actuator 8 moves the projection end of the optical fiber bundle 3 and the lens 4 by DELTAy at right angles to the optical axis to prevent a decrease due to the blur of an image. Thus, an image which is formed once is shifted in image position by the movement of the projection end surface of the optical fiber bundle 3, so the designing of the image formation lens 2 has no restriction and the image does not deteriorate even when the movement quantity is not limited. Further, the sensor 6, arithmetic unit 7, and actuator 8 can be incorporated in a camera main body, so ordinary interchangeable lenses are used.

Title: Permanent magnet motor
Inventor: KAWAGISHI KENJI
IPC: H02K1/27
Filed: 1985-07-11
Abstract: PURPOSE:To reduce vibrations and noises by inclining the direction of magnetization of a permanent magnet for a motor consisting of an armature winding fed from an inverter generating three-phase AC and a permanent magnet field inclined at an approximately 1.2 radian to a rotating shaft. CONSTITUTION:A permanent magnet motor is formed by an armature winding feeding three-phase AC acquired by inverting DC by an inverter and a permanent magnet field. The direction of magnetization of a permanent magnet is inclined at a radian of theta=1.2 to a rotation shaft. A member such as a magnetizing yoke 1 is used in order to tilt the direction of a magnetized magnetic pole. Slots slanted at the radian of theta=1.2 to the circumferential direction are shaped to the magnetizing yoke 1. Even when the direction of a magnetic pole for the permanent magnet is not leant and the direction of a core slot for the armature winding is tilted at the radian of 1.2 to the direction of the shaft, the same result is acquired. Accordingly, higher-harmonic magnetomotive force is reduced, thus manufacturing the motor hardly generating vibrations and noises at low cost.

Title: Deep-drawing-type packaging apparatus
Inventor: OMORI SHOZO
IPC: B65B11/50
Filed: 1994-06-13
Abstract: PURPOSE:To reliably and correctly stick an open/close fastener to a deep- drawing packaging apparatus which is intermittently transferred. CONSTITUTION:A lower film 5 and a male fastener 21a are held between a driving roller 47 and a following roller 48 which are rotating at an equal speed to be continuously pulled out at the equal speed and supplied to between a heating roller 30 and a receiving roller 31. Since they pass through between both rollers at the equal speed, both 5, 21a can be securely stuck to each other. Then the film is supplied to a transfer path of a main packaging apparatus which is intermittently transferred through a step roller 53 and a fixed roller 54. Force to move downward by a spring 57 functions to the step roller, so that the step roller lowers while the main apparatus temporarily stops and the step roller elevates while the main apparatus is transferring the film, thereby absorbing difference between a moving state (continuous) of the roller on the heating roller side and a transfer state (intermittent) on the main apparatus side to allow smooth supply.

Title: Immersion heater for nonferrous metal solvent bath
Inventor: SHIBUYA MASAO
IPC: H05B3/78
Filed: 1988-06-20
Abstract: PURPOSE:To uniformly heat a solvent bath with a protecting tube immersed completely in it by forming a conductor coating part of insulating fire material which covers the space that is coming out of a protecting tube of a conductor to outside the furnace. CONSTITUTION:In a conductor 13, one end being connected to a resistance exothermic material 12 and the other to a power supply part, a conductor coating part 14 is formed in between the exit part of the protecting tube 11, and an exit part to the outside of a furnace. Since the conductor coating part 14 made of an insulating fire material is formed on the conductor 13 for a resistance exothermic material which is derived from the protecting tube 11, the entire protecting tube 11 can be used with being immersed completely in a solvent bath 37 so as not to be pulled out into the space inside the furnace. The temperature of the protecting tube 11 is thus not to be raised no greater than the temperature of the solvent bath 37, and the adhesion of oxides on the surface of the protecting tube 11 can be prevented.

Title: Magneto-resistance effect type head and production thereof
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1988-06-20
Abstract: PURPOSE:To allow the magnetic reproduction of extreme narrow tracks without lowering the reproduction sensitivity of the head by applying the magnetic field of a permanent magnet via the legs of a magnetic material to a magneto- resistance effect element. CONSTITUTION:The legs 12-1, 12-2 of the magnetic material are drawn out respectively of both ends of the magneto-resistance effect element 10 and both ends of the permanent magnet 14 which suppresses the Barkhausen noise of the magneto-resistance effect element 10 are respectively magnetically coupled to both the legs 12-1, 12-2. Since the magnetic field H of the permanent magnet 14 is indirectly applied via the legs 12-1, 12-2 of the magnetic material to the magneto-resistance effect element 10 and the magnetic field H is not directly applied thereto, the magneto-resistance effect element 20 is kept free from the application of the strong magnetic field to the extent of lowering the reproduction sensitivity of the head. The degradation in the reproduction sensitivity of the head is prevented in this way and the track width of the medium is narrowed, by which the easy formation of the magnetic recording device to a larger capacity is enabled.

IPC: G11B5/027
Filed: 1984-07-24
Abstract: PURPOSE:To perform less-distortion recording by determining the quantity of negative feedback on the basis of a voltage depending upon the inductance of a head. CONSTITUTION:The gain of an amplifier for detection is r+R/r (R: resistance value of magnetic head), so the voltage across a detection resistance (r) is Ir where I is the head current, and the output voltage of the detection amplifier 12 is (r+R/r)Ir(r+R)I. When a bias trap circuit, etc., are ignored, on the other hand, the voltage of the output stage of a recordint amplifier 5 is I(R+r+ZL), where ZL is the impedance depending the inductance of the head. The impedance ZL becomes larger and larger as the voltage IZL depending upon the inductance and the frequency become higher and higher, and the current I decreases to the contrary, so no frequency characteristic is obtained. A frequency compensating circuit 14, however, is provided, so negative feedback control under which a constant current characteristic to the frequency is obtained is provided.
