Title: Electromagnetic sound wave transmitter and receiver
Inventor: AJISAKA HIDEMI
IPC: H04R1/44
Filed: 1990-05-01
Abstract: PURPOSE:To easily generate a sound wave having frequencies over a comparatively wide band including a low frequency band with simple structure by arranging a solid conductor in a magnetic field in water and supplying an AC current to the conductor in a direction orthogonal to the direction of the magnetic field so as to induce a sound wave through the selection of the length of the conductor. CONSTITUTION:The above transmitter-receiver 1 consists of a magnet 2 and a conductor 3 or the like, a solid conductor having no hollow in its inside is employed for the conductor 3 and arranged in space between the N and S poles of the magnet 2 with an insulator 5 inbetween. An AC current distribution panel 6 is fitted to an upper and a lower face of the conductor 3 in close contact with each other and the AC current is almost uniformly distributed in the entire cross section of the conductor 3 from an AC power supply 4 while being distributed by the AC current distribution panel 6. Since the conductor 3 is placed in a magnetic field, an electromagnetic force F is exerted to the conductor 3 in the lengthwise direction of the conductor 3, from which a sound wave is generated. A choke member 7 is closely provided to one of both end faces of the conductor 3 thereby sending the sound wave only in one direction. Moreover, the conductor 3 receiving the sound wave causes minute vibration, an electromotive force E is generated in the conductor 3 in the orthogonal direction with respect to the magnetic filed, it is measured by an AC voltage detector 9 thereby receiving the sound wave.

Title: Optical information recording and reproducing device
Inventor: GOTOU YOSHIKAZU
IPC: G11B7/09
Filed: 1984-06-06
Abstract: PURPOSE:To apply stable focus control to a disc having a guide pit by using a focus gain switching circuit for tracking on/off in common as a focus gain switching circuit for reproduction and recording. CONSTITUTION:The focus gain switching circuit has a low gain setting with a tracking-off command signal with focus control-on and tracking-off at first, and even when an external disturbance signal exists in a focus error signal, a drive voltage of a focus control circuit 12 is not saturated and no out-of-focus is caused. Then tracking control is applied with the tracking-on command and since no guide pit exists, the effect of an external disturbance signal due to crossing of guide pit is given on a focus error signal and the tracking performance of focus is improved by increasing a focus-through gain. A focus gain switch circuit 16 is brought into a high gain setting by a tracking-on command signal, the tracking performance of focus is improved at on-state in comparison with off-state and excellent recording/reproduction is attained.

Title: Conveyor for lead frame
Inventor: TAKANO HIDEAKI
IPC: H01L21/50
Filed: 1987-05-13
Abstract: PURPOSE:To quickly cope with a change from one type of lead frame to another by altering the amount of movement of a lead frame, inputting data on the shape of its island, and properly adjusting the position of a lead-frame deflection preventive rail. CONSTITUTION:An island-position recognizing section 29 transmits an image from a camera 16 over a monitor 28, and detects the position of an island in a lead frame. An arithmetic operation section 30 computes the quantity of displacement to the set position of the detected position of the island. The position of the island is corrected by controlling the drive of a pulse motor 9 on the basis of the quantity of the displacement. The type of lead frame can be varied only by altering the number of pulses of the pulse motor 9, changing the position of a lead-frame deflection preventive rail 126 and inputting data on the shape of island. The number of pulses of the pulse motor 19 at the time of the carrying of the lead frame is set to the number where previous island-position correction-quantity is fed back. The island-position correction time is shortened or made useless.
