Title: Pickup controller
Inventor: OONISHI JIYUNICHI
IPC: G11B3/10
Filed: 1982-12-14
Abstract: PURPOSE:To prevent sufficiently the resonance of a pickup arm by placing a pickup and a record disk in invariably constant relative position relation on the basis of a signal corresponding to the phase difference between a transmission wave sent from a transmitter to the record disk and a reception wave which is reflected by the record disk and received by a receiver. CONSTITUTION:The phase difference between the transmission wave and reception wave is assumed to be zero when the height H from the transmission surface of the transmitter 1 and the reception surface of the receiver 2 is larger than specific reference height H1. When the height H becomes slightly larger than the reference height H1, a positive or negative phase difference corresponding to the variation in height is made. A phase comparator 12 outputs a zero- level phase difference signal when the height H is equal to the reference height H1 and outputs a positive or negative phase difference signal corresponding to the height between the transmission wave and reception wave. This phase difference signal is supplied to a vertical driving control part 14 which controls the motion of the pickup arm 7 in a vertical plane by controlling the driving of a vertical driving part 13.

Abstract: PROBLEM TO BE SOLVED: To use LEDs without receiving much undesirable noise by mounting the LEDs on a printed circuit board, connecting them to one side of the printed circuit board, and connecting the terminals from a modular jack to the other side of the printed circuit board. SOLUTION: A modular jack 410 is provided with an insulating housing having a top wall 412, a bottom wall 414, sidewalls 416, 418, a front side 420 and a rear side 422.

Discharge heating 19 is performed again to fuse the core parts projecting in the conic shape, and then a microlens 20 is formed on the end surface of the optical fiber 14 by surface tension. At this time, the discharging current and discharge time are adjusted to the microlens 20 with optional curvature on the end surface of the optical fiber.

Abstract: PROBLEM TO BE SOLVED: To prevent an upset of luminance balance between color light sources by providing a light quantity control circuit which supplies a light quantity control signal to a light source driving circuit in accordance with a detected value by a photosensor, adjusting the luminance level of each light source and keeping the luminance balance of a desired color between the respective color light sources constant. SOLUTION: The photosensors 10a to 10c are photoelectric conversion element consisting of a solar battery, etc., and detect the luminance level in the case respective LEDs for red, green and blue 2a to 2c emit light and convert it into a corresponding voltage value. The converted voltage value is inputted in the light quantity control circuit 11 and compared with reference voltage previously set for the respective LEDs 2a to 2c. In the case the detected value by the photosensors 10a to 10c is lower than the reference voltage, a current flowing in the respective LEDs 2a to 2c is increased so that light quantity is increased to raise the luminance level. In the case it is higher that the reference voltage, on the contrary, the current is decreased to lower the luminance level.
