Patent JP-H05316692-A (JP)
Title: Actuator fitted with thrust sensor
Inventor: KAIDO TSUTOMU
IPC: H02K11/00
Filed: 1992-05-11
Abstract: PURPOSE:To remove the increase of the friction, the inertia moment, and the frame size by the addition of thrust detection and remove the restriction on temperature in use, etc., by detecting and controlling the generated thrust by the physical change related to the generated thrust, with one part, which constitutes an actuator, as a detection part. CONSTITUTION:When thrust occurs in a rotor 1, in tees, tension adds to 9A and pressure to 10A, and the magnetic induction ratio of the non-oriented electromagnetic steel plate of a used material changes, and in the section 9A, the output of winding 7A for detection of magnetic flux increases, and in the section 10A, it decreases. Here, the change by the stress is accelerated by connecting the winding 7A for detection of magnetic flux in reverse direction, between the section 9A and the section 10A, and the change of output of the winding 7A for detection of magnetic flux is proportioned to the stress 8A falling on the tees. Accordingly, the output of the winding 7A for detection of magnetic flux is output in proportion to the thrust value generated in the rotor 1. In this way, the thrust of an actuator is detected by the change of inner stress, so it becomes simple in structure.

Title: Electronic device
Inventor: ISHII MASAHIRO
IPC: H02P7/06
Filed: 1993-05-20
Abstract: PURPOSE:To achieve low level noise and vibration by providing a circuit that, after a cooling fan has started at a voltage required for its start-up, lowers the voltage to a level required for the normal rotation of the cooling fan. CONSTITUTION:When power is supplied, a voltage is applied to the base of a transistor 202 through a capacitor 209, and the transistor 202 is turned on. When the transistor 202 is turned on, another transistor 201 is turned on as well, and a cooling fan 210 is supplied with power of starting voltage of 5V through the transistor 201. A resistor 204 and the capacitor 209 forms an integrating circuit, and the voltage applied to the base of the transistor 202 is lowered with time until the transistor 202 is turned off. When the transistor 202 is turned off, the transistor 201 is turned off as well, and the voltage is applied to the cooling fan 210 through a resistor 206. This makes it possible to control the speed of cooling fan 210 rotation, and thus reduce noise and vibration to any desired level.

Title: Optical pickup
Inventor: NAKAMURA TOORU
IPC: G11B11/18
Filed: 1979-09-14
Abstract: PURPOSE:To reproduce record on a disk with simple constitution without contact by causing light, focused via a condenser lens, to strike a photodetector and then by detecting the movement of the modulated groove wall of a record disk as a shift in focus to obtain an audio output. CONSTITUTION:Since beam focused via condenser lens 5 is slantingly incident to modulated-groove wall surface 6, the beam incident to photodetector 7 varies with the movement of modulated-groove wall surface 6, i.e. the reflecting surface. As modulated-groove wall surface 6 moves as shown by (a)-(c), a light spot on photodetector 7 shifts in position. At this time, outputs of two-split photodetector 7 are passed through substracting circuit 8 to find their difference voltage, which corresponds to the displacement of record modulated-groove wall surface 6 by a sound signal. For this purpose, this difference voltage is passed through differentiating circuit 9 to obtain a speed voltage, i.e. sound signal. This simple constitution provides the contactless reproduction of a record disk.

Filed: 1985-05-30
Abstract: PURPOSE:To attain an accurate and quick track jump action by switching the acceleration pulse signal to the deceleration signal based on the result of comparison between a tracking error signal and the divided peak value of said error signal. CONSTITUTION:The tracking error detecting signal detected by a tracking error detecting circuit 6 is applied to comparators 14 and 15 and the positive and negative peak holding circuits 10 and 11 respectively. The circuits 10 and 11 store the positive and negative peak values of the tracking error signal respectively during a track jump with an indication given from a controller 17. While the circuits 12 and 13 divide the positive and negative peak values respectively and these divided values are compared with the tracking error signal by the comparators 14 and 15 respectively. A track jump pulse generating circuit 16 performs the rough retrieval with an indication of the controller 17. Then the acceleration pulse is switched to the deceleration pulse by the output of the comparator 14 or 15. Thus a track jump pulse including positive and negative pulses is delivered.
