Title: Track shift detector
Inventor: DAIMON MASAHIRO
IPC: G11B7/09
Filed: 1983-04-21
Abstract: PURPOSE:To detect an accurate track shift by providing a switching circuit, a peak detecting circuit and a holding circuit for the electric output signal given from a photodetector which detects the reflected light from two secondary spots. CONSTITUTION:In order to obtain a correct track shift signal, it is just needed to detect instantly a state where no effect of output variance of a light source 1 is produced and a photodetector 8 receives no effect of a recording pit. In other words, a correct track shift signal is obtained by giving the differential amplification to the outputs E1 and E2 of photodetectors 8 and 10. The output E1 is obtained by turning on a switching circuit when the output of the light source 1 is set a reproduction level (d). Then (e) is obtained by detecting and holding the peak, and the value very close to E1 is obtained. In the same way, the output E2 is obtained by turning on a switching circuit 22b when the light source 1 is set at a reproduction level. Thus it is possible to obtain a correct track shift signal by giving the differential amplification to the signal that was held by holding circuits 24a and 24b.

Filed: 1980-05-29
Abstract: PURPOSE:To perform mutual locking effectively by locking an avalanche diode having unstable frequency by the externally synchronized optical pulse signal with a constant period, taking out a stable output, and applying its electrical output to a laser. CONSTITUTION:The semiconductor laser 2 is connected to the output side of a T branch 1, and a DC bias in the vicinity of an oscillating threshold value and a high frequency input are applied.

Title: Electric fan
Inventor: SHIMOJIMA FUKUMI
IPC: F04D29/34
Filed: 1978-06-14
Abstract: PURPOSE: To simplify conservation and inspection and make the device compact by supporting an outer rotor by means of an elastic body provided on an impeller.  
     CONSTITUTION: Ring-shaped projection 11 and conical projection 13 respectively of impeller 3 and outer rotor 2 are engaged with tapers 12 and 14, and thereby play in the radial direction is eliminated. At the same time, inward projection 8 of elastic body 5 comes into contact with conical projection 13 of outer rotor 2 and further pushes it to the motor side by resisting its elastic force. As a result, when outward projection 7 passes hole 10 of outer rotor 2, it is pushed inward, and after passing, it places itself outward by its elastic force and maintains the motion of impeller 3 in the axial direction. When impeller 3 is removed, push elastic body 5 inward from notch 9 of boss 4 and disengage the outward project from hole 10. The elastic force of inward projection 8 operates in the direction to separate impeller 3 from the outer rotor. Thus, it is possible to simplify conservation and inspection and to make the device compact.
