Title: Optical pickup device
Inventor: YAMANAKA YUTAKA
IPC: G11B7/125
Filed: 1988-06-29
Abstract: PURPOSE:To eliminate the need of a precise control for a distance between the end surface of a semiconductor laser and a recording medium by providing an optical element for rotating polarized light so that the polarized light of returning light is orthogonal to the polarized light of outgoing light of the laser. CONSTITUTION:The semiconductor laser 2 to be used is varied discontinuously in its optical output by an injection current value, and the injection current value is also varied by returning light from the exterior. That is, the injection current of the semiconductor laser 2 is set in the middle of an injection current value range which is varied in accordance with a change of the quantity of the returning light due to the change of reflectance of the recording medium 4, so that approximately two value light of a low output and a high output is outputted by the semiconductor laser 2. In this case, the optical element (1/4 wavelength plate) 5 for rotating the polarized light is provided in an optical system for returning reflected light from a converging point on the recording medium 4 to the semiconductor laser 2, so that the polarized light which is orthogonal to the polarized light of the outgoing light from the semiconductor laser 2is returned to the semiconductor laser 2. By this method, since no interference is generated between the returning light and the outgoing light, the injection current value is not changed by a returning light phase, thus eliminating the need for controlling the distance between the end surface of the laser and the recording medium.

Title: Automatic closing gear for ventilating window
Inventor: YAMADA YOSHIHARU
IPC: F24F7/02
Filed: 1980-11-14
Abstract: PURPOSE: To obtain the captioned gear which is simple in structure and permanently usable without power being supplied by a structure wherein two semi- circular lid plates so constituted to be supported rotatably in opposite direction to each other about the axis normal to the chord of semi-circle respectively by means of a diaphragm and return springs are provided in a pent-roof plate and a wire-meshed perforated ventilating tube.  
     CONSTITUTION: When indoor temperature rises the diaphragm 13 expands to push up a mobile plate 18 and a pusher 20. When the indoor temperature exceeds the fixed temperature, the pusher 20 contacts with and pushes up slant faces 10 and said pushing-up force excels the resultant force of the holding force of the edges of the slant faces 10 of the foots 9b of the mounting bodies 9 and of the reaction force of the return springs 12 to rotate the mounting bodies 9, resulting in opening the lid plates 11. Consequently, the ventilating tube (not shown) is cleared to allow the air pass therethrough. When the indoor temperature lowers and the diaphragm 13 contracts, the lid plates 11 are brought back to their original places by the force of the return springs 12, resulting in closing the ventilating tube.

Title: Dynamic focus circuit
Inventor: KIMURA TOMOHIRO
IPC: H04N3/26
Filed: 1993-06-04
Abstract: PURPOSE:To provide a dynamic focus circuit to make focus adjustment very easy. CONSTITUTION:The component of the vertical period of correction waveform is transmitted to the secondary side of a transformer 22 by, for instance, a pulse such as a clamp pulse inserted into a horizontal retrace line period and so on. This is rectified by a rectification circuit 220, and the correction component of a vertical period is regenerated at a medium voltage side. Dynamic focus waveform S24 is obtained by clamping the correction waveform of a horizontal period transmitted by another transformer 21 at the potential of the correction component of the vertical period by a clamp circuit 210. This dynamic focus signal is clamped absolutely on direct current potential (static focus potential) obtained by adjusting medium voltage. When the static focus potential is kept at the focus potential of the center of a screen, the focus potential of the center of the screen never changes in a direct-current-like way, and is kept constant even when the amplitude of the dynamic focus waveform is adjusted, and the focus adjustment can be made very easy.
