Abstract: PURPOSE:To stabilize focus control by intervening a hotogram element having a non-hologram area in a part between lenses and receiving reflected light beams in a photodetector which has divided them when by recording/reproducing light beams an optical storage medium are irradiated through the collimator lens and the objective lens. CONSTITUTION:Laser beams from a semiconductor laser 1 giving coherent beams are turned into parallel beams in the collimator lens 2, and made incident on the objective lens 3, by output light beams from here, an optical disk 4 are irradiated. In such a constitution, the diffraction grating hologram element 6 which has generated the non-hologram area or different holograms in a part is interposed between the lenses 2 and 3. Thus, zero-order transmitted light beams are converged into the disk 4 on the outgoing path, and the zero-order transmitted light on the incoming path reflected from there and an astigmatically reproduced image, and their conjugate images, namely the two wavefronts 71 and 72, are generated on-axis and off-axis respectively. Next, the four-division photodetector 5 receives them, and a stable focus control signal can be obtained even if wavelength fluctuation occurs in the laser.

Filed: 1981-05-29
Abstract: PURPOSE: To reduce the time for attaining a required degree of vacuum of a vacuum treating chamber, by providing a by-pass circuit for using a main pump at an initial evacuating stage and using both main and booster vacuum pumps when approaching to the required degree of vacuum.  
     CONSTITUTION: In an apparatus by which a plastic molded product, e.g., vinyl chloride resin film, is treated by plasma in a vacuum chamber, at initial stage evacuation is carried out by a pump 4 through a by-pass circuit 22 by opening a valve 23 in the circuit 22. When a degree of vacuum of the chamber 1 approaches to the required value, a booster pump 21 begins to operate and the valve 23 in the by-pass circuit 22 is closed.

Filed: 1987-04-03
Abstract: PURPOSE:To eliminate complicated manual operation and response operation on a caller side and a caller side, by providing a control means which selects a device receiving incoming call from plural terminal equipments corresponding to a dial signal transmitted from the caller side after connecting a line. CONSTITUTION:An incoming terminal is designated by transmitting a dial tone by dialing (#1-#4) and a (*) behind a telephone number from the caller side. When a call signal is detected by a call signal detection circuit 3, a DTMF detection circuit 5 is connected to the line. Thereby, the DTMF detection circuit 5 forms a DC loop, and the line is connected. And when the DTMF detection circuit 5 detects the receiption of the tone (#), a numerical tone is detected, and the bell of a telephone set corresponding to a detected number tone is rung, then, the operator of the telephone set is called. Thus, since the incoming device can be designated by transmitting the dial tone from the caller side, a targeted operator can be called immediately in the case of communication, and also, it is possible to make the complicated manual operation of the operator on the incoming side unnecessary in the case of facsimile communication.
