Title: Mounting method for photocoupler
Inventor: TOMONO AKIRA
IPC: G02B6/43
Filed: 1981-08-19
Abstract: PURPOSE:To improve the light coupling efficiency and to reduce the mutual interference even if a plurality of photocouplers are mounted in a container by mounting the photocoupler in a cavity. CONSTITUTION:Numerals 1, 2 designate photocouplers, 12 a light emitting device such as GaAs LED or the like, which is mounted on the bottom of a cavity 11, a 13 (13-1, 13-2) switch chips such as P-N-P-N switch or transistor, which are mounted to cover the entirety so as not to leak the light of the unit upwardly. Numeral 14 designates a transparent substance filled in the cavity such as, for example, photocoupling resin such as silicon resin. When the device 12-1 is emitted, part of the light is emitted directly to switching elements 16-1, 16-2 and part of the light is reflected on the wall to the elements 16-1, 16-2, thereby improving the coupling efficiency. Since the light is reflected on the wall, the light is not transmitted to the other adjoining cavity.

Title: Rotary vane system pump
Inventor: YUMIYAMA SHIGERU
IPC: F04C29/06
Filed: 1985-06-17
Abstract: PURPOSE:To prevent sliding sound of a vane from being transmitted to the outside by forming a moat-like groove between the inner and outer peripheries of a cylindrical center case to enclose this groove with a side cover while discharging the discharge medium of a pump through the groove. CONSTITUTION:A moat-like groove is formed between the inner and outer peripheries of a cylindrical center case 2 of a vane type vacuum pump and enclosed with a side cover 1 to form an enclosed chamber 9. Gas discharged from a discharge port 10 passes through the enclosed chamber 9 to flow into a drain port 11 so that the discharged gas is silenced in the enclosed chamber 9. Also, the enclosed chamber 9 is formed to surround a operating space 12 so that the sliding sound of the vane 7 produced by the running of the pump is prevented from being transmitted to the outside.

Title: Optical communication system
Inventor: GOTO MASAYUKI
IPC: H04B10/564
Filed: 1980-09-17
Abstract: PURPOSE:To make long the life of light emitting elemets, by controlling an optical output of the light emitting elements according to the loss, in a bidirectional communication system. CONSTITUTION:An optical level incident to a photo detector 6 is discriminated for more or less than an arbitrary optical level by a reception level discrimination circuit 20. The discriminated output is synthesized into a main signal at a light emitting element drive circuit 12 and transmitted to an optical transmission line 14 at a light emitting element 13. The transmitted signal is converted into an electric signal at a photo detector 15 and amplified at an amplifier 16. A discriminating signal synthesized and transmitted to the main signal is detected at a discrimination signal detection circuit 21 from the signal. This discrimination signal controls a light emitting element drive circuit 3, allowing to control so that an optical level incident to the photo detector 6 can be constant by the output of the detector 4. This is the same for the method controlling the light emitting element 13 so that the optical level incident to the photodetector can be constant. Thus, the light emitting output of the light emitting element can remarkably be reduced and life of the light emitting element can be extended.

IPC: H01J37/304
Filed: 1980-09-19
Abstract: PURPOSE:To control the focus of an electron beam accurately by applying the beam excessively on a prescribed part of a resist film formed on a surface to be exposed, prior to the electron-beam exposure, to form a recessed part thereon and by using this recessed part as a mark for detecting a reflected electron. CONSTITUTION:The resist film 2 is formed on a substrate 1 provided with an oxidized film and a wiring layer. On to the prescribed part of the resist film 2 the electron beam is applied excessively beyond the proper exposure amount of a resist, whereby the concave part 4 is formed. This recessed part 4 is used as the mark for detecting reflected beams. Next, when scanning is conducted with an electron beam 3, the amount of the reflected electron decreases at the recessed part 4 and thus a reflected-electron signal 5 and a differential waveform 6 thereof are obtained. When the electron beam is not focused, in this case, the waveform thereof takes a dull form b' and the differential waveform thereof also turns to be dull as shown by c'. Accordingly, by adjusting exciting current so that the difference between the maximum and minimum values of the differential waveform be maximum, the control of the focus can be performed accurately and easily.

Abstract: PURPOSE:To attain the line connection in the same node and among different nodes by providing a time slot conversion circuit. CONSTITUTION:A reception signal 11 from a loop time division multiplex transmission line is inputted to a selection circuit 13 having an inserting function to realize a line passing through a multiplexer 10.
