Title: Oblique incidence interferometer device
Inventor: SUZUKI MASANE
IPC: G01B9/02
Filed: 1986-01-31
Abstract: PURPOSE:To measure an object surface by forming the 2nd diffraction grating by holography and measuring the sample by using the 2nd formed diffraction grating. CONSTITUTION:Laser light emitted by a laser oscillator 1 is diverged by a diverging lens 2. Then the laser light after passing through a pinhole 10 and being reflected by a reflecting mirror 11 is collimated by a collimator lens 3 into parallel luminous flux. The 1st diffraction grating 4 diffracts this parallel laser light. A mount table 5 is movable in three dimensions. The 2nd diffraction grating 6 consists of a holographic grating and the flatness of the sample is inspected accurately by properties characteristic to the holography that the holographic grating itself has even if the collimator lens 3 and the 1st diffraction grating 4 are manufactured with slightly low precision. Consequently, the flatness of the sample is measured accurately.

Filed: 1993-02-09
Abstract: PURPOSE:To output a backup signal at the time when a demodulating signal does not reach a prescribed level by switching to a main signal and a backup signal in accordance with a demodulating signal level by an output of an amplifier. CONSTITUTION:In the case an optical signal is not inputted, a signal is not outputted either from a photodiode 9, therefore, a voltage level after passing through a detector 21 becomes an L level. Accordingly, a comparator 17 detects abnormality, transistor 18 is turned on, and a relay 11 is energized. As a result, from the signal output 15, a backup signal inputted from a coaxial signal input 19 is outputted. In the case there is no input to an optical transmitter 6 due to a fact that an input cable is detached, etc., although a optical signal is inputted, and even in the case of a fault of a high frequency signal amplifier 14, a voltage level of an output of the detector becomes L, and finally, the relay 11 is energized and the backup signal is outputted automatically from the output 15. In such a way, a stagnant wave caused by a fault, etc., can also be backed up as a system.

Title: Fuel injection valve for diesel engine
Inventor: KAMIYA MAMORU
IPC: F02M45/08
Filed: 1983-02-12
Abstract: PURPOSE:To prolong fuel injection time without reducing injection pressure particularly in low revolution and low loading state of an engine, by jetting-out fuel in two stages. CONSTITUTION:The first needle 8 and the second needle 9 are inserted into a nozzle body 1. The second needle 9 is inserted in movable ways into the first needle 8. Since the spring force of the second pressure spring 20 is made relatively smaller than the spring force of the first pressure spring 14, the second needle 9 lifts earlier when an equal fuel pressure is applied onto the first needle 8 and the second needle 9. Therefore, fuel is jetted-out from the second injection hole 18, passing through the first injection hole 6, and then the first needle 8 lifts, and all the necessary amount of fuel is jetted-out from the first injection hole 6.

Filed: 1982-02-15
Abstract: PURPOSE:To obtain a stereoscopic color TV picture of high quality, by switching a shutter with the light given from a specific fluorescent matter of a CRT and synchronously with the right and left eye information which change for each field. CONSTITUTION:The output of a video signal 3 is fed to a vertical synchronizing signal separator 4 and a video signal processor 6. The synchronizing pulse is produced from a synchronizing pulse generator 5 on the basis of the vertical synchronizing signal extracted through separation 4 and then fed to the processor 6. The processor 6 sets the beam current of a CRT at the maximum level when a pulse is fed from the generator 5. When the generator 5 delivers a pulse while the scanning beam is scanning the specific part of a fluorescent matter, a specific spectrum has intensive light emission. This emitted light is received 9 and converted into an electric signal to be amplified. Then a pulse is generated from a shutter switching pulse generator 11. Thus a shutter 12 is switched for each field and opened for right and left eyes respectively.
