Title: Laser wavelength detector
Inventor: SHIMADA YASUHIRO
IPC: H01L21/66
Filed: 1988-05-16
Abstract: PURPOSE:To detect the oscillation wavelength of a laser with good accuracy and reproducibility by superposing the transmission peaks of one or plural Fabry-Perot etalons and providing photodetector near to the focal surface of a condenser lens which condenses the transmitted light. CONSTITUTION:The luminous flux 11 of KrF excimer laser light is introduced from an incident window 7 and is transmitted through the Fabry Perot (F-P) etalons 1, 2. The transmitted laser light is subjected to selection of only the laser light parallel with the optical axis of this detector by the condenser lens 3 and a pinhole 4 and the selected light is made incident to the photodetector 5. The coincidence of the centers of the wavelength of the transmission peaks coupling the F-P etalons 1, 2 and the oscillation wavelength of the KrF excimer laser is detected by the max. response of the photodetector 5. Since the F-P etalons 1, 2 are provided in a hermetic container 6, the influence of a change in the pressure and temp. of the atmosphere is eliminated. The laser wavelength is thereby detected with the god accuracy and reproducibility.

IPC: C02F3/34
Filed: 1986-05-23
Abstract: PURPOSE:To obtain a substantial effective volume for reaction by housing granular sticking carriers to be stuck with microorganisms into a reactor body and constituting said sticking carriers of plural kinds of carriers which are different in specific gravity and/or grain size. CONSTITUTION:The granular sticking carriers 9 to be stuck with the mi croorganisms are housed into the reactor body 8 and the sticking carriers 9 are constituted of plural kinds of the carriers (a), (b) which are different in the specific gravity and/or grain size. The carriers having the larger specific gravity or the smaller grain sizes form a lower fluidized bed if the sticking carriers are maintained in the fluidized state. On the other hand, the carriers having the smaller specific gravity or the larger grain size form the upper fluidized bed. As a result, the region where the vortexes to decrease the amt. of the living things to be held in the reactor is decreased and the permissible load is increased as compared to the fluidized bed consisting of one kind of the carrier intended only for the sticking of the biological membrane.

Abstract: PURPOSE:To make high speed and high precision swing processing by judging whether the actual position of a processing electrode becomes identical to the command value for the processing depth in each of the coordinates of the swinging plane, and conducting processing while the servo is changed over according to the identicalness region or the out-of-identicalness region. CONSTITUTION:The actual amount of progress in processing is sensed by a sensor 5, and judgement is made whether the tip of a processing electrode 1 has, even only once, reached a command value 18 to command the depth of swing processing in one region of the sensing region 90. If no, the processing is executed in the free mode which involves retreat of the processing electrode 1. If yes, storing in memory is made about in which region as divided the tip of the processing electrode 1 has reached the command value 18. In the case of the region where the tip of the processing electrode 1 during swing processing has not even once reached the command value, changing-over is made into the fixed mode which suits high precision processing; in case the command value 18 is reached even only once, judgement is made about whether the memory action is applied to the whole regions, and if yes, the series of processing works shall be ended.

Filed: 1986-05-23
Abstract: PURPOSE:To shorten the processing time as the whole by automatically reading contents of a FIFO memory into a private register when it is unnecessary to hold contents of the private register during subtraction in an image converting processor. CONSTITUTION:When an image converting processor 7 outputs a response signal *ACK to reset a D flip flop 10 during a series of processings, a Q output signal *AUTO goes to the low level.

IPC: F16F15/10
Filed: 1980-08-26
Abstract: PURPOSE: To prevent damage to a centrifugal by disposing on a support member on which a bearing for supporting a rotary shaft is mounted a vibration detector for detecting vibrations of the support member so that an electric motor may be stopped when vibrations of an amplitude greater than a predetermined level are detected.  
     CONSTITUTION: A detector 21 is mounted on a support bracket 22 which in turn is mounted on a table 1. The detector 21 is located in an opposed, radially spaced relationship from an outer periphery of a support member 2 and serves to detect an amplitude of vibrations by detecting displacements of the support member 2 relative to the table 1 to provide an electric signal corresponding thereto. This vibration detector 21 may be a suitable detector such as, for example, a detector of an eddy- current loss type. An amplifier 23 amplifies a signal received from the vibration detector 21 and provides an output signal if the amplitude detected is greater than a preset displacement value. An output signal of the amplifier 23 activates a controller so that an electric motor 6 is stopped thereby.
