IPC: H04J13/00
Filed: 1982-04-30
Abstract: PURPOSE:To decrease greatly the time required for the set-up of synchronization, by providing plural code series generating means which shift the phase of the code series and a selecting means which selects each code series obtained from said code series generating means. CONSTITUTION:A specific output is selected from an n-stage shift register 20, and an output is obtained from exclusive OR circuits 22 and 23, respectively. In such a way, three sets of code outputs having about 1/3 phase shift to each other are obtained to a cycle of a pseudo noise code and given to a data selector 24. One of these three sets of codes is delivered via a 1/2-bit shift register 11. These codes disperse adversely receiving signals RXSS through three correlators 1-3 and detect correlations through envelope curve wave detectors 4- 6. A synchronization detecting circuit 19 applies the correlated and detected signal to the selector 24 and has a control to select the code corresponding to said signal. When the synchronization is detected, a clock controlling circuit 18 is controlled to discontinue the searching. Thus a synchronous state is held.

Title: Volume multiple holography device
Inventor: MORINAKA AKIRA
IPC: G03H1/26
Filed: 1991-04-05
Abstract: PURPOSE:To record and reproduce the volume multiple holography at a high speed without adjusting an optical system and to improve the accuracy of the optical axis by arraying many laser light sources. CONSTITUTION:The luminous flux from a laser group 11 consisting of many laser light sources is split by optical systems 13 and 15 into plural pieces of luminous flux, which are guided to a storage element 12 to interfere with each other. At this time, part of luminous flux emitted at a different position of the laser group 11 is scattered by mutually different storage patterns 16 and then made incident on different positions of the storage element 12, so that the light is recorded as interference fringes of other parts. Namely, the light sources in the laser group are changed without the rotary movement of the storage element 12 nor the mechanical movement of the optical system, thereby obtaining the volume holography. In this case, a surface light emission laser diode array is used preferably as the laser group 11 and this laser diode array is formed by stacking light emission joint parts on, for example, a GaAlAs substrate and then machining the light emission joint parts into a columnar set by etching.

Title: Cevter pressure adjusting device
Inventor: IWASAKI HIDEKI
IPC: B24B41/06
Filed: 1990-03-22
Abstract: PURPOSE:To adjust the center pressure during working to a magnitude most suitable at every work by detecting the amount of relative displacement of a mobile center with a sensor position detecting means and automatically controlling an oil pressure means so that this amount goes to zero. CONSTITUTION:At the time of working, a work W receives a pressure intersected orthogonally with the axial line, and a reaction in the axial direction acts on a mobile center 5 and the mobile center 5 is relatively displaced minutely. A center displacement amount calculating part 19 detects the amount of displacement; and if its value is not zero, a displacement division is discriminated. The present speed of revolution of an oil pressure pump 11 is calculated by the speed of revolution of a pump calculating part 21, and an arithmetic part 22 calculates an increased speed of revolution corresponding to the displacement division and adds it to the speed of revolution of the pump to set the target speed of revolution. An operation part 23 controls an oil pressure device so that the speed of revolution of the pump 11 coincides with the target speed of revolution. Thus, the pressure of the mobile center during working is most suitably adjusted.

Filed: 1987-03-26
Abstract: PURPOSE:To prevent the generation of the change in a pattern shape during measurement, by scanning a position, which is separated from the end of a pattern by the magnitude of electron beam, by the electron beam. CONSTITUTION:The position 3 separated by about 0.5mum from the end of the org. resist pattern of a silicon substrate 1 is scanned by electron beam 4 and the reflected electron 6 is detected by a detector 5 and the output wave form thereof is accumulated on the memory of a computer. The result thereof is operated and the line width of the pattern 2 is measured from the two points becoming the max. and min. values of signal intensity. When measurement is repeated at the same position by this method, a change is eliminated in the line width measured value depending on the irradiation time of the electron beam. By this constitution, the surface contamination of the pattern is prevented by the action of the incident electron beam and the shape of the pattern can be measured without being changed.
