Title: Orientation device of wafer
Inventor: NINOMIYA MASAHARU
IPC: G05D3/12
Filed: 1984-08-08
Abstract: PURPOSE:To perform orientation of any wafers with different diameters without adjustment and contact with periphery thereof by a method wherein peripheral plane of wafer is irradiated with the light flux from a projector to change the light quantity entering into a light receiver by means of changing the reflecting directions corresponding to the angle of optical axis meeting the peripheral plane of wafer. CONSTITUTION:A projector 8 projects light flux into an almost central point on almost level surface of a wafer 2. Then the light flux hitting the peripheral plane 15 through a halfmirror 9 is reflected by the plane 15 back to the mirror 9 by which the light flux is further reflected in a light receiver 10. At this time, a motor 16 is driven to make a controller 17 process a received light quantity related to the rotating angle for detecting the relation between the direction of orientation flat and the rotating angle of motor 16 to be stopped at any specified rotating angle. Now assuming the applicable light flux to be parallel beams, any wafer with different nominal dimention of diameter may be assured of equivalent light quantity received without any adjustment or alteration of mechanism at all. Besides, the orientation flat for peripheral plane 15 may be detected with no contact therewith by means of utilizing the light flux.

Title: Horizontal afc circuit
Inventor: KUMAMOTO SHIGEMI
IPC: H04N5/12
Filed: 1978-12-29
Abstract: PURPOSE: To prevent interference between fly-back pulses and horizontal synchronizing signals by connecting a diode to the capacitor of the saw tooth wave voltage supply side.  
     CONSTITUTION: A horizontal AFC circuit is constituted by connecting newly a series circuit of capacitor 18 and diode 19 in parallel to diode 6. By this constitution, interference components of a saw tooth wave appearing at point A are reduced by forward drop voltage components of diode 19, and the trailing edge of the horizontal synchronizing signal at point A becomes sharp. Consequently, the waveform of burst gate pulses at point B obtained by differentiating the signal by a differentiating circuit consisting of capacitor 20 and coil 21 has a large amplitude and a narrow pulse width, so that the burst signal can be extracted accurately. Further, since the circuit which makes the trailing edge of the horizontal synchronizing signal sharp can be constituted only by providing one diode, the bad influence upon the horizontal synchronizing signal can be prevented with the simple constitution.

Title: Variable gain amplifier
Inventor: SHIMABUKURO TOMOYORI
IPC: H03G3/12
Filed: 1980-11-25
Abstract: PURPOSE:To reduce the residual noise and the distortion, by flowing currents of the same magnitude and directions opposite to each other to one resistance of a three-terminal variable resistor, which is a reference resistance of a voltage- current converting circuit, and the other resistance which is a reference resistance of a current-voltage converting circuit. CONSTITUTION:A signal voltage supplied to an input terminal 11 is converted to a current i3 proportional to 1/R5 by a resistance R5 and is outputted to variable current source terminals (C) of current control circuits 12 and 13, and simultaneously, the current i3 is converted to a current i4, which has the same magnitude as the current i3 and has the direction opposite to that of the current i3, and is outputted from variable current output terminals (d) by current control circuits 12 and 13. Since the current i4 is flowed to a resistance R6, an output voltage i4R6 is generated in an output terminal 15. When the voltage of the resistance R6 is set to 0, the voltage gain becomes 0, and the current i3 is equal to the current i4 approximately to set the current, which is flowed to a contact resistance R4 of a slider, to 0 through a current i3-i4 is flowed to the contact R4 of the slider of a three-terminal variable resistor 14, and thus, the residual noise and distortion are eliminated.

Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To detect local small extension by laying optical fibers on a structure by an arbitrary number of returns in an arbitrary interval. SOLUTION: An optical fiber sensor 10 is laid with optical fiber 11 on a tunnel wall by an arbitrary number of turnarounds in an arbitrary interval. Here, the optical fiber 11 is laid on a belt shape steel plate 12 of which width is determined to have marging for the radius of curvature of the optical fiber, so as not to affect the distortion measurement value by the attenuation of transmitting light quantity due to the bend of the optical fiber 11. By this, when the tunnel inner wall extends or contracts, the optical fiber 11 of the optical fiber sensor 10 extends or contracts according to this. The extension and contraction of this optical fiber 11 equivalently extends or contracts to the optical fiber 11 corresponding to a total of 5 pieces of fibers of 2 m for every 40 cm interval laid in the interval L of a unit length.  This is applicable not only to distortion of tunnel inner wall but also to the measurement of deformation of various structure, for example, a structure having a curvature surface.
