IPC: G01B11/30
Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain a geometrically desensitized interferometer whose high measuring precision is maintained, which minimizes a ghost image and whose rear reflection to an image device from a diffraction grating is reduced by constituting an optical mechanism so as to deflect a stray light from an incident hole in the image device. SOLUTION: In this geometrically desensitized interferometer GDI, a scanning stage moves a support 52 and an object O, to be measured, perpendicularly to its surface S. A light generator 60, an image device 64 and an optical mechanism 62 are arranged. The optical mechanism 62 contains a linear diffraction grating 70 and a linear diffraction grating 72. The cross-sectional shape of a groove on the diffraction face of the diffraction grating 70 is adjusted, and a desired stray-light reduction effect can be obtained. That is to say, when the wedge shape and the inclination of the diffraction grating 70 are selected properly, a stray light is deflected from a pupil 78 as an incident hole in the image device 64, and, at the same time, it is possible to prevent an average phase offset and a phase offset change on an optimum measuring plane.  Thereby, after an operator places the object O, to be measured, in the region of a maximum interference-fringes contrast, it is not required to rearrange the object again.

Title: Film driving device for camera
Inventor: TAKEMATSU YOSHIYUKI
IPC: G03B17/00
Filed: 1990-09-17
Abstract: PURPOSE:To offer the driving device of simple constitution which is applicable to all cameras without providing any interlocking mechanism between a shutter and a sprocket switch by rewinding a film unless the film is wound in a one- frame winding time. CONSTITUTION:The driving device is equipped with the timer consisting of a capacitor 53 and a CMOS inverter 54. When the film is wound normally by one frame, the charging voltage of the capacitor 53 never exceeds a specific value and the CMOS inverter 54 holds a high voltage. In a state wherein the film is wound to its overall length and the sprocket switch 44 can not be operated, a transistor 55 is still OFF, so the charging voltage of the capacitor 53 exceeds the specific value, so that the output of the CMOS inverter 54 changes from high to low. Thus, the output of the CMOS inverter 54 changes from high to low and a driven circuit moves back to switch a motor feeding circuit from a forward rotating circuit to a reversing circuit. The reversing circuit for the motor 43 is formed. In this case, the motor 43 rotates so as to rewinding the film.

IPC: B23K10/00
Filed: 1988-09-30
Abstract: PURPOSE:To execute a plasma gas flow rate control synchronized with a pulse current value by providing a control means for controlling a gas flow rate for generating plasma in the vicinity of a torch. CONSTITUTION:A plasma exhaust port (nozzle) 4P is opposed onto a weld line of a material to be welded 1, and a gas flow rate controller 5 is attached to a torch. To the torch 4, a pulse current, a plasma generating gas, shielding gas and a control signal transmission cable, and a signal line 10 are led from a power source unit 2. Gas plasma welding which can control a flow rate of gas can control the flow rate of gas for exerting an influence on closing of a key hole, therefore, even if thickness of the material to be welded becomes large, the generation of a blowhole to a dissolving part caused by blowout pressure of gas can be prevented. Also, the gas flow rate is controlled synchronously with a plasma generating pulse current value, therefore, welding for generating no blowhole, etc. can be executed. In such a way, an applied range of plasma key hole welding can be enlarged.

Abstract: PURPOSE: To realize efficient encoding by storing a marker code together with a silence time code, which is obtained by encoding the duration of a silent section, in the case of encoding the silent section in recording and using the marker code to detect the silent section in reproducing. CONSTITUTION: An encoder 2 stores a marker code M, which indicates that frames discriminated as silent are a silent section, and the silence time code, which is obtained by encoding the counted number of silent frames as a duration Tu of the silent section, in a sound code memory 4.

IPC: G09G3/20
Filed: 1990-09-13
Abstract: PURPOSE:To generate no difference in holding characteristics even when a driving waveform is inverted and to uniform the contrast of a screen by varying the potential of a data signal about the nonselection potential of a scanning signal. CONSTITUTION:An electrooptic material 33 is applied selectively with a voltage Va-Vb-Vd when a picture element is ON or Va-Vb+Vd when OFF in a 1st scanning period, and Va'$7-Vb+Vd when the picture element is ON or Va'-Vb+ Vd when OFF in a next scanning period. Then, Va-Vb-Vd=-(Va'-Vb+Vd) and Va-Vb+Vd=-(Va'-Vb-Vd), therefore, Va-Vb=-(Va'-Vb) need to hold as the conditions of data inversion. As for the holding characteristics,it is evi dent from figures (c) - (f) that the data signal varies within a range of Vb+ or -Vd without reference to whether the signal is inverted or not, and the scanning signal is invariably held at a potential Vb the time of a nonselection signal, so voltages applied to nonlinear resistance elements 34a and 34b in a nonselection period are not affected by the data inversion.
