Title: Edge detecting method of dimension measuring instrument
Inventor: OKADA MICHITOSHI
IPC: G01B11/00
Filed: 1995-03-15
Abstract: PURPOSE: To provide an edge detecting method of dimension measuring instrument by which the binarized edge of an object can be detected in a short time without using any large-scale hardware. CONSTITUTION: A dimension measuring instrument measures the dimension of an object to be measured by receiving a light beam from the object by means of a CCD image sensor and binarizing the output signal of the sensor, and then, detecting edges from the binarized signals and measuring the dimension of the object from the edge sections. All picture element data of the output signal of the image sensor which outputs 5,000 picture element data are divided into 10 areas of 500 data each and the leading edge data of each area is extracted and binarized. Then one binary data indicating bright '0' or dark '1' is obtained from each area from the 10 binarized data.  In addition, a leading side area where a bright area and dark area exists adjacently to each other is further divided into a plurality of subareas and narrowing down the subareas in the same way and, finally, picture elements having abnormal binarized values, namely, edges are detected from the output signal of the image sensor.

Title: Thin film transistor matrix array
Inventor: OKABE KAZUYA
IPC: G02F1/136
Filed: 1987-03-11
Abstract: PURPOSE:To improve the yield rate, by making the width of one line of electrode wirings narrower than the width of the line at the other part, at the intersecting part of a gate electrode wiring and a source wiring electrode, and reducing the area of the intersecting part. CONSTITUTION:The width of each line of a gate electrode wiring 12 and a source electrode wiring 13 at the intersecting part is formed so that the width is narrower than the width of a line at the other part. Narrow parts 12a and 13a are formed at the respective wirings. The overlapping part of the wiring 12 and the wiring 13 at the intersecting part is only the overlapping part of the narrow part 12a and the narrow part 13a. Even if a pinhole defect is present in an insulating film 14, the probability that the pinhole is positioned just at the overlapping part of the electrode wirings is 1/16 the probability in a conventional device. Thus the yield rate is improved.

Abstract: PURPOSE:To suck mist at the place near a source before the mist is diffused, even if it is generated, and to increase efficiency for collecting the mist by placing a sucking nozzle at a position opposite to a reflecting surface where a photosensitive material surface receives jet air from an air knife. CONSTITUTION:A sucking means 3 is placed side by side along the slit nozzle 2 of an air knife 1, and a sucking slit 4 provided on the tip of the sucking means 3 is constituted so as to be located in a vicinity where the jet air blown from the slit nozzle 2 hits on a photosensitive material 6.

On the other hand, the sucking slit 4 of the sucking means 3 has width a little longer than that of the slit nozzle 2, and can execute sucking by the blower via a mist separator. Therefore, the pollution of the photosensitive material and the insides of the surrounding machines, caused by the scattered mist, can be prevented.

Abstract: PURPOSE:To obtain the stable cutting plase detection output, by superposing the signal for detection of cutting phase onto the D.C. voltage of the same polarity with the charge signal for printing. CONSTITUTION:By applying alternating voltage 14 to an electrostrictive vibrator 16, the current of ink 6 is cut into regular flying ink dropps 7. When a fixed amount of voltage is applied to a charge electrode 3 from a charge voltage generating circuit 11 synchronizing with the timing when this ink current is cut to ink drops, the cut ink drop is charged with electricity proportioned to the applied voltage. A detection electrode 9 is positioned at a place not disturbing the printing onto the object to be recorded. When a retrieval signal pulse is in accord with the cutting phase, signal is outputted from a detection circuit 13. However, when the cutting phase is not in accord therewith, the phase of the retrieval signal pulse is successively shifted relatively to the phase of alternating voltage.

IPC: H01L39/24
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a mixer having a Josephson junction and increase the reliability by making a critical current value of other elements than the mixer smaller than that of the mixer at the operating temperature of a monolithic high frequency circuit constituted of a superconducting film. SOLUTION: On a MgO bicrystal substrate 11, a YBa2 Cu3 Oy superconducting film is formed by laser ablation. After that, the film is patterned by photolithography. The line width of a Josephson junction section of a mixer 16 expressed by slanted lines in the figure is 10 μm at the narrowest. With other regions than the mixer 16 being masked by a resist, substrates are heat-treated one after another in an active oxygen atmosphere. In this heat treatment, the temperature Tc of oxygen in the film of the mixer 16 not masked by the resist increases to about 90K, and the resist is removed at the same time. By this method, a high frequency circuit can be obtained in which Tc in the mixer region is about 90K and Tc in the other regions than the mixer is about 90K.  When this device is mounted on a refrigerator and is operated at 50K, the mixer having about 90K of Tc exhibits a large critical current value.

Abstract: PURPOSE:To make welding always in the same state possible despite the change in power supply characteristics in a short time by controlling a DC welding power supply in such a way that the difference between the arc electric power rate determined from the electric power at the moment of short circuiting and the electric power at the moment of the arc and the set value thereof is made zero. CONSTITUTION:The arc voltage value VA detected with a voltage detecting circuit 5 and the current value IA detected with a current detecting circuit 7 are converted to respectively to corresponding digital quantities with the circuits 10, 11 of an electric power calculating circuit 8 and these digital quantities are inputted to a circuit 12. The circuit 12 multiplies both and outputs the same to a circuit 14. The circuit 14 compares the set voltage value VL from a circuit 12 and the voltage value VA from the circuit 5 and obtains a switching signal. By this signal, the integrated values corresponding to the two states VA>=VL and VA<VL are selectively outputted as electric power Pa at the moment of the arc and electric power Ps at the moment of short circuiting to a circuit 15. In the circuit 15, arc electric power rate zeta=Pa/(Ps+Pa) is calculated, and a comparator 17 compares this with set arc power rate zeta, and controls a DC welding power supply 6 so that these attain zeta-zeta'=0.
