Title: Solid-state image pickup device
Inventor: NAKAJIMA TAKATSUGU
IPC: H04N5/369
Filed: 1990-09-11
Abstract: PURPOSE:To realize an automatic exposure regulation function through the use of an inexpensive manual iris lens by controlling a charge storage period of the CCD in the unit of a time equivalent to one period of a horizontal synchronizing signal when a final sweepout timing of a stored charge stays within a video signal period and controlling the charge storage period of the CCD continuously when the final sweepout timing of the stored charge resides in a vertical blanking period. CONSTITUTION:The charge storage period of the CCD 11 is controlled in the unit of a time equivalent to one period of a horizontal synchronizing signal when a final reset pulse SUB stays in a video signal period, that is, in a low speed shutter mode where an object is dark and a low output level of the CCD 11 is detected by a detection circuit 15, and the charge storage period of the CCD 11 is controlled continuously when the final reset pulse SUB resides in a vertical blanking period, that is, in a high speed shutter mode where an object is bright and a high output level of the CCD 11 is detected by the detection circuit 15. Thus, the charge storage period of the CCD is fine-regulated continuously in the high speed shutter mode where the regulation of the charge storage period in the unit of 1H is not practical for the purpose.

Abstract: PURPOSE:To obtain a uniform depressing force by a method wherein a thermal head holding mechanism has a center part single point holding form, a head depressing lever is pressed against a platen roller by a cam action, and this pressing force is made to act through a depressing spring. CONSTITUTION:In a support board 8 of a thermal head holding mechanism 10, a flat part 8'' securely pressed by a spring 24 serves as an arm for holding a thermal head 50. The thermal head 50 is fixed on one surface of the thermal head support board 8 at the center part of the rear end surface thereof. The other surface is rotatably and elastically supported at a single point axially by a head journal 9 passing through an elliptical opening 8'''. With the issuance of a printing signal, a head depressing cam 12 is rotated by a motor 16 to press down a depressing lever 10', and the thermal head 50 is depressed on a platen roller through a head depressing spring. In this state, a microswitch 28 is actuated by a switch cam 29, whereby the rotation of the depressing cam 12 is brought to a stop, and a maximum diameter part comes into contact with the surface of a tip end part 10'B of the depressing lever. Therefore, a depressing force to the thermal head can be made uniform against the platen roller.

Title: Exposure control method for camera
Inventor: KAGECHIKA TAKASHI
IPC: G03B7/087
Filed: 1989-09-14
Abstract: PURPOSE:To obtain a preferable picture when a background is dark at the time of taking the photograph of a person as an object with high brightness by controlling an exposure controller so as to set an exposure quantity wherein a range-found object does not fall into over-exposure when the brightness of the range-found object is higher than a prescribed value. CONSTITUTION:The exposure controller is controlled so as to set the exposure quantity wherein the range-found object does not fall into over-exposure. Name ly, since the light receiving angle of a range-finding photodetector 1 is narrower than a range-finding photodetector 21 and the photoelectric output changes according to the brightness of the range-found object, whether or not the bright ness of the range-found object is higher than the prescribed value can be detected. When the brightness of the range-found object is high than the pre scribed value, the exposure controller is controlled so as to set the exposure quantity wherein the range-found object does not fall into over-exposure. Thus, when the brightness of the object is high and the background is dark, the object is prevented from falling into over-exposure, therefore, a preferable picture can be obtained.

Title: Voltage-type inverter
Inventor: SHINOHARA KATSUJI
IPC: H02M7/757
Filed: 1990-09-10
Abstract: PURPOSE:To reduce the filter capacity of an AC input side by a method wherein bidirectional switching devices are employed in a converter module and the firing angles of the switching devices are controlled. CONSTITUTION:A converter module 3 is composed of bidirectional switching devices 301. The firing angles of the converter module 3 are so controlled as to reduce the filter capacity of an AC input side. In order to reduce the filter capacity of the AC input side, it is effective to control the firing angles so as to reduce ripples of currents inputted to the converter module 3. As a firing angle control method, for instance, it is recommended to perform PWM control in such a manner that the switching devices 301 are turned on not only during a closing period while an electric angle is 120 deg. but also during a period while the electric angle is 5.80 deg.-8.72 deg. before and after the closing period. With this constitution, the filter capacity of the AC input side can be reduced.

Title: Inspection device
Inventor: ISHIKAWA SEIJI
IPC: H01L21/66
Filed: 1989-09-18
Abstract: PURPOSE:To eliminate the need for performing coordinates conversion and reduce labor for data analysis by setting a standard coordinates system for a wafer, providing a conversion part for converting between the standard coordinates system for each inspection device and the one which is peculiar to each inspection device, or standardizing inspection device standard for achieving inspection and analysis of all inspection devices being based on the standard coordinates system. CONSTITUTION:A coordinates conversion part 1033 is provided to an inspection device 1032. The coordinates conversion part is connected to an external I/O part 1034. When the inspection device has a coordinates system with a coordinates number of Ci, the conversion method can be written as F(Ci, CN) for output and F(CN, Ci) for input. An operator performs data arrangement operation and I/O of data for the inspection device being based on all standard coordinates system. The CN may agree with either one of C1, C2, and C3. Even if it does not agree, the coordinates system which is adopted previously agrees with the CN. No coordinates conversion part is required for the inspection device. Thus, selection of either one of C1, C2, and C3 for the standard coordinates system which is used most frequently for the inspection device eliminates the need for labor for mounting the coordinates conversion part.

Abstract: PROBLEM TO BE SOLVED: To prevent a drain hole plug from coming in contact with a ball chain at the time of taking a bath by making the radius of curvature smaller for an area from a bathtub standing wall to a bottom drain hole position, compared with the radius of curvature for an area from a peripheral bathtub standing wall to a bottom, for forming a recessed groove on the bathtub standing wall, and providing a drain hole on the bottom of the recessed groove. SOLUTION: A bathtub 1 is formed out of FRP and integrally molded at a press molding process using upper and lower molds. In this case, the curved part of the bathtub 1 around a drain hole 2 is formed to have a cross sectional shape having, for example, a radius of 50mm for a standing direction. Also, a standing wall 7 around the drain hole 2 is set approximately at three degrees for a vertical line, while a curved part 3 around the drain hole 2 is formed to have a cross sectional shape having, for example, a radius of 3mm for a standing direction. Furthermore, a standing wall 7 is erected approximately at two degrees relative to a vertical line. As a result, an area in the vicinity of the drain hole 2 is recessed and the drain hole 2 comes to be formed as the recessed groove 5 of a bathtub bottom.  Thus, a bathing person, even when moving in the bathtub 1, does not come in contact with the drain hole 2. In particular, his/her contact with the ball chain 8 of a plug for the drain hole 2 can be prevented.
