Title: Solid-state image pickup device
Inventor: HIGASHITSUTSUMI YOSHIHITO
IPC: H04N5/353
Filed: 1988-06-17
Abstract: PURPOSE:To smoothly change the level of a picture signal by always expanding or shortening the photoelectric conversion period of a solid-state image pickup element in a certain proportion to control the exposure. CONSTITUTION:A timing BT generating circuit T' is operated by the output of a comparing circuit C, and the output of an up/down counter 20 is decoded to binary data expanded or Shortened in a certain proportion by a decoder 21. Meanwhile, a step counter 22 is reset by a vertical scanning line signal VD and is counted up in the photoelectric conversion period by a clock signal CK having a cycle of 16 pulses per a vertical scanning line period V; and when the output coincides with binary data of the decoder output during this counting-up, an AND gate 24 outputs a discharge driving timing BT to a driving circuit D. Consequently, the photoelectric conversion period is shortened or expanded in the certain proportion each time when the up/down counter 20 is counted up. Thus, the level of the picture signal obtained from a solid-state image pickup element S is smoothly changed.

IPC: G01J5/34
Filed: 1987-06-19
Abstract: PURPOSE:To suppress a drift and to prevent sensitivity from lowering by setting the directions of peripheries of electrodes which are isolated from the outer peripheral edge of an element only in two directions crossing each other at right angles on the top and reverse surface. CONSTITUTION:Which of the electrodes 2 and 2' of the infrared detecting element is a main electrode is not specified, two opposite sides of both are isolated from the outer peripheral edge of a pyroelectric element 1, and the directions of the two sides cross each other at right angles between the electrodes 2 and 2'. Consequently, the entire outer periphery of a main electrode need not be at an equal distance from the outer peripheral edge of the pyroelectric element unlike before, and only two sides to be isolated need to be positioned, thereby reducing the trouble of electrode positioning to half. Consequently, a surface current is prevented from leaking owing to the abnormal approach between the electrodes due to short circuit of the out patterns of both electrodes and a position shift between both electrodes.

Abstract: PURPOSE:To obtain a stable black-and-white converted image signal even if the speed of a servo-motor varies by detecting the moving speed of an image sensor and varying the amplification factor of an amplifier or the reference comparative voltage of a comparator according to the detected moving speed. CONSTITUTION:A speed detecting circuit 33 differentiates the position signal of the position detecting circuit 29 for the servo-motor 26 to obtain a speed signal. This signal is set in a DA converter 34, whose output is compared with the reference black-and-white comparative voltage of the comparator 32, thereby converting an analog image signal to a binary black-and-white digital signal. When, the comparative reference voltage is converted in inverse proportion to the variation of motor moving speed. Consequently, the binary black-and- white image signal is obtained stably even when the output level of the image signal varies.

Filed: 1991-06-24
Abstract: PURPOSE:To easily obtain the stopping time of itself without issuing the request for acquiring the present time with a task by assigning respective kinds of resources (CPU time, main memory, etc.,) of a system with the task as a unit. CONSTITUTION:While a task is in a stopping condition, when the stopping condition is released by other task, a multi-task monitor subtracts the time when the task starts the stopping condition, from the present time (step 301). Thus, the stopping time of the task is obtained. The time value is stored into a memory area pointed out by a WaitTime designated by the task (step 302). Here, when a Task Wait service is the service to inform of the remaining time up to the limit time, the stopping time of the task obtained from a LimitTime is subtracted, and the value is stored in the memory area pointed out by the WaitTime. Thus, the stopping time of the task itself can be obtained as the turn-back value of the service from the multi-monitor.

Abstract: PROBLEM TO BE SOLVED: To obtain a high quality cutting plane by irradiating the approximate jetting position of a water jet head with a laser head diagonally from the front and thereby increasing the cutting capacity and speed. SOLUTION: A laser beam is emitted through an optical fiber 7 by a laser generator 4 and converged on a cutting position with a lens 2a in the laser head 2 to melt the position. The laser beam to be used is nonabsorbent in water, for example, a YAG laser beam.

The water jet 3 is disposed vertically to the object 1 in a manner that high pressure water is jetted to the irradiation part (fusion zone) of the laser beam. The fused material melted by the laser beam is blown off by the high pressure water in its jetting direction. The material can be blown away most efficiently by jetting the high pressure water vertically from a nozzle 3a at the tip end.

Abstract: PURPOSE:To prevent a low-temperature gas from flowing out of a heat insulating vessel and atmospheric moisture from entering the vessel when a current lead is loaded into or unloaded from the vessel, by providing a partition wall between the upper and lowr spaces in the vessel, and further providing a valve mechanism which opens and closes a current lead receiving through-hole when the current lead is fitted into and removed from the through-hole, respectively. CONSTITUTION:A partition wall 9 having a through-hole 9b capable of receiving or receiving a current lead 1 is provided in the center inside a heat insulating vessel. A valve mechanism 20 is disposed on the lower side of the partition wall 9. When the lead 1 is removed, the valve mechanism 20 acts in such a manner that a connecting blobk 7 is pressed by the force from a compression spring 12 which acts on a base 18 as a support which is suspended from the partition wall 9, and the block 17 is thereby pressed against the partition wall 9 to close the through-hole 9b while hermetically sealing it by a packing 14. Thus, there is no fear of He gas H1 in the lower space 16 leaking out to the upper space. When the lead 1 is fitted into the through-hole 9b, the block 17 is presses downward by the distal end 1c of the lead 1 pushed into the through-hole 9b, and the spring 12 is thereby compressed, thus bringing the mechanism 20 into an open condition. In consequence, the gas H1 is led in the direction of the arrows to cool the lead 1.
