Title: Automatic straight running return device for hydraulic power operated auxiliary steering device
Inventor: KITAMURA TOMIMASA
IPC: B62D5/22
Filed: 1985-10-19
Abstract: PURPOSE:To strengthen the stability of steering wheel return by providing a straight return control valve working on a detecting means for the rotary angle position of the wheel and supplying hydraulic pressure from said valve selectively to a right or left side return hooking means. CONSTITUTION:When a torsion bar 3 connecting an input axis 1 to an output axis 2 is free from any twist, a return valve 50 is neutral and oil passages 27 and 28 are exposed to equal pressure. If a steering wheel is turned to a right side steering position exceeding a straight running angle range, the return valve 50 is actuated by a potentiometer 45 and hydraulic pressure is supplied to a left side return oil passage 43, Then, the oil passage 28 is exposed to higher pressure than the passage 27, thereby returning the steering wheel to a straight running position. On the contrary, when the steering wheel is turned to a left side steering position, the oil passage 27 undergoes higher pressure than the passage 28, thereby returning the steering wheel to a straight running position, as well. As a result, high stability is ensured for the return of the steering wheel.

Title: Coffee liquid extractor
Inventor: KAWAI NOBUYOSHI
IPC: A47J31/043
Filed: 1988-09-19
Abstract: PURPOSE:To provide a coffee liquid extractor capable of extracting coffee liquid with water by providing a relief valve for closing automatically an air path affording communication between the interior of a server and atmospheric air when water in the server is boiled, while providing an adjusting means for adjusting the path area of the air path. CONSTITUTION:A funnel 12 is mounted on a server 7 to seal hermetically an opening on the upper surface of the server 7, and coffee powder and water are put into the funnel 12. Then, a spring 35 under the compressed condition opens an air path 33, and coffee liquid extracted by water falls through a pipe 13 into the server 7. The speed of coffee liquid extracted into the server 7 is adjusted by an adjusting screw 31. When current is supplied to a heater 2 in the syphon type coffee liquid extraction, the spring 35 under the compressed condition opens the air path 33 so that air in the server 7 is exhausted through the path 33 to the outside. When water in the server 7 is boiled, the spring 35 is extended so that a valve portion 25 abuts against a receiving portion 29 of a valve seat 28 to close the path 33.

Title: Solid-state image pickup device
Inventor: AOKI MASAKAZU
IPC: H04N5/335
Filed: 1983-12-14
Abstract: PURPOSE:To inhibit the phenomenon of blooming and the photosensitization of a signal line by a method wherein a drain region for a photo gate is formed more shallowly than a source region and over the upper part of the surface of a conductor substrate, and the area of a region thereon is made wider than the area wherein the drain region contacts with the semiconductor substrate. CONSTITUTION:A photodiode 102 is an N<+> layer formed by phosphorus diffusion, and the drain 110 an N<+> layer using As. The phosphorus diffusion has a high short wavelength sensitivity which is important for a sensor, and is suitable for the photodiode. Since the n<+> layer using As is apt to form a shallow junction and can obtain low layer resistance even by a shallow junction, it is suitable for a read-out drain and the source and drain of an MOS transistor of a peripheral circuit. This drain 110 is formed in the upper part of the P type substrate 101. Therefore, the probability of the inflow of carriers due to lateral bi-polar effect into the drain is very low. Besides, the carriers generated in the P type become long in the distance of reaching the drain. Accordingly, the probability of the inflow into the drain increases. Thereby, the potential barrier corresponding to a dummy signal carrier is formed and then prevented in the same manner as in the case of the dummy signal carrier 109.

Abstract: PURPOSE:To obtain the field data including the reliability, etc. by adding a memory circuit to store the total switching frequencies of plural attenuators and then informing an operator of these frequencies before the end of the attenuator's lifetime. CONSTITUTION:A memory circuit 33 stores the total switching frequencies of attenuators 2-9 of program attenuators 1a and 1b to the memories 2-a-9-a respectively and increases its memory contents for each switching of each attenuator. When a display mode is selected via a key input circuit 13, the total switching frequency of each attenuator is read out of memories 2-a-9-a of a memory 13 respectively and then displayed. Based on this display, an operator replaces the attenuator that possibly has its lefttime expired. At the same time, the field data is obtained by the total switching frequency of an attenuator made known in a fault mode.

Title: Apparatus for automatically sealing envelope
Inventor: YAMADA MASAHIKO
IPC: B43M5/04
Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To enhance the cutting efficiency of a tape in automatic sealing. SOLUTION: A cutter 59 for cutting a tape is constituted by superposing a main cutter 591 having an edge part linearly formed thereto and a sub-cutter 592 of which the edge part is formed into a saw-tooth shape one upon another. Since the edge part of the sub-cutter 592 slightly retreats from the edge part of the main cutter 591 and the respective edge parts are attached to a cutter holder 58 mutually parallelly when the cutter 59 cuts in the tape, a base material is cut at first by the main cutter 591 and the self-adhesive surface is subsequently cut by the saw-tooth edge of the sub-cutter 592 to cut the tape. Therefore, the self-adhesive layer of the tape can be certainly cut and the interruption of work can be eliminated.

Title: Vertical edge detecting circuit
Inventor: IIDA YASUHISA
IPC: G06T7/60
Filed: 1987-09-21
Abstract: PURPOSE:To detect a vertical edge at real time by using a clock signal corresponding to the horizontal resolution of an image and using a signal on one scanning line of a binary image as a latch signal to find out the vertical edge of the image. CONSTITUTION:When a horizontally synchronizing signal is applied, the image of a 1st scanning line starts to be outputted from a TV camera 1, a clock signal simultaneously starts to be outputted from a clock signal generator 8, a 1st counter 17 counts up the clock, and '1' is added to the output of a 2nd counter. When the image signal is turned from 'dark' to 'bright' under said status and the output of a comparator is turned to 'H', 1st and 2nd latches 10, 20 are latched and the outputs of corresponding counters are temporarily stored. As the result, the output of the 1st latch 10 indicates the position (i) of the vertical edge and the output of the 2nd latch 20 indicates the number (j) of scanning lines, i.e. '1', at the time of detecting the edge. During the period, the 1st counter 17 continues to count up clock signals. Even when a vertical edge from 'bright' to 'dark' appears, the position can be similarly detected.

IPC: H01L21/205
Filed: 1988-09-20
Abstract: PURPOSE:To improve controllability of film thickness at the time of formation of an Si film by supplying gas molecules in which specific numbers of halogen atoms and hydrogen atoms are bonded to Si atoms on to a semiconductor substrate, removing the hydrogen atom, applying the Si atoms, and then removing the halogen atoms. CONSTITUTION:Gas having a structure of SiX2Y2 in which two difficultly dissociated groups or atoms X and two easily dissociated groups or atoms Y with respect to Si are bonded is introduced to the surface of a semiconductor substrate 1 made of Ge, Si, etc., As the former halogen atoms are effective, and as the latter hydrogen is effective. The H is removed by a surface reaction, and the Si atoms adheres to the surface 3 in a state that the Si atom has the halogen X group. Since the SiX2H2 is not decomposed and not adsorbed on the halogen group of the surface, the adherence of the Si is stopped at one atom layer. Then, the substrate surface is heated while introducing the hydrogen gas, the halogen X on the surface is removed to obtain an Si surface. This is repeated to deposit Si one by one atomic layer. Accordingly, a desired film thickness can be obtained in the order of one atomic layer as the thickness of the Si film.
