Title: Semiconductor device and fabrication thereof
Inventor: AKAI SUMIO
IPC: H01L29/78
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device in which punch-through resistance is enhanced by suppressing short-channel effect and a fabrication method thereof. SOLUTION: A well region is formed by implanting impurity ions through a silicon oxide film formed on one major surface of a single-crystal silicon substrate 1 and then performing annealing. P-type impurity ions are then implanted at a part for forming an LOCOS film 2 using a resist mask. Subsequently, a silicon nitride film is formed on the silicon oxide film, and an LOCOS film 2 is formed using the silicon nitride film having an opening as a mask before removing the resist film, the silicon nitride film and the silicon oxide film. Thereafter, a tapered trench 4 is made in a part for forming an insulating gate 6 through photolithography and etching before forming the insulating gate 6 of polysilicon layer in the trench 4 through the silicon oxide film 5.  Finally, a drain region 8 and a source region 9 having an impurity concentration gradient in the lateral direction are formed by conducting ion implantation and annealing, using the insulating gate 6 as a mask.

Title: Braking pressure holding controller for vehicle
Inventor: ITO KAZUNORI
IPC: B60T11/28
Filed: 1986-09-08
Abstract: PURPOSE:To dispense with side brake operation and simultaneously make operation during travel performable as well as to eliminate any hindrance against running, by installing a controller which forcily opens a valve body of an on-off valve at a time when a car speed is more than the specified value. CONSTITUTION:In this control unit, there are provided with an on-off valve 11 being installed in a pipeline 6, a first valve forced opening device opening this valve body, a second forced opening device 21, a car speed detecting sensor 23, and a controller 22 forcedly opening the valve body of the on-off valve 11 by the second forced opening device 21 at a time when the detected car speed is more than the specified value. With suck like constitution, since the car speed is more than the specified value during travel, the on-off valve 11 is forcedly opened, making brake operation performable. When the car speed becomes less than the specified value, forced opening is stopped, and the brake operation is carried out through the on-off valve 11. Therefore, the on-off valve 11 functions, holding braking pressure, and side brake operation is made unnecessary, therefore the braking pressure is released by the first valve forced opening device, with operation of a clutch and accelerator pedals 20 and 24, thus running is made possible.

Title: Scroll compressor
Inventor: TANIGAKI RYUHEI
IPC: F16K17/02
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a scroll compressor by providing the end plate of a fixed scroll with a hole to make a high and a low pressure side communicate mutually and moreover a high pressure relief valve in the above hole. SOLUTION: A high pressure relief valve 60 is composed of a ball 62 to abut on a seating face 61 formed in a hole 66, a spring 63 to press energize the ball 62 toward the seating face 61 under fixed setting force, and a spring support 64 to support the one end of the spring 63. During the operation of a scroll compressor, a difference between pressure on a high pressure side 46 and that on a low pressure side 47 attains a fixed value, the ball 62 of the high pressure relief valve 60 separates from the seating face 61 against the bursting force of the spring 63, and the gas on the high pressure side 46 passes through the hole 66 and the high pressure relief valve 60 and flows to the low pressure side 47. The pressure on the high pressure side does not therefore rise above a prescribed pressure for preventing the damage of a scroll compressor.

IPC: G01S13/04
Filed: 1994-09-05
Abstract: PURPOSE: To automatically remove false image or a target when the false image of the target is produced in images on a display. CONSTITUTION: The dispersion of the center of gravity of a target and the size in the circumferential direction of the target are obtained from a video signal HVD. When these values are larger than a reference dispersion which is a constant reference value and a reference size, an image of the target on a screen 1 of a monitor 31 is determined as a false image. By automatically raising a correction threshold level signal ΔST, the value of a threshold level signal REF of a comparator 24 for obtaining the video signal HVD is automatically raised to remove the signal relating to a false image of the video signals VD. Stable capture and tracking of the target are made possible.

Title: Method for coating drum
Inventor: GOTO SUSUMU
IPC: B05C3/04
Filed: 1990-08-10
Abstract: PURPOSE:To remove the unevenness of an application solution applied to the outer periphery of a drum by dipping the drum into the application solution in a tank while agitating the solution and receding the drum from the solution in the suspending state of its agitation. CONSTITUTION:In the case of dipping the drum 10 into the application solution 20, the application solution 20 is agitated and a high concentration application solution part stayed in the solution 20 is agitated and resolved in the solution 20. Since the solution 20 into which the drum 10 is dipped is allowed to flow upwards and overflowed, the high concentration application solution part resolved in the solution 20 in the dipped state of the drum 10 into the solution 20 is overflowed to the outside of the tank 30. Then, the drum 10 is receded from the solution 20. Thus, the generation of unevenness of the solution applied to the outer periphery of the drum 10 can be prevented.

Filed: 1988-08-26
Abstract: PURPOSE:To rapidly execute the arithmetic processing of a large quantity of picture element data by writing data having a logical operation result obtained by a logical computing element as a constitutional bit in a required line of a memory cell array. CONSTITUTION:A memory 11 arraying memory cells to be storage elements in (m) lines and (n) rows is allowed to read/write data in each (n) bits of a line and a computing element 12 executes the logical operation of a function f(MA, a0...a1). The computing element 12 executes operation between data MA for a line read out of the memory 11 and other arguments a0...a1 and writes the operated result in an optional line of the memory 11. Since the memory 11, the computing element 12, etc., are constituted in the same integrated circuit, the arithmetic processing such as picture element can be executed only by its inside. Consequently, the arithmetic processing of a large quantity of picture element data can be rapidly executed.

Filed: 1987-08-26
Abstract: PURPOSE:To accurately measure a target position by measuring an image flow quantity by using the speed of a moving body and reproducing an image having no image flow by using the image flow quantity. CONSTITUTION:An A/D converter 3 digitizes a video signal outputted by an image pickup device 1. A speed indicator 1 detects the speed of a moving body where the image pickup device 1 is mounted and an image flow arithmetic unit 16 receives its output and calculates the image flow quantity. A fast Fourier transformer (FFT) 18 receives data outputted by the image flow quantity arithmetic unit 16 to find its Fourier transformation value. Further, a reverse FFT 22 finds the reverse Fourier transformation value which is the reciprocal of the Fourier transformation value through a reciprocal arithmetic circuit 20. A convolutional integration circuit 24 performs convolutional integration between the digital video signal 4 and reverse Fourier transformation data 23 and outputs playback image data 25 equal to an original image having no image flow. Consequently, an image inputted to an image tracking device 5 is an image having no flow and an accurate error signal 6 can be outputted.
