Patent JP-H1094407-A (JP)
Title: Accessory and manufacture thereof
Inventor: NAKAMURA YUTAKA
IPC: A44C7/00
Filed: 1996-09-21
Abstract: PROBLEM TO BE SOLVED: To impart springiness, and dispense with positional adjustment of a pierced earring pin and a receiving part, by forming an accessory of a first metallic raw material wound by outward turning projecting stripes arranged on both side ends and a second metallic raw material wound by striding over the adjacent projecting stripes of the first metallic raw material by these projecting stripes by inward turning the projecting stripes. SOLUTION: When an accessory is manufactured, first of all, a metallic raw material A is wound round a core body 20. This metallic raw material A has projecting stripes 1 and 2 on its both side ends, but are wound round the core body 21 by outward turning these projecting stripes 1 and 2. Next, they are wound so as to stride over the adjacent projecting stripes 1 and 2 by inward turning projecting stripes 3 and 4 by a metallic raw material B having the projecting stripes 3 and 4 on both side edges. Next, the metallic raw materials A and B are plastically deformed by performing press working from the inside and outsed by rollers 101 and 102 , and the projecting stripes 1 and 2 and the projecting stripes 3 and 4 are engaged with each other, and springiness is imparted.  In the case of pierced earrings, they are plastically deformed in a ring shape, and are formed as a decorator main body S, and a pierced earring pin 5 and a receiving tool 6 are brazed to these both end parts.

Title: Control device for engine
Inventor: ISHIBASHI YUKIO
IPC: F02B37/12
Filed: 1988-10-26
Abstract: PURPOSE:To prevent the generation of torque-steering phenomenon with good responsiveness by reducing output of an engine a specified amount when the amount of change in engine torque hourly detected registers ascent above a specified value. CONSTITUTION:An engine A is loaded on a vehicle whose steering wheel is formed to be driven. In this instance, a means B detects engine torque based on the engine torque itself or any torque parameter indicating the engine torque. When the amount of change in engine torque hourly detected by the means B registers ascent above a specified value, a means C controls output of the engine A to be reduced a specified amount. As a result, the generation of torque- steering phenomenon is prevented with good responsiveness, and steerability is improved.

Title: Aerial floating device
Inventor: MIKI NOBUAKI
IPC: B64C27/20
Filed: 1987-10-27
Abstract: PURPOSE: To ensure the stability of yawing by transmitting engine power to a drive shaft and a rotor shaft through a bevel gear and rotating a rotor in the reverse direction to a propeller. CONSTITUTION: Power of an engine 1 is transmitted to a propeller 7 and a rotor 8 through a bevel gear of a double inversion mechanism 2 to generate buoyancy due to a stream of air flowing in a duct 9 and to lift a floating device in the air. At this time, the duct 9 receives yawing action due to the rotation of the propeller 7, but the rotor 8 rotates in the opposite direction for the propeller 7 so that inversion torque is generated due to the rotation of the rotor 8 to prevent yawing. Consequently, it is possible to simplify a structure of this device by adopting the bevel gear in the double inversion mechanism 2 and ensure the stability of yawing.

Title: Noise reduction circuit
Inventor: NAKADA MASAHIRO
IPC: H04N5/20
Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To reduce noise feeling at a low APL screen by detecting the average luminance level (APL) and the peak luminance (IRE) of a video signal, comparing them with reference voltage which is arbitrarily set and controlling the amplitude, sharpness and the color saturation degree of video output. SOLUTION: A first comparator 3 compares APL detection voltage with reference voltage V1 becoming an operation start point. A second comparator 4 compares IRE of the signal with reference voltage becoming the operation start point. Output voltages V3 and V4 from the first comparator 3 and the second comparator 4 are inputted to a control circuit 9 controlling the amplitude of video output through an AND circuit 7 and an amplifier circuit 8 controlled by V3. Thus, the luminance noise of video output can be reduced by suppressing contrast control voltage in the control circuit 9 in accordance with output voltage V5 from the comparator in the APL detection circuit 1.

Title: Operation of ball cleaning system for condenser
Inventor: AIHARA TAKESHI
IPC: F28G1/12
Filed: 1985-12-05
Abstract: PURPOSE:To increase the collecting rate of balls remaining in the neighborhood of sluice valves for use of cleaning up to 100%, by slightly opening the sluice valves for use of reverse cleaning provided between water chambers when ball catchers are still ready to collect balls after a work of cleaning balls have finished. CONSTITUTION:Some balls 23 are remaining without fluidizing during cleaning balls (32), while some of them flow out at the time of reverse cleaning (31), so that the remaining balls must be collected between cleaning of balls and reverse cleaning of them. In order to fluidize the remaining balls, sluice valves 17 and 18 for use of reverse cleaning are slightly opened (SO). Then a water flow, flowing from the inlet water-chambers to the outlet water-chambers through water-chamber connecting pipes 15 and 16, is produced by the pressure difference, which is more than 5 meters by water-guage pressure, between the inlet water-chambers 3 and 5 and the outlet water- chambers 4 and 6, and the remaining balls 23 in the neighborhood of sluice values are moved into the outlet water-chambers to be discharge to the downstream side. This process is to take place when cleaning of balls and collection (33) have been finished and ball catchers 21 and 22 are ready to collect balls. When the sluice valves for reverse cleaning are slightly opened, the sponge balls 23 remaining in the neighborhood of the valves are fluidized to be collected (34) by the catchers.

Filed: 1990-10-12
Abstract: PURPOSE:To draw a complicated pattern with high accuracy and in a short time by a method wherein a drawing operation is executed by using a slit having a pattern, in a region which can be expressed in common out of prescribed patterns, as a specific pattern. CONSTITUTION:A substrate is irradiated sequentially with an electron beam through a slit 1 which partitions an irradiation region; a prescribed pattern is drawn on the substrate. At this time, the drawing operation is executed by using the slit 1 having a pattern, in a region which can be expressed in common out of prescribed patterns, as a specific pattern. When the shape of the slit 1 at an aligner has the specific pattern, the pattern can be drawn with good accuracy by one exposure operation. The specific pattern at this time refers to a pattern having the region which can be expressed in common on a mask pattern designed by a specific technique and a pattern which is formed at the aligner as a slit pattern. Thereby, an error caused by the combination with conventional patterns is eliminated, and the number of exposure operations can be reduced. As a result, an exposure accuracy and a treatment ability are enhanced.

Thence, the leading one bit of a Huffman code data string (d) is sent to the least significant address AL of the memory 3, and three bits lover than that are inputted to the A1 of the selector 2. In such a case, the selector 2 selects the A1 when decoding in unit of four bits is performed, and the data of AQ when it is performed in unit of one bit by a select signal (e), and sends output three bits to the address AHL of the memory 3. A decode word (a), code length (b), or a pointer and a flag (c) are outputted from the memory 3. Such operation is repeated again in the case of pointer.
