Patent JP-H01166461-A (JP)
Title: Support attaching structure and attaching thereof
Inventor: ASADA SHIGERU
IPC: H01K1/24
Filed: 1987-12-22
Abstract: PURPOSE:To make it possible to firmly wind a winding end of a support to a support attaching section by forming the support attaching sections of a non-circular cross section at specified intervals on a filament by pressing the filament to a flattened shape. CONSTITUTION:A pinch seal section 7 is formed on either end of an outer housing 4 within which is stretched a filament 3. A core wire and a filament 3 spirally wound about the core wire are together pressed to a flattened shape to form a support attaching section 5 of a non-circular cross section at specified intervals. Since the filament 3 at this support attaching section 5 is pressed flat, the filament 3 produces no spring-back even after the removal of the core wire by melting. This causes a support 1 to be firmly secured and the support 1 attached does not rotate about the filament 3 because of the non-circular cross section of the support attaching section 5.

Title: Image processor
Inventor: MAEDA MAMORU
IPC: G06T7/60
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent pseudo contour caused in a reproduction image in the case of conducting gradation processing by error spread processing. SOLUTION: An edge extract section 11 uses filters 1-3 to extract edge components in horizontal, vertical and oblique directions from image data and uses a maximum value of each absolute value as an edge quantity. A noise generating circuit 12 generates an M series random number having a required bit width by using a random number seed as an initial value and converts it by the edge quantity to generate noise. A pseudo contour is made unremarkable by increasing a random number in a smooth image area with a small edge and decreasing a random number in a rugged image area with a large edge quantity in the random number conversion. Data with the nose added to them are given to an error spread section 14, where an accumulated error of the image having been processed so far is added to the data to obtain output image data through quantization at a proper threshold level. The error caused for that time is distributed to surrounding picture elements with a weight by a weight table selected depending on a designation value by the user or the like.

Abstract: PURPOSE:To enhance oscillating efficiency by forming an opening area at the inlet side of a guide way divided by rectifying plates to the size reversely proportional to gas velocity. CONSTITUTION:Guide ways divided by straightens 22a and 22b inside a gas guide way 23 are referred to 23a to 23c starting from the outer side. If opening areas of respective inlet portions are S1 to S3 and respective mean gas velocities are V1 to V3, then the gas discharge in respective guide ways 23a to 23c is V1S1, V2S2 and V3S3 respectively. On the other hand, if the outlet of guide way, that is, the outlet of each guide way of the inlet of discharge region, has the same area S, then the gas velocity at the outlet can be respectively expressed by (V1S1)/S, (V2S2)/S and (V3S3)/S. Since, V1S1=V2S2=V3S3 must be satisfied, the velocities V1 to V3 are measured in advance, and the areas S1 to S3 are determined so that the above equation can be fulfilled. By doing this, the velocity at each outlet portion is made uniform and a high oscillating efficiency can be obtained.

Abstract: PURPOSE:To inhibit switching shock by switching between a valve timing for high speed and a valve timing for low speed based on the result of comparison between a first rotational speed and the rotational speed of an engine, and by switching and controlling an EGR valve according to the result of comparison between a second rotational speed and the rotational speed of the engine. CONSTITUTION:An EGR device 24 is provided, by which an exhaust route 7 of an engine 1 is connected to an intake route 6 by an EGR pipe 25 provided with an EGR valve 26, while a switching means for switching valve timing of intake and exhaust valves 12, 13 between two modes of high speed and low speed, is provided on a cylinder head 11. When the rotational speed of an engine is not more than a first rotational speed, the valve timing is switched into a low speed mode, and when it is not less than the first rotational speed, the valve timing is switched into a high speed mode, by an ECU 57. When the rotational speed of the engine is not more than a second rotational speed or less than the first rotational speed, the EGR valve 26 is opened to execute EGR, and the EGR valve 26 of no less than the second rotational speed is closed. Torque shock generated when the EGR valve is opened/closed is thus suppressed at the time of switching valve timing.
