Inventor: YAMASHITA KOSUKE
IPC: F16J15/46
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide the method and device for sealing a sliding part or a movable part, having a comparatively big size and a high using temperature atmosphere, by a method wherein gas is filled into a space between sealing members and is supplied thereinto while regulating the supplying amount so that the pressure of the gas is maintained so as to be higher than that of the outside of the sealing members. SOLUTION: A seal member 13, consisting of a plate seal made of a stainless steel, and seal members 14, 15, consisting of a drum seal made of a heat resistant cloth with a set-in steel sheet, are arranged in triple. A gas supplying unit 17 is provided in a space 16 between the innermost side seal member 13 and the second seal member 14. In this case, the atmospheric pressure in the space 16 is measured with a micromanometer 21. An external pressure is an atmospheric pressure and is constant therefore, the actual measurement is not required. Only the atmospheric pressure in the space 16 is measured actually by the micro pressure gauge 21 and the supplying amount of gas into the space 16 is regulated by a valve 22 so that the internal pressure of a rotary kiln is maintained at a value higher than the set value or the atmospheric pressure.

Title: Chattering elimination circuit
IPC: H03K5/1254
Filed: 1992-03-13
Abstract: PURPOSE:To provide the chattering elimination circuit adopting digital logic components for its circuit components, integrated easily in an LSI whose characteristic is easily revised. CONSTITUTION:A chattering elimination circuit employs three D flip-flop circuits D1-D3, a selector SC, an exclusive EOR, a counter circuit CT, a comparator DCP, and a digital filter comprising some gate elements. The counter circuit CT increments counts as '1', '2', '3', '4' in response to the leading from a clock signal CLK without being reset during 5 sampling periods of a key input signal INPUT.

Title: Automatic sheet feeding apparatus
Inventor: ASAKA NOBORU
IPC: G03G15/00
Filed: 1988-03-08
Abstract: PURPOSE:To enable prevention of double feed of sheets and the occurrence of sheet jam and impossibility to feed sheets, by a method wherein the rotation means of a feed roller is mounted on a feed roller shaft and a fed tray or a cassette situated in a feed part. CONSTITUTION:A feed tray 1 containing sheets 2 therein is inserted, as shown by an arrow mark A, to the feed part of a duplicator or a printer. When the insertion is progressed to a final stage, the sheet 2 at an upper part in the tray 1 makes contact with a feed roller 3 in a feed part, and is about to be displaced in a position in the direction of a sheet guide part 5 togetherwith the sheet 2 situated therebelow. In this case, on the feed part side, a toothed roller 10 mounted on a shaft 9 is brought into contact with a rubber plate 11 mounted to the tray 1 to rotate the toothed roller, and the roller 3 is rotated in the direction of an arrow mark C. Rotation of the roller 3 prevents displacement in a position of the sheet 2 at an upper part in the tray 1. Since, even when the sheet 2 is brought into contact with the roller 3, a containing position is not moved until the tray 1 is completely set in the feed part, the roller 3 is prevented from being nipped between the roller 3 and a pad 6.

Abstract: PURPOSE:To perform fast processing by using arithmetic option OP efficiently by providing each CPU, sharing arithmetic OP, with a means of selecting either its arithmetic or arithmetic OP at the finishing of the operation of arithmetic OP. CONSTITUTION:High-speed arithmetic OP13 is shared between CPUs 111 and 112 and FF21 is set with request signal from CPU to send signal BSY, showing that operation is in process, to each CPU. If CPU112 detects signal BSY when to send a request for processing to OP13, signal ST is not sent out and the same processing as that requested to OP13 is performed by microprogram processing mechanism 22 simultaneously flag 23 is set. Although flag 23 is reset a prescribed time later, OP end signal END is outputted via gate 25 if signal BSY is held at ''0'' during its set period; and mechanism 22 stops its processing in response to the signal and sends signal ST to OP13 to request the processing to OP. If signal BSY is held at ''0'' after flag 23 is reset, mechanism 22 continues its arithmetic processing.

Filed: 1988-03-10
Abstract: PURPOSE:To eliminate the irregularity of deterioration due to the difference of positions of recording elements by recording by a density gradation method by using a dot developed pattern formed in advance thereby to average the using frequency of the elements. CONSTITUTION:Density data received from a host side through an interface 3 is developed to dot information capable of being developed to an image buffer 4 in a LUT (lookup table). In this case, the value of density data supplied from a host side corresponds to a drawing No.0 in case of 0-15, to No.1 in case of 16-31, to No.2 in case of 32-47, to No.15 in case of 240-255. Since the content of the LUT 2 is so formed that the driving ratios of nozzles become equal when the presenting probabilities of the density values are equal, the difference of deterioration degree due to the difference of the positions of the nozzles can be reduced when a recording head is used for a long period of time. the head reads the dot image developed in the buffer 4 by a MPU 1, transfers it, for example, to the electrothermal converter of the nozzle, and records it.
