Title: Image forming device
Inventor: WATANABE JUNJI
IPC: G03G15/20
Filed: 1988-01-18
Abstract: PURPOSE:To reduce the cost and to simplify the structure by enabling an image carrier and a fixing a device to be switched to >=2 speeds by switching clutch mechanism while a developing device is driven at a fixed speed, using a common driving source. CONSTITUTION:The image carrier 20, the developing device 24, and the fixing device 35 are driven with the common driving source 101, and at the same time the clutch mechanism which enables the switching of the driving speed to >=2 speeds in a driving system for the image carrier 20 and the developing device 24 is provided. Therefore while keeping the driving speed of the developing device 24 constant by the common driving source 101, the image carrier 20 and the fixing device 35 can be driven at a different speed by switching the clutch mechanism. Thus the cost can be reduced, and the movements of each device can be simply but surely synchronized.

Title: Process for separating solid from liquid
Inventor: SENDA TERUO
IPC: B01D24/38
Filed: 1987-01-19
Abstract: PURPOSE:To maintain the capacity for separating solid from liquid of a filter cloth at high level for a long time by feeding a liquid to be filtered intermittently in a stage of separation of solid from liquid using a filter cloth travelling type solid/ liquid separation apparatus. CONSTITUTION:A liquid to be filtered contg. a solid component and a liquid component is fed from a solid/liquid feeding tank 13 onto a filter cloth 1 running and circulating in the arrow direction be being drive by a driving roll 2, and the liquid component in the liquid feed is allowed to pass through the filter cloth 1 and collected in a vacuum sucking tank 11. On one hand, the component which has not passed through the filter cloth 1 is scraped off as cake with a scraper 12 to the outside of a dehydrator, then the liquid feed is fed intermittently from a solid/liquid feed pipe 23 to the solid/liquid feed tank 13 when the filter cloth 1 is washed by the washing water ejected from a filter cloth washing nozzle 21. As the result, the clogging of the filter cloth 1 is restored by washing the filter cloth 1 effectively during the suspension of supply of the liquid feed, so the capacity for separating solid from liquid of the filter cloth 1 is held for long time at a level higher than the predertermined level.

IPC: H04N1/21
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To drastically reduce waiting time for an original reading processing by giving priority to access by read image information over the access by information except the image information when the access is requested by the read image information while an image reader is recognized as being accessed by the information except the image information. SOLUTION: When the access is requested by the image information read by a mounted original reading means 11 while the image reader is recognized as being accessed by the information except the image information by a recognizing means 5, priority is given to the access by image information read by the mounted original reading means 11 over the access by the information except the image information. When copying processing inputted from the mounted original reading means 11 during print processing, priority is given to an input processing by the mounted original reading means 11 over the print processing and after that, the input processing by the mounted original reading means 11 is periodically (e.g. by every five seconds) performed. In other word, a mounted original is inputted without waiting for the print processing being precedingly executed for a long time.

Abstract: PURPOSE:To efficiently spray a number of kinds of chemicals, by selectively opening switching valves by operation of a selection switch to introduce pressurized air into air branches, causing the pressurized air to optionally suck chemicals in a tank, and spraying them through a blow-off port into a room of a car. CONSTITUTION:Chemicals blow-off ports 10c, 10d of a plurality of chemicals spray nozzle units N1-N4 provided on a spraying device are separately connected to chemicals tank 81-84 through chemicals communications lines 121-124. Air blow-off ports 10d, 11d of the units N1-N4 are independently connected to air branch lines 141-144, while an air main line 14 is connected to a pressure air supply source U and the lines 141-144, in which lines 141-144 switching valves 15a-15d are interposed respectively. By operating a selection switch 23 connected to those switching valves, the switching valves 15a-15d are selectively opened to optionally suck the chemicals in the chemicals tank 81-84 by means of pressurized air so as to spray the chemicals into a room of a car. As a result, it is possible to alternately spray a number of kinds of chemicals efficiently into a room of a car using a single device.

Title: Apd bias control system for optical reception circuit
Inventor: GESHI YASUO
IPC: H04B10/564
Filed: 1990-01-18
Abstract: PURPOSE:To make an output of an amplifier system stable independently of the presence of a transmission signal by switching two bias modes being variable and fixed bias modes provided in a 2-mode output bias control circuit in response to the presence of the transmission signal to control the APD bias. CONSTITUTION:When a signal is interrupted, since the bias control speed is slow, the detection output is rapidly small, a changeover switch 2 becomes the bias fixed mode and a 2-mode bias control circuit 3 keeps a bias applied to an PAD at that point of time. Then the APD bias is fixed to a value just before the signal interruption in the state of signal interruption. Moreover, even when the signal input is started, since the APD bias is in the state before input start, the output of the amplifier 5 is kept to almost a preceding signal level and outputted.

Title: Bar code reader
Inventor: IMAI YASUHITO
IPC: G06K7/00
Filed: 1995-01-24
Abstract: PURPOSE: To provide a bar code reader which can precisely be adjusted so that bar code readability becomes uniform in a read diameter and whose adjustment operation is easy. CONSTITUTION: A picture signal outputted from an image sensor in accordance with the reading of a bar code is amplified in an amplifier and is binarized in a binarization circuit. At an adjustment mode (120-Y), whenever a binarization signal is inverted during a period until scanning (reading) is terminated after the reading of the bar code is started, the signal levels of an amplification signal are detected and they are sequentially stored (140-200) after standby for prescribed time t0. After scanning is terminated, the amplitude A of the amplification signal is calculated based on the stored signal levels and the amplification factor of the amplifier is changed (230-270) when amplitude A is not within a prescribed adjustment range.  Then, the detection of the signal levels, the calculation of amplitude A and comparison with the adjustment range are repetitively executed until amplitude A comes into the adjustment range. Thus, stable binarization is executed because the amplification signal having prescribed amplitude A is inputted to the binarization circuit in terms of average.
