Title: Image recorder
Inventor: TAMAOKI SHUNPEI
IPC: B41J2/205
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To record images with high picture quality by carrying out the inter- pixel thinning processing where only the remarked pixel that is smaller than the prescribed changing point total number threshold is stored as a true edge pixel. SOLUTION: In regard to a remarked pixel X that is decided as an edge pixel, the peripheral pixel total number Sb is calculated. Then the changing point total number Sc is calculated in the main scanning direction among the peripheral pixels. The changing point total number threshold Sth corresponding to a black pixel number range is read out based on a black pixel number range- threshold Sth table. When the number Sc is larger than the threshold Sth, the pixel X is decided as a false edge pixel and simply thinned like the remarked pixel that is not decided as an edge pixel against the remarked pixel. When the number Sc is smaller than the threshold Sth, the pixel X is decided as a true edge pixel and undergoes the edge storage thinning processing against the remarked pixel.

IPC: G06F3/033
Filed: 1981-09-30
Abstract: PURPOSE:To perform simultaneous input to plural different positions in an input surface by allowing plural resistance sheets to face mutually in matrix structure, and partitioning the input surface into plural independent areas. CONSTITUTION:Resistance sheets 6 and 7 form two-divided areas of an upper resistance sheet 1 in a direction Y, and the remaining two resistance sheets 8 and 9 form two-divided areas of a lower resistance sheet 2 in a direction X. Then, the 1st input surface A is formed on the opposed surfaces of the upper and lower resistance sheets 6 and 8 facing at right angles, and the 2nd input surface B is formed of the sheets 6 and 9; and the 3rd input surface C is formed of the sheets 7 and 8, and the 4th input surface D is formed of the sheets 7 and 9. Thus, the respective resistance sheets 6, 7, 8, and 9 are arranged while insulated from one another, so simultaneous input to the respective input surfaces A-D is possible.

Title: Hydraulic control unit for four-wheel drive transfer
Inventor: HAYAKAWA YOUICHI
IPC: B60K17/344
Filed: 1981-09-30
Abstract: PURPOSE:To securely prevent the speed from changing into a speed reduced state of four-wheel drive when running at high speed by setting a transfer into a directly connected state of two-wheel drive or a directly connected state of four-wheel drive when either P or N range is determined. CONSTITUTION:A transfer 10 for four-wheel drive is connected to the rear of an automatic transmission 1 and selects a directly connected state of two-wheel drive or four-wheel drive or a speed reduced state of four-wheel drive with frictional engagement elements 7, 5 and 8 each for direct connection, speed reduction and four-wheel drive. When the manual shift of the automatic transmission 1 is set to either N or P range and the governer pressure is reduced to zero, the transfer 10 is set to either a directly connected state of two-wheel drive or that of four-wheel drive.

Title: Method and apparatus for collecting dust
Inventor: ISOZAKI HARUYOSHI
IPC: B01D46/04
Filed: 1985-07-16
Abstract: PURPOSE:To increase the regeneration efficiency of a bag due to backwash by sucking the clean air incorporated in the bag through an exhaust duct, exhausting it and stopping the air flow of the inside of the exhaust duct in a period of the dust scraping due to the injection of pulsed air. CONSTITUTION:In a period of dust collection of dust-laden air, firstly a suction fan 30 is operated to introduce the dust-laden gas through an introduction duct 25 and it is diffused with a baffle plate 26 and passed through the bags 24 to filter and collect dust. In a period of the regeneration of the bags pulsed air is injected from an aperture part of the top end to the insides of each bag 24 through the nozzles 35a. In this case, the air flow incorporated in each outlet duct 27a of an exhaust duct 27 is stopped at a time during the period of injection of the above-mentioned pulsed air. Thereby the suction action due to the fan 30 is not acted in the insides of each bag 24 and in this state, the high- pressure pulsed air injected to the insides of each bag 24 from apertures of the top end is not decreased in pressure and both the backwash and the scraping of the collected dust can be performed.

Title: Wave corresponding outflow oil recovering device
Inventor: UEDA KOICHI
IPC: B63B35/32
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To recover outflow oil of high viscosity in waves, by guiding the outflow oil by a guide net belt driven by a shaft vertical to the water surface. SOLUTION: In case of recovering outflow oil 12 of high viscosity and gelling oil, a recovering net belt 1 is turned in the moving direction 10 by a net belt drive pulley 11, recovered high viscosity oil is scraped by a wiper 13 and recovered in a tank 5. In case of low viscosity oil, oil passing through the recovering net belt 1 is recovered by a suction pipe 6. Since this recovering net belt 1 is a net, water flows through a mesh, a reverse flow and a counteracting wave are decreased in a recovering part by the net belt 1. Consequently, resistance relating to an oil layer and a flow of water is decreased, an outflow oil layer is easily guided to the recovering part. Since the net belt 1 can be inserted deeply in the water, high viscosity oil can be recovered even in waves.  In case of the low viscosity oil, since waves to the rearward is damped by the recovering net belt 1, an oil layer between the recovering net belt 1 and a suction recovering part is stabilized, and the oil is easily recovered.

Title: Discharge-type excimer laser device
Inventor: KAWAMURA SHINICHIRO
IPC: H01S3/0977
Filed: 1988-06-27
Abstract: PURPOSE:To make it possible to start to pass a discharge holding current constantly at a fixed timing immediately after a main discharge starting current begins to flow and to prevent rapid triggering or slow triggering by providing a current sensor which detects a discharge starting current inside a discharge starting circuit. CONSTITUTION:A current sensor 8 which detects a current flowing inside a closed loop circuit consisting of a capacitor C2, preliminary ionization electrode 3 and main discharge electrodes 4, 5 detects a discharge starting current which flows when discharge of laser gas between the main discharge electrodes 4, 5 begins and sends the signal to a switch 6 as a trigger pulse signal. According to this constitution, if the switch 6 closes, a charge stored in a capacitor C3 is consumed to keep the discharge already made between the main discharge electrodes 4, 5 to attain to laser oscillation. If the time needed to actually start main discharge varies greatly, the discharge holding current flow can be always made most timely. Misfire can be eliminated and a life of a main discharge electrode and laser gas can be improved in this way.
