Filed: 1991-05-16
Abstract: PURPOSE:To improve the transmission efficiency of data by diffusing and transmitting the band of the transmitting data for the bus formed by one physical medium, reversely diffusing the band of the receiving data and removing the original data. CONSTITUTION:In a diffusing circuit 100, a generator 60 inputs the signal from a setting part 65 and the clock from a generator 50 and prepares a self- correlation code.

Title: Multi-cylinder internal combustion engine
Inventor: KUMAGAI SEIICHIROU
IPC: F02B75/18
Filed: 1979-08-31
Abstract: PURPOSE: To reduce NO x , CO and HC by alternately causing the combustion in excessively rich air-fuel mixture cylinders and that of excessively lean air-fuel mixtures and permitting the resultant exhaust gases to be alternately led to a thermal reactor for mixing therein while also setting the overall air-fuel ratio to 15 to 17.  
     CONSTITUTION: Air from an air cleaner 1 is led to carburetors 2 and 2' for forming an excessively rich air-fuel mixture and an excessively lean air-fuel mixure. These air-fuel mixtures are withdrawn through respective intake manifolds 5 and 5' into respective combustion chambers 11 and 11', followed by the well-known operation of intake, compression, ignition and power strokes to produce exhaust gas. The exhaust gas enters through an exhaust port 12 into a thermal reactor 13. At this time, the exhaust gases from the excessively rich and excessively lean air-fuel mixture cylinders cause formation of spiral vortexes from each other and are sufficiently mixed together, whereby CO and HC in the exhaust gas are completely combusted with the residual oxygen in the exhaust gas. In addition, the generation of NO x  is reduced since it corresponds to one for the total cylinder volume of both the cylinders.

Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device which has both copy function and facsimile function which further reduce processing time by making reading of an original one time. SOLUTION: Variable power processing to image data and image processing, such as reflection (gamma correction) of density set values, are performed after the image data is divided into a write part 15 and a fax transmission processing part 17. Therefore, a copy output image and a fax transmission image can respectively be subjected separately to processing. Then, the size and density of an image can be set separately for copying and faxing. Also, because image data is respectively read and subjected to processing when copy is performed and when fax is performed, both the processing can simultaneously and be performed simultaneously and quickly.

Title: Wind-collecting device for wind mill
Inventor: SAKAI TOKIHIRO
IPC: F03D3/04
Filed: 1981-07-16
Abstract: PURPOSE:To improve the effect of wind-collecting by providing a wind mill frame in which a draft hole is bored containing a wind mill main shaft and wind mill blades coaxially inside and wind-collecting plates with triangular sections. CONSTITUTION:When wind blows against a side plate A of a wind-collecting plate 6' at the angle of about 30 degrees, the wind flows smoothly along a side plate B of the wind collecting palte 6'. Meanwhile, the wind can be partly blown against a wind mill blade 3 by a wind-collecting plate 7' for giving rotational power to the wind mill blades 3.

Since this side plate B is not perpendicular to the direction of the wind, the loss of resistance can be reduced in the case of drift. Besides, a wind-collecting plate 5' can also collect the wind by its side plate C.

Title: Picture reader
Inventor: TOMINAGA HIDEKAZU
IPC: H04N1/191
Filed: 1983-06-23
Abstract: PURPOSE:To easily improve and enlarge the resolution of a picture reader without using any line reading sensor of high resolution, by making the angle formed by the direction of picture element lines and the auxiliary scanning direction larger than 90 deg.. CONSTITUTION:When the length of a picture element line is represented by L2, an extent which can be read at once in a direction perpendicular to the auxiliary scanning direction becomes L2 costheta and is narrowed by costheta times as compared with a case where the picture element line is arranged perpendicularly to the auxiliary scanning direction. Therefore, reading is performed to a narrow extent with the same number of dots and, as a result, resolution in the main scanning direction is improved by 1/costheta times. Since the reading extent in the main scanning direction is narrowed by costheta times when a line reading sensor is set obliquely, the quantity of line feed is reduced by costheta times to eliminate the gap between lines.
