Title: Joule-thomson cooling type infrared detector
Inventor: SATOU NORITOMO
IPC: H01L31/02
Filed: 1991-12-05
Abstract: PURPOSE:To obtain a Joule-Thomson cooling type infrared detector suppressing a noise caused by fluctuation of a cooling temperature by providing a plurality of foaming blocks with through holes between a high-pressure gas injection nozzle and an inner tube tip wall. CONSTITUTION:High-pressure argon gas is blown out from a nozzle 26 under control of a needle valve 32 so as to be blown against foaming polyethylene blocks 40 to gradually cool the polyethylene blocks 40 and the inner tube tip wall 4a in contact therewith down to a liquefaction temperature 88K. Then, gas is liquefied almost simultaneously with its blowout from the nozzle 26 and a part thereof reaches the inner tube tip wall 4a through the through holes 40a, however, almost all liquefied argon is held inside the foaming polyethylene blocks 40 so as to be prevented from collecting in the tip side lower part of the inner tube 4. Accordingly, since the temperature of the inner tube tip wall 4a is made uniform due to an insulation effect of the foaming ployethylene blocks 40, a noise of an infrared sensor 8 due to fluctuation in a cooling temperature can be suppressed.

Title: Centrifugal fluidizing crushing method
Inventor: IKEDA MITSURU
IPC: B02C17/04
Filed: 1987-12-22
Abstract: PURPOSE: To safely and surely pulverize various materials by feeding low-temp. gas and dry ice into a device equipped with a rotary tray and an outer peripheral ring which is stationary thereto or rotates relatively thereto and maintaining a pulverizing region at a low-temp. atmosphere. CONSTITUTION: Raw materials are fed from a feeding pipe 12 into the device. As the rotary tray 6 rotates, balls 23 execute spiral progression motion by the synthesis of the circular motion circulating the inside wall surface of the outer periphery ring 7 and the tray surface and the revolving motion around the axial center of the rotary tray 6 and the raw materials are pulverized therebetween. At this time, the gas introduced from a low-temp. gas introducing pipe 18 into a low-temp. gas introducing chamber 19 and a bottom cover 20 flows through a clearance 19 and a small hole 15 into a pulverizing chamber to maintain the pulverizing region at the low-temp. atmosphere. The gas is accompanied by the powder generated by the pulverization and is sent from a duct 14 to a classifying means or the like.  The raw materials are uniformly made into the low temp. at the time of pulverizing in such a manner and, therefore, frictional crushing is made easier and the efficient pulverization is executed.

Title: Picture reducing system
Inventor: KIMURA TOSHIHIKO
IPC: G06T3/40
Filed: 1988-12-21
Abstract: PURPOSE:To obtain a comparatively clear reduced picture by executing the reduction of the picture with a reduction run length encoding sequence and setting a run length after reduction to 1 even in the case of a minimum. CONSTITUTION:The reduction of the picture is executed by multiplying magnification to the run length sequence in a run encoding area. Next, when an (n)-th index of the run length sequence is '0' after the multiplication of the magnification, the run length of the (n+1)-th index is suitably divided into the (n)-th index and the (n+1)-th index and processing is executed so that the (n)-th index of the run length 1 can be the runlength 1 or above. The division of a picture element is executed to the index, for which the run length is wholly 0. Thus, the deletion of a picture element linking area can be suppressed and the reduced picture of comparatively small degradation can be obtained.

Title: Light valve
Inventor: KAWAHARA HIROSHI
IPC: G03B27/32
Filed: 1990-11-27
Abstract: PURPOSE:To prevent the peripheral part of a hard copy from becoming dark and to eliminate an effect caused by the shadow of a light shielding layer by irradiating a photosensitive recording medium while an illumination system and an optical shutter are relatively moved in the case that the photosensitive recording medium is exposed according to an image signal impressed on the optical shutter. CONSTITUTION:In the case that the photosensitive recording medium is irradiated and exposed by the illumination system L through an optical shutter array 51, it is exposed while the illumination system L and the array 51 are relatively moved. When the scanning of image data formed on the array 51 is finished, a latent image as much as one part of an original picture is formed on the photosensitive recording medium. Since the array 51 is almost uniformly irradiated from one end to the other end during the scanning, the peripheral part of the photosensitive recording medium is also sufficiently exposed. Besides, in the case that the light shielding layer is irradiated, the top part of the moving irradiating light obliquely enters a shadow part formed by the light shielding layer and the first half part of the shadow is exposed. Then, the second half of the shadow of the light shielding layer is exposed by the back end part of the irradiating light. Thus, the insufficient coupling of a picture element caused by the shadow of the light shielding layer is prevented from occurring.

Title: Method for detecting white line
Inventor: ONO TAKASHI
IPC: G06T7/00
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To allow the white line detection method to deal with all traveling roads by measuring a luminance value in each search area, discriminating a road face from a white line and detecting the white line. SOLUTION: An initial search area A1 for detecting a white line 6 is set. The search area A1 is expressed by straight line of a prescribed length in the vertical direction of a screen. Luminance is measured in the range of the area A1. When the distribution of luminance in the area A1 is found out, a part having a sharply high luminance value is detected when the white line 6 exists. The point of the high luminance value is left as the white line 6. A search area A2 is similarly set up at a prescribed interval from the point in the horizontal direction. In a 3rd and succeeding search areas, each search area is inclined in the direction of the curved white line 6 and set so as to be at always a right angle to the white line 6. Thus each search area is brought close to the white line 6, and even when the search area of the white line 6 is set from the left side of the screen, the method can deal with both of right and left curves.
