Title: Color image data compression method
Inventor: YAMAMORI KATSUSHI
IPC: H04N1/41
Filed: 1993-12-15
Abstract: PURPOSE:To attain efficient compression of color image data whose notation scale exceeds binary with the simple method employing the run length coding compression technology aiming at a conventional binary image. CONSTITUTION:Color information is read in the unit of horizontal lines, and a comparator means 32 compares the read color information with that of a preceding line as to whether or not they are identical to each other. Then a same color discrimination means 33 discriminates whether or not all pixels have the same color, a compression arithmetic means 34 counts number of pixels in the compression unit being consecutive pixels having same color information, replaces the count into a numeral or bits having specific values whose number is equal to the pixel number. Then the processing is sequentially repeated as to all compression units in the horizontal lines to generate compression data, and finally a data length comparison means 35 compares a compressed data quantity with a data quantity before compression and when the compression data quantity is not less than the data quantity before compression, the data before compression are adopted for compressed data in this color image data compression method.

Title: Absorption type air conditioner
Inventor: NOMURA NAOTO
IPC: F25B15/00
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To effectively prevent an absorption liquid from being crystallized on a solenoid valve for heating operation or on a solenoid valve for a refrigerant by providing circulating flow passages for a heated absorption liquid between a plunger, which is energized by an electromagnetic force of an electromagnetic solenoid to be actuated, and an inner peripheral wall of a cylindrical body containing the plunger. SOLUTION: A plunger 7 to which power is supplied during heating operation has a spherical valve body 66 attracted by an electromagnetic force to be set at an upper position and to open a valve port 64. An absorption liquid heated by a high-temperature regenerator 1 flows from an upstream side pipe 61 to a downstream side pipe 62. Since a notch 72 and an axial groove 73 are opened with a large gaps, a liquid film is not formed, and a circulating stream of the heated absorption liquid is caused in circulating flow passages of the notch 72 - a shaft hole 71 and a gap 69 - the axial groove 73. A U-turn stream which occurs in the gap 69 causes a guide stream even in a narrow gap between the plunger 7 and an inner peripheral wall of a cylindrical body T to prevent the absorption liquid from staying between the plunger 7 and the inner peripheral wall, thereby producing no crystallization.
