Title: Garbage container transport system
Inventor: WATANABE IPPEI
IPC: B65G51/02
Filed: 1987-06-23
Abstract: PURPOSE: To increase transport driving force without increasing the quantity of ventilation at the above transport system based on air current by making the inside diameter size of the rising portion of a transport pipe smaller than that of the horizontal portion thereof.  
     CONSTITUTION: The inside diameter size of the rising portion 3 of a transport pipe 1 is set smaller than that of the horizontal portion 4 thereof. As a result, the flow speed of air in the rising portion 3 becomes larger than that in the horizontal portion 4, and ventilation resistance increases, and the pressure difference per unit length in the rising portion 3 becomes larger than that in the horizontal portion. Accordingly, driving force in the rising portion 3 can be increased in comparison with driving force in the horizontal portion 4.

Title: Image forming device
Inventor: YAMAMURA TOSHIKI
IPC: H04N1/40
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To apply gradation processing to both image areas of an image and a background automatically by separating the image area from the background area so as to generate a density change of binary image data by a pseudo halftone. SOLUTION: A halftone arithmetic section 1 (106) sums binary background area data stored in a surrounding pixel storage section 1 (105) with each other to detect a pseudo halftone density of a range. A binarizing circuit 1 (107) binarizes the halftone density calculated by the halftone arithmetic section 1 (106) and gives the result to an area discrimination section 1 (103) and a selection section 1 (104) as background arithmetic data. A mask section 110 compares a threshold level fed from a CPU 101 with data converted into a pseudo medium tone density. When the pseudo halftone density data are larger than the threshold level, the range is discriminated to be an 'image area' and when the threshold level is larger, the range is discriminated to be a 'background area'.

Filed: 1985-07-15
Abstract: PURPOSE:To improve the effective application factor of a cache memory at an arithmetic part by providing the 1st and 2nd address registers and a comparator which compares the contents of both address registers with each other. CONSTITUTION:When an address strobe signal is received, the address information is held by an address register 220 and compared with the contents of an address register 210. If the address information has the same block as the address stored in the register 210, the coincidence signal 251 is set at 1. While the signal 251 is set at '0' if no coincidence is obtained between said address and address information. Then no cache application request signal 252 is outputted when the coincidence is obtained. In other words, no cache memory is used. When no coincidence is obtained, an application request is outputted for the cache memory. Then it is checked whether the cache memory has a block corresponding to the relevant block or not. If exists, the block is invalidated.

Title: Lithoclastic agent
Inventor: ISHII SHIRO
IPC: A61P13/02
Filed: 1985-07-18
Abstract: PURPOSE:To obtain a lithoclastic agent producible easily, insertable easily in bored hole of a calculus, capable of breaking the calculus by dilation pressure and having high safety, by using a dilation material developing dilation pressure by the hydration reaction with water, ad kneading the agent with an organic solvent. CONSTITUTION:A dilation material developing dilation pressure by the hydration reaction with water (e.g. static disintegration agent, dilation material for cement concrete, quick lime, calcined dolomite, etc.) is kneaded with an organic solvent (e.g. methanol, ethyl ether, acetone, etc.) to obtain a solid lithoclastic agent easily. A lithoclastic agent having high handleability and insertable easily into the bored hole of a calculus can be formed by forming the dilation material in the form of rod, table, etc., using the organic solvent as a binder. Since the dilation pressure develops slowly according to the elapse of time, the calculus can be broken without generating gases and shock wave in contrast with the case using an explosive as a disintegration agent, and accordingly, the agent has excellent safety.
