Title: Picture data compression method
Inventor: NAKANISHI HIDETOSHI
IPC: H04N19/186
Filed: 1991-12-20
Abstract: PURPOSE:To suppress picture quality deterioration in a decoded picture and to reduce data quantity to be saved without need of plural stages of arithmetic operation taking a difference between an original picture and an expanded picture over the entire picture area. CONSTITUTION:Original picture data Do are compressed to obtain compressed picture data Dc, the compressed picture data Dc are expanded to obtain 0-th expanded picture data Dr0. Then a 1st low picture quality area is extracted based on the original picture data Do and the 0-th expanded picture data Dr0, a difference between the original picture data Do and the 0-th expanded picture data Dr0 is compressed within the low picture quality area to obtain a 1st compression differential data Dd1. Furthermore, expansion differential data obtained by expanding the 1st compression differential data Dd1 and the 0-th expanded picture data Dr0 are added to obtain 1st expanded picture data Dr1. Thus, the processing to obtain the compressed differential data in which the picture of a low picture quality area reaches a prescribed picture quality rank or over is repeated in this way.

Filed: 1992-12-24
Abstract: PURPOSE:To reduce the thickness of an ozone filter without increasing its pressure drop and without degrading the cracking capacity of the ozone filter by using the ozone filter having meshes inclined in a flow direction of air with its thickness direction. CONSTITUTION:The meshes of the ozone filter 17 are so formed as to incline with the thickness direction of the ozone filter 17 and are consequently so set that the air passing the ozone filter 17 inclines with the thickness direction of the ozone filter 17. The ozone filter 17 is so formed that the number of its meshes is the same as the number of the meshes of the conventional ozone filters. The formation of the ozone filter 17 to the thickness smaller by (a-c) than heretofore is, therefore, possible, if the same air passage distance as the air passage distance of the conventional filters, i.e., the same ozone removal efficiency as the ozone removal efficiency of the conventional filters are to be obtained with the ozone filter 17. Then, the formation of a suction filter to a relatively large thickness is possible as well.

Title: Screw pipe for steep-slope section sewage pipe
Inventor: HIROSE MAMORU
IPC: F16L11/12
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To facilitate the execution of works by bending and forming a sewage pipe in a spiral type. SOLUTION: The front end of an upper section is extended linearly on the tangent of the screw pipe, the inclination and spiral diameter of the whole screw pipe are determined, and the pipe is machined. A lower-section front end is elongated linearly on the tengent of the screw pipe, and the screw pipe 1 for steep-slope sewage is prepared. Flow velocity in the pipe is controlled by changing the number of the stage of the winding of a spiral or altering the diameter of the spiral when the inside diameter of the pipe is kept constant. Or sewage can be flowed down naturally from a vertical section to a steep slope section while holding required flow velocity because flow velocity can be adjusted by varying the axial angle of the whole spiral.  Accordingly, a sewage pipeline on a precipice place or the steep slope section can be laid only by the spiral pipeline, the laying is executed easily, and construction cost is also reduced by a section, in which no manhole is needed in an intermediate section. Since a joining section by conventional stepped sections is removed and the flowing-down of sewage is brought to a continuous and uniform-flow state, solid bodies are flowed down simultaneously and smoothly.

Abstract: PROBLEM TO BE SOLVED: To provide a main rope replacing method for a 2:l-roping elevator that allows smooth replacement of a main rope without causing kinks of a newly installed main rope. SOLUTION: After a rope looping process in which a newly installed main rope 10 unreeled from a drum 11 placed on a floor 3 is looped over a pulley 15 on a car 4 and also over a sheave 16 placed in a machine room 2, the leading end 10a of the main rope 10 is secured to a machine room floor 17 by way of a thimble rod 19a with a rope unkinking mechanism 19 and the U-turned section 10b of the main rope 10 is guided down to a counterweight 7 by a main rope mounting jig 20 attached movably to guide rails 8. The method thus causes fewer kinks of the U-turned section 10b of the main rope 10 and also absorbs kinks of the main rope 10, if any, with the rope unkinking mechanism 19.

IPC: F24F3/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain air-conditioning equipment where air-conditioning is made appropriately on cooling and heating, and internal pipe structure is simple. SOLUTION: Parts 8 and 9 under a floor are provided below floor panels 2 and 4 of first and second floors and a floor ventilation port 16 is opened at each floor panel, thus connecting a duct 18 for a part under the floor. A ceiling ventilation port 17 is opened on ceilings 3 and 5, thus connecting a ceiling pipe 19a and a duct 19 for ceiling. In the ducts 18 and 19, branch pipes 18b1 and 19b1 for feeding and return branch pipes 18b2 and 19b2 and then a feed damper 21 and a return damper 22 are connected to an air-feeding port 25a and a suction port 24a, respectively, of air-conditioning equipment 23. A low-temperature and high-temperature heat medium is allowed to flow to a heat exchanger 25 of the air-conditioning equipment 23 on cooling and heating, respectively.  Although a cool wind is supplied from the ceiling duct 19 on cooling and is returned from the parts 8 and 9 under the floor via the duct 18, the floor panel cannot be excessively cooled below a room temperature. On heating, a warm wind is allowed to flow in an opposite path. At this time, the floor panels 2 and 4 are heated due to the flow of a warm wind whose temperature has not decreased in the room, thus heating the floor.

Title: Card-operated laundry equipment
Inventor: HIROSE HISANORI
IPC: D06F39/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent the amount data of a card from being reloaded although drying operation is not executed, and to eliminate a chance not to reload the amount data of the card although the drying operation is executed. SOLUTION: Before an operating command signal for starting a drying operation is sent out, a card microcomputer 34 sends a communication confirmation signal to a drying mechanism microcomputer 26. In response to the communication confirmation signal, the card microcomputer 34 receives a communication enable signal sent from the drying machine microcomputer 26 so as to judge that bidirectional communication with the drying machine microcomputer 26 is enabled, and an operating command signal is sent to the drying machine microcomputer 26. When the card microcomputer 34 does not receive the communication enable signal, on the other hand, no operating command signal is outputted from the card microcomputer 34 and neither drying operation nor the reloading of the data on the card is performed.
