Patent JP-H01163422-A (JP)
Title: Rotary piston engine
Inventor: KIDA TATSUYA
IPC: F02B53/08
Filed: 1987-09-14
Abstract: PURPOSE:To enable compressed air to be sufficiently supplied, which is required by an operating chamber for scavenging at the time of exhaust stroke by providing the outer circumferential periphery section of a rotor with a cut-out section which communicates the feeding port section of a compressed air passage with a space within a housing. CONSTITUTION:Since the feeding port section 42 of a compressed air passage 40 is arranged at the specified position of a side housing 14, the period of time wherein the feeding port section 42 is communicated with an inlet stroke work chamber 26a, is shortened. The compressed air passage 40 is restrained to be negative in pressure because of inlet negative pressure. This constitution thereby avoids effectively sucking exhaust gas into the compressed air passage 40 in an exhaust stroke to be processed next. In addition, a cut-out section 45 is provided for the outer circumferential periphery section of a rotor 16, the feeding port section 42 is communicated with the inner space of a housing at least for the period of time when the apex section Q of the rotor 16 is passing through an exhaust port 27. Owing to this constitution, compressed air for scavenging is sufficiently supplied to an exhaust stroke work chamber 26c.

IPC: E21F5/20
Filed: 1993-09-16
Abstract: PURPOSE:To promote dust absorbing performance by forming a spiral air current turning along side walls of a tunnel in a face section and, at the same time, absorbing the air current in a suction port provided on the axis thereof. CONSTITUTION:An exhaust blower 5 and an air blower 9 are operated, and a spiral curve C is formed of turning force by an air current B blown from an air-pipe 8 and absorption force by an suction port 4. After that, the air-pipe 8 and suction port 4 are so arranged that the front end of the spiral curve C comes near particulate matter A generated in a face 2. The particulate matter having a high density is caught in the spiral curve C and is absorbed with the suction port 4, and it is conveyed to the outside of a tunnel through a dust collector 6. According to the constitution, the particulate matter can be collected in a state of a high density before it is spread around a working area and, at the same time, safety can be promoted, it can be efficiently collected with a simple equipment, and costs can be reduced.

Title: Magnetic storage body
Inventor: NAKAGAWA TETSUO
IPC: G11B5/64
Filed: 1985-10-16
Abstract: PURPOSE:To improve the corrosion resistance of a protective film by forming a thin film consisting of at least >=1 kinds of materials selected from an oxide, nitride, carbide, and carbon and further coating a material consisting of the salt of a fatty acid and metal selected from Li, Na, K, Mg and Ca and having >=80 deg.C m.p. on the surface of the thin film. CONSTITUTION:The thin film consisting of at least >=1 kinds of materials selected from the oxide, nitride, carbide, and carbon is formed on a metallic medium and further the metallic salt of the fatty acid having the properties entirely different from the properties of the thin film is coated thereon. The metallic medium is thereby protected against corrosive environment such as water, and in addition, the metallic salt excels in plastic flow deformability and has, therefore, the high effect of decreasing the wear between a storage medium and head. Since the metallic salt having >=80 deg.C m.p. is selectively used, the effect thereof is not lost particularly at a high temp.

Title: Method for authenticating digital image displayed on video monitor and method for composing 1st and 2nd digital images into one composite digital image
Inventor: KNOX KEITH T
IPC: G06T1/00
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To authenticate a digital image according to whether or not the digital image is changed by embedding an authentication mark in the digital image, displaying it and viewing the authentication mark. SOLUTION: Digital images A and B are represented with the number of optional bits for every pixel, and a gray scale image is represented with one byte/pixel. The gray scale image is further stored as a bitmap image file having many pixels or a raster image file and the stored digital images A and B are analyzed one pixel by one starting from pixels 16 and 18 of the respective digital images and compose the images into a single digital output image. This composed 8-bit output pixel 26 is copied to an output image buffer 28. Thus, the image A being the original digital image has the image B of an authentication mark or pattern embedded in it. Therefore, if the digital image is changed, the authentication mark is also changed and the image A is not a genuine image but actually becomes an altered one.

Filed: 1984-10-31
Abstract: PURPOSE:To prevent shocks upon meshing between a pinion and a ring gear, from being transmitted to an end frame, in a starter for internal-combustion engines, by disposing a resilient member between an armature shaft and the end frame. CONSTITUTION:Upon energization of an electromagnetic clutch 12, a lever 13 is pulled to advance a pinion 3a through an overrunning clutch 3, and therefore, a starter motor 20 is driven just before a ring gear 18 is made in contact with the pinion 3a.

Title: System and device for setting path for communication network
Inventor: OKANOUE YASUYO
IPC: H04L1/22
Filed: 1992-08-31
Abstract: PURPOSE:To attain path setting by means of distributed automatic routing in operation by avoiding looping due to a negative ACK when a return message forms a ring state and avoiding transmission of a same retrieval message to a same line for several times. CONSTITUTION:A node at one end of a setting path is set to be a sender along an optional routing and a node at other end is to be a chooser. When the sender detects a path setting command, the sender broadcasts a retrieval message to an adjacent node having an idle band over a path band to search an available path setting circuit. The chooser generates a return message upon the receipt of the retrieval message and the path is reserved by sending back the return message to the sender. Upon the receipt of the return message, the sender generates a link message, and its link message is sent back to the chooser to form a path. Furthermore, an ID of a path to be set is added to the messages as above.

Title: Detecting device for linear component
Inventor: SAITO HIROSHI
IPC: G06T7/60
Filed: 1987-09-17
Abstract: PURPOSE:To prevent the misdetection of a linear component by subtracting all histogram frequencies on a mapping function curve passing through the peak point of the histogram for updating the histogram when the peak point of the histogram produced from the mapping function value is detected. CONSTITUTION:An edge detecting part 22 extracts information on an edge component point out of the signal of an image input part 21 and a function value calculating part 24 applies Hough transformation to the subtracted information. Then a histogram production part 26 produces a 2-dimensional histogram and writes this in a histogram memory 27. A peak detecting part 32 detects a peak point and compares this point with a prescribed threshold value via a deciding part 33 for decision of a straight line. When the part 32 decides a straight line, a histogram updating part 35 subtracts all histogram frequencies that pass through said peak point and performs the updating of histograms. This operation is repeated so that all linear components included in the images are detected with high reliability.
