Patent JP-H0419201-A (JP)
Title: Radial tire
Inventor: NAKAGAWA SUMUTO
IPC: B60C9/18
Filed: 1990-05-11
Abstract: PURPOSE:To improve belt end separation resistance by providing a cobalt plated layer on the surface of a single steel wire of a specific wire diameter, and forming its covering rubber of a rubber composition containing a specific quantity of organic cobalt metalic salt and sulfur, with its 100 % modulus after curing to be more than the specific value. CONSTITUTION:A single steel wire of 0.50mm in wire diameter is used for the belt crossed layer of a radial tire, and the outermost layer surface of the steel cord is covered with cobalt plating. The quantity of sulfur in the covering rubber is specified to be 0.5-4.0 weight parts to 100 weight parts of rubber components, and organic cobalt salt in the covering rubber is specified to be less than 0.1 weight parts as cobalt metal. The modulus of the covering rubber is further specified to be more than 20kg/cm<2>. The rubber is thereby prevented from head aging caused by the excessive use of sulfur, and its crack growth resistance is improved in large degree. The corrosion fatigue resistance of adjoining steel cords can be also improved by reducing a corrosive component. This results in improving not only corrosion fatigue resistance but also belt end separation resistance.

Title: Copying machine with spread both-side copying function
Inventor: ISHIZUKA TAKASHI
IPC: G03G15/04
Filed: 1987-05-19
Abstract: PURPOSE:To copy 1st and 2nd pages of a book to the top and reverse surfaces of transfer paper correctly by storing the length of the book which is spread on an original platen in a memory and controlling the timing of registration between the reverse surface end part of the transfer paper and the end part of a 2nd page. CONSTITUTION:The book 14 is spread and placed on the original platen 1 and the length of the book 14 is measured on a scale provided on the end part of the original platen 1 and stored in the memory. Then when the pages are copied to the top and reverse surfaces of the transfer paper, a scanner is scanned to A (center position) of length a half as large as the length of the book according to the information in the memory and a top surface copy is made. Then the scanner is scanned from a reference position S to the end position B of the book 14 and a registration roller is so controlled by the memory at the same time that a photosensitive drum where an image of the position A corresponding to the end part of the 2nd page is aligned with the end part of the reverse surface of the transfer paper, thereby copying a toner image on the photosensitive drum to the reverse surface of the transfer paper. Thus, the registration timing is controlled with the length information on the spread book, so the front ends of the original and transfer paper are aligned with each other and the book is copied.

Title: Method and apparatus for measuring profile of tire
Inventor: OCHIAI TOSHIO
IPC: B60C19/00
Filed: 1981-07-31
Abstract: PURPOSE:To measure the profile quickly and highly accurately, by approximately aligning the rotary shaft line of the tire and the center of the cross section of the tire to be tested, rotating the tire, and irradiating a laser light beam from the specified direction. CONSTITUTION:XY tables 14a and 14b are provided on a flat plate 12 which is rotatably supported around the rotary shaft 10 on a supporting table 8. The tire 30 is supported thereon by a supporting post 16. The center A of the cross section of the tire 30 is approximately aligned with the rotary shaft line 0-0. An equator surface U is made in parallel with the rotary shaft line 0-0. Then the tire is rotated by an angle thetamin which is formed by the central part of a tread (not shown) and the bead part, with the rotary shaft line 0-0 as a center. Thereafter the laser light 3 is irradiated from a laser displacement gage 2 on the outer surface of the tire 30. Based on the displacement amount of an irradiated point P and the rotary angle theta, the coordinates of the irradiated point P with the rotary shaft line 0-0 as an original point is computed by an operator 4, and the profile of the tire is displayed on a display 6.

Title: Air valve
Inventor: TAJIRI KAZUMI
IPC: F16K24/00
Filed: 1989-05-12
Abstract: PURPOSE:To obtain compaction by providing a pressure chamber additionally with an elastic body for energizing a valve stem in the direction of closing an exhaust port in a valve body. CONSTITUTION:When exhaust is almost completed and water as a fluid flows into a float chamber 24, a float 22 floats and a guide bar 44 comes in contact with the valve seat 53 of a valve stem 47 so as to close a communicating hole 52. The air therefore stops flowing into a pressure chamber 27, so that the internal pressure becomes the atmospheric pressure, the pushing-down force of the valve stem 47 acting upon a diaphragm 37 becomes extinct, and a valve body 46 ascends by the buoyancy of the float 2 and the restoring force of an elastic body 54 so as to close an exhaust port 34. As the sealing performance of the exhaust port 34 is thus maintained by both buoyancy of the float 22 and restoring force of the elastic body 54, the larger sized float 22 is not needed and even after the exhaust port 34 is closed, the air in the float chamber is compressed by the pressure in a duct, so that the level ascends.

Title: Pallet stocker
Inventor: UCHIDA HIYAKUMA
IPC: B65G47/88
Filed: 1986-05-27
Abstract: PURPOSE:To circulate a pallet alone in one direction and feed a delivery port with a material all the time, by installing a pallet transit unit on each diagonal line of a square track, making it free of disengagement with a pallet and a piston, and rotating it just the opposite while engaging or disengaging the unit to or from the pallet. CONSTITUTION:A pair of pallet transit units 19 and 20 are installed a diagonal line on one side of square tracks 2a-2d, and individual pallet transit units 21 and 22 are installed on the diagonal line one the other. Each of a pallets 15a-15f is mounted free of slide motion on upper edges 7-14 of both inner and outer peripheral walls of the track. Each pallet is made possible to be engaged or disengaged by a piston of the cylinder installed in the transit unit. A material is mounted on each pallet, and when the pallet at a delivery port 17 becomes emptied, each transit unit retracts all pistons and is rotated, chaging each position to a lower part of the adjacent unit, and the piston is projected whereby a new pallet is engaged, thus it is rotated again. Therefore, the pallet alone is circulated in one direction and fed to the delivery port.

Title: X-ray television set
Inventor: HONDA KOJI
IPC: H04N5/32
Filed: 1989-05-16
Abstract: PURPOSE:To reduce an exposure time to an object by allowing readout of a feedback data from a memory section for feedback data to follow a video data inputted from a camera after movement based on the operating data of the movement and rotation of the camera from the camera base. CONSTITUTION:When an operating data of movement or rotation of a camera 1 from a camera base 9 is inputted to a feedback memory control section 11, the feedback memory control section 11 converts a readout address from a feedback data memory section 10. Then the output data from the feedback data memory section 10 is controlled so as to follow a digital data inputted from the camera 1 and outputted from an A/D converter 2 after the movement or rotation of the camera 1. In this case, the positional deviation attended with the operation of the camera 1 is avoided. Thus, the exposure time to an object is reduced.

IPC: G06T15/80
Filed: 1991-05-27
Abstract: PURPOSE:To eliminate the variation of shading display colors owing to coordinate conversion. CONSTITUTION:A frame buffer 6 stores the luminance value of a display point and it displays and coresponds to 16M colors. A Z-buffer 6 stores the coordinate value of the depth direction of a display point. A coordinate conversion means 1 converts the respective vertex coordinate of an inputted convex quadrilateral to a coordinate system peculiar to a device by an inputted coordinate conversion matrix. A luminance value calculation means 2 executes reflection calculation with regard to irradiation light from a light source at respective vertexes constituting the projecting quadrilateral and calculates the vertex luminance value. A triangle division means 3 obtains the luminance value at the intersection of the two diagonals of the projecting quadrilateral by the luminance value interpolation of the diagonal two vertexes of respective diagonals, sets the mean of the calculated two luminance value to be the luminance value at the intersection and furthermore, divides it into, four triangles with the intersection as one of their vertex. A plotting means 4 plots and outputs the group of the triangles to the frame buffer 5 and the Z-buffer 6.
