Title: Hydraulic drive circuit of running machine
Inventor: MATSUNAMI KATSUOMI
IPC: B62D11/04
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To facilitate straight run and turning of a roll press machine and prevent the running speed of a roll press machine from varying large when changing-over is made from the condition out of differential lock to the differential locked condition or vice versa. SOLUTION: Pistons of radial piston motors 2 arranged symmetrically to the left and right are divided into a first piston group 13 and a second piston group 14, and independent ports 16, 17, 18 are provided. The first groups of pistons 13 of the two motors 2 are coupled parallel always with a hydraulic pump 19, and the second groups of pistons 14 are coupled through a selector valve 24. In the condition out of differential lock, the two sides of second piston groups 14 are made in series by means of changing-over of the selector valve 24 and made parallel in the differential locked condition so as to facilitate a straight run and turning, whereby the change in the rate of flow lessens and the running speed remains unchanged to any large extent because the parallel-series connections of the second groups of pistons 14 are solely changed.

Title: Carrier particle for immobilizing redispersible physiologically active material
Inventor: WATANABE TETSUO
IPC: C12N11/08
Filed: 1987-02-09
Abstract: PURPOSE:To obtain a carrier for immobilizing a physiologically active material which has superior redispersibility by emulsifying and polymerizing an acrylic acid derivative, an acrylic acid fluoroalkyl ester derivative, etc. CONSTITUTION:The acrylic acid derivative shown by a formula >>R<1>CH=CR<2> COOH] is used. Here, R<1> is a hydrogen, alkyl, carboxyl group and R<2> is a hydrogen, alkyl group. Further, the acrylic acid fluoroalkyl ester shown by a formula >>CH2=CR<3>COOR<4>(CF)nCFA2] is used. Here, R<3> is a hydrogen, alkyl group, R<4> is -(CH2)m-, etc., and (m) is 0-12. This acrylic acid derivative, acrylic acid fluoroalkyl ester, and a vinyl copolymerizing monomer, etc., are emulsified and polymerized. Thus, a water-dispersion type polymer particle which has a carboxyl group of 0.03-5mu in particle size is obtained by the polymerization and used to obtain the carrier for fixing physiologically active material. This polymer particle is used as the carrier, so the physiological active material is immobilized to the carrier with good reproducibility and no cohesion is caused at the time of redispersion.

Title: Ink jet head
Inventor: HIRANO HIROFUMI
IPC: B41J2/05
Filed: 1990-02-07
Abstract: PURPOSE:To increase ink jet speed with reduced jetting energy by constituting the cross section of flow path of a flat part for mounting a heating element and a curved part opposing to the heating element and conforming to the profile of bubble. CONSTITUTION:Upon power supply to a heater board 11, a heating element 11a is heated to produce a bubble. When the bubble 15 grows to contact with the curved part of a top board, the curved part 15a of the bubble 15 matches with the curved part 13b of a flow path 13 which is thereby filled with the bubble 13. At this time, ink 16 on the nozzle side is blocked perfectly by the bubble 15 and subsequent expansion of the bubble 15 produces a force effectively in the ink 16 jet direction. Since growth of bubble is utilized effectively for production of ink jet force, ink jet speed can be increased with reduced jetting energy.

Title: Image icon preparation device and its method and record medium storing image icon preparation program
Inventor: AYAKI KENICHIRO
IPC: G06F3/0481
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To prepare an image icon in a relatively short time with a small memory using amount. SOLUTION: In the image data recording area of an image file, other than main body image data for indicating main body images, image data for indicating the thumbnail images (reduced images) of the main body images are stored. At the time of preparing the icon of the main body image, the thumbnail image data corresponding to the main body image are read from the image data recording area. The thumbnail image data are thinned and data for indicating the image icon are prepared. Since the data amount of the thumbnail image data is less than the data amount of the main body images, the time of preparing the image icon is shortened and a memory amount to be used is reduced as well.

Title: Gas range cover plate and its manufacturing method
Inventor: TORIYAMA AKIRA
IPC: F24C15/14
Filed: 1985-02-14
Abstract: PURPOSE:To provide gas range cover plates which can be adapted to a wide range of use at a reduced cost by forming multiple waved ribbs at rounded corners in the inclined side wall. CONSTITUTION:The base material of the gas range cover plate is made of 20mu thick aluminum sheet 10, and its overall plain view is a square with rounded corners 16, 16. There is a hole 13 for gas burner in the center of the bottom 17. The side wall 15 is inclined, expanding to the above, and has no horizontal flange in its upper rim. Since said side wall 15 has multiple waved ribbs 18, 18 in respective rounded corners 16, 16, the ribbs 18, 18 have a bellows-like function, allowing an easy adjustment of inclination angle of the side wall 15. Therefore, even if there is a difference in the size of the gas heater to a certain degree, the cover can easily be fitted to the gas heater by adjusting the inclination angle of the side wall, which is a great advantage for a wide range of use. Further, 10-20 sheet of them can be formed at a time.

Abstract: PURPOSE:To prevent an IP from being damaged and also to reduce a driving load by providing a guide member guiding a recording sheet IP to the aperture of a containing magazine of a spot shorting device and a flexible member brought into contact with this guide member. CONSTITUTION:When a photographed IP 11 is sent to the upper part of an opening part 65a of a storing magazine 65 by a feeding mechanism art 63, a retaining plate 66 is pushed downward by the action of a pressing mechanism part 67, therefore, it works so as to push the IP 11 into the aperture 65a. In such a case, when the IP 11 guided by a guide member 71 and pushed downward is brought into contact with a flexible member 72, this flexible member 72 is bent easily, therefore, the IP 11 is further pushed in by the retaining plate 66, by which it is stored and laminated in the storing magazine 65 from the aperture 65a.

Title: Cassette holder for tape player
Inventor: TSUDA SHIGERU
IPC: G11B15/675
Filed: 1987-02-12
Abstract: PURPOSE:To securely enable a cassette autoloading by providing a spring-like member for the bottom plate of a cassette holder and energizing the cassette upward. CONSTITUTION:When the cassette 20 is inserted into the cassette holder 1, a tip of a cassette stopper 3 provided on the cassette holder 1 bottom part is allowed to contact with a bottom part of the cassette 20. At that time, the space between the tip of the cassette stopper 3 and the cassette holder 1 upper surface is lower than the height of the cassette 20, so that the cassette stopper 3 is pressed by the bottom part of the cassette 20, and hence the elastic member 4 supporting the bottom plate 2 of the cassette stopper 3 is deformed and then the cassette stopper 3 is sunk down to the surface of the bottom plate 2. Then, by resiliency of the elastic member 4 under these circumstances, the cassette 20 is energized upward, and consequently a catch hole 21 on the upper surface of the cassette 20 is firmly engaged with a pack catch 8 on the holder side. By its method, at the time of loading a cassette, the cassette can surely be moved.
