Title: Method for tension test of tubular test piece
Inventor: NISHIFUJI KATSUYUKI
IPC: G01N3/02
Filed: 1980-09-11
Abstract: PURPOSE:To carry out tension tests of many and diversified kinds of pipes easily and surely without preparing many kinds of mandrels by packing low melting metals respectively in both ends of test pieces. CONSTITUTION:Spacers 6, 6 of sponge, paper or the like are inserted into a tubular test piece 1, ad low melting metals 9 are injected from both ends. When these are cooled, the two end parts of the test piece are packed by the metals 9, 9. Hence, the test piece 1 can be mounted to a tension testing machine via chucking devices 3 without using any mandrel. The packed metals 9 conform to the inside diameter of the test piece 1 irrespectively of the sizes of the test piece 1. The tension tests of many and diversified kinds of pipes are carried out easily and surely by these.

Title: Valve operating device in internal-combustion engine
Inventor: HABU NOBUO
IPC: F01L9/12
Filed: 1983-07-14
Abstract: PURPOSE:To relieve impact upon closing of itake and exhaust valves, by controlling the lift of each of the intake and exhaust valves with the use of the relative angular position between inner and outer cylinder in a valve lifter, and as well by providing a damper chamber between the outer cylinder and the cylinder head. CONSTITUTION:The lift of a cam 10 is transmitted to an intake valve or an exhaust valve 12 by means of a hydraulic lifter 17 which slides in a lifter hole 181 in a cylinder head 18. The hydraulic lifter 17 is composed of bottomed inner and outer cylinders 20, 22 in which a reservoir chamber 32 and a high-pressure chamber 30 are defined. Since a groove 40 is formed in the inside of the outer cylinder 22 while an inclined lead 33 is formed in the bottom section of the inner cylinder 20, the cut-off position of the communication between the high pressure chamber 30 and the reservoir chamber 32 is adjusted by controlling the relative angular position between the inner and outer cylinders through a drive shaft 52, a sector gear 50 and a tooth section 203, and therefore, the lift of the valve is controlled. Further, a damper chamber 70 between the outer cylinder 22 and the cylinder head 18 relives impact upon closing of the valve.

Title: Correcting attachment of long distance photographing in lens shutter camera
Inventor: YAMAKI MICHIHIRO
IPC: G02B15/10
Filed: 1983-07-14
Abstract: PURPOSE:To photograph an object at a long distance more vividly by placing a lens system having a negative power before a photographic lens system to correct the focus for photographing of the object at a long distance. CONSTITUTION:For the purpose of photographing vividly an object at a long distance in an auto-focus lens shutter camera, a fixed-focus lens shutter camera, or the like, the light from the object in the inifinity is refracted by an attachment lens L1 having a weak negative power to form a virtual image of the object in the infinity in a position P of the farthest photographic distance of the camera, and this virtual image is focused onto a film surface F by a photographic lens system L2 of the camera to photograph the object in the infinity vividly. In this case, since a plano-concave and plano-convex lenses different in refractive index are stuck to each other, refractive indexes and radiuses of curvature of stuck faces of them are selected properly to determine the focal length of the whole of the system.

Filed: 1984-06-22
Abstract: PURPOSE:To obtain a printing device having high operability by displaying the name of a face only for a prescribed time, when installing an external storage means which has stored with regard to at least one kind of a character face. CONSTITUTION:First of all, prior to use of a printing device, a face generating external memory 5 of a face to be printed is installed to the device. When the installation of the external memory 5 is confirmed, a control part 4 reads out the contents of a name of a face stored in an address (a) of the external memory 5 through a connecting part 6. Subsequently, the control part 4 displays this face name on a display part 3. At the same time, the control part 4 starts a timer circuit 7 to measre for a prescribed time. The timer circuit 7 informs a lapse of the prescribed time to the control part 4, and the control part 4 erases the face name displayed on the display part 3. In this way, when the external memory 5 has been installed to the body device, the face name is displayed only for a prescribed period, therefore, it is useful for preventing a wrong face from being printed.

IPC: B41C1/02
Filed: 1989-05-19
Abstract: PURPOSE:To improve the unequal ink in shadow parts by constituting one piece of cell group of 9 pieces of cells, continuously forming 8 pieces of the cells enclosing the central cell of each cell group as a nucleus in the form of contiguity of land with two pieces as one set, disposing respective underfill parts point-symmetrically with the center of the respective cell groups and arraying the respective adjacent cell groups so as to deviate from each other by as much as one piece of the cell in a vertical direction and a horizontal direction. CONSTITUTION:One piece of the cell group G1 (G2) is constituted of 3 pieces X3 pieces of the vertical and horizontal cells. The respective underfill parts 3 are point-symmetrical with the center of the group G1 (G2) and the respective adjacent cell groups deviate from each other by as much as one piece of the cell. There is no possibility that the flow of the ink between the cells arrays in, for example, the printing direction (arrow A) in this case. Namely, the chaining of the underfill parts 3 at a specified pitch is obviated and since the flow of the ink between the cells is randomized, the satin-like unequalness in the specified direction of the ink at the time of the printing is less conspicuous.

Title: Transmitting equipment
Inventor: MAEKAWA TAKAAKI
IPC: H01Q1/40
Filed: 1990-05-17
Abstract: PURPOSE:To suppress the current leaking from a drill pipe as low as possible even if the excavation depth becomes deep, and to obtain a receiving signal of sufficient magnitude on the ground by placing an insulator so as to surround the periphery of a transmitting antenna. CONSTITUTION:Underground information obtained from a sensor, etc., is modulated as an electric signal by a modulation transmitter 2, and this electric signal is applied to the upper and the lower electrodes 11, 12 of a transmitting antenna 1. In this case, a current corresponding to the modulated electric signal flows to the ground of the periphery of the transmitting antenna 1. However, by a peripheral insulator provided on the surface of a casing pipe 103, a current leaking to the ground from the transmitting antenna 1 comes to be scarcely generated in the upper part of a cross section A-A' in the figure. Accordingly, as for magnitude of a signal received in a receiving antenna buried in the vicinity on the ground, the potential on a drip pipe increases.

IPC: C22F1/18
Filed: 1977-10-24
Abstract: PURPOSE: To give colorless metallic luster to the surface of Ti or a Ti alloy on which a colored film has been formed by heating to high temp., by heating the Ti or alloy to above 500°C in a vacuum or a high purity atmsophere of an inert gas.  
     CONSTITUTION: When Ti or a Ti alloy is heated to above 300C in an oxidizing atmosphere, a characteristic colored film is formed on the surface. The Ti or alloy colored by the oxidation is heated to above 500°C in a vacuum or a high purity atmosphere of an inert gas such as Ar, whereby oxygen in the film diffuses into the Ti or alloy, lowering the surface oxygen concn. Thus, the colored surface becomes coloress and metallic luster appears.
