Title: Marking method
Inventor: YAMAGISHI TADASHIGE
IPC: B41F17/28
Filed: 1989-03-20
Abstract: PURPOSE:To efficiently apply a marking of characters or symbols on products of a multikind and small lot without deteriorating the smoothness of a marking surface by a method wherein a medium applied with a thermally migrating ink is brought into close contact with the marking surface, a vibration energy is transmitted to the medium, and the ink is heated to a thermally transition temperature by a frictional heat. CONSTITUTION:A predetermined key top 7 is disposed downward of an ultrasonic generator 2. A film 1 is moved downwards by a drive mechanism to be brought into contact with a marking surface 7a of the key top 7. The ultrasonic generator 2 is moved downwards to press the film 1 to make the film 1 in close contact with the marking surface 7a. Then, ultrasonic waves are generated, and an ultrasonic vibration energy is transmitted to the film 1. A frictional heat is generated by this energy, thereby heating the thermally transition ink on the film 1 to a thermally transition temperature. The ink reaching the thermally transition temp. melts and transfers to the key top 7 which is in close contact therewith, furthermore penetrating into the key top 7. Then, the marking is completed.

Title: Fuel supply apparatus for internal-combustion engine
Inventor: MORI YASUSHI
IPC: F02D41/00
Filed: 1984-04-09
Abstract: PURPOSE:To prevent engine stalling by calculating the number of revolution with which the initial explosion after the recovery of fuel supply occurs before the reduction of the engine speed to the min. engine speed where engine stop is not generated, and setting said engine speed as the number of recovery revolution, in case of fuel cut in deceleration. CONSTITUTION:When it is detected by an idle switch 8 that a throttle valve 3 is in perfectly closed state and the engine speed N calculated 11 from the output of a crank-angle sensor 9 is larger than the engine speed Nc in fuel-cut judgement, the deceleration speed is calculated 13, and the second engine speed N2 is calculated 15 from the deceleration speed and a prescribed revolution angle. Then, N2 is set equal to Nr (number of recovery revolutions), and Nr is compared with the engine speed N by a comparing means 16, and if N>Nr, fuel cut is continued. In this case, the above-described prescribed revolution angle is set as the crank-angle revolution angle formed through the path ranging from the fuel injection after recovery to the initial explosion which is obtained from the previous experiment.

Abstract: PURPOSE:To obtain the subject compound existing as a communicating substance of insects in the natural world in high optical purity in a short step by using an inexpensive and readily available D-ribose as a starting substance and carrying out reaction such as oxidation and reduction. CONSTITUTION:D-Ribose expressed by formula I is made to react with an acetalizing agent to protect hydroxyl groups at the 2- and the 3-positions and the resultant protected D-ribose is subsequently allowed to react with an organometallic reagent to afford a compound expressed by formula II (R is 2-10C alkyl; R<1> and R<2> are protecting group of OH). The 1,2-diol part of the compound expressed by formula II is then oxidatively cleaved, simultaneously cyclized and further oxidized. The protecting groups at the 2- and 3-positions and hydroxyl groups are released to afford a compound expressed by formula III. The double bond between the 2- and the 3-positions in the compound expressed by formula III is reduced in a hydrogen atmosphere in the presence of a hydrogenating catalyst (e.g. Raney nickel) to provide the objective (S)-gamma- lactone expressed by formula IV.

Title: Fixing device for middle part of outside cable
Inventor: SUZUKI AKIYOSHI
IPC: E01D2/00
Filed: 1994-04-07
Abstract: PURPOSE:To enhance the effect of a pre-stress by securing an outside cable in which the pre-stress is introduced in the main cross-beam of a bridge in its longitudinal direction to the middle part of a beam in such a way that the cable is not moved and deflected in its longitudinal direction by means of fixing devices. CONSTITUTION:An outside cable 4 in which a pre-stress is introduced in the main cross-beam 1 of concrete in its longitudinal direction is secured to the middle members 2 of a beam 1 in such a way that the outside cable 4 is deflected and is not moved in its axial direction through fixing devices 6 consisting of fixing members 15 having connecting bars 10, taperings 18. In introducing the pre-stress in the outside cable 4, external force is acted on the main cross-beam 1 even at an intermediate portion as well as both ends to give almost the same distortion as that of the major cross-beam 1 to the outside cable 4. The result facilitates the mounting of the outside cable and enhances the breaking-proof stress of the major cross-beam against an impact load.

Filed: 1983-04-19
Abstract: PURPOSE:To increase life and energy density of a lead-acid battery by using a current collector comprising moldings of a mixture of lead oxide and an acid resistant and oxidation resistant binder. CONSTITUTION:Lead oxide powder indicated as PbOn (n=1.3-2.0) is mixed with an acid resistant and oxidation resistant binder such as synthetic resin, water- glass, or phosphate and they are molded in desired form and dried. A current collector for lead-acid battery obtained by this process has low density compared with a conventional lead alloy current collector and provides light grid. Since progress of oxidation is prevented, no volume expansion or breakdown is provided. Therefore, energy density and life of the lead-acid battery using this current collector are increased.

Title: Method for preventing air from being entrapped during manufacture of laminated steel plate
Inventor: TERASAKI NORIO
IPC: B32B15/08
Filed: 1987-03-23
Abstract: PURPOSE:To obtain a laminated steel plate having an even outer surface excellent in flatness by reducing the air flow accompanied by a running sheet and consequently preventing the air from being entrapped between the substrate and the outer surface of the laminated steel plate by a method wherein the angle between the sheet and the steel band is controlled. CONSTITUTION:When a sheet, which consists of a resin film and/or a metallic foil or their prelaminates, is laminated to a steelband, the sheet is fed toward the steel band under the state that the angle between the sheet and the steel band is held at 30-90 deg.. The amount of air caught between respective laminated layers closely relates to the angle theta of approach of the resin film or metallic foil to the steel band. If the angle theta of approach is small, the rate of diminution of the resultant space sectional area S becomes small and the rise of circulating resistance of air in the direction of a press roll 3 decreases by that rate, resulting in increasing the amount of the air accompanied by the sheet 1. On the contrary, if the angle theta of approach is large, the space sectional area S rapidly decreases toward the press roll 3, resulting in developing rapid rise of circulating resistance of air. As a result, the air between the steel band 2 and the sheet 1 is discharged sideways to free space and no air reaches the press roll 3.

IPC: G01R31/302
Filed: 1986-03-29
Abstract: PURPOSE:To enable the use of a small capacity low speed vector memory and to enable the stable operation of a LSI chip being a simulation object, by forming a lead signal and a second reference clock, etc. on the basis of a reference clock by a control part according to a hardware system. CONSTITUTION:When a start signal X is applied from a host calculator 1, the frequency of a reference clock phiC is divided by a control part 4 to form a second reference clock CLK and a read signal RD having phase difference such as one cycle of the clock phiC with respect to said clock CLK. Simulation input is read from a vector memory 3 corresponding to the signal RD to be supplied to a LSI chip 2 controlled by the clock CLK. By the formation of the clock CLK and the read signal RD by a hardware, a reference clock is stabilized and formed by a forming source different from an input vector train forming source and the phase difference thereof can be set to a predetermined value without increasing vector quantity. By this constitution, the capacity of the vector memory can be reduced and the speed thereof is decreased and LSI being a simulation object operates stably.
