Title: Distribution type fuel injection pump for unequal interval injection
Inventor: TANAKA MASAMICHI
IPC: F02M41/06
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To perform the unequal interval fuel injection by a two cylinder engine or the like and to adapt a distribution type fuel injection pump by comprising a cam injecting the fuel at an unequal interval in a device which comprises a distributing mechanism between a plunger and a discharge valve and where a distribution shaft is arranged separately from the plunger. SOLUTION: When a plunger 7 interlocked with the rotation of a cam shart 4, is located on a lower end in a range of the vertical movement range in a condition that the fuel is forced fed to a fuel gallery by a feed pump 6, the fuel, in the fuel gallery is forced fed to a plunger barrel 8. Then when the plunger 7 is pushed up by a cam 5, the fuel in the plunger barrel 8 is forced fed to a delivery valve through a distribution shaft sleeve and a distribution shaft to be injected into a cylinder from a fuel injection valve. On this occasion, as a cam 5 on the cam shaft 4 comprises two cam profiles 21, 21, and a roller 22 rotatably pivotted on a tappet 11 is kept into contact with the cam 5, an interval of the fuel injection is determined on the basis of the shape of the cam 5.

IPC: B23K35/40
Filed: 1981-03-31
Abstract: PURPOSE:To elevate cracking resistance of a welding metal, by performing welding by use of a low-hydrogen type coated electrode having a coating agent which contains a small quantity of hectorite and consists of a caking agent of water-glass having a specific molar fraction of SiO2 and Na2O. CONSTITUTION:When welding dead thick steel without preheating it, a low- hydrogen type coated electrode coated with a coating agent consisting of the following composition is used. That is to say, the electrode to be used is obtained by coating a core wire consisting of soft steel or alloy steel, with a coating agent using water-glass as a coating agent to carbonate, a fluoride, a slag forming agent, a dioxidizer, alloy iron, iron powder, etc. In this case, 0.1-3% hectorite is added to the coating agent, also that which contains water-glass whose molar fraction of SiO2/Na2O is 2.0-2.6 is used, and the coating agent is heated and burnt at 500-800 deg.C in the atmosphere containing CO2 of 2% or  more. A welding metal produced by use of this electrode has excellent cracking  resistance.

Title: Pad for magnetic tape cassette and its production
Inventor: WATANABE MASARU
IPC: G11B23/087
Filed: 1993-03-09
Abstract: PURPOSE:To lower the coefft. of dynamic friction between a pad and a back coating layer and to prevent tape squeaking by flocking plural pieces of fibrous bodies formed in such a manner that the m.p. of the outside layer resin of fluororesin fibers having double structures is made higher than the m.p. of inside layer resins on a base material. CONSTITUTION:The m.p. of the resins in the outside layer of the fluororesin fibers 1 having the double structures is made higher than the m.p. of the resin of the inside layer and these fibers are flocked onto the base material 2. The base material 2 is adhered by a tacky adhesive to a metallic sheet spring 3. Then, the fibers 1 are welded to the base material 1 at the temp. above the m.p. of the inside layer resins and below the m. p. of the outside layer resins. The fibers are flocked by each one piece onto the base material 2 without welding of the fibers to each other even if plural pieces of the fibers are welded to the base material 2. Consequently, the pad has adequate elasticity and a good head touch is obtd. when the pad comes into contact with a magnetic head. As a result, the coefft. of dynamic friction between the pad and the back coating layer of the magnetic tape is lowered and the generation of the tape squeaking at the time of recording and reproducing is suppressed.

Title: Pressure contact connector
Inventor: SAKURAI RIICHI
IPC: H01R13/428
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent a pressure contact terminal fitting from being buckling- deformed when it is inserted into a cavity. SOLUTION: When a pressure contact terminal fitting 20 is normally inserted, a projection 26 contacts with a receiving part 16 at a central position in the direction of its insertion, and pressing force acting on the back end of the pressure contact terminal fitting 20 is received by the receiving part 16. Because the receiving part 16 and the projection 26 is placed at almost central position longitudinally to the pressure contact terminal fitting 20, length of a region where grabbing force act to the pressure contact terminal fitting 20 is about a half of the length of the fitting 20. Therefore, buckling deformation his harder to occur in this structure than the structure in which the front end of the pressure contact terminal fitting 20 receives pressing force.

Abstract: PURPOSE: To enable the sensitivity calibration of a neutron measuring radiation detector to be performed simply and surely by providing a mixture layer comprising mixing a slight amount of radioactive isotope into solid state fissionable material in a case and opposing the detecting part to the mixture layer.  
     CONSTITUTION: A mixture layer 1 comprising mixing a slight amount of radioactive isotope, e.g.,  241 Am to solid state fissionable material, e.g,  235 U and a semiconductor detecting part 2 opposing thereto are sealed in a case 3 connected to a power source 4.

On the other hand, in the place where no neutrons exist, the output pulses are generated by α rays such as 4.39MeV, etc. at which  235 U releases. When the count rate is low, the output pulses are generated by α rays of about 5.5MeV at which readily separated  241 Am releases. These output pulses are counted via preamplifier 5 and amplifier 6.
