Title: Manufacture of glass-lined material having high corrosion resistance
Inventor: HIJIKATA TOSHIO
IPC: C23D5/00
Filed: 1979-06-22
Abstract: PURPOSE: To manufacture glass-lined material having very high corrosion resistance, by heating a frit coating layer from metal side of the material toward surface layer side.  
     CONSTITUTION: Muddy frit is applied to the inner and outer peripheral surface of a long sized pipe, and is preheated by a high frequency induction heating means to a temp. not higher than the melting temp. of the frit, and is then quickly heated to a temp. not lower than the melting temp. in order to calcine it. Hereby the frit layer is heated from the material side toward surface layer, so that the formation of pinholes and bubbles is prevented. For example, a frit coating layer 2 is formed on the inner and outer peripheral surfaces of the material metal 1. A pipe 3 is hung under a high frequency induction coil 4, having such an inner diameter that its inner surface makes a prescribed space with the outer surface of the pipe 3, and in such a position that the axial line of the heating coil 4 agrees with that of the pipe 3. An electric power supply E is put to work, and the pipe 3 is pulled up in the direction of (a) at a prescribed speed and is preheated by the coil 4a and is heated regularly by a coil 4b. Hereby generated water vapor and gas are released easily to the outside of the coating layer, hence lining layer of uniform quality is formed.

Filed: 1984-04-18
Abstract: PURPOSE:To perform reliable detection through simple circuit constitution by blocking the part where two pressure conduit parts formed in a vortex generating body communicate with each other by a semiconductor pressure sensor, and detecting a pressure ripple. CONSTITUTION:When a piezo-resistance element 10 which varies in electric resistance when a semiconductor of silicon is strained mechanically is arranged at the communication part between the pressure conduits 5 and 6, the element 10 varies in resistance value with the pressure difference between the conduits 5 and 6. In this case, the pressure difference pulsates at a frequency based upon vortex generation and is inverted in polarity alternately.

Title: Distribution type fuel injection pump
Inventor: KAWASHIMA JIYUNICHI
IPC: F02M41/12
Filed: 1983-05-04
Abstract: PURPOSE:To prevent reverse flow of gas in a combustion chamber into a part discharged by a delivery valve upon finishing injection by increasing the effective opening area of a cut-off port gradually. CONSTITUTION:When a plunger 1 moves to the right in forced delivery stroke, the tip end of a knoched recess 21 is exposed from the right end surface of a control sleeve 10 at first upon the beginning of oil sending. Then, the amount of exposure is increased gradually and the whole of the cut-off port is opened to relief a pressure in a pressure chamber, thus, the oil sending is finished and injection is finished. According to this method, the effective opening area of the cut-off port 11 is increased gradually, therefore, the pressure in the pressure chamber will never become lower than the pressure in a cylinder under a condition that an injection valve is lifted and opened. Accordingly, there is no fear that a high pressure gas in the combustion chamber flows reversely into the injection valve and an injection pipe.
