Title: Casting method
Inventor: GOIE MASATO
IPC: B22D19/00
Filed: 1983-07-19
Abstract: PURPOSE:To melt-stick thoroughly a pipe insert-cast into a casting in the stage of insert-casting of the pipe into the casting by holding the other of the cores inserted into both ends of the slightly shorter pipe into the core print parts between the parting planes of a cope and a drag. CONSTITUTION:Bar-shaped shell cores 8 are fitted at one end into both ends of a pipe 5 having the length shorter than the distance between the end faces 7 and 7 of a casting and are held on the other end as core prints 4 in the casting mold in the stage of insert-casting of the pipe into the casting. Since the pipes 5 does not arrive at the faces 7, 7, the outside surface of the pipe 5 is thoroughly embedded by the molten metal poured into the casting mold and is thus thoroughly melt-stuck. The casting after knock-out is cleaned by shot blasting, etc. Since the cores 8 have a short length, easy sand stripping from the face 7 of the casting 7 is made possible and the removal and conditioning of the cores 8 are extremely easy as well. The end faces of the pipe 5 are not exposed and therefore there is no possibility of damaging a cutting tool, deteriorating dimensional accuracy, etc. in the case of machining the face 7.

IPC: B21B21/00
Filed: 1977-10-31
Abstract: PURPOSE: To obtain a heating tube of a raised overall coefficent of heat transfer by the procedure in which tunnel-shaped cavities are formed on the inner and outer walls of tube by forming dents and projections in mandrel or roll and then by rolling it with piriger -mill rolling in order to accelerate boiling phenomenon.  
     CONSTITUTION: The dents 10 and the projections 9 are formed in the axial direction of the mandrel 7 or in the diametral direction of the piriger roll 5, and then piriger -mill rolling is made to form grooves matching with the dents and the projections on the inner or outer wall of tube. Then, it is drawn to a fixed final diameter, whereupon the grooves formed suffer compressive stress in its diametral and thicker direction and also suffer tensile stress in its axial direction to deform, forming tunnel-shaped cavities connected in the axial direction of tube. The formation of the cavities enables boiling phenomenon in heating tube to take place very readily, thus giving excellent haet transmission effect.

Title: Injecotr for two cycle engine of portable type working device
Inventor: ROORANTO SHIIARINGU
IPC: F02B75/02
Filed: 1988-05-31
Abstract: PURPOSE: To eject an appropriate amount of fuel with a high ejecting pressure using the pressure in a crank-case sufficiently by generating a changeable resistant pressure in a return chamber of an injection pump driving chamber depending on an engine driving speed and a pump piston process. CONSTITUTION: A driving chamber of an injection pump is divided into an impacting chamber 21 and a return chamber 23 by a diaphragm 22. In the driving chamber, when a driving speed of two-stroke engines 2 is increased, a throttle 36 operats because a flowing velocity of a fuel which passes in a compensation duct 35 is increased. Thereby, a resistant pressure is generated in the return chamber 23 at every working process of a pump piston 25 car the diaphragm 22. The more the flowing velocity of fuel which passes the compensation duct 35 becomes fast, the more resistant pressure is increased because the stop 36 displays an effect and the resistance pressure affects on the diaphragm 22, then generates a force which react on an operating force in the impacting chamber 21.  Therefore, an amount of fuel injection can be decreased regarding to its driving speed so as to suit an amount of air which is inhaled in the engine 2 because the more the winding number increases, the more the process of piston become small.

Abstract: PURPOSE:To discriminate a frequency stably against the fluctuation of the frequency of the color subcarrier, by utilizing the fact that the level radio of two kinds of spectrum becomes infinite in the valley part of spectrums. CONSTITUTION:An input horizontal synchronizing signal fH including frequency variation DELTAf is multiplied in a PLL multiplying circuit 32 by an integral multiple to obtain a signal which is equal to one of two frequencies of the color subcarrier and is synchronized with the horizontal synchronizing signal, and the sum of this obtained signal and a reference frequency fS from an oscillator 36 is obtained by a frequency converter 34. The difference between the output signal from the converter 34 and the burst gated color subcarrier frequency from a terminal 40 is operated by a frequency converter 38, and frequency variation DELTAf is eliminated to obtain frequencies fS and fS+10fH. Next, a valley of the frequency spectrum of the frequency fS or fS+10fH is obtained, and its frequency is used as a center frequency for discrimination of an SECAM signal.
