Abstract: PURPOSE:To airtightly caulk and stick a thick plate and a thin plate by superposing a thick metallic plate and a thin metallic plate, and projecting and deforming two pieces of plates in a circular hole toward the thin plate from the thick plate by a male die having a circular projecting part and a female die having a circular hole. CONSTITUTION:A thick metallic plate 1 and a thin metallic plate 2 are superposed, the thin plate 2 is placed on a female die 3, a male die 4 is allowed to descend in the direction as indicated with an arrow, and by a circular projecting part 5 of the male die 4, two pieces of plates 1, 2 are projected and deformed in a circular hole 6 of the female die 3 to the extent that the thin plate 2 is not broken. Subsequently, the female die 3 is allowed to descend a little in the direction as indicated with an arrow, and in a state that the male die 4 remains placed against the side of the thick plate 1, only a male die 7 of a piston type is allowed to ascend in the direction as indicated with an arrow, in the female die 3. In such a way, two pieces of plates 1, 2 are compressed and caulked. Thereafter, when the male die 4 and the female die 3 are separated, both the plates 1, 2 become a state that they have been caulked and stuck firmly. By executing this caulking to several parts, both the plates are stuck firmly.

IPC: C22B9/00
Filed: 1987-01-14
Abstract: PURPOSE:To prevent foaming of the liquid surface of a molten metal and to produce a high-purity metal by constructing the upper part of a rotary cooling body to be immersed into the molten metal as a lower guiding part for the molten metal having a downward divergent shape and heating the outside peripheral face of said guide part. CONSTITUTION:Molten Al (A) contg. eutectic impurities is charged into a crucible 1 and the rotary cooling body 3 is immersed into the molten Al(A). The rotary cooling body 3 consists of the lower guide part 7 for the molten metal which diverges downward and a tapered part 3a which converges downward. The cooling body 3 is then rotated while cooling fluid is supplied thereon from a blow port 16 of a blow member 14 in the body 3. The outside peripheral face of the lower guide part 7 is simultaneously heated by energizing an electrical heater wire 19. The high-purity Al crystal I is thereby crystallized only on the tapered part 3a. The rising gaseous flow of the molten Al(A) is generated along the tapered part 3a at this time but descending flow is generated in an arrow X direction along the lower guide part 7 and therefore, the generation of vigorous waving on the liquid surface is prevented and the amt. of slat consisting of Al2O3 decreases.

Title: Engine starter of power vehicle
Inventor: IGUCHI HIROHIDE
IPC: B62D49/00
Filed: 1997-01-20
Abstract: PROBLEM TO BE SOLVED: To make an engine so as to be startable even if an operator leaves his seat by installing a switch to detect the forward tilting motion of a wheel post supporting a steering wheel, and another switch to detect the off-state of a clutch operating member after being connected to an engine starting circuit. SOLUTION: When an operator is seated, if he treads on a clutch pedal, and turns round a key switch 25, an engine starting circuit 26 operates and an engine gets starting, and if the operator leaves his seat, a seat switch 22 is reversed. In this case, only when the clutch pedal is treaded, and a clutch switch and a safely switch 24 are turned on, the engine will not work any longer, so a switch 27 should be turned to ON. In this case, however, the switch 27 is turned on when a steering wheel post 13 is tilted forward. In this state intact, if the key switch 25 is turned into operation, the engine is startable. In brief, if the operator leaves his seat, an engine start is performed, and thus its operability is well improved.

Abstract: PURPOSE:To detect an adhesive tape in a noncontact manner therewith irrespective of the reflectivity of said tape by a method wherein the absence or presence of said tape attached onto a sheet of paper is detected through the utilization of polarization of light. CONSTITUTION:Even when an adhesive tape 2 is transparent and, the reflectivity of incident light from a light source 3 is equal between the surfaces with and without the tape, the reflected light of the incident light is polarized depending on the uniform direction of the chemical treatment on the surface of the tape 2. Therefore, when the plane of polarization of the reflecting light is rotated by changing a voltage applied to a variable polariscope 5, the quantity of light incident on a light receiving sensor 4 differs according to the deflection angle of the polariscope 5 and a fixed polariscope 6. The pattern of the reflected light is different between the surfaces with and without the tape 2, whereby the presence or absence of the tape 2 can be detected.
