IPC: B29K105/04
Filed: 1988-06-14
Abstract: PURPOSE:To eliminate possibility such that a molded product is hooked with a release pin to generate trouble of double baking by a method wherein a mold is opened by allowing a moving mold to be spaced apart from a fixed mold and the release pin pushed out on the side of the fixed mold is once returned and and subsequently again pushed out to take out the molded product from the fixed mold. CONSTITUTION:After a molded product 4 is formed by heating and cooling, a moving mold 3 is allowed to be spaced apart from a fixed mold 2 to perfectly open a mold apparatus 1. At this time, a release pin 8 gradually applies pressing force to the molded product 4 remaining on the side of the fixed mold 2 in connection with the movement of the moving mold 3 accompanied by opening. Then, in order to once release said pressing force applied to the molded product to remove the hooking of the molded product 4 with the release pin 8 or to correct the posture of the molded product so that the vertical surface of said product is positioned on a perpendicular surface, the moving mold 3 is slightly moved toward the fixed mold 2 to once return the release pin 8 pushed out from the fixed mold. Subsequently, the moving mold 3 is again moved in the direction opposite to the fixed mold 2 and the molded product 4 is allowed to fall from the perfectly opened mold apparatus 1 by the pushing operation of the release pin 8 to be taken out of the mold apparatus 1.

Filed: 1981-09-18
Abstract: PURPOSE:To surely restore the circuit to lock state, by lowering an output voltage of a low pass filter with a control circuit when an unlock state of a PLL circuit reaches a set time and returning the voltage to a voltage within a lock operation possible range. CONSTITUTION:A phase detection circuit 2 compares an output of a reference frequency generating circuit 1 with a frequency or a phase of an output of a programmable divider 5, and an error signal based on the difference is generated. This error signal is converted into a DC signal at an LPF3 and this DC signal changes an oscillating frequency of a VCO4. When the PLL circuit is unlocked, a circuit 6 generating an unlock signal is connected to the phase detection circuit 2 and a circuit 7 detects the unlock time. If the unlock state is kept longer than the time set at an unlock time set circuit 8, an output voltage of the LPF3 is lowered through a control circuit 9 to control the circuit to the locking operation possible range.

Abstract: PURPOSE: To reduce the area of venturi during low speed for improvement of atomization and to increase the amount of mixed air for (the) improvement of output by making variable the negative pressure in a piston valve for a variable venturi type carburetter.  
     CONSTITUTION: A negative pressure chamber 3 is formed inside a piston valve 1 for a variable venturi type carburetter. The piston valve 1 moves vertically in proportion to the negative pressure of a venturi tube 9 transmitted from a negative pressure intake bore 1a. A needle valve 11 is vertically installed to a mixing chamber 10 facing the valve 1. The needle valve 11 is so arranged that its end may be inserted into the negative pressure intake bore 1a. With this construction, the transmission of negative pressure from the intake bore 1a is reduced during low speed, thereby moving the piston valve 1 downward while during high speed the negative pressure is transmitted as usual.
