Title: Method for controlling supplying quantity of molten metal and instrument for detecting molten metal surface level
Inventor: NODA SABURO
IPC: B29C45/76
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To precisely detect molten metal surface level and to improve the responsiveness of the detection by detecting that the molten metal reaches the reference level, with an electric short circuit between an electrode body and an injection sleeve and stopping the supply of the molten metal after passing a prescribed time. SOLUTION: In a control for supplying the molten metal, the molten metal in a furnace at a fixed molten metal surface is supplied into an injection sleeve 13 through a nozzle 21 and a timer 36 is worked. When the molten metal surface level risen in the injection sleeve 13 reaches the reference level L1 and contacts with the electrode 41, the short circuit is electrically generated between the electrode 41 and the injection sleeve 13. A detected signal with this short circuit is given to a CPU 38. The CPU 38 measures the time from the level L0 to the level L1 with a timer 36, and this time is stored in a memory. After passing the prescribed time since the reach of molten metal to the reference level L1 is detected with a detecting sensor 40, the driving of the molten metal supplying device 23 is stopped through the CPU 38.  Thereafter, a plunger tip is elevated and the molten metal supplied in the injection sleeve 13 is injected into a cavity in a metallic mold.

Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To provide the electrophoretic display device having improved reflectivity and contrast ratio, in which the difference between specific gravities of migration particles and a dispersion medium is reduced by lowering the specific gravity of the migration particle. SOLUTION: In the electrophoretic display device 10, a dispersion medium 13 colored by pigments and electrophoretic particles 14 dispersed in the medium 13 are enclosed in a gap between a transparent substrate 11 and an opposed substrate 12 which faces with the substrate 11.

Abstract: PURPOSE:To joint three crooked glass tubes at the same time to improve working performance so that generation of distortion and cracking can be reduced by performing a spraying-breaking process for two crooked glass tubes and a central crooked glass tube while the former ones are disposed distant from the latter one, and by moving the central glass tube and fusing them into a triangular shape. CONSTITUTION:U-tubes 1a and 1b are supported on the position corresponding to two sides of a triangle by means of chucks 11 and 12, respectively. A U-tube 1c is supported by a chuck 13 which is disposed from the chucks 11 and 12. Burners 25a to 25d disposed facing the fusion aimed parts of the glass tubes 1a to 1c are ignited to heat and soften the fusion aimed parts at the same time, and next the gas flame is put out once and air is supplied into the glass tubes 1a to 1c so that the fusion aimed parts are expanded. While the expanded parts are heated again, they are supplied with the air and broken by spraying. Air cylinders 33 and 34 are actuated to move the burners 25a to 25d backwards, and the glass tube 1c is moved forwards by means of an air cylinder 23 so that the spraying broken parts are touched each other. Burners 40 to 42 for a fusing operation are lowered by means of an air cylinder 47 and so the spraying broken parts are fused.

Filed: 1985-10-09
Abstract: PURPOSE:To make a solenoid valve to be compact, by making a fixed iron core adsorb a movable iron core, in case of being held a valve member at a position where this valve member opens/closes a valve seat by a spring energizing force, when the differential pressure between the input port side hydraulic pressure and the output port side hydraulic pressure, which act to the movable iron core, becomes lower. CONSTITUTION:A valve seat 9 is formed at the movable iron core 5-side end of an input flow route 7 of a fixed iron core 4, and a valve member 10 is set on the movable iron core 5. A spring 6 is so set as the movable iron core 5 opens the valve, through being pushed by the primary side hydraulic pressure, which acts to the movable iron core 5 in the valve seat 9, when the pressure of the primary side fluid which is fed from the input port through the valve seat 9, is sufficiently higher than the pressure of the secondary side fluid, but the movable iron core 5 closes the valve, when the difference between the fluid pressure of the primary side and that of the secondary side, becomes small. Accordingly, the adsorptive force between the fixed iron core and the movable iron core can be made small, and consequently, the solenoid operated part can be miniaturized.

Prior to the playing, the playing time of each music from the first music to the music which exceeds 46/2 (23) minutes is added, the specific frame of the music, that exceeds 23 minutes, is memorized.  Then, the playing is started and the playing is stopped when the specific frame of the music comes and the playing is interrupted. A timer computes the playing time till the interruption and the interrupted time and if the total time becomes equal to 23 minutes + α, the music playing is started again from the specific frame and the recording continues.
