Abstract: PURPOSE:To obtain a sound casting without being cooled suddenly in an injection process by providing a crucible so as to be freely tiltable around a horizontal axis in a casting chamber, maintaining it horizontally by a stopper at the time of melting, and inclining it by its dead weight by releasing the locking at the time of casting. CONSTITUTION:When a casting material is put into a crucible 2 and melted by a heating and melting means, and the crucible 2 is inclined around an axis center of a horizontal axis 3, a molten metal is injected into a cavity of a mold from a port edge 21 and casting is executed. At the time of melting, the crucible 2 is held in a horizontal state by a stopper 32 and a molten metal is stored in the crucible 2, and at the time of casting, the locking of the stopper 32 is released and the crucible 2 is inclined and rotated quickly by its dead weight, and the molten metal is poured from the port edge 21. In such a way, even if an unmelted portion exists to some extent in the crucible 2, it remains behind in a bottom part of the crucible 2, and only a molten metal melted completely is poured instantaneously into the mold. Accordingly, at the time of pouring, the molten metal permeates to every nook and corner in the cavity without being cooled suddenly, and a homogeneous and sound casting is obtained.

Abstract: PURPOSE: To obtain excellent antistatic properties, adhesive properties and coated film strength, by coating at least one face of a polyester film on whose surface layer the concentration of sulfonic acid or sulfonate salt is in a specific range, with a layer containing a polymer whose main constituting component is a specific repeating unit, and thereafter drawing it.  
     CONSTITUTION: It is necessary that the concentration of sulfonic acid or sulfonate salt is 0.002W2.0%. If the concentration is smaller than 0.002%, the coated film strength becomes poor and if the concentration is larger than 2%, the characteristics of base material polyester becomes worse. lt is necessary that 5wt.% or more and 95wt.% or less polymer whose main constituting component is a repeating unit represented by the formula (I) is contained in the coated layer. If the content is less than 5wt.%, the effect improving adhesive properties and antistatic properties becomes insufficient and if the content is more than 95wt.%, the coated film toughness becomes poor. It is especially preferable that balance between the adhesive properties, the coated film toughness and the antistatic properties is good when the content is 10wt.%W30wt.%. The thickness of the coated layer after drawing is usually 0.001W5μm.

Title: Balanced amplifier circuit
Inventor: MATSUMOTO YOSHITERU
IPC: H03F3/68
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce the effect onto the balance amplification factor of the balanced amplifier circuit due to an output impedance of a signal source by adopting a high input impedance for the amplifier circuit and to easily vary the balance amplification factor at a low cost. SOLUTION: The circuit configuration shown in figure indicates a balanced input balanced output amplifier whose balance amplification factor depends on a ratio of resistance values of resistors R1-R4. A balanced amplifier 7 amplifies only difference components of a balance input signal and provides an output of a positive phase output signal and an opposite phase output signal. Since the balance amplification factor of the entire balance amplifier circuit can be decided only by a resistance of the resistor R3, the balance amplification factor is made variable by varying the resistance of the resistor R3 only. Even when the resistance of resistors R1a , R1b is selected small and resistance of resistors R2a , R2b is selected large, a high input impedance is attained and then the effect of an output impedance of a signal source onto the amplification factor of the circuit is reduced.
