Title: Noise mute circuit
Inventor: ISHII SATORU
IPC: H03G3/34
Filed: 1985-11-20
Abstract: PURPOSE:To simplify the circuit constitution and to reduce remarkably number of components by comparing a voltage of a signal line with a reference voltage set slightly larger than a peak of noise when no signal exists on the signal line. CONSTITUTION:At first the reference voltage V1 is set to a value slightly larger than the peak of noise on a system applied to an input terminal 1. When the input is only the noise to the system, an output of a comparator 3 is a positive voltage, a diode D1 is turned off and a base current ib is fed to a transistor (TR) Q1 from a position power supply 5 through a resistor R3 and the TR Q1 is turned on, then the muting is applied. When a signal is inputted, the output of the comparator 3 is a negative voltage while the signal voltage exceeds the reference voltage V1. The diode D1 is turned on in this case to draw an electric charge charged in a capacitor C1. Since a time constant C1.R2 is set smaller, the capacitor C1 is discharged at a high speed to release the muting.

Title: Polyurethane adhesive
Inventor: UEDA RYUICHI
IPC: C08G18/63
Filed: 1987-10-15
Abstract: PURPOSE:To obtain an adhesive which reveals excellent adhesive power even in bonding, e.g., PVC to Noryl, by grafting an acrylic monomer onto a thermoplastic polyester urethane rubber, and mixing the obtained graft polymer with a specified oligomer or polymer and an isocyanate compound. CONSTITUTION:This polyurethane adhesive consists of a component (A) prepared by grafting a thermoplastic polyester urethane rubber with at least one of (meth)acrylic acid and (meth)acrylic esters; an acrylic oligomer or polymer (B) that has a number-average molecular weight of 500-100,000 and has at the end or in the side chain functional groups containing active hydrogen atoms; and an isocyanate compound (C) as a crosslinking agent. Adhesives made by incorporating the component C into a principal component comprising a mixture of the component A with a chlorinated rubber have been known; however, they can hardly give sufficient bond strength in bonding PVC to an adherend of relatively low polarity, such as Noryl. The use of the component B in place of a chlorinated rubber in these adhesives can provide an excellent adhesion in such a case.
