Title: Connection circuit of test waveform generator
Inventor: YAMADA HIROKI
IPC: H04M3/26
Filed: 1984-02-24
Abstract: PURPOSE:To attain a surge characteristic test with a test waveform having large energy and also to apply the test waveform to a test circuit which no deterioration of the rise characteristic of an output waveform of a waveform generator, by connecting a varisterl and a capacitor in parallel to form a connection circuit. CONSTITUTION:The electrostatic capacity C1 of an equivalent circuit shown in a figure (a) is shown together with the input capacity C2 of a circuit to be tested. The ramp wave input fed from a generator A is assumed as Vin together with the action start voltage of a varister is assumed as Vz, respectively. Thus a test voltage waveform V(t) which is supplied to the circuit to be tested via an internal equivalent resistance R is kept at [Vin-V(t)]<=Vz until the varister of a connection circuit reaches the voltage Vz. Then V(t)=Vin-Vz is satisfied after the varister reaches Vz. In such a case, the rise characteristics producing a time delay are equal to the ramp wave input Vin as long as C1<<C2 is satisfied. However the varister serving as a connection circuit is delayed more to reach an active area as the C1 becomes larger than the C2. At the same time, the rise characteristics are improved. Therefore a high tolerance level is secured by a varister Z in a constitution of a figure (b). Then the waveform rise characteristics are improved with parallel connection of capacitors C.

Filed: 1981-03-13
Abstract: PURPOSE: To accumulate or release hat each at a predetermined temp. by use of a heat-accumulating material prepd. by incorporating naphthalene in sodium thiosulfate pentahydrate.  
     CONSTITUTION: Naphthalene is added to a main component consisting of sodium thiosulfate pentahydrate. As a nucleating agent for sodium thiosulfate, naphthalene has a remarkable effect in comparison with other materials, and calcium sulfate and an alkali metal halide such as sodium chloride, potassium chloride, potassium bromide or potassium iodide are effective as the nucleating agent. These materials have a nucleating power probably because naphthalene is capable of being present as a nucleus in water because of low water-solubility, and a crystal of sodium thiosulfate pentahydrate easily grows on naphthalene in view of interfacial surface energy because of the same crystal form of sodium thiosulfate and naphthalene.
