Title: Molding method for resin product
Inventor: YAMAMOTO KEIZO
IPC: B29C33/02
Filed: 1989-11-30
Abstract: PURPOSE:To correct automatically warping of a resin product and reduce warping by utilizing the difference of heat shrinkage volume following the cooling of respective sections in contact with respective frames of a resin product and reducing warping of the resin product. CONSTITUTION:Materials of a resin product, that is a thermoplastic material, a thermosetting material and the like, are provided, which are injected into a mold 1 to mold a resin product S. Then a high temperature side section S1 in contact with a frame 2 on the high temperature side constituting the mold 1 and warping in the projecting direction of a low temperature side section S2 in contact with a frame 3 on the low temperature side and warping in the recessed shape are generated on the resin product S after molding. lf thus manufactured resin product S is left, for instance, in the atmosphere and cooled, larger heat shrinkage is generated on the high temperature side S1 according to the temperature difference between the high temperature side section S1 and the low temperature side S2. As a result, correction is carried out automatically for equalizing the lengths of both sections S1 and S2 because of the difference of heat shrinkage amount of both of the sections S1 and S2 to reduce warping of the resin product S.

IPC: H04N9/87
Filed: 1989-11-30
Abstract: PURPOSE:To bring the coring characteristic close to an ideal characteristic by using a voltage follower as an amplitude limit means limiting one side input of a differential amplifier. CONSTITUTION:A coring circuit is a circuit limiting a base input amplitude of a transistor(TR) 1 comprising the connection of 1st and 2nd voltage follower circuits. A signal shown in waveform diagram (a) is inputted to a base of a TR 2. On the other hand, a base input waveform of the TR 1 is as shown in figure (b). That is, the 1st voltage follower is conductive at a high level of the input signal to limit the input signal to a voltage (V1+V2+V3) and the 2nd voltage follower is conductive at a low level of the input signal to limit the input signal to a voltage V1. Finally, the waveform is as shown in figure (b) and since the switching characteristic of the conductive/nonconductive voltage follower is excellent, a steeper clip waveform than a conventional waveform is obtained. Thus, the base voltage difference of the TRs 1,2 is close to an ideal waveform as shown in figure (c).

Filed: 1986-12-26
Abstract: PURPOSE:To shorten leading time at the application of power by providing a Zener diode connected in forward direction toward the positive power supply polarity from the high potential side of a smoothing capacitor constituting a DC feedback circuit. CONSTITUTION:The Zener diode 3 connected in the forward direction toward the positive polarity side of the smoothing capacitor C1 constituting the DC feedback circuit 2 form its high potential point. The voltage Va of the positive power supply connected to the capacitor C1 via the Zener diode 3 is selected in the relation of +Va<Vz+Vf, where Vz is the breakdown voltage of the Zener diode 3 and Vf is the voltage of the smoothing capacitor constituting the DC feedback circuit 2 during normal operation. Since a voltage (Va-Vz) is applied directly to the smoothing capacitor C1 as soon as the power supply is applied, the smoothing capacitor C1 is charged rapidly till the breakdown voltage Vz of the Zener diode and charged by a feedback signal only while the Zener diode 3 is cut off and its voltage reaches the voltage Vf. Thus, the leading time is shortened remarkably.
