Filed: 1978-07-11
Abstract: PURPOSE:To enable to detect the feeding groove between records and the introducing groove without malfunction, by constituting that the detector for tone arm mobile speed is inoperative when the tone arm goes upward. CONSTITUTION:The collector of transistor TR is connected to the output terminal b of the differentiating circuit, the emitter is grounded, and a DC voltage is applied to the base via the contact 12-1 of the switch 12 of the lifter 7. With this constitution, when the tone arm 1 is manually moved from the external circumference to the inner circumference of the record disc, the voltage produced at the point a is inputted to the differentiating circuit consisting of the capacitor C1 and the resistor R1 via the amplifier A1, but the voltage at the output terminal (b) is zero volt. Accordingly, only when the feeding groove between records and the introducing groove are met, the voltage is produced at the point (b) and the output voltage is obtained at the output terminal (d), allowing to detect the feeding groove between records and the introducing groove without malfunction.

Abstract: PROBLEM TO BE SOLVED: To improve the heat resistance of the surface of a vaporizer and to prevent Zn from being deposited by applying a heat-resistance paint to the surface of the vaporizer or a partial surface being located in combustion flame. SOLUTION: A vaporizer 9 is partially located in combustion flame 18 of a burner 2 as a heat reception part 17 to eliminate the conduction of a heater 11 for a vaporizer during combustion, the heat energy of the combustion flame is collected, and the temperature of the vaporizer 9 is increased due to thermal conduction. The vaporizer 9 is made of brass considering heat conduction or the like but reaches an extremely high temperature due to abnormal combustion where air becomes excessive, and Zn content is deposited and released at 550 deg.C or higher.
