Title: Crystal resonator piece
Inventor: YAGI SHINICHIRO
IPC: H03H9/19
Filed: 1989-03-31
Abstract: PURPOSE:To permit the confining function of vibrating energy to be fully displayed even if a small-sized crystal board is used by sequentially and continuously enlarging the thickness of electrode films in plural stages from the outer peripheral parts or the end parts of the electrode films formed on the main surface of the crystal board to a center part. CONSTITUTION:A crystal resonator piece 1 is constituted in such a way that the electrode films 6a-6e whose sizes of diameters sequentially become small are piled up and vapor-deposited on the main surfaces 5c and 5d of the rectangular crystal board 5 so that they become concentric circle or that the electrode films 6a-6f in which the lengths in a horizontal direction sequentially become small are piled up and vapor- deposited on the main surfaces 5c and 5d of the rectangular crystal board 5. Thus, the difference of the stages in the end parts of respective electrodes films occurs in vibration displacement with such constitution, and the occurrence of the considerably large discontinuous difference of stages at every part is prevented. The distribution of vibration displacement has plural small differences of the stages by they come almost continuous when they are totally viewed. Then, the confining effect of vibrating energy which is larger than a conventional one can be obtained without affecting an adverse influence on various characteristics of the crystal resonator by mass-loading.

Title: Power amplifier circuit
Inventor: TOZAWA YOJI
IPC: H03G3/30
Filed: 1990-03-30
Abstract: PURPOSE:To prevent an excess output by providing an output suppressing means which reduces the gain of a power amplifier at the time of output of an ALC signal from an excess output detecting circuit. CONSTITUTION:When the output from a power amplifier 14 is excessive, the ALC signal is outputted by an excessive output detecting circuit 16. This ALC signal has a prescribed voltage value EALC. A fixed voltage Eg is outputted from a constant voltage source 20, and a difference voltage EGS=Eg-EALC is outputted from an adder 22 to the power amplifier 14 while the ALC signal is outputted. Since the output of the adder 22 is supplied as the gate bias voltage of a power MOSFET, the gain of the power amplifier 14 is reduced when the ALC signal EALC is outputted from the excessive output detecting circuit 16. Thus, an interface condition is insignificant and the fault due to the excessive output is eliminated.

Abstract: PURPOSE:To enable delicate gradation recording by installing a mist catcher with an opening or a notch section larger than an orifice hole to the front of an orifice. CONSTITUTION:A mist catcher 2 with an opening 3 is mounted to the front of a head 1. The opening 3 is made larger than the orifice diameter of the head 1, and has size through which an ink drip can pass.

Title: Overheat prevention unit for internal combustion engine
Inventor: NASUDA YUTAKA
IPC: F02P11/04
Filed: 1980-06-20
Abstract: PURPOSE:To prevent the damage of engine by detecting the temperatures of an internal combustion engine and by halting the operation of an ignition circuit during overheating. CONSTITUTION:A thermal detector 30 is designed to operate when the engine is overheated. As a minute current flows into a transistor 98 through a main switch 90 and a buzzer 92 in normal operation, the transistor 98 is on, and a thyristor 96 remains to be off. Therefore, the ignition circuit operates. As the base current for the transistor 98 flows into an earth through the switch 30 for the thermal detector during overheating, the transistor 98 is turned off. As the thyristor 96 is turned on by the current flowing through resistors 100 and 102, an generating coil 60 is shorted. Therefore, the ignition circuit stops operating. With this construction, the ignition circuit stops operating during overheating, which can prevent the damage of engine. The overheating conditions can be also detected from the buzzer 92.
