Abstract: PURPOSE:To control the tension of a tape to be normal even at the shifting of a tape running mode, by providing an initial value voltage generation unit which applies an initial value voltage to a phase compensation circuit when no tape tension detection signal is supplied to the phase compensation circuit. CONSTITUTION:The tape tension detection signal from an input terminal t1 is applied to a level comparator 25 through a changeover switch SW1 and a phase compensation circuit 21. The level comparator 25 produces an output which corresponds to the result of the comparison of the output of the phase compensation circuit 21 with a reference voltage from a tape tension setting reference voltage source 30 and which is applied to an output terminal t2 through a switch SW2. When the detection circuit is not working, the switches SW1, SW2 are open and another switch SW3 is closed. At that time, a voltage from an initial value voltage generation unit 35 is applied to the capacitor 24 of the phase compensation circuit 21 so that the output voltage of the circuit 21 is set at a prescribed value.

IPC: H04N1/407
Filed: 1982-06-30
Abstract: PURPOSE:To hold the reference level of an input modulated pulse signal constant and to stabilize an output signal by synthesizing an input pulse signal and its negative-phase pulse signal and holding the peak. CONSTITUTION:The input pulse modulated signal is supplied to a capacitor CH through the 1st operational amplifier OP1 and diodes D1 and D2 to be peak-held.

Title: Semiconductor pressure sensor
Inventor: TAKAKURA NOBUYUKI
IPC: G01L19/04
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To detect pressure accurately over a wide temperature range by suppressing the deformation of a diaphragm incident to temperature variation thereby reducing the offset of sensor output. SOLUTION: A silicon substrate 1 is arranged with a pressure receiving diaphragm 2a and piezoelectric resistors 4 for detecting the deformation of the diaphragm 2a is formed thereon. The silicon substrate 1 has one side covered with a protective film, i.e., a silicon oxide film 3, which is covered with a silicon nitride film 6. Since a stress produced in the diaphragm 2a is suppressed by the silicon nitride film 6 due to the difference of the coefficient of thermal expansion between the silicon substrate 1 and the silicon oxide film 3, the deformation of the diaphragm 2a incident to temperature variation can be suppressed.

Thus, a high frequency cancel sound s1 is outputted from the silencing speaker 1 to a silencing space B. Then only sound of high frequency components among external noise sounds (c) are silenced in the silencing space B through the cancel action by the cancel sound s1.
