Title: Transistor power switch
Inventor: MIWA MAKOTO
IPC: H03K17/60
Filed: 1986-09-18
Abstract: PURPOSE:To contrive to improve the power efficiency by providing a transistor (TR) supplying a current flow its collector to a load, an emitter-base resistor, plural base resistors with different resistance, and a switch selecting the base resistors and changing the resistance between the base and ground according to the requirements of the load in response to the load current. CONSTITUTION:In throwing a switch 15 to the position of a base resistor 16, a current flows to resistors 14, 16, the base potential of the TR 13 is decreased and in the operating state. Then the supply voltage at the power terminal 11 is fed to a load terminal 12 via the collector of the TR 13 and the collector current is fed to a load 18. In this case, since the base resistor 16 is selected to have a large resistance, a small current corresponding thereto is supplied to a receiver. In throwing the switch 15 to the position of a base resistor 17, since the resistance of the base resistor 17 is selected to be small, a large current is given properly to a transmitter. Since plural base resistors between the base of the TR and ground are switched by the switch in this way, the base current is increased when a large current is called for in case of the transmission and the base current is decreased in case of the reception thereby improving the power efficiency.

Title: Pressure sensor
Inventor: TSUTSUI TOSHIHIRO
IPC: G01L1/10
Filed: 1996-08-21
Abstract: PROBLEM TO BE SOLVED: To measure a higher range of pressure of a gas surrounding a vibrator at a high accuracy with one pressure sensor by applying an AC voltage to a vibrator to vibrate for measuring a resonance frequency of the vibrator. SOLUTION: A pressure sensor 1 comprises a pressure sensor body 10 in which a resonance frequency varies according to changes in the pressure of a gas and a control circuit 40 to control the frequency of the pressure sensor body 10. The control circuit 40 contains an oscillation circuit for driving the pressure sensor body 10 and a measuring circuit to measure a pressure. The control circuit 40 makes a vibrator 20 vibrate at an oscillation frequency through a line 41. The resonance frequency at this moment is detected by an electrode 28 for pickup and fed back to the control circuit through the line 42. When a pressure intake port 17 is connected to a gas cylinder, the resonance frequency changes and the change is fed back to the control circuit 40 through the line 42. The control circuit 40 alters the oscillation frequency through the line 42 to math the resonance frequency.  The oscillation frequency when equaling the resonance frequency is monitored to detect the pressure.
