Title: Vibrating type transducer
Inventor: NAKAGAWA WATARU
IPC: G01L9/00
Filed: 1987-03-30
Abstract: PURPOSE:To reduce the quantity of the thermal deformation of a mechanism vibrator and to reduce a temperature error by arranging plural driving elements at a vibration driving part. CONSTITUTION:A diaphragm driving part 20 is provided so as to make a vibrator bottom part 1a perform bending vibration, and the six driving elements 21 are arranged in a link shape at the driving part 20 on the internal surface of the bottom part 1a concentrically about the center of the bottom surface. A connection line 22 connects electrodes 21b and 21b of adjacent elements 21 and five electrodes 21b are connected at the driving part 20 by the connection line 22 so that they are at the same potential. Consequently, even if there is a difference in coefficient of thermal expansion between a diaphragm and the elements 21 which constitute the driving part 20, thermal deforming force to the mechanical vibrator 23 due to the difference in coefficient of expansion and the temperature variation of measurement fluid is small as compared with when the driving part 20 is formed of one element 21. Therefore, the thermal deformation quantity of the vibrator 23 is reduced and the temperature error is reduced.

Title: Sun tracking device for heat collector
Inventor: NAKAO MASAKI
IPC: F24S50/20
Filed: 1980-06-09
Abstract: PURPOSE: To eliminate the supply of working energy from the external by providing a direct sunlight shield vertically on a heat collecting surface of the heat collector and arranging a pressure vessel on both sides of the shield so that the heat collector is operated in accordance with a difference in the pressure of satuated gas within the pressure vessels.  
     CONSTITUTION: When the sun is in a position, for example, (a) in the drawing, in the pressure vessel 13 receiving the direct sunlight the temperature rises, whereas in the other pressure vessel 14 shielded from the direct sunlight by the shield 12 the temperature is lower than that in the pressure vessel 13. Accordingly, the pressure of the satuated gas in the pressure vessel 13 is higher than that in the pressure vessel 14, so that in a cylinder 7, the pressure on the piston head side is higher than that on the piston rod 9 side. By this, a piston 8 is pushed outwardly and the heat collector 1 is rotated around a pin 4 through the piston rod 9, so that the heat collecting surface 2 is oriented toward the sun. Accordingly, the sun tracking movement can be obtained without supplying any external energy such as electric power.

Title: Input/output circuit
Inventor: KAMIYA YASUJI
IPC: H03K19/0175
Filed: 1989-03-28
Abstract: PURPOSE:To reduce a delay time of an output signal caused by an output circuit by using a transfer gate provided on the way of an output signal line so as to switch the impedance of the output signal line at the impedance between a high impedance and a low impedance in response to an input output control signal. CONSTITUTION:When the title circuit is used as an output circuit, a transfer gate 1 is opened by using an input and output control signal outputted to a control signal line G. Thus, an output signal of an internal logic cell part outputted to an output signal line 5 is subject to waveform shaping by inverter circuits 10, 11 of an output circuit part and outputted to the outside of a chip via a signal pad 3. On the other hand, when the title circuit is used as an input circuit, the transfer gate 1 is closed by the input output control signal outputted to the control signal line 6. Thus, the output signal line 50 reaches a high impedance state and it is equivalent that the output signal line 5 is not electrically connected. Thus, the delay time is adjusted for each output terminal.

Abstract: PURPOSE:To eliminate the need for a separate call detecting part at the time of power failure and to decrease the number of parts by connecting an energizing time speech path and a power failure time speech path through a common detecting part detecting a calling current at the time of the energizing to a line wire, and controlling a call holding action after the restoration of the power failure based on the output signal of the detecting part. CONSTITUTION:At the time of the power failure, a call signal from a line wire 3 is inputted through a terminal 111 to a detecting part 113, outputted to a terminal 112, and further, inputted through a cable 4 to a terminal 123. When the power failure is restored, a CPU 116 immediately inputs the detected output of the detecting part 113, and when the call condition is detected based on it, the information is sent through a data line 15 to a central CPU 14. The CPU 14 collates the information with a trunk line used at the time of the power failure set beforehand and the table of an extension, and judges which the busy extension connected to the trunk line is. Further, the CPU 14 sends an instruction to prevent the action of a relay 124 to a CPU 130 of an extension interface 12 concerned. Thus, the call established beforehand during the power failure is held.

Abstract: PURPOSE:To reduce the current consumption in a no-load mode by detecting and feeding back the output voltage via a control circuit consisting of resistances and transistors and controlling the current supply value of a line in accordance with the output voltage. CONSTITUTION:A resistance R1 and a pnp transistor (TR)Q1 are connected in parallel between terminals 9 and 1. The collector of an npn TRQ2 is con nected to the base of the TRQ1 and the collector of a pnp TRQ3 whose emitter is connected to the terminal 1 through a resistance R2 is connected to the base of the TRQ2. Then a capacity C1 is connected between the emitter of the TRQ3 and a terminal 2. In case the DC voltage produced between terminals 1 and 2, i.e., the output voltage Vreg is increased, the base current of the TRQ1 is reduced and therefore the voltage Vreg is also reduced. While the base current of the TRQ1 increases when the voltage Vreg decreases and therefore the Vreg increases. In such a circuit operation, the voltage Vreg is kept at a fixed level.
