Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a fire monitoring optical fiber cable having high heat resistance and high detection accuracy by preparing a metallic pipe and a coated fiber formed by a quartz core, a quartz clad and polyimide covering the core and the clad and inserting the coated fiber into the pipe. SOLUTION: The fire monitoring optical fiber cable 10 is constituted of an optical fiber 11 and a metallic pipe 12. The coated fiber 11 is formed by a quartz core 111 of which outer diameter is about 200 μm, a quartz clad 112 having about 250 μm outer diameter and formed on the outer periphery of the core 111 and a coating 113. The coating 113 having about 0.28 mm outer diameter and covering the core 111 and the clad 112 is formed by polyimide. Since the coating 113 is formed by polymide, the coated fiber 11 has heat resistance as compared with the use of a conventional material such as Teflon and temperature measurement up to a high temperature range >= about 300 deg.C can be attained.

Next, it enters in the turbine 2 and operates there. On the occasion, the suction air for the compressor 3 is cooled beforehand by the air cooler 4 utilizing the heat cooling property of the liquefied natural gas supplied to the burner 6, while, in addition, dehumidification is performed by a dehumidifier 5 before the above precooling. Moreover, by the dehumidification by the dehumidifier 5, freezing and frosting in the air cooler 4 are reduced, which raises the cooling effect of the cooler 4.

Title: Level alarm detecting circuit
Inventor: MIYAMOTO HIDETO
IPC: H04M3/10
Filed: 1979-08-15
Abstract: PURPOSE:To make it possible to set an alarm level and a hysteresis width independently of each other, by changing the bias of the diode according to change of the output voltage of the comparator. CONSTITUTION:For the standard input voltage, alarm level adjusting variable resistor RV1 is adjusted to make the output voltage of zero potential. At this time, if reference voltage E1 is within the fluctuation width of the output voltage of comparator IC, diode RC becomes the forward bias, and the potential at point A becomes equal to E1. Consequently, an alarm level can be set independently of hysteresis width adjusting variable resistor RV2. Next, when the input is reduced to make the output equal to power source voltage E, diode RC becomes the backward bias. Then, the potential at point A is fluctuated from E1 to the + direction by adjusting RV2. That is, the reference voltage applied to IC becomes higher than that for alarm level set, and hysteresis is given at a release level decision time.

Furthermore, it is possible for the chip 1 to be removably mounted in stable condition to the top of the handle 4. It is also possible that the leg 5 is cut at its top and separated into left and right leg parts.

Title: Pressure-mechanism convertor
Inventor: TANIO SHIGEHARU
IPC: F01B7/00
Filed: 1986-05-09
Abstract: PURPOSE:To simplify the construction of a fluid guide means and reduce the number of valves by mounting a change-over means by which pressure of working fluid acts alternatively on the primary and secondary pistons connected to a common output mechanism. CONSTITUTION:Primary and secondary pistons 21 and 22 are slidably placed in series with each other inside a cylinder 20. A slide rod 23 and the secondary piston 22 are connected to a crank 26 each other via primary and secondary connecting members 27 and 28. Fluid guide means 31-33 make working fluid pass through the cylinder 20.

Abstract: PURPOSE:To improve warming performance of an exhaust system without deteriorating the idle operation property at engine cooling by connecting a fluid pressure operating chamber to a suction delivery port when the rate of warming is less than a prescribed value and also in an idle operation, and otherwise connecting it to the atmosphere. CONSTITUTION:When the cooling water temperature of an internal-combustion engine is lower than a prescribed value, a solenoid valve 27 is turned on at idle operation, and a diaphragm chamber 23 is connected to a suction pipe negative pressure delivery port 29, allowing a valve element 17 to be fully closed. In other operating state except the case described above, power supply to the solenoid valve 27 is stopped, and the atmospheric pressure is fed into the diaphragm chamber 23, allowing the valve element 17 to be fully opened. With the engine cooling water temperature over the prescribed value, the solenoid valve 27 is always turned on, allowing the pressure appearing at the negative pressure delivery port 29 in the suction pipe to be introduced into the diaphragm chamber 23. At the idle operation and a low load operation, negative pressure over the prescribed value is fed into the diaphragm chamber 23.

Title: Reference voltage source circuit
Inventor: KUMANO MASAHIRO
IPC: G05F3/30
Filed: 1985-05-17
Abstract: PURPOSE:To improve the setting accuracy of the reference voltage when a reference voltage source circuit is converted into an IC, by making use of the difference of voltage between the base and the emitter of the transistors of the same type to convert the reference voltage obtained by dividing the power supply voltage by a resistance ratio into power supply of a low impedance. CONSTITUTION:The npn diodes 20 and 21 whose collectors and bases are connected to each other are connected in series between the emitter of a pnp transistor (TR) 6 and the collector of a pnp TR 7. For an IC, it is also easy to attain the accuracy of about + or -1mV as long as the current level is constant for the voltage difference VBE between the base and the emitters of the TR of the same type. Therefore the VBE of the TR 6 is equal to that of a diode 27 and furthermore the VBE of the diode 20 is equal to that of a TR 26 as long as the same resistance value is set between resistances 8 and 22 and between resistances 25 and 29 together with the same current value set among the TR 6, diodes 27, 20 and 21 and the TR 26 respectively. Thus the reference voltage of a reference voltage terminal is obtained from the difference of VBE between the npn transistors of the same type. This improves the setting accuracy of the reference voltage.

The amplifier section 11 outputs an information signal D2 where the flat loss of the signal D1 is equalized. The signal D2 is inputted/outputted to/from a sloped again amplifier section 31 and its output information signal D3 is inputted to a sloped gain control section 41. The control section 41 controls the gain of the amplifier section 31 so that the signal D3 has a prescribed amplified based on the signal D3 and converges the signal so that the slope loss is equalized properly.
