Title: Microwave radiometer
Inventor: UENO MOTOHARU
IPC: G01J5/00
Filed: 1987-07-01
Abstract: PURPOSE:To improve resolution in a observing space and temperature resolution, by making at least one of the scanning speed of an electronic scanning antenna and the integration time constant of an integrator variable with a control part. CONSTITUTION:A microwave, which is received with an array antenna 2 through a reflecting mirror 1, is received with a receiving part 3 and amplified. Then an average value is computed in an integrator 4. Handling to temperature is performed based on the output signal value in a signal processing part 6 by using a chart and the like. The result is processed as the temperature data on the ground. Meanwhile, a control part 5 controls the scanning of the antenna beam of the antenna 2 by using scanning angles, scanning angle speeds and the data of the integration time constant, which are stored in a memory 20. The integration time constant of an integrator 4 is also controlled. Thus, the scanning speed is low at a part, where the scanning angle is small; and the scanning speed is high at a part, where the scanning angle is large. Therefore, the antenna 2 can be scanned so that the antenna beams are not overlapped.

Abstract: PURPOSE: To effectively cool a rotor by supplying cooling air from at least one hollow chamber between rotor disks into an axial passage, in a gas turbine which is provided with a bladed rotor and wherein the hollow chamber is present between the rotor disks and the axial passages are present on an outer peripheral part of the rotor. CONSTITUTION: A hollow chamber 9 is formed between disks 7, 8.

Cooling air is supplied from a center passage 20 into the axial passage 17ND of the outer peripheral part of a rotor penetrating the hollow chamber 9 and a connecting opening 18. As cooling air is bled from a center part of a compressor, air is effectively cooled with a low temperature and low pressure. As the hollow chamber 9 is narrowed exceeding a ring chamber 11, contamination in cooling air is ejected from the connecting opening 18, and the contamination is prevented from sticking.

IPC: F02P11/06
Filed: 1980-11-18
Abstract: PURPOSE: To enable detecting a normal operation of an ignition plug and a sure ignition of a burning gas.  
     CONSTITUTION: Instead of an extermely high secondary voltage of an ignition coil 2, a relatively low primary voltage is detected and after a capacity 11 is charged with the voltage, the capacity 11 is discharged at a certain time constant, thereby producing a charging or discharging waveform voltage. By comparing the voltage with a constant reference voltage, a pulse signal can be obtained. An actuation of the ignition plug 5 may be detected by confirming a presence or an absence of the output of the pulse signal. Another pulse signal is obtained by comparing the charging or discharging waveform voltage which is provided by dividing the primary voltage of the ignition coil 2 with the constant reference voltage vth. If the pulse signal is shaped to have an approximately equal pulse length, a CPU1 may easily process the signal.

IPC: F28B1/00
Filed: 1981-10-14
Abstract: PURPOSE:To prevent the water chamber of the condenser from being subjected to an excessively heavy load due to an earthquake or the like by a method wherein in the  steam turbine condenser provided with flexible joints between the trunk and the water chamber thereof, the water chamber is made movable in the longitudinal direction of  a cooling pipe but is restrained to move in the direction normal to the cooling pipe. CONSTITUTION:The five quakeproof means 10 are attached to the trunk 1 of the condenser at positions adjacent the water chamber 4' with one end of each of the quake- proof means 10 held across each of the flexible joints 5. The quakeproof means 10 are so formed that they can move in the longitudinal direction of the cooling pipe 2 but  are restrained to move normal to the cooling pipe 2. With the above structure, when  the movable side of the water chamber 4' is subjected to the force of inertia in the  direction normal to the cooling pipe 2, the counter-force is born upon by the quakeproof means 10 so that no excessive load is applied on the flexible joints 5, a pipe  plate 3 and the cooling pipe 2 and the expansion and contraction of each of the flexible joints 5 due to the difference in expansion resulting from the variation of temperature during the operation of the condenser are not obstructed. Accordingly, it is possible to prevent the flexible joints 5, the pipe plate 3 and the cooling pipe 2 from being  damaged.

IPC: F16D7/02
Filed: 1986-07-10
Abstract: PURPOSE:To aim at improvement in durability in reducing a sliding speed by half at both inner and outer taper surface parts when a catching phenomenon occurs, by installing a taper cylindrical collar side by side between taper surfaces pressing a reduction gear with each other free of slide motion. CONSTITUTION:With starter motor operation, to be decelerated from a pinion gear and transmitted to a first gear 20 is decelerated and transmitted to a shaft 19 from the first gear 20 within the torque capacity range of a torque limiter 23 and furthermore to a crankshaft via a second gear 18. And, immediately after engine starting, a catching phenomenon, where the crankshaft is reversed, is caused and thereby excessive load is imposed on these gears 18, 20 or the like, but the turning torque of the first gear 20 becomes larger than capacity of the torque limiter 23, so that the first gear 20 slips to the shaft 19 whereby excessive torque is prevented from occurring. At this time, an interval between taper surfaces, where a flange 26 of the shaft 19 and the first gear 20 both come into contact with pressure, is relatively slidden with each other via a taper cylindrical collar 30, thus a sliding speed to this collar 30 is reduced by almost half. Doing like this, durability in a starter is improved.
