Title: Manifold pressure reduction device
Inventor: FUJINE YOSHINOBU
IPC: F16K17/18
Filed: 1979-11-30
Abstract: PURPOSE:To enhance accuracy of diaphragm by setting an arbitrary pilot pressure between a positive and negative pressure sources and obtaining thereby pressure reduction in both the positive and negative pressure. CONSTITUTION:In case the pressure in space 25, which is to be controlled, is lower than the pressure P, when a pilot pressure P is applied to No.1 chamber I by  a pilot pressure applying device 24, a diaphragm 22 shifts toward No.2 chamber II in the amount according to the pressure difference. As a result, a transmission member 23 sinks to push down the tip 9 of an inlet valve for positive pressure, and an orifice of the inlet valve for positive pressure. The orifice is closed when pressure air flows into the chamber II through this orifice to push up the diaphragm. In case the pressure in No.2 chamber II is lower than the pilot pressure P, the diaphragm 22 rises, and No.2 chamber II comes in contact with the negative pressure source through the orifice of the negative pressure inlet valve. When No.2 chamber II has attained the pilot pressure P, the diaphragm 22 is replace and both inlet valves are closed

Title: Gas-firing apparatus
Inventor: ISHIWATARI KAZUTOSHI
IPC: A21B1/28
Filed: 1994-07-07
Abstract: PURPOSE:To feed secondary air to the gas burner of a gas-firing apparatus only in a required amount so as to prevent the temperature and humidity in the firing chamber from decreasing with introduction of the outside air. CONSTITUTION:A secondary air-feeding pipe 30 for feeding secondary air is laid along the burner-pipe body 25 inside a firing chamber. The air fed into the secondary air-feeding pipe 30 enters a secondary air-distributing passageway 32 through a distribution hole 31 and is sent through a flow-straightening ribbon in a gap toward a gas-ejecting slot in the burner-pipe body 25. This constitution enables feeding secondary air to the gas burner only in a required amount and an excessive inflow of outside air into the firing chamber is suppressed. Therefore, the decrease of thermal efficiency which is due to fall of temperature and excessive drying of the inside of the firing chamber can both be suppressed.

Filed: 1988-06-24
Abstract: PURPOSE:To attain the supply of the constant voltage having the driving force and the reduced dependence on temperatures within an LSI by controlling the temperature characteristics of an emitter follower circuit via a temperature compensating circuit. CONSTITUTION:A temperature compensating circuit 3 consists of the 1st and 2nd voltage generating circuits 4 and 5. While a level shift circuit 2 consists of an emitter follower circuit including a bipolar transistor TRQ1, a diode D5 and a resistance R4. For the output V3, the current values or the emitter areas of both bipolar TRQ2 and Q3 are controlled so that the temperature characteristics are eliminated for the TRQ1 and the D5 of the circuit 2 set at the next stage. Thus the output voltage V4 can be kept at a fixed level. As a result, it is possible to eliminate such a problem where the temperature dependence is increased for the reference voltage and the generation is impossible for the constant voltage.

Title: Image detector
Inventor: MASUDA KATSUYUKI
IPC: F42B15/01
Filed: 1986-07-03
Abstract: PURPOSE:To obtain a detector which is small in size, and can transfer an image data at a high speed, by forming symmetrically upward and downward (right and left) an accumulating part and a transfer part, in both sides of a photodetecting part, respectively, and providing two image data output systems. CONSTITUTION:An image pickup part 151 of a CCD part 15 is placed in the middle and accumulating parts 152a, 152b are formed in both its sides, and also, transfer parts 152a, 152b are formed in both its sides, and they are constituted symmetrically upward and downward (right and left). In case when this CCD part 15 has been attached to an image detector 14, a distance from the center of the image pickup part 151 to the other end of one transfer part 153a (or 153b) is shorter than a conventional case, therefore, a radius of the detector 14 can be made smaller. Accordingly, by a portion which has made the detector 14 small in size, an effective area of a primary mirror 13 can be widened. Also, since the data are read out simultaneously by the transfer parts 153a, 153b, a frame transfer time can be shortened to about 1/2 of a conventional time. In this case, when a parallel processing is executed, the processing time can also be shortened, therefore, the tracking performance can be improved.
