Title: Liquid fuel feed system for burner
Inventor: TADA YUKIO
IPC: F23K5/06
Filed: 1979-06-06
Abstract: PURPOSE: To stabilize the operation of a flow divider and prevent a gas turbine from unexpected stopping, by providing an accumulator between a fuel pump and the flow divider.  
     CONSTITUTION: An accumulator 10 is installed between a flow divider 4 and a fuel pump 3 in a main fuel pipe 1. The outlet and inlet port of the accumulator is connected to the main fuel pipe through another pipe 11. A branch pipe 12 is coupled to a halfway part of the pipe 11. An air bleed valve is provided in a halfway part of the branch pipe 12 to bleed air when fuel is charged. The fluctuation in the difference between fuel pressure levels B, C held down by the pressure compensation, capacity compensation, impact buffer and pulsation damping action of the accumulator 10. As a result, the pressure difference between the front and rear of the flow divider 4 is kept appropriate and operation is continued stablely.

Title: Method and apparatus for continuously casting hollow cast billet
Inventor: YANAGIMOTO SHIGERU
IPC: B22D11/04
Filed: 1987-03-26
Abstract: PURPOSE:To smoothen casting surface of inner peripheral face and to obtain a hollow cast billet having uniform structure by holding coaxially a forcedly cooled core in inside of a forcedly cooled cylindrical mold, impressing gas pressure in inner peripheral face of poured molten metal between the mold and the core, forming annular space and casting. CONSTITUTION:At the upper end face of the core 16, a header 18 penetrating a cooling water introducing pipe 17 is fixed coaxially with the core 16. The lower face of the header 18 horizontally hangs over the upper end of the core 16 to outside, to form an overhang part 23. At contacting part of the upper end of the core 16 with the lower end of the header 18, the slit 24 is formed and in the slit 24, the pressurized gas is supplied from an introducing pipe 25 and gas pressure is impressed on the inner peripheral face of the molten metal at lower part of the overhang part 23. Further, a pressurized oil is supplied from an introducing pipe 26 and seeps through fine hole 26a of the core 16 to uniformly wet the outer peripheral face. Therefore, the contact of molten metal with the outer peripheral face of the core 16 is prevented and also thermal flow rate into the core 16 is reduced, and friction between the core 16 and the cast billet is reduced.

Title: Multiplex transmitter
Inventor: HASHIMOTO KYOSUKE
IPC: H04L12/40
Filed: 1989-03-24
Abstract: PURPOSE:To improve the transmission reliability by initializing the timing of a bit sending a signal at a point of time when a transmission signal is detected and monitoring the signal sent based on the initialized transmission timing. CONSTITUTION:Upon the receipt of a timing pulse signal Pb from a transmission timing circuit 2, a reception signal monitor circuit 8 monitors an inputted reception signal S'. The reception signal S' has a delay of tauc with respect to a sent signal S and since the transmission timing is initialized synchronously with the reception signal S', a margin of monitor (ta, tb) is always 1/2 bit or over even with the monitor in the timing of generation of a timing pulse Pb for the reception signal S'. Thus, the reception signal monitor circuit 8 monitors the reception signal S' sufficiently.

Title: Flashgun capable of daylight synchronized flash
Inventor: TSURUTA YUZO
IPC: G03B7/16
Filed: 1985-04-05
Abstract: PURPOSE:To obtain automatically the proper quantity of exposure even in daylight synchronization by selecting a minimum values which is common between two aperture values based upon distance information from a distance detecting circuit and stationary light measurement. CONSTITUTION:For example, a shutter is released and light is emitted by a discharge tube 1 through the operation of a preliminary light emitting circuit with a pulse from a pulse generator 16; and reflected light from a subject strikes on a photodetecting element and a voltage corresponding to its quantity of photodetection inverts outputs of some of comparators, e.g. 37-39. Then, when comparators 43 and 44 corresponding to the ambient brightness of a stationary light measuring circuit 64 are in an inverted state, a selector 55 decides a common minimum aperture F5.6 and a main discharge tube 2 emits light corresponding to F5.6 with a pulse from a delay circuit 17. Comparator groups 37-42 and 43-48 correspond to aperture values. Therefore, an aperture value is determined on the basis of aperture information based upon the ambient brightness and distance information to control the quantity of emitted light, and the quantity of light is controlled automatically even in daylight synchronization to obtain the proper quantity of exposure.

IPC: H01L21/302
Filed: 1987-03-27
Abstract: PURPOSE:To carry out the taper etching of an Al film without reducing etching selectivity by fitting a substrate having the Al film to an electrostatic chuck and by keeping the substrate at a specified temp. CONSTITUTION:The anode 2 and a water-cooled stage 3 as the cathode are placed opposite to each other in an etching chamber 1, an electrostatic chuck 8 is fitted to the stage 3 and a substrate (wafer) 9 having a formed Al layer to be etched is attracted to the chuck 8. The chuck 8 is formed by embedding flat electrodes 12A, 12B in silicone resin and the substrate 9 is electrostatically attracted to the chuck 8 by impressing positive and negative potentials on the electrodes 12A, 12B from variable DC power source 14, 15. Since the degree of contact between substrate 9 and the chuck 8 can be varied by changing the voltage between the electrodes 12A, 12B, the substrate 9 can be kept at <=60 deg.C during reactive etching. Thus, the taper etching of the Al layer is carried out with a conventional etching gas without reducing etching selectivity.

Title: Method for controlling mixing ratio at normal operation of instantaneous hot water feeder
IPC: F24H1/10
Filed: 1992-03-30
Abstract: PURPOSE:To improve the rising at a refeeding of hot water after a low normal operation has been carried out by a method wherein a mixing rate of a control valve is calculated and controlled in such a manner that a temperature at an outlet port of a heat exchanger under a normal operation condition may become the maximum temperature allowable within a range of setting temperature. CONSTITUTION:As a hot water feeding temperature is set, a cold water feeding temperature is detected, a mixing rate between hot water fed from a heat exchanger 1 and cold water fed from the heat exchanger 1 is calculated in such a manner that the temperature may become the hot water feeding-out temperature set by the cold water feeding temperature. Along with this calculation, a rate at the heat exchanger 1 is determined in such a manner that a mixing rate at this time may become the maximum temperature allowed within the set temperature, and then the control valve 5 is controlled. In this way, since the residual heating amount within the heat exchanger 1 once stopped becomes the maximum value allowed at the set temperature during the normal operation, the hot water feeding temperature at the refeeding of the hot water can be controlled by utilizing this high temperature. With such an arrangement it is possible to improve the rising of temperature when the hot water is re-fed out after the low normal operation.
