Title: Fuel supplying device for thermal power plant boiler
Inventor: KICHIJIMA NORIO
IPC: F22B35/00
Filed: 1990-01-26
Abstract: PURPOSE:To minimize influence on a water-cooled wall outlet temperature and to suppress variation of main steam temperature efficiently by a method wherein the flow rate of fuel is controlled for a plurality of burners located at the upper stage side near an over-heater and located at the lower stage and then a water-to-fuel ratio is corrected only for the flow rate of fuel in the upper stage burner. CONSTITUTION:In the event that the number of burners is five, for example, the burners are divided into upper three stages near a final over-heater and opposite lower two stages. A volume of fuel proportionally distributed to the two burner stages is supplied to the lower two stages (a stage A and a stage B) under a boiler input instruction, a water-fuel ratio is added to a value in which a boiler input instruction is proportionally distributed to the upper three stages (a stage C, a stage D and a stage E) for three stages of the burner and then this is supplied as fuel. With such an arrangement, it is possible to reduce influence against a water-cooled wall of which temperature is governed by the lower stage burner fuel and further improve the effect of water-to-fuel ratio against a final over-heater of which temperature is governed by the upper stage burner fuel. Actually, in the event that the fuel exceeds the upper limit and the lower limit of a burner volume due to a substantial variation of load, values of proportional distributors 36 and 37 are corrected in response to the actual number of burners due to the fact that the number of burners is also varied.

Title: Method for generating sound ray signal and ultrasonograph
Inventor: SUZUKI YOICHI
IPC: G01N29/06
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of capacity for direction analysis in a deeper place utilizing merits of the image softener method. SOLUTION: An adding machine ka of a load adding part 6 is to add the product of an RF signal Rb multiplied by the load coefficient αto an RF signal Ra to generate a composite RF signal Sa. And the adding machine ka of the load adding part 6 also adds the product of an RF signal Ra multiplied by the load coefficient α to the Rf signal Rb to generate a composite RF signal Sb. A load coefficient generation part 5 sets the load coefficient a at zero when the focal length is small, and at one when the focal length is large, and sets the load coefficient α between zero and one when the focal length is medium. Therefore, the opening is substantially wider in a deeper place, while the image softener method works in a shallower place. So high quality images can be obtained from shallower places through deeper places.

IPC: H01S5/00
Filed: 1992-01-31
Abstract: PURPOSE:To realize a simple and low-cost transmitter-receiver module or module for multiplex communications by using part of a laser array as a photodiode (light receiver). CONSTITUTION:A semiconductor laser array 1 includes a light source section A and a light receiver section B. The light beam from the source section A enters a photocoupler 3 formed on a planar waveguide substrate. Then, the beam travels in a common waveguide 5 connected to an optical fiber 4 and reaches another module. On the other hand, the light beam transmitted from the corresponding module through the optical fiber 4 travels in the common waveguide 5, and it enters the receiver section B through the photocoupler 3 of the laser array 1. Since the laser array functions in part as a photodiode (light receiver), it can be used for both transmitting and receiving, and for frequency-multiplex communications.

Abstract: PURPOSE: To promote the separation of solid from liquid by providing a sludge discharger having a zig-zag form of aperture in the radial direction in the sludge discharging port inside a drum and also a chemical injection pipe with an opening toward the inside of the apparatus provided with a raking-up and dehydrating mechanism.  
     CONSTITUTION: Precipitate discharged from a rotary drum 101 into a cylinder 126 drops slidingly along the first conical face (b) of the cylinder 126 and then deposits on a cylindrical face (c), during which period a floculant is spread over the pricipitate from a chemical injection pipe (p). Then, the precipitate is pushed and dropped into an annular space G 1  through an aperture g 1  between an end plate 133 and the tip of a cylinder 126 along the conical face (d) at the top of the cylinder 126. Then, it goes on the cylindrical face (c) of the cylinder 130 in the opposite direction to the cylinder 126 and then drops into the outside annular space G 2  through the aperture g 2 . In this way, the precipitate passing through the aperture in a zig- zag way drops lastly onto the inner surface of the rotary drum 201. Thus, the time of reaction between the flocculant and the precipitate can be made longer and therefore, the separation of solid from liquid can be accelerated.

Title: Constant vacuum type carbureter
Inventor: YAMAZOE HIROSHI
IPC: F02M7/17
Filed: 1984-01-31
Abstract: PURPOSE:To reduce the bending moment of a plate-like part which is made out of the guide part of a friction piston type carbureter and make the guide plate thinner by bringing the contact point of the guide plate with a groove to a point close to the center of a piston. CONSTITUTION:The diameter of a friction piston 20 which contains a needle at the lower end of the center thereof is made shorter than the diameter of an intake shell. A piston 20 is moved up and down by guiding a guide plate 20b provided at both sides of the piston 20, along a guide groove 11 formed on the internal face of the intake shell. If the guide plate 20B is shaped as to get thinner toward the end part thereof or as to have a noth S at the end part thereof, the contact point of the guide plate 20B with the groove 11 can be displaced near the center of the piston. Resultantly, the bending moment acting on the plate is reduced and the concentrated stress acting on the joint part of the plate with the piston is attenuated, on account of which if thin, the plate will not be broken.
