Title: Device and method for supplying slurry fuel of mixed coas and water for pressurized fluidized bed type boiler
Inventor: TOUKAWA KENJI
IPC: F23C10/16
Filed: 1993-03-05
Abstract: PURPOSE:To keep a desired combustion performance of a pressurized fluidized bed type boiler by a method wherein an unstable state of flow rate of supplying CWP or a closing trouble in a supplying pipe is prevented. CONSTITUTION:An increased viscosity caused by a variation in nature of a coal water mixed slurry (CWP) and a pressure loss in a CWP supplying pipe 3 are detected by a pressure difference sensor 10. As they become predetermined dangerous values, water is fed and controlled to be supplied to the corresponding locations with a water feeding pipe 12, thereby an unstable state of a flow rate of CWP supplying during an operation of the pressurized fluidized bed type boiler 101 is eliminated and a closing of the supplying pipe 3 can be prevented, so that a combustion performance of the boiler 101 is not substantially influenced. Although a closing trouble of the sensor device itself for the pressure loss can be expected during supplying of CWP 120 of high viscosity, even in that case, a water supplying control for the supplying pipe 3 is carried out under a combination of O2 and NOx concentration sensor 14 for the discharged gas of the boiler 101, resulting that back-up for the device may easily be performed.

Title: High-pressure servo-valve
Inventor: ICHIYANAGI TAKESHI
IPC: F16K31/42
Filed: 1980-04-09
Abstract: PURPOSE: To prevent the leakage of a liquid even if it has a high-pressure and low- viscosity and to improve a contamination-proof property, by a method wherein a negative pressure is always applied to a main valuve of a subject valve for controlling a high-pressure fluid, a control port is formed in a poppet surface, and the main valve is driven by means of a bobbin.  
     CONSTITUTION: An initial pressure Ps is applied to a surface of a sleeve 13 through an oil path 10, an orifice 11, an oil chamber 21, an oil hole 12, a perforation 6. Through the leftward movement of a bobbin 3, the pressure in the oil chamber 21 rises, the sleeve 13 moves leftward, a main valve 14 moves leftward, and a poppet 16 opens to control discharge to Ps→Pc. In case it moves in the reverse direction, a distance between a poppet 15 and the sleeve 13 is widened to the rightward movement of a nozzle 20, the poppet 16 engages a sleeve edge 22, and an oil pressure Pc is connected to a tank port 23. This causes the control ports 15, 16 to act as a poppet surface, allows the valve to be prevented from the influence of contamination, causes a constant application of a negative pressure to a main valve, and permits the prevention of the leakage of a fluid even if it has a high-pressure and a low-viscosity.

Filed: 1982-03-23
Abstract: PURPOSE:To enable the estimation of the thickness of a thin film formed on an optically transparent base plate at ion etching time for thinning the film when observing the thicknesswise direction of the film by an electron microscope by inserting suitable semiconductor piece between two equal samples formed with the film. CONSTITUTION:A silicon semiconductor 14 is inserted via adhesives 13, 15 to between equal samples of silicons 12, 16 epitaxially grown on sapphire substrates 11, 17 and symmetrically bonded. Since a light gradually passes a semiconductor of silicon or the like in the vicinity of 1 micron of thickness, the thickness can be estimated, if there is a surface to be etched of several hundreds mum of thickness in case of ion etching. Accordingly, thicknesses of the thin films 12, 16 can be estimated by observing the thickness of the part of the semiconductor 14 bonded in case of ion etching by empolying the semiconductor 14 at the same etching speed as that of the same silicon as the films 12, 16. Since the surfaces of the films 12, 16 are protected by the semiconductor 14 via the adhesives 13, 15, defects of the films 12, 16 at polishing time can be avoided.

Title: Production of glass gob
Inventor: KISHI KAZUYUKI
IPC: G02B3/00
Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To produce a glass gob having a stable small particle diameter to be a preformed material of a fine optical glass element at a high production rate. SOLUTION: A molten glass melted in a melting furnace 1 is discharged from a nozzle 2 as a continuous stream. The flow rate, flow velocity, viscosity, etc., of the molten glass are regulated to thereby change the molten glass flowed down as the continuous stream into a glass gob in the form of droplets falling in one row in the course thereof. The glass gobs falling in the form of droplets in one row are received in a heated oil 4a in a liquid vessel 4 and recovered as the glass gobs. Thereby, the glass gobs having a much smaller diameter than that obtained by directly dropping the molten glass from the nozzle 2 can be obtained. The production rate based on one glass gob is higher than that formed by directly dropping the molten glass from the nozzle 2. Since the continuous stream is not cut with a cutting blade, shear marks, etc., are not formed in the glass gobs.
