Title: Control method for pressure of furnace of induced draft fan
Inventor: OGAUCHI TOSHIO
IPC: F23N3/04
Filed: 1981-10-05
Abstract: PURPOSE:To prevent the change of the inside of the furnace into negative pressure by  enabling both operation at high and low speed through the changeover of a motor driving the induced draft fan into a pole change type, interrupting a power supply at the  high speed side by fuel throttling signals and rapidly throttling the damper of an entrance and exit. CONSTITUTION:Output from a damper throttling signal generator 18 is inputted, a  damper control drive 19 is operated through a signal changer 17 having the changeover function of control signals, an inlet damper 8 is opened and closed, and the pressure of  the furnace is controlled to desired value. When a fuel throttling command is emitted,  the power supply at the high speed side is interrupted and the inlet damper is throttled  so as to throttle the inlet damper 8 at full speed when the induced draft fan 9 is  operated at high speed. When the number of revolution of the draft fan 9 lowers and reaches the number of revolution at the low speed side, a power supply at the low  speed side is turned ON while the inlet damper shifts to the predetermined furnace-pressure automatic control mode. Accordingly, a phenomenon of which the iside of the furnace is rapidly changed into negative pressure is prevented by throttling the damper at the same time as the draft fan 9 is interrupted.

Title: Controlling method of heat source demand
Inventor: OGAWA TOSHIAKI
IPC: F24D11/00
Filed: 1978-12-22
Abstract: PURPOSE: To provide an adeguate method of controlling a heat source demand by actually measuring the quantity of heat received at chilled or hot water from a load to be air conditioned and suitably estimating the quantity of heat to be used thereby.  
     CONSTITUTION: The quantity of heat received by a local air conditioner receiver 2 is detected by a heat flow meter 1 to thereby estimate the quantity of heat on the basis of the set value from a setting potentiometer 5 in an arithmetic controller 3. When the quantity of heat MX to be expected for use is larger than a set target value MTS in a step 13, an alarm message is fed to a CRT display unit 4 in a step 14, while when the quantity of heat MU used at present is larger than the target upper limit value MT, a break instruction is fed to a processor 9 in response to the priority. After unit time is further elapsed, they are again compared, and when the MU is larger than the MTS, it is controlled in two steps. Thus, the maximum heat load can be used without exceeding the contracted quantity of heat.

IPC: C23C14/24
Filed: 1987-06-26
Abstract: PURPOSE:To reduce variance of film thickness at the time of filling a hole by irradiating the inside of the hole wherein a metal film is to be formed, and detecting the endpoint of the selective growth of metals from the variations in the reflected light. CONSTITUTION:Raw gases are introduced into a water-cooled reaction vessel 8 from cylinders 1 and 2 through flow controllers 3 and 4 and a light shielding plate 11. Light is radiated from a water-cooled halogen lamp 7 provided with a reflecting mirror, and passed through an irradiation window 9 to heat a wafer 12. When a metal film is grown in the hole wherein a metal film is to be grown, He-Ne laser light 17 is radiated through two transmission windows 16, and the reflected light is measured by a photosensor 18. When the light 25 hits on a nail head 24, the reflectivity of the light is lowered as compared with the reflectivity before the growth film on the nail head 24 overflows due to the light scattering on the nail head 24. Accordingly, the endpoint of the film growth can be detected by detecting the variations in the reflectivity.

Abstract: PURPOSE:To prevent the generation of void and to obtain a semiconductor device having a superior pressure withstanding property by a method wherein after the electrode plates consisting of  a composite material of copper-carbon fiber are covered with silver and degassing treatment is  performed in a vacuum, the electrodes are adhered to the semiconductor substrate with a lead-tin  alloy solder. CONSTITUTION:An Ag plated electrode consisting of a composite material of Cu-carbon fiber  discharges small quantity of gas at a low temperature. Therefore a solder solution wherein the  soldering temperature is made to be at the semifused state with the solid phaste and the liquid  phase of Pb-Sn solder coexisting, moreover, the composite material is degassed at the temperature  over the melting point of the solder and Ag is evaporated to the Si substrate to make the solder  wetting favorable. When the electrode is soldered to the substrate with the solid-liquid coexisting  liquid, the solder does not flow out of the adhering part, and the parallelism and the thickness of  the solder can be controlled. When the soldering part is pressed by pressing the substrate or the  electrode plate at a high temperature lower than the solder phase line of the solder, Ag easily  forms solid solution with the solder, the thickness of the solder layer and the parallelism become  fevorable and the generation of voide is reduced much more, and a simplified package type  device having a superior pressure withstanding property can be obtained.

Title: Device and method corresponding to radio reception data deviation
Inventor: KAMEI JUNICHI
IPC: H04L7/04
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To automatically output synchronized data by confirming that step-out owing to an error does not exist, executing second and third CRC operations on a point faster than a synchronous point by one period of a reception clock or delayed by one period and confirming the matching of the operation result of the first to third CRC operations with CRC data. SOLUTION: A demodulation part 1 demodulates reception data and outputs it as serial data. A synchronism detection part 2 executes a CRC operation with a reception reference signal as a reference by using serial data generated in the demodulation part 1. When a CRC operation result does not match CRC data, the CRC operation is repeated until the result of the CRC operation matches CRC data while a point where the CRC operation is started is shifted by one period of a reception clock from the reception reference signal. When the CRC operation result matches CRC data, synchronism with a transmission side is judged to be decided and the start point of the CRC operation is set to be a synchronous point.

Title: Production equipment of crosslinked foamed polyolefin-based resin sheet
Inventor: FUKUNAGA TOSHITAKA
IPC: B29C48/08
Filed: 1991-06-28
Abstract: PURPOSE:To minimize temperature rise in an extruder and fluctuation of delivery by a method wherein the length of the metering zone of the extruder is reduced so as to satisfy a specified formula determining the relationship between the length of the metering zone and the outer diameter under the condition that a gear pump is arranged in order to compensate the reduction of the length of the metering zone. CONSTITUTION:A gear pump 13 is arranged between an extruder 11 and a mold. Further, a breaker plate 24 is arranged at the tip of a cylinder 21 so as to serve the portion on the base end side over the required length L as a metering zone 25. Let D be the outer diameter of a screw 22, then L is set to satisfy L<=4D, resulting in making the length of the metering zone 25 shorter as compared with its conventional length. The resulting lowering of the molten resin force-feeding function and metering function of the metering zone 25 is compensated with the gear pump. In proportion to the reduction of the length of the metering zone 25, the pressure of resin at the tip of extrusion becomes lower, resulting in checking the resin temperature rise in the extruder 11 and the change of delivery from the extruder 11.
