Title: Formation of uniform beam, and transmission and irradiation devices for uniform beam
Inventor: ADACHI KOZO
IPC: H01S3/00
Filed: 1989-05-11
Abstract: PURPOSE:To assure effective laser transmission by making uniform laser beam intensity distribution by a multi-face prism. CONSTITUTION:Laser light emanating from a laser oscillator device 1 is made uniform by a multi-face prism 6 after passing through an exit window 5 and a cylindrical lens 9. Further, the laser light enters an optical fiber 4 for transmission after passing through an aperture 2 and a fiber holder 3. Herein, provided Gaussian distribution laser light enters a two-face prism 6, for example, light beams existent between lines A and B and between lines B and C are refracted inwardly on slanting surfaces 6a, 6b of the prism 6 and made uniform because the characteristics of the surfaces AB and CB are synthesized at a point D separated a distance x therefrom.

Filed: 1988-05-17
Abstract: PURPOSE:To provide the most suitable environment which is the most preference of a dwelling person without feeling any variation in environment when a temperature of surrounding atmosphere is varied or when a feeling state is inputted by a method wherein a control device including means for determining a heating capability, means for performing a high air speed operation, means for performing a low air speed operation and means for varying a first set temperature and a second set temperature is provided. CONSTITUTION:A micro-computer 10 has means for determining a temperature to be set, means for determining an amount of air to be fed and means for determining a blowing area. A temperature difference DELTATU between a first detected temperature TU and a first set temperature TUC which are temperatures at an upper part in a room is calculated and a heating capability is determined and a heater device is operated. Another difference in temperature DELTATL between a second detected temperature TL and a second set temperature TLC which are temperatures at a lower part in a room is calculated, a positive value and a negative value of this difference in temperature are discriminated. When the second detected temperature TL is higher than the second set temperature TLC, a blowing area is widened to decrease an amount of blowing air so as to perform a low air speed operation. In turn, when the second detected temperature TL is lower than the second set temperature TLC, the blowing area is narrowed at a step S016 and then a high air speed operation is carried out while an amount of air is increased.

Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent an accident resulting in physical injury due to the cutter blade of a large cutter by concealing the safety covers in such a state as clamped from both sides like a sandwich, and projecting the cutter blade through space between the safety covers for cutting a workpiece. SOLUTION: When an operation handle is pushed down to continue cut a cutting workpiece 6, the expansion parts 11 of a fixed cover 7 slide on the bent internal surface of safety covers 8, thereby laterally pushing and expanding the safety covers 8 toward both sides. Then, a cutter blade 2 sequentially projects through space between the safety covers 8 for cutting the workpiece 6. Also, when a cutting process is over and the operation handle is raised, the cutter blade 2 moves upward and is housed within the safety covers 8 according to a reversed order, thereby being completely concealed. According to this construction, no danger takes place, even upon the occurrence of the racing of the cutter blade 2.

Title: Method for removing unburned carbon from crude gas cooler and apparatus therefor
Inventor: KOYAKE YASUHIRO
IPC: B08B3/02
Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To decrease the amount of unburned carbon mixed into slag by introducing a gasification gas produced in a gasification oven into a crude gas cooler to cool the gas and simultaneously blowing high-temperature high-pressure steam to a heat transfer pipe to reduce and remove unburned carbon deposited on the heat transfer pipe. SOLUTION: A crude gas produced in a gasification oven 10 is introduced into a crude gas cooler 14. The crude gas contains ash and unburned carbon, which are deposited on the surface of a heat transfer pipe 17. The ash deposited is swept off by blowing high-temperature hig-pressure steam from a steam soot blow pipe 18 through a nozzle 19 to the heat transfer pipe 17 and is discharged, together with slag, through a discharge port 16 formed at the lower side. On the other hand, the unburned carbon swept off together with the ash reacts with steam to be gasified, Thus, the content of unburned carbon in slag discharged through the discharge port 16 is decreased, and the gas is made usable as a fuel for a gas turbine.

Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To prevent frame information from being inverted when an odd number of missing signals is in existence in a vertical synchronizing signal in the device digitizing an analog video signal, processing the signal in the unit of frames and recording the processed signal. SOLUTION: When one vertical synchronizing signal is missing as the result of separation of the signal by a synchronizing separator and an odd/even discrimination section 11, a microcomputer 1 gives an enable signal VD.EN to prevent passing of a succeeding vertical synchronizing signal top the missing signal to an AND gate 13. Thus, two congestive vertical synchronizing signals VD' are missing form the AND gate 13. As a result, the fame information generated by a frame PLL circuit 14 is not inverted.
