Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To provide the crucible structure capable of prolong the service life of a graphite crucible and reducing the running cost of a single crystal pulling-up device. SOLUTION: In the single crystal pulling-up device having this crucible structure, a quartz crucible 11 for storing a semiconductor melt and a graphite crucible 35 which is used for receiving and supporting the quartz crucible 11 and divided into sections in the circumferential direction are placed in a chamber. Also, grooves 37a, 37b and 37c, each extending in the circumferential direction are formed in the inner peripheral surfaces of curved corner parts at the bottom (parts liable to be worn) of constituent members 35a, 35b and 35c of the graphite crucible 35 respectively and an annular replacement member 36 is fitted into the grooves 37a, 37b and 37c. As the material of the replacement member 36, the same isotropic graphite as the material of the graphite crucible 35, a carbon fiber reinforced carbon material, or the like, can be used.  With the progress of production of a single crystal, wear of the replacement member 36 progresses and when this wear reaches a specified level, by only replacing the replacement member 36, the service life of the graphite crucible 35 can be prolonged.

Abstract: PURPOSE:To simplify an optical system and to easily decide a flaw at low cost by projecting incident light through the through hole of a hologram lens, converging scattered light which is reflected irregularly at the flaw part through the hologram lens, and detecting the light. CONSTITUTION:A collimator lens 3 collimates the laser light 2 emitted by a laser light source 1 into a parallel light beam and a reflecting mirror 5 deflects the light 2 passed through the lens 3 at right angles to the surface 4a of the object 4 of inspection.

Title: Treatment of exhaust gas by irradiating radiation rays
Inventor: AOKI SHINJI
IPC: B01D53/74
Filed: 1987-12-10
Abstract: PURPOSE:To reduce the amt. of NH3 leaked by adding NH3 to exhaust gas contg. SOX and NOX by a smaller amt. than the amt. of NH3 required to denitrate and desulfurize the gas, irradiating radiation rays on the gas, adding an alkaline substance and capturing ammonium sulfate and ammonium nitrate with a dust collector. CONSTITUTION:Exhaust gas 2 contg. SOX and NOX from a boiler 1 is passed through a cooling tower 3 and NH3 is added to the gas 2 through a flow rate regulating valve 6 by a smaller amt. than the amt. of NH3 required to remove the SOX and NOX. The required amt. is calculated with an SOX analyzer 14, an NOX analyzer 15 and an exhaust gas flowmeter 16. The gas 2 is then introduced into a reactor 7, where radiation from electron beam generators 9 is projected on the gas 2 to produce ammonium sulfate and ammonium nitrate as by-products. After the by-products are captured with an electrostatic dust collector 11a, an alkaline substance such as CaO is added to the gas 2 and allowed to react with the unreacted NOX and SOX. The resulting reaction products are captured with a bag filter 11b.

Title: Onboard power supply
Inventor: NIIMI YUKIHIDE
IPC: H02H7/12
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To prevent the secondary failure of a series type regulator in a rear circuit that may be caused by abnormalities including the short circuit of a chopper type regulator in a front circuit. SOLUTION: A chopper type regulator 13 and a series type regulator 14 are connected in series to a battery 11 via an ignition switch 12. An output voltage comparing circuit 30 is provided to determine whether or not the output voltage of the chopper type regulator 13 is higher than a given voltage. The output of this output voltage comparing circuit 30 is applied to the base of a forced turning off transistor 35 via a delay circuit 34 that removes noise and the like. If the chopper type regulator 13 fails on a short circuit, its output voltage rises up to almost the same level of the battery voltage to invert the output of the output voltage comparing circuit 30 to the high level. This makes the forced turning off transistor 35 turned on so that the series type regulator 14 is forcibly tuned off.

Filed: 1988-12-12
Abstract: PURPOSE:To save time for recovery by executing a job from a processing step executed immediately before the generation of a fault or from a leading processing step in accordance with the existence of the entry of the job. CONSTITUTION:When a job 1 is started, an abnormality detecting means 3 refers the contents of a storage device 8 to identify the existence of the entry of the job 1. Since the existence of the entry means the generation of a fault due to any cause prior to the execution of the job 1, a fault generating position analyzing means 4 analyzes the step, the file and its position updated at the generation of the fault based upon the contents of the entry of the job 1 which are stored in a storage device 8 and transfers the analyzed result to a job execution control means 5. The means 5 skips the processing up to the state executed immediately before the generation of the fault in the job 1 and restarts the processing from the part to recover the job 1 so that the succeeding processing state becomes similar to the normal state set up before the generation of the fault. Consequently, recovery work requiring considerable time in an ordinary method can be completely removed.
