Abstract: PURPOSE:To improve reaction efficiency, yield or the like by allowing a gaseous starting material to flow along the inner wall of a reactor in helical form to mix and allow to react when producing nitrogen trifluoride by reacting fluorine gas with ammonia gas in vapor phase. CONSTITUTION:The raw material blowing pipes 1 and 2 are connected to the reactor 6 so as to enable the gaseous starting material to blow in tangential direction of the cylindrical part of the reactor 6, and ammonia gas and fluorine gas, if necessary adjusted their conc. with a dilution gas, are injected into the reactor 6 from the raw material blowing pipes 1 and 2, are allowed to flow along the inner wall of the reactor 6 in helical form in the inside of the reactor 6 and are sufficiently mixed to allow to react. Next, the reacted gas is drawn out from the formed gas draw-out pipe 3 and is introduced into the gas scrubber 4 to clean, and then, formed nitrogen trifluoride is recovered by the recovering device 5. A solid part of the by-product is stored in the storage vessel 7. As a result, the gaseous starting material is sufficiently mixed and clogging of the reactor and pipe line is eliminated.

Title: Clock generation circuit
Inventor: SUGITA JUNKICHI
IPC: G11B11/105
Filed: 1994-11-09
Abstract: PURPOSE: To regenerate a clock stably by providing means for controlling the oscillation phase of an oscillator depending on phase information detected through a phase information detection means. CONSTITUTION: An A/D converter 2, a peak detector 3, an amplitude detector 4, and a phase difference detector 5 are controlled by means of a timing generator 9 based on a clock signal generated from an oscillator 8. The A/D converter 2 digitizes a reproduction RF signal being picked up through an optical pickup and delivers a sampling value to the amplitude detector 4. The phase difference detector 5 comprises a subtractor 51 to be fed with sampling values from first and second registers 41, 42 in the amplitude detector 4, an adder 52 to be fed with an output from the subtractor 51, a register 53 and a comparator 53 to be fed with an output from the adder 52.  When a defect is detected by any one of the peak detector 3, the amplitude detector 4 or the phase difference detector 5, a timing generator 8 discards newly sampled phase difference information and sustains the phase difference information at the previous sampling moment, as it is, until a next synchronous pattern appears thus suppressing disturbance of output clock from a PLY, caused by a defect.

Title: Method for degreasing powder molded product
Inventor: MATSUMAE TOSHIYUKI
IPC: F27B17/00
Filed: 1989-10-23
Abstract: PURPOSE:To obtain a powder molded product of good quality while controlling the volume of the decomposition gas of an org. binder and preventing the fault in a degreasing process by heating the powder molded product under the pressure in a furnace lower than atmospheric pressure and controlling the pressure in the furnace corresponding to the temp. in the furnace. CONSTITUTION:A vacuum exhaust part 2 is equipped with a control valve 5 controllable in its conductance and a rotary pump 6. When the vacuum degree in a furnace is kept constant to perform heating when a powder molded product is degreased, the org. binder in the powder molded product thermally decomposed with the rising of temp. to generate decomposition gas but, when temp. further rises, the thermal decomposition of the org. binder becomes vigorous to generate a large amount of the decomposition gas. The volume of the gas generated at this time suddenly expands by vacuum action and, when the degreasing process is completed in this state, the molded product is broken to pieces by the decomposition gas expanded in the powder molded product. Therefore, a program lowering the vacuum degree in the furnace within a temp. region where the decomposition of the org. binder is violent is set to perform degreasing.

Title: Image forming device
Inventor: HIROSHIMA KOICHI
IPC: G03G15/16
Filed: 1988-11-02
Abstract: PURPOSE:To always obtain stable and fine transfer irrespective of environments and the size of a material to be transferred by controlling with constant current at the outer region of exposure that is outside of picture region. CONSTITUTION:A power source 4 controls with constant current avoiding an APC (light intensity correcting) region which corrects light intensity by scanning a laser 5. Since this current inflow into bright electric potential part of the APC region is interrupted, a plus memory does not remain on image carrier 1 and the base fogging of the picture caused by this memory can be interrupted. Thus, stable and fine transfer is always maintained irrespective of environments and the size of a material to be transferred and a fine picture can stably be obtained.

Title: Coating material-spraying apparatus
Inventor: HARA MASUMI
IPC: B05B12/08
Filed: 1993-10-06
Abstract: PURPOSE:To simply and certainly perform special spraying work by the ejection of a very small amt. of compressed air in succession to usual spraying work only by operating an air adjusting valve on the spraying spot. CONSTITUTION:When a front valve disc part 37 is allowed to approach a first valve seat 31 by forwardly advancing a needle valve 33 as shown by a solid line, the flow rate toward an output port 25 is throttled. Since a second valve seat 32 is opened accompanied by this operation, the compressed air limited in the outflow toward an air nozzle 4 is discharged to the outside from a discharge port 42. Therefore, the supply flow rate of the compressed air itself is avoided from reduction and a sensor is not operated and the driving of a motor, that is, the supply of a coating material is continued. By this constitution, spraying work by the ejection of a very small amt. of compressed air is performed. In order to restore usual spraying work, the needle valve 33 may be allowed to retreat in the direction shown by a dotted line.
