Title: Method and apparatus for processing gas or liquid
Inventor: JIEIMUZU JIYON DE UITSUTO
IPC: F24F1/00
Filed: 1990-11-30
Abstract: PURPOSE: To treat at least one of gas or liquid, by introducing liquid into the inside of a rotating head rotating the liquid in a housing, and radially outwardly discharging the liquid while dispersing a part of the liquid and furthermore introducing gas into the housing so as to make the gas come into contact with the dispersed and discharged liquid. CONSTITUTION: Liquid is introduced into a rotating head provided with liquid discharge means on a periphery thereof. When the head is rotated in a housing 7, the liquid is approximately radially and outwardly discharged from the head toward the wall of the housing 7 and a part of the liquid is dispersed. Furthermore, gas is introduced into the housing 7 and the gas is moved by the movement of the liquid to be discharged and is brought into contact with the dispersed and discharged liquid. Here, the liquid is pumped up into the rotary head from a discharge water chamber 11, and after being discharged from the rotating head, the liquid returns and is recovered in the discharge water chamber 11 and while the gas is sucked into the inside of the housing 7 along with the movement of liquid.  It is preferred that gas is brought into contact with the radial flow of liquid substantially perpendicular to direction of the flow of liquid. Due to such a construction, at least one of liquid or gas is treated.

Abstract: PURPOSE: To provide a method for producing a high-purity synthetic quartz glass uniformly containing aluminum and hardly containing OH group and Cl group and having high temperature viscosity. CONSTITUTION: This synthetic quartz glass is obtained by hydrolyzing a solution obtained by mixing and stirring a methylsilicate and aluminum alkoxide, hydrolyzing the resultant solution in the presence of ammonia to afford silica particles containing aluminum, dehydrating the silica particles by solid-liquid separation, further heating the silica particles to decarbonize the silica particles, sintering the decarbonized material to afford a synthetic quartz glass ingot, grinding, sieving, magnetically grading and purifying the synthetic quartz glass ingot containing aluminum to provide the synthetic quartz glass powder and melting the powder under ordinary pressure, pressure or vacuum.  When the glass is produced, in the sintering step, the glass powder is once transferred to crystals of α-cristobalite and the crystals are melted and vitrified under vacuum or reduced pressure at 1800 to 1950 deg.C.

Title: Multi-strobo flash photometry system
Inventor: MOROHASHI DAIKICHI
IPC: H04N5/238
Filed: 1991-11-20
Abstract: PURPOSE:To reduce number of times of strobo flash by implementing correction processing with an optimum coefficient decided based on a video signal level (photometry information level) so as to attain exposure control with high accuracy. CONSTITUTION:When preliminary flash for photometry is implemented for lots of number of times, the level is converged to a proper exposure level but the capacitance of a main capacitor has a limit, required power for strobo flash cannot be obtained at the actual photographing so long as the photometry flash is not decreased. In order to set a video signal to an object proper level, the strobo flash luminous quantity is decided so as to correct a difference between photometry information M obtained by preliminary flash and an object proper level to attain dimmering. In order to correct the level of the photometry information M to the proper level, when the predetermined correction allowable range is set, a multiplier section 6 multiplies a prescribed coefficient G with picture data stored in the picture memory 5 and the video signal to be sent to a digital process section 7 is set to the optimum level.

Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain a catalyst which has high activity and gives an alkoxylated product of a narrow homologue distribution by reacting a chelate-forming anionic or nonionic phase transfer catalyst with an alkaline earth metal compound in the presence of a compound which can be alkoxylated. SOLUTION: The precursor of an alkoxylation catalyst is obtained by reacting a chelate-forming anionic or nonionic phase transfer catalyst with an alkaline earth metal compound in the presence of a compound which can be alkoxylated. The phase transfer catalyst is a compound which is expressed particularly by a formula of C8 -C22 -alkyl-O(AO)x -B (wherein A is C2 H4 or C3 H7 , B is hydrogen or CH2 COOH etc., (x) is 2-10). Since an alkaline earth metal sulfato complex is highly active, the reaction time of alkoxylation can be reduced largely, and the product indicates very narrow homologue distribution.

Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To provide a facsimile machine which can delete an unnecessary file, when the capacity of an image information accumulating part storing received data is not sufficient. SOLUTION: Received data is converted into sound and text data (S102). When the capacity of image information accumulating part for storing converted data is not sufficient, a facsimile control part 6 recognizes that capacity shortage in text communication (S103) and selects whether it is informed to a user (S104). The informed user decides whether the unnecessary file is to be deleted (S105). When the file is to be deleted, the file is deleted (S106) and a processing is terminated. When the user does not delete the file, data which are previously stored are outputted in the order starting from the oldest one (S107) and the processing is terminated. When the capacity shortage is not informed to the user (S104: N), data which are previously received and stored are outputted in the order from the oldest one (S107), and the processing is terminated.
