Title: Fluorescent lamp
Inventor: TATEIWA TOSHIAKI
IPC: H01J61/46
Filed: 1990-01-31
Abstract: PURPOSE:To enhance the initial output of a fluorescent lamp and improve the durability of the light flux of the lamp by mixing particles of boron compounds as a specific amount of boric acid compounds in silicate phosphor when silicate phosphor is used in the fluorescent lamp. CONSTITUTION:Particles of boron compounds are mixed in particles of silicate phosphor in a ratio of more than 0.1 and less than 10 parts by weight to 100 parts by weight of silicate phosphor. Mixing of particles of boron compounds in particles of silicate phosphor decreases attachment of mercury on the surface of particles of zinc silicate phosphor whereby deterioration of the silicate phosphor is remarkably improved. Maintenance of the light flux of a fluorescent lamp i.e., the condition of the light flux after lighting of the lamp for 100 or 500 hours against the initial light flux of the lamp is improved to a large extent as compared to when particles of boron compounds are not mixed. Because particles of boron compounds form a white reflecting layer, the initial light flux of the fluorescent lamp which uses silicate phosphor having particles of boron compounds mixed therein is higher as compared to when particles of boron compounds are not mixed.

Abstract: PURPOSE:To inexpensively obtain the title compound useful as a phase-transfer catalyst, etc., in high purity, by dissolving quaternary ammonium methyl carbonate salt in water, removing the produced methanol, then mixing the resultant solution with an organic acid anhydride and removing carbon dioxide. CONSTITUTION:A quaternary ammonium methyl carbonate salt (e.g., tetramethyl ammonium) is dissolved in water having 0.1-100, more preferably 0. 5-10 weight ratio based on the above-mentioned carbonate salt. Then the produced methanol is removed out of system and then the salt solution is mixed with an organic acid anhydride (e.g., acetic anhydride or propionic anhydride). Thereafter, the produced carbon dioxide is removed out of system to provide quaternary ammonium organic acid salt without producing an organic acid methyl ester.

IPC: A01F12/00
Filed: 1988-02-02
Abstract: PURPOSE:To prevent clogging of receiving mesh even if planted culm has high water-content, by forcibly reciprocating a receiving mesh at high speed on a path under a threshing cylinder along the circumferential direction of the cylinder and, at the same time, driving a blower of a reap-pretreatment part to remove dew-drops. CONSTITUTION:Wind for removing dew-drops is blasted with a blower 25 of a reap-pretreatment part A against planted culm K immediately before reaping and, at the same time, a receiving mesh placed under a threshing cylinder 10 is forcibly reciprocated at a high speed on a path along the circumferential direction of the threshing cylinder. The clogging of the receiving mesh hardly occurs even if the planted culm contains a large amount of water.

Title: Cooling method of body
Inventor: HASEBE MORIKUNI
IPC: F25D9/00
Filed: 1980-02-28
Abstract: PURPOSE: To cool a body to a desired temperature by injecting a gas in a fluidized state having a temperature lower than that of the body to be cooled into a cooling space in which a cooling medium is accommodated and bringing the cooling medium with the body.  
     CONSTITUTION: In a cooling space 3, a gas having a temperature lower than that of the body to be cooled is in a fluidized state by a circulating operation. The body 1 within the space 3 comes into smooth contact with a fine cooling medium 9 flowing by the gas. Further, the body 1 is cooled efficiently in a short period of time up to the vicinity of the ordinary temperature by means of the cooling medium 9 excellent in heat conductivity and amply containing low temperature heat from the gas. In this manner, the cooling medium 9 within the cooling space 3 does not stay on a ventilating floor 6 but flows by the cooled gas blown up from the floor and encircles the periphery of the body 1, and hence it is possible to cool the body 1 to a desired temperature.

IPC: F16J15/326
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To easily separate a sensor alone in a simple operation in a rotational speed-detecting apparatus. SOLUTION: A sensor 20 is mounted to a supporting annular body 40 in a manner of engaging an engagement element 22 of the sensor 20 with the supporting annular body 40, so that the sensor 20 is prevented from easily dropping. The engagement element 22 of the sensor 20 is not an elastic engagement element as in the prior art, but can be elastically deformed or broken by an external force. Therefore, in separating the sensor 20 from the supporting annular body 40, the external force is applied to the sensor 20 thereby elastically deforming or breaking the engagement element 22. The sensor 20 can be taken outside without resistance.

Title: Halogen battery
Inventor: FURUYA CHOICHI
IPC: H01M4/96
Filed: 1986-02-06
Abstract: PURPOSE:To quickly absorb and diffuse hydrogen gas evolved in a hydrophilic layer in an anode into a diffusion layer at the start of charge so as not to disturb the deposition of metal on the anode, and to increase bonding force of deposited metal, to increase charging rate and to increase the capacity by using a gas diffusion electrode in an anode. CONSTITUTION:A gas diffusion electrode 3 serving as an anode and an electrode 4 obtained by supporting a platinum group metal on a carbon felt, serving as a cathode, are arranged in an aqueous solution 2 comprising ZnCl2, KCl, and NaCl. During charge, the solution 2 penetrates in the hydrophilic part of a hydrophilic layer 7 in the gas diffusion electrode 3. Hydrogen gas evolved in the reaction is quickly absorbed in hydkrophobic part in the hydrophilic layer 7 and diffused in a gas diffusion layer 8, then exhausted outside. Zinc is deposited on the surface of the electrode 3, and zinc concentration in the solution 2 is gradually decreased, and after the completion of charge, ZnCl solution having low concentration is produced. The hydrogen gas evolved in the hydrophilic layer 7 is quickly absorbed and diffused into the gas diffusion layer 8 and the deposition of metal is not disturbed. Therefore, charging amount per unit time is increased, and charging time is shortened.

Abstract: PURPOSE:To improve the precision of judging voiced/voiceless in a speech while using a low-precision judging rule. CONSTITUTION:Feature parameters extracted from a frame-divided speech signal are decided by 1st and 2nd many-valued logical decision parts 2 and 3 according to their likelihoods. An inference part 4 infers whether the speech signal is voiced or voiceless by using the outputs of the 1st and 2nd many-valued decision parts 2 and 3 and a decision result feedback part 7. A variable hangover generation part 5 varies a hangover time according to the result of the inference part 4 and a binary decision part 6 judges voiced or voiceless finally.

Title: Heat treatment of silicon single crystal wafer
Inventor: HISATOMI TAKEHIRO
IPC: H01L21/324
Filed: 1999-02-02
Abstract: PROBLEM TO BE SOLVED: To suppress adhesion or slip by performing heat treatment in an atmosphere of inert gas, e.g. argon, admixed with a trace of oxygen and forming a thin oxide film on the required surface of a silicon single crystal wafer and a mounting jig made of silicon. SOLUTION: When heat treatment is carried out while admixing a trace of oxygen to an argon gas atmosphere, three regions 4, 5, 6 appear on the contact face side of a wafer because of extremely low oxygen flow rate. When the extremely low flow rate of oxygen admixed to argon gas is varied continuously or stepwise as the heat treating time elapses, a ring region 6 appearing on the interface of an oxide film forming region 4 and the remaining native oxide film region, i.e., an ungrown region 5, is shifted. Since sublimation reaction does not progress, generation of the region 6 can be reduced while preventing local adhesion and slip can be suppressed.
