IPC: C07C63/14
Filed: 1984-03-01
Abstract: PURPOSE:To obtain an aromatic carboxylic acid useful as a raw material for synthetic fibers and plastics, etc., by oxidizing an aromatic hydrocarbon having an alkyl group in the liquid phase by application of ultrasonic waves to make it possible to carry out the reaction at a higher rate and a lower temperature. CONSTITUTION:A mixed solution of a solvent and a catalyst is filled in a reactor 1 and heated with a heater 8, and an aromatic hydrocarbon having at least one alkyl group, e.g. p-xylene, or an oxidation intermediate thereof and a gas containing O2 are introduced thereinto when the temperature reaches the reaction temperature. Ultrasonic waves at >=10kHz are applied from an ultrasonic vibrator 10 mounted on an ultrasonic generator 11 to carry out the oxidation reaction in the liquid phase and give the aimed compound. Since the ultrasonic generator 11 is incapable of withstanding high temperatures, the generator 11 is preferably cooled to 100 deg.C or below by a cooler 9. EFFECT:Fine mixing not found in ordinary stirring can be carried out, and the reaction rate can be increased at low temperatures due to activation of molecules by cavitation effect.

Abstract: PROBLEM TO BE SOLVED: To uniformize turn around times by dynamically adjusting CPU allocation when a job is executed. SOLUTION: A means 15 executing a job as much as time given in time division executes one job dropped from a queue by a time division system. A means 16 adding execution time of this time to a corresponding execution time area executes one job by the time division system and subsequently, adds the time when the job is executed to an execution time area 23 corresponding to a queue 24 to which the job should belong. Processing 19 calculating the ratio of the execution time area compares values of the areas 23 corresponding to respective queues 24 and calculates a ratio. A means 20 allocating each CPU to each queue allocates each CPU to each queue 24 with a ratio being the same as a ratio calculated from the value of the area 23 corresponding to each queue 24.

Title: System for controlling assigned channel
Inventor: IEMURA TAKANARI
IPC: H04J3/00
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To improve the channel quality by using two output signals from a signal detector and a unique word detector so as to learn distribution of interference noise of each channel and using a channel with less interference with priority. SOLUTION: A transmission signal passes through only an extract device 134 of a channel 1 in a base station modem 130 and is detected by a signal detector 135. When the signal detector 135 detects the signal, it is demodulated by a demodulator 133 and a unique word detector 132 detects a unique word. An assignment channel detector 110 uses a counter to count number of times where no unique word is detected regardless of the detection of the signal by using output signals from the signal detector and the unique word detector. Then distribtution of interference noise of each channel is learned and the use of a channel with less interference with priority is controlled. Thus, the channel quality is improved.

IPC: C02F11/00
Filed: 1978-04-06
Abstract: PURPOSE: To enable to filtrate simply and to highly dehydrate sludge without spoiling improved effects by transferring sludge after passages and tanks have been filled with water, and recovering water after predetermined time is elapsed.  
     CONSTITUTION: Sludge is introduced into a freezing-and-melting tank 2 and processed by a heat-exchanger 1 by means of freezing-and-melting process, then characteristics of the sludge in its grain size and settling are changed. Succeedingly, a valve 9 is opened, a pump 8 is operated and a dehydrating tank 4 and other containers, into which the sludge is scheduled to be transferred, are filled with water before a discharge port 3 is opened and the sludge is transferred into them. Then the sludge having improved characteristics is transferred through water slowly and without being given shock. When the discharge port 3 is opened, sludge sinks immediately through water and is accumulated on a filtrating cloth belt 5 in the dehydrating tank 4. Under this state, the pump 8 is operated again and water is sent back into a water tank 10.

Title: Laser beam machining method
Inventor: NIIMI AKIHIKO
IPC: B23K26/00
Filed: 1985-03-01
Abstract: PURPOSE:To prevent the generation of blow hole inside welding zone by moving in the feeding direction of the body to be worked under vibrating the focus of converged laser beam in the plate thickness direction of the body to be worked. CONSTITUTION:A laser beam 10 is deflected vertically to the lower part by reflection mirror 6 and becomes a converged laser beam 11 by a condensing lens 8. In this case, the focus position is set to the position (a) coming in slightly under the lower part than the upper face of the bodies 1a, 1b to be worked. The converged laser beam 11 is irradiated on the bodies 1a, 1b to be worked with reciprocally moving the condensing lens 8 in the upper and lower directions by operating an agitator 9 on starting of welding. In this case, a working gas is fed as well from a feeding port 3 simultaneously with the vibration. The focus position (a) is moved further to the position in the lower direction (b) from the position coming slightly under from the upper face of the bodies 1a, 1b to be worked and returns to the original position (a). Namely due to the feeding motion in welding being combined in addition to the vertical movement of the focus position, the locus of the focus becomes in a saw edge shape 12. The weld without any defect is thus performed by giving a vibration stirring to a molten metal 13 and by expelling the bubbles, etc. of the inner part to the external part.
