Title: Switching regulator
Inventor: NEGORO OSAMU
IPC: H02J9/06
Filed: 1989-01-21
Abstract: PURPOSE:To improve efficiency by a method wherein a circuit for switching DC output, produced by rectifying and smoothing AC input, and a switching circuit for switching the output of a backup battery are provided separately to use a battery circuit when an input AC voltage is reduced to a value lower than a predetermined value. CONSTITUTION:A DC voltage, obtained by rectifying and smoothing an AC input through a rectifying and smoothing circuit 1, is interrupted by a switching transistor STrQ1 to input it into a transformer TA and AC voltage, generated in the secondary winding NA2 of the transformer TA, is rectified by a rectifier D1 and smoothed by a capacitor C to impress a DC voltage on a load 5. The AC voltage, generated in the secondary winding NA1, is rectified by the rectifier D1 to charge a battery 3. A voltage monitoring unit 6 monitors the AC input and a gate G1 is put ON but the gate G2 is put OFF usually. When the voltage of the AC input is reduced to a valne lower than a predetermined value, the gate G1 is put OFF and the gate G2 is put ON to energize the STrQ2 to effect switching and supply an AC power to the load 5 through the transformer TB and a diode D4. An AC load voltage is compared with a reference voltage and a difference therebetween is amplified by an error amplifier A to control the STrQ1, STrQ2 by a controller OR through a photocoupler PC.

Abstract: PURPOSE: To reduce the cost of a container for metallic hydride for occluding hydrogen by activating the metallic hydride in an activating container, forming a pseudo-oxide film on the surface, and packing the resulting metallic hydride into a heat exchanger.  
     CONSTITUTION: Metallic particles 1 of TiFe or the like for storing hydrogen are put in an activating container 4, and by feeding gaseous hydrogen CH 2 , metallic hydride is formed by activation. An inert gas GN 2  such as nitrogen contg. a very small amount of gaseous oxygen GO 2  is then introduced to form a thin pseudo-oxide film on the surface of the metallic hydride. This metallic hydride is taken out of the container 4 and packed into a practical heat exchanger 2. The exchanger 2 requires only strength and quality corresponding to temp. and pressure during use, and a conventional heat and pressure resistant material is made unnecessary. When hydrogen is generated, the exchanger 2 is heated with an external heat source 5 such as solar heat, and desorbed gaseous hydrogen is stored in a hydrogen vessel 8.

Title: Atm connection reception controller
Inventor: SAITO HIROSHI
IPC: H04Q3/00
Filed: 1994-02-08
Abstract: PURPOSE:To economize the controller by assuming an arrival cell number distribution and a cell arrival process in advance so as to reduce required data quantity to be stored and quantity of arithmetic operation. CONSTITUTION:An arrival cell number for each unit time length T obtained by a cell number counter 51 and a threshold value K in a threshold value storage device 53 are compared by a comparator 52, and a rate M in excess of the value K is stored in a storage device 54. On the other hand, an average arrival cell number A for each time T is calculated and stored in a storage device. Upon the receipt of a connection request from a terminal equipment and a notice of a peak value R and an average value H, a maximum scheduled arrival cell number TART and an average scheduled arrival cell number J=HT are obtained and they are stored respectively to devices 57, 56. A device 58 receives the numbers J, I, M, A and estimates a cell abort rate through a prescribed arithmetic operation and provides an output to a comparator 59. In this case, the arrival cell number distribution is assumed to take an exponential distribution and the data quantity for arithmetic operation is reduced by using the number M to simplify the arithmetic operation. The cell abort estimate value is compared with a threshold value of a device 60 by a comparator 59 and when the former is smaller than the latter, the abort rate is accepted.

Title: Operation of membrane separator
Inventor: KAMIMURA KEIJI
IPC: B01D63/10
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To decrease the frequency of normal backwashings, to shorten the time to stop the collection of permeated water due to backwashing and to increase the working efficiency by applying a simple backwashing to supply gas on the permeated water side for an extremely short time while supplying water during the filtration stage, stopping the supply of raw water and supplying a gas. SOLUTION: When a spiral membrane module is backwashed, if a gas pressure is exerted on the permeated water passage in a bag-shaped membrane 10, the permeated water remaining in the membrane 10 flows into a raw water passage between the membranes 10, and water backwashing (a simple backwashing) is conducted. As a gas is successively supplied, the amt. of the remaining permeated water is decreased, and a mixture of the permeated water and gas flows backward, and gas-liq. mixture backwashing (normal backwashing) is performed. The pressure drop of the membrane is slightly decreased by the simple backwashing. Accordingly, by frequently applying 5-25 sec simple backwashing during the filtration stage between the 0.5-5 min normal backwashings, the pressure drop of the membrane is kept low for a long time, and the frequency of normal backwashings can be decreased.
