Title: Removing device for scale in bundle of tube for heat exchanger or the like
Inventor: IMAI MITSUO
IPC: F28G1/12
Filed: 1984-02-29
Abstract: PURPOSE:To permit to remove scale thoroughly by a method wherein a gas sealing device is provided and sponge balls are dehydrated to circulate them through the inside of the bundle of tube. CONSTITUTION:When a chamber 19 is filled with gas through a gas sealing pipe 20 and a cage unit 17 is rotated, processing water is dehydrated by a centrifugal force and the gas is sealed into the inside of the ball 15. Next, the processing liquid is introduced into the chamber 19 by a pump 23 to float up the sponge balls 15 and flow them through a transfer tube 6. The sponge balls 15 pass through the bundle of tubes of the heat exchanger 2 together with the processing liquid, remove the scale, separated from the processing liquid in a strainer 9, return into the chamber 19 through a return pipe 25 and thus they are recirculated. At the initial period of circulation, the specific gravity of the ball is light due to the sealing of the gas and the ball passes through the heat transfer tube at the upper side of the bundle of tube, however, the gas is removed during repeating the circulation of the ball, the specific gravity of the ball becomes heavier and the ball passes through the heat transfer tubes at the lower side of the bundle of tube. Accordingly, the sponge balls pass all the tubes at the upper and lower parts of the bundle of tube and the scale in the tubes may be removed in all stages of the tubes.

Title: Power supply control system
Inventor: IDO TSUNEO
IPC: G06F1/00
Filed: 1985-02-27
Abstract: PURPOSE:To switch on a power supply when a service interruption is recovered by storing in a latch means a fact that the power supply was not switched on at a due time point in a power failure. CONSTITUTION:A time counter 4 counts the time by the clock given from an oscillator 5. When a comparator 6 detects in a power failure that coincidence is secured between the count value of the counter 4 and the value of a comparison register 3, a power supply ON latch 11 is set and the count value of the counter 4 is replaced and set at a level different from the value of the register 3. Thus a primary power supply 7 can be switched on according to the information on the latch 11 after the power failure is recovered since the information on the power supply ON remains at the latch 11 although no output of the comparator is available.

Title: Method for preventing solidification of salt
Inventor: ITO HIROSHI
IPC: C01D3/26
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent a salt from being solidified while maintaining fluidity of the salt without causing any cloudiness when the salt is dissolved in water by coating the surfaces of salt crystals with trehalose. SOLUTION: Trehalose represented by the formula is dissolved into water to obtain a trehalose aqueous solution, the trehalose aqueous solution is added to the salt consisting essentially of sodium chloride such as common salt with a sprayer or the like, and they are mixed. The resulting mixture is dried with a hot-air dryer to coat the surfaces of salt crystals with trehalose.  In the method, trehalose is used in an amount sufficient to provide a >=0.5 wt.% ratio of trehalose to the salt and a highly concentrated trehalose aqueous solution is desired when added to the salt, and also, since trehalose hardly causes moisture adsorption or release in an environmental condition of a <=95% relative humidity, by coating the surfaces of salt crystals with trehalose, moisture adsorption or release on or from the surfaces of salt crystals can be inhibited and the salt is prevented from being solidified. Accordingly trehalose is effectively used for salt which has a high sodium chloride content and a low water content and is liable to be solidified. Further, trehalose is an edible glucide and can appropriately be applied to salt for food such as table salt.

Title: Fuel controlling method of engine
Inventor: UMEHARA JIYUN
IPC: F02D41/06
Filed: 1984-02-27
Abstract: PURPOSE:To secure an engine's favorable starting characteristic all the time, by making fuel spout from an injection valve at a time when off-on time in a power switch is long but making it so as not to spout from the injection valve when the said time is short the other way. CONSTITUTION:Off-on time in a power switch 4 is compared with the setting time corresponding to an engine characteristic at a step 1. When the off-on time is longer than the setting time, an injection valve 1 is driven in time of the power switch 4 being on, making it spout fuel to an engine at a step 3. When the off-on time is shorter than the setting time, the fuel is made not to spout out of the injection valve 1 any more. Thus, an air-fuel ratio in time of engine starting is adapted to the engine characteristic whereby a favorable engine characteristic is securable all the time.

Title: Transversal filter
Inventor: TAJIMA KOUJIROU
IPC: H03H9/42
Filed: 1983-03-07
Abstract: PURPOSE:To obtain a miniature and high-speed transversal filter by attaining the equivalent working of a delay line of the transversal filter in response to the delay time difference of surface acoustic wave element. CONSTITUTION:An end of each of surface acoustic wave elements 7a-7e is connected to an input terminal 1 and receives the supply of input signal. Transmission lines 8a-8e of elements 7a-7e increase successively and every unit time DELTAtau, and therefore the time when the input signal is delivered to the other end of each surface acoustic wave element is different by the delay time difference DELTAtau among those elements. Thus the lines 8b-8e excluding the shortest line 8a have the working equivalent to a case where the delay lines of delay time DELTAtau are connected in series and the output is delivered from the juncture. The delay time of the line 8a is set larger than DELTAtau. These delayed outputs are synthesized by a synthesizer 4 via a weighting device or vector modulators 3a-3e and sent to an output terminal 5.

Abstract: PURPOSE:To inhibit the generation of a crystal defect and to make it possible to form precisely an SiO2 layer of a prescribed film thickness and a thin Si layer by a method wherein a first-time oxygen ion implantation is performed in an Si substrate and thereafter, acceleration energy is made lower than that among the first-time ion implantation conditions, a second-time oxygen ion implantation is performed and a heat treatment is performed. CONSTITUTION:A first-time oxygen ion (O<+>) implantation is first performed in an Si substrate 8 on prescribed ion implantation conditions while the back surface of the substrate 8 is heated. Then, an annealing is performed in an Ar-containing atmosphere and an Si layer 11 made to recover from implantation damage is obtained on an SiO2 layer 10 along with the layer 10 by an oxidation of oxygen ions 9 and Si. Then, an acceleration energy is made lower than that among the first-time ion implantation conditions and a second-time oxygen ion (O<+>) implantation is performed in the same way as the way at the time of the first-time oxygen ion (O<+>) implantation. When an annealing is performed, a new SiO2 layer is grown on the layer 10 and an Si layer 14 of a thin film thickness is formed along with an SiO2 layer 13 of a thick film thickness. Thereby, the implantation damage to the substrate is reduced, the generation of a crystal defect is inhibited and the SiO2 layer of a prescribed film thickness and the thin Si layer can be precisely formed.
