Title: Water treatment method
Inventor: ASHITANI TOSHIO
IPC: B01D21/01
Filed: 1994-06-13
Abstract: PURPOSE:To provide an economical water treatment method which has a high cutback ratio of trihalomethane generation capacity and produces only a small amount of waste sludge by adding an Al-type coagulant and activated carbon into water. CONSTITUTION:An Al-type coagulant (e.g. polyaluminum chloride) expressed by the formula and activated carbon are added into water. Formula: Al2(OH)xXy(SO4)3 [X is monovalent anion (e.g. Cl), x+y+2z=6.3<=x<=4.8, and 0.565>=z>=0.392 when 3<=x<=3.9, 0.565+11/3 (0.65-X/6)>=z>=0.1+2/3(0.65-X/6) when 3.9<X<=4.8] Besides, the ratio (wt. ratio) of the Al type coagulant to activated carbon added to water is Al-type coagulant (in terms of Al2O3)/activated carbon (in terms of carbon) 1-0.05. By this simple method, a trihalomethane generation capacity, the amount of produced waste sludge, and a water treatment cost can be reduced as compared with a conventional one.

Title: Dewaxing method for precision casting mold
Inventor: ASHIDA SUNAO
IPC: B22C9/04
Filed: 1986-06-04
Abstract: PURPOSE:To discharge molten wax and to prevent the cracking of casting molds by applying microwave induction heating to the casting molds consisting of a coating material kneaded with an electrolytic material thereby melting the surfaces of wax patterns without heating the wax patterns. CONSTITUTION:Graphite powder or electrolytic material such as tri-iron tetroxide or cupric oxide is added to the coating material and the mixture is kneaded. The wax patterns 2 are immersed into the slurry of such coating material 3 to coat the same. The casting molds 1 constituted by forming the coating layers on the wax patterns 2 are successively imposed on receiving trays 24 on a conveyor 21 and are successively fed into an induction heating chamber 10. Microwave oscillators 12 are successively triggered to oscillate from the inlet, by which the coating layers are quickly heated and the contact surfaces between the surface parts of the wax patterns 2 and the inside surface parts of the coating layers are melted. The molten wax is discharged onto the trays 24 but the inside of the wax patterns 2 is hardly heated; therefore, the wax does not melt. The molds are then conveyed into the hot wind chamber 14 where the molds are heated by hot wind. The remaining wax is thoroughly melted in the hot wind chamber 14 and is discharged onto the trays 24. The molds are ejected from the chamber 14 by the conveyor 21.

Title: Tracing method for system operation in on-line service
Inventor: SAKATA YUTAKA
IPC: G06F11/28
Filed: 1990-05-23
Abstract: PURPOSE:To facilitate the investigation of the cause of failure and its repair by stacking trace information showing trace points are passed in a main storage when a CPU executes instructions at the trace points set previously in an OS, a package, and a transaction program during service operation. CONSTITUTION:The trace points are set before and behind a program 3 where the presence of the cause of failure is estimated and when the CPU passes the trace points in on-line processing, information on the passage is stacked in a trace point storage area on the main storage. If system failure occurs and the system is shut down, main storage dump information is gathered on a magnetic MT by the operation rule of the system. Therefore, the operation state of the program 3 right before the system failure occurs is made clear with the trace point storage area in the dump information of the main storage. Consequently, the investigation of the cause of the failure and its repair are facilitated.

Title: Simple oxygen cylinder
Inventor: MIZUMAKI KATSUMI
IPC: F17C11/00
Filed: 1984-06-26
Abstract: PURPOSE:To accommodate the oxygen as much as possible under a pressure less than a prescribed value by using a common can on the market and by introducing oxygen or oxygen-rich air under a pressure lower than 10kg/cm<2>G at 20 deg.C into a container filled with activated carbon. CONSTITUTION:An air-sol can filled with activated carbon is used, and filled with oxygen gas or oxygen-rich air under pressure. For example, granular activated carbon is introduced into an AE420 can having an inside capacity of 420ml, and oxygen is introduced up to a pressure of 10kg/cm<2>G at 20 deg.C. Then, oxygen is discharged by opening a valve, and then 10.5l oxygen is obtained. In other words, oxygen in 2.5 times per space volume can be accommodated. When the oxygen having a purity close to 100% is used, it reacts with activated carbon particularly in the preservation at high temperature, and CO2 or CO gas is formed.

Title: Method forsurface finishing with to form grained three-dimensional pattern of wood grain
Inventor: AONO HIDEO
IPC: B44F9/02
Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a three-dimensional expression of high quality and form a pattern equivalent to a natural grain by providing a coating material layer through applying a coating material to the surface to be finished with the help of a brush or a spatula and sliding the coating material layer while kneading the coating material with a scraping spatula. SOLUTION: A coating material obtained by mixing and stirring about 100 parts of a commercial-grade aqueous enamel and about 60 parts of a commercial-grade polishing powder in terms of weight ratio is uniformly applied to a lauan plywood 1 with a brush to form a coating material layer 2. The coating material layer 2 is immediately caused to slide while the coating material is kneaded using a scraping spatula. In this case, a face below grooves formed on the curved face of the scraping spatula comes into contact with a face to be finished 1. Further, the coating material layer 2 is scraped off at the contact part and the coating material layer 2 formed on the part in which the grooves pass is left unscraped and consequently forms a three-dimensional pattern with wood grain.  The scraping spatuls has grooves formed on the curved face of a curved material on the lower surface of a handle. The shape of the grooves formed on the curved face can be changed. The width of the grooves can be set uniformly or non-uniformly, or both uniform and non-uniform widths can be freely combined.

Abstract: PURPOSE:To permit the washing of rice without using water and improve the measurement precision of water by installing a rice washing part for removing the rice bran and detecting the water level of a water supply part and determining the proper quantity of water and applying the correction according to the room temperature onto the detected water level. CONSTITUTION:The rice discharge part 9 of a rice chest 8 measures rice by each prescribed quantity by the control signal in a control part 7. Then, a rice washing brush 10 is provided by the drive of a rice washing motor 11 in the rice washing part 2, and the rice bran, etc., adhering on the surface are removed between a polishing body 12. At the same time, a transfer fan 19 in a rice transport part 3 is driven, and the removed rice bran is recovered into a rice bran container 18 through an air discharge hole 16. The water level of the water surface of a water tank 28 in a water supply part 4 is measured by detecting the variation of the static electricity between a pair of sensor electrodes 29a and 29b installed oppositely to the side wall of a water tank 28. Further, the room temperature correction and the correction according to the water temperature in a water level correcting part 6 are carried out by using a temperature sensor such as thermistor. Also the error in the water quantity according to the variation of water temperature, room temperature, and water quality can be removed, and since a rice washing means does not use water, the error due to the adsorption of water onto the rice can be eliminated.
