Title: Treatment of waste water
Inventor: TODA TAKASHI
IPC: C02F1/72
Filed: 1985-02-25
Abstract: PURPOSE:To treat effectively high-COD concn. waste water by adopting the Fenton oxidation as the pretreatment wherein the addition of hydrogen peroxide and an iron salt is purposely reduced and using a simple method wherein a flocculation and separation vessel, sludge treating equipment, etc., can be dispensed with. CONSTITUTION:Waste water contg. org. matter is oxidized in the presence of hydrogen peroxide and a ferrous salt and then treated with activated sludge. In this waste water treatment, hydrogen peroxide less than the COD and Mn to be removed in waste water and a ferrous salt, 1/70-1/7 of the amt. of COD and Mn to be removed (expressed in terms of ferrous ions), are added to waste water. Waste water is then regulated at 1.0-2.0pH, oxidized at 5-95 deg.C for 3-8hr, neutralized with an alkali and then treated with activated sludge. Namely, high-COD concn. waste water contg. org. matter can be treated even by the addition of a small amt. of hydrogen peroxide and a ferrous salt. Since the sludge of iron salts is not generated during the treatment, a flocculation and separation vessel, sludge treating equipment, etc., can be dispensed with.

Abstract: PURPOSE:To obtain an excellent photomagnetic memory storage having a large photomagnetic effect and whose Curie temp. is higher than that of conventional Tm compd. by specifying the composition of an alloy having an easy magnetiza tion axis vertical to the surface of a film. CONSTITUTION:A compd. consisting essentially of a rare earth element other than Tm in place of the conventionally used Tm and added with an element of the VIII A-VI A group with a metalloid element as the center is prepared. Consequently, the Curie temp. Tc of the compd. is made higher than that of the Tm compd. and the Kerr angle of rotation is made the same as or more than that of the Tm compd. The magnetic thin film of the compd. is generally polycrystalline and has a strong tendency to form an easy magnetization axis in the in-plane direction, however the film can also be made amorphous by adjusting the preparation conditions and composition and hence a vertical mag netic film can be sufficiently formed. The compd. is used as a vertical magnetic film and as a high-density photomagnetic recording medium. When an amor phous film is used, the noise of the reading signal due to the grain boundary, etc., is further reduced and hence an excellent medium can be obtained.

Title: Vapor growth method for compound semiconductor crystal
Inventor: SHIMAZU MITSURU
IPC: H01L21/205
Filed: 1990-02-20
Abstract: PURPOSE:To control the quantity of doping with carbon favorably by changing growth pressure, using an organic metal compound as group V material. CONSTITUTION:In the organ metal vapor growth for a III-V compound semiconductor, the growth pressure is changed using an organic metal compound as group V material. What is more, it is to be desired that the growth pressure should be controlled within the range of 1-40Torrs, and that the growth temperature should be 625 deg.C or less. Moreover, the control method for growth pressure is not especially limited, but, for example, a method of arranging a valve between the rotary pump for evacuating the inside of a reaction pipe and the reaction pipe so as to change the degree of opening, or a method of increasing or decreasing the flow of carrier gas with the degree of opening of the valve maintained constant so as to control the pressure, can be adopted. Hereby, without changing the growth temperature, the quantity of doping with carbon can be changed easily in a short time.

IPC: F02D19/08
Filed: 1983-03-09
Abstract: PURPOSE:To enhance the starting characteristics of engine as well as that of a car using alcoholic fuel and thereby prevent occurrence of engine stops by setting the incremental rate of the fuel injection amount separately for the idling period and non-idling period, while the engine temp. is low. CONSTITUTION:In fuel injection control of a car using alcohol as main fuel, the engine coolant temp. Tw is sensed (64), and if the sensed value is below a specific value (for ex. 10 deg.C), it shall be judged (68) whether the engine is in idling or not. It is judged as under idling if the automatic speed changer is set in the stop range by a neutral switch, and under non-idling period if in the running range, and then the incremental rate is calculated (70, 72) from the characteristic curves W1, W2 for the idling and non-idling periods, respectively. On the basis thereof the final amount of fuel injection Qf is calculated (74). Accordingly the incremental rate during non-idling period is large to ensure prevention of engine stop at the time of starting.
