Patent JP-S6158317-A (JP)
Title: Internal bus circuit
Inventor: IWATA TOSHIYOSHI
IPC: H03K19/096
Filed: 1984-08-30
Abstract: PURPOSE:To prevent influence of the change in bus signal to other circuits, suh as register cell, etc., when the operating speed is increased, by providing a means which receives bus signals, detects and amplifies the change in bus signal, and feeds back the amplified change to an internal bus. CONSTITUTION:An internal bus 21 is precharged when a precharging transistor 27 is conducted by a precharge signal PR1. When a low level is transferred at the transferring cycle of data thereafter, discharging takes place by a discharging transistor in a register 22. When the level of the internal bus 21 becomes lower than the low-level discriminating level of a comparator 24, a pull-down transistor 26 is conducted through an NOR gate 25 and the discharging speed of the internal bus 21 is increased. Therefore, no influences are given to other circuits, such as register cell, etc., even when the operating speed is increased.

Title: Solvent extraction method
Inventor: TAKAHASHI NOBUO
IPC: C22B3/00
Filed: 1986-07-31
Abstract: PURPOSE:To simply extract metal ions from an aq. soln. in an efficient and stable manner by bringing an org. acidic extracting reagent diluted with a diluent into contact with the aq. soln. in the presence of an amine which is soluble in the extracting reagent and the diluent but is slightly soluble in water. CONSTITUTION:When metal ions are extracted from an aq. soln. with an org. acidic extracting reagent such as acidic phosphoric ester or carboxylic acid diluted with a diluent such as kerosene, an amine which is soluble in the extracting reagent and the diluent but is slightly soluble in water is added to the org. phase for solvent extraction. A tert. amine such as tri-n-octylamine is suitable for use as the amine and the amine is preferably added by an amount (mol) nearly equal to the amount of the extracting reagent. Thus, pH control is made unnecessary and the metal ions are extracted in a stable and efficient manner. The metal ions in the org. phase are then recovered by back extraction and the extracting reagent is regenerated. Alkali is added to the org. phase contg. a remaining amine salt to regenerate the amine and this amine is utilized again.

Thereafter, when a working fluid is supplied into a lower chamber of a closing cylinder 13, the movable platen 12 is pressed downwardly to close the molds. There is nothing above the movable platen 12, and therefore this reduces the overall height thereof.  When the movable platen 12 is flucturated, since the tie bar 3 is guided with a great guide width by a shaft hole 2a of a fixed platen 2 and a guide hole 1b of an upper frame, smooth fluctuating movements can be provided.

Title: Floating impeller utilizing hood
Inventor: INABA HIROYA
IPC: A63H27/00
Filed: 1983-09-29
Abstract: PURPOSE:To enhance the floating efficiency of an impeller, by providing such an arrangement that air is introduced into a parachute shape hood by means of the impeller, and is then directed downward to obtain bouyancy. CONSTITUTION:The ambient air is introduced below a hood 1 formed in a parachute shape. An impeller 3 introduces the ambient air into the hood when it is rotated. The rotation of the impeller 3 causes the air sucked from a suction port 2 to be scattered around under centrifugal forse so that air flow takes place horizontally. The direction of this air flow is changed downward by means of the hood 1 so that hood 1 is exerted with an upward impluse corresponding to a variation in the momentum of the air flow, thereby bouyancy may be obtained.

Abstract: PROBLEM TO BE SOLVED: To obtain a stable emulsified cosmetic containing a specific polyglycerol fatty acid ester, a powdery material and an oil agent, good in touch, excellent in water resistance, and high in a UV light-protecting effect. SOLUTION: This emulsified cosmetic comprises the following components as active components: (A) at least 0.2wt.% of a polyglycerol fatty acid ester which is the ester of polyglycerol having an average polymerization degree of >=4 with a fatty acid, (B) 2-20wt.% of a powdery material, (C) 5-50wt.% of an oil agent, and (D) water. The emulsified cosmetic of O/W type emulsion is prepared by mixing and heating the components (A), (B) and (C), treating the mixture with a homogenizing mixer, heating and mixing the homogenized mixture with one or more of other oily phase components, adding the mixture to an aqueous phase component, and subsequently stirring the mixture.  When an inorganic powdery material, especially, titanium dioxide particles, etc., is added as the powdery material, the employment of the polyglycerol fatty acid ester enables to homogeneously and stably disperse the powdery material without causing the aggregation of the powdery material. When a general surfactant is used, the dispersion of the inorganic powdery material is unstable.

Abstract: PURPOSE:To increase the air heating capacity of a circulator, by providing an open/close valve to a circulating pipe which connects an open type tank to a boiler drum, as well as to connect the open type tank, the boiler drum, and a convector by the circulating pipe, and by locating a cylindrical lower tank surrounding the boiler drum, while by connecting the lower tank to the open type tank. CONSTITUTION:The steam produced in a boiler drum 2 applies pressure upon the water level in the boiler drum 2 to feed hot water out to a convector 3 when an open/close valve 5 is closed. The water is cooled in the convector 3, and is returned to the open type tank 1, mixed with the hot water in the open type tank 1, while the boiler 2 is heated by a burner 7. When the hot water in the boiler drum 2 is fed out to the convector 3, the open/close valve 5 is opened by a signal from a changing switch 9, and the hot water in the open type tank 1 is fed into the boiler drum 2 as the water level in the tank 1 is higher than that of a boiler drum 2. When the drum 2 is made full with hot water, the open/close valve 5 is closed, and again the steam produced in the boiler drum 2 feeds the hot water out to the convector 3 from the drum 2, and circulation cycles are continued in such a manner.
