Title: Hot water supplier
Inventor: UEDA TETSUYA
IPC: F24H1/24
Filed: 1986-12-25
Abstract: PURPOSE:To raise the heat exchange efficiency and improve the durability of a can body by providing the upper section of an inner cylinder with a fine corrugation which have a wavy cross section and the lower section of the inner cylinder with a rough corrugation the cross section of which is similar to said fine corrugation but larger. CONSTITUTION:When a combustion gas passes between an inner cylinder 2 and a baffle 7, a turbulent gas flow occurs, but because the cross-sectional shape of the inner cylinder is wavy and the tip end of a baffle plate 9 is located in a concave section 14 of the inner cylinder 2, the extent of turbulence at this section is larger so that it is possible to raise the heat exchange efficiency between the cumbustion gas and the water in a water storage section 4. Further, because a fine corrugation 12 is provided at the upper section of the inner cylinder 2, the effect of the turbulent flow is further improved at the upper section and it is possible to obtain a higher heat exchange efficiency. Further, because at the lower section of the inner cylinder 2 where the temperature is highest a rough corrugation 13 is provided, the effect of thermal expansion absorption at this section is further improved, and because it is possible to make little difference of thermal expansion at the inner cylinder 2 and the outer cylinder 3, the development of thermal stresses in the inner cylinder 2 and outer cylinder 3 can be prevented and the durability of the can body 1 can be raised.

Title: Cadmium electrode for alkaline storage battery and its manufacture
Inventor: IWASAKI KAZUTAKA
IPC: H01M10/52
Filed: 1986-12-25
Abstract: PURPOSE:To obtain a cadmium electrode to secure a good electron conductivity and to have almost no cycle deterioration in the gas absorption capacity, by using an active carbon fiber processed with fluorine contained resin. CONSTITUTION:This cadmium electrode is composed of an active substance layer which consists of an active carbon fiber with fluorine contained resin attached over the surface, and an active substance which consists of mainly cadmium oxide or cadmium hydroxide and a conductive core material on whose surface the active substance layer is formed. Since the water-repelling property of the fluorine contained resin is given to the surface of the active carbon fiber in such a composition, the hydrophobic property of the active carbon fiber is improved, and wetting to the alkaline solution can be controlled adequately. Moreover, since the surface of the active carbon fiber is protected from covering with the alkaline solution owing to the repeated charge and discharge, its catalystic property can be maintained for long. Cousequently, the gas absorption capacity of the cadmium electrode in which the active substance layer of dispersed active carbon fiber is formed is not deteriorated even though the charge and discharge cycle is repeated, and the original favorable condition can be maintained for a long period of time.

Title: Production of material for insoluble anode
Inventor: NOBEYOSHI RYOICHI
IPC: C23C10/28
Filed: 1987-12-09
Abstract: PURPOSE:To inhibit the formation of a passive film during the supply of electric current by coating a Ti base material with Ni and heat treating the coated material. CONSTITUTION:A Ti base material is coated with Ni and the coated material is heat treated to form a Ti-Ni alloy layer by the thermal diffusion of the formed Ni layer. In order to convert all the Ni layer on the surface of the base material into an intermetallic compd., it is necessary to decide the heat treatment temp. and time in accordance with the thickness of the Ni layer. Thus, a material for an insoluble anode usable for electrowinning or electroplating can easily be produced. A passive film is not formed on the insoluble anode made of the material over a long period and the anode ensures low stable bath voltage, superior current efficiency and energy efficiency.

Title: Analytic optical system for centrifugal separator
Inventor: KATAOKA KEIJI
IPC: G01N9/30
Filed: 1990-11-16
Abstract: PURPOSE:To measure the transmission light intensity on the whole surface of a sample by diminution-focusing a radiation slit from which the spectroanalyzed light is radiated, forming a light spot for irradiating only the fine region of the sample and shifting the light spot. CONSTITUTION:The light radiated from a Xe lamp 1 is introduced into an incidence side slit 4 by a spherical surface mirror 2, and a concaved surface grating 3 takes out the light having a variety of wave length outside a radiation side slit 4. A lens 5 diminishes the light intensity on the slit 4 and focuses an image on a sample 10. Since each equal centrifugal force acts at the place of a sample having different revolution angular direction, the sample has no spatial distribution, and the need of the high resolving power in measurement is obviated. When a mirror 6 is shifted in the direction of the arrow 14, the whole surface of the sample 10 can be measured. The light which passes through the sample is condensed by a spherical surface mirror 11, and detected by a light detector 12.

Patent JP-H02157958-A (JP)
Title: Semiconductor device
Inventor: ODAWARA HIDEYUKI
IPC: G06F13/12
Filed: 1988-12-09
Abstract: PURPOSE:To obtain general usefulness in a semiconductor device with the small number of terminals by providing a register and a circuit to switch synchronously or asynchronously the input / output of data to an external part in the internal part of the semi-conductor device equipped with an I/O port. CONSTITUTION:When a switching register 4 shows an asynchronous system, the data is outputted with external asynchronization since the data of a data register 1 is passed through a multiplexer 5 as it is and outputted to the external part. Next, when the switching register 4 shows a synchronous system, the data of the data register 1 goes into a latch 2 for external synchronization. The data goes up to the multiplexer 5 by a signal from an external synchronous signal input line 3 and since the switching register 4 selects the synchronous system, the value of the data register is matched with the signal of the external synchronous signal input line 3 and outputted. In the case of an input, operation is samely executed as the above mentioned case of the output as well. Thus, even one I/O port can be used as the external synchronous system and external asynchronous system.

Title: Pressure roll device
Inventor: OGURA MITSURU

Filed: 1988-12-09
Abstract: PURPOSE:To reduce the cost of the device and, at the same time, to prevent the device from getting larger in size by supply the driving system of pressure rolls and driving system for a pressure releasing mechanism from the same sequence. CONSTITUTION:An upper and lower holders 1 and 2 are pushed in the press- contacting direction by means of a pressurizing mechanism 4 when the narrow- width side of an eccentric cam 22 is brought into contact with the upper holder 1 and the cam 22 brings up the holder 1 against the pushing force of the mechanism 4 when the wide-width side is brought into contact with the holder 1. Thus the holders 1 and 2 supporting pressure rolls are pushed in the press- contacting direction by means of the mechanism 4 and objects to be pressed are pressed when a pressing process is performed for destroying microcapsules, etc. When the pressure is released, a driving force is transmitted to a pressure releasing mechanism including the cam 22 and the cam 22 is rotated. As a result, the holders 1 and 2 are pushed in the direction opposite to the press- contacting direction and the pressure rolls are released from the pressing state. Therefore, this pressure roll device itself can be reduced in size and cost.

IPC: G11C16/02
Filed: 1993-12-14
Abstract: PURPOSE:To obtain a non-volatile semiconductor memory capable of detecting or relieving a memory cell of an over erasing state. CONSTITUTION:When a operational mode signal OEV obtained from a command decoder 13' indicates an over erasing verifying mode, a negative voltage generating circuit 31 generates negative voltage.

IPC: F02G5/02
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To provide a thawing means to than the condensed water generated by an exhaust heat exchanger and frozen or nearly frozen in a drain. SOLUTION: The condensed water separated from exhaust emission at a muffler 31 is discharged outside through an exhaust water trap including a joint 34.
