Title: Manufacture of organic electrolyte battery
Inventor: SADAMURA AKIRA
IPC: H01M4/08
Filed: 1985-04-18
Abstract: PURPOSE:To effectively remove moisture contained in positive mix by a short time treatment by drying a positive mix mainly comprising manganese dioxide with far infrared radiation. CONSTITUTION:The inside wall of a far infrared radiation furnace is lined with an aluminum foil except for a far infrared radiation heater. The heater is connected to a transformer 8 to control the temperature in the furnace. A positive mix 5 obtained by molding the mixture of manganese dioxide, carbon, and a fluorine resin binder is placed on a metal plate 9 made by stainless steel net. When a power source is turned on, far infrared radiation form the heater 7 is directly irradiated to the mix 5 and reflected randomly by the aluminum foil. Thereby, the positive mix 5 is irradiated from all directions, and its temperature is quickly increased to a desired value.

IPC: F28F19/00
Filed: 1985-04-18
Abstract: PURPOSE:To lengthen the operating time of the heat exchanger during frosting and improve the heat transfer performance thee of by a method wherein protrusions and recesses are formed alternately at the air inflow end of a fin so that the phases of recess and protrusion of neighboring fins are different and the heights in the air inflow direction of the recess and protrusion or the length in the direction of stage of the tube are different while such fins are laminated with intervals so as to form the group of fins and the group of tubes, through which a refrigerant is flowed, are attached to the group of fins. CONSTITUTION:Respective fins are provided with recesses 17 and protrusions 18 alternately in the direction of the stage of heat transfer tubes at the air inflow ends of respective fins 14, 15 fitted to the group 11 of the tubes vertically with a predetermined interval. In this case, the length (l') between the protrusions 16' in the direction of stages of the tubes is much smaller than the length (l) between protrusions provided on the fin 14. However, the heights (h), (h') between protrusions 16, 16' in the direction of airflow and the lengths from the air outflow end to the bottoms of the recesses 17, 17' are the same. Accordingly, the length of the leading edge of the fin is increased remarkably in the whole of the heat exchanger and the distance between fins at the inflow end of the air becomes two times larger than the same between fins at a place except the inflow end. According to this constitution, the operation time until defrosting may be lengthened.

CONSTITUTION:A card base material 3 is formed by laminating a surface sheet 1 having a piercing hole 41 having a size the same to that of an IC module provided thereto at the position of an IC module receiving hole to a back sheet 2. Next, the circumference of the IC module receiving hole 4 of this card base material 3 is bonded and integrated by ultrasonic waves or high frequency waves. Therefore, the inflow of an adhesive between the laminated sheets or the deformation of the IC module receiving hole is not generated. Next, an IC module 6 is inserted in the IC module receiving hole 4 in which an adhesive 5 is injected and pressed to form an IC card substrate. Subsequently, the IC card substrate is heated and pressed using two ferromagnetic plates 8 having mirror surfaces to obtain an IC card 7. The difference in level such as a projection or depression generated on the surfaces of the card base material and IC module is eliminated by heating and pressing.

Title: Residual fuel display apparatus for vehicle
Inventor: HAMADA MASAHIRO
IPC: G01F23/00
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To make the display of a residual fuel accurate by providing a function for deciding the display value of residual fuel just after turning on of an ignition(IGN) and a processing function for quickening the response ability of a display so as to follow the variation of an oil feed quantity in the case of feeding the oil by turning on IGN. SOLUTION: IGN.SW1a, a residual fuel detecter 1b and a car speed detecter 1c are connected to a controller 1 consisting of a microprocessor or the like, and the residual fuel quantity is displayed by analog or digital quantity on a residual fuel display apparatus 1d. In the case where the fuel is fed as a car stops and IGN is turned on after ending of an running preparation after the turning on of IGN, the response ability of display is quickened so that the display apparatus 1d may follow the variation of an oil feed quantity, and on the other hand, during running, the response ability is made slower to remove the glittering of the display. Thus a display having no disorder feeling can be obtained according to a user's using state, and moreover the display to accurately follow the oil feed quantity can be secured even in the case of the turning on or off of IGN.

Title: Image processor and recording medium
Inventor: TANAKA SUMIYO
IPC: G06F3/048
Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To extract a feature color from many types of colors and also to automatically extract hues without extracting only similar colors even in extraction of plural feature colors by extracting hues as a feature color of a processing object image among hues based on the result of counting the appearance frequency of hues in each hue and in each hue group. SOLUTION: A hue group that has the most counts is selected in a color taste group table (S5482). Next, the hue that has the most counts is selected among the hues which are included in the selected hue group (S5483). The selected hue is made a feature color for an image (S5484). The count of the hue group which includes the hue as the feature color is reset so that it may not be selected in the feature evaluation (S5485). Thereby, one hue in each group is extracted as a feature color about a hue group in order of appearance frequency. Therefore, the feature colors of only similar colors are prevented from being extracted.

Abstract: PROBLEM TO BE SOLVED: To supply a voltage to cancel a useless voltage induced in a magnetic head due to an external magnetic field by electrically connecting an external magnetic field canceling element to the magnetic head in the vicinity of the magnetic head. SOLUTION: An induced voltage e" is generated in a coil 9 wound inside the external magnetic field canceling element 7 by the magnetic field 23 due to a motor 6, and by adjusting the set-up direction of the magnetic field canceling element 7 so that this voltage e" is deviated 180 deg. phase from the voltage e' generated in the coil 8, e"=-e' is obtd., and the useless voltage e' is canceled by the induced voltage e" generated in the coil 9. Thus, an input voltage to an amplifier 11 becomes only the (e), and the effect of the external magnetic field is canceled.  The voltage (e) from a magnetic recording medium induced in the magnetic head 1 comes from the external magnetic field due to the motor 6, and since the voltage (e) is larger than the induced voltage e', (e)>e', the external magnetic field canceling element may obtd. only by winding wire around a magnetic core for several times.

Title: Production of cast ingot of composite metal
Inventor: FUJII TETSUYA
IPC: B22D7/02
Filed: 1979-07-02
Abstract: PURPOSE: To easily obtain a composite steel ingot of good quality by filling an inert gas in the cavity of the hollow steel ingot at the time of injecting the molten steel forming central layers.  
     CONSTITUTION: A pressure gas is put into, for example, a tank 1, through a lead- in pipe 4 to increase its pressure. Molten metal 3 for outer layers in a ladle 6 is press-fed into a mold 2 through a pouring pipe 8 and when the level of the molten steel being poured reaches the predetermined height of the mold 2, the pressure in the tank 1 is maintained in that state to allow freezing to progress. When a cylindrical shelly hollow metal ingot of a fixed thickness is obtained, the pressure in the tank 1 is successively lowered to return the unfrozen molten metal 3 into the ladle 6, thereby making an outer layer portion. Next, an inert gas such as Argon is successively supplied through the leak hole 9 in the upper part into the cavity and the molten metal forming central layers is injected, whereby the composite steel ingot is obtained. Since the unfrozen molten steel is discharged by the pressure, its discharging becomes easy and since an inert gas is used, the formation of oxide scale is prevented and quality is improved.
