TiS2 belongs to a layer-like transition metal chalcogenide and has a crystal structure of hexagonal system. When lithium ions are mixed into this TiS2, they penetrate into the octahedron of the TiS2- crystal inter-layer and the inter-layer compound represented by LixTiS2 can be obtained. This negative active material is added with a binding agent (fluororesin) to make a mixture, which is press-molded to a stainless steel wire net that is to be a plate core body, namely a negative electrode 4. On the other hand, V2O5 powder is added with a conductive agent and a binding agent to make a mixture, which is press- molded to a stainless steel wire net that is to be a plate core body, namely a positive electrode 2. The electrolytic solution is a mixed solvents of equal volume ratio of propylene carbonate and dimethoxyethane into which 1mol of lithium perchlorate is dissolved. A separator 5 composed of a polypropylene non-woven cloth is impregnated with this electrolytic solution to produce the captioned battery.

Filed: 1980-07-21
Abstract: PURPOSE: To prevent the generation of high frequency noise by providing a projecting wall along a rotary surface of an impeller from the inside wall of ventilating channel near a baffle and by selecting the height and thickness of the projecting wall.  
     CONSTITUTION: Projections walls 14 and 15 start from the bottom 12b on the inside diameter side of the inside diameter wall 12 for an extended wall 12 as well as the bottom 12C on the outside diameter side.

Abstract: PURPOSE:To detect the approach angle of a car with satisfactory accuracy regardless of the approaching direction of the car, by setting copying sensors in parallel to each other with a prescribed space between them and adding another sensor at the front oblique position of both of above-mentioned copying sensors. CONSTITUTION:The approach angle of a car is detected by setting copying sensors in parallel to each other with a prescribed space between them and providing another sensor added at the front oblique position of both copying sensors. That is, a detection signal is transmitted to a controller 9 from an optical sensor S1 when a car approaches obliquely with angle theta to a boundary of traveling areas of the car. A counter 13 is started by a pulse signal delivered from a distance sensor 5. Then the counter 13 is stopped by an optical sensor S2 when the car approaches further. The traveled distance (x) of the car is calculated from the count value of the counter 13 counted hitherto and the unit traveled distance. Then the approach angle theta is detected from the distance (x) as well as the attachment space and angle between both sensors. A hydraulic cylinder 6 is driven via a buffer 15 and a solenoid valve 14 so as to obtain a steering degree corresponding to the angle theta.

Abstract: PURPOSE:To regulate a whole output picture to a picture having uniform density to an output to an output recorder such as printer, by binarizing a part of the image on a photographic film where the density is particularly high or low with a threshold different from a threshold of other parts. CONSTITUTION:The part of the microfilm F whose density should be varied is designat ed by means of cursors 29 and 30. Then, to what degree the density of the part should be made higher or lower than that of other parts is specified by an in-cursor density specifying variable resistor 34. The voltage value thus specified by means of the resis tor 34 and a prescribed voltage value from a density specifying circuit 48 are added with each other in an adder 50, and the result is supplied to the inverse input terminal of a comparator 52. Under the control of a CPU 43, the comparator 52 outputs the binary image signal whose density-component is adjusted with a specified threshold only during the time a CCD 6 is scanning the area inside the cursor frame. Consequent ly, such picture signals as of a prescribed normal density for the areas outside the cursor frame and as adjusted to be of the specified density for the area inside the cursor frame, are obtained from a multiplexer 53, and accordingly image signals of the same density are recorded in the output recording device 100.

After molding sand is contained in a blow tank 19, the tank 10 is moved to position a blow port 12 and the opening part of metal molds 11 correctly; further while the tank 10 and the molds 11 are held in press contact with each other, pressurized air is supplied to the inside of the tank 10 and  molding sand is forced into the molds 11 through the blow port 12. Namely, the  molding sand is transferred from the opening part of the sleeve to the blow part  12 through the clearance between the cap 18 and the sleeve 14, whereby the  core of the inside shape of the metal molds is manufacutured. In this case, the  entry of the molding sand into the molds 11 prior to forcing of the molding sand  terein is obviated, and the core of smooth casting surfaces is obtained.
