Title: Treatment for silicomagnesia nickel ore
Inventor: HASEGAWA KAZUO
IPC: C22B23/00
Filed: 1987-04-03
Abstract: PURPOSE:To recover Ni and Fe in the form of oxides and also to recover and recycle HCl gas, by treating silicomagnesia nickel ore with hydrochloric acid to leach out Ni, Fe, and Mg in the form of chlorides, respectively, by concentrating and solidifying the resulting leach liquor, and then by carrying out oxidizing roasting. CONSTITUTION:Silicomagnesia nickel ore containing SiO2 and MgO as principal gangue components and also containing small amounts of NiO and FeO is pulverized to <=80 mesh, which is treated with an aqueous solution of HCl to leach out Ni, Fe, and Mg into the aqueous HCl solution in the form of chlorides, respectively. The leach liquor is separated from the residue composed principally of SiO2 and then evaporated so as to recover unreacted HCl gas and also to concentrate the leach liquor and further hold the above at <=350 deg.C to undergo evaporation and solidification of the leach liquor. The solidified substance is subjected to oxidizing roasting at 250-450 deg.C so as to form the chlorides of Ni and Fe into oxides, respectively, and also to inhibit the oxidation of MgCl2 into MgO. Then water washing is applied to separate MgCl2 from NiO and FeO in the form of an aqueous solution, and Ni and Fe can be recovered in the form of a mixture of NiO and FeO in high yield.

Title: Screen of back projection
Inventor: TAKAHASHI HIDEO
IPC: G03B21/625
Filed: 1982-05-14
Abstract: PURPOSE:To obtain a back projection screen which is especially suitable to a color television by forming a non-circular lenticular deisgned so that the distribution of transmitted light exceeds a specific value at a beta value on the observation side of the screen so that a specific base part is formed. CONSTITUTION:The optionally designed non-circular lenticular 11 is formed on the observation side of a screen medium 1 consisting of polymethacrylate or the like so that the distribution of transmitted light exceeds 25 deg. at the beta value. In addition, the width of the base part P1 is set to about one tenth of the pitch P of the lenticular and its inclination theta' is set to 45 deg. or more so that the base part fully reflects parallel incident light and distributes the light made incident from the inclined diretion at an optional ratio. An circular Fresnel 12 is formed on the projection side of the medium 11. Thus said procedure provides the screen especially switable to a color television because of a large visual field angle, small color variation and even distribution of transmitted light. If a diffusing agent 2 such as SiO2 is dispersed to the medium 11, the brightness is controlled and the visual field angle can be expanded in the vertical direction.

IPC: H03H5/02
Filed: 1985-04-18
Abstract: PURPOSE:To obtain a variable tuning circuit whose fractional band is large by only adjusting two pieces of variable coils, by constituting it so that a variation of a frequency variation characteristic of a series resonance circuit and a bimatching circuit is reversed, and a uniform characteristic is obtained synthetically. CONSTITUTION:A series resonance circuit containing a variable coil LV1, a capacitor C1 and an input terminal 1 executes an action for giving a high impedance to a characteristic, namely, a higher harmonic, as a load of a D-grade amplifier. As for an impedance transformer T, it suffice that it is operated as a matching circuit of 13OMEGA:50OMEGA, but in reality, even in case of 1:2 by a turn ratio, namely, 12.5OMEGA:50OMEGA by an impedance ratio, the input impedance can be set to an optional magnitude of 13OMEGA or about 13OMEGA by setting the LV1 and the LV2. It is because a reactance portion generated by detuning the series resonance circuit a little, the C2 and the LV2 constitute a matching circuit of T- type.

IPC: F22B37/24
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To perform a design and manufacture independently from a main part and to shorten a manufacture period by a method wherein a frame of an angle material is welded to the periphery of a deck plate to cover an approximately rectangular range surrounded with girders to form a floor panel, which is fixed at the girders. SOLUTION: A deck plate 1 is formed at a frame 2 formed by using an angle material and a welded integrally formed floor panel. The deck plate is manufactured at a factory prior to a work at a site. A drain hole 4 and a bolt hole 5 to mount the floor panel on a girder 3 are formed in the deck plate 1 and a floor panel and the girders 3 are coupled together by means of high strength bolts. Since the deck plates 1 are disposed throughout the whole surface of the span of a steel girder 3, the deck plate has floor beam and horizontal brace functions. After floor framing is completed, a floor material is arranged on the upper surface of the floor framing in a spot where an inspection passage is needed. This constitution brings deck plate floor framing into a block at a factory and facilitate mounting on the girder.
