Title: Control of pelton turbine
Inventor: KUSHIMOTO SHIYOUICHI
IPC: F03B15/20
Filed: 1984-04-23
Abstract: PURPOSE:To shorten the stopping time considerably by temporarily holding the close position of deflector at the position further in rotary direction than the close position under like operation upon interruption of load thereby applying hydraulic braking force onto a runner. CONSTITUTION:A horizontal shaft Pelton turbine will perform work by injecting pressure water led through curved inlet tube as high speed jet 3 through a nozzle 2 to the outercircumference of runner (not shown), where a needle 7 to be controlled through a servo motor is incorporated in the nozzle 2 to regulate the flow. While a deflector 9 is journaled rollably at the end of the nozzle 2 to rotate upon abrupt decrease of load and to deflect the jet 3 from the direction of runner through the water receiving face 9b. Here, the deflector 9 is further rotated than the close position under discharge operation upon interruption of load to collide the divided flow 3b flowing out of the trailing edge of the water receiving face 9b against the runner thus to produce the braking force.

Title: Electromagnetic coupling device
Inventor: KOBAYASHI RIYOUJI
IPC: F16D27/112
Filed: 1982-05-13
Abstract: PURPOSE:To automatically adjust a gap between a lining and an armature by spline-pressing a hub into a boss and making an axial moving load of the boss smaller than the attracting force of an excited coil. CONSTITUTION:When an adapter 5a is brought into contact with a retaining ring 8, the friction surfaces of a lining 4 and an armature 5 produces a gap for its worn portion. Since the attacting force of an excited coil 2 is larger than the pressing moving force of spline teeth 7b, 11a, a boss 7 is moved to the lining 4 by an adapter 5a of the armature 5 through the retaining 8. When the excited coil 2 is deenergized, the armature 5 is restored until the adapter 5a contacts a convex portion 7a by the elastic force of a leaf spring 6, so that a gap between the lining 4 and the armature 5 is set at (g).

Abstract: PROBLEM TO BE SOLVED: To make formable a highly precise spot on the information surface of an optical disk. SOLUTION: A curved surface, which is concaved with respect to an optical disk 1, is formed on the top surface of a slider section 13 of an optical head.

Title: Automatic positioning method for consumption type lance of molten steel heating device
Inventor: MIYASHITA YOSHIICHI
IPC: C21C7/072
Filed: 1986-04-11
Abstract: PURPOSE:To perform stable heating-up treatment of a molten steel by adjusting the lifting speed of a lance of the value measured with the flow rate of a blowing gas from the ratio between the erosion quantity at the top end of the lance and the flow rate of the blowing gas and controlling the distance between a molten steel surface and the top end of the lance so as to maintain the specified distance. CONSTITUTION:The distance L0 between a ladle installation surface 12 and the molten steel surface 10 in a ladle 7 and the distance L between a detector 8 for the top end of the lance and the surface 12 are inputted to a feed forward control circuit 11. The lance 6 is lowered and stopped at the distance l0 from the surface 10, then the blowing gas is blown out of the lance. The lance 6 is thereafter lowered at the speed meeting the erosion rate of the lance from the data on the ratio between the volume of the blowing gas calculated from the input up to the previous time by the volume of the blowing gas and the erosion quantity of the lance. The lance 6 is raised upon completion of the heating-up treatment. The lance 6 is stopped at the point of the time when the eroded top end of the lance passes the detector 8. The ascending distance of the lance is then measured by a detector 4 and the erosion quantity of the lance is measured. The measured value and the volume of the blowing gas are inputted to the control circuit 11 and are used as the data for adjusting the lifting speed of the lance in the succeeding period.

Abstract: PURPOSE: To reduce dynamic rigidity by extending a spiral ditch in the interior of an outer supporting sleeve, arranging a compression stopper fixed in a bush inside a working chamber, and forming overflow gaps having respectively predetermined size between the longitudinal side wall and chamber wall at radial outside. CONSTITUTION: A ditch 9 is spirally extended in the interior of outer supporting sleeve 2, a compression stopper 15 fixed in bush 3 is arranged in the interior of a working chamber 7, the stopper 15 is rectangular in plane figure and is sideward projective from the bush 3 forming a wing shape, overflow gaps 16 having respectively predetermined size are formed between the longitudinal sidewall of the stopper 15 and the chamber wall 17 positioning at radial outside. When the bush 3 and the supporting sleeve 2 moves relatively to cause the volume changing of the working chamber 7, a separate flow flows through the gap 16 regardless of the liquid exchange of the regulating chamber 8 through the overflow ditch 9.  Therefore, the dynamic rigidity of the supporting assembly 1 is reduced in a wider frequency band by the liquid movement of the wing 20, 21 of the stopper 15, which are easily to be bent.

Title: Optical head for optical disk
Inventor: NOMURA HIROO
IPC: G11B7/13
Filed: 1984-04-24
Abstract: PURPOSE:To stabilize the intensity of the light entering a photodiode by subjecting the light incident on the photodiode to filtering at variable transmittivity by using a liquid crystal. CONSTITUTION:A nematic liquid crystal material is used for a liquid crystal 15 and the molecules thereof are oriented with 90 deg. twist by the interaction with the boundary of a substrate 12 and are thus made into a single domain. Polarizing plates 16 are disposed on the outside of the liquid crystal cell in such a way that the polarizing directions thereof cross each other. The polarizing directions coincide with the orientation of the liquid crystal molecules at the boundary of the substrate 12. The incident light is polarized by the plate 16 on the incident side and the polarized light is rotated along the twist of the liquid crystal molecules when the light is made incident on such liquid crystal device. The light transmits the analyzer as it is while no voltage is impressed to the cell. The liquid crystal molecules begin to move so as to parallel with the electric field direction and the initial twist structure begins to collapse when the voltage is impressed to the cell. The desired change of the quantity of the light entering the photodiode of the optical head is thus made possible if the voltage to be impressed to the liquid crystal 15 is set between V1 and V2.

Abstract: PROBLEM TO BE SOLVED: To widen the range of use applications of a paper solidified product, thereby increases the quantity of recycled waste paper by impregnating a paper with an aqueous solution containing an aqueous paper solidified product forming component of alkaline silicate and drying the paper to solidify the permeation solution. SOLUTION: A paper is impregnated with an aqueous solution of alkaline silicate (silicate) and addition products are individually and simultaneously mixed with and dispersed into the aqueous solution. The silicate is a silicate itself or a mixture of the silicate and other components which is called a soluble glass or a liquid soluble glass. The additives to be combined with the soluble glass are a hydrochloric acid, an aluminum phosphate or the like and in addition to the acid and a basic compound, are such as amines or a carbonic acid gas. Theses additives work as a curing agent and a curing promotor for the aqueous solution of the silicate.  In order to solidify the paper impregnated with the aqueous solution of the silicate, a mixture of the aqueous solution and the additives or the aqueous solution of the silicate or the additives are individually sprayed or spread over the paper after adjusting the concentration, or the aqueous solution and the paper are mixed simultaneously and the paper is dried to cure the aqueous solution after impregnation. Thus it is possible to obtain the paper solidified product with high heat resistance and superb resistance to a solvent and an oil, and expand the use applications of the paper setting product.
