Abstract: An impact-activated toy suitable for use in a child's crib which is capable of generating a series of melodies in response to successive impacts by a child spaced by more than, for example, ten minutes from the termination of the preceding melody. A momentary push-button switch for the mother's use is provided to cause the toy to generate a series of melodies in response to actuation by the mother when no melody is being generated or to stop the generation of any melody being generated at the time of the switch actuation.

Abstract: An improved infusion bag for preparing an infusion of tea or other infusible substances, comprising a sachet member of liquid-permeable sheet material and a pull string. The pull string is joined at the upper apex of the sachet. At least one ventilative slit is provided below the joint point of the string and the upper apex of the sachet. The sachet can be folded into a generally tetragonal shape. After steeping, and by the action of withdrawing and submerging, the infusible substance swells and sinks to the lower apex of the sachet. The improved infusion bag makes the infusible substance less compacted and overcomes the constraint due to the capillarity of the liquid-permeable sheet material itself and the interface capillarity of the mass of the infusible substance. This gives a higher quantity and higher concentration of infusion liquor.

Abstract: A grain handling system comprises a valve device for controlling a flow rate discharged from a downstream end of at least one flow passage. A volumetric weight measuring device measures the weight per unit volume of the grain delivered toward the valve device to generate a volumetric weight signal. A computer generates a control signal on the basis of the volumetric weight signal. A drive device drivingly connected to the valve device is operative in response to the control signal to drive the valve device so as to allow the grain discharged from the valve device to be controlled in terms of weight unit.

Abstract: The flameproofed water-repellent sheet of the present invention has a construction that a sheet-form base material consisting of a woven or knitted fabric of organic fiber is impregnated with a silicone resin varnish containing at least a fibrous potassium titanate and said silicone resin varnish is dried and cured. Since it has excellent non-flamability and water-repellency and, in addition, a flexibility and a high sewing suitability and a high folding endurance, it can be utilized quite effectively as a tent fabric for large-sized tents, storehouse type tents and the like and as a wall material for pool, and the like.

Abstract: The oxygen-permeable hard contact lens of this invention produced by polymerizing in a composition composed of 30 to 50% by weight of an alkyl (meth)acrylate, 10 to 40% by weight of a fluorine-containing monomer, 10 to 35% by weight of a silicone (meth)acrylate, 5 to 15% by weight of an unsaturated carboxylic acid and 0.1 to 15% by weight of a di- or tri(meth)acrylate of a dihydric or higher hydric alcohol by raising a temperature continuously or stepwise from 40.degree. to 100.degree. C. and processing the resulting polymer into a lens shape by ordinary mechanical processing and polishing, is excellent in stain resistance, scratch resistance and hydrophilicity.

Abstract: In a process for producing a polymer of monoallylamine comprising polymerizing monoallylamine, the polymerization is carried out using as a monomer inorganic acid salts (e.g., hydrochloride, sulfate, etc.) of monoallylamine in the presence of an azo type radical initiator.By the process, polymers of monoallylamine having a high degree of polymerization can be obtained in high yield.

Abstract: A surgical instrument for cutting a lens of a human eye inside the eye for removal through a small incision in the cornea. The instrument has a flange at its front end and a snare loop extending through the flange for ensaring the lens and cutting the same while the lens is supported by the flange.

Abstract: A digital control method for controlling a relative rotational phase angle p.theta. or the like in a fuel injection pump of an automobile. Decision is made of whether two successive deviations Er between the detected values and a target value are larger than a minimum reference deviation Ero or not. If they are larger than the Ero, decision is made of whether the signs of both the deviations are positive and/or negative. If both signs are positive, a given duration dTs is added to a fundamental duration ts of the next command signal for control. If both signs are different, a predetermined duration dTs is subtracted from the fundamental duration ts of the next command signal.

Abstract: An intraocular lens and method of positioning the same in an eye in which the lens includes a layer of material which is soluble in the eye for maintaining the position-fixation members of the lens in contracted condition during insertion thereof into the eye.

Abstract: A method of cleaning a machined surface comprises: mounting a chip removing tool having two flow paths for compressed air and cooling water, respectively, on a main spindle of a machining center; and simultaneously jetting out the compressed air and cooling water from a mutual outlet, thereby to remove chips attached to a machined surface of a workpiece.A chip removing tool, for use in the above method, which includes a rotatable body attachable to a main spindle of a machining center, has a casing and compressed gas and liquid supply in the casing.

Abstract: A surgical instrument having a shank and a hook at one end of such shank with a transversely extending tip for seating the lens in the posterior chamber of the eye with the neck of the hook having a first portion adapted to extend along the anterior side of the iris, a central portion adapted to extend through the pupil and a second portion having said tip adapted to extend along the posterior side of the iris with the tip extending substantially to an inner peripheral surface of the posterior chamber of the eye.

Abstract: A method of detecting the timing of fuel injection in a diesel engine for the regulation of the timing of fuel injection by a fuel injection timing regulator is disclosed. Rotation angle indicating lugs are provided on the crankshaft of the engine connected to the input shaft of the fuel injection timing regulator and on the output shaft of the fuel injection timing regulator to measure the time difference between pulses corresponding to the lugs on the input and output shafts making relative rotation, and a reference rotation angle indicating lug is provided adjacent to each of the lugs provided on one of the input and output shafts to measure the reference timing difference between pulses corresponding to the lugs on the shaft under rotation. The phase angle of the output shaft relative to the input shaft can be accurately calculated on the basis of the former and latter time differences.

Abstract: A machine for embossing comprises a pair of co-operating rollers parallel to but spaced from one another, and two pairs of pinch rollers also parallel to and spaced from one another, one pair of pinch rollers being effective to firmly grip a workpiece before it enters the embossing zone. One set of pinch rollers is located at each respective side of the embossing rollers, and a retractor coupling the upper roller of each said set to the machine frame, arranged in one mode to firmly grip the workpiece and in another mode to be clear of the workpiece. This arrangement enables the rolling machine to operate in two directions.

Abstract: A new intraocular lens, suitable for use in artificial lens implantations and having a light-focusing lens body and two position fixation means therefor, is disclosed. One position fixation means extends generally radially from a first region of the periphery of the lens body and the other position fixation means comprising a pair of support members extends generally radially from a second region of the periphery of the lens body spaced from the first region. At least one of the support members of said latter position fixation means is resiliently deformable between a normal undeformed condition, in which the entire lens will not pass through an incision in the eye of a given length and a deformed condition, in which the entire lens will pass through such given incision. During insertion of the lens into the eye, sufficient force is applied to the deformable position fixation means to maintain it in the deformed condition thereof.
