  • Patent number: 9331496
    Abstract: Contactless power-feed equipment includes: a power-supply device that outputs an AC constant current having a predetermined oscillation frequency to a main induction line; a primary coil provided on the main induction line connected to the power-supply device; a secondary coil that forms an insulating transformer with the primary coil and is connected in parallel with the sub induction line, a resonance capacitor that is connected in parallel with the secondary coil and constitutes a parallel resonant circuit with the sub induction line, and a switch provided between the secondary coil and the parallel resonant circuit. In the parallel resonant circuit, the sub induction line and the resonance capacitor have constants such that the parallel resonant circuit has a resonance frequency equal to the oscillation frequency of the power-supply device.

  • Patent number: 4538341
    Abstract: A machine tool having an automatic tool changer for transferring tools between a tool magazine and a horizontal tool spindle rotatably mounted in a spindle head and which includes a vertical head which rotatably carries a vertical tool spindle and a horizontal drive shaft connected thereto is removably mounted on a vertical head support. In advance of a machining operation on a top surface of a workpiece, relative movement between the vertical head support and the spindle head is effected in a vertical direction and first and second horizontal directions, so that the vertical head is mounted on the spindle head, with the drive shaft being drivingly connected with the horizontal tool spindle. A tool support station mounted on the vertical head support is provided with two tool grippers each for vertically holding a tool.

  • Patent number: 4513366
    Abstract: A numerical controller for a machining center comprising a microprocessor connected to a data input device, a CRT display device and a data storage device. The microprocessor prepares an NC program for a workpiece to be machined, based upon machining information manually input by the use of the data input device and stored in the data storage device. The debugging of the prepared NC program is then executed, wherein the microprocessor obtains by calculation a workpiece interference space defined outwardly from the outer periphery of the workpiece, based upon workpiece blank shape and dimension data and workpiece mounting position data stored in the data storage device. The microprocessor further calculates, based upon the NC program, a tool path along which a tool spindle of the machining center would be moved relative to a work table in accordance with the NC program.

  • Patent number: 4405597
    Abstract: The invention provides a novel means for the administration of a therapeutically effective ingredient in the form of a rectally applicable medicament capsule, in which the otherwise unavoidable extreme variation in the absorbability of the effective ingredient among the individuals rectally treated with the capsules is minimized. It has been unexpectedly found that, when the effective ingredient is contained in the capsule in the form of a liquid medicine, the osmotic pressure of the liquid content plays a very essential role in the absorption of the effective ingredient through the rectum and the variation in the absorbability of the effective ingredient among the individuals can be minimized when the osmotic pressure of the liquid content is substantially higher than the osmotic pressure of the rectal fluid with which the capsules are contacted.

  • Patent number: 4402692
    Abstract: The invention provides a novel and efficient means for the administration of a therapeutically effective ingredient by rectal application in the form of a medicament capsule encapsulating the effective ingredient. The medicament capsule according to the invention is formed of a hard capsule shell made of a mixed ester of a cellulose ether, e.g. alkyl-, hydroxyalkyl- and hydroxyalkyl alkylcelluloses, esterified with aliphatic monacyl groups and acidic succinyl groups. When the capsule is inserted into the rectum, the capsule shell is disintegrated and the rectally absorbable effective ingredient is readily and smoothly released into the rectum and absorbed to exhibit therapeutical effects as efficiently as with conventional suppositories.

  • Patent number: 4397835
    Abstract: The invention provides a novel means for overcoming the problem of undue and irregular delay in the exhibition of the effect of medicine when a patient is administrated with an enterosoluble hard-capsulated medicament. The unexpected discovery that the key parameter ruling the smooth transfer of an enterosoluble capsule from the stomach to the intestinal canals is the overall specific gravity of the capsule has led to the establishment of the invention which proposes an enterosoluble hard-capsulated medicament having an overall specific gravity of at least 1.05 or, preferably, at least 1.10.

  • Patent number: 4050274
    Abstract: In an apparatus for forming a pair of disk-shaped metal blanks into grooved wheels, a spindle head is mounted on a support base and has rotatably supported therein a spindle for mounting a pair of mounting dies on opposite ends thereof. A pair of clamp heads are mounted on the support base at opposite sides of the spindle head and slidably and rotatably support a pair of clamping dies for clamping two blanks in cooperation with the mounting dies. A pair of brackets are rotatably suppoted on the support base and rotatably carry a pair of rollers for forming the blanks into grooved wheels. The brackets are independently rotated and the rotational movements thereof are individually restricted.
