  • Patent number: 8101031
    Abstract: A hollow shaft material is provided with, on an outer peripheral surface side thereof, for example, a movable induction heating coil wrapped therearound. While a high-frequency current with a predetermined frequency is caused to flow through the induction heating coil, the induction heating coil is axially moved to perform induction hardening of the hollow shaft material from the outer peripheral surface side. At this moment, the frequency of the high-frequency current caused to flow through the induction heating coil is set relatively low as to the small-diameter portions, which have a relatively small thickness, and the frequency of the high-frequency current caused to flow through the induction heating coil is set relatively high as to the large-diameter portion, which has a relatively small thickness.

  • Patent number: 5987575
    Abstract: A data backup apparatus determines whether a version serial number of data backed up in a network management system matches a version serial number of data stored in a data version serial number management field of an update history management area, upon having the network management system back up update data generated in a data processing apparatus. Upon a match of the version serial numbers of respective data, the data processing apparatus transfers only update data stored in the data update history management area via a communications link to the network management system. Upon a mismatch of the version serial numbers of respective data, the data processing apparatus transfers all data, including data other than update data, stored in an EEPROM of the data processing apparatus, to the network management system.

  • Patent number: 5424093
    Abstract: A thick layer of electrode material paint is formed on a flat surface. A film of the electrode material paint is formed on an element by dipping the element into the layer. In the next step, a thinner layer of the electrode material paint than the aforementioned layer is formed on a flat surface. Into the thinner layer of the electrode material paint, the film of the electrode material paint formed on the element is dipped. Alternatively, the element may first be dipped into a thinner layer of the electrode material paint so that a thin film of the electrode material paint is formed on the element. The film formed on the element is then dipped into a thick layer of the electrode material paint and then again into a thin layer of the electrode material paint in such order. By firing the film of the electrode material paint obtained in this manner, an electronic element having external electrodes of a uniform thickness can be obtained.

  • Patent number: 5120577
    Abstract: An electronic component chip holder employed for coating metallized surfaces on both longitudinal ends of a plurality of electronic component chips with a metal such as solder, while holding the same. The holder comprises a plurality of holding portions for holding the electronic component chips one by one. Each of the holding portions is defined by a through hole, and each of the electronic component chips is inserted in the holding so as to be longitudinally aligned with the axis of the through hole. An elastic member is formed on an inner peripheral surface defining each holding portion, to elastically hold a longitudinal intermediate portion of each electronic component chip. A plurality of electronic component chips thus held by the holder are collectively dipped in a molten bath of a metal such as solder, so that coating films of such a metal are formed on the metallized surfaces.

  • Patent number: 4960195
    Abstract: A component-orienting apparatus provided with a plurality of parallel orienting passages for aligning a plurality of components such as rectangular-parallelopipedic electronic component chips in the same orientation as each other. Each of the orienting passages comprises a receiving portion provided with a first space defined by an upwardly-taperingly-opening first inner peripheral surface and an aligning passage having a cylindrical second inner peripheral surface defining a second space that communicates with the lower end of the first space. The aligning passage is selected to have sectional geometry which rejects the longitudinal dimension of each component but crosswisely and perpendicularly orients the component in prescribed directions respectively. The first inner peripheral surface is continuous with the second inner peripheral surface through a rounded face.

  • Patent number: 4859498
    Abstract: A chip component holding plate includes a sheet member composed of silicon rubber, on which a number of quadrilateral through holes each of which is capable of holding a chip component therein are formed. A plate composed of stainless steel is formed on one main surface of the sheet member. On the stainless steel plate, a number of circular through holes each of which has a diameter larger than an inside width of each quadrilateral through holes of the sheet member are formed at positions respectively corresponding to the respective through holes of the sheet member. In the state that the chip components are respectively press-inserted into the respective through holes of the sheet member, the stainless steel plate is magnetically attracted by a magnet plate. Then, the magnet plate is moved so that end portions of the respective chip components being held by the sheet member are pressed onto a silver paste which is spread on a plate, whereby an electrode is applied on the end portion of each chip component.

  • Patent number: 4853524
    Abstract: The present invention concerning the Optical Identification Card System is provided with an individual card which emits infrared light modulated by the individual code and a detector which receives this infrared modulated light and detects the individual code. When a request signal is radiated from this detector as infrared light from the above within the prescribed light-emitting area, the said infrared modulated light is radiated from the individual card within the light-emitting area and thus the individual code is detected by the detector. Then the detected individual code is identified by the identifier, and on the basis of this identification result, the terminal equipment related to the holder of the individual card is actuated, thereby automatically locking and unlocking the door.
