  • Patent number: 7023686
    Abstract: A high-voltage ceramic capacitor which includes a capacitor element, at least one metal terminal, and at least one solder joint portion. The capacitor element has electrodes on opposing surfaces of a ceramic porcelain. The metal terminal has one end surface facing one surface of the electrode. The solder joint portion is interposed between one end surface of the metal terminal and one surface of the electrode, and solders both surfaces. The solder constituting the solder joint portion does not contain lead but inorganic particles having a melting point higher than a solder melting point.

  • Patent number: 7019459
    Abstract: A structure for preventing glass from breaking, having a combination of a surface glass breaking prevention material, a glass substrate and a metal plate arranged in the order, wherein an internal glass breaking prevention material made of an elastomer or viscoelastomer having a dynamic shear modulus of not larger than 1×109 Pa is interposed between the glass substrate and the metal plate. Particularly, in the glass breaking prevention structure configured as described above, destructive impact energy (B) by which the glass substrate is destroyed when a steel ball 50 mm in diameter and 500 g in weight is dropped on the surface glass breaking prevention material is not lower than 1.2 times as high as destructive impact energy (A) measured in the same manner upon a glass breaking prevention structure having the same configuration as the first-mentioned structure except that the internal glass breaking prevention material is not interposed.

  • Publication number: 20050168912
    Abstract: The present invention is directed to a high-voltage capacitor, high-voltage capacitor device and magnetron in which, undesirable radiation waves generated in the frequency range of 450 MHz to 1000 MHz in a magnetron are suppressed to such a level that there is no adverse effect on the peripheral devices. The dielectric porcelain comprises a body 210 and through holes 211, 212. The body 210 includes a portion (216, 217) that is narrowed on both sides in the middle of the body in the plan view. The through holes 211, 212 are formed in the body, arranged at a distance from each other over the narrowed portion (216, 217). One individual electrode 213 is provided on the surface of the body 210 at which the through hole 211 opens. The other individual electrode 214 is provided on the surface of the body 210 at which the through hole 212 opens. The common electrode 215 is provided on another surface of the body 210 at which the through holes 211, 212 open.

  • Patent number: 6909590
    Abstract: A capacitor has electrodes at surfaces thereof, with one of the electrodes secured onto one surface of a grounding metal. Through conductors pass through the capacitor and the grounding metal and are connected to the other electrodes so as to achieve electrical continuity. An insulating case is provided at one surface of the grounding metal, with one end of the insulating case fitted around the external circumference of the raised portion of the grounding metal. Insulating resin fills a space inside the insulating case, the internal space of the grounding metal and a space around the capacitor. The insulating resin comprises an epoxy resin containing a brominated fire retardant, and the brominated fire retardant is a brominated aromatic glycidyl ether.

  • Publication number: 20040162112
    Abstract: When a name card management program as a user's function of a portable telephone set 1 is started, a name card producing function 100 is selected by a menu key (or M key), and a desired name card pattern is read out for producing name card data. The produced name card data is stored in a memory. For name card exchange, the telephone number or mail address of the opposite side terminal is inputted and transmitted by confirming that the own name card data preserved in the memory has been read out and displayed on a display unit. By designating reservation in the presence of display of name card data, which has been received from the opposite side terminal, on the display unit, the received name card data is stored in the memory.

  • Patent number: 6672778
    Abstract: At least two (groups of) sensors forming an insertion detection sensor are offset from each other in the conveyance direction of a photosensitive material. An insertion speed, which is different for each manual insertion event, is obtained based on the time difference when sensors that have been offset from each other detect the leading end of the photosensitive material. The length of the photosensitive material in the conveyance direction thereof is accurately computed based on the insertion speed and other information. By correcting the errors due to the changeable insertion state of the photosensitive material caused by manual insertion by the operator, the process area of the photosensitive material, required for calculating the amount of replenisher to be replenished, is accurately obtained. Therefore, the amount of the replenisher is appropriately determined and the process capacity of the developer or the fixing solution can constantly be maintained at the satisfactory level.
