Title: Ic card
Inventor: AKIYAMA TOMOYA
IPC: G06K19/077
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To provide the IC card of high performance and high physical strength for appropriately housing the sheet-like capacitor of a desired capacity in a narrow mounting area. SOLUTION: For this IC card 100, a substrate 101 is divided into a coil formation area 102 and an IC mounting area 103 and a coil 130 is formed by copper foil in the coil formation area 102. In the IC mounting area 103, an IC 112 is mounted on one surface and the capacitor 120 is formed on the back surface. At the time, the formation area of the capacitor 120 is made larger than the mounting area of the IC 112 on the opposite surface. By that, since the capacitor 120 is formed on the back surface of the IC mounting part, a new area is not practically required. Also, by forming the capacitor 120, the flatness of the mounting surface of the IC 112 is raised and the connection defect of the IC 112 or the like is hardly caused.

Abstract: PURPOSE:To relive the effect onto a circuit characteristic by reducing the connection distance between a pair chip and a conductor layer of a mounted face so as to decrease the inductance component. CONSTITUTION:A recessed part 15 with a pair chip 5 contained therein is formed in a circuit board main body 11 so as to reach a conductor layer 14 of a rear side from a surface conductor layer 13 and a new conductor layer 16 is packed to the recessed part 15 so that the depth of the recessed part 15 is proper for mounting the pair chip 5 therein.

Abstract: PURPOSE:To perform changeover and selection of narrow and wide visual fields through simple operation by making only the secondary mirror part of an afocal optical system changeable to the inside and outside of the visual field of a focal optical system. CONSTITUTION:The secondary mirror 42 of an afocal optical system is made rotatable 90 deg. about the rotating axis 45 orthogonal to optical axis in nearly the intermediate position of a reflecting mirror 421 and a correcting lens 422.

The parallel fluxes then enter the lens 1 having a standard visual field S of a focal optical system and is forcused to a specified position F by the movement and adjusting of the lens 1 to the optical axis direction. When the secondary mirror 42 is turned to the positions 421', 422' of the reflecting mirror 421 and correcting lens 422, the infrared rays directly enter the lens 1 through the opposing clearance of both positions 421', 422' and observation of the standard visual field S becomes feasible.

Filed: 1978-05-24
Abstract: PURPOSE: To make it possible to suppress the temperature rise of a shadow mask with no lowering of the mechanical strength of the mask, by making the surface of the mask rough by a grindstone.  
     CONSTITUTION: The surface of shadow mask 71, surface A-A', is given a shock by grindstone 8 to form depression (e) on the surface, thereby making the surface rough. Roughening the surface in this method hardens the surface by the shock at the time of the formation of depression (e), so that the surface can be roughened to a degree of chemical-etching depending upon the diamater of grindstone 8. As for the surface, the same thermal radiation as chemical-etching can be obtained while the maintenance of the shape of mask 71 is secured owing to the hardening of the surface, and the mass of mask 71 never lessens, so that stable surface structure can be obtained in terms of mechanical strength and unit area.

In which case, the surface of the fine adjustment joint 3 is covered with a heat insulation film 6. The heat insulation film 6 employs a type formed in such a manner that a film made of preferably polyvinyl chloride having an air layer 7 formed therein or a polyvinyl chloride film forms two-layer structure and a star type air layer is formed therebetween.  This constitution provides a given heat insulation effect and prevents the occurrence of condensation of dew.

Title: Connection processing system for telephone exchange
Inventor: TSUTSUI NOBUYUKI
IPC: H04M3/42
Filed: 1989-03-15
Abstract: PURPOSE:To turn telephone exchange system into elastic constitution by managing a connection destination for an intercept call in conformity to a table form, and separating it from a program. CONSTITUTION:When a service request arises from a subscriber's terminal 3, an intercept call detecting part 20' decides whether it is related to intercept processing or not, and discriminates the cause of the intercept processing, and starts a response processor specifying part 22. The response processor specifying part 22 selects a response processor 10 to execute response processing for the intercept call from the subscriber's terminal 3 by referring to an unallowable connection table 21. Thus, because the name of the response processor of the connection destination for the intercept call is managed in conformity to the unallowable connection table 21, and is separated from the program, in such the case where, for instance, the cause of the intercept processing increases, it is enough to add corresponding contents to the unallowable connection table 21.
