IPC: H04B17/00
Filed: 1983-05-04
Abstract: PURPOSE:To enable measurement of disturbing wave excluding capacity under worst condition at high reproducibility by providing an annular magnetic substance core on which the tip of a coaxial cable is wound, a resistance made by connecting a coaxial outer cover conductor and a center conductor, and a cylindrical magnetic substance to be placed on the injected line. CONSTITUTION:Resistance value of a resistance 15 is selected equal to characteristic impedance of a coaxial cable 14. A wire to which disturbing wave is to be injected, for instance a feeder 3, is passed through an annular core 12 and a cylindrical magnetic substance 13. An artificial disturbing wave generator 11 is started while operating an electronic device 2. The artificial disturbing wave is injected to the feeder 3 by transformer coupling through the annular core of the feeder 3 and coaxial cable 14. The output is increased slowly, and the core 12 is moved along the feeder under each output condition. Output of the disturbing wave when the electronic device 2 makes malfunction indicates disturbing wave excluding capacity of the electronic device 2. The magnetic substance 13 acts as a resistive terminator, and the position of the core 12 that matches output impedance of the artificial disturbing wave generator 1 exists in it. At that time, the electronic device shows the lowest disturbance excluding capacity.

Title: Information transmission system
Inventor: TSUMURA TOSHIHIRO
IPC: G01S5/16
Filed: 1993-03-10
Abstract: PURPOSE:To provide the information transmission system which can reduce the state of disabling the transmission of information, can reduce the erroneous recognition of information, can be utilized for any large scale system as well and further can increase the quantity of information. CONSTITUTION:An information transmitter 30 successively sends the plural kinds of information to corner cubes 11. A beam light transmitter/receiver 21 scans the corner cubes 11 by turning a planar laser beam LB. Since the width of this laser beam LB is wide in a scan direction and a vertical direction, the small corner cubes 11 can be easily irradiated with the laser beam LB even when an optical axis center S is deviated a little. Thus, the beam light returns from the corner cubes 11 to the beam light transmitter/receiver 21 without fail. On the other hand, since the entire faces of corner cubes 11a-11c are scanned, the reflected light to return to the beam light transmitter/receiver 21 contains all the information. Further, since the reflected light successively contains the plural kinds of information, the quantity of information is considerably increased.

After being laminated with a protective layer if necessary, said silicone rubber layer is exposed and developed. As the result of development, only the silicone rubber layer on the exposed part is removed and the photodetective layer remains because it is unsoluble in the developing solution through bridge or denature. A printing board is completed by heat fixing.

Title: Productin of storing case of magnetic tape cartridge
Inventor: KAGANO SHINICHI
IPC: B29C45/26
Filed: 1982-05-12
Abstract: PURPOSE:To increase the strength of a storing case of a magnetic tape cartridge and to improve the external esthetic appearance of the case, by using a die provided within a region formed by connecting a gate position having an intersection between a rotary bottom and a coupling plate with the tangent line of a through hole, and producing a rotary cover. CONSTITUTION:A gate J is set within a region 2 which is formed by connecting an intersection 23 between a rotary bottom 13, a coupling plate 14 and an end plate 16 and the tangent line of a through hole 15. Therefore the synthetic resin injected from the gate position M touches a slide pin K inserted for drilling the hole 15 and is branched to upward and downward parts. These upward and downward flows of resin join together at the downstream of the pin K to form a weldline from the intersection 23 through a ridge line 25. The line 25 corresponds to the position where the strength of the cover 3 is maximum. Therefore the weldline never cracks by an impact. In addition, a gate track L is covered by a side wall 7 of a case main body 2. As a result, the strength of a storing case is increased for a magnetic tape cartridge along with improvement of the external esthetic appearance of the case.
