Title: Tape cover of cassette case for videotape
Inventor: HOSONO NOBUYOSHI
IPC: G11B23/087
Filed: 1984-09-22
Abstract: PURPOSE:To avoid occurrence of flow marks caused by molten resin that becomes resin cakes by forming a slope opposite to a gate for injecting resin inside of a corner where an upper plate and a front plate join. CONSTITUTION:In the tape cover 5, a slope 5d is formed at a position opposite to a gate 3 for injecting resin outside of a corner where an upper plate 5a formed to L-shaped sectional form and a front plate 5b join, and a reinforcing part 5e is formed inside. When injection forming, molten resin injected from the gate 3 hits on the wall face of a cavity that forms the reinforcing part 5e and flows branching as shown by dotted line arrow marks. Highly viscous resin stagnating in the gate 3 is dispersed in the period of interruption of injection of molten resin, and mixed with molten resin and diffuses in the cavity. Thus, it does not stop becoming resin cakes, and no flow mark occurs on the surface of the tape cover 5.

Title: Lapping machine with fastening mechanism for suspension bridge cable
Inventor: SAKAMOTO YOSHIFUMI
IPC: E01D11/02
Filed: 1995-08-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to execute lapping work all the time without being affected by a process or the erection of reinforced girders or the like and execute lapping work by a minimum required windine tension by providing a fastening mechanism capable of moving while fastening the outer periphery of a parallel cable near the advancing direction of a winding area. SOLUTION: Near a winding area of a lapping machine in the advancing direction, there is provided a fastening mechanism 52 which is designed to be capable of moving while fastening the outer periphery of a parallel cable 4. While the parallel cable 4 in the lapping area is being throttled with the fastening mechanism 52, wire lapping is carried out with a small void content of a strand of the parallel cable 4, thereby inhibiting the reduction in the fastening tension after the work. It is, therefore, possible to execute lapping work in a similar condition to execute wire lapping of the parallel cable 4 which is subjected to the action of dead load, such as girder load before the erection of reinforced girders in an equivalent condition by throttling the parallel cable 4 in the lapping area.

Filed: 1983-10-25
Abstract: PURPOSE:To ensure the rational hybrid control by using a generalized adverse characteristic arithmetic device which can perform an adverse characteristic operation even in case a transmission characteristic matrix is equal to a rectangular matrix. CONSTITUTION:An analog control system 5 and a digital control system 2 form a multi-point vibration controller. In this case, a generalized adverse characteristic arithmetic device 2d is used as a component element of a digital computer 2. A characteristic acquisition device 2b obtains the characteristics between an input 4 and an output 6 of the system 5 by means of a trial vibration of a random wave.
