Title: Insulation block at cable joint
Inventor: ANDO KOJU
IPC: H02G15/08
Filed: 1995-02-14
Abstract: PURPOSE: To prevent an insulation block from being damaged easily at the time of handling or the like and a foreign matter from adhering thereto by previously covering the outer circumferential surface of the insulation block with a semiconductive and thermally shrinking protective film in order to utilize a semiconductive layer as a protective film. CONSTITUTION: A tubular electrode member 12 is embedded coaxially in the center of a tubular insulation block 10 having outer circumferential face covered entirely with a tubular protective film 14. The tubular protective film 14 is made by stretching crosslinked polyethylene containing a conductive material, i.e., carbon, tubularly and has semiconductive and thermally shrinking properties. With such structure, the body of the insulation block 10 is not damaged and a foreign matter does not adhere thereto when the insulation block 10 is stocked, transported to a site or handled thus facilitating the handling greatly. Furthermore, inspection work can be eliminated at the time of crosslinking.

Title: Photographing mode changing-over device for video camera
Inventor: YOSHINUMA KATSUMI
IPC: H04N5/225
Filed: 1986-03-06
Abstract: PURPOSE:To save a space and to improve an operability by using one picture recording control switch, executing the frame photographing by turning the switch on in a moment and executing the continuous photographing by continuing to turn the switch on. CONSTITUTION:At the time of a frame photographing mode, when a picture recording control switch SW is turned on for a T0 time, the electric potential of the E terminal of a picture recording control circuit REC comes to be from a high H to a low L for the T0 time only, and the REC starts to travel a tape by the fall signal. Simultaneously, a rise signal is supplied to an input terminal B1 of a changing-over signal generating circuit CSO. An IC1 of the CSO receives the input, generates an H output of the time width of a T1, and by receiving this input, an IC2 generates the H output of the time when of a T2. A transistor TR receives the input, decreases the electric potential of an E terminal and the REC stops the traveling of a tape by the fall signal. When an SW continues to turn on at the time of a continuous photographing mode, the REC starts the traveling of the tape by the fall signal at the time of ON. Even when the SW is turned off after a T1 time passes, photographing is continued, and next, by the fall signal generated when the SW is turned on, the tape is stopped.

Title: Waterproof finishing method of hardened concrete surface
Inventor: YAMADA SHIGEYUKI
IPC: C04B41/71
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent such a problem that when a concrete body as hardened is repaired, the border between the original body not repaired and the repaired part has a coating appearance, by including a process to apply a waterproof finishing material prepared by mixing a silane water-based emulsion, an acrylate copolymer emulsion and a white pigment on the part of the concrete body surface to be repaired. SOLUTION: The part of the surface of a concrete hardened body to be repaired is subjected, if necessary, to touch-up for defects such as cracks and to base treatment, and then a waterproof finishing material is applied on this part. The waterproof finishing material is prepared by mixing a silane water- based emulsion, for example, by 72.8%, an acrylate copolymer by 24.3%, and a white pigment by 2.9%. If necessary, a fluorocarbon resin is applied all over the surface to increase the waterproof property. As a result, when the concrete body is partly repaired, the repaired part is hardly recognized from the original part not repaired.

Title: Channel preset circuit
Inventor: WAKABAYASHI KOUICHI
IPC: H03J7/18
Filed: 1980-04-18
Abstract: PURPOSE:To operate the circuit accurately and independently of the state of electric field and to make the operation easy, by presetting channel through rise and fall of tuning voltage through the operation of the 1st and 2nd frequency sweep switches. CONSTITUTION:When the channel A is preset, the channel selection button A is first depressed. Then, either one of the frequency sweep switch 5 or 6 is depressed and the tuning voltage is swept toward either high or low direction. Thus, when the broadcast signal of the channel A is started to be received, the IC terminal 18 is at low level with the synchronizing signal applied to the terminal 15 to delay the sweep of the tuning voltage of IC1. In this case, the switch 5 or 6 is released when the state of picture is the best after reaching the normal tuning point to stop the sweep of the tuning voltage. Further, when other channel selection button is depressed, the tuning voltage corresponding to the channel A is stored in the memory IC2. Further, when a channel is skipped, the switch 19 for unnecessary station skip is depressed.

Title: High frequency transmission line
Inventor: TSUZUKI GENICHI
IPC: H01L39/24
Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To reduce the transmission loss of a microwave/millimeter wave transmission line and various passive circuit devices by forming an edge part of a conductor tangent to a dielectric board round. SOLUTION: Both sides of ridges 10a, 10b of a strip conductor 10 with a prescribed width formed on one side of a dielectric board 1 are finished round. In this case, only parts in contact with the dielectric board 1 are to be formed round. Since the ridges 10a, 10b of the strip conductor 10 are finished round, the electric field having been concentrated on the ridges in a conventional line is distributed onto the surfaces of the ridges 10a, 10b. Since the current density of the ridges 10a, 10b is reduced, a defect caused in the case of using, e.g. a superconducting material for a material of the strip conductor to reduce considerably the transmission loss is avoided.
