Title: Ant repellent wire-cable
Inventor: YAMAGAI YOSHIHISA
IPC: H01B7/28
Filed: 1990-07-16
Abstract: PURPOSE:To improve flexibility, shock-proofness and workability of an ant repellent layer while holding high and-repellance by forming the ant repellent layer of nylon elastomer having specific Shore D hardness. CONSTITUTION:A conductor 1 is in turn coated with an insulator 2 and a sheath 3 while coating the periphery of the sheath 3 with nylon elastomer, to form an ant proof layer 4. At this time, the nylon elastomer having a 5-sec value of Shore D hardness not less than 50 at a measurement temperature 20 deg.C is selectively used. Accordingly, nylon elastomer of the ant proof layer 4 is high in mechanical strength and hardness and moreover its surface is smooth, hard and slippery, therefore ants are difficult to bite it. Thereby, a high ant repellance can be obtained while having good flexibility and excellent shock- proofness and causing no breaking of the ant proof layer even if a shock of a falling object or the like is applied, and moreover handling at the time of winding is improved.

Title: Roll forming device
Inventor: TSUKAMOTO EIHIKO
IPC: B21H7/00
Filed: 1981-11-24
Abstract: PURPOSE:To roll form and cut members such as cooling fins etc. in one process by cutting grooves of different pitches on upper and lower forming rolls arranged opposite to each other and rotating the rolls at specified peripheral speed ratio. CONSTITUTION:Grooves different in pitch by respective rolls are cut on the outer peripheries of a pair of forming rolls 11, 12 and passes of different shape are formed. A plate material 1 is inserted between upper and lower rolls 11, 12, and upper and lower rolls 11, 12 are rotated with different peripheral speed. Corresponding position of upper and lower passes are placed at corresponding position of upper and lower rolls 11, 12. When the plate 1 is bitten, positions of corresponding passes are deviated. However, with the lapse of time, distance between the passes becomes smaller, and phases of the passes become coincident. Then, phases become deviated and distance between the passes becomes larger. Because of the difference in peripheral speeds between upper and lower rolls 11, 12, shearing is generated in the material 1, and the material is torn off at the parallel joint part of the passes. Thus, cutting is completed simultaneously with forming of fins.

Title: Oxygen scavenger and its production
Inventor: WATANABE HARUO
IPC: H01F1/26
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To reutilize a used magnetic recording medium or a waste material of a magnetic recording medium to reduce environmental load by using the magnetic layer forming matter separated from the magnetic recording medium wherein a magnetic layer based on a ferromagnetic metal powder and a binder is formed on a base material as an oxygen scavenger. SOLUTION: The so-called coating type magnetic recording medium obtained by forming a magnetic layer based on a ferromagnetic metal powder and a binder on a base material (base film) composed of polyethylene terephthalate is subjected to separation treatment to obtain a magnetic layer forming matter which is, in turn, reutilized as an oxygen scavenger. In this case, when an electrolyte is held to the magnetic layer forming matter, ions of the electrolyte act so as to accelerate the oxidation of the metal magnetic powder and, as a result, oxygen scavenging activity is enhanced. When a hydrous polymeric material is held to the magnetic layer forming matter, moisture contained therein or the hydrous polymeric material has the support effect of the electrolyte and, therefore, the oxygen scavenging effect of the magnetic layer forming matter is enhanced.
