Title: Data recording/reproducing device
Inventor: NEGISHI RYUICHI
IPC: G11B21/10
Filed: 1988-05-06
Abstract: PURPOSE:To prevent read errors and data destruction of an adjacent track by detecting acceleration due to an impact and injecting it into a tracking servo loop system. CONSTITUTION:The acceleration due to an impact is detected by an acceleration sensor 15, and its detected output is injected into an adding circuit 16 in the tracking servo loop system, so that a head carriage is controlled in its movement via a linear motor 10. Consequently, even when the data recording/ reproducing device is moved by the impact, the head carriage is moved by the same amt. in the same direction, so that the relative movement of the head carriage against the device is eliminated, thus preventing data of an adjacent track from being destroyed upon execution of read error or write.

Title: Current limiter
Inventor: OKAMOTO MASARU
IPC: H01L39/16
Filed: 1988-05-06
Abstract: PURPOSE:To improve the cooling efficiency of a current limit element and to enable short time duty and high speed reclose by passing superconducting wires through holes made through a board with interval then securing the superconducting wires. CONSTITUTION:Superconducting wires 1 constituting current limit elements are passed through a board 2 and fixed. Holes are made through the board 2 with interval in order to provide a space, between the superconducting wires 1, for passing refrigerant necessary for high speed reclose. By such arrangement, cooling speed is improved remarkably during current limit operation and the temperature rise of the current limit element is prevented, resulting in a short time duty end high speed reclose.

Title: Compounding of paste resin whereby a large amount of filler can be incorporated
Inventor: ISHIKAWA YOSHIO
IPC: C08J3/20
Filed: 1983-06-17
Abstract: PURPOSE:To make it possible to incorporate a large amount of a filler and to obtain a molding at a low cost, by adding water, a surfactant and a fatty acid in compounding a paste resin with at least a plasticizer, a filler and a stabilizer. CONSTITUTION:When a paste resin (e.g., vinyl chloride paste resin) is compounded with at least a plasticizer, a filler and a stabilizer, water, a surfactant and a fatty acid are further added. It becomes possible to incorporate a large amount of a filler and, therefore, it is possible to obtain a molding at a low cost. Conventionally, it has not been possible to incorporate a filler in an amount exceeding that of a paste resin because of an adverse effect on strength and flexibility. Therefore, there has been a problem of high cost. The addition of water, a surfactant and a fatty acid makes it possible to incorporate a filler in an amount about five times that of a paste resin and to reduce the cost to 1/10.
