Title: Rotary transformer
Inventor: INOUE HIROTO
IPC: H01F38/14
Filed: 1986-04-23
Abstract: PURPOSE:To lower a crosstalk, and to deliver stable transmission signal by covering the surface on the side having at least winding grooves of a base material with a plurality of concentric ring-shaped winding grooves, forming magnetic films divided and shaped at every plural winding groove and inserting coils to the winding grooves. CONSTITUTION:R side magnetic films 3a and S side magnetic films 3b are shaped so that the rotary side is brought to Tr and the stationary side to Ts in thickness so as to be divided and formed at every plural winding groove, covering the side on which at least grooves of the rotary (R) side and stationary (S) side base materials are formed. R side coils 5a, 5b, 5c are fitted to a plurality of R side winding grooves 7a snd S side coils 5d, 5e, 5f to a plurality of S side winding grooves 7b. When currents flow through the R side coil 5b at that time, a magnetic flux generated shapes a magnetic path 9a along the magnetic film, and only extremely slight magnetic flux is caused to flow through a magnetic path 9b by air gaps 2a, 2b, thus inducing large currents in the S side coil 5e, then inducing only extermely slight currents in the S side coils 5d, 5f. Accordingly, a crosstalk can be lowered.

Title: Protection of rocky slope
Inventor: NAKAMURA RYUHEI
IPC: E02D17/20
Filed: 1987-04-15
Abstract: PURPOSE:To form a very dense covering layer by a method in which a mixture of synthetic resin emulsion and alkali-resistant glass fibers is mixed with cement and aggregate, sent under pressure, and sprayed onto rocky slope by spray pump, etc. CONSTITUTION:A covering layer 2 is formed on rocky slope 1 by spraying a mixture of cement, aggregate, alkali-resistant glass fibers 3, and a synthetic resin emulsion onto the slope 1 while mixing it with stirring by a pressure sending pump. The delaminating and falling-down of the covering layer 2 by freezing of permeated water can be prevented because the impact resistance of the layer 2 becomes ten times cement mortar. Since the cement is gelled naturally, the occurrence of cracks by the binding action of the fibers can be prevented.
