Title: Reversing device of tape
Inventor: NEMOTO HISASHI
IPC: G11B15/087
Filed: 1984-02-01
Abstract: PURPOSE:To reverse assuredly a magnetic tape always at a fixed position without heat influence of external light by detecting a leader part of the magnetic tape on the basis of a reproducing noise difference and reversing the tape. CONSTITUTION:When the leader part of the magnetic tape reaches the opposite position of the rotary head 3, the reproducing noise level by the head 3 is reduced less than the reproducing noise level of a magnetic part. Consequently, the charging voltage of a capacitor 15 is reduced, a Zener diode 17 is turned off and a transistor 18 is also turned off. The leader part detecting output inverted to the low level is applied to a microcomputer 9 and the tape is reversed through a mechanical part control circuit 10. Said mechanism makes it possible to detect assuredly the leader part without heat influence of external light and reverse the tape always at the fixed position near the border between the magnetic part and the leader part.

Title: Measuring device for temperature
Inventor: WADA ICHIROU
IPC: G01K11/12
Filed: 1980-02-11
Abstract: PURPOSE:To measure temperature highly precisely with a simple constitution by performing the measurement of temperature by utilizing a fact that refractive index of a substance changes according to temperature. CONSTITUTION:A light projected by a projector 11 passes through an optical fiber 13 and is reflected by a rotating mirror 20 and scanned in the direction of an arrow A. And, when it is reflected by the 1st reflecting mirror 211, it passes through the same optical path and is reflected by a semitransmitting mirror 14, transduced into an electric signal by a photoreceptor 15 and turned to be a starting signal for a counter and the like as a reference signal. Meanwhile, the light scanned in the direction of an arrow A' enters a prism 23a, undergoes total internal reflection on the interface with the substance 23b while the incident angle alpha is of a prescribed size, is reflected by a reflector 24, and, passing through the same optical path, is received by the photoreceptor 15. When the incident angle alpha becomes smaller than a prescribed value, the light entering the prism 23a transmits through the substance 23b. Since the refractive index of the prism 23a changes when the temperature thereof changes, the temperature can be known from a time until a reflected light becomes absent at the photoreceptor 15.

Title: Brake disk made of aluminum alloy
Inventor: TAKIGAWA HIROSHI
IPC: C23C4/08
Filed: 1988-01-28
Abstract: PURPOSE:To improve the adhesive strength and wear resistance of a stainless steel film by forming the film of stainless steel on the plane part of a discoid Al alloy under reduced pressure by means of plasma thermal spraying. CONSTITUTION:Stainless steel powder is plasma-sprayed under reduced pressure on the plane part (a plane to be in contact with a brake pad) of an Al alloy previously formed into a discoid state, by which a film of the stainless steel is formed. By this method, porosity is lowered because contamination with air is prevented, and, as a result, a dense film layer can be formed. Further, since the presence of oxide as a mixture can be prevented, high adhesive strength can be obtained at the boundary between a brake disk body and the film. Accordingly, a brake disk made of Al alloy lightened in weight, having superior corrosion resistance and wear resistance, and excellent in adhesive strength can be provided.
