Title: Optical fiber low temperature sensor
Inventor: SANADA HIROYUKI
IPC: G02B6/44
Filed: 1992-09-25
Abstract: PURPOSE:To easily and accurately detect temperature drop by employing a coating material having specific residual shrinkage for the core of an optical fiber. CONSTITUTION:The optical fiber low temperature sensor 1 comprises an optical fiber 2 core coated with a material 3 having residual shrinkage of 0.6% or above. When the temperature drops below a specified level due to abnormality of a temperature conditioner, the thermal shrinkage member 3 shrinks to apply external force having high side pressure to the fiber 2 which is thereby subjected to microbending. Consequently, transmission loss of the fiber 2 increases abruptly. A light emitter delivers an optical signal from one end of the fiber 2 and the intensity of the optical signal is measured at the other end of the fiber 2 thus attaining measurement data representative of the extent of room temperature drop. When the material of the member 3 is changed, thermal shrinkage thereof varies thus allowing arbitrary setting of detecting temperature.

Title: Engine valve and its manufacture
Inventor: HAMADA AKIHIRO
IPC: F01L3/24
Filed: 1994-10-21
Abstract: PURPOSE: To enhance abrasion resistance, and reduce cost in manufacture by forming a hardened layer in a dendrite texture structure whose crystal orientation is directed to its face surface from the inside of base material in a valve face section. CONSTITUTION: A hardened layer in a dendrite texture structure whose crystal orientation is directed to its face surface from the inside of base material is formed in the surface of a valve face section 2a formed in an umbrella section 2. Carbide and nitride are distributed in the dendrite texture structure. The surface of the valve face section 2a is locally heated at a temperature in excess of the melting point of valve material so as to be fused. Since the locally heated valve face section 2a is forcibly cooled in order from the umbrella section side by a work pedestal which has been cooled by cooling water, it is formed into a texture structure where crystal orientation is extended in a dendrite shape to the direction of its face surface.  Since abrasion resistance can thereby be enhanced at its valve face section with no padding made, no expensive hard metal is required, and an inexpensive engine valve can thereby be obtained.
