Title: High strength valve spring and its manufacture
Inventor: AOKI TOSHINORI
IPC: C22C38/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide a valve spring having fatigue resistance, settling resistance, and delayed fracture resistance which are more improved than those of the conventional one by selecting an optimum stock and properly combining subsequent spring manufacturing stages. SOLUTION: A steel, which has a composition containing, by weight 0.5-0.8% C, 1.2-2.5% Si, 0.4-0.8% Mn, 0.7-1.0% Cr, <=0.005% Al, and <=0.005% Ti and in which the maximum nonmetallic inclusion is regulated to 15 μm, is used as a stock. At the time of oil tempering treatment, hardening temperature is regulated to 950 to 1,100 deg.C. After coiling, nitriding treatment is applied. It is desirable to perform this nitriding treatment at a temperature as high as >=480 deg.C. Since the high silicon steel is used as a stock, tempering temperature can be raised and such a high temperature nitriding treatment is made possible. By this method, high surface hardness can be obtained, and fatigue resistance, settling resistance, and delayed fracture resistance can be improved.

Title: Fiber type light amplifier
IPC: H04B10/032
Filed: 1992-03-23
Abstract: PURPOSE:To prevent a fiber type light amplifier from deteriorating sharply in gain even if one of two pumping light sources deteriorates by a method wherein an optical output control means controls the other pumping light source in output so as to enhance it in output when a deterioration judging means detects that a pumping light source deteriorates. CONSTITUTION:For instance, if a pumping light source 2b deteriorates in optical output to be less than a certain value, a deterioration judging circuit B 8b outputs deterioration detection signals to an optical output control circuit A 9a when the output current of a photodetector B 7b becomes smaller than a prescribed judgement value. An optical output control circuit A 9a enables an pumping light source 2a to increase in output by a prescribed value basing on a deterioration detection signal b so as to make the optical output of the pumping light source 2a small in passage gain change to signal light. By this setup, a fiber type light amplifier of this design can be prevented from deteriorating sharply in gain as a whole even if either of two pumping light sources deteriorates.
