Title: Production of ti-containing hot dipped steel sheet
Inventor: FUKUI YASUSHI
IPC: C23C2/40
Filed: 1993-02-15
Abstract: PURPOSE:To improve the corrosion resistance and heat resistance of a plated steel sheet by forming a multilayer plating layer containing relatively large amounts of Ti in a second layer. CONSTITUTION:A course of stages, consisting of activation treatment by plasma etching or ion beam etching, vacuum deposition of Ti, and hot dip Al-Si alloy coating, is done in the same vacuum tank. On a substrate steel S, a second layer L2 of Al-Ti-Si-Fe type, excellent in corrosion resistance, is formed between a first layer L1 of Al-Si-Fe-Ti type and a third layer L3 of Al-Si-Ti type. It is preferable to regulate Ti concentration in the second layer L to >=0.5wt.%. Further, Ti in the second layer L2 is supplied from a Ti coating layer formed by means of vacuum deposition on a starting sheet for plating prior to immersion in a hot dipping bath. By this method, the corrosion resistance and heat resistance of the plated steel sheet can remarkably be improved by means of the second layer L2 and the third layer L3, and corrosion resistance equal to that of stainless steel can be obtained at a low cost even in the case where inexpensive plain steel is used as a starting sheet for plating.

Title: Coupling device for optical parts
Inventor: SEMURA SHIGERU
IPC: G02B6/26
Filed: 1992-03-06
Abstract: PURPOSE:To provide the coupling device which decreases the laborious operations to enhance coupling efficiency in coupling of optical parts using a polarizer and executes the coupling without adjustment. CONSTITUTION:The polarizer 20 is formed on the plane in the central part of a silicon substrate 1. A guide groove 3 for a laser and guide groove 4 for an optical fiber which are aligned in optical axes are constituted on the same substrate 1 by holding the polarizer 20 therebetween. A guide 5 for the laser installed with a semiconductor laser and the optical fiber 6 are disposed in the respective guide grooves 3, 4. As a result, the positions of the guide 5 for the laser and the optical fiber 6 are fixed by the respective guide grooves 3, 4 and since the polarizer 20 is integrally formed on the substrate 1, there is no need for aligning the optical axes and adjusting the incident angle of light on the polarizer with high accuracy. The coupling losses are thus suppressed and the coupling with high efficiency at an increased extinction ratio is executed. Since the mechanical strength is high and the mis-registration after fixing is hardly generated, the deterioration in the coupling efficiency is prevented and the high reliability is obtd.

Title: Diagnostics for accident of check valve with valve operating device
Inventor: IMAIZUMI TATSUO
IPC: F16K15/18
Filed: 1980-04-17
Abstract: PURPOSE: To enable an abnormality of valve operation to be detected by a deviation value between a normal data and the data which is corrected to a valve opening corresponding to the prescribed dynamic pressure through the valve opening or the dynamic pressure obtained during an operation test and processed as a function of time.  
     CONSTITUTION: It is judged to be abnormal if the ratio of the normal value a 1  to an observed value b 1  or the difference therebetween is found to be larger than the prescribed value as the result of comparison of change rates of a valve opening obtained during an operation test. It is also judged to be abnormal if the result of comparison of valve operation after resetting the valve implies that the observed data shows the valve opening changing monotonously along a dotted line B while the normal data shows generation of a little damped oscillation. Moreover, because the valve opening changes in such a form of steps as shown with one dotted chain line C if the valve operation is not smooth, any abnormal londition may be judged through comparison of a change pattern of the valve opening from the start of the operation test to resetting as well as comparison of patterns after resetting.

The calculated delay is more accurate than when the gate delay is calculated by using the temporary input waveform rounding found in S204. Further, the gate delay is calculated by using a table look-up system, so the gate delay can accurately be calculated fast. Then wiring delay twire found in S207 and tpd found in S210 are added to find the propagation delay time from the supply of an input to one unit circuit to the variation of its output.
