Title: Method for evaluating development speed of fatigue cracking of steel material
Inventor: YODA NOBORU
IPC: G01N3/32
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To quickly and efficiently evaluate a fatigue cracking development speed of a steel material by finding a softening amount when a steel material wherein bainite is contained in a texture by at least a specified percentage is applied with the repeated load of distortion control with a both-sided waveform at a stress ratio in a specified range. SOLUTION: The softening amount when a steel material wherein at least 20% of bainite is contained in the texture is applied with a repeated load of both-sided waveform for distortion control at a stress ratio from -4 to -0.25, preferably from -2 to -0.5, is measured with a stress or hardness as an index, for evaluating a fatigue cracking development speed based on that. Here, the stress ratio is a value for a distortion which is the control amount for a load waveform which is provided by dividing a minimum distortion value with a maximum distortion value. The steel material should contain bainite by at least 20% in the texture, with regard to other texture than bainite, anyone including ferrite, perlite, martensite, austenite, etc., is allowed as remaining portion.  The distortion waveform applied on the steel material should be a both-sided waveform where tension and compression are alternated from evaluating the repeated softening amount of the steel material.

Title: Pressure controlling method and device in etching equipment
Inventor: NISHIHATA KOJI
IPC: H01L21/302
Filed: 1986-09-10
Abstract: PURPOSE:To maintain a process pressure inside a vacuum chamber in a plasma discharging operation so as to be a definite one, by starting discharge when the pressure inside the vacuum container attains within the range of an etching process pressure and measuring the pressure inside the vacuum container after the discharge and performing a PID control of a variable valve. CONSTITUTION:A variable valve 7 and a valve 10 are opened and a vacuum pump 11 is operated to perform vacuum exhaustion inside a vacuum container 1. When the pressure inside the container 1 attains to a definite pressure, valves 2 and 5 are opened and a flow rate controller 3 is controlled to supply a proper quantity of process gas into the container 1 from a process gas supplying source. Discharge is generated inside the container 1 by the use of a high-frequency power source 13. The pressure inside the container 1 is made feedback and PID control is performed inside a controller 15 to adjust an opening degree of a valve 7. If the pressure inside the container 1 is in the allowable range, the opening degree of the valve 7 is memorized. Hence, the process pressure inside the container 1 is maintained to be a definite one.

Inventor: AWANO HIROYUKI
IPC: G11B7/24035
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium suitable for ultra high density recording by high AN lens. SOLUTION: This optical recording medium 10 has a thermal conductive layer 2, a reproducing layer 3, a recording layer 4 and a lubricating agent layer 5 sequentially on one surface of a substrate 1. As the substrate 1, a thinly shaped flexible substrate having <0.6 mm, preferably 50 μm-500 μm thickness is used. Therefore, the interval between a lens and the recording layer can be shortened. Accordingly, a slight optical spot can be formed on the recording layer 4 by utilizing a high AN lens having a short focal distance. Heat generated in the recording layer 4 or the reproducing layer 3 can be satisfactorily diffused at an optical incident side by the thermal conductive layer 2 having high thermal conductivity. Therefore, ultra high density recording of information and reproduction of the ultra high density recorded information can be realized.  This optical recording medium is quite suitable for an optical recording medium in the coming generation.

Abstract: PURPOSE:To prevent optical backlash by stopping a motor at the time of completing the retreat of a photographic lens, connecting a zoom changeover switch in neutral and driving the motor for a short time again in the case that optical hysteresis occurs at the time of retreating the photographic lens to a wide side. CONSTITUTION:The title camera is provided with zooming devices 51 and 52 which switch a power transmitting path by using clutch means 50b and 50c and make the photographic lens 54 advance and retreat in virtue of the rotation in the same direction of one motor 30 to change a focal distance. When the changeover switch 66 for moving the lens 54 in a direction where the optical hysteresis occurs is disconnected in the case of making the photographic lens 54 advance or retreat in virtue of the rotation of the motor 30, a contact disconnection signal is transmitted and the rotation of the motor 30 is stopped with the contact disconnection signal. Thereafter, the motor 30 is allowed to rotate for a specified time in the case of connecting the changeover switch 66 to a neutral contact. Thus, the backlash caused by the optical hysteresis can be surely eliminated with a simple means.
