Abstract: PURPOSE: To obtain a heat resistant steel superior to 18-8 stainless steel in both corrosion resistance and strength at high temp. by using N in place of Ni for maintaining austenite phase when the amount of Cr is increased and by combinedly adding Al and Mg.  
     CONSTITUTION: This steel consists of 0.01W0.20% C, ≤3%, Si, ≤10% Mn, 20W 35% Cr, 10W45% Ni, 0.04W0.25% N, 0.01W0.5% Al, 0.001W0.05% Mg and the balance Fe with inevitable impurities. It may further contain 0.01W1.0% in total of one or more among 0.01W0.5% Ti, 0.01W1.0% Nb and 0.01W1.0% V, and/or 0.001W0.03% B and/or 0.005W0.30% Zr. The lower limit or more of N is required to produce an effect of improving the strength at high temp., yet more  than the upper limit of N does not enhance the effect and exerts unfavorable influence on the toughness after aging. The lower limit or more of Al is required to produce an effect of increasing the strength, ductility and toughness at high temp., yet when the Al content exceeds the upper limit, the effect is not improved furthermore. Mg improves the ductility and toughness, yet excess Mg deteriorates the workability.

Title: Layout compiling method and design system
Inventor: WIN K RUK
IPC: G06F17/50
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To perform compilation to integrated logic and a DRAM system on a single chip from the hardware description language and wiring description of design composed of a DRAM macro and a logic macro by integrating logic and a DRAM memory to the same chip. SOLUTION: From a single processor memory chip for which a processor 21 is connected to a DRAM 22 by on-chip mutual connection 23, off-chip mutual connection disappears. Thus, by DRAM I/O and internal control, a memory data transfer rate utilizable for the processor 21 is raised for many digits. By integrating the processor 21 and the DRAM 22 to the same chip, the length of the on-chip mutual connection 23 and a capacitive load are substantially reduced and optimization is performed further by making the length of a wire shortest. As a result, a system clock speed is accelerated further and performance is improved.

Abstract: PURPOSE:To uniformize a width-wise thickness of an object to be treated which is transferred being sandwiched between an endless belt and a cylinder body by forming a groove on either or both of the sheet-shaped endless belt and the cylinder body. CONSTITUTION:A concave groove 10 is formed on the surface of an endless belt 6 beforehand. When an object 4 to be treated rolled to a almost fixed thickness with a pressure roll is pinched with the endless belt 6, it enters the concave groove 10 in the surface of the belt 6 to be pressed onto the surface of a cylinder body 1 and is transferred to be heated or cooled as it is and hence, a shape of a section of the object to be treated as given during the pressing thereof onto the cylinder body 1 with the endless belt coincides with the shape of the section of the concave groove 10. As a result, when the concave groove 10 is formed in such a manner that a depth thereof is constant across the width thereof, the thickness of the object 4 to be treated becomes even across the width thereof. The object 4 to be treated receives a cooling or heating action from the surface of the cylinder body 1 while being transferred and finally, it is cooled or heated down or up to a specified temperature.

Title: High-frequency heating system

IPC: F24C7/08
Filed: 1979-04-24
Abstract: PURPOSE: To simplify setting of the content of heating process, by employing an arrangement in which each time period required for combined heating of high- frequency heating and grille heating can be determined at a required ratio for a fixed time period by once setting the heating time.  
     CONSTITUTION: When a high-frequency heating switch 4-c is turned ON, the content is stored in RAM 1-3 by means of ROM 1-2 of a microcomputor 1. Subsequently, When heating time (t) is set through manipulation of two knobs of a digital value varying means, each time period required for both of high-frequency heating and grille heating is determined at a required ratio. For instance, time periods (t) and (0.8t) are stored in RAM and indicated at 5 in the drawing. When a "heating" starting switch 4-3 is then turned ON, high-frequency generating means 7 is set into operation, and at the same time, subtraction of time (t) is started by counting the time pulses from a pulse generating circuit 3. When the result becomes zero, the process of high-frequency heating is stopped. Thereafter the heater 8 is set into operation, and subtraction of time (0.8t) is started in the same way. The operation of the heater 8 is stopped when the result of subtraction becomes zero.

Title: Fine movement device
Inventor: MIYATA CHIKAYOSHI
IPC: G01B7/34
Filed: 1988-03-03
Abstract: PURPOSE:To reduce interference in a Z-axis due to in-plane driving without increasing wiring and an in-plane driving power source in a device by a method wherein the poling direction of electrodes facing each other among four or two split electrodes for in-plane scanning is reversed and push-pull operation is performed by applying the same signal. CONSTITUTION:After a cylinder is made of piezoelectric material, an electrode is attached to the outer wall and an inner electrode G is attached to the inner wall. The voltage is applied across the inner electrode G and outer electrode with the temperature of the cylinder made of a piezoelectric material raised to the Curie point, and processing (poling) for aligning the direction of piezoelectric particles is carried out. In this poling, the poling directions of facing electrodes are changed by reversing the direction for applying voltage between X and X' and between Y and Y', with respect to the four split electrodes X, Y, X' and Y'. By applying X-axis driving voltage both to X and X', and applying Y-axis driving voltage both to Y and Y', push-pull driving can be carried out on this fine movement device. In other words, when an equal voltage is applied to X and X', the X' electrode part shrinks if the X electrode part extends, so that the respective electrodes extend and shrink in a reverse direction to each other. This prevents a probe 1 from moving vertically even though in-plane driving is carried out so that interference in the direction of the Z-axis (DELTA=0) can be suppressed.
