Title: Elbow/bend pipe, manufacture thereof, and manufacturing device therefor
Inventor: MIYAZAKI KATSUMASA
IPC: F16L9/00
Filed: 1998-06-15
Abstract: PROBLEM TO BE SOLVED: To lower a speed of internal fluid colliding against an inside surface wall in the outside radius part in a bent part of a bend pipe such as an elbow pipe so as to suppress generation of erosion or corrosion by forming a cross section shape of the bend pipe into a specific elliptic shape. SOLUTION: In an elbow/bend pipe 11 in a plant piping system, a cross section of the pipe 11 is formed into a shape in which an axis of a plane including the inside diameter and the outside diameter of the bend part serves as a major axis while an axis making an angle of 90 deg. with the major axis serves as a minor axis. Fluid 1 in a pipe flows inward from the lower side and flows outward to the right side through the bend pipe 11. In this case, an axis of the pipe cross section including the outside radius and the inside radius of the bent part in the bend pipe 11 corresponds to a major axis of an ellipse while an axis making an angle of 90 deg. with the major axis in the cross section corresponds to a minor axis of the ellipse. Since the pipe cross section is an elliptic shape, the fluid 11 is smoothly flows inside the pipe 11.  Therefore, the fluid 1 is prevented from directly colliding against the pipe inside wall face in the bend outside radius part.

Title: High manganese non-magnetic steel used at super-low temperature
Inventor: KASAMATSU YUTAKA
IPC: C22C38/16
Filed: 1980-11-26
Abstract: PURPOSE: To obtain a high-strength and non-magnetic steel excellent in the ductility and toughness which can keep the stabilized non-magnetism, by incorporating Cu, N and Al into a high manganese non-magnetic steel.  
     CONSTITUTION: The high manganese non-magnetic steel used at super-low temperatures contains 0.3W1% of C, 12W25% of Mn, 0.5W10% of Ni, 0.5W4% of Cu, 0.001W0.3% of N and 0.001W1% of Al and, if necessary, 3% or more of Mo, 0.3% or more of Nb and 0.3% or more of V, and the balance of Fe and impurities. The Cu reduces the work hardening property, and stabilizes the austenite even at super-low temperatures to remarkably improve the ductility and toughness, and in this respect the amount of thereof should be 0.5% or more, while if the amount exceeds 4%, the hot working properties and resistance to cracking during welding will be worsened. To stabilize the austenite, the amount of N should be equal to the lower limit or more, while the excess amount thereof reduces the resistance to blow hole during welding. The Al serves to clean the impurities and to enhance the toughness, so that the amount thereof should be the lower limit or more, but it is not required to exceed the upper limit.

Title: Monitor control system
Inventor: TAKEUCHI YUTAKA
IPC: G05B23/02
Filed: 1990-06-26
Abstract: PURPOSE:To process a data of state change with a more heavily weighted level caused newly with priority by varying a weight level of a monitor items in response to the frequency of occurrence of the state change in the monitor items of a station to be monitored. CONSTITUTION:When a state change in only a specific monitor item takes place with a high frequency of occurrence, a state change measuring section 16 of a monitor station equipment 11 counts number of times of occurrence of the state change in the monitor item for a prescribed time and reduces the weight level of the monitor items when the count exceeds a predetermined threshold level and informs the result to station devices 21a-21c to be monitored. When number of times of occurrence of the state change reaches the predeter mined threshold level or below after lapse of a prescribed time, the section 16 gives a notice of restoration of the weight level to the station devices 21a-21c to be monitored. Thus, a delay in data processing of a state change with a, more heavily weighted level caused newly due to the data processing of state change information with a comparatively lighter weighting level caused at a high frequency of occurrence is avoided.

Title: Semiconductor light-emitting element
Inventor: TANAKA TOSHIAKI
IPC: H01S5/00
Filed: 1984-08-10
Abstract: PURPOSE:To discriminate the projection side and reverse side of laser beams easily, to improve yield and to enable the avoidance, etc. of dispersions among pellets by forming electrodes on at least one surface in patterns having different shapes on the projection end surface side and reverse end surface side of light-beams. CONSTITUTION:The N type electrode side is formed through a photoetching method as repeated pattern 32, 33, which are sufficiently finer than pellet width W and have mutually different shapes, in the direction orthogonal to the stripe direction. A cleavage is conducted from the N type electrode side by using the pattern 32. Consequently, an N-side electrode is formed in structure of patterns 34, 35 each different on the projection end surface side and reverse end surface side of light-beams, thus allowing work while a projection surface and a reverse surface having different coating-film thickness are discriminated easily through visual observation when the semiconductor layer is mounted to a heat sink, etc. while the surface of the N type electrode is directed upward. Accordingly, workability and yield are improved while the displacement of the electrode patterns can be avoided, thus obtaining an element having high reliability.

Title: Overhead projector with copying function
Inventor: NOGUCHI MATSUSABURO
IPC: H04N1/00
Filed: 1987-07-07
Abstract: PURPOSE:To project an image in a home position all the time, to write a new image by viewing a projected image, to erase an image by viewing the projected image and to quickly return the image having been projected by traveling and stopping a writing medium sheet where images about characters, symbols, graphics, etc., are stated in one-page units. CONSTITUTION:When a page mark sensor 35 detects a page mark and outputs it to a control circuit part, said part stops a motor. Since writing-in range marks agree with four corners of a Fresnel lens 25, projected light beams 45 from a light source 3c hit a reflecting member 26, which reflects said beams. Reflected light beams 46 transmit the Fresnel lens 25 and the writing-in range marks on the writing medium sheet 1, and get to a screen 31 through a projecting lens 3b and a magnifying glass 2 for projecting, thereby projecting an image. When a return mode button is pressed, the control circuit part drives the motor, and the sheet 7 travels by one page, then stops. In case of copying, when a prescribed button is pressed, the writing medium sheet 7 begins to travel, while the control circuit part begins to copy.
