Patent JP-S6110269-A (JP)
Title: Semiconductor ic
Inventor: HASHISHITA RIYUUICHI
IPC: H01L21/8238
Filed: 1984-06-26
Abstract: PURPOSE:To diminish the delay of propagation of signals due to high-resistant wiring by reducing the wiring area by a method wherein power source lines and signals lines are made rectangular to a P type transistor assembly region band and an N type transistor assembly region band parallel thereto, and propagation directions of signal processing are made parallel. CONSTITUTION:The region surrounded by a one-dot chain line parallel with the P type MOS transistor assembly region band 1 which is the region surrounded by a dot line is made as the N type MOS transistor assembly region band 2. Power source lines V1 and V2 and input signal lines IN1, IN2, IN3, and IN4 all use metallic wirings and designed so as to be rectangular to the P type MOS transistor assembly region band 1 and the N type transistor assembly region band 2. Signal processing is propagated from left to right as shown by an arrow F, and the propagation is parallel with the bands 1 and 2. This enables the incorporation of input signals into element regions without crossing the power source lines, and therefore without change-over to other wirings of poly Si and the like.

Inventor: KURODA AKIHIRO
IPC: C22C21/00
Filed: 1994-05-20
Abstract: PURPOSE:To produce a rocker arm having a light weight, high strength, high modulus of elasticity, etc., by adding Al material powder to the precursor composite of respective constituting alloy element powders of intermetallic compds. and subjecting the mixture to mechanical ironing, then subjecting the mixture to molding and degassing, putting the mixture into metal molds and subjecting the mixture to hot forging at a specific temp. CONSTITUTION:The powders of the respective constituting alloy element of the intermetallic compds. which are reinforcing particles are weighed and mixed according to a stoichiometric compsn. and the mixture is subjected to mechanical ironing by using a high energy type attriter, by which the precursor composite of the intermetallic compds. is formed. A prescribed amt. of the Al powder or Al alloy powder is charged into this precursor composite and the mixture is again subjected to the mechanical ironing and, thereafter, the mixture is classified. The powder of about <=150 meshes is compressed in the metal molds to form a preform. This preform is subjected to degassing. The preform subjected to the degassing treatment is set in the metal molds and is hot forged at 400 to 500 deg.C to bring the precursor composite dispersed in the Al matrix to form the intermetallic compds. The molded goods formed in such a manner are machined, by which the rocker arm is produced.

Title: Production of gradient gel film for electrophoresis
Inventor: TERAI FUMITAKA
IPC: G01N27/447
Filed: 1987-05-29
Abstract: PURPOSE:To produce a titled film with good stability and reproducibility by supplying a coating liquid while expanding the liquid continuously in a transverse direction and reducing the same continuously in a thickness direction from the supplying port of a coating head up to a slot aperture. CONSTITUTION:The coating liquid to be supplied from the supplying port 14 to the slot 16 needs to be continuously expanded and reduced in both the width and thickness and the angles of the expansion and reduction need to be made as relatively gentle as possible and, therefore, the length of the slot 16 of the coating head necessitates the larger length than the length of the conventional slot. The coating head 8 is, therefore, disposed in the position shown in the figure with respect to a coating roller 20. The angle alpha of the reduction in the thickness direction is preferably smaller than 35 deg. and the size in the transverse direction of the slot 16 is continuously widened to, preferably a Venturi type from the coating liquid 12 supplying port 14 of the coating head 8 to the slot aperture 17. The gradient gel film for electrophoresis having an exact concn. gradient and the good stability and reproducibility is thereby produced with good productivity.

Title: Double-discharge nozzle box of steam turbine
Inventor: KIRIKAMI SEIICHI
IPC: F01D9/02
Filed: 1978-10-27
Abstract: PURPOSE: To protect inner surface of a double-discharge nozzle box of steam turbine against damage due to fine liquid particles, by shaping the inner surface of nozzle box with substantially uniform flat surface and to keep the distance between the inner surface and the outer peripheral surface of rotor substantially constant.  
     CONSTITUTION: If fine liquid particles contained in steam are accelerated by their contact with the outer peripheral surface of rotor 12 and blown off toward nozzle box 11, they are made to flow gradually along the streamline of circumferential steam flow since distance L between inner surface 11c of the nozzle box 11 and the outer peripheral surface of rotor 12 is substantially constant and fairly large. Therefore, collision energy of the liquid particles in the direction perpendicular to the inner surface 11c is reduced so that the inner surface 11c is not subjected to erosion almost at all. Further, velocity of the liquid particles is reduced considerably by the time when they reach the inner surface 11c since boundary layer exists over the inner surface 11c, so that inner surface 11c of nozzle box 11 can be protected against damage almost completely.

Filed: 1995-05-30
Abstract: PURPOSE: To drive a shake correction mechanism in exact timing by deciding the starting timing of the shake correction mechanism, based on shake information at the time before starting exposure control. CONSTITUTION: The time (time t2 - time t1 ) from receiving a shake correction instruction (time t1 ) till starting shake correction control (time t2 ) is calculated based on the time Tstart (time t3 - time t1 ) till starting shake correction transferred from a body device and the calculated result Tjs (time t3 - time t2 ), and the starting timing of the shake correction mechanism is decided in the timing (time t2 ) much earlier than exposure control start timing (time t3 ) so as to start the shake correction control. At the time t3 , target shake control speed matches with control speed. Therefore, the driving speed of the shake correction mechanism is matched with or approximated enough to the target driving speed at the time of starting film exposure, so that the shake correction control of the shake correction mechanism is performed with high accuracy.

Filed: 1994-06-14
Abstract: PURPOSE:To improve the removal of an sludge component in sewage by sequencing previously plural aeration operation patterns in decreasing order of an aeration effect and changing the pattern based on the order of the aeration effect corresponding to a variation in the quality of water to be treated. CONSTITUTION:The pattern in which an aeration treating time and an aeration stopping time per one time is made constant during an intermittent aeration treating stage is sequenced in large order of repeating times of the aeration and the aeration stopping. Then, the difference between a nitrate nitrogen concn. and an ammoniacal nitrogen concn. in the water to be treated is calculated by an arithmetic processor 9, and, this difference and a previously set target value are compared by a comparison arithmetic processor 10. By the comparison arithmetic processor 10, when the difference between the nitrate nitrogen concn. and the ammoniacal nitrogen concn. in the water to be treated is smaller than the target value, it is judged that the presently operating pattern must be transferred to a pattern higher in the aeration effect. On the other hand, when the calculated value is larger than the target value, it is judged that the presently operating pattern must be transferred to a pattern lower in the aeration effect.
