Title: Electrode structure of in-line type
Inventor: NAIKI KAZUAKI
IPC: H01J29/50
Filed: 1982-08-02
Abstract: PURPOSE:To both form a main electron lens opening in a large bore size and obtain an electron beam of small astigmatism even for extreme approximation of openings to each other, by forming a curved surface whose configuration is recessed toward the inside of an electrode in such a direction as crossing at a right angle with the arrangement direction of three openings in an electrode constituting a main electron lens of a color picture tube electron gun. CONSTITUTION:A closed face 22 is so formed as to include a curved surface of recessed shape protruding with a curvature toward the inside of an electrode in the direction crossing at a right angle with the arrangement direction of openings, and the narrowest part 25 of a space between neighboring openings 21R, 21G and 21G, 21B is located in an internal side of the electrode by (d) from the peripheral edge of the closed face 22. The central part, in which the three openings 21R, 21G, 21B of the closed face 22 are drilled, is located in an internal side of the electrode by a distance (d) apart from the peripheral edge of the closed face 22. Accordingly, equipotential line groups 26, 26' being the electrostatic field forming a main electron lens form almost equal electrostatic electron lenses individually for each electron beam permeable opening, within a section (horizontal plane in respect to fluorescent screen) containing three electron gun axes 20R, 20G, 20B, thus astigmation being reduced to very small degree. Then, an aberrationless beam spot in which longitudinal and lateral sizes of an electron beam section are coincident with each other, is obtained on a fluorescent screen.

Title: Time base extension device
Inventor: KOHIYAMA KIYOYUKI
IPC: G06F5/00
Filed: 1990-05-25
Abstract: PURPOSE:To economically use a memory resource by executing a write operation by means of a first clock and a read operation by means of a second clock while plural memories are sequentially switched. CONSTITUTION:Data are sequentially written in m-number of storage areas M1-Mm in accordance with the first clock CK1, and data are sequentially read in accordance with the second clock CK2 with a frequency lower than that of the first clock CK1. Consequently, the time base of data can be extended compared to the ratio of two clocks. Here, a series of data string is divided into n-number of unit data and the writing/reading into storage areas M1-Mn are executed for respective divided data. Other divided data are read from the other storage areas in parallel while arbitrary divided data is written in the arbitrary storage area. Thus, a total storage capacity does not exceed a series of data capacity even if it is maximum and a memory capacity can be reduced.

Title: Low-pressure casting method
Inventor: NAGAI SHUSUKE
IPC: B22D18/04
Filed: 1985-06-21
Abstract: PURPOSE:To prevent galling and to improve yield by feeding a waste gas from a holding furnace into a part where a product and a metallic mold are liable to gall to create a gap in the stage when the gas is discharged from the inside of the holding furnace upon solidification of a molten metal in a cavity. CONSTITUTION:Compressed air is fed from a pressurizing gas supply source 21 via a suction and discharge hole 7 into the holding furnace 1 to pressurize the molten metal 3 and to charge the molten metal via a stalk 5 into the product cavity 13 in the metallic mold 9. The gas is discharged from the hole 7 upon solidification of the molten metal 3 in the product cavity 13. The waste gas is introduced via the 1st nozzle 17, pressurizing gas pipings 18, 22, a solenoid valve 23 for discharge and the 2nd nozzle 24 into a main passage 15. Since the passage 15 is constituted as partly throttled orifice, part of the waste gas introduced therein is ejected via plural auxiliary passages 16 (about 0.2mm thickness) onto the contact surfaces where the mold 9 and the product are liable to gall, thereby forming the air gap. The generation of galling is thereby obviated even if the casting is parted from the mold by opening the mold.

Title: Steam overheating reducer, steam generator and boiler
Inventor: KUSAKA IWAO
IPC: F22G5/12
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a steam overheating reducer which enables safe application in a fully loaded zone by cooling the whole of a nozzle system to enable the prevention of the occurrence of heat stress even when a spraying flow rate is reduced under a high operation load. SOLUTION: A nozzle stem pipe 1 is arranged in a steam piping and is constituted of an inner tube 3 with the tip part thereof closed and an outer tube 4, provided with a spraying hole 2, which is arranged outside the inner tube 3 with an interval part. The inner tube 3 is provided with outflow holes 5-8 by which the flow velocity of spray water flowing into the inner tube 3 is increased to let the water flow out to the side of the outer tube 4 while being made to pass through a clearance part between the inner tube 3 and the outer tube 4 without retention, which enables the formation of a flow which runs to every corner of the nozzle stem pipe 1 to reach the spraying hole 2. Thus, the whole of the nozzle stem pipe 1 can be cooled thoroughly, thereby eliminating heat stress on the flow of steam even when sprayed liquid drops adhere to the rear side of the nozzle stem pipe 1.

Title: Index device capable of direct-acting drive and rotation
Inventor: KOIKE YUKIO
IPC: B23Q16/06
Filed: 1981-08-31
Abstract: PURPOSE:To aim at miniaturizing a device in size and reducing manufacturing costs, by making its functions such as direct-acting drive, rotation, indexing, etc., operatable only switching fluid passage with a suchlike device shaped something like a bar as a whole. CONSTITUTION:When the amount of projection from a turn table 49, or rather a work holder, is increased, fluid is fed to a port e. This fluid flows into a chamber 7 and forcibly presses a direct-acting piston 46 to the right in illustration while the piston 46 travels on a serration shaft 23 inside a cylinder 44 in the projecting direction of the table 49. On the other hand, when the table 49 is rotated by a certain angle, fluid is fed to a port d. In this case, fluid flows into chambers 42 and 43 and moves a hydraulic clutch 31 to the right in illustration whereby engagement between an index pin 37 and a notch 38 is released. Next, fluid is fed to a port a of an oscillating rotary actuator 21, and a rotor 26 is turned round counterclockwise. With this, a power shaft 28 is as well rotated and thereby the table 49 gets rotated via the clutch 31, an intermediate shaft 32 and the serration shaft 23 in addition.
