Title: Electron source for display tube
Inventor: TAKAGI SEISHI
IPC: H01J31/15
Filed: 1989-10-05
Abstract: PURPOSE:To enhance the display characteristics by forming a thin wire type cathode of a thin wire as heater with insulative covering, a metal pipe wrapping the thin wire, and an element emitting substance affixed to the outer surface of the metal pipe. CONSTITUTION:A thin wire type cathode 30 consists of a tungsten thin wire 34 as heater of several tens of mu-meters in dia. covered with an insulating substance 32, a metal pipe 36 made of substance such as Ni, Cr of several tens thru hundreds of mu-meters in dia. wrapping the thin wire 34, and an electron emitting substance 38 as (Ba, Sr, Ca) O applied to the outer surface of this metal pipe 36.

Title: Heat exchanger
Inventor: KONYA KOJI
IPC: F28F9/02
Filed: 1984-12-12
Abstract: PURPOSE:To firmly fix a separator plate and a gasket without a risk of their falling off of the separator groove area even if the thickness of a pipe plate of a heat exchanger is reduced to the minimum by installing a guide support in a gasket branch groove disposed in the water chamber side pipe plate of the heat exchanger. CONSTITUTION:A groove is formed to a depth of l3 in an area where a gasket 6 is inserted to a pipe plate 3. The depth of the groove is made barely enough to fit a support guide 7 to the groove, and may as well be 2mm which is smaller than the thickness of the gasket 6. A guide support 7 is attached to the pipe plate surface with a fastening screw 8 on both sides of a separator wall 2 to prevent the deformation of the gasket 6 and separator plate 2. The guide support 7 is given a sufficient thickness l4 in consideration of the deformation etc. of the pipe plate surface. By such an arrangement, the thickness of the pipe plate 3 is T1+l3 which is minimum yet sufficient. Since there is a guide support 7 on either side of the separator plate 2, its deformation can be prevented even if a load P is applied to the separator plate 2 due to the differential pressure. The wall thickness of the pipe plate can be reduced to the minimum, and the gasket 6 and separator plate 2 can firmly be fixed to the groove without falling off.
