Filed: 1988-03-23
Abstract: PURPOSE:To improve the image drawing accuracy by providing a hole to pass charged beams on the detection surface and arranging holes or cuttings to pass the other beams at both sides of the hole. CONSTITUTION:The electron detector 19 is a ring form, and not only a passage 27 of electron beams 1, but also passages 24 and 25 to pass the light are arranged.

Title: Heat exchange pipe for condenser
Inventor: HONDA HIROSHI
IPC: F28F1/26
Filed: 1982-04-21
Abstract: PURPOSE:To increase the effective surface area of heat conduction of the heat exchange pipe by a method wherein the heat exchange pipe attached with fins on the outer periphery thereof in the axial direction with the formation of grooves among the fins is arranged almost horizontally within a condensable gas atmosphere, while a cooling fluid is flowed through the pipe so that a liquid staying in the grooves among the fins drops immediately and a film of the liquid formed on the surface of the heat exchange pipe becomes small in thickness to thereby reduced the surface area of heat conduction covered by a thick layer of the liquid film. CONSTITUTION:The grooves 3a and the fins 3 are formed alternately on the outer periphery of a pipe 2 made of a good heat conductive material such as copper so that the fins 3 make themselves an integral heat conductive means as a whole to thereby form the finned heat exchange pipe 1. Thus, when a plurality of such heat exchange pipes are used as multistage and multilined heat exchange pipes of a shell end tube type condenser, the condensable gas around each of the pipes condenses to adhere to the surfaces of the pipe 2 and the fins 3 and fills the grooves 3a among the fins 3 in the form of a liquid heat medium layer. Then the liquid heat medium flows down along the pipe through the grooves under its own weight. In this case, a porous plate 4 provided at the bottom of the pipe 1 performs the function of inducing the condensed liquid in the grooves 3a due to its capillary action and as a result, the condensed liquid is forced to flow down actively at a rate higher than the flow rate due to its own weight so that the dropping of the condensed liquid is promoted.

Abstract: PURPOSE:To reduce errors without requiring detection in a wide wavelength range for a photo detector, by providing a reflecting film adapted to transmit signal lights while reflecting reference light between material and a fiber for transmitting and receiving light with the wavelength of the reference light smaller than that of the signal light. CONSTITUTION:Emission lights from LEDs 2 and 3 driven by a drive section 1 are combined 4 and introduced into material 8 by way of a fiber 7 for transmitting and receiving light passing through a distributor 5. A reflecting film 12 varying in the reflectance depending on the wavelength is provided on the LED side of the material 8. The characteristic of the film 12 is such that the absorption end thereof is positioned right on the low wavelength side of the signal light. The reference light is reflected mostly on the surface of the material 8 and all passing through the film 12 is absorbed as passing through the material 8. Light from an LED 3 for signal lights mostly passes through the reflecting film 12 and is reflected on a reflection mirror 9 to make it proper in the temperature transmission level so that it allows the light to pass through the fiber 7 together with the reference light to be converted into voltage with a photodiode 6 and a light receiving section 10. The resulting signal is compared with the transmission level with respect to the temperature previously memorized with a signal processing section 11, thereby enabling the detection of temperature.
