Title: Waste heat recovery heat exchanger
Inventor: SUZUKI TSUNEO
IPC: F28F9/02
Filed: 1984-05-14
Abstract: PURPOSE:To obtain a waste heat recovery heat exchanger with high reliability and favorable maintenability by a structure wherein headers are arranged away from the extension lines of heat transfer pipes and at the same time short pipes with bend are used for connecting the headers and the heat transfer pipes. CONSTITUTION:Headers 20 are arranged away from the extension lines of heat transfer pipes 16 and bent pipes are employed for short pipes to connect the headers 20 and the heat transfer pipes 16. Due to the structure as mentioned above, the thermal expansion in the heat transfer pipes 16 developed by contacting with the high temperature exhaust gas 21 exhausted from a gas turbine can be absorbed not only at the U-pipe 17 sides but also at the header 20 sides by the elasticity developed from the form of the short pipes 18. In addition, the energy of thermal expansion of the heat transfer pipes 16 are divided among various portions, resulting in developing proper thermal stresses at welded portions 22 and 23 and consequently eliminating damages from occurring at the welded portions. Further, the employment of the beint pipe for the short pipe 18 to connect the header 20 and the heat transfer pipe 16 causes to improve the accessibility to the welded portions 22 and 23 and the like and the maintenability, because the space for inspection is made larger.

Title: Ink jet head
Inventor: SEKIYA TAKURO
IPC: B41J2/045
Filed: 1985-05-02
Abstract: PURPOSE:To obtain an ink jet heat capable of being easily produced in a multiple form or an integrated form, by a method wherein two metals differing in coefficient of thermal expansion are provided in a laminate construction in an ink-pressurizing liquid chamber. CONSTITUTION:A substrate 1 is etched to provide a groove, and a metal 2 having a coefficient of thermal expansion different from that of the metal 1 is vapor-deposited on the groove part. An insulator 3 and conductors 5 for passing an electric current to heating elements 4 are provided to produce an upper substrate 1 of the head. A lower substrate 6 of the head is provided by providing ink-ejecting ports 7, grooves and ink reservoirs. The upper substrate and the lower substrate are laminated with each other, and an ink is supplied through an ink inflow passage 8. With the heating element 4 energized, the laminate construction part is deformed starting from the metals 1, 2 having different coefficients of thermal expansion, resulting in a change in the volume of the ink-pressurizing liquid chamber, whereby an ink is ejected. Alternatively, light from a laser light source is directed to the head 10 to heat a part H of the head 10, whereby the laminate construction part is deformed, thereby ejecting the ink through a nozzle 7.

Title: Scanning type electron microscope
Inventor: SATO TATSUO
IPC: H01J37/141
Filed: 1989-04-14
Abstract: PURPOSE:To amplify second electrons effectively without losing first electrons due to dispersion and also miniaturize the constitution of the invention stated in the title by making the bore diameter of the lower electrode of an objective lens larger and that of the upper electrode smaller, and providing a second electron detector in a space between the electrodes. CONSTITUTION:A first electron beam is condensed by a condensor lens, an objective lens 11 and the like, and the target 16 of a sample room 17 which is connected to a pressure limiting aperture 12 is irradiated therewith, and a second electron beam 13 is emitted from the target 16. The bore diameter of the lower magnetic pole 9 of the lens 11 is larger than that of the upper pole 8, and the electron beam 13 makes a reciprocating movement in the direction generally perpendicular to a face that links electrodes 14a, 14b and the beam collides with gas and its energy becomes small, and then it is captured by the electrodes 14a, 14b of a second electron detector. Even when the distance between the aperture 12 and the target 16 is shortened, the running distance of the electron 13 therefore becomes longer, and so a sufficient amplification effect is obtained by ionization of gas molecules and also the constitution of the invention is made smaller by providing the second electron detector between the electrodes 8, 9.

Abstract: PROBLEM TO BE SOLVED: To enhance throughput by forming a structure protruding from a reference surface of an X-ray mask stage, so that an X-ray outputting window is intruded into a recess of a rear surface of an X-ray mask, thereby efficiently irradiating a radioactive ray on a wafer. SOLUTION: An X-ray outputting window 3 for outputting a radiant ray 13 exists at a center of an X-ray mask stage for mounting an X-ray mask 5. The window 3 has a structure in which the window 3 protrudes from an X-ray mask stage reference surface 2 to intrude into a recess of a rear surface of the mask 5. A distance from the rear surface of the mask 5 to a mask frame 6 is accurately set. Since thicknesses of the frame 6 and an iron piece 9 are accurately decided, a position of a magnet 7 mounting surface from the surface of an X-ray mask stage 1 is accurately decided. The position of the mask 5 is accurately decided by thus positioning. Accordingly, a gap between the mask 5 and the window 3 can be reduced to 1/10 or less of that of prior art, and hence a reduction can be suppressed to 3% or less.

Title: Detector for state of plate
Inventor: YUURUGEN REEDAA
IPC: B41F33/00
Filed: 1983-05-31
Abstract: A machine for scanning printing plates to determine the ratio of "printing" to "non-printing" area for pre-adjustment of the ink dosing elements of a printing machine has an array of electronic photo-sensors, each sensor being disposed in a channel having low-reflection chambers which permit sharp delimination of resolution elements on the printing plate and ensure high definition scanning of different types of printing plates under practical conditions. Preferably the diaphragms dividing the channel into chambers have greater spacing at greater distances from the element sensed on the printing plate. To accommodate printing plates of different materials, means are provided for selecting the wave length of the light source. To prevent measurement error due to changes in the distance from the printing plate to the light source and sensor array, the photosensor array is preferably directed or aimed 60 DEG to 45 DEG  with respect to the normal vector of the printing plate, and the light source is in the same quadrant as the photo-sensor array at an angle of 0 DEG  to 45 DEG  with respect to the normal vector. Automatic calibration, automatic printing plate size determination, automatic sensing of identification information engraved on the printing plate, and a stairstep scan to increase the scanning rate are provided by suitable procedures executed by a microcomputer controlling the scanning process and analyzing, adjusting, and interpreting data received from the sensor array.

Abstract: PURPOSE:To prevent the load increase at the time of paper conveying due to a half-moon roller by separating the half-moon roller from a bundle of paper by a push-down means. CONSTITUTION:A half-moon roller having been in the stationary state is brought into contact with the uppermost paper of a bundle of paper P at paper feeding so as to feed paper to the side of a feed roller 6. And the half-moon roller 5 is rotated about 270 deg. and feeds the uppermost paper and then, it is stopped, while a rotary body 10 pushes this paper further downward at this point of time. That is, at this point, the bundle of paper P is separated from the half- moon roller 5. The paper is conveyed by the feed roller 6 in the downstream or a conveying roller in the further downstream at this point, but as the rotary body 10 pressed into contact with the rear end of the paper is rotated with it, load at paper conveying is reduced. And after the rear end of the paper passes the rotary body 10, the half-moon roller 5 is rotated again to the original state.
