Title: Condenser, heat collector, photo-detector having diffracting surface and photo-electric converter of artificial beams
Inventor: UEMATSU TSUYOSHI
IPC: H01L31/0232
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To make feasible of simplifying the macroscopic structure of a condenser, by a method wherein the refractive index of a medium of a heat collector having a part thereof in contact with the medium is specified to exceed that of the outer part of photodetecting surface. SOLUTION: A cylindrical heat collector fitted to a photodetector of a condenser heats the water running in the cylinder by the energy of the condensed beams. Since a heat collector is used for the photodetectors 6, in order to prevent the heat from being externally radiated, a cover glass 11 and an adiabatic layer 10 using an air layer are provided on the surface while another insulating layer 23 made of urethane are provided on the backside. A diffracting surface 7 is formed by bonding a sheet in the structure holding an aluminum reflecting member between plastic made surface and backside protective material onto the backside of a plastic medium 5. In such a constitution, the condenser having multiple juxtaposed photodetectors in a simple structure can form a heat collecting module in high heat collecting efficiency.

Title: Information retrieval device for microfilm printer
Inventor: YANAGAWA HITOSHI
IPC: G03B21/11
Filed: 1985-04-01
Abstract: PURPOSE:To prevent an unnecessary copy from being taken by inhibiting printing operation even when a print switch is pressed if a microfilm shifts in position and part of its image is displaced from a print frame. CONSTITUTION:If the film F shifts upward and its mark and detecting elements 5a and 5b have a position relation as shown in a figure, i.e. so that one detecting element 5a does not faces the mark 2, an amplifier 14 does out output a signal '1' any more, so the output '1' of an AND gate 16 is not outputted either. Therefore, a mark signal 20 is not stored in an RAM 9, so no print is made even when a print signal 21 is held at '1' by pressing the print switch 18. Consequently, a deficient print where a hatched image 1a is absent is not made, so wastes of a print, time, and paper are eliminated.

Filed: 1979-06-04
Abstract: PURPOSE: To prevent the generation of bubbles at the glass reinforcing part, by heating up the core block before giving the heat fusing to the glass in the glass filling process of the core block.  
     CONSTITUTION: Core block 3 is installed in the furnace, and the N 2  or Ar atmosphere is secured within the furnace. After this, the temperature of 750±10°C which does not fuse the glass is given in the furnace for 2.5W3.5min, and thus the gas absorbed into block 3 is eliminated. Then the temperature is increased in the furnace, and thus the filled glass is fused to secure the unification for both core blocks 3. At the same time, the glass is filled to notch part 5. As a result, the bubble generation factor is reduced greatly for the glass reinforcing part 2 of the magnetic head, thus increasing the quality of the magnetic head.
