Abstract: PURPOSE:To easily change a conventional close contact image sensor into a flat bed image sensor by combining the image sensor with an original support plate whose thickness differs from that of the sensor so as to control a focal position of a short focus image forming element from above the original support plate. CONSTITUTION:A point light source array 4 is used to light up an original 1, the image of light information from the original 1 is formed to a light receiving section of a sensor array 2 by using a short focal image forming element array 5 and the sensor array 2 converts the light information into an electric signal. The thickness of an original support plate 6 is thinner than the thickness of the close contact image sensor and then the focal point is located above the original support plate 6. Thus, the thickness of the original support plate 6 is varied to select freely the distance between the original support plate 6 and the focal point, and then the close contact image sensor is changed into a flat bed image sensor simply by using components of the conventional close contact image sensor without need of processing a frame body 7.

Title: Photoelectric conversion device
Inventor: KINOSHITA HIROAKI
IPC: G02B6/42
Filed: 1985-12-18
Abstract: PURPOSE:To reduce optical coupling loss by forming a lens made of a resin using a boundary surface in common together with a reflecting surface on the reflecting surface expanded toward the directions of the transmission and reception of beams in the periphery of a photoelectric conversion element, burying the photoelectric conversion element into the lens and specifying the aperture diameter of said reflecting surface and the height of the lens made of the resin. CONSTITUTION:A recessed section with a circular opening section is formed to the upper surface of a stem electrode 10. A reflecting surface 11 inclined so as to be upward expanded is shaped to the side surface of the recessed section. A light-emitting diode element 12 is die-bonded with the base of the recessed section. A surface electrode for the light-emitting diode element 12 and lead terminals are wire-bonded by extra-fine gold wires. Consequently, the light-emitting diode element 12 incorporated to a stem electrode 10 is buried into the lens 13 shaped by a transmitting epoxy resin having a refractive index of 1.2-1.7. In order to project beams emitted from the light-emitting diode element 12 efficiently to an optical fiber 20, an aperture diameter W is brought to 3mm or less and the aperture diameter W of the reflecting surface is set to the relationship of 1/3H<=W<=2H to the height H of the lens 13 from the surface of the element in relationship with the diameter of the optical fiber 20. Accordingly, the amount of beams radiated to the outside is reduced, thus minimizing loss by coupling.

Abstract: PROBLEM TO BE SOLVED: To improve the heat efficiency of a ceramic heater by providing a supporting body supporting the ceramic heater and a heat insulating layer formed between the ceramic heater and the supporting body and setting the heat conductivity of the heat insulating layer lower than that of the supporting body. SOLUTION: The heat insulating layer 11 is provided between the ceramic heater 10 and the mount surface 6d or 6a of a stay 6.
