Title: Cooling type photoelectric conversion apparatus and manufacture thereof
Inventor: ARAKAWA ISAO
IPC: G01J1/02
Filed: 1990-08-08
Abstract: PURPOSE:To make it possible to improve cooling efficiency and MTF characteristic by providing a constitution wherein a heat exchanger plate and a supporting stage are bonded by fusion with metal. CONSTITUTION:A low-melting-point metal film (indium film) 32 is formed on the lower surface of a supporting stage 8A beforehand. A heater 37 for heating the low- melting-point metal film 32 from the lower surface side of the supporting stage (cooling bottom) 8A is provided. Under the state wherein a photoelectric conversion assembly and a cooling assembly are combined and a heat exchanger plate 36 and the low- melting-point metal film 32 are in contact, the heater 37 is heated, and the low-melting- point metal film 32 is fused. Thus the heat exchanger plate 36 is bonded to the lower surface of the supporting stage 8A by fusion. In the constitution wherein the heat exchanger plate 36 and the supporting stage 8A are bonded by fusion with the metal, the thermal resistance between the heat exchanger plate 36 and the supporting stage 8A becomes substantially zero. Pushing of the heat exchanger plate 36 to the supporting stage 8A is substantially omitted. When the heating is performed from the lower surface side of the supporting stage 8A, the heating becomes hard to give effect on a photoelectric conversion element.

Title: Original platen display of image reader
Inventor: ICHIKAWA HAJIME
IPC: G03B27/62
Filed: 1981-12-28
Abstract: PURPOSE:To mount an original accurately and speedily, by directly providing a platen with boundary lines of copying areas, their center marks, etc. CONSTITUTION:The number of sheets to be copied is set and displayed on a display. After the display is confirmed, copying operation is started. In this case, once the closure of an original cover (not shown in figure) is detected and a contact (q) is closed, a relay L is energized to switch its contact l from a side ON to a side OFF, and both electrodes of displayed EC element marks are short-circuited to turn off them. After the EC elements for a copying area are turned off, the copying operation is started, so the marks are not copied. An EC element mark EC0 is irrelevant to form size and contraction ratios and indicates a comment regarding, for example, copying; the element is turned on when a manual switch SW1 is turned on and once the closure of the original cover is detected, the contact l is broken to short-circuit both electrodes of the EC element, which is turned off, so that its mark is not copied.
