Filed: 1996-10-15
Abstract: PROBLEM TO BE SOLVED: To conduct transmission/reception of image between personal computers by giving an image 4 read by a scanner to a personal computer in a prescribed image data form, controlling a modem to send image information to an opposite personal computer through the modem. SOLUTION: Upon the entry of a terminal number of a destination personal computer B, a CPU 4 acquires the entered terminal number via a serial interface section 16, stores the number to a prescribed area of a DRAM 6 to monitor depression of a start key in an operation section 13. When the depression of the start key is detected, the CPU 4 gives a command to a scanner interface section 16 to allow the scanner to read an image from an original. In this reading, a color CCD line sensor sequentially reads image data in three primary colors via respective color filters. Since a signal outputted from the color CCD line sensor is an analog signal, the signal is converted into a digital signal.

Abstract: PURPOSE:To prevent a head element from being destructed or to prevent a core block from being positionally shifted from a protection plate by arranging a spacer formed by a material to be softened at the softening temperature of a glass layer between a core block and a protection plate and heating the spacer while applying a force to the core block and the protection plate in the mutually approaching direction to bond both the members with glass. CONSTITUTION:The spacer 4 formed by the material to be softened at the softening temperature of the glass layer 3 is arranged between the core block 1 and the protection plate 2 and a gap 6 is formed between the head element 11 and the glass layer 3 to superpose the core block 1 to the protection plate 2. A part or the whole of the spacer 4 is softened by heating while applying force to the plate 2 and the block 1 in the mutually approaching direction of both the members 2, 1 to bond the plate 2 and the block 1 with glass. Since the head element 11 is prevented from being destructed due to load to the core block 1 and the core block 1 and the protection plate 2 can be set up with sufficient pressure, the core block 1 and the protection plate 2 is prevented from being positionally shifted by vacuumization or air flow in a glass fusing furnace.
