IPC: H04B10/11
Filed: 1981-12-22
Abstract: PURPOSE:To realize office automation which is controlled by a small output and very economical, and has high safety with regard to an optical space propagation system which transmits beams of light through the space,by scattering beam light from a master station satellite at a subrodinate satellite and then sending it to a terminal device. CONSTITUTION:A master station satellite 6 is installed at a prescribed position of a ceiling 1 and plural subordinate station satellites 8 are fitted to the ceiling corresponding to centralized terminal devices 5; and a beam 7 transmitted from the master station satellite 6 is photodetected by the subordinate station satellites 8, which scatter the photodetected beams 7 to send scattered beams 4, thus controlling the terminal devices 5 corresponding to the subordinate station satellites 8. Therefore, the control is performed by the small output of the beams 4 because the distance of the subordinate station satellite 8 and terminal device is relatively short, so the output of the master station satellite 6 may be small.

Title: Solid-state image pickup device
Inventor: YABE HISAO
IPC: H04N5/335
Filed: 1986-09-05
Abstract: PURPOSE:To make an incident face in parallel with an image pickup face by providing a 1st and 2nd cover glasses on a solid-state image pickup element chip overlappingly and packing and forming a seal member to a bonding part coverred by the 2nd cover glass. CONSTITUTION:The 2nd cover glass 29 is bonded onto the 1st cover glass 28 to cover the bonding part by a bonding wire 27. The solid-state image pickup device 20 packs the bonding part between the base 22 and glass 29 by a seal resin 32. Since the parallelism between the incident face and the image pickup face is decided only by the parallelism of the glasses 28, 29, a local fog due to the tilt of the image pickup face is not caused. Since the seal resin 32 has only to seal the bonding part, the shape of the side face is not identical to the base 22 and glass 29 and the forming performance is much facilitated. Moreover, since no package is employed, the outer shape of the solid-stage image pickup device 20 is miniaturized.
