Title: Flat bed type microcamera
Inventor: SHIOZAWA ETSUO
IPC: G03B27/32
Filed: 1992-07-22
Abstract: PURPOSE:To eliminate the need for deburring of an aperture mask and pressure plate and to improve productivity by forming the mask and pressure plate of hardened stainless steels. CONSTITUTION:The aperture mask 44 and pressure plate 62 are produced by hardening members formed by subjecting the stainless steels to machining, such as turning and polishing. The pressure plate 62 is preferably subjected to black plating in such a case. Burrs are not produced in this plating treatment. The mask is heretofore provided with pins for guiding a film, but the mask 44 in such a case has not such pins and its film traveling surface is smooth. The film 36 is guided by annular grooves formed on the outer peripheries of a guide roller and drive roller. The film 36 is, therefore, easily loaded between the mask 44 and the pressure plate 62. In addition, the plane working of the film traveling surface of the mask 44 is easy and the flatness accuracy of this surface is enhanced.

Abstract: PURPOSE:To reduce the cost by receiving a position measurement radio wave whose received electric power distribution is so shaped that received electric power is maximum at >=3 ground fixed points and measuring the position of a moving body from the received popwer ratio of the radio wave and position information on the fixed points. CONSTITUTION:The thin-beam position measurement radio wave is radiated from a satellite 1 positioned on a geo stationary track to the fixed points (a), (b), and (c) on the ground surface and this radio wave is used to measure the position of the moving body M. The moving body M receives three position measurement potentials by a receiver which is mounted on the moving body and not shown in a figure to find respective received power distributions Pa, Pb, and Pc. Those distributions shows the numbers of times of distances from the fixed points (a), (b), and (c), so when the positions of the fixed points (a), (b), and (c) are already known, they are measured and a position measuring means which is not shown in a figure calculates the position of the moving body M itself from the ratio of received power values. Thus, the position of the moving body is measured without being affected by clouds nor rain in the sky.
