Title: Reflecting and refractive type objective optical system
Inventor: OINUMA TOSHIAKI
IPC: G02B17/08
Filed: 1983-06-02
Abstract: PURPOSE:To remove technical complexity of production by arranging a surface reflecting sub-mirror of which projected surface is opposed to a surface reflecting main mirror arranged so as to be opposed to a substance and adjacently arranging a concave meniscus lens and a convex meniscus lens at a position close to the main mirror so that their recessed surfaces are opposed to the sub-mirror. CONSTITUTION:Light flux from the substance is reflected at first by the surface of the main mirror L1 which is a concave reflector as shown by arrows and converged in the direction of a main mirror focus. The submirror L2 of which projected surface is opposed to the main mirror L1 is arranged in the front of the main mirror focus and light flux incident to the sub-mirror L2 is reflected on the surface of the submirror L2, and while being converged modarately by the divergence effect of the sub-mirror, made incident to a compensating lens system consisting of the concave and convex meniscus lenses L3, L4 arranged close to the main mirror L1. A hole for projecting the light flux is drilled on the center of the main mirror L1 and the light flux transmitted through the compensating lens system forms its image with a practically proper back focal distance on the back of the main mirror and the compensating lens system.

Abstract: PURPOSE:To realize conversion to a long distance between a channel device and an input/output device easily and economically, by providing an adaptor between the channel device and the input/output device so that a data, etc. can be transferred at a high speed by an optical signal between the adaptors. CONSTITUTION:Transmission frame controlling circuits SFCa, SFCb are operated, an adaptor ADP1 sends out a synchronizing signal and a state of a channel interface CH.I/F, and an adaptor ADP2 sends out a synchronizing signal and a state of an I/O CH.I/F. Receiving frame controlling circuits RFCa, RFCb detect the synchronizing signal from photoelectric converters OEa, OEb, shift the signal as a receiving data into registers R1a, R1b, set it to R2a, R2b, and also to R3a, R3b, and transfer it to CH.I/F circuits IFa, IFb. The adaptors ADP1, ADP2 relay a signal between the CH device and the I/O device. In this way, in the start sequence, in case of a command which requires a data transfer, it is shifted to the data transfer sequence after the start sequence has ended, and it becomes the end sequence after said sequence has ended.
