Title: Beam splitter
Inventor: ONO SHIYUUSUKE
IPC: G02B5/00
Filed: 1982-07-16
Abstract: PURPOSE:To reduce an area of a reflection film and to make a beam splitter small-sized and lightweight, by providing a total reflection film on a small area part in parallel plate glass, totally reflecting a part of light which transmits a photographic lens, and leading it to an optical finder. CONSTITUTION:The greater part of light which transmits a photographic lens does not hit a total reflection film 21 but passes through without stopping, and forms an image by the remaining photographic lens. On the other hand, light which hits the total reflection film is all reflected and becomes incident light of an optical finder system. The quantity of light of the same extent as the quantity of incident light to the optical finder by a semitransparent reflection film of a conventional example having a reflection factor of about 20% can be obtained by the total reflection film 21 having an area of about 1/5. Also, a shape of the total reflection film 21 is made long in a vertical direction 24 to both an optical axis 22 of the photographic lens and an optical axis 23 of the optical finder. In this way, it is possible to obtain a beam splitter which has the quantity of light of the same extent as the quantity of incident light to the optical finder by a conventional example, also is thin in thickness in the direction of the optical axis 22 of the photographic lens, and accordingly, is small-sized lightweight.

Title: Phase arithmetic circuit
Inventor: NISHIGORI YOSHIHISA
IPC: H04N9/45
Filed: 1988-05-23
Abstract: PURPOSE:To execute phase operation, in which the generation of an error is a little, with one step of an adding circuit and to cause a circuit scale to be small by changing an adding value with using a counter which counts the clock of a specified frequency. CONSTITUTION:When the clock of 13.5MHz is inputted to an adding value generating circuit 1, an angle thetaN of a sub carrier during one sample period, which is in case a sub carrier frequency is sampled by 13.5MHz, is outputted. A binary value corresponding to the angle thetaN is outputted from the circuit 1 and inputted to an adding circuit 2. Cumulative addition is repeatedly executed to the inputted adding value in the circuit 2 and the phase of the sub carrier is outputted in respective sample points. Thus, since the adding value is changed with using the counter which counts the 13.5MHz clock, the phase operation of the small error generation can be executed by one step of the adding circuit and the circuit scale can be made small.
