Title: Mirror device for photographing
Inventor: ARIMOTO MIKIYUKI
IPC: G03B15/12
Filed: 1987-03-13
Abstract: PURPOSE:To prevent a decrease in the contrast of the image projected on a half mirror by subjecting the rear face of a mirror member except the enclosing range of a camera mounting part to light shielding and forming a mirror device in such a manner that the image transmitted through the half mirror part can be photographed by a camera mounted on the camera mounting part. CONSTITUTION:Since the axial center of the camera mounting part 3 is orthogonal with the plane of the mirror member 1, the optical axis of the camera (a) maintains the orthogonality with the plane of the member 1 when the camera (a) is fitted into the camera mounting part 3 provided to the rear face of the member 1. The shutter of the camera (a) is released where a subject person projects his own figure on the surface of the mirror part 1 member and determines his position. Then, the subject image is transmitted through a semitransparent part 6 and is formed on a camera film. The photograph of a framework projected on the member 1 is thus surely obtd. The part of the member 1 except the camera mounting part 3 is subjected to the light shielding to prevent the fall of external light to the rear face of the member 1. The decrease in the contrast of the subjected image projected on the mirror member is thereby obviated.

IPC: G06F7/52
Filed: 1988-03-14
Abstract: PURPOSE:To shorten computing time by shortening the holding time of a divisor and a dividend by deriving in advance a first substantial partial predictive value by a second quotient predictive circuit. CONSTITUTION:When a divider D and a divided N are inputted successively, they are set to a divisor register 11 and a partial residue register 10, and also, supplied to the second quotient predictive circuit 20 and a partial quotient predictive value is derived. The circuit 20 is constituted in the same way as a partial quotient predictive circuit 14. At the time of starting an operation, a selecting circuit 21 selects the output of the circuit 20 by a START signal, and outputs the partial quotient predictive value to a partial quotient predictive register 22. Thereafter, a partial residue is derived by subtracting the output of a multiple generating circuit 12 from the value of the register 10 by an adding circuit 13, and returned to the register 10. The circuit 14 generates a partial quotient predictive value which becomes a control signal to the circuit 12 from the high-order (a) bit of a result of the circuit 13 and the high-order (b) bit of the register 11. The circuit 21 selects the output of the circuit 14 after a second cycle, therefore, the arithmetic operation is repeated thereby.
