When light is detected on the pupil Ep of an eye to be examined at the detected luminous flux position 9a in the direction vertical to the stripe longitudinal direction of the lattice part 50 with respect to a projected luminous flux position 2a, the linear stripes of the lattice part 50 are curved corresponding to the unevenness of the eyeground Er. This curving is proportional to the depth of each part of the eyeground Er. The video signal at an observation point is once converted by an A/D converter to be stored in a memory and subjected to regression calculation by a signal processing part 12 to calculate depth distribution.

Title: Transmitter with delay compensation type adaptive predistorter
Inventor: FURUYA YUKITSUNA
IPC: H03F1/32
Filed: 1987-02-24
Abstract: PURPOSE:To compensate delay adaptively by adding a circuit which delays an input signal automatically by optimum time. CONSTITUTION:An adder 102 adds a correction quantity from a RAM 101 to the signal inputted from an input terminal 100 and the resulting signal is inputted to a transmitting amplifier 104 through a modulator 103. The output of an amplifier 104 is outputted from a terminal 120, a subtracter 105 subtracts the output of a demodulator 105 from the input signal delayed by a variable length delay circuit 112 through the demodulator 105, and the subtraction value is applied to an optimizing circuit 107. The circuit 107 increases or decreases the contents of the RAM 101 according to whether or not the output of the demodulator 105 is large. The circuit 107 adds the output of the subtracter 106 to the output of the RAM 101 and writes the result in the RAM 101. A differentiating circuit 108 differentiates the output of a circuit 112 and multiplies 109 its sign by the output of the subtracter 106. An LPF 110, therefore, removes the influence of the strain of the amplifier 104 and a delay control circuit 111 controls the delay quantity of the circuit 112 according to the output of the LPF 110 to minimize the distortion due to a delay error.

Abstract: PROBLEM TO BE SOLVED: To lighten the sudden change of an emitting angle and to improve image quality by forming the Fresnel angle of at least each lens part near the center of a Fresnel lens as an inverted angle at every specified pitch. SOLUTION: As for the Fresnel lens 10; bent-like lens parts 11 are arrayed at the specified pitch, the Fresnel angle θ of each lens part 11 is formed to become larger and larger at a fixed rate from the center part to the periphery part, and the Fresnel angle θ of each lens part 11 near the center is formed as the inverted angel (positive and negative are inverted) at every pitch, and the respective lenses 11 are formed to be linearly symmetric with respect to the center part. In such a case, when light from a projection lens is made incident on the lens 10, the emitting direction of a light beam is inverted at every pitch. Therefore, the emitting angle of the light beam is not changed suddenly in the center part of the lens 10 so as to lighten the sudden change of the emitting angel in the center part.

Abstract: PURPOSE: To obtain an electrical contact material with superior fusion bonding resistance and superior transfer consumption characteristics by dispersing Zn oxide and Bi-Sn oxide in Ag matrix in a specified ratio.  
     CONSTITUTION: A metal mixt. consisting of Bi 1.5W5%, Zn 2W10%, Sn 0.5W4% and the balance Ag or further contg. Ni or Co 0.05W0.5% is melted in an Ar atmosphere and cast in a metal mold.

This powder is heated in air at 650°C for 60hr. to selectively oxidize the Bi, Zn and Sn, thereby dispersing oxide particles of ZnO and Bi 2 Sn 2 O 7  in the Ag. This material is then passed through a rolling mill to form chips of 0.2mm or less in thickness, and the chips are washed, filled in a tube, press-molded, and sintered at 800°C. This sintered body is further sintered under press., worked into a wire rod of 3mm in diameter by warm extrusion, and annealed at 650°C to obtain an electrical contact pin.
