Title: Optical pulse tester using heterodyne light receiving
Inventor: ICHIKAWA AKIO
IPC: G01M11/00
Filed: 1990-09-28
Abstract: PURPOSE:To prevent the fluctuation of phase difference by splitting returned light and locally oscillated light into orthogonal polarized-light components, performing optical heterodyne detection, offseting the phase difference between the orthogonal polarized-light components at the optical wave stage in the state of the electric signal after the detection, and performing addition. CONSTITUTION:Returned light 13 in the state of polarized light and locally oscillated light are split into the polarized-light components in the directions X and Y in a polarized-light beam splitter 2 through an optical directional coupler 1E. The polarized-light components of the returned light 13 in the directions X and Y and the polarized-light components of the locally oscillated light 12 in the directions X and Y are synthesized. The optical heterodyne detections are performed in photodetectors 3A and 3B. The signal of the frequency difference DELTAf between the returned light 13 and the locally oscillated light 12 is obtained. The outputs from the photodetectors 3A and 3B are inputted 5A and 5B into a phase corrector 5 through detectors 4A and 4B. In adder 6, the outputs from the detector 4A and the corrector 5 are added. Thus, the fluctuation of the phase difference between the orthogonal components of the polarized lights is prevented.

Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To read and set set information automatically at a desired photographing place by storing set information received by a communication means to make communication with an external device to a storage means and setting the photographing condition according to the set information stored in the storage means. SOLUTION: An infrared ray reception section 114 of a digital still camera 1 receives data required for photographing such as a shutter speed, a compression rate and a resolution sent from an external personal computer PC and sets the received set data to a set data storage area of a flush memory 104. In the case of photographing mode, each of set data is read from the set data storage area of the flush memory 104 and sets the data to a photographing section 107 and an image compression processing section 120. Thus, the photographing condition is easily set and since the photographing condition is automatically set by having only to select the photographing mode, an unintended photographing result is avoided.

Filed: 1993-10-19
Abstract: PURPOSE:To reduce load capacity of a bit line, to reduce power consumption and to perform reading and writing at high speed by providing a switch circuit to divide a memory cell array and performing ON/OFF control in accordance with an address. CONSTITUTION:Memory cell arrays 102, 108 are constituted with memory means which hold data of reading/writing, these memory means are selected by an output result of a row decoder 100 to which an address ADDR is inputted. A switch circuit 103 connects or separates bit lines of the inside of the memory cell arrays 102, 108 by ON/OFF operation, and divides the memory cell arrays 102, 108. A control circuit 107 generates a control signal CNT of the switch circuit 103 by making a part of an address ADDR as an input signal. Thereby, in writing and reading, since each bit line is cut off by a switch circuit, load capacity of bit lines is influenced by only the half of all memory cells. Therefore, reducing power consumption and increasing operation speed can be attained.
