Title: High-precision measuring method for center position of light
Inventor: NARUSE HIROSHI
IPC: G01C3/06
Filed: 1985-11-01
Abstract: PURPOSE:To measure the center position of reflected light from an object with high precision by finding and utilizing the reflection factor rate of a surface to be irradiated to correct a light intensity distribution and approximating the quantized light intensity distribution to a continuous light intensity distribution curve by a minimum square-law method. CONSTITUTION:The object 2 is irradiated with light having uniform light intensity from a reference light source and its reflected light is detected by a visual sensor 3 arranged opposite the object 2. Light intensity obtained at each point is divided by maximum light intensity to find the reflection factor ratio of the surface to be irradiated of the object 2. Then, the object 2 is irradiated with measurement light from a light source 4 for measurement and reflected light at this time is made incident on the sensor 3 to find the light intensity distribution of the reflected light. Then, the light intensity distribution of the reflected light is divided by the reflection factor ratio to correct the influence of nonuniformity of the reflection factor of the surface to be irradiated. Then the light intensity distribution curve which varies continuously is found from the corrected light intensity distribution by using the minimum square- law method to determine the center position of the reflected light.

IPC: G06T11/00
Filed: 1989-09-20
Abstract: PURPOSE:To perform a bit-built operation at a high speed by carrying out the bit-built operation via a shift register. CONSTITUTION:The image data on the transfer destination and origin addresses of a memory cell 2 are transferred to 1st and 2nd shift registers 3 and 4 respectively. An arithmetic circuit 5 performs a bit process based on the data received from both registers 3 and 4, and the processing result is stored in the register 3. The contents of the register 3 thus obtained are collectively sent to the cell 2. In such a process system, the access frequency is reduced to the cell 2 and therefore the time required for a bit-built operation is shortened.

IPC: A61B5/055
Filed: 1989-09-20
Abstract: PURPOSE:To adjust intensity of a high frequency pulse, in its turn, to set thetaat a high speed and accurately about each inspection body by using a pulse intensity adjusting sequence. CONSTITUTION:A pulse adjusting sequence is such that high frequency pulses C, D for forcedly resetting a nuclear spin to a condition before excitation are added after high frequency pulses A, B. Timing of adding the high frequency pulses C, D is set in a manner wherein the point of time t1 of applying the high frequency pulse A and the point of time t5 of applying the high frequency pulse D are symmetrical with the point of time t2 of applying the high frequency pulse B and the point of time t4 of applying the high frequency pulse C symmetrical with the point of time t3 of generating an echo signal serving as the reference. Intensity of the high frequency pulse C is equal to that of the high frequency pulse B. Intensity of the high frequency pulse D is equal to that of the high frequency pulse A, but a direction of throwing down a nuclear spin by the high frequency pulse D is opposite to a direction of throwing down the nuclear spin by the high frequency pulse A. Accordingly, the nuclear spin can be forcedly reset to a condition before excitation, and an action equal to shortening of a moderation time is obtained.

CONSTITUTION:A diffracted beam radiated from a diffraction grating 2 progresses in a direction perpendicular to an axis of a laser resonator, is reflected by a reflector 7 formed on the surface of an epitaxial growth layer, is coupled again to the diffraction grating 2 and is coupled to a laser mode. Only when it is coupled to the laser mode in an identical phase, a narrow line width of an oscillation spectrum is obtained. Electrodes 9 are formed on the right and on the left in a phase modulation region 6; a refractive index is changed by making use of an electro-optical effect. As a result, if a phase modulation voltage of 6 V is impressed at an optical output of 20mW, a minimum line width of the oscillation spectrum of 600kHz is obtained. When a reflected and diffracted beam is in an opposite phase, the line width of the oscillation spectrum is expanded to 15MHz. A monolithic integration-type DBR-LD where a modulator is integrated can be used for a coherent communication system.
