Title: Digital phase detector
Inventor: OSAWA TOMOYOSHI
IPC: H04L27/00
Filed: 1988-03-14
Abstract: PURPOSE:To decrease the capacity of a mapping ROM by multiplying 2-axis digital signal subjected to orthogonal detection by a factor of 2K and obtaining a phase angle corresponding to a 2-axis vector of each bit length from a storage device when the value is larger than 2N<-2> (N is bit length). CONSTITUTION:The 2-axis digital signal in N-bit length subjected to orthogonal detection is inputted respectively to multipliers 10, 11, where a factor of 2K is multiplied with the digital signal whose bit length is N. As the result of multiplication it is outputted to a level detector 2 as the 2-dimensional signal in N-bit length and outputted to a storage device 4 as the 2-dimensional signal in M-bit length (M<N) from high-order bit. When either of the absolute value of the signals exceeds 2N<-2> in the level detector 2, a phase angle corresponding to the 2M-bit vector comprising M-bit from the most significant bit is obtained from the storage device 4.

Filed: 1993-03-18
Abstract: PURPOSE:To improve distance detection accuracy by changing images which are picked up to digital images, reading the data for compensating shading corresponding to each picture element from a memory and then multiplying it, and then outputting it as already compensated data. CONSTITUTION:Images which are picked up by left and right CCD cameras 11a and 11b are converted by A/D converters 32a and 32b, contrast is increased by LUTs (Look-Up Tables) 33a and 33b, characteristics are compensated, and then the compensation ratio inside the memories 35a and 35b for compensating shading is multiplied by multipliers 34a and 34b for each picture element to be specified by an address control part 86. The multiplied and compensated data are stored in image memories 36a and 36b. The peripheral part of cameras 11a and 11b becomes darker than the optical center due to shading phenomenon of an optical system. Therefore, by measuring the brightness for each region previously and then determining the compensation ratio, a uniform target can be expressed accurately in an entire region and distance can be calculated accurately by a city block distance calculation part 40.

Filed: 1986-03-19
Abstract: PURPOSE:To perform uniform flat etching, by recovering Si, which is eluted from an Si substrate on a stage electrode, thereby preventing the increase in Si concentration of an etching liquid. CONSTITUTION:An etching bath 1 is filled with an etching liquid 5. The etching speed of a substrate 2 is controlled with a voltage, which is applied between the Si substrate that is sucked-up with a vacuum and fixed in a central recessed part 8a of a disc shaped stage 8 and a mesh electrode 9. Since the stage 8 is rotated by a motor 12, the etching liquid performs conventional flow as shown by arrows. The potential of the etching liquid in the vicinity of the substrate 2 is detected by a reference electrode 4 through a glass capillary 10. The potential of the substrate 2 is controlled to the side of an anode from a natural potential. The potential of a stage electrode 11 made of Ta at the outer surface part of the stage 8 is controlled to the side of a cathode from the natural potential. Then, Si which is eluted from the substrate 2, is reduced and deposited on the electrode 11. Therefore, the increase in Si concentration of the etching liquid 5 can be prevented. Then the uniform and flat etching can be performed, and a large amount of Si can be etched with the same etching liquid.

Abstract: PROBLEM TO BE SOLVED: To inform a user of abnormality of the mounting state of a container when it is abnormal by providing a means detecting that the mounting state of the detachably mounted container is not proper and a means informing abnormality at the time of detecting abnormality by this. SOLUTION: At the time of starting automatic operation, whether the container is normally mounted or not is judged first (S1). At this time, the output of an element for detecting the expanded height of bread dough is examined. Namely, in the case where the container is mounted shallowly, the container itself floats as the result and this obstructs the incident of light to a photodetective element to make the output of the photodetective element at a high level. When the container is not mounted normally at this time, an abnormality display lamp is lighted to stop operation (S2). Then, a cancelling switch is operated to cancell the abnormality display lamp and after remounting the container, a cooking course is reset by a selecting switch and a start switch is pressed to start automatic operation again.
