Title: Image pickup device for endoscope
Inventor: NAGASAKI TATSUO
IPC: H04N5/232
Filed: 1983-10-03
Abstract: PURPOSE:To enable display of the actual size of the desired position of the image, which is displayed on an image plane, on the image plane by providing a liquid crystal shutter which is vertically or laterally bisected with the plane inclusive of the optical axis as a boundary and can control light shielding of each one thereof in the pupil position of the objective lens of an imaging optical system and detecting a distance. CONSTITUTION:A liquid crystal shutter 29 is provided in the pupil position of an objective lens 5 of an endoscope as a distance measuring means for detecting the distance up to an object in addition to an illuminating means and an observing (image pickup) means. The voltage to be impressed thereto is controlled to bisect the shutter 29 in a lateral direction and to make each one thereof into the shielded state. The lateral deviation from the focusing state is detected from the signal output detected with each photodetector 8 of a solid state image pickup element 6 in said state and the actual distance of the object is determined. The expansion ratio of the image is determined by utilizing the similarity relation from said distance and the distance between the two points marked on the display image plane is displayed as, for example, 45mm. at the corner, etc. of the display image screen.

Title: Mixing device
Inventor: JIYOOJI KINGUSUREI
IPC: B01F27/96
Filed: 1989-07-19
Abstract: PURPOSE: To form a high-velocity flow by rotatably mounting a hollow elongated shaft about a longitudinal axial line and disposing a dividing means for dividing the interior of a vessel to two zones. CONSTITUTION: When a motor 32 operates, a shaft 22 rotates and a propeller 56 agitates and mixes a mass of granular materials and fluid within a region 38, thereby forming sludge or slurry. This sludge or slurry moves upward and simultaneously an impeller 34 is rotated by the rotation of the shaft 22 and the vanes of the impeller 34 forcibly send the slurry of the granular materials and the fluid outward from the shaft, by which the low pressure region is generated around a free end 28 within the mixture of the solids and the fluid. When the impeller 34 rotates, the slurry is sent outward toward the side wall surface of the vessel 20 and the movement of the slurry by the rotation of the propeller 56 is meshed with each other to move the slurry upward. As a result, the recirculation of the solvent is smoothly carried out.

Filed: 1985-08-22
Abstract: PURPOSE:To enable a high-speed operation by applying an electric field in the direction parallel to the hetero junction interfaces with a voltage applied in the direction perpendicular to the hetero junction interfaces, thereby enabling a current to flow in the direction perpendicular to the hetero junction interfaces. CONSTITUTION:When a voltage is applied between electrodes 6, 7 with a voltage applied between electrodes 4, 5, an electric field is applied in the direction parallel to each hetero junction interface, causing a two-dimensional electron gas 8 and a two-dimensional positive hole gas 9 to be accelerated in the direction parallel to the hetero junction interfaces and to be heated. At this time, the means energy increases and a hot condition is provided. As a result, electrons accumulate in the conduction bands of GaSb layers 2 from the two-dimensional electron gas 8 over DELTAEc, and simultaneously positive holes accumulate in the valence bands of InAs layers 1 from the two-dimensional positive hole gas 9. As a result, the curvatures of the conduction bands and the valence bands of GaSb and InAs become small, and the InAs-GaSb superlattice transforms in phase into a semi-metal wherein a sub-band E1 of the electrons ranging over the all InAs layers 1 and GaSb layers 2 and a level HH1 of the heavy positive holes are existing. With this, a current flows between the electrodes 4, 5.

Abstract: PURPOSE:To prevent fault of installation or defective processing by providing a shift register, a change detection pattern and a change discrimination means or the like so as to detect accurately the change timing of a process status while excluding the effect of an external disturbance. CONSTITUTION:A DI history table 2 updates and stores a signal fetched at a prescribed sampling period by a change point detector 1 into a shift register having a bit number corresponding to a prescribed sampling number as a time series binary pattern signal. Moreover, the correct reference change state of the process status in a prescribed sampling period width before and after the process status change point is preset to an ON-change detection pattern 4 and an OFF-channel detection pattern 5. Then the master pattern 3 extracts only the signal required to collate the pattern 4 or 5 among the input pattern signals stored in the table 2. Then the pattern is collated for each content update of the register via the device 1 and when they are coincident, the change detection signal is outputted to detect accurately the process change timing.

The comparator 8 binarizes the output of the sensor 7 by a predetermined threshold voltage, outputting the timing of the change of the binary signal as a trigger signal to a buffer 9. An output of the counter 6 is fed to the buffer 9. The buffer 9 reads the integral counting value and outputs the same to an operating processor 10. The processor 10 operates the average of the input counting values, based on which can absolute position of the center of the groove 2 in a widthwise direction is output as an angular information theta.

Filed: 1991-07-25
Abstract: PURPOSE:To prevent out-of-focus caused by parallax by continuing light projecting action when a calculated object distance shows a shorter distance than a specified value after completing the light projecting action necessary for calculating the object distance. CONSTITUTION:Light for range-finding, which is projected from a light projecting element 2 and focused by a light projecting lens 1, is projected toward an object 20. Reflected light reflected on the object 20 is formed into an image on the light receiving surface of a light position detecting element 8 through a light receiving lens 9. Then, a photoelectric current in accordance with the light receiving position of the reflected light on the PSD 8 is supplied to an AFIC 7. When a 1st release switch 6a is turned on, a CPU 5 causes an LED 2 to project light specified number of times to perform range-finding first. When the output result of the AFIC T is within the specified distance, the light is projected after changing the light projecting state of the LED 2 this time. Since the object 20 is in a close photographing area at such a time, a light emitting state is changed to be such a state that the reflected light can be confirmed within a finder, for example, duty ratio is made higher.

Further, the measurement of the standard material in which the deteriorated layer is removed is repeated, the attenuation coefficient alpha0 of the wave at the surface layer of the standard material is calculated from the obtained two received sound pressures, and standardization (alpha-alpha0) value is used as an evaluation reference to the deterioration of the material. Thus, the deterioration of the material can be non-destructively quantitatively measured and evaluated.
