Title: Atomic absorption spectrophotometer
Inventor: KOJIMA SEIJI
IPC: G01N21/31
Filed: 1990-04-27
Abstract: PURPOSE:To automate the dilution or measuring operation of a sample to be measured by sucking several kinds of solutions containing the sample by the indication from a control part to mix them and supplying the liquid mixture to the sample injection part of an atomizing part. CONSTITUTION:When measurement is carried out according to a standard addition method, at first, the first standard sample value (containing 0) is taken in a control part 14. In an automatic sample changer 4, respective predetermined amounts of a dilution liquid, a standard sample and a sample to be measured are successively sucked in a tube 20 so as to interpose a small amount of an air layer between them and air is sucked until the dilution liquid, the standard sample and the sample to be measured enter a mixing part 22 to mix all of them. Thereafter, only a small amount of the mixed sample solution is discarded to a cup 26 and, thereafter, a necessary amount of said solution is emitted to the capillary of an atomizing part 2 from the tube 20 to be measured and the tip of the tube 20 is washed to prepare the tube for the next measurement. A standard sample of a next set value is taken in and measurement is repeated in the same way and, when the measurement based on all of scheduled standard sample values is completed, a calibration curve is prepared and concn. is calculated.

Title: Control apparatus of panoramic x-ray imaging apparatus
Inventor: MACHIDA TORU
IPC: A61B6/14
Filed: 1987-05-09
Abstract: PURPOSE:To always obtain a sharp photographing image, by performing position control for holding the relative distance between the position of the tooth row of a patient at the time of photographing and an X-ray source within a definite minute range enabling X-ray tomographic imaging using a shape plate similar to the tooth row of the patient. CONSTITUTION:The point P on the tooth row of a patient is projected on the point B on a cylindrical drum 5, which can rotate around a fixed shaft O3 having a film wound around the surface thereof, from an X-ray source 4. A chair 2 and a table 6 are connected by a belt so as to rotate in the same phase. In a shape plate 7, the relational position of a tooth shape 1 to an axis O1 is made same to that of the shape plate 7 to the axis O2 of the table and phase relation is also made same. The shape plate 7 on the table 6 also rotates by the rotation of the chair 2 but a table 3 parallelly moves so that the point P' on the shape plate 7, that is, an X-ray irradiation position becomes a constant distance from a spatially stationary valve 11. Since the tooth row 1 of a patient and the shape plate 7 rotate synchronously, PP' is regarded to be always constant. Therefore, PO3=L and PB become constant and, as a result, the condition of sharp panorama tomographic imaging is satisfied.

Title: Approximation processing system for pattern
Inventor: OUCHI SATOSHI
IPC: G06T3/00
Filed: 1987-05-12
Abstract: PURPOSE:To obtain a pattern which regenerates more faithfully the features of an original pattern by correcting a error between position information on each extracted part undergone an averaging process and the position information on the original pattern by scattering said errorevenly on a line pattern produced from the position information undergone averaging process and producing an approximate pattern based on the corrected position information. CONSTITUTION:The features of an original pattern are extracted via the broken line approximation of all curvature functions and an approximate error correcting part 4 corrects an approximate curve based on the approximate curve obtained by said extraction of features and the original pattern. In other words, the positions shifts DELTAx and DELTAy are obtained between the end point of the approximate curve and the original pattern. Then these shift values DELTAx and DELTAy obtained at the end point are distributed proportionally in response to the start point and each flexure point. Thus the position of each flexure point is corrected. In such a way, the position correction is carried out, based on the approximate error between the flexure points or intersecting points of approximate curves. Thus it is possible to obtain the approximate curves that regenerate more faithfully the features of the original pattern.

Title: Display unit
Inventor: SHIMODA YASUHIDE
IPC: G06F3/14
Filed: 1977-09-21
Abstract: PURPOSE: To prevent the temporary distrubance of the display state on the display screen by erasing temporarily part of the character displayed on the scanning line of the CRT screen.  
     CONSTITUTION: Inverter circuit 10 and AND circuit 11 are installed. When computer 1 reads out character information "Y" memorized in memory 4 in the state under which character information "X" is displayed on scanning lines (a)W(f) of the screen, area (a) of the scanning line of "X" displayed on CRT9 is erased temporarily. In other words, circuit 10 reverses the output of process circuit 2, so circuit 11 functions to cut off temporarily the introduction of the video signal of video signal generator circuit 8 into CRT9. On the other hand, when the read and write signals given from computer 1 are completed, the output level of circuit 10 becomes contrary to the above. Accordingly, the video signal is applied to CRT9, and the normal character information is displayed on scanning lines (a)W(f)
