Title: Method and apparatus for measuring extent of deformation of plastic sheet sample due to temperature and humidity change
Inventor: SAKAMOTO AKITO
IPC: G01B11/16
Filed: 1981-02-03
Abstract: PURPOSE:To increase the measuring accuracy of the distribution of expansion due to temperature and humidity at an external circumference of a sheet sample and to simplify the measuring method, by setting a reference part of the sheet sample and directly measuring the position of the external circumference with an image sensor. CONSTITUTION:An external circumference of a sample 1 is irradiated concentratively by a projecter 7 through a through-hole 6 provided to a supporting stand 5 to pick up an image at an image sensor 8. The external circumference A of the picked-up sample 1 is enlarged and the image is formed on a number of photodetectors. Thus, the output of the detector 9 picking up the sample is low, while the output of the detector 9 receiving the light of the projector 7 is high, and this step difference corresponds to the position of the external circumference A. The output of the image sensor 8 is inputted to a driving circuit 10, where the position of the A is calculated, and the result of calculation is inputted to a calculation circuit 12 through an amplifier 11 and digitally displayed on a counter 13. Thus, the distribution of expansion due to temperature and humidity for the external circumference can simply be measured with high accuracy.

Title: Optical recording method
Inventor: TOMITA YOSHINORI
IPC: G11B7/00
Filed: 1986-01-29
Abstract: PURPOSE:To permit optical writing with a small-sized and lightweight semiconductor laser by irradiating IR rays of a specific wavelength on a recording layer contg. a polydiacetylene deriv. compd. and >=1 kinds of the compds. expressed by specific formulas to discolor the irradiated part thereof. CONSTITUTION:800-900nm IR rays are irradiated according to recording information on the optical recording medium having the recording layer contg. the polydiacetylene deriv. compd. and >=1 kinds of the compds. expressed by formula I or formula II (expressed as polymethylene compd.) to discolor the irradiated part of the recording layer. Input information is imaged through a control circuit, semiconductor laser and optical system onto the prescribed position of the optical recording medium having the recording layer for blue - dark colors. The polyacetylene deriv. compd. existing at the imaging point does not absorb the laser light of said wavelength but the polymethylene compd. generates heat by absorbing said light. The generated heat is transmitted to the polyacetylene deriv. compd. adjacent thereto and the compd. discolors to red. The optical recording by the color change in the recording section on the recording layer is thus made possible according to the input information.

Filed: 1984-01-31
Abstract: PURPOSE:To reduce the influence of the shape of a detect and perform detect detection with high precision by comparing signals of picture elements at positions in the same radial direction as to different nearby radial lines of an image of an inspected part which nearly forms a surface of rotation. CONSTITUTION:A lighting device 2 illuminates a bottle mouth part 1a and its optical image is photographed by a CCD camera 4. Signals of a prescribed number of picture elements which are positioned along radial lines OA, OB, OC,... running through the center O of a video and within a prescribed radial range (chain lines R1-R2) are read out as one group of signals. The signal of each pitcture element is converted into a binary signal to count the numbers of values ''1'' in every predetermined small range of OA, OB, OC,.... When the counted value is not within a prescribed range, the 1st discrimination signal is ''1''. Then, the difference between signals of picture elements which are on two adjacent radial lines and nearly equal in radial position is calculated and then converted into a binary signal. When the sum of those binary signals exceeds a prescribed value, the 2nd discrimination signal is ''1''. When the 1st and the 2nd discrimination signals are both ''1'', it is judged that the bottle has a defect, and the bottle is rejected.

Filed: 1999-01-25
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device which assures much improvement in the access time. SOLUTION: In a semiconductor memory device introducing a virtual ground system, when data is read in the serial read system from a selected memory cell MC1, the source line VSL1 of the selected memory cell is set to the ground level. This source line is set previously set to the ground level in the preceding cycle. Thereby, when the source line of the selected memory cell is set to the ground level, the level of the bit line (drain of the memory cell MC2) BL2 adjacent to the source line is prevented from being lowered by coupling, and high speed access time can also be realized. Moreover, a virtual ground is additionally provided to allow the flow of an interference current and thereby an interference current flowing to the virtual ground connected to the selected memory cell can be reduced. Accordingly, an interference current flowing into the virtual ground can be reduced to realize a high speed access time.
