Title: Threshold deciding circuit
Inventor: KAIZUKA SHINJI
IPC: G06T1/00
Filed: 1987-03-19
Abstract: PURPOSE:To remarkably simplify a threshold deciding circuit, by reading out the threshold level corresponding to a notable picture element position from a memory after the level is once stored in the memory and correcting the level by moving it upward or downward by means of a level changing means in corresponding to the designation of the density at the time of reading an original. CONSTITUTION:A ROM 11 for outputting threshold level which inputs levels of picture elements P, Q, R, and S in the vicinity of a notable picture element A and decides at which threshold level the notable picture element is binary coded, is provided. The ROM 11 reads out the threshold level of the notable picture element A from the correlation among the picture elements P, Q, R, and S. With respect to the output of the ROM 11, the process of the density mode designated at the time of reading an original is performed by means of a density switching device 12 in such a way that, when the density mode is designated to 'dark', the threshold level is lowered and, when designated to 'light', the threshold level is raised. In other words, the threshold level is decided by means of the combination of the ROM 11 and switching device 12 and binary signals are produced after the threshold level is com pared with the notable picture element A at a comparator 13. Therefore, this circuit is made smaller in size and simpler in constitution. In addition, this circuit can be changed easily.

Filed: 1994-03-10
Abstract: PURPOSE:To improve the extent of measuring accuracy by enabling the accurate measurement of a peak height and area at each gate time zone after securing a margin to any variation in the peak position. CONSTITUTION:During a gate time zone G1, a measuring gain of concn. signal wave-form is increased from A1 to A2 at a timing t1 just before entering another gate time zone G2. With this increment, this concn. signal wave-form goes up suddenly just after this increase in the measuring gain. In this constitution, as for the concn. signal wave-form (sudden-upping concn. signal wave-form) W1 until it suddenly goes up immediately after the changeover of the measuring gain and meets the first peak, after this concn. signal wave-form W1 is replaced with another concn. signal wave-form (virtual concn. signal wave-form) W2 which may be secured by the measuring gain A1 before the gain changeover, each concn. of N2 gas and CO gas is measured on the basis of the concn. signal wave-form to be measured at both these gate time zones G1 and G2.

Abstract: PURPOSE:To enable measurement of fine displacement whether a surface of an object to be measured is rough or mirror-finished by detecting to clarify whether the surface to be measured is rough or mirror-finished using a laser light. CONSTITUTION:A laser light 1 is oscillated, a quantity of light reflected from a surface M2 of an object 3 is received with a photodetector 9 and a size of the quantity of light is judged by a judging section 8 to identify the surface M2 between rough and mirror-finished surfaces automatically. Then, the photodetector 9 is shifted with a horizontal slide means 11 from a focusing position to input an interfering light into a photoelectric detector 4. When the surface to be measured is mirror-finished, a reference surface is so set by a vertical slide means 13 to be a regularly reflecting surface while a photoelectric signal switch 5 is driven to make a setting so that a photoelectric signal is inputted into a light interference signal processing section 6. When the surface to be measured is rough, the means 13 is driven to be a uniformly diffusing surface and the switch 5 is driven to let the photoelectric signal be inputted into a speckle interference signal processing section 7. Then, the photoelectric signal is processed with the processing section 6 or the processing section 7 and sent to a judging section 8 to measure a displacement.

Title: Rotation detector
Inventor: MIYAMOTO NAOKO
IPC: F16C19/52
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a precise and highly reliable rotation detector even exposed at low-temperature in a cold district by setting the thickness of the elastic magnetic material to a specified value or less. SOLUTION: An elastic magnetic material requires a thickness <=1.5 mm. Namely, when the thickness exceeds 1.5 mm, the reduction in magnetic force of the elastic magnetic material is increased when exposed to a low temperature of about -40 deg.C, resulting in impossibility of measurement or reduction in reliability of measured value. When the thickness is thinner than it is required, the magnetic force necessary for rotation detection cannot be obtained to make a precise measurement difficult. The thickness is generally desirable to be >=0.4 mm. As the component of a matrix constituting the elastic magnetic material together with a magnetism imparting material, those excellent in heat resistance such as acrylic rubber elastomer, fluorinated rubber elastomer, silicone elastomer or the like are preferred.  As the magnetism imparting material for adding magnetism to the elastic material to constitute the elastic magnetic material, ferrite is preferably used.
