Title: Desk-top type infrared measuring apparatus for moisture
Inventor: SAITO YASUO
IPC: G01N21/359
Filed: 1990-10-24
Abstract: PURPOSE:To enable execution of highly accurate measurement without necessitating warming-up substantially, by reducing a drift of a measured value by conducting calibration automatically. CONSTITUTION:A calibration plate 8 having a small hole 6a formed is disposed on the sample setting surface side of a sample table 6, while a photodetector element is disposed inside the small hole 6a of the calibration plate 8. The presence or absence of a sample S is detected by detection of light by the photodetector element, and calibration is executed by the calibration plate 8 in a state wherein the sample S is absent. When measurement of a moisture value for the sample S is not executed, that is, when a sample vessel is not set on the sample table 6, the photodetector element is detected through the small hole 6a of the calibration plate 8 and the calibration is executed by the calibration plate 8. Before the measurement for the sample S is executed, accordingly, the calibration is always executed automatically, and therefore a correct measured value is obtained immediately after each calibration. According to this constitution, execution of highly accurate measurement is enabled without necessitating warming-up substantially.

Title: Receiver circuit
Inventor: MINAGAWA CHOZABURO
IPC: H04L12/40
Filed: 1988-11-11
Abstract: PURPOSE:To attain stable signal transmission at a high speed on a bus line by keeping a branch line of a receiver circuit independently of the signal reception to a prescribed potential interrupted electrically from the bus line so as to reduce the effect of the branch line independently of the signal transmission. CONSTITUTION:A receiver circuit 40 is connected to a bus line 7 via a branch line 21 and a rectifier element 30. When a data input control signal IE in the receiver circuit 40 is at a nonselection level, that is, an L level, a switch 43 is thrown to the position of a power potential V and since the branch line 21 is charged to a power potential level via a resistor 42, the rectifier element 30 is electrically isolated independently of the level of the bus line 7. As the result, the bus line 7 and the branch line 21 are isolated electrically and the entire capacitance of the branch line 21 when viewed from the bus line 7 is nearly the capacitance of the rectifier element 30. That is, the capacitance of the branch line being 10-15pF in a conventional constitution is reduced to nearly 1/5 as 2-3pF equivalently.

Title: Displacement detecting apparatus
Inventor: KOBAYASHI YUJI
IPC: G01C19/00
Filed: 1990-10-23
Abstract: PURPOSE:To detect the angular displacement with high accuracy by an apparatus simple in structure, compact in size and light in weight, by rotating a supporting member together with a movable member. CONSTITUTION:When an object mounted on the apparatus is rotated, the rotation of a container 4 is controlled only by a servo motor 2. The container 4 is not rotated to an outer case 1 and therefore, the positional relationship between the container 4 and outer case 1 is not changed. A float 8 below a magnetic needle 8c has a tendency to keep the original directional position by inertia, and the water around the float 8 does not receive resistances from an inertial body. As a result, the water rotates relatively to the outer case 1 and the container 4, and the float 8 shifts from an original reference position. The detecting quantity of light by shift detecting means 14a, 14b of an optical detector of the container 4 is increased/decreased at a boundary line where the float 8 is transparent and not transparent. When the output difference becomes not smaller than a predetermined value, a control circuit 18 drives the motor 2, thereby rotating the container 4 in a direction of the shift of the float 8. If the output difference becomes not larger than the predetermined value, the motor 2 is stopped to stop the rotation of the container 4. The float 8 is returned to the reference position. The rotating amount at this time is detected by a potentiometer 19, so that the angular displacement is detected.
