Title: Hydraulic controller for automatic speed changer
Inventor: SHIMAMOTO MASAO
IPC: F16H61/00
Filed: 1984-07-17
Abstract: PURPOSE:To reduce the number of solenoid valves for functioning the shift valves thus to reduce the cost by switching the shift valves for controlling the clutch and brake elements in automatic speed changer in sequential operation while corresponding with shift change. CONSTITUTION:Upon provision of a command for changing the speed from third to fourth, solenoid valves 41, 42 will open thus to never produce the control pressure in the first and second control paths 43, 44. Since the working oil has been fed through third control path 45 into the pressure control chamber 35b of fifth shift valve 35 because of speed change in previous stage, the spool 35a of fifth shift valve 35 has not return against a spring. Consequently, a lockup clutch C3 and the first brake B1 will function to shift to the fourth speed. Since the condition of shift valve is sequentially switched through speed change in previous stage, the number of solenoid valves for functioning the shift valve can be reduced.

Title: Optical measuring instrument
Inventor: SHIGEYAMA NAOKI
IPC: G06T1/00
Filed: 1992-06-09
Abstract: PURPOSE:To enable an instrument to automatically follow the unknown shape of a feature line at a high speed by measuring the deviation of a feature point from the center of a picture and applying no acceleration nor deceleration to a machine when the measured deviation is lower than an allowable value, but applying the acceleration or deceleration when the measured deviation exceeds the allowable value. CONSTITUTION:A slit-type sensor 1 supported by a machine 10 emits slit light 2 in the direction crossing a character line 3 and the profile of the light 2 is taken with a camera 14. The picture taken with the camera 14 is fetched 4 and a feature point to be measured is extracted 5. The deviation of the feature point from the center of the picture is calculated 6 and a deviation comparator 7 discriminates whether or not the deviation exceeds a preset allowable value. A machine moving command generator 8 issues a command to always move the machine 10 in a fixed direction at a fixed speed while the comparator 7 discriminates that the deviation is lower than the allowable value. When the comparator 7 discriminates that the deviation exceeds the allowable value, issues a moving command to reduce the deviation. The moving command is transmitted to NC(numerical control) 9 and the machine 10 is made to automatically follow the command.

Title: Image reader
Inventor: HATTORI YUTAKA
IPC: H04N1/19
Filed: 1990-06-07
Abstract: PURPOSE:To read the density distribution of an image having the finer density than the CCD density by forming two types of images on a one-dimensional array photodetector at the positions different from each other just by the half of a picture element pitch every time the polarized surface of an analyzer is coincident with the polarized surfaces of the normal and abnormal beams of a multi-image element. CONSTITUTION:The working of a camera part 3 is explained as follows. That is, the natural light incident vertically on a multi-image element 33 travels in two directions in the element 33 owing to the difference of polarized surfaces. Then the natural light is divided into a normal beam O having a polarized surface vertical to the paper surface where the optical axis is displaced by (d) at emission and an abnormal beam E having a polarized surface within the paper surface. Then two types of images are formed on a one-dimensional array photodetector 34 at the positions different from each other by the half of a picture element pitch every time the polarized surface of an analyzer 32 is coincident with the polarized surface of both beams O and E of the element 33. Thus it is possible to read the density distribution of an image having the finer density than the picture element density of the photodetector 34.
