Title: Grinding abnormality detection device
Inventor: NIIHARA YOSHIMI
IPC: B23Q17/09
Filed: 1985-05-21
Abstract: PURPOSE:To permit an accurate detection of an oscillated grinding state by providing a constitution that a grinding state detection means produces a decision signal after removing only an output signal corresponding to a hole by a removing means. CONSTITUTION:Every time a grinding stone 10 grinds a workpiece 3, an eddy current sensor 9 detects non-contactingly an oscillated grinding state of the surface to be ground 1 of the workpiece 3. A lubrication hole detection unit 12 detects an output signal corresponding to a portion of a lubrication hole 2 of the workpiece 3 and a lubrication hole masking unit 11 operates to remove the output signal corresponding to the lubrication hole 2 so that only an oscillated grinding signal is taken out. The grinding signal is applied to a grinding state detection means 14. A detection decision unit 16 compares and decides an amplitude and a period of the oscillated grinding signal and the decision signal are sequentially applied to a following detection decision temporary memory 17. When a workpiece completes one rotation, an oscillation signal is erased and a value detected at a final grinding process is produced from the memory 17 through a detection decision unit 20.

Title: Zoom lens
Inventor: TSUJI SADAHIKO
IPC: G02B13/04
Filed: 1986-05-14
Abstract: PURPOSE:To shorten the total length of a lens system, to reduce the size of the lens system and to simplify the mechanism of a diaphragm by arranging a fixed diaphragm between two lens groups having prescribed refractive power values and to be moved at the time of variable power operation. CONSTITUTION:The 1st group 1 is non-linearly moved to the image face side and the 2nd group 2 is linearly moved to the object side as shown by arrows while changing the interval between both the lens groups 1, 2 to execute variable power operation from a wide angle end to a telephoto end. In many cases, the diameter of the lens in the 1st group 1 is determined by the incident height of inclined light beams at the wide angle side. Therefore, the incident height of the inclined light beams to the 1st group 1 is reduced as low as possible by arranging the diaphragm 3 close to the 1st group 1 as near as possible to reduce the diameter of the lens in the 1st group 1. Although the diameter of the lens in the 2nd group 2 is increased in said constitution, the lens diameter of the 2nd group 2 is not increased so much as compared to the 1st group, and when the lens system is applied to a video camera, the increase of the lens diameter is small because the size of a screen is comparatively small, and troubles are scarcely generated on practical use.
