Title: Low pressure lubricating device for steam turbine
Inventor: SUZUKI TOKUICHI
IPC: F01D25/24
Filed: 1982-10-18
Abstract: PURPOSE:To improve the operatability of lubrication, by connecting the leg part of a low pressure casing and a horizontal joint surface flange in one with a hollow material, while attaching a grease nipple and a check oil plug both to the flange, and making a slide surface lubricatable without removing a lagging. CONSTITUTION:A low-pressure external, lower half casing 5 grows large due to a temperature rise but if this elongation will not be smoothly done, there is a case that operation for a turbine often fails to perform so that, in this method, a lubricating groove 22 is trenched into the lower part of a leg part 21, through which lubrication takes place, thus the casing 5 is made so as to be smoothly elongated. At this time, the leg part 21 of the low-pressure external lower half casing 5 and a horizontal joint surface flange 3 are connected together with a hollow material 29 whereby lubrication is made so as to be done on a slide surface from a grease nipple 23a at the side of a horizontal joint surface flange 30. With this, the lubrication can be carried out without removing a lagging 18 and after oiling is all over, oil inside the hollow material 29 drops down naturally due to its dead load, thus automatic lubrication takes place for the slide surface 27 and operatability in time of lubrication is well improved.

Title: Automatic controller for reaping height of reaping and harvesting machine
Inventor: SATOU SHIGEO
IPC: A01B63/00
Filed: 1981-11-10
Abstract: PURPOSE:To suppress improper elevation control and to stabilize reaping height control by inputting the last detected value to an arithmetic mechanism instead of the current value when the current value detected by a sensor is abnormal. CONSTITUTION:A mechanism 13 calculates the mean value of plural detected values obtained by a sensor 12, and a mechanism 14 elevates and lowers a reaping part automatically on the basis of the mean value of the mechanism 13 so that reaping height is within a set range. When a detected value by the sensor  12 is abnormal, a mechanism 28 inputs the last detected value to the mechanism 13 as a substitute for the current abnormal detected value. Consequently, large variation in mean value is suppressed even under the influence of disturbance, thus stabilizing the reaping height control.
