Title: Fluid pressure elevator
Inventor: SHUDO KATSUHARU
IPC: B66B9/04
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal negative pressure even while stopping of a car before traveling as well as while traveling of the car by limiting a speed command value of car speed to a value smaller than rated speed at the time when a detected value of fluid temperature or both of a pressure detected value and a temperature detected value come to be lower than a specified value. SOLUTION: Speed control of a motor 4 is carried out to reduce a flow rate of a fluid pressure pump 3 by changing a speed command value to a passenger cage 1 when lowering of pressure is detected by pressure detectors 20, 21. Consequently, it is possible to make pressure of the fluid pressure pump 3 higher than a set value and furthermore, it is possible to raise pressure of a fluid pressure cylinder 2, and generation of negative pressure is prevented. Additionally, in the case when generation of abnormal negative pressure is predicted, temperature of fluid is detected before lowering drive traveling, and in the case when its detected value is higher than previously set critical set temperature, it is regarded possible to carry out normal traveling and speed command is made a rated speed command value. Additionally, in the case when the detected value of fluid temperature is lower than critical set value temperature, a speed command value is output by lowering it lower than rated speed.

Title: Inclination angle detector
Inventor: SHIMURA KIKUO
IPC: G01C9/10
Filed: 1986-11-18
Abstract: PURPOSE:To obtain an inclination angle detector having high accuracy by converting the displacement of a core caused by inclination, to the quantity of electricity by a coil being around a housing. CONSTITUTION:A magnetic fluid 3 congregates in the periphery of a magnetic pole of a core 2, therefore, the core 2 floats up from a guide groove surface 6 of a housing 1, and when the housing 1 is inclined, said fluid moves freely to the lowest position of the groove surface 6 curved by the gravity. When the housing 1 is inclined by an angle theta from the horizontal as shown in a figure (b), the core 2 and the fluid move to the lowest position and displaced from a reference position 10, and an output corresponding to this displacement 11 is obtained from a coil 4. When this displacement 11 and a radius of curvature of the groove surface 6 are denoted as (d) and R, respectively, d=thetaR is formed. On the other hand, the inductance of the coil 4 is varied linearly against the displacement (d). Therefore, by detecting the variation quantity of the coil 4 by a detecting circuit, the displacement (d) can be derived. Accordingly, by the radius R and the displacement (d), an inclination angle theta of the housing 1 is detected.
