Title: Opening and closing body controller
Inventor: KIKUTANI KAZUO
IPC: H02P29/02
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To judge a load sensing state in a constant load value by making it difficult to influence the occurrence of an event influencing torque of an opening and closing machine. SOLUTION: A temperature detection means 5 detects the temperature of a DC motor M. An opening and closing machine voltage detection means 8 detects a voltage value supplied to the DC motor M. An outside voltage value detection means 17 detects supplied outside power source voltage. A reference voltage value corresponding to a previously stopping load sensing torque is set on a control means 10, and when the detection voltage value of the opening and closing machine voltage detection means 8 reaches the reference voltage value, the DC motor M stops. Since the reference voltage value is corrected by the detected temperature of the DC motor M and the outside voltage, even when temperature and voltage fluctuation occur, stop control is performed by always constant load sensing torque.

IPC: G01F1/32
Filed: 2000-03-16
Abstract: PROBLEM TO BE SOLVED: To eliminate influence of the vibration of piping or the like in a vortex flowmeter which is adapted to detect an alternating differential pressure attributed to a vortex from the vibration of a vibrator. SOLUTION: Measuring chambers 5-1 and 5-2 are bored from both sides at the central part of a vortex generation body 3 fastened on the diameter of a body 1 in the axial direction thereof and pierce mounting seats 2-1 and 2-2 to be opened outside. Vibration sensors 6-1 and 6-2 are inserted into the measuring chambers 5-1 and 5-2 and fastened overhung in such a manner that the pressure receiving surfaces of vibrators 6-1c and 6-2c are in the same direction. Lead ports 4-1a, 4-1b, 4-2a and 4-2b arranged in pairs to communicate with the measuring chambers 5-1 and 5-2 are opened in both sides of the vortex generation body 3 so that changes in alternating pressure owing to a vortex act oppositely on the vibrators 6-1c and 6-2c. As a result, vortex signals with the phase thereof opposite to each other are outputted from the vibration sensors 6-1 and 6-2.  The vibration attributed to a disturbed vibration acts in the same direction and a vibration signal of the same phase is outputted. A difference, taken between outputs of both the vibration sensors, allows the doubling of the vortex vibration component thereby obtaining a signal with a disturbed vibration component offset.
