Title: Commutator type motor having rotation detector
Inventor: KOSHIYOU HIDETAKA
IPC: H02K11/00
Filed: 1978-12-30
Abstract: PURPOSE: To detect the rotational frequency of the motor with a detection coil through an amplitude modulation of the higher harmonic signal applied from an oscillation coil in proportion thereto by rotating tongue pieces constructed integral with the commutator in a magnetic closed circuit including the osicllation coil and the detection coil.  
     CONSTITUTION: Tongue pieces 14 are provided projected from the base of the commutator piece 8. At the position where the tongue pieces 14 are off a detection coil 13, a signal oscillated by an oscillation coil 12 develops in a detection coil 13. As the tongue pieces approach the detection coil, the amplitude of the signal developing in the detection coil 13 decreases. In such a manner, the rotational speed detection part 11 is so arranged that the tongue pieces 14 cross between a magnetic substrate of a magnetic closed circuit covering a shaft 2, a case 1. the magnetic substrate 7, the core of the detection coil 13, the core of the oscillation coil 12, a bracket 6 and the shaft 2 and the detection coil 13. The signal transmitted from the detection coil 13 corresponds to the higher harmonic signal outputted from the oscillator OSC after the amplitude modulation following the rotation. The signal is detected to determine the rotational frequency of the motor.

IPC: B60N2/08
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To movably mount a plurality of rows of seats on the same rail by sequentially operating a slide stopper of a lower stopper mechanism and a lock lever of a seat slide lock mechanism.

Abstract: PURPOSE:To detect a position of a rotor with lower comsumption of power by deciding the position of the rotor through taking out bouncing voltage generated with exciting current for the difference in the inductance of an exciting coil, which is generated in accordance with the position where the rotor stops. CONSTITUTION:To an exciting coil 17 of a step motor, detecting current is applied through changing over from a condition (a), in which switching elements 32 and 33 are turned on, into that (b), in which the switching elements 30 and 33 are turned on. Then, through turning the switching elements 30 and 31 off and the switching elements 32 and 36 on (c), bouncing voltage proportional to the current which has flowed through the coil 17 is generated along a resistor 37. Since the inductance of the coil 17 changes in accordance with a position of a rotor, said bouncing voltage also changes in accordance with the position of the rotor and is able to detect the position of the rotor.

Filed: 1981-10-19
Abstract: PURPOSE:To reduce the diffusion of air diacharged from the hanging-from- ceiling type indoor unit of an air conditioner and make the unit compact in construction and high in performance by reducing the air suction resistance and using an axial-flow fan. CONSTITUTION:An indoor unit is provided with a dew receiving device comprising at the lower side of a heat exchanger 32, a dew tray 33a, and one or more dew receiving plates 33b, and constituted such that air is sucked through the gaps 33c formed between the dew receiving plates 33b and the dew tray 33a. By the above construction, in the present hanging-from-ceiling type indoor unit, suction of air from the lower surface of the unit becomes possible, and hence it is possible to install the unit onto a wall 38 in a state where its back surface is closely contacted thereto. Further, the size of an air filter 37 can be made larger than that of conventional filter and hence the air suction resistance can be reduced. Therefore, a small sized axial-flow fan 31 can be employed as a blower and hence the indoor unit of a small size and a light weight can be obtained. Further, by using the axial-flow fan 31, the reachable range of exhaust air is extended, particularly the room temperature distribution upon heating operation becomes excellent.
