Title: Magnetic encoder
Inventor: MIYAMOTO TAKEHIKO
IPC: G01D5/245
Filed: 1986-11-07
Abstract: PURPOSE:To obtain a thin, small-sized encoder by providing a body of rotation which has one line recording zone where all pieces of information are written between two adjacent position information recording positions, and obtaining a necessary position signal output in this recording zone. CONSTITUTION:A magnetic head consists of a sensor A1 for A-phase signal detection and sensors B1 and B2 for A2- and B-phase signal detection arranged at prescribed intervals, and they are arranged at prescribed distances. The outputs of the sensors A1, etc., and B1, etc., which are read out by the magnetic head at constant-period H and L levels are inputted to logic circuits 7a and 74 and outputted as an A- and a B-phase signal. Consequently, respective phase signals are obtained even when the write position of, for example, reference position (Z position) information is read out. Further, the outputs of the sensors A1 and B1, and A2 and B2 are supplied to circuits 73 and 72, which output signals Z1 and Z2 to a circuit 75 to generate a signal Z, thereby outputting the signal Z corresponding to the Z position information. Therefore, three signals A, B, and Z are led out with one recording line.

IPC: A47B81/06
Filed: 1990-10-01
Abstract: PURPOSE:To reduce the load of a motor and to reduce a space by permitting the motor to move a slide plate back and forth and opening/closing a door mainbody with the link motion of a link mechanism composed of three connecting plates. CONSTITUTION:One end of the connecting plate A13 is axially-connected with the door 11 and the other end of the connecting plate A13 is axially-connected to the connecting plate B15. One end of the connecting plate C16 is axially- connected to the axially-connecting part of the connecting plates A13 and B15 and the other end of the connecting plate C16 is provided to a case body 12 and it is axially-connected to the slide plate 17. When the slide plate 17 is slid by the motor or the like, the door mainbody 11 turns and opens by the ink motion of the link composed of the connecting plates A13, B15 and C16. When the length of the connecting plate C is changed in accordance with the size and weight of the door mainbody 11 in such operation, the component of lifting up force for closing the door mainbody 11 applied to the connecting plate A13 becomes small. Thus, the load of the motor can be reduced and the space can also be reduced.

Title: Rare earth element-transition metal element target and its production
Inventor: MATSUMOTO SHUNICHIRO
IPC: C23C14/34
Filed: 1986-11-06
Abstract: PURPOSE:To manufacture a product minimal in internal defects and oxygen content and hardly causing cracks and breakage at the time of machining, by subjecting a mixture of a rare earth element-transition metal element alloy powder and a powder of a transition metal element to hot compaction at the prescribed temp. CONSTITUTION:A powder in which the rare earth element-transition metal element alloy powder having rare earth metal element content higher than that in the desired composition and the transition metal are regulated so that desired composition is reached and then are mechanically mixed is prepared. This powder is subjected to pressure sintering in an inert gas or in vacuum in the temp. range between the solidus temp. and liquidus temp. of the mixture, so that a liquid phase is formed among powder-constituting grains and then this liquid phase is infiltrated into the voids among the grains so as to join the grains. Although this joining phase is composed of a (transition metal)2(rare earth metal)- or (transition metal)3(rare earth metal)-type intermetallic compound, the transition metal remains in the greater part of a sintered compact and it contributes toward the improvement in the mechanical strength of the sintered compact. Moreover, the rare earth element-transition metal element powder is more difficult to be oxidized than the rare earth metal as a simple substance.
