Title: Production of metal hydride
Inventor: MORIWAKI YOSHIO
IPC: F17C11/00
Filed: 1986-02-19
Abstract: PURPOSE:To remove carbon from a metal hydride alloy and to obtain a metal hydride giving high-purity hydrogen, by occluding hydrogen in a metal hydride alloy and reducing the pressure under heating. CONSTITUTION:An alloy for forming a metal hydride capable of reversibly occluding and releasing hydrogen, such as alloy of rare earth metal, Ti, etc., is heat-treated to improve the uniformity of the alloy phase and hydrogen is occluded in the alloy. The hydrogen-occluded alloy is depressurized under heating to effect the removal of hydrogen. Carbon component in the alloy is reacted with hydrogen to form methane, which is removed from the alloy by degasification treatment. Accordingly, formation of methane can be suppressed and hydrogen having improved purity can be produced by purifying hydrogen gas using the alloy obtained by the above process.

Title: Boom protector for mechanical type continuous unloader
Inventor: SUWA HIDEYUKI
IPC: B65G67/60
Filed: 1988-02-17
Abstract: PURPOSE:To make the torque of a horizontal boom controllable within an allowable value by relieving the oil pressure of a turning motor by means of the output of a sensor detecting an angle made by perpendicularity and a vertical boom at the projection surface of the vertical boom from one end of the horizontal boom. CONSTITUTION:When a supplier 24 receives force F, torque is acted upon at a horizontal boom 11, and a vertical boom 10 at its projection surface from one end direction of the horizontal boom 11 generates the angle of a thetaVS angle against the direction of perpendicularity 14. And the thetaVS angle is decided by the torque MH of the horizontal boom 11 in spite of angles thetaV and thetaH, so, seeking this can be done. Meanwhile, when the value of a sensor 15 has surpassed an allowable value and an electromagnetic valve has been opened by means of an output signal from a control board 13, the boom 11 turns toward the opposite direction from that of the operation of force F and the boom 11 follows after force F, because oil flows, in spite of pipings 17, 18, from the side of high pressure to the side of low pressure or the side of a tank 26 and the oil on the side of high pressure flows out. Accordingly, more than the fixed quantity of torque is not given to the boom 11, and a safe protection can be accomplished.

Title: Temperature gradient compensating device
Inventor: TANAKA MINORU
IPC: H03F1/30
Filed: 1989-02-15
Abstract: PURPOSE:To increase the freedom degree for designating of a circuit without complicating the circuit constitution by discriminating the temperature gradient direction based on the polarity and its level value of the unbalanced voltage of a bridge circuit consisting of a heat detection means having a temperature coefficient and controlling a heat source set in the lower temperature direction for compensation of the temperature gradient. CONSTITUTION:In case the heat generating source of a circuit set in an area 1 having its temperature to be controlled is included in a part shown by a broken line, each detected resistance has its highest level at Ra near the heat generating source owing to the temperature difference caused by a temperature gradient. Meanwhile the temperature of other detected resistances are not increased so much and therefore the resistance values of them are not increased. Thus the balance conditions of a bridge circuit are lost and the unbalanced voltage is produced at the input of a detecting circuit 3 so that the plus polarity is secured at a joint (b). The circuit 3 send the polarity and the level value as necessary of the unbalanced voltage to a control circuit 4. The circuit 4 judges to increase the temperature of a heat source H3 for elimination of the temperature slope owing to the plus polarity of the joint (b). Then the circuit 4 controls the output side so as to supply a current to the source H3. Thus a complicated temperature compensating circuit is not required and the circuit designing variation is improved.
