Abstract: PURPOSE: To prevent the damage of piping and the leakage of fluid due to an impact, by providing a cylinder for tightening a crawler and a communication passage which is located in the mounting part of the cylinder and can be connected to a pump and by using a spring and fluid pressure to move the cylinder to connect or disconnect the communication passage.  
     CONSTITUTION: A fluid pressure cylinder 8 is conjoined to a crawler-tightening wheel 3 through a support member 7. A spring 9 is provided to push the cylinder 8 in a direction to tighten a crawler. A communication passage 11 between the cylinder 8 and a pump P is provided in the cylinder and its mounting member 1a so that the connection and disconnection of the passage 11 is controlled by the displacement of a cylinder tube 8b which is caused by the spring 9 and fluid pressure. When the tensin of a belt 6 has fallen with the decrease in the pressure of the cylinder 8, the tube 8b is displaced by the spring 9 to connect the parts 11a, 11b of the communication passage 11 to each other to supply a pressurized fluid from the pump P to the cylinder 8. When the belt 6 is tightened to a prescribed tension level, the tube 8b is displaced by fluid pressure to disconnect the communication passage 11.

Abstract: PURPOSE:To shorten an access time without using a delaying circuit and without lowering a bit line to a negative potential, by connecting one end of each bit line to an earth through the drain-source of a transistor whose threshold voltage is about ''0''V, and also connecting the gate of the transistor to an earth. CONSTITUTION:The gate potential of a negative potential obstructing transistor connected to each bit line BL is fixed to an earth (Vss), and Vth of a transistor QB is set to ''0''V (strictly speaking, about +0.1V). When such a transistor QB of ''0''Vth is connected to of a diode of a gate-source short circuit type and used, a transistor Q6 becomes on and is charged from an earth, when the potential of the bit line BL is about to become a negative potential, therefore, as a matter of fact, it does not become a negative potential and helds ''0''V. When a transistor QC is turned on and charged up to about +1V by a sense amplifier SA, the transistor QB becomes off, therefore, this charge-up not obstructed.

Title: Flat exothermic body
Inventor: NOMURA HIROMI
IPC: H05B3/14
Filed: 1990-04-26
Abstract: PURPOSE:To improve the safety of a flat exothermic body by so positioning a conductive ribbon near a conductive elastomer layer as to cover the entire surface thereof, and shutting off an electrode from a power supply when the abnormal heat generation of the conductive elastomer layer is detected from a change in the resistance of the conductive ribbon. CONSTITUTION:Upon occurrence of local heat generation in the conductive elastomer layer 11 of a flat exothermic body 10A, the conductive ribbon R11 of a breaking device 10B covering the entire surface of the layer 11 gives an excessive increase in resistance. At the same time, voltage at the non-reversible input end of an operation amplifier OP becomes lower than voltage at a reversible input end, and a low level output signal appears at the output end of the amplifier OP. Voltage, therefore, drops between the base and emitter of a transistor TR, and a non-conductive state appears between the base and emitter. Consequently, an exciting coil Ry is turned to non-excitation state and a relay contact ry is opened, thereby interrupting power supply from an AC power supply E to the electrodes 12 and 13 of the flat exothermic body 10A. According to the aforesaid construction, the safety of the exothermic body 10A can be improved.

CONSTITUTION:A fine powder of monodispersion composite oxide is obtd. by hydrosis of alkoxides of structural elements of lead titanate zirconate piezoelectric porcelain except lead, to which a lead oxide powder is added and mixed. The mixture is then heat treated at <=650 deg.C. By this method, lead oxide reacts with uniformly dispersed titanium zirconium multiple oxides so that the reaction proceeds without production of solid solutions of different compsns. Thus, a single-phase lead titanate zirconate solid solution with uniform compsn. can easily be obtd. by heat treatment at 600-650 deg.C which is lower by 100-200 deg.C than a conventional heat treatment.
