Patent JP-H04145842-A (JP)
Title: Constant-current charging circuit for battery
Inventor: TSUCHIYA SATORU
IPC: H02J7/10
Filed: 1990-10-04
Abstract: PURPOSE:To eliminate the need of a current limiting resistance having an excessive allowable power value from the title circuit so as to make the constitution of the circuit simpler by supplying an electric current to a battery by means of a current supplying means through the second switching element. CONSTITUTION:When a charging signal is raised to a high level by means of a command from a CPU, etc., transistors Tr10 and Tr20 are turned on. When the transistor Tr20 is turned on, a charging current ICHARGE starts to flow between the collector and emitter of a transistor Tr30, since a voltage difference is produced between the collector voltage of the transistor Tr20 and the positive pole of a battery. When the electric current flows through a resistance R50, a voltage VR50 is generated and, when the voltage VR50 exceeds the saturated voltage VBE40sat across the base and emitter of a transistor Tr40, the transistor Tr40 is turned on. The value of the resistance R50 is set so that the transistor Tr40 can be turned on when an electric current larger than the necessary charging current ICHARGE flows through the resistance R50.

Abstract: PURPOSE:To manufacture a piezoelectric actuator element characterized by excellent productivity, economy and reliability, by providing electrical connection with inner electrode layers through slit groups. CONSTITUTION:A specified number of conductive tapes 2 are laminated on one or both surfaces of a thin plate 11 of piezoelectric ceramics. The device is baked, and the laminated body of the piezoelectric ceramics, in which inner electrode layers 12 are embedded, is formed. An insulating layer is formed on the end surface of the laminated body, where the inner electrode layer is exposed. A plurality of slits are formed on insulating layers 13A and 13B so that the slits are brought into contact with the inner electrodes 12 at every other layer. Thus slit groups 14A and 14B are formed. Outer electrodes 15A and 15B are formed so that they are electrically connected to the inner electrode layers 12 through the slit groups 14A and 14B. Thus the formation of the inner electrode layers and the junction of the piezoelectric ceramics by way of the conductive tapes are performed at the same time.

Filed: 1988-10-20
Abstract: PURPOSE:To detect a projection of a magnetic disk without brining the magnetic disk and a core into contact with each other by varying a voltage applied between a magnetic head and the magnetic disk, and varying a distance of an electrostatic breakdown generated between the core and the magnetic disk. CONSTITUTION:A magnetic head 1 is provided with a core 2 which can apply a voltage, and to this core 2, a voltage of prescribed magnitude is applied from a power source unit. A magnetic disk 4 is loaded on a disk clamp device and fixed, and rotates as one body by a rotation of said device. As a result, the magnetic head 1 floats up and the magnetic disk 4 and the core 2 are separated by a distance (d). On the magnetic disk 4, a projection is provided. Since the projection is provided, a distance between the magnetic disk 4 and the core 2 becomes smaller than the floating distance (d) in the part in which its projection is provided, therefore, an electrostatic breakdown is generated between the magnetic disk 4 and the core 2. With respect to this electrostatic breakdown, the projection of the magnetic disk 4 is detected by measuring the potential of the core 2 by a potential measuring instrument.
