Abstract: PURPOSE:To eliminate a welding defect and breaking an electrode wire and to improve the performance of a can making machine by specifying the 0.2% yield strength of copper wires for welding electrode wires which are wound on both upper and lower electrodes in the joining parts of a can formed by rolling to a square shape in section by the can making machine. CONSTITUTION:A can of a relatively small size is made as the joining parts of a  metallic sheet 1 formed to a can shape are welded between the electrode wires 3  which are wound in the hollow grooves of upper, lower electrode wheels 2, 2' in  said joining parts by guiding rolls 6, 6'. The wires 3 consist of round copper wires  4 formed to a square shape in section by upper 1, lower rolls 5, 5'. Back tension is applied upon the wires by said forming, and the wires are wound in arrow directions are taken off by rolls 7, 7'. Here the conductivity of the wires 4 is set at >=100%, the tensile strength at 25-27kg/mm.<2>, the elongation at >=25%, and the 0.2% yield strength at 3.5-16.5kg/mm.<2>. If the 0.2% yield strength is below the lower limit, the deformation during welding of the wires 3 is large and there is an easy tendency toward generation of welding defects and wire disconnections. If said strength is in excess of the upper limit, the formability to a ssquare shape in section is degraded and good welding is degraded and good welding is no larger accomplished.

Filed: 1990-06-20
Abstract: PURPOSE:To prevent the occurrence of the flow of an image caused by a developing history occurring on a latent image carrier, to stabilize the carrying quantity of toner, and to reduce density irregularities and base fogging by providing a drum-like thin film member as a developing roller, a driving roller, and a developer supplying/peeling off member peeling off a one component developer which is not used in the last development. CONSTITUTION:The developer supplying/peeling off member 12 has a fur brush for electrifying the toner to a desired polarity according to a triboelectrifying system, and the fur brush is formed by planting fiber on a conductive supporting body freely rotated. A potential difference is given with respect to the developing roller 9 by a voltage applying means 17.

On the other hand, the developer supplying/ peeling off member 12 tentatively peels off all of the toner which is not used for the development, so that the solidifying of the toner on the developing roller and the occurrence of the flaw of the image of the density irregularities, etc., caused by the developing history are suppressed.

Title: Constant current circuit
Inventor: OKASHIN YAMATO
IPC: H03F3/343
Filed: 1988-06-29
Abstract: PURPOSE:To improve a characteristic as a constant current circuit, namely, a stability, a power voltage characteristic, etc., by making a current mirror circuit and a transistor into a prescribed connected relation. CONSTITUTION:A current mirror circuit 1 is composed of transistors Q1 and Q2. Transistors Q3-Q7 are the main circuit of the constant current circuit, and transistors Q8 and Q9 are for fetching constant current outputs. When a power source is inputted, a positive feedback is applied to the current loop of the transistors Q3-Q7, and respective collector currents I3-I7 are increased. At such a time, the collector currents I3 and I4 are linearly increased to a base current Ib. However, since a base bias is executed by the voltage of the sum of the base. emitter voltage of the Q6 and Q5 and the lowering voltage of a resistor R5, the collector current I4 is increased in an exponential function way (through the current I4) to the base current Ib. Since, at the time of I6=I3(=I4), the current (I3-I6) of the difference is made into zero and I7=0 is executed, respective currents are stabilized at the point of I6=I3.

Filed: 1990-06-20
Abstract: PURPOSE:To reflect musical tone control parameters in generated musical tones by sensing the entire stroke of an operating element, retriggerably detecting the acceleration of the operating element and changing and controlling the musical tone control parameters according to the acceleration data. CONSTITUTION:The entire stroke of the movement of a key 1 is sensed by a key guide block 10 and a key guide cap 7. The coil patterns of the respective faces face the respective inside surfaces of the cap 7 when the block 10 is inserted to the cap 7. The opposite areas and spacings are changed by the key operation. Since the cap 7 is made of a metal, the inductances of the coil patterns on the respective surfaces change approximately linearly. The touch output level obtd. from the pattern 12a pairs does not fluctuate any longer with each of the keys. The respective coil patterns 12a to 12c are directly coupled to the oscillation circuit of a printed circuit board 8. The pulses of the oscillator are retriggerably counted in a prescribed time unit by an acceleration detecting means during the key operation and the acceleration is detected. The musical tone parameter is changed according to the acceleration data and the oscillation frequency is changed by a change in the L value of the patterns 12, by which the control of both initial/after touches is executed and the intricate musical tone control is executed.
