IPC: G01R29/12
Filed: 1981-07-20
Abstract: PURPOSE:To simplify the constitution of a vibration part, and also to improve its response property, by controlling the quantity of charge induced in an electrode by a rotation of a shutter, and varying a gate electric field of a field effect transistor. CONSTITUTION:When an object to be measured 9 is charged with electric charge 8, a counter electrode 2 whose pole opposes to this electric charge 8 is charged with electric charge opposite in polarity, through an opening 5 of a case 6. In this case, to a field effect transistor 1, a drain current corresponding to the magnitude of an electric field of the gate proportional to the quantity of electric charge flows. Subsequently, when the opening part 5 is covered with a shutter 3 driven by a driving motor 4, no electric charge is induced in the counter electrode since the shutter 3 is grounded, and to the field effect transistor 1, a drain current in a state that there is no electric field flows. A difference between both of them is fetched as a detecting signal. In this way, the constitution is simplified, and also its response property can be improved by increasing the rotational frequency of the motor 4.

IPC: H02P23/16
Filed: 1986-05-19
Abstract: PURPOSE:To reduce the base rotating speed to an arbitrary rotating speed so that the constant output region can be extended, by controlling the torque partial current command according to a predetermined pattern. CONSTITUTION:In vector control the error between the speed command signal omegar* and the speed detection signal omegar is amplified by a PI control circuit 11 and restricted by a limiter circuit 12 to a certain extent, making the torque partial current command i*q. The pattern of the limiter circuit 12 sets the saturated value of the torque partial current command a definite value to the specified rotating speed lower than the base rotating speed, decreases from the specified rotating speed to the base rotating speed in proportion to the rotating speed, and sets it again constant in higher than the base rotating speed. As a result, the base rotating speed can be reduced to any rotating speed and the constant output region can be extended without modifying the winding specification, etc. of a motor and in machine tools and the like the gearbox mechanism such as a gear, belt, etc., of a heavy cutting machine in a low speed is dispensed with.

Abstract: PURPOSE:To peel label from a peel mount by providing a motor run based on information from a sensor to detect a label peeled from the peel mount and a roller for a feed to pull the one end of the peel mount. CONSTITUTION:A label continuous substance 46 held to holding members 18a and 18b is fed from a roller 24 to a shaft 26 for folding, and folded to peel a label 50 from a peel mount 48.

Abstract: PURPOSE:To enable it to ease the impact of a water hammer being produced at the time of operating a pump and opening or closing an on-off valve by constituting a part of a pipeline with an elastic body being free of expansion or contraction over the whole circumference of the pipeline and in the radial direction of the pipeline. CONSTITUTION:This water hammer lightening device I consists of a pipeline 3 and a toroidal body 4 externally fitting a part of this pipeline 3. Plural interconnecting holes 5 interconnecting the inside and outside of the pipeline 3 over the whole circumference of a part surrounded by this toroidal body 4 are formed in this pipeline 3 at regular intervals, while there is provided a rubber membrane 6 or an elastic body so as to surround an outer circumferential surface of the pipeline 3 at that part. In the case where a sudden pressure change has occurred as a fluid flowing toward a valve from a pump in the pipeline 3 with the closure of an on-off valve (unillustrated herein) in a pipeline 2 is reversely returning to the pump from the valve, the rubber membrane 6 is expanded in the radial direction, thereby relieving a pressure wave, thus any possible propagation of this sudden pressure wave is prevented from occurring.

Title: Character pattern and printing apparatus using the same
Inventor: SHIGEE NOBUYUKI
IPC: G06K15/02
Filed: 1983-06-27
Abstract: PURPOSE:To make it possible to store a large amount of character patterns, by repeatedly reading in a soft mode and printing the dots of an extended part stored in the space region part of the character pattern corresponding to set character intervals. CONSTITUTION:A mapping processor 43 reads a character intervals S stored in page buffer 41 and reads dot patterns corresponding to an arbitrary one line from a first - a N-th lines in a space region to transfer the same to buffer 45 while printing corresponding to one line is performed by a recording head 14 to repeat printing while reducing only one from S. When S=0, (i) is set to 1 and the dot pattern of a first line is read to perform printing corresponding to one line by the buffer 45 and the head 14. In the next step, when 1 is added to (i) and printing is performed in M-times of recirculations, printing corresponding to one line is finished. By this method, a pattern to be continued can be printed in a perfectly continuous state and necessary memory capacity can be reduced and, if it is of the same capacity, a large amount of character patterns can be stored.
