Abstract: PURPOSE:To carry out heating to a prescribed temperature stably by putting a magnetic material in the way of enabling the material to be inserted onto the inside of a spiral coil between a high frequency induction coil and a high frequency electric power source and adjusting the self-inductance of the high frequency induction coil corresponding to the alteration of the load of a metal band during heating. CONSTITUTION:A spiral coil 21 is put in the middle of a circular part 20 of a high frequency induction coil 16 and an electric power source connection part and a ferrite 22 is so set as to be detached freely and able to be controlled its insertion level. According to the alteration of load R of a metal band 11 during heating, the ferrite 22 is inserted into the inside of the spiral coil 21 properly by operation of an air cylinder 23 to alter the permeability and adjust the self-inductance L of the high frequency induction coil 16.

Title: Digital modulator
Inventor: NAKAMURA SHIGEKI
IPC: H04L27/20
Filed: 1985-10-11
Abstract: PURPOSE:To apply phase modulation in accordance with a high-speed bit rate in simple constitution by retrieving the selection between an input data pattern and a sampling point in the form of the address information and obtaining the contents of the only memory element as the discrete value of a modulated wave. CONSTITUTION:The input data is converted into an n-bit parallel data pattern by an n-stage shift register 11. Then an access is given to the data pattern contents by the quantized discrete value data that can perform both the filtering for waveform shaping and the modulation of carrier at a time. The contents of the ROM store the discrete value divided in accordance with the sampling points in a single piece of data. Then the outputs of the ROM are defined as time series R1-R8. These discrete values are selected by a counter 14 in accordance with the time base. The above-mentioned actions are carried out alternately between P and Q channels and the obtained P and Q discrete values are transmitted through a D/A converter 16. In such a way, a desired modulated wave is obtained.

Abstract: PURPOSE:To make sheets of succeeding paper stackable without disarranging the already stacked sheets of paper, by installing a paper keeper operating so as to pressing force at a time when the paper hits a contact plate. CONSTITUTION:When a front end of paper 20a passes through both upper and lower surfaces of discharge roller 10, a push roller 11 goes up, and simultaneously with this movements, a tip of a paper keeper 12 goes down with operation of a solenoid 19 and presses an end of one side of the paper groups 20 so far stacked from the upside. And, when a rear end of the paper 20a passes through the discharge roller 10 and is discharged onto an intermediate tray 9, the push roller 11 goes down, contacting the paper 20a, and it operates so as to feed the paper 20a frontward. Simultaneously with a descent of the push roller 11, the tip of the paper keeper 12 turns upward by operation of a solenoid 19 so as not to prevent forward movement of the paper. Therefore, the paper hits a contact plate 13 and is stacked. Likewise, when the succeeding paper has arrived and passes through space between upper and lower parts of the discharge roller 10, the same operation is repeated, thus the paper is stacked on the intermediate tray 9 over and over again.
