IPC: B65H23/18
Filed: 1978-10-03
Abstract: PURPOSE: To keep constant for the tape tensile tension during full tape running time, by controlling the winding torque through the detection of tape winding diameter.  
     CONSTITUTION: The number of pulses is detected by the Hall IC3 during a given time to measure the tape winding diameter, the supply voltage to the motor 4 is changed depending on the output of winding diameter detection to control the winding torque. The pulse from the Hall IC3 is compared with the reference counts N 1 ,N 2 ... from the comparison circuit 16 via the count circuit 12 and memory circuit 15, and the result of comparison is fed to the motor drive circuit 17 with two output lines O 1  and O 2 . At the start of tape, since the outputs O 1  and O 2  are both at H, the transistors Q 3  and Q 4  are conductive to minimize the applied voltage to motor. At the end of tape, the outputs O 1  and O 2  are both at L, the transistors Q 3 ,Q 4  are non-conductive, the voltage applied to the motor is increased to obtain a strong torque. Thus, tape tensile tension can be kept constant.

Title: Packet deleting system
Inventor: HATANO TAKASHI
IPC: H04L5/22
Filed: 1988-05-19
Abstract: PURPOSE:To decrease the over load of a packet multiplexing circuit and to decrease the number of wasted packets by wasting an ineffective packet, which arrives before the wasted packet is sent again, without receiving the ineffective packet in a memory in a receiving part. CONSTITUTION:A receiving part 200 wastes a packet I, which arrives from a receiving line 2 with continuing to the wasted packet I until a receiving number comparing means 202 detects coincidence between a transmitting order number NS, which is accumulated in a wasting number accumulating means 201, and a transmitting order number NS to be included in the respective packets I, which continuously arrive. Since the packet to include the transmitting order number NS, which continues to the wasted packet I, is sent again together with the packet to be wasted later, such a packet is the ineffective packet, for which it is not necessary to store in the memory and to send to a transmitting line 3. Accordingly, the receiving part 200 does not store the ineffective packet, which arrives before the wasted packet is sent again, but wastes the ineffective packet. Thus, the over load of the packet multiplexing circuit is reduced and the number of the wasted packets is also decreased.

Title: High breakdown strength semiconductor device and its manufacture
Inventor: OBA MASATAKA
IPC: H01L29/74
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve the breakdown strength of insulation and enable the manufacture of a higher breakdown strength of semiconductor device by applying silicon resin on a field ring. SOLUTION: Silicon 65 is applied on the field ring of an element isolating band 62. By such a constitution, when forward rated voltage 67 is applied between, for example, the cathode electrode 64 and the A node electrode 66 of the reverse conducting Si thyristor being a high-voltage semiconductor device, voltage is generated between the element isolating band 62 and the anode electrode 66. Thereupon, the voltage is applied to silicon resin 65, and dielectric polarization occurs in its inside. As a result, it follows that this has a potential difference as a whole, when observed from outside. Here, the application voltage is removed, as for the dielectric polarization within the silicon resin 65, the charges of + - draw each other, and are neutralized, and the potential difference vanishes.  This way, it returns to utterly initial condition, and the silicon resin 65 can have essential insulating properties.
