Title: Rolling mill for strip
Inventor: UEHORI YUUJI
IPC: B21B13/00
Filed: 1979-10-22
Abstract: PURPOSE:To reduce the rolling load, and to make the high draft rolling work possible, by shifting the center of the inner work roll in the direction opposite to the tension acting on the material passing the rolling pass, and by additionally arranging the roll bender. CONSTITUTION:The center A of the inner work roll 6 is shifted to the run-out side in respect of the center line of the outer work rolls 8, 9, and the center B of the inner work roll 7 is shifted to the feed-in side. Hereby, the centers A, B, of the inner work rolls 6, 7, are shifted to the opposite side of the tensions T1, T2, acting on the material S. When the material S is rolled between the rolls, the feed-in side inner work roll 6 is attracted to the feed-in side, and the run-out side inner work roll 7 is attracted to the run-out side, because of this offset of the work rolls' centers, and the outer work rolls 8, 9, are also held horizontally through the material S; hereby, the roll does not cause the horizontal distortion during the rolling work. Moreover, the roll benders 19, 20, 21, 22, are installed between the roll chocks 15, 16, of the outer work rolls 8, 9, and the housing 12, and hereby, the better effect can be attained.

IPC: H03M1/10
Filed: 1987-05-29
Abstract: PURPOSE:To adjust the MSB of a converter with a high accuracy without needing an accuracy for a measuring instrument by minimizing the input level of the conveter, preventing a high order bit excluding a maximum bit MSB from being operated and shifting the low order bit to operate, to the high order bit. CONSTITUTION:An oscillator 1 is inputted to an A/D converter 2, the bit of a high order bit '0' or below excluding the MSB of respective bit outputs of an output 0, here, a 12th bit to a 16th bit (LSB) are connected from the high order bit of, a D/A converter 4 up to a 6th bit, and the input up to the LSD less than a low order 7 bit is not executed, and on the other hand, while the D/A converting output is monitored by a distortion factor meter 5, a vari able resistor for fine adjustment of the current source of the MSB of the A/D converter is adjusted, and adjusted so that the distortion can be minimum. In this case, the output level of a D/A converter comes to be a large level only by the shifted part, the accuracy of the D/A converter rises for that part, and on the other hand, the S/N of a measuring system is improved. Only for the part to input the level small, the adjustment of the MSB is executed without needing the accurary of the oscillator and the distortion factor meter.

IPC: H02J3/12
Filed: 1994-06-17
Abstract: PURPOSE:To compensate voltage variation instantaneously and continuously by connecting a voltage detecting circuit which detects the load-side voltage of a line to a voltage adjusting circuit and stabilizing the load-side voltage of the line on the basis of the detected voltage from the voltage detector. CONSTITUTION:A transformer 30 for adjustment 30 boosts a voltage in expectation of a voltage drop due to a load current and the voltage adjusting circuit 50 places in a series transformer 40 in operation according to the load-side detected voltage of the line obtained by the voltage detector 70. The capacity of the voltage adjusting circuit 50 is reduced through the voltage boosting operation of the transformer 30 for adjustment, and consequently heat loss due to the heat generation of a thyristor constituting the main circuit part of the voltage adjusting circuit 50 is reducible, thereby reducing electric power loss. Even if abrupt voltage variation is caused on the line, the series transformer 40 can raise or lower the load-side voltage of the line instantaneously and continuously through the operation of the voltage adjusting circuit 50. Consequently, the voltage variation can be compensated instantaneously and continuously.

Abstract: PURPOSE:To prevent the deterioration of airtightness and sealing intensity by constituting a cap by a main body having a gas releasing aperture and a cover adapted to be attached to the main body so as to close the aperture. CONSTITUTION:A semiconductor chip 1 is united to a base 10 and the main body 14 of a cap is placed on he base 10 to deposit the mainframe by glass 5 after connecting the semiconductor chip 1 to a lead frame. At that time, resin 1a on the chip is heated to emit a large quantity of gas which is diffused to the outside through an aperture 16. Therefore, gas pressure will not be generated in the space 6 and the dimension of a glass layer having sealing width l1, will not be reduced. Therefore, airtightness and sealing intensity will be improved. Then, a cover 15 is brazed 17 on the upper surface of the mainframe and a degassing hole 16 is airtightly sealed. Glazing temperature at that time is for below than the temperature at glass deposition. Therefore, gas emission from the resin on the chip 1 is a very small amount and gas pressure will not exist in the space 6 and the sealing function by the cover 15 will not be lost. In this composition, a high-reliability device housing a resin coated chip in a container will be obtained at low cost.
