Title: Feedback control amplifying circuit
Inventor: SHIMADA TOSHIRO
IPC: H02P6/28
Filed: 1988-10-03
Abstract: PURPOSE:To reduce the number of elements of a circuit and to reduce power consumption and the total offset of an amplifier by converting the output current from the amplifier to a voltage with a resistance, impressing this voltage to the base of a transistor TR and obtaining a feedback control output from the collector of the TR. CONSTITUTION:When a control voltage VIN higher than a reference voltage VREF inputted to an inverting terminal 22 is inputted to a non-inverting terminal 21, an output current corresponding to the product between the input difference between both voltages and a mutual conductance gm is obtained from an amplifier 28. This output current is converted to a voltage VB by a diode D1 and a resistance 25. Since it is impressed to the base of a TR TR7, the TR TR7 is turned on. A motor current ICC is converted to a voltage by a resistance 10 connected to a feedback terminal 9, and this voltage is impressed to a feedback signal input terminal 27 as a feedback voltage VNP. Consequently, the number of elements is reduced and the total offset is reduced because the amplifier has the one-stage constitution.

Filed: 1991-09-27
Abstract: PURPOSE:To obtain the title apparatus and method whereby a stable operation similar to a normal operation can be continued without lowering a pressure in a lower column, even if the amount of its operation is decreased. CONSTITUTION:A regulating valve 30 for regulating a nitrogen gas-charging pressure is provided on a charging pipe 9 for charging nitrogen gas at the top of a lower column 4 into a main condensation-evaporation device 16. When the amount of operation is decreased, the nitrogen gas pressure charged into the main condensation-evaporation device 16 is regulated by a regulating valve 30 and is at a pressure corresponding to the state of decreased operation. In this way, the amount of liquefied nitrogen gas is controlled and the pressure in the lower column 4 can be maintained in the same manner as that of a normal operation.

Abstract: PURPOSE:To efficiently unload cargo without spilling by driving a vertical frame supporting therein a double belt conveyer, into a turnable frame and a nonturnable frame so as to make the direction of the bulk cargo intake port of the double belt conveyer freely selectable. CONSTITUTION:A double belt conveyer 7 and a paddle 8 are driven so that bulk cargo 3 is scooped up by the paddle 8 and is charged into a horizontal receiving section 20. Then, the bulk cargo 3 is conveyed upward by the double belt conveyer 7 on running. In this phase, a lower section frame 14 is turned about a vertical axis by a frame turn device 18. Accordingly, the double belt conveyer 7 is twisted smoothly on the carrier side since a lug retainer roller turnable bracket is turned being guided by a turn rail around a lug retainer roller stationary bracket, and therefore cargo may be conveyed with no spilling. With this arrangement, since the bulk cargo intake port of the double belt conveyer 7 may be changed, thereby it is possible to efficiently, unload bulk cargo.

Title: Optical recording disk
Inventor: DOI HIDEKI
IPC: G11B7/24097
Filed: 1990-09-19
Abstract: PURPOSE:To resolve the disturbance of a control signal to prevent the trouble of recording and reproducing by controlling relations among the diameter and the arrangement of a light beam for tile servo and sizes of a high-reflectivity area and a recording/reproducing area formed on its inside as prescribed. CONSTITUTION:A radius Ruo from the disk center to the outermost periphery of a recording and reproducing area 13 is shorter than a radius Rmo from the disk center to the outermost periphery of a high-reflectivity area 12. Relations Ruo+a<Rmo and a<2d are satisfied where (a) is the diameter of a light beam 7 for tilt servo and (d) is the distance in the disk radial direction between centers of the light beam 7 and a main beam 5. Thus, the light beam 7 for tile servo exists in the high-reflectivity area 12 or is only slightly projected to an outer low-reflectivity area 15 even if the main beam 5 is placed on an outermost recording track 23 of the recording and reproducing area 13, and therefore, the detection signal is scarcely disturbed by the low-reflectivity area 15. Thus, the disturbance of the detection signal is resolved to perform satisfactory system control.

Filed: 1988-10-04
Abstract: PURPOSE:To obtain a transistor with a high switching speed and a high withstand voltage by providing a base contact region, with impurity concentration higher than that of a base region, in the contact part between the base region and the base electrode and thereunder. CONSTITUTION:On the upper surface of a collector region 1, there is formed a base region 3 having a conduction type opposite to that of the region 1. Then, a base contact region 11, with high impurity concentration, deeper than the region 3 is selectively formed in this region 3. A guard ring region is also formed in this process. A base electrode 6 is formed on the region 11. The resistance of the region 3 is expressed by combined resistance of the A region in the region 11 and the B region in the region 3, and the resistance value of the A region is low because the impurity concentration is high therein, so that the resistance value of the region 3 is also low. Accordingly, the carrier 10 under the emitter region 5 can be extracted rapidly during the switching off time, so that the switching time can be shortened.
