IPC: H01L23/44
Filed: 1985-07-15
Abstract: PURPOSE:To enable such low-temperature cooled type elements as an HEMT to be mounted to a computer by a method wherein the titled device is made in such a constituting that the element fixing beds, that is, the low-temperature cooled type elements to be mounted thereon can be kept in a low-temperature state for a long time without feeding coolant anew. CONSTITUTION:Nitrogen gas under the prescribed pressure is flowed in a first coolant container 1 and liquid nitrogen 4 in the container 1 is fed in a second coolant container 7. At this time, while temperature sensors 2 and 6 indicate a temperature in the vicinity of 80 deg.K, the liquid nitrogen 4 is passing through element fixing beds 5a and 5b and elements 11a and 11b are being cooled. Then, at a point that the temperature sensor 2 indicates a temperature higher than above-mentioned, the state that the liquid nitrogen 4 in the first coolant container 1 has become emptied is shown. At this point, a gas-introducing valve 9 and a leak valve 12 are shut, and a leak valve 12 is opened to flow nitrogen gas under the prescribed pressure in the second coolant container 7 from a gas-introducing valve 10. This causes the liquid nitrogen 4 staying in the container 7 to be fed back into the first coolant container 1. This coolant-moving operation is automatically repeated on the basis of the indicated temperature of the temperature sensors 2 and 6.

Filed: 1990-06-14
Abstract: PURPOSE:To prevent accidents which would be caused by the delay of a motor by letting this apparatus have a first up-and-down movement device for a component holding device and a second up-and-down movement device which is so set as to move the component holding device upward a little later than the first up-and-down device. CONSTITUTION:When it is feared that a rotary disk 10 starts rotating before a suction head 12 rises to the specified height due to the delay of a servo motor 71, a cam system 64 lifts up the suction head 12 forcibly when the rise timing of the suction head 12 by the servo motor 71 is delayed. In effect, the cam system is so set that the timing of the down movement is a little earlier than that of the servo motor 71 and the timing of the up movement is a little later. In the abnormal conditions, the suction head 12 is moved up by the cam system 64. By a cam 64A, an operation lever 64B, a rod end 65A and an up-and-down movement lever for the suction head 65 are moved up. Then, a rod end 65B and an up-and-down movement bar 75 for the suction head are also moved up. Therefore, the suction head 12 is moved up to the specified height before the next rotation of the rotary disk 10.

Title: Loop filter
Inventor: IWASAKI JUN
IPC: H04L27/227
Filed: 1990-06-13
Abstract: PURPOSE:To avoid out-of-lock effectively in a short time with less switching number of times and to bring the state to a stable state by selecting an attenuation factor zeta to a larger value and selecting a loop gain to a smaller value. CONSTITUTION:While a loop filter circuit 14 keeps its gain to be a constant value, an attenuation factor zeta is selected to a larger value and then selects the attenuation factor zeta and the gain to final object values when a control signal Sc1 is outputted from a control circuit 36 succeedingly. Thus, the entire loop gain is selected small by the 2-stages of switching. Thus, when the attenuation factor zeta is increased by selecting an input resistor R1 and a feedback resistor R2, overshoot of response is reduced. Even when the attenuation factor zetais selected large to bring the characteristic of the loop filter circuit 14 close to the characteristic of a linear filter circuit by keeping the loop gain constant, out of locking is effectively avoided and the state is reached to a stable state in a short time.

Abstract: PROBLEM TO BE SOLVED: To stably operate a system using a CPU required for an acknowledge signal without causing hang-up of the CPU even at the time of occurrence of abnormality in the system by using an acknowledge signal detecting means for detecting the acknowledge signal to the CPU. SOLUTION: Since when the acknowledge signal is not outputted to the CPU due to, for instance, occurrence of abnormality in some other device, etc., the acknowledge signal to the CPU is not detected by an acknowledge signal detecting means 5 during a period between the present refreshing and the next refreshing, the acknowledge signal is forcibly generated by an acknowledge signal generating means 4. Thus, even at the time of occurrence of abnormality in the system, the system can stably be operated without causing hang-up of the CPU by the acknowledge signal generating means 4 and the acknowledge signal detecting means 5.

Title: Controller for power converter
Inventor: TSUTSUI YOSHIO
IPC: H02P7/292
Filed: 1982-09-10
Abstract: PURPOSE:To reduce equivalent disturbing current generated under phase control, to moderate reactive power, and to improve the power factor of a power converter by connecting a harmonic filter during initial converter phase control, and controlling the phase of the next converter before the phase control of the converter initially controlled in phase is finished. CONSTITUTION:In order to control a converter Br1, a current command PA is applied to a phase shifter A1. The shifter A1 produces an output alpha1, a converter Br1 is phase-controlled, and controlled at constant current so that the DC current Id becomes constant. This converter Br1 is connected to a harmonic filter PFC during the phase control. The DC voltage Ed is slightly raised by connecting the harmonic filter, but the DC current Id does not vary by the operation of the constant current control, and equivalent disturbing current is slightly reduced. In this manner, the converters Br1, Br2 are simultaneously phase-controlled particularly during the period of converter phase control without deteriorating the constant current controlling performance for an electric motor vehicle or the like, thereby reducing the equivalent disturbing currnt generated during the period.
