Title: Control of converter for obtaining dc from polyphase ac
Inventor: NISHIJIMA TETSUYA
IPC: H02M7/219
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To suppress the distortion factor of AC current so as to be minimum, while ensuring following-up characteristics by obtaining the variation amount of an error vector from a specific expression, and selecting a switching vector whose angle becomes the smallest among selectable vectors as a second vector. SOLUTION: The variation amount β of an error vector can be obtained from an expression, when a selected vector is outputted during one cycle in an instantaneous active and reactive current controller for a voltage-type converter. For the first selection principle in the case of a long vector which converges an error at the highest speed is selected at the time of transient where an initial error is large. On conversely, a short vector which suppresses the generation of ripple so as to be minimum is selected at the stationary time, when the initial error is already entered in a ripple range. In the second selection principle, when the first vector β1 is selected, and if it is switched to the second vector with a prescribed timing, a vector terminal error of which is nearest zero is selected as the second deciding vector β2 .

Title: Amplitude limit circuit
Inventor: MONARI TOSHIHIKO
IPC: H03G11/00
Filed: 1992-07-01
Abstract: PURPOSE:To keep a limiting voltage constant at all times independently of a temperature change by cancelling the temperature characteristic of 1st and 2nd transistors(TRs) whose emitters are connected to a prescribed point by the temperature characteristic of 3rd and 4th TRs. CONSTITUTION:A base voltage of TRs Q1, Q2 to connect to a prescribed point is imparted from a voltage application power supply via TRs Q3, Q4. Thus, the temperature characteristic of the TRs Q1, Q2 is cancelled by that of the TRs Q3, Q4 and a limiting voltage is kept always constant independently of a temperature change. That is, the voltages VL+VBE3 and VH-VBE4 are applied to each base of the TRs Q1, Q2 inserted among circuits X, Y, Z to let the voltages respectively be V1, V2. Even when a current is inputted/ outputted to/from the circuits Y, Z via the TRs Q1, Q2, since the circuits Y, Z are constituted with feedback circuits, the respective voltages at connecting points P2, P3 and the respective emitters of the TRs Q3, Q4 are immediately restored to the original voltage. Thus, the base voltage of the TRs Q1, Q2 are kept always to the voltage V1, V2 respectively.

Title: Semiconductor device and manufacture thereof
Inventor: WATANABE YOSHIHARU
IPC: H01L21/3205
Filed: 1990-07-02
Abstract: PURPOSE:To easily detect an abnormal growth operation, to eliminate a need for a skill and to enhance reliability by a method wherein a monitor used to watch the abnormal growth operation is formed, an element is formed at the same time and the existence of the abnormal growth operation is watched by whether a plurality of buried layers come into contact or not. CONSTITUTION:Buried growth-operation monitors are formed on a diffusion layer 4 not used as an element and on a field insulating film 2. When a gate electrode 3 is formed, a conductive film 8 is formed simultaneously on the field insulating film 2. For example, poly-Si used as its material. Then, tungsten (W) is grown selectively by a CVD method. A buried layer 6 is grown inside a contact hole for element use; buried layers 6a are grown inside contact holes for monitor use on the conductive film 8; and buried layers 6b are grown inside contact holes for monitor used on the diffusion layer 4. In the case of the buried growth-operation monitor formed on the conductive film 8, a resistance value between upper-layer electrodes 9a becomes nearly infinitely great when no abnormal growth operation exists. However, when an abnormal growth operation exists and the buried layers 6a come into contact, they are in a short-circuited state and their resistance value becomes extremely low. Consequently, the abnormal growth operation can be detected.

Abstract: PROBLEM TO BE SOLVED: To prevent the vacuum of a vacuum bath from deteriorating and to enhance reliability by providing a valve for opening and closing an interlocking hole due to external operation at the interlocking hole among a normal temperature damper vacuum bath, a low-temperature damper vacuum bath, and an edge vacuum bath. SOLUTION: Valves 15a and 15b are opened during evacuation, and a normal temperature damper vacuum bath 10, a low-temperature damper vacuum bath 11 and then an edge vacuum bath 12 are interlocked via interlocking holes 13a and 13b. In this state, air is evacuated from an evacuation pipe 14 and the inside of the vacuum baths 10, 11, and 12 is evacuated to a high vacuum. Then, after the evacuation has been completed, the port of the evacuation pipe 14 is sealed and at the same time the valves 15a and 15b are closed, thus closing the interlocking holes 13a and 13b of the vacuum baths 10, 11, and 12 and forming each independent vacuum spaces by the vacuum tanks 10, 11, and 12.  Since the vacuum layers are each independent, deterioration in vacuum occurs only at the edge vacuum bath 12 and vacuum heat insulation can be maintained in the vacuum layers 10 and 11, even in case air leaks from edge shafts 1 and 2.
