Title: Position controller
Inventor: FUTAMI SHIGERU
IPC: G05D3/12
Filed: 1993-01-25
Abstract: PURPOSE:To provide a position controller which can ensure the continuous operating force despite the change of areas by performing the conventional control in a model area and then performing such control as to secure intermediate command corresponding to the transient change degree in a transient change area. CONSTITUTION:Every area is divided into plural model areas having independent characteristics and the transient change areas having the intermediate characteristics. Then, the independent area controllers 1 and 2 are assigned to both types of areas, respectively. An area deciding circuit 5 outputs the degree of decision showing whether the model areas or the transient change areas should be controlled as an area deciding signal according to state value of the command, the operating force, the position, etc. A weight function generator 6 generates the weight gain value alpha according to the area deciding signal. An adder 7 adds together the value obtained by multiplying the output u1 and u3 of both controllers 1 and 2 by the weight gain value alpha and 1-alpha. Thus, a manipulated variable (u) is obtained. A power amplifier 8 controls the position of a mechanism 9 to be controlled by the operating force (f) according to the variable (u). Thus, all areas of both types can be continuously controlled with high accuracy.

Filed: 1983-02-25
Abstract: PURPOSE:To increase internal series resistance on a path, and to improve the effect of current limitation by forming a different conduction type semiconductor region between the shortest distance of adjacent two-terminal protective diodes extending from the same conduction type adjacent semiconductor regions. CONSTITUTION:Two two-terminal protective diodes 3 and 4 are formed on a P well region 7 formed to a semiconductor substrate 8, and terminals 1 and 2 are each led out of contacts 5 and 6 formed to the diodes. In the constitution, internal series resistance is reduced remarkably because the diodes 3 and 4 and other terminals are connected directly through the well region 7. Consequently, a different conduction type semiconductor region of width (l) is formed previously to a notch shape while being positioned between the two diodes 3 and 4 in the well region 7. Accordingly, a current path between the diodes 3 and 4 is by- passed, internal series resistance is increased, and currents are limited effectively to the application of static electricity.

Title: Semiconductor storage device
Inventor: KODAMA HIROAKI
IPC: G11C11/409
Filed: 1994-02-28
Abstract: PURPOSE:To reduce the number of element data busses and to reduce electric power by performing data transfers via sense amplifiers. CONSTITUTION:When data of a low level are inputted to a latch circuit LTC101, the level of a node NDA makes a transition from high to low and the node NDB makes a trasition from a low level to a high level because the low level of the node NDA is inverted in level by an inverter INV 101-Consequently, the state of an NMOS transistor NT102 makes a transition from OFF to ON. Thus, the input side of the inverter INV 101 where the node NDA is connected is pulled in to a grounded level to be held stably at the low level and the node NDB is held at the high level. That is, a data inverse-latching is performed in the circuit LTC101. Further, when data of data busses are in the high level, the inverse-latching operation is not performed and the holding operation of levels prior to the start of writings is performed. In such a manner, the number of element data busses is reduced, operation in a low voltage is made possible and power consumption is reduced.

Title: Data retrieval method
Inventor: MAEDA MASAMI
IPC: G06F3/06
Filed: 1995-02-20
Abstract: PURPOSE: To provide a DKC by which the throughput of a central processing unit(CPU) is prevented from being lowered and signal exchange between the CPU and the DKC is unnecessitated by disconnecting the DKC and the CPU at the time of data retrieval in a computer system provided with a CKD system storage device. CONSTITUTION: At the time of data retrieval, a dummy completion report 61 is performed after the retrieval end of a first record, and a DKC is disconnected from the CPU. By the internal operation of the DKC, data retrieval 63 is executed by data on a cache memory. After the end of data retrieval, a retrieval completion report 64 is performed. Since the DKC and the CPU are disconnected at the time of data retrieval, the CPU is not occupied by the DKC at the time of data retrieval. Besides, since the signal exchange between the CPU and the DKC is unnecessitated, the physical distance between the CPU and the DKC can be extended.

Abstract: PURPOSE:To remove a metal foil evaporated on the surface of a photoresist layer completely by a lift-off method and improve the yield by a method wherein, before a metal pattern is formed on the resist, the resist is applied to the edge part of a semiconductor substrate. CONSTITUTION:Photoresist 5 is applied over the whole surface of a semiconductor substrate 4 by a method such as spin-coating. At that time, the thickness of the photoresist layer 5 is very thin on the edge part B of the semiconductor substrate 4. Therefore, the resist 6 is applied independently to the edge part B only. The resist layer 5 is exposed to an ultraviolet radiation or the like to form a required resist pattern. Then metal such as Pb is evaporated on the photoresist layer 5 formed into the required pattern on the semiconductor substrate 4. Finally, the photoresist layers 5 and 6 are removed by a lift-off method with organic solvent such as acetone to form a metal wiring on the semiconductor substrate 4. As the thickness of the resist layer 6 on the edge part B of the semiconductor substrate 4 is sufficiently large, the metal foil evaporated near the edge part can be removed completely.

Abstract: PROBLEM TO BE SOLVED: To provide a color encoder generating a video signal by which an excellent display image is obtained even when the chrominance subcarrier component of a chrominance signal is resident in a luminance signal. SOLUTION: A demultiplexer 51 generates a luminance signal Y and color difference signals Cr, Cb from a digital signal VD. The signal Y is fed to a terminal 56b of a selection section 56 via delay sections 52, 55 and an elimination filter 54 is used to eliminate the chrominance subcarrier component via the delay section 52 and the result is fed to a terminal 56a. When a detection section 53 detects the chrominance subcarrier component from the signal Y, the signal SD is set to a high level (H). When the signal VD is a signal to generate a composite video signal, the signal CD goes to a high level (H). The signal CY at a gate 58 goes to a high level (H), and the selection section 56 selects the terminal 56a.  The composite video signal CVD is generated by adding the chrominance signal C generated by a modulation section 59 based on the synchronizing signal and the signals Cr, Cb to the signal YDA from which the chrominance subcarrier component is eliminated.
