When off-time T passes, the actual thicknees deviation DELTAh and set thickness change alphaDELTAS are compared, and the roll gap is adjusted by a acrew-down cylinder 24. By repeating this operation, the optimum thickness is obtained always while passing. When becoming the stationary high speed rolling state, the gauge control by the control device 16 is released, so that the control device 18 governs the control as in conventional case.

IPC: G02F1/136
Filed: 1995-03-15
Abstract: PURPOSE:To provide a liquid crystal display device which is formed larger in size and higher in fineness without complicating data output circuitry by optimizing and decreasing parasitic capacitance. CONSTITUTION:In the liquid crystal display device, pixel electrodes for display arranged in an matrix form, scanning signal lines 4, data signal lines 5, active elements and driving circuit 2 for data signals are formed on a scanning substrate and a counter electrode 3 is formed on a counter substrate. Plural apertures 11 are formed at the counter electrode 3 in the parts corresponding to the data signal lines 5. And also the liquid crystal display device is formed out of a liquid crystal layer disposed between both substrates and a date signal line driving means for outputting data signals to the data signal lines simultaneously with sample video signals at the prescribed timing within the horizontal scanning period of the video signals to the date signal lines 5. The plural apertures 11 are thus formed at the counter electrode 3 and at least a part thereof are disposed in the parts facing the data signal lines 5 and, therefore, the parasitic capacitance on the data signal lines 5 are decreased and are optimized to meet the data output circuitry since the parasitic capacitance existing between the data signal lines 5 and the counter electrode 3 are small.

Title: Monitoring system of set state of memory cassette
Inventor: HATSUTORI SEIICHI
IPC: G11C5/14
Filed: 1983-03-31
Abstract: PURPOSE:To simplify the circuit constitution by using two signal lines doubling an electric power supply to connect an adaptor to a memory cassette and connecting an electric element which can flow forcibly a set state detecting current between said two lines. CONSTITUTION:A memory cassette 3 is connected to an adaptor 2 to which 50V is applied via two pins of a connector, and a fixed current is flowed to an electric element 3z. This current is set at such a level that can at least actuate a detecting circuit 2h of the cassette 3 which is set. Thus it is possible to detect the level of the voltage set via an amplifier and then a set state. Then a control circuit is actuated after receiving the output signal from the circuit 2h and detecting a complete set state. Thus the storage contents of the cassette 3 are read out or written. In case the cassette 3 is not completely set, the circuit 2h is not actuated since the voltage level set by a setting current cannot be detected. Furthermore the circuit 2h does not reach the set current level when the set state of the cassette 3 is incomplete. Thus the circuit 2h is not actuated.

Title: Power converter
Inventor: YAMASHITA TAKASHI
IPC: H02M7/21
Filed: 1982-04-07
Abstract: PURPOSE:To reduce the loss of a rectifier by detecting the coil voltage of a transistor and driving a circulating switching element. CONSTITUTION:Since a positive voltage is generated at the (.) mark side of the coil n5 of a conversion transformer 4 is generated when a transistor 2 is turned ON, the output of an inverter 12 becomes zero, a rectifying field effect transistor 5 becomes ON, and a circulating field effect transistor 6 becomes OFF. Accordingly, the voltage of the coil n2 of a conversion transistor is transmitted to an output terminal 9. When the transistor 2 becomes OFF, the transistor 5 becomes OFF and the transistor 6 becomes ON. Accordingly, the voltage of the coil n2 of the conversion transistor is blocked, and a current from the smoothing choke coil 7 is circulated. The ON voltages of the transistors 5, 6 are suppressed to low value by the above operation, thereby forming a rectifier having low loss.

Title: System for managing working area of reentrant program
Inventor: FUJIMOTO TAKANOBU
IPC: G06F9/44
Filed: 1983-03-31
Abstract: PURPOSE:To improve the executing performance of management of the working area of a reentrant program, by limiting a supervisor call by GETMAIN/ FREEMAIN to the first reentrant program. CONSTITUTION:When the execution of a reentrant program A is started in the first place, A sufficiently large working pool 7 is secured by a GETMAIN macro. At the time a control table T containing a pointer which manages a working area is implemented. When a call is made from the reentrant program A to, for example, a non-entrant program X or from the program X to an entrant program B, the control table T is handed over. The program X does not use the control table T, since the area managing system is different, and the control table B is handed over to the program B as it is. The program B knows a secured working area pool from the pointer of the control table T and secures its own working area.
