Title: Retrieval auxiliary device
Inventor: KAWAMURA TAKAYUKI
IPC: G06F17/30
Filed: 1985-08-21
Abstract: PURPOSE:To execute a high-speed retrieval by providing a comparison means, which compares an item maintained by a retrieval item maintenance means with a specific item stored in a specific item memory means in order of address and regards the address of the specific item as the retrieval start address in a memory device when both items coincide. CONSTITUTION:When a coincidence signal is latched in a flip-flop circuit 22, or a detection signal is latched in a flip-flop circuit 26, the coincidence signal is transmitted to a central processing unit and a counter control circuit 18 through an OR gate circuit 28. Until the interruption occurs after the operation of the retrieval auxiliary device, the central processing unit is not concerned in the retrieval operation, but only monitors the occurrence of the interruption to detect the termination of the retrieval operation, and can execute other tasks, while monitoring the termination of the retrieval operation. When the interruption occurs, the central processing unit commands a register 30 to transfer the maintained count value, receives the count value through a data bus 32, multiplies this count value by 100, and transmits it to the memory as an address. Thereby not only the high speed retrieval can be realized, but also the time occupied by the central processing unit can be reduced.

Abstract: PURPOSE: To cut billets in a high temperature range with a small cutting energy and to automate the next scarfing, by detecting the carrying amounts and locations of surface flaws of red hot ingot being carried, and by accurately deciding locations of surface flaws of ingots after the front and rear ends of ingot are cut off from lengths of unnecessary parts at the front and rear ends of ingots.  
     CONSTITUTION: When a red hot ingot is carried, the carrying amount and surface flaws of the ingot are measured and detected by a carrying amount detector 1 and a surface flaw detector 4 using infrared ray, and locations of surface flaws of the ingot are decided by a judging/operating circuit 40. The data thus operated are stroed in a storage circuit 50. Moreover, detected values of a tail end location detector 5 and a front end location detector 6 for ingots are inputted into a tail end cutting length operating circuit 81 and a front end cutting length operating circuit 82, respectively, and locations of flaws on the surface of the billet after the front and tail ends of the ingot are cut off are accurately decided by a cut shape operating circuit 82. Since the front and tail ends of the ingot are cut off while the ingot is red hot, a cutting energy which is smaller than that required when the ingot is cut under a low temperature is required. After cutting, the ingot is carried to the next surface scarfing process.

Title: Driving device for liquid crystal display element
Inventor: KAMATA KENJI
IPC: G02F1/133
Filed: 1990-07-10
Abstract: PURPOSE:To switch a light scattering state and a light transmitting state speedily and to make an excellent display without any flicker by generating a driving signal of 1st relatively low frequency by removing higher harmonic components from the output signal of a 1st signal generating means which is generated through switching operation. CONSTITUTION:When the liquid crystal display element is placed in the light scattering state, a semiconductor switching element 1 derives a rectangular wave of 1st relatively low frequency to turn off a switch SW1 and turn off switches SW2 and SW3. Consequently, the driving signal generated by removing higher frequency components from the rectangular wave through a low-pass filter 2 is led out to an output terminal OUT. When this driving signal is supplied to the liquid crystal display element, the light transmissivity decreases and the light transmitting state changes into the light scattering state. When the element is put in the light transmitting state, the switching element 1 generates a rectangular wave of 2nd relatively high frequency to turn on the switch SW1 and turn off the switches SW2 and SW3. Consequently, the light transmissivity of the liquid crystal element increases speedily and the element enters the light transmitting state.
