Filed: 1993-01-22
Abstract: PURPOSE:To provide a color linear image sensor able to use a simple two-phase drive system as a drive method of a CCD resistor eve if a wiring is provided on a channel stopper. CONSTITUTION:A wiring using a first layer polysilicon film 111-1A is provided on the channel stoppers 106 of the photoelectric conversion arrays 101R,... for being connected to a first transfer gate electrode 111-1 of a CCD resistor so as to perform connection to a second transfer gate electrode 112-2 using a contact hole.

Filed: 1987-01-20
Abstract: PURPOSE:To quickly evaluate a semiconductor memory by executing test patterns corresponding to only the number of points of an output comparison voltage to write information of an output waveform in an internal memory and reading out contents of this memory to trace the output waveform. CONSTITUTION:An optional output signal is outputted from a test memory 7 and is compared with the voltage analogically set to a VO 9 by an ACP 8, and the result is inputted to DCPs 10-13, and it is discriminated whether this result is good or not by an expected value and a strobe time. If the result is good, data '1' is set to respective memory planes. The test of the test device is controlled by test patterns, and the operation executed by one test start is terminated when test patterns are terminated. If data changed at equal intervals from OV to a test voltage is set to a VOM 20 and the operation is repeated (l-number of times) until an ADC 45 reaches a maximum value, data is written in a TRM 40 as shown in a figure (c), and the output waveform shown in a figure (b) is equivalently traced.

Abstract: PURPOSE: To prevent the tape end (EOT) from being removed from a reel in a write and read operation time by not only stopping automatically running of the magnetic tape but also reporting it to upper-level devices on a basis of count information.  
     CONSTITUTION: When an EOT mark is detected to make detection signal 33 high- level, operation circuit 1 is made effective through ROM 3, and the number of allowable information on the magnetic tape following the EOT mark through 32, the number of information converted to an inter-block gap IBG length through 30, or the number of information converted to the prescribed demagnetization running distance for write error is read out and is subtracted from a prescribed number of information, which is set in register 2, for every block unit which should be transferred after EOT mark passage through 10 or the number of information to be skipped to read for read skip through circuit 1; and when the count value of register 2 becomes zero, a signal outputted from register 2 becomes not only a tape running stop signal but also a report signal to upper-level devices. Consequently, EOT can be prevented from being removed from the reel due to overrun of the tape in a write and read operation time including error occurrence.

Title: Shape controlling method
Inventor: OOHIRA ATSUSHI
IPC: B21B37/00
Filed: 1983-01-26
Abstract: PURPOSE:To reduce further the variance of a sheet thickness regulation performed by shifting an intermediate roll shaft and to perform excellent sheet thickness rolling by providing the intermediate rolls having mutually different diameters to a multi-roll mill consisting of backup rolls, intermediate rolls, and work rolls. CONSTITUTION:In a multi-roll rolling, sheet thickness is regulated by shifting intermediate roll shafts. At that time, the sheet thickness difference such as G, H, I, J are produced by the rigidity and the amount of shifting of the intermediate roll. Therefore, an upper intermediate roll 11 whose diameter is made larger than that of a work roll 5 so as to make its rigidity larger than that of the work roll 5, is installed between a backup roll 3 and the work roll 5. A lower intermediate roll 12 is installed, whose diameter is set so as to make its rigidity smaller than that of the roll 11 and larger than that of the roll 5. In this way, equalized sheet thickness rolling is performed by changing a bending restricting zone for the roll 5 to reduce the partial up-and-down variation difference for the prescribed sheet thickness.
