Abstract: PROBLEM TO BE SOLVED: To accurately insure an input voltage margin for an input buffer of a chip having original function, by arranging a buffer element for test and a switch element on a grid line of a semiconductor wafer on which a plurality of chips are arranged. SOLUTION: A test buffer element 23 is arranged on a grid line. A pad of an adjacent chip 31 is used as an output pad of the buffer element 23. Thereby increase of chip area can be restrained. By arranging a switch element on the grid line, the switching of a regular device and the test buffer is enabled. It is also possible to measure the output of an input buffer element of a circuit having an original function by using the same or an equivalent circuit, without being affected by influence of noise at the time of propagation or the like. Input voltage margin of the input buffer of a chip having intrinsic functions can be accurately insured.

Title: Film separation device
Inventor: KITAJIMA AKIRA
IPC: B65H41/00
Filed: 1990-10-26
Abstract: PURPOSE:To prevent damage to the side edge or the like of a substrate, even if the thickness of the substrate fluctuates over a considerable range by forming a certain gap between a guide roller at one side and a guide roller at the other side in the condition wherein a press roller at one side and a press roller at the other side are kept in contact with each other. CONSTITUTION:A substrate when relatively thick, is caused to enter a gap between a guide roller at one side and a guide roller at the other side. As a result, a sub-support frame body 78 is shifted in the thickness-wise direction of the substrate to a certain extent, relative to a main support frame body 60. Press rollers 92, 94, 96 and 98 at one side are thereby separated from press rollers 116, 118, 120 and 122 at the other side to a certain extent. Even the relatively thick substrate, therefore, can be caused to enter space between the press rollers 92, 94, 96 and 98 and the press rollers 116, 118, 120 and 122 at the other side well smoothly.

Title: Image reproducing device
Inventor: YAMAMOTO TATSUYA
IPC: G03G15/36
Filed: 1985-12-20
Abstract: PURPOSE:To copy to the copying paper of the same size by controlling a rotating means and a magnification varying means according to the output signal of a detecting means. CONSTITUTION:When a person who performs retrieval presses a copy button so as to copy a desired image, a line sensor 30 moves on the desired image frame in parallel to a film surface. At this time, the peripheral part of a microfilm F other than image frames is a film dark part, where light is not transmitted; and only light transmitted through the image frames illuminates the line sensor 30, so that the size and longitudinal/lateral direction of the image frame are detected from the range in which the line sensor 30 detects the light. Namely, the length of the breadthwise side of the image frame is detected from the lengthwise width of the line sensor 30, and the length of the film-directional side is detected from the time that the line sensor 30 requires to move on the film surface in parallel, thereby deciding the size and longitudinal/lateral direction of the image frame.

Title: Disk drive device
Inventor: TANAKA TSUTOMU
IPC: G11B19/12
Filed: 1989-11-06
Abstract: PURPOSE:To reduce the size and the weight of a disk drive device with no deterioration of the reliability by identifying a magnetic disk cartridge FD and deciding the loading or the non-loading of the disk cartridge FD with use of a deciding means via plural identifying means. CONSTITUTION:A sensor controller is provided with a sensor part 161 to detect the states of the write protectors 81, 381 and 481 set at the common position to the floppy disks 1, 301 and 401 respectively. Then the sensor parts 162 and 163 are provided at the positions corresponding to an identification port 491 of a floppy disk 401 of 2MB and an identification port 91 of the disk 1 of 4MB respectively. These parts 161 - 163 send out the H signals when the identification ports are detected and then the L signals when no identification port is detected. Thus plural deciding means combines the levels of the signals to identify the FDs and to decide whether the FDs are loaded or not. As a result, the number of FDs to be identified by a single sensor part are decreased. Then a head is separated from the disk when a drop-out state is detected. Thus the scratches are minimized on the disk surface and furthermore a compact and light-weight disk drive device is obtained.

Filed: 1987-11-13
Abstract: PURPOSE:To reduce the detection error rate of reproduced data pulses without troublesome adjustment by discriminating data of a data reproducing signal when the level of the output signal of a low band cut-off circuit is higher than a bias potential. CONSTITUTION:A low band cut-off circuit 3 is provided which cuts off the DC component of a reproduced signal 6 with a time constant, which is sufficiently wider than the longest interval of bits recorded on an optical disk and is sufficiently shorter than the variance period of the envelope of the reproduced signal 6, and couples it to an arbitrary bias potential (for example, GND potential) with respect to AC. Consequently, drop-in of a waveform which does not correspond to actual data is prevented, and drop-out of actual data is prevented. Thus, the detection error rate of reproduced data pulses is reduced without troublesome adjustment.
