Title: Data processor
Inventor: HAMAMOTO TOSHIMI
IPC: G06F13/00
Filed: 1993-04-27
Abstract: PURPOSE:To decrease the rate of use of a transfer bus by respective CPUs and reduce the bottleneck of the wait for the use of the data transfer bus by providing with a signal line for maintaining data conformity characteristic on a data transfer bus means to connect low speed sharing memory device to high speed memory device. CONSTITUTION:When a 1st CPU 2 writes in a 1st high-speed memory device 3, a miss is caused. The 1st high-speed memory device 3 reads the corresponding latest data out of a 2nd high-speed memory device 5 through the data transfer bus 6. The data are updated immediately in case of read processing right after the write miss of the data is caused, so a signal line 7 for invalidating the data is made active and a request to invalidate the data is sent to the 2nd high-speed memory device 5. The 2nd high-speed memory device 3 sets the valid bit of the sent-out data to 0 to invalidate the data. The 1st CPU 2 writes in the 1st high-speed memory device 3 again and sets a dirty bit to 1 since the data in the 1st high-speed memory device 3 are the latest.

Filed: 1999-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce contamination in a manufacturing line installation and improve quality of a semiconductor device by preventing generation of dust during transportation and loading/unloading and preventing gradation of a resin pellet itself by holding a plurality of resin pellets spaced apart each other and blocked from the air.

Title: Method and device for monitoring passage of mark on web
Inventor: MAATEIN GOO
IPC: B41F33/06
Filed: 1988-04-26
Abstract: PURPOSE: To monitor the web matching by projecting an image of an mark onto a detection station so that two axes may be traverse to the direction of web movement, and by determining the times at which equal areas of a mark are projected on either side of the areas. CONSTITUTION: When a matching mark 13 reaches a detection station 7, an image of the mark is projected onto a quadrant array 20. An output signal P represents the effect of a matching mark image on photo detectors 21 and 22 compared with images on photo detectors 23 and 24. A signal Q passes the intermediate zero position when a mark coincides with the center of an axis 25. A controller 6 measures the times t1 and t2 and computes the time t3 corresponding to the time which a fictitious line 37 is crossed with a matching mark traverse to the web direction 38. The computation is repeated by the controller 6 as per each mark 13-16 and the difference between the times t3 is computed. If there causes a difference, the correction value to minimize the time difference is determined by controlling the web speed. The deviations in the horizontal direction are measured by computing t1 and t2 .
