Filed: 1990-11-09
Abstract: PURPOSE:To contrive the simplification of the constitution of a semiconductor manufacturing device by a method wherein the good or bad of a semiconductor chip is decided by an image processing device for defective identification information use on the basis of an image output signal from a TV camera, which images the chip at a stand-by position, and alignment information on the chip is obtained by an image processing device for alignment information use. CONSTITUTION:Before a bump formation treatment is executed, a bonding head 2 is moved to a stand-by position to a semiconductor chip 1 to be treated, is stopped there and the object chip to be treated is imaged by a TV camera 10. An image output signal which is generated from this camera 10 is branched into two and the two branched signals are respectively inputted in an image processing device 23 for defective identification information use and an image processing device 12 for alignment information use. Then, an image output signal 11 is inputted in the device 23, whether there is a defective identification mark 3, which is used as defective identification information, on the object chip to be treated is identified and whether the object chip to be treated is a non-defective or a defective is decided. Thereby, a camera for defective identification mark image pickup use and a lighting device become unnecessary and the constitution of a semiconductor manufacturing device is simplified.

Title: Printing device
Inventor: KATOU KAZUKI
IPC: B41J2/255
Filed: 1991-10-25
Abstract: PURPOSE:To make printing density variable by providing an angle regulating mechanism for regulating an angle of a printing head with respect to the direction in which a sheet is fed, a printing head angle controlling section, and a printing timing controlling section corresponding to the angle of the printing head. CONSTITUTION:A sheet 4 on a platen 3 is pressed to the side of the platen 3 by a printing head 1 so as to be held between the printing head 1 and the platen 3, and is fed in the direction shown by the arrow A. An angle regulating mechanism 6 for regulating an angle of the printing head 1 with respect to the sheet-feeding direction A makes the printing head 1 assume a variable angle alpha of inclination from a position normal to the sheet-feeding direction A. An angle controlling mechanism 7 sets the angle alpha of inclination of the printing head 1 by controlling the angle regulating mechanism 6 and communicates the angle information to a printing timing controlling section 8. This printing timing controlling section 8 detects relative positions among the angle alpha of inclination of the printing head 1, the sheet 4 and the printing head 1, and sends printing data to the printing head 1 to make it perform printing while controlling the printing timing in relation to dot heads 2.

Title: Digital signal processing method
Inventor: HIRAOKA YASUSHI
IPC: H04L27/22
Filed: 1999-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a signal processing method capable of exactly modulating bits by canceling the offset frequency of a detected signal. SOLUTION: After the sampled data of a baseband are made into complex number (separated to I and Q data), the offset frequency contained in these data is estimated. Then, the filter coefficient of a low-pass filter(LPF) is shifted so that this offset frequency can become the center frequency of the filter. Therefore, the LPF becomes a complex filter. Thus, even when the offset frequency is contained in a baseband signal, a frequency spectrum is completely preserved and the interference from adjacent channels can be removed. Further, because of digital processing, the fluctuation of the offset frequency can be followed without delay.

Filed: 1986-12-24
Abstract: PURPOSE:To effectively access a file and at the same time to avoid a deadlock state by locking the information needed for access in the order of high order and carrying out the access action. CONSTITUTION:When /A/C/E/H/ (/: sections, /A/C/E: path up to a directory H to be deleted) is designated, A, C and E are successively searched. In this case, the directory areas 201, 202 and 203 are successively locked and unlocked and the return information includes the position of the area 203 and a fact that the area 203 can be searched. In such a way, only the necessary information is locked to give an access to a file. While the information are locked in the order of high order. Thus plural tasks can give accesses simultaneously to the same file system as long as those information needed for said accesses have no overlap.

In succession, when the transfer distance has differed from the reference value, a control part 10 emits a warning. Thus, elongation of the sheet body S and chromatic aberration in gravure can be detected in a real time manner.
