Title: Printer
Inventor: HASEGAWA MASARU
IPC: B65H5/00
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To eliminate occurrence of a mark in connection with a decrease in a quality of a printed matter due to a gripper mark or the like by effectively releasing a printing sheet from a nip forming member of an impression cylinder or the like without attaching a wave pattern due to an air blowing to a print image and without generating a curling. SOLUTION: A plurality of pattern formed electrodes 9 are provided at an interval in a circumferential direction on a surface of an impression cylinder 6 as a nip forming member. When a voltage is applied to the electrodes 9, a printing sheet is attracted to the surface of the cylinder 6 by an electrostatic force. Only the electrodes 9 approached to a guide plate 10 are sequentially interrupted at a voltage supply at a delivery side of the cylinder 6. Thus, the electrostatic force is removed or weakened only at the delivery side to easily release a leading end of the sheet.

Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To attain improvement in security by judging whether an IC card is used by an authorized user or not while using a fingerprint pattern. SOLUTION: A memory 11 is provided with a fingerprint pattern storage part 12 as a ROM area for storing the fingerprint pattern of a prescribed finger of the card user.

Title: Semiconductor device
Inventor: BERA BII GAAFUINKURU
IPC: G02F1/35
Filed: 1992-12-24
Abstract: PURPOSE: To modulate optical radiation with the frequency higher than an electron-photon resonance(EPR) frequency by absorbing internal sub-band radiation and changing the free-carrier distribution function in a predetermined region of the semiconductor body. CONSTITUTION: A body 20 has one or more quantum wells(QW) 23. A modulating mechanism changes the free-carrier distribution function in the QW 23. Internal sub-band radiation(ISBR) 28 of a relatively long wavelength is used for changing the transparency of the body 20 for internal-band radiation(IBR) 27 of a relatively short wavelength. A modulating signal is the electric field which is applied on the entire region of the QW 23. The ISBR absorption is tuned by a Stark effect. The IBR 27 is modulated in the short time, and the IBR pulses of the narrow quantity are generated. Thus, the laser output can be effectively modulated for the modulating frequency, which is considerably higher than the EPR frequency.
