Patent JP-H1173077-A (JP)
Title: Image forming apparatus
Inventor: KASHIWAKURA KUNIAKI
IPC: G03G21/10
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To prevent a cleaning blade from turning up when an image carrier starts to drive by controlling the rise time drive for the image carrier by a driving means according to the detection result of a detecting means. SOLUTION: A motor drive control part 11 for switching the drive start, the drive stop and the driving speed of a motor 10 performs switching of a driving current or driving voltage input to the motor 10 according to the result of detecting every kind of image forming condition by every kind of detecting means 12. Every kind of detecting means 12 detects at least one of every kind of image forming condition which causes an increase in friction between a cleaning blade 9 and a photoreceptor drum 1. In the case of controlling the drive of the photoreceptor drum 1, the rise time at the time of driving the photoreceptor drum 1 by the motor drive control part 11 is determined according to the detection result of every kind of detecting means 12 in response to a driving signal for the photoreceptor drum 1.  Thus, at the time of starting to drive the image carrier, the friction between the image carrier and the cleaning blade is reduced so as to prevent the cleaning blade from turning up.

Title: Time of flight type mass spectrometry device and convergent lens for ion beam
Inventor: SUGIYAMA NAOKI
IPC: H01J49/10
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To improve robustness to fluctuations of characteristics of an ion source such as mass dependence and plasma state change by sufficiently increasing an opening size in continuous ion flow direction of a pulser ion ejection port than an opening size in continuous ion flow direction of a detector for detecting an ion. SOLUTION: An opening size E in continuous ion flow direction (x direction) of an ion ejection port 22 of a pulser 20 is increased, and a difference in x- direction speed Vx is absorbed by a width in x direction of a packet-shaped ions 24 to be ejected in y direction. If the x-direction speed vx is reduced by a change in characteristics of an ion source with an ion from point B being incident on a detector 30, an ion 24 emitted from a point B will not be incident on a detector 30. Since an ion ejection port 22 is large, an ion emitted from a point C is incident on the detector 39, and sensitivity is kept unchanged. With respect to mass dependence generated for every ion mass, since efficiency of the ion incident on the detector 30 is not changed, the efficiency can be significantly improved.

Title: Image forming device provided with cleaning mechanism
Inventor: KERA HIROSHI
IPC: G03G15/08
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To increase efficiency in carrying, at the time of carrying residual toner recovered from a latent image carrier and to prevent the roughening of toner grains by allowing a sheet-like elastic member to contact with a carrying element in an axial direction. SOLUTION: The residual toner recovered from the latent image carrier by a blade 50 is carried to an end part by the rotation of a carrying screw 52. A rubber sheet 60 is installed between the carrying screw 52 and the frame 49 of a cleaning device. In such a case, the top end of the rubber sheet 60 is fixed on the frame, without fixing the bottom end and a part except a middle part comes into contact with the side opposite to the latent image carrier of the carrying screw 52. Moreover, the length in the axial direction of the rubber sheet 60 is nearly equal to that of the carrying screw 52. Thus, the rubber sheet 60 is installed so that toner retaining between the carrying screw 52 and the frame 49 is reduced to eliminate the generation of rough toner caused by the fixation of the toner between the carrying screw 52 and the frame 49.

SOLUTION: A linked document translation control means 21 reads an original text file to the end of the sentence or a sentence end tag and when there is no translated sentence file in a bilingual translation DB, the means 21 translates an original text and sets the original text, the translated text and the retrieving time of the original text file as one record to the DB by the unit of the sentence. When there is translated text file in the DB, the time field of the record in the DB is set (updated) to the time of the original text. These times are compared with each other to delete a record, where the time stored in the time field is older than the time of the original text file among the records in the DB. When part of the original text is changed in this way, a result translated before is used concerning sentences which were not changed.
