IPC: G03G21/00
Filed: 1990-09-28
Abstract: PURPOSE:To obtain a clear and improved image without stain caused by toner by thrusting the stagnating toner stuck to the surface of the image carrier from the upper face part at both sides to a center part along the blade edge of both side surface parts. CONSTITUTION:The blade member 12 consists of a plane part 121 and both side surface parts 122, 122 where both the wings are bent and the lower edge surface of the plane part 121 forms a linear edge part 12. Also at the lower edge surface of both side surface parts 122, 122, curved edge parts 12B, 12B are formed and they have a shape abutting on the curves b, b on a circumferential surface of the upper stream side in a revolving direction in the vicinity of both sides of a cylindrical surface of a photosensitive body drum 100. Accordingly a residual toner T peeled with a linear edge part 12A is pushed away and moves to both side parts on the circumferential surface of the photosensitive body 100. But the residual toner T in the vicinity of both sides of the circumferential surface of the photosensitive drum 100 is cought with the curved edge parts 12B at the more upper stream side than the linear edge part 12A and it is pushed away toward the linear edge part 12A along the curved face. Hence the dropping and the scattering of the residual toner are prevented.

Title: Time synchronization of packet radio signal with base station
Inventor: SAWYER ALBERT JOSEPH
IPC: H04W92/14
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To stabilize synchronization by adjusting a specific transmission time indication value and the transmission time from a packet source to an offset and sending following packets by a radio transmitter part at desired arrival time when the following packets are enabled to be received. SOLUTION: A mobile body exchange MSC:1 sends a packet containing several order numbers to a base station 3, which receives the packet and calculates its arrival time in terms of code division multiplex system CDMA system time. So that packets are transmitted at a CDMA system time for the transmission of the packet having the received order number, the time when the packet having the order number is received is subtracted. The base station 3 sends the offset of the calculation result to the mobile body exchange 1, which adjusts the order number and transmits the time corresponding to the necessary offset. The mobile body exchange 1 sends the next packet having the adjusted order number at the adjusted transmission time.

Filed: 1994-10-27
Abstract: PURPOSE: To simultaneously oscillate a semiconductor laser in a prescribed plurality of wavelengths, to miniaturize the laser and to lower the production cost of the laser by a method wherein a periodical phase shift is provided in the diffraction grating of the semiconductor laser and a plurality of reflection peaks are provided in the reflection spectrum of the diffraction grating. CONSTITUTION: A diffraction grating 9 is held formed on the upper surface of an n-type InP clad layer 2 by an electron beam exposure method and etching, for example, prior to a crystal growth of an n-type InGaAsP guide layer 3 and a period A corresponding to the primary diffraction grating is about 240nm. When a periodical phase shift is provided in the diffraction grating, the threshold gain of a semiconductor laser, which is oscillated in a plurality of wavelengths in every period M, is reduced and it becomes possible to produce simultaneously a laser beam of a plurality of wavelengths. Moreover, as this period M is decided by the period of the phase shift, a plurality of wavelengths, which are simultaneously oscillated, can be selected by selecting properly the period of the diffraction grating and the period of the phase shift.  Accordingly, a multitude of the gain peak wavelengths of an active layer in correspondence with the wavelengths of the laser, whose threshold gain is reduced, are reduced and the number of wavelengths, which can be simultaneously oscillated, is increased.

Abstract: PURPOSE:To reduce a source resistance by forming a first uniform semiconductor layer, a superlattice layer which varies film thickness ratios of two semiconductor layers gradually, and a second uniform semiconductor layer on a substrate and further, by causing the first and second uniform semiconductor layers to be made from the same materials as those of the semiconductor layers adjacent to the above two layers or causing respective energy values in their conduction bands to be almost equal. CONSTITUTION:An undoped GaAs layer 2, an undoped Al0.3Ga0.7As layer 3, an n<+> type Al0.3Ga0.7 As layer 4, an n<+> type Al0.3Ga0.7As/n<+> type GaAs superlattice layer 5, an undoped Al0.3Ga0.7As/ undoped GaAs superlattice layer 6, and an n<+> type GaAs layer 7 are formed one after another on a semi-insulating GaAs substrate 1 through epitaxial growth. This device allows the uniform semiconductor layers 4 and 7 to be made from the same materials as those of the semiconductor layers which have large film thickness ratios at adjoining parts of the superlattice layers 5 and 6 adjacent to the above layers 4 and 7. In the case where the layers 4 and 7 are not made from the same materials as those of the superlattice layers, it only the energy values in their conduction bands are roughly equal, a similar effect on this matter is obtained. As this device is manufactured by a MBE technique on condition that a cell temperature is held constant, it is superior in the film thickness and the stability of the semiconductor layers as well as the controllability of impurity doping levels.
