Title: Image forming device
Inventor: IZUMI TAKAO
IPC: G03G15/08
Filed: 1992-02-28
Abstract: PURPOSE:To always form an excellent image by preventing a gap regulation member from directly abutting on an image carrier, preventing the image carrier from being vibrated and suppressing blurring in an exposure and developing process when a developing gap is regulated. CONSTITUTION:At the same time that a mixer 45 and a developing sleeve 41 are started to be rotated by a developing start signal, a guide roll 43 is lifted by a driving mechanism until it abuts on a positioning member 60. As the result, the shaft of the sleeve 41 is moved along the slit of a fixing part and the required developing gap is maintained. Then, when the roll 43 which regulates the developing gap between a photosensitive drum 1 and the sleeve 41 is not directly brought into contact with the drum 1 and it abuts on the positioning member 60 which is provided in addition to the drum 1 and which has the identical surface to the drum 1, the developing gap is decided. Therefore, the developing gap can be regulated without giving impact to the drum 1.

Abstract: PURPOSE:To improve recognition and decision precision and to reduce a heating value by arranging a stage to move a laser beam controller and a semiconductor to a laser beam marker and emitting a laser beam for a prescribed time in synchronization with driving of the stage. CONSTITUTION:The laser beam marker 2 and the laser beam controller 7 are arranged to a tester 1 to decide good or bad of a semiconductor device and the stage 5 having a driving part 6 is arranged thereto.

Abstract: PURPOSE:To simplify a focus control mechanism by using a plate type half mirror arranged so as to reflect a luminous flux from a laser light source on its surface, and passing through the reflected light from an optical disc to generate an astigmatism. CONSTITUTION:A translucent film is formed on one face of a base being a parallel flat plate in the half mirror 20a and about 50% of a divergent luminous flux from a semiconductor laser 2 is reflected on a mirror face 20a. The reflected luminous flux is made incident to a focus lens 8 via a collimate lens 4 and the focus of the lens 8 is controlled by a focus servo mechanism 12. The luminous flux transmitting through the lens 8 is collected on a pit face of an optical disc 10 so as to be a spot, and the luminous flux reflected on the pit face is made incident again to the mirror 20a via the lenses 8 and 4. About 50% of the reflected luminous flux, i.e., about 25% of the luminous flux transmitted from the laser 2 transmits through the mirror 20a and is received by a photodetector 14. The astigmatism occurs to the luminous flux incident to the detector 14 and the focus control mechanism is simplified.

Abstract: PURPOSE:To correct defects without exerting the influence of contamination, etc., on other parts by electrically insulating a defective TFT simply by partially applying heat to a contact part. CONSTITUTION:A semiconductor film consisting of silicon, etc., or a metallic conductive film 2 consisting of aluminum, etc., is formed on an insulating substrate 1 and after an interlayer insulating film 6 is formed thereon, contact holes are opened to a prescribed pattern. The conductive film 2 and a conductive film 8 of an oxide system are electrically conducted if the conductive film 8 is deposited thereon. However, the oxygen in the conductive film 8 of the oxide system diffuses into the conductive film 2 and the insulating film 9 of the oxide system, such as SiO2 and Al2O3 is formed at a contact boundary 9 if heat is partially applied by a laser beam, etc., to the contact regions 9 and 116 of the conductive film 2 and the conductive film 8 of the oxide system. The conductive film 2 and the conductive film 8 of the oxide system are thereby insulated. The picture element of the defective TFT part is the defect of a normally lighting abnormal lamp if the transparent conductive film 117 for driving the picture element is insulated from the drain region 116 in such a manner. The defect of the panel is, thus, inconspicuous.

Title: Magnetic disk device

IPC: G11B21/10
Filed: 1989-02-27
Abstract: PURPOSE:To prevent malfunction from occurring and to improve reliability by providing a signal generation circuit consisting of first and second FFs and first and second AND gates. CONSTITUTION:When an odd signal A0 is inputted, an FF 2A outputs a signal D of L at the trailing edge of the signal, and an FF 1A outputs a signal C of H at the leading edge of the signal. At this time, since the output of an inverter 7 goes to the L, an AND gate 9 outputs no pulse. Since the signal A0 follows a pair of even signals B0, a signal A1 precedes a signal B1 at the next timing. The output of the inverter 7 goes to the L by the input of the signal A1, and the gate 9 outputs a signal E of H. Following that, the FF 1A is reset at the trailing edge by the input of the signal B1, and outputs the signal C of L, and the FF 2A outputs the signal D of H at the leading edge, however, since the output of an inverter 8 goes to the L, an AND gate 10 outputs no pulse. Hereafter, the same operation is performed, and a succeeding signal out of the pairs of signals A and B is masked, and only a preceding signal is taken out one by one, and a signal G can be obtained from an OR gate 11.

Abstract: PURPOSE:To realize multistage gradation expression by providing a parallel planar lens between a photosensitive body and an LED head provided so that it faces to the photosensitive body and using a lens which has a refraction ratio distribution where the refraction ratio is decreased from center toward an outer edge part along with the moving direction of the photosensitive body. CONSTITUTION:A refraction ratio distribution type lens (a Selfoc lens) 3 and a one-way refraction ratio distribution type slab lens 4 as the parallel planar lens are disposed each in parallel to the axis direction of the photosensitive body 1 between the LED head 2 and a photosensitive body drum 1.

Therefore, circular beam shape is changed into elliptical beam shape the minor axis direction which is same as the moving direction of the photosensitive body 1. And besides, since the axis length of the ellipse is changed by changing LED conducting time, the area of a dot is changed and gradation at every dot is safely performed.

IPC: H01J37/28
Filed: 1991-03-08
Abstract: PURPOSE:To prevent generation of displacement in a scanning electron image displayed in a cathode ray tube even at any scanning speed. CONSTITUTION:In order to correct linear displacement of an output current by a change of a scanning speed, a correction signal from a correction signal generating circuit 16 is added to a scanning signal in an addition amplifier 3. Relating to a change of the scanning speed, amplitude of a response magnetic field is changed by changing amplitude of currents flowing in a scanning coil and a deflecting coil of an observing cathode ray tube, but in order to compensate this change, an amplitude adjusting circuit 11 is adjusted by control from a control part 15 to change amplitude of the scanning signal. Further in the scanning signal, the amplitude is adjusted in accordance with acceleration voltage of an electron beam in an acceleration voltage interlocking circuit 12, and in a working distance interlocking circuit 13, amplitude is adjusted in accordance with a change of a distance between a sample and an objective lens. As a result, no displacement of an image is generated synthetically even at arbitrary scanning speed, acceleration voltage and working distance.
