Title: Film forming method by sputtering and film forming device by sputtering
Inventor: TADA YOSHIYUKI
IPC: C23C14/35
Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To provide a film forming device by sputtering which executes film formation at always consistent and stable characteristics corresponding to the erosion of a target. SOLUTION: A driving electric field and a driving magnetic field orthogonal with this driving electric field are impressed under a discharge gaseous atmosphere. Electrons come into collision against discharge gaseous molecules by trochoide motion. The positive ions of plasma generated by the glow discharge collide against the surface of the target 1 and the thin film of the sprung out atoms of the target 1 is formed on a wafer. A sputtering region is expanded over nearly the entire surface of the target 1 by rotation of an electromagnet coil 3 fixed to a rotary plate 4 disposed freely rotatably on the rear surface of the target 1, by which the driving magnetic field is formed.  The excitation electric power supplied to the electromagnet coil 3 is controlled in such a manner that the magnetic field intensity on the surface of the target 1 is kept always constant according to the erosion state on the surface with lapse of time. The formation of the thin film is thus executed on a wafer under the film forming conditions contact with lapse of time. The time for exchange of the target 1 in the control state of a DC power source 10 is exactly decided.

Title: Electrophotographic method
Inventor: AZUMA TAKETOSHI
IPC: G03G21/00
Filed: 1992-07-21
Abstract: PURPOSE:To form images with high reliability and small energy at a low cost without contamination in a device, paper jam, rear transfer to paper, etc., by using a specific photosensitive body and an electrostatic charger or destaticizing brush, etc., for destaticizing the charges of the photosensitive body after transfer. CONSTITUTION:The photosensitive body 1 having a photosensitive layer consisting of hydrogenated and/or fluorinated amorphous silicon is used. After the surface of the photosensitive body 1 is uniformly electrostatically charged by the electrostatic charger 2, the photosensitive body is exposed by the light from an image input device 3 to form an electrostatic latent image which is then converted to the visible image by a developing device 4. The formed visible image is brought into contact under pressurization with paper 6 by a pressure transfer roll 5, by which the transferring and fixing of the toner image are executed. The charges remaining on the photosensitive body 1 are removed by the destaticizing device 9. Since the electrostatic charger or the destaticizing brush or a destaticizing blade is used as the destaticizing device 9, the charges remaining on the photosensitive body surface are completely removed and the film thickness on the surface layer of the photosensitive body 1 is increased. Then, there is no adhesion of the toners on the rear surface of the pressure transfer roll and the generation of the paper jam and transfer of the image to the rear surface of the paper occurring in the adhered toner is obviated.

Filed: 1989-08-21
Abstract: PURPOSE:To correctly detect the presence/absence of toner in an image forming device where a replaceable toner cartridge is used by providing a magnetic permeability sensor made to press-contact with the outer peripheral bottom or outside bottom of a toner storage. CONSTITUTION:A magnetic permeability sensor 29 is made to press-contact with the outer peripheral bottom or outside bottom of the toner storage 8 provided attachably to/detachably from the image forming device main body 1. When magnetic toner sufficiently remains in the toner storage 8, high permeability is detected by the permiability sensor 29, whereas when the toner is consumed in the toner storage 8 as image formation proceeds, the toner does not remain in the vicinity of the permeability sensor 29 and low permiability is detected by the permiability sensor 29. Thus, the presence/absence of the toner in the toner storage can be detected based on the output of the permiability sensor without contact with the toner itself.

Title: Disk record reproducer
Inventor: KOBAYASHI AKIRA
IPC: G11B19/22
Filed: 1982-12-09
Abstract: PURPOSE:To stop quickly the revolutions of a disk and to improve the operability of a disk record reproducer by varying the output period of a brake pulse which is supplied to a disk driving motor in response to the number of revolutions of the disk. CONSTITUTION:The output of a limiter amplifier 35 is supplied to a cycle/voltage converter 41. The output voltage of the converter 41 is gradually reduced as the cycle of the input pulse becomes longer when a control input terminal is set at a high level. Then the output level of the converter 41 is held and then supplied to a brake pulse generating circuit 31. A comparator 311 of the circuit 31 supplies the brake pulse to a motor 12 via a motor driving circuit 30 for a prescribed period during which the signal Si supplied to a non-inverse terminal exceeds the reference voltage VTH. As a result, the output period of the brake pulse is varied in response to the number of revolutions of the corresponding motor 12 of that time point when a pickup 13 is positioned with a distance gamma apart from the center of a disk 11. Thus the brake torque is given to the motor 12 in response to its number of revolutions.

Title: Communication device of automatic driving truck
Inventor: TOKUI KAZUO
IPC: H04B10/11
Filed: 1982-12-09
Abstract: PURPOSE:To attain communication despite the discordance of optical axes between a light transmitting part and a light receiving part, by providing communication devices consisting of a light transmitting part where the signal modulation light is diffused and a wide-angle light receiving part where said modulation light is received at the desired positions of an automatic driving truck and a building, respectively. CONSTITUTION:The signal sent from a central controller 1 is modulated at an optical modulating/demodulating part 3 of an optical transmitting/receiving device 2 of the center side provided on a wall, a ceiling, etc. and then transmitted from a light transmitting/receiving part 4. The transmitted light is diffused in a wide angle and reflected by a wall, a floor and a ceiling to be received at a light transmitting/receiving part 6 of automatic driving trucks 5A and 5B respectively. This received light is demodulated at an optical modulating/demodulating part 7. In this case, the coincidence of optical axes is not required since the part 6 has a wide angle. The transmission signal consists of an address of the truck 5A or 5B, the control data to be given to the truck 5A or 5B, and a data request. Therefore after demodulating, only the automatic driving truck of the corresponding address receives the control signal, and the control signal is transmitted to a truck controller. Thus the truck has the corresponding working.
