Inventor: WAKABAYASHI TORU
IPC: H02K16/00
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To provide a concentric multishaft motor in which the effect of mutual vibration of a plurality of rotor shafts is eliminated and the run out is reduced at the output part of rotor shaft. SOLUTION: The concentric multishaft motor comprises bearings 4a-4d for coupling the inner circumference of the rotor shaft 1a of one rotor 11 and the outer circumference of the output shaft 1d of the other rotor 12 with a hollow frame 7 integrated with a frame 5.

Title: Solid-state image pickup device
Inventor: ANDO FUMIHIKO
IPC: H04N5/335
Filed: 1984-12-26
Abstract: PURPOSE:To improve the S/N to pick up images by transmitting a pulse signal corresponding to the number of incident photons by plural light receiving means which are arranged one-dimensionally at least and counting and holding and reading out the pulse signal with an optional period. CONSTITUTION:A line sensor is constituted on a single wafer in accordance with an IC process. Optical sensor parts 8A-8N transmit the pulse signal corresponding to the number of incident photons, and 16-23-bit pulse counters 10A-10N count pulses of the transmitted pulse signal. First, the pulse signal corresponding to the number of incident photons is led from photodiodes 12A-12N to counters 10A-10N for 1/30 seconds corresponding to one frame, and counted values are read out successively with a horizontal scanning circuit 14 when counting is terminated. After reading, the contents of counters are reset to zero, and hereafter, the same operation is repeated. Thus, the illuminance of a light receiving surface is converted directly to a digital signal in each picture element unit and is outputted to pickup images with an impoved S/N.

Title: Manufacture of semiconductor device
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1990-10-15
Abstract: PURPOSE:To realize the denaturation whose stability and uniformity are excellent by a method wherein carbon which is used to denature the surface of an inorganic SOG film is supplied from an atmospheric gas for a plasma treatment and the flow rate of a gas is kept constant. CONSTITUTION:A silicon substrate is coated with an inorganic SOG film; a prebaking operation is executed; a plasma treatment is executed under prescribed conditions of CO2 as an atmospheric gas. Then, a postbaking operation is executed to promote the substitution of a C-O bond structure in the inorganic SOG film and to disconnect a solvent. After that, even when the substrate is humidified forcibly, chemically and physically adsorbed water is reduced remarkably. In this manner, the flow rate of a gas which contains carbon used to denature the surface of the substrate is controlled; the concentration of the gas is held to be definite; a denaturation treatment is executed with good reproducibility. Thereby, it is possible to denature the inorganic glass film with good stability and with good uniformity by using an existing apparatus.

Title: Formation of vapor deposited film
Inventor: MASAKI YASUSHI
IPC: C23C14/34
Filed: 1989-10-20
Abstract: PURPOSE:To form a vapor deposited film having uniform film thickness on the whole surface of a substrate by forming a vapor deposited film whose thickness is smaller in the periphery than in the intermediate region on the surface of a substrate by means of sputtering and further forming a vapor deposited film on the periphery alone. CONSTITUTION:When a target 1 is sputtered under vacuum and a vapor deposited film 4 is formed on the whole surface of a substrate 2, film thickness is reduced in the peripheral part of the substrate 2 though it is uniform within an effective range. Therefore, the sputtering of the target 1 is carried out by interposing a shutter 3 slightly larger than the effective range between the target 1 and the substrate 2, by which the vapor deposited film 4 is formed on the peripheral part alone. By this method, the vapor deposited film 4 in which film thickness (t) is uniformized can be formed on the whole surface of the substrate 2.

IPC: G03G15/01
Filed: 1984-12-26
Abstract: PURPOSE:To switch developing devices automatically in accordance with the state of a developer to reduce the number of times of toner supply by providing the first detecting means which detects the classification of each developing device and a control means which controls switching among developing devices in accordance with the output of the second means which detects the state of the developer in each developing device. CONSTITUTION:When a developing device comes to a position facing a sensor part 31 of a toner remainder detecting means 30, it is detected whether there is a toner in a hopper of the developing device or not. If a CPU discriminates 'toner presence' because a photodetector 33 does not receive light, a normal copy sequence is executed; but if the CPU discriminates 'toner absence' by the light reception detection signal of the photodetector 33, the classification of the developing device placed in the remainder detection position at present is detected. At this time, the position is detected by a stop position detecting means 20, and the classification is detected by a developing device classification detecting means 17. Next, the CPU discriminates whether there is a developing device which is in the same classification as the developing device placed in the remainder detection position and has a lower priority level or not.

The receiving signal of said antenna 13 is inputted to an operation appara tus 20 through a receiver 12 to repeat operation performing sampling by receiving intensity plural times and sampling data by receiving intensity are extracted over many points on an x-axis. Then, the sampling data at respective points are converted to the signals of the display colors corresponding to the order of a size on a t-axis and the echo image of a hyperbolic curve is displayed on a display device 21. When the echo image is displayed by this method, a dummy echo image is formed by the apparatus 20 to be displayed on the apparatus 21. By this method, the position of the underground embedded article can be detected with good accuracy.

Abstract: PURPOSE: To provide an image fixing device which prevents the soiling of the rear face of recording sheet, prevents a device from being large-sized and does not obstruct the adhesivity and the carrying performance of the recording sheet. CONSTITUTION: The recording sheet passes a nip 12 between a heating roll 13 and a pressure roll 14, so that unfixed toner on the recording sheet is fixed. Waste toner 18 stuck from the recording sheet to the heating roll 13 is pressed by an upper peeling pawl 16 and is firmly restuck on the heating roll 13, and then is stuck on the pressure roll 14 by the nip 12. However, since a blade-like cleaning part 24 is provided at a position corresponding to the upper peeling pawl 16 in the axial direction of the rolls 13 and 14, it removes the waste toner 18. The cleaning part 24 is integrally provided at a peeling and cleaning part 20 together with lower peeling pawls 25 and 25. When the recording sheet passing the nip 12 is stuck on the roll 13 or 14, the peeling pawl 16 or the pawls 25 and 25 peel it.

Filed: 1989-10-20
Abstract: PURPOSE:To measure the direction of an air flow with high accuracy by detecting a conductive thread slanting by the air flow and contacting a conductor arranged on the surface of a ring body. CONSTITUTION:A fixed support rod 10 in an inverted L shape is arranged in a clean room, a movable support rod 11 is engaged with it, and the ring body 12 is fixed and supported atop.

When a measurement is taken, the conductive thread 13 is made to droop and adjusted so as to securely pass the center of the ring body 12 while clean air 3 is not supplied from a clean air blowout opening 1. Then the air 3 is blown out of the blowout opening 1 and if the air 3 flows laterally under the influence of the blowout opening 5 although the air 3 is expected desirably upward, the thread 13 slants at an angle alpha. At this time, an operator stands at a distance from the thread 13 and moves the support rod 11 upward and then the direction of the air flow can accurately be measured when a state wherein one of the conductors 15 contacts the thread 13 to make an electric connection is detected 19.
