Title: Image forming method
Inventor: ANDOU ITSUROU
IPC: G03G5/02
Filed: 1983-06-22
Abstract: PURPOSE:To form an inverted image by an electrophotographic method which requires no electrostatic charge device, by making a non-insulating magnetic toner held on a developing means provided with a magnet on the inside contact to the surface of a transparent insulating layer side of a photosensitive body, and forming a toner image. CONSTITUTION:A light of a lamp 6 is illuminated through a transparent original 5 from a transparent insulating layer side of a photosensitive body 1. A developing roller 9 is slid and rubbed against the surface of an insulating layer 4 of this photosensitive body 1. The developing roller 9 has a magnet in its inside, and attracts a non-insulating magnetic toner 10 to its surface by a magnetic force and holds it. In said state, when the developing roller 9 is slid and rubbed against the surface of the insulating layer side of the photosensitive body 1, a toner adheres to the surface part of the photosensitive body on an exposing part 7, and on the other hand, the toner does not adhere to the surface part of the photosensitive part on a non-exposing part 8. Accordingly, in this way, it becomes possible to form an inverted image by an electrophotographic method which does not require an electrostatic charge device.

Title: Bearing exhaust oil collecting device for oil-cooled type screw compressor
Inventor: MORI HIDETOMO
IPC: F04C18/16
Filed: 1979-09-05
Abstract: PURPOSE: To prevent the exhaust oil from scattering in a gas-sucking route and thereby heating the sucked gas by introducing the exhaust oil from the bearing on the gas-sucking side into a chamber in which the capacity is not changed.  
     CONSTITUTION: A passage 29 is provided so that the exhaust oil from a bearing on the suction side is introduced into a chamber 34 which is a transporting stroke with no change in capacity between the suction and compression strokes of a female rotor (omitted in the figure). The stroke with no change in capacity until the chamber of the female rotor (omitted in the figure) intercepts the communication with a suction route 10 and the compression stroke is commenced is called the transporting stroke, and the pressure in the chamber 34 of this stroke is nearly equal to the suction pressure. The exhaust-oil chamber 24 on the side of a male rotor and the exhaust-oil chamber 24' on the side of the female rotor are communicated with each other, while the chamber 24' is further communicated with the chamber 34 through the passage 29. Accordingly, much of the heated exhaust oil from the bearing on the suction side is exhausted in the female rotor chamber (not shown) in the transporting stroke whose communication with the suction route 10 is intercepted and, therefore, the scattering of the oil into the flow-in gas from the suction route 10 is reduced, whereby the reduction of the quantity of the sucked air can be prevented.

Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of a check by reading each of ink images such as yellow, magenta and black from the reflected light of a blue color light emitted to a print image and each of ink images such as cyan, magenta and black from the reflected light of a yellow color light. SOLUTION: A light source driver outputs a light source blinking signal to an image reading part 2 based on a control signal from a control part each time a web W travels to be displaced by a predetermined amount. The image reading part 2 makes a blue color light emitting diode 21B and a yellow color light emitting diode 21Y emit lights based on the light source blinking signal and thereby the web W is exposed to the light. The light from the blue color light emitting diode 21B is reflected by the print image portion of the cyan ink and the white texture of the web W to be a 'bright' reflected light while the light is adsorbed by the portion other than the bright portion to be a 'dark' reflected light.  The light of the yellow light emitting diode 21Y is reflected by the print image portion of the yellow ink and the white texture of the web W to be a 'bright' reflected light, while the light is absorbed by the portion other than the bright portion to be a 'dark' reflected light.

Abstract: PROBLEM TO BE SOLVED: To improve vibrationproof strength in a moving turbine blade provided in the outer peripheral part of a disc of a turbine rotor by forming a blade root part as a saddle-shaped structure, and containing the blade root parts of the adjacent moving turbine blades mutually by the projecting and recessed parts formed on the circumferential surface of the saddle-shaped parts. SOLUTION: In the moving turbine blade, a projecting part 11 and a recessed part 12 are formed on the circumferential surface 13 of a blade root part 1, and these parts are set to such a shape that at the time of assembling the moving turbine blade, the blade root part 1 has no gap in the circumferential direction. When centrifugal force is applied in the direction of an arrow 61, the blade root part 1 is deformed to a broken-line shape 1'. Therefore, at the rest, the adjacent blades come into contact with each other in the circumferential surfaces 13 of the blade root parts 1. By the contact surfaces 51, 52 of the projecting and recessed parts 11, 12, the contact between the blade root parts 1 can be kept.  Especially, the line 91 of center of gravity 91 in the radial direction of the blade is not aligned with the line 9 of center of gravity of the blade root part 1, so that the blade root part 1 is deformed in the circumferetial direction 62. Thus, the projecting and recessed parts 11, 12 are brought into contact with each other to contain the adjacent blade root part 1.

Abstract: PURPOSE:To unnecessitate the use of a mechanical supplementary device such as a tachometer-generator and the like for speed detection of the titled motor by a method wherein a speed signal is obtained by sampling the motor counter electromotive voltage of the non-pulse energized section. CONSTITUTION:A timing circuit 6 generates a differential pulse b at the fall point of the pulse a which will be outputted by a pulse oscillator 5.
