Title: Transmittable video screen
Inventor: OOGOSHI AKIO
IPC: G03B21/62
Filed: 1981-10-30
Abstract: PURPOSE:To obtain an image of high quality by working both surfaces of a screen for rear projection using plural video light sources into a lens shape and properly setting the separation and diffusion angle of projected light, and thus eliminating brightness difference and color difference. CONSTITUTION:A transmittable screen 7 for a rear projection type video projector using video light sources of R, G and B three colors consists of a Fresnel lens 8 on the light source side and a lens 9 having numbers of semicylindrical lens surfaces 9a on the opposite surface to the lens 8. On one surface of the lens 9 on the observer's side, three concave lens surfaces 9b as many as projection lens systems are provided adjacently to one another nearly in the center of the area of each lens surface 9a, and its scattering characteristics are set properly. Thus, brightness unevenness, a phase shift, and a color shift are eliminated.

Title: Device for suppressing generation of scattered sound wave
Inventor: TAKAGI SHIGERU
IPC: G10K11/178
Filed: 1993-07-14
Abstract: PURPOSE:To provide the device which is small in size and light in weight and is capable of suppressing scattered sound waves without increasing flow noises regardless of a pressure change of a medium for propagating the sound waves. CONSTITUTION:This device has a diaphragm 6 array disposed on a surface 1 of an object, a wave receiver 3 disposed on this diaphragm 6 array, a control signal generating section 4 which is inputted with a sound pressure signal from this wave receiver 3 and outputs a control signal and a diaphragm array driving power source 5 which is inputted with the control signal from this generating section 4 and drives the diaphragm 6 array. As a result, the diaphragm 6 array is vibrated in correspondence to the sound pressure signal propagated to the diaphragm 6 array and, therefore, the scattered sound waves generated by the object are suppressed by the small and lightweight device without increasing the flow noises regardless of the pressure change of the medium for propagating the sound waves. The capacity to evade from the sonars, etc., of the object is thus improved.

Title: Method for correcting polarity of current sensor
Inventor: OTOMO KATSUYA
IPC: G01R31/08
Filed: 1992-07-01
Abstract: PURPOSE:To prevent the polarity of current sensors from being inverted even when the sensors are erroneously installed by storing in advance the polarity of each sensor in polarity memories after discriminating the polarity from normally induced currents before staring current measurement after installing the sensors and correcting the polarity of currents in accordance with the stored polarity at the time of measuring the currents. CONSTITUTION:Before starting current measurement after installing current sensors 12a-12e, normally induced currents are detected with the sensors 12a-12e and the polarity of each sensor 12a-12e is discriminated from the detected induced currents. The discriminated polarity of each sensor 12a-12e is stored in polarity memories 14a-14e. The sensors 12a-12e detect induced currents and a phase inverting section 15 inverts the phases of the detected induced currents in accordance with the polarity of each sensor stored in the memories 14a-14e. Therefore, no fault occurs even when the direction of current sensors or polarity of wiring is mistaken at the time of installing the sensors.

Title: Surface form heat emitting body
Inventor: YAMASHITA KAZUO
IPC: H05B3/26
Filed: 1989-07-05
Abstract: PURPOSE:To accomplish a surface-shaped heat emitting body, which is equipped with quick heating capacity and high temp. radiation and is excellent in the mechanical strength, by furnishing heat emitting body over the surface of a heat resistant base board having a number of through holes. CONSTITUTION:A heat resistant base board 1 made of heat resistant ceramic is provided with a number of through holes 2. These through holes may be in regular arrangement with the same size such as in honeycomb structure. Heat emitting body 3 is mounted on this base board 1 so as to constitute a surface-shaped heat emitting body 5. After the heat emitting body 3 is mounted so as not to move, it is secured with a fixture. Because of minor contacting area of the body 3 and base board 1 between, heat radiation due to thermal conduction is small, and the body 3 attains a high temp. in a short time. Accordingly the radiation due to high temp. starts shortly after the power is put on.

Title: Controlling method for roll eccentricity
Inventor: KONDOU KATSUYA
IPC: B21B37/66
Filed: 1981-10-30
Abstract: PURPOSE:To compensate the delay of response in a controlling system, and to effectively suppress fluctuations of sheet thickness, by putting a signal, obtained by setting the starting position of one revolution to zero point, as a roll-eccentricity controlling signal after shifting the phase of a roll eccentricity signal of a rolling mill. CONSTITUTION:Output signals of a thickness gauge 4 or a rolling load gauge 3 at the outlet of a rolling mill 2 are fed to a roll-eccentricity controlling device 5, to calculate a roll eccentricity signal synchronized to one revolution of the roll. A roll eccentricity signal in this time range is fed to a correcting arithmetic device 8, to obtain a roll-eccentricity controlling signal in which the starting point of one revolution is set to the zero point after shifting the phase of said roll eccentricity signal. A sheet thickness control is performed by feeding this controlling signal to a draft position controlling device 6 and, as required, a tension controlling device 7. Thus a highly accurate sheet-thickness-control without a delay of reponse is performed.

Title: Device and method for forming film
Inventor: TERUNUMA KOICHI
IPC: H01F41/18
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To provide a device and method for forming film by which an element having superior characteristics and having a multilayered film structure can be formed, by preventing the contamination of substrates when the substrates pass through a transportation chamber. SOLUTION: A multilayered film is formed on a substrate 1 by using a film forming device having a plurality of treatment chambers (a cleaning chamber 20, a first film forming chamber 30, and a second film forming chamber 40). A substrate 1 passes through a transportation chamber 50 when the substrate 1 is moved among the treatment chambers. When the substrate 1 passes through the chamber 50, an inert gas, such as the argon gas, etc., is introduced to the chamber 50 so that the substrate 1 may pass through the chamber 50 in an inert gas atmosphere. Therefor, contamination problems, such as the moisture adsorption, etc., which conventionally occur when the substrate 1 passes through the chamber 50 can be reduced, and the quality grade and stability of a formed film can be improved.
