Title: Method and device for sputtering
Inventor: OGINO ETSUO
IPC: C23C14/34
Filed: 1989-11-24
Abstract: PURPOSE:To coat a substrate with a film at a stable and high rate by allowing a target material sputtered by the inert gas ion generated by the specified first process to react with the reactive gas ion generated by the second process. CONSTITUTION:The electron generated in a first accelerated beam source 6a is drawn into a vacuum vessel 1, and allowed to collide with an inert gas to produce plasma 15 contg. the inert gas ion in the vicinity of the surface of a target material 3. The inert gas ion is accelerated by a sputtering cathode 2 and allowed to collide with the material 3 which is sputtered. As the second process in succession to the first process, the electron generated in the second accelerated plasma electron beam source 6b is allowed to collide with a reactive gas 14 to produce the second plasma 16. The sputtered material 3 is passed through the plasma 16 and subjected to a reaction to coat the substrate 20 with the compd. of the material 3.

Title: Air conditioner
Inventor: KASANO KATSUMI
IPC: F24F11/02
Filed: 1989-11-24
Abstract: PURPOSE:To save time in re-turning ON a switch or inspecting the cause of a stop of operation, by designing a protective circuit operated by an overcurrent relay for a compressor so that the first operation of the protective circuit comprises stopping only the compressor and, after several seconds, automatically returning the compressor into a normal operation, whereas the second operation of the protective circuit comprises an ordinary protective action. CONSTITUTION:An abnormality indicating circuit based on an operation of an overcurrent relay 10 for a compressor motor 1 is so designed that the first operation of the circuit does not include an ordinary protective action but comprises stopping only the motor 1 and, after a predetermined lapse of time, restarting the motor 1, whereas the second operation of the circuit comprises an ordinary protective action, similar to that of other protective devices, to operate abnormality indication lamps 8, 9 and stopping an air conditioner. Consequently, when a liquid compression cycle is carried out upon starting an air conditioner due to a large amount of a refrigerant liquid being accumulated in the compressor, as in the case of starting the air conditioner after a long rest, an operation of the relay 10 in response to an overcurrent leads to a stopping of the motor 1 only. In this instance, the lamps 8, 9 are not operated, and the air conditioner is not stopped. The motor 1 thus stopped is then automatically restarted into an normal operation.

Title: Manufacture of semiconductor device
Inventor: UGA KIMIHARU
IPC: H01L21/28
Filed: 1989-11-24
Abstract: PURPOSE:To completely destroy the natural oxide film generating between a silicon substrate and a polycrystalline silicon film even on a contact part having a narrow groove width, and to make it possible to suppress the contact resistance on an interface by a method wherein the polycrystalline silicon film, with which the contact part is constituted, is formed in two stages. CONSTITUTION:The resistance of a polycrystalline silicon film 4a is lowered by ion-implanting impurities from above the polycrystalline silicon film 4a which is formed on contact groove parts 10a and 10b and an oxide film 3 in such an extent wherein the thickness of the contact groove part 10a is not increased, and at the same time, the natural oxide film located between impurity diffusion layers 2a and 2b and the film 4a is destroyed. A polycrystalline silicon film 4b is formed again on the film 4a, the resistance-lowered natural oxide film of the film 4b is destroyed in the same manner as above, and finally, polycrystalline silicon films 4c and 4d are formed. Consequently, as the resistance component between a semiconductor substrate 1 and the wiring layer does not become larger because the natural oxide film is completely destroyed, the deterioration of characteristics of the semiconductor element can be prevented even when a narrow-width contact section is formed.

Title: Magnetic recorder/reproducer
Inventor: FUKAMI TADASHI
IPC: G11B5/09
Filed: 1992-10-19
Abstract: PURPOSE:To perform write after read without impairing a valuable audio signal by controlling an operation of recording means in response to an error rate of a reproduced audio signal. CONSTITUTION:A reproduced signal processor 30 detects an error, and corrects the error-detected audio signal by C1 and C2 codes having error correction codes. In this case, the processor 30 starts a logic level of an error process signal DD at a timing of error-corrected audio data, and a system controller 10 counts rising of the signal DD in an interleaving period. Thus, the controller 10 switches over the control data to be output to a record signal generator 24 when an error rate is deteriorated by a predetermined value or more, and immediately controls to stop a recording operation.

Title: Scale
Inventor: YAMAMOTO KEISHO
IPC: G01D5/36
Filed: 1988-12-02
Abstract: PURPOSE:To control a position where resolving power in an Angstrom -unit is high by observing the crystal lattice of a single crystal member on the basis of the output of an intensity meter and detecting the moving position or quantity of a moving part on the basis of the lattice distance of the single crystal member. CONSTITUTION:The X-rays from an irradiation means 7 are applied to an intensity meter 8 through the third - first single crystal members 6, 5, 3 (formed along the straight moving direction of the straight moving part 2 of an X-axis precise straight moving mechanism through a piezoelectric element 4) arranged at an equal interval. When the straight moving part 2 is moved by the indication from a microcomputer 10, said straight moving part 2 shields the passage of said X-rays and a silicon crystal lattice intermittently. Therefore, the output of the intensity meter 8 is changed at the cycle corresponding to a single crystal lattice distance. A wave memory 9 detects the trough and ridge parts of the output of the intensity meter 8 to perform counting. This counting direction is changed over according to the straight moving direction of the straight moving part 2 given from the microcomputer 10. The microcomputer 10 multiplies the count value in the memory 9 by the lattice distance of the single crystal member 3 to calculate the moving quantity and position of the straight moving part 2.

Filed: 1990-11-12
Abstract: PURPOSE:To enable three-dimensional image of very high quality to be easily obtained by forming a device with a pair of right and left synchronous projectors, and a light receiving surface formed with a directional reflection body. CONSTITUTION:This three-dimensional image device comprises a pair of projection devices 2 and 3 such as projectors laid near the right and left eyes of a subject 1, and a light receiving surface 4 formed with a directional reflection body. The directional reflection body has an optical axis of reflected light approximately equal to the optical axis of projected light, and a reflection angle of high directivity different from a conventional screen. It follows, therefore, that the reflected light of image projected from the right and left projection devices 2 and 3 such as projectors near the right and left eyes of the subject 1, is intensely incident to the right and left eyes in such a way that light from the left projection device 2 enters the left eye only and light from the right projection device 3 enters the right eye only. In addition, three-dimensional image of high quality can be obtained, due to parallax between the devices 2 and 3. According to this construction, three-dimensional image of very high quality completely unavailable in an ordinary diffusion light receiving surface can be easily obtained.
