Title: Digital fm modulation circuit
Inventor: SASAKI TAKAYUKI
IPC: H04N5/92
Filed: 1983-10-31
Abstract: PURPOSE:To eliminate the need for an ROM and to miniaturize the titled circuit by inverting the polarity of an integration output of an integration circuit at each repetition from a prescribed value to a prescribed value with a carry signal. CONSTITUTION:An output data word of an integration circuit 50 is fed to an exclusive OR gate circuit 11. An MSB of an output data of the integration circuit 50 and a carry signal CA obtained when the integration circuit 50 overflows are fed to the exclusive OR gate 12. Then an output signal OG of the gate 12 is fed to the gate 11 and also fed to an adder circuit 13 together with the output of the gate 11. That is, the output data word of the integration circuit 50 is extracted by the signal OG when the level of the data word is logical ''1'' while the polarity is inverted and the data word is extracted while the polarity is remained the same when the level is logical ''0'' at an output terminal 14 respectively. The output data becomes a triangle wave signal (digital signal) subjected to frequency modulation in response to the level of the input data.

Title: Method for preventing flowing-out of slag
Inventor: HIGUCHI YOSHIHIKO
IPC: C21C5/46
Filed: 1988-08-17
Abstract: PURPOSE:To prevent flowing-out caused by enclosing slag on molten steel surface into eddy by applying static magnetic field before developing the eddy in the molten steel at steel tapping hole and rotating magnetic field after developing the eddy to the molten steel pouring stream from a steel tapping vessel. CONSTITUTION:The surface of the molten steel 3 in the ladle 1 is covered with the slag 4 to prevent heat radiation, and this molten steel 3 is poured into a tundish 5 in order from the steel tapping hole 3 at the bottom part in the ladle 1 and further, poured into a mold, to cast a cast slab. At the time of pouring the molten steel 3 into the tundish 5, the static magnetic field is applied to vertical direction to the molten steel pouring stream 6 with a magnet 7 at the steel tapping hole 2 to restrain the development of the eddy at the steel tapping hole 2. At the time of developing the eddy in the molten steel 3 just above the steel tapping hole 2 by lowering the molten steel level in the end period of the steel tapping, while applying the rotating magnetic field to reverse direction to the rotating direction of the eddy to the molten steel pouring stream 6, the molten steel is tapped. By this method, the development of the eddy is surely prevented in the end period of the steel tapping to reduce the flowing-out of the slag 4.

Title: Receiving and transmitting circuit for data using buffer memory
Inventor: MIURA KENJI
IPC: H04L12/28
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To decrease the number of buffers by using a buffer, used to fetch transmission line data with an in-device master clock, and a buffer for processing in the device in common. SOLUTION: Mutually independent and different two timing generators 5-4 and 5-7 generate outputs so that the clock extracted from the transmission line data is used as the write-side clock of the buffer memory of a storage type processing part 5-2 and the master clock in the device is used as the read- side clock. This read-side clock matches the internal process sequence of the write-side clock and specific processing is performed. The write-side clock is extracted from data having jitters generated on the transmission line and an interface means (FP frame pulse) controls the phases between the outputs and inputs of the two timing generators (5-4 and 5-7) so that the influence of the jitters of the write-side clock does not appear in the read-side clock.

Title: Manufacture of semiconductor device
Inventor: SUGIMOTO SHIGEKI
IPC: H01L23/522
Filed: 1996-08-02
Abstract: PROBLEM TO BE SOLVED: To reduce flaws, unevenness, etc., of a foundation by forming a second conductive layer on an insulation film clear of a protection film and on a conductive film with a filled connection hole. SOLUTION: Since a second SiO2 film 27, a Ti film 30 and a TiN film 32 are hardly etched by hydrofluoric acid vapor, a BPSG film 28 alone is selectively removed. A first wiring 26 of a lower layer wiring and a second wiring of an upper layer wiring are electrically connected through a conductive film of a Ti film 30, a TIN film 31 and a W film 32 with a filled contact hole 29. When the contact hole 29 is buried for electrical connection, the Tin film 30, the TiN film 31 and the W film 32 formed in a place excepting the contact hole 29 are polished by CPM method and removed. Even if flaws and unevenness during processing are generated in the BPSG film 28 of a protection film which is a foundation of the Ti film 30 during polishing and removal by the CMP method, the PBSG film 28 is selectively etched away. Therefore, flaws and unevenness do not remain in the upper surface of the second SiO2 film 27.

Filed: 1986-08-29
Abstract: PURPOSE:To accurately detect only dust, by providing the first light emitting means, the second light emitting means and the second light receiving means receiving light when the second detection light is refracted in a detection area. CONSTITUTION:At first, when air containing dust is introduced into a detection area, the detection light emitted from the first light emitting means is weakened and the intensity of the light received by the first light receiving means is lowered. The detection light emitted from the second light emitting means is also weakened but not received by the second light receiving means because not refracted. Next, when air containing water droplets is introduced into the detection area, the first detection light is scattered and the intensity of the light received by the first light receiving means is lowered. Then, the second detection light refracted by water droplets is received by the second light receiving means. When air containing dust is introduced into the detection area as mentioned above, the intensity of the light received by the first light receiving means is lowered and, when air containing water droplets is introduced, the light receiving sensitivity of the first light receiving means is lowered and the second detection light is received by the second light receiving means. That is, the light receiving state of each of the light receiving means is changed corresponding to whether a substance to be detected is dust or a water droplet.

Filed: 1990-08-03
Abstract: PURPOSE:To improve the utilization efficiency of light such as sunlight and to enable mass-culture of the subject life by converting the light into a visible light having a wavelength range effective for photo-synthetic reaction using a specific means or selectively concentrating the light. CONSTITUTION:Ultraviolet ray having a wavelength of <=350nm in sunlight or light emitted from an artificial light source is absorbed with a fluorescent emitter 4 such as a phosphate fluorescent material coated on the surface of a culture vessel 1 composed of a transparent plastic tube, etc., and converted into a visible light having a wavelength effective for photo-synthetic reaction. The light is emitted as blue light having a wavelength of 460nm and radiated to green algae, blue algae, etc. As an alternative method, the light is selectively concentrated with a diffraction grating. The light having the above wavelength is absorbed together with the visible light of >=350nm wavelength with a photo- synthetic pigment of the green algae, etc., to proceed the photo-synthetic reaction. Since far infrared ray raises the temperature of the culture liquid 2, the temperature of the culture system is controlled by a temperature controlling system 8. The utilization efficiency of light can be improved to enable the mass-culture of the life.
