Title: Sound signal processing circuit for television broadcast signal
Inventor: TSUNODA TAKASHI
IPC: H04H40/72
Filed: 1983-04-21
Abstract: PURPOSE:To reproduce sound with good S/N ratio by frequency-converting the 1st sound intermediate frequency signal with an oscillating frequency signal of an automatic frequency control circuit taking a video carrier of an intermediate frequency signal as a reference to obtain the 2nd sound intermediate fequency signal. CONSTITUTION:An automatic frequency control circuit consists of a frequency converting circuit 4, a tuning amplifier 7, a low pass filter 8 and a VCO6. The intermediate frequency signal is applied to the tuning amplifier 5, where the 1st sound intermediate frequency signal having a main sound carrier fs1 and an accessory sound carrier fs2 is tuned and selected, amplified and then fed to a frequency converting circuit 9. The frequency converting circuit 9 balance- modulates an oscillating frequency signal fL of the VCO6 by using the 1st sound intermediate frequency signal, extracts the 2nd sound intermediate frequency signal having the main sound carrier fs1-fL and the accessory sound carrier fs2-fL and supplies the signal to a sound intermediate amplifier circuit 10.

Title: Semiconductor integrated device
Inventor: NOMURA NOBUO
IPC: H01L27/04
Filed: 1990-03-19
Abstract: PURPOSE:To avoid electrostatic breakdown while considering various noise countermeasures by forming power supply pads exclusive for each of a plurality of internal circuits formed onto a chip and mounting resistance elements mutually connecting the power supply pads. CONSTITUTION:Both power supply pads 26, 27 and both grounding pads 28, 29 are connected by resistance elements 46, 47 respectively. Since a section between power terminals 21, 22 (between the power supply pads 26, 27) is connected by the resistance element 46, discharge currents mainly flow through the resistance element 46, thus reducing currents to an internal circuit bonded with the power supply pads 26, 27, then avoiding the electrostatic breakdown of the internal circuit. When a package 20 is incorporated into an equipment, supply currents can be fed at every internal circuit without being subjected to the effect of the resistance element 46 because the power terminals 21, 22 and an external power supply are connected by low impedance, and various noise countermeasures can be executed without trouble. Since the floating capacitance C46, C47 of the resistance elements 46, 47 works as bypass capacitors in addition to the execution of said countermeasures, various noises can further be suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide a coil in which an increase in volume and weight of a power source is extremely suppressed, a leakage flux is reduced and a harmonic control effect is high. SOLUTION: There are combined a ferrite core of a type which is a first magnetic material 1 constituting a close magnetic path, has a hollow part 6 and comprises a middle leg part 1c interposed by this hollow part 6; and a silicon steel plate of a type which comprises a close magnetic path, is a second magnetic material 2 provided with a specific magnetic gap 7 in this magnetic path, and has a single hollow part 6. There are provided a first coil and a second coil wound at a position extending over these first and second magnetic materials and at a position excluding the middle leg part 1c. In the middle leg part 1c of the first magnetic material, a direction of magnetic flux formed by the first coil is different from a direction of magnetic flux formed by the second coil to cancel each other. Thereby, it is possible to obtain a composite coil in which both characteristics of a normal mode and a common mode are provided and further a leakage flux is reduced.

Title: Cad/cam device
Inventor: INABA YUTAKA
IPC: B23K26/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To simplify the work of an operator operating a CAD/CAM device. SOLUTION: The CAD/CAM device selects a straight line 1 as retrieval start data at first, for example. Then, the CAD/CAM device retrieves a straight line 2 which is continuously branched from the straight line 1 and continuous straight lines 3, 4, 5 and 6 are sequentially retrieved from the straight line 2. Then, the straight line 2 is retrieved again next to the straight line 6. In such a case, the CAD/CAM device judges that a specified graphic starting from the straight line 2 and returning to the straight line 2 exists. When a branch point exists in a process for retrieving the straight line in the adjacent position of the straight line 1 from the straight line 1, the operator does not need to judge which straight lines branched from the branch point are to be retrieved.

Title: Sedimentation apparatus
Inventor: KATO ISAMU
IPC: B01D21/30
Filed: 1995-03-28
Abstract: PURPOSE: To provide a sedimentation apparatus performing stable treatment by effectively developing the solid-liquid separation function in a sedimentation tank by performing continuous operation while keeping the inflow amt. of water to the sedimentation tank constant. CONSTITUTION: A raw water pump P1 is operated in constant water quantity to return a part of treated water in a sedimentation tank 4 to a raw water tank 1. The return amt. of treated water is adjusted corresponding to the inflow amt. of raw water or the water level of the raw water tank. By this constitution, the raw water pump is operated in a constant flow rate even when the inflow amp. of raw water fluctuates to make the inflow amt. of water to the sedimentation tank constant. Therefore, the density flow or turbulent flow in the sedimentation tank is prevented by continuous operation to stably obtain treated water of high quality.

Title: Production of optical fiber type polarizer
Inventor: SASAOKA HIDEYORI
IPC: G02B6/024
Filed: 1990-03-20
Abstract: PURPOSE:To obtain a desired quenching ratio of a large value by determining the design of a fiber and the bending diameter of the fiber in such a manner that the polarizer has the bending loss difference and mode coupling coefft. between the polarizations at which the required quenching ratio satisfies specific equation and further adjusting the fiber length. CONSTITUTION:The design of the fiber and the bending diameter of the fiber are so determined that the polarizer has the bending loss difference alpha and mode coupling coefft. (h) between the polarizations satisfying the following equation; ER0 < 10 log10[(alpha/4.3+h)/h] when the required quenching ratio is ER0 (dB). Further, the fiber length is adjusted. Namely the converging value of the quenching ratio is known in the stage when the design of the fiber and the bending diameter of the fiber are determined and, therefore, judgment can be made whether the desired quenching ratio can be obtd. without executing the winding of the fiber. Such a wasteful operation as to adjust the fiber length under such condition under which the desired quenching ratio is not obtainable in spite of increasing the length to any extent is, therefore, saved. The optical fiber type polarizer having the large quenching ratio is formed in a short period of time in this way.

Abstract: PURPOSE:To prevent the pickup of H (hydrogen) at the initial stage of casting by heating the back surface of a coating layer at a specific temperature or more after coating a coating layer provided on the surface of inner lining with Mg base refectory and further with a coating material added with water. CONSTITUTION:The MgO reacts with moisture to produce hydrate which does not fully decompose unless being heated up to 800 deg.C. Therefore, the back surface temp. of the MgO base coating material in the tundish must be kept at >=800 deg.C. Molten steel made to have a prescribed value or lower of carbon content by using a converter is charged into a vacuum degassing apparatus and degassing treatment is executed in a prescribed vacuum degree of a prescribed time to execute dehydrogenetion. As a base material of the tundish for pouring the molten steel, lining with Al2O3-SiO2 base refractory is executed and then, after applying the MgO-base refractory as the coating material on this lining refractory, the inner part of the tundish is heated by a gas burner to execute drying. By this method, the H concn. is not changed after the degassing treatment.
