Title: Automatic tracking apparatus of video tape recorder
Inventor: YON HOO SHIN
IPC: G11B15/467
Filed: 1988-01-11
Abstract: PURPOSE: To automatically adjust tracking by making the width of two image heads provided in a rotating drum larger than the width of the video track of a tape, comparing the intensity of FM image signals reproduced and detecting an error voltage. CONSTITUTION: A first image head 2 and a second image head 3 are mutually installed at 180 deg. azimuth to a rotating head drum 1, the width D of heads 2 and 3 are made to be about 1.5 times larger than the width P of the video track. The second head 3 is positioned so that its lower end part conforms to the reference surface 4, and the first head 2 is positioned so that its upper end part is by the width P of the track higher than the reference surface 4. When the video track is correctly tracked, reproducing FM image signals of the same intensity are obtained in both heads 2 and 3. If the speed of the tape is fast, image signals of the head 2 become smaller than those of the head 3, while if the same is slow, image signals of the head 2 become larger. Therefore, if the speed of the tape is controlled so that image signals become same, tracking is correctly performed.

Abstract: PROBLEM TO BE SOLVED: To obtain a battery having large discharge capacity per electrode active material weight, interchangeability with an aqueous solution primary battery, and usefulness in industry by molding a sulfur compound of FeS, Fe2 S3 , and iron in pellet form having an indefinite composition ratio to use the sulfur compound for positive or negative electrodes. SOLUTION: The sulfur compound of iron, expressed in a general formula Fe1-x S (0<x<1), is used for a positive electrode, and a lithium storable material, containing lithium having oxidation-reduction potential lower than that of the sulfur compound of iron, is used for a negative electrode. When the lithium storable material is used for the negative electrode, a lithium releasing material, containing high-oxidation reduction potential lithium, is used for the positive electrode opposite to the case of the negative electrode. For instance, material obtained by mixing FeS and a conductive agent to pressure-mold the mixture onto a mesh, and then decompress and dry the mixture, and lithium pieces are used as the positive and the negative electrodes 3 and 5 respectively, to constitute a battery by impregnating an electrolyte into a separator 4.  At that time, the positive electrode 3 is heat treated for 12 hours at 110-220 deg.C in atmospheric air, thereby obtaining high capacity having a discharge capacity of 420-450mAh per positive electrode active material weight.

Title: Modulator and demodulator
Inventor: KAMATA KOUZOU
IPC: H03C1/48
Filed: 1981-01-14
Abstract: PURPOSE:To obtain a modulator/demodulator which can work in a wide range of frequency, by applying the magnetic flux obtained from a signal current or a modulated wave current to a Hall device and using a carrier current for the control current of the Hall device. CONSTITUTION:A magnetic flux corresponding to the signal waves P which are supplied to elements 5 and 6 is produced at a coil 10 to be applied to the Hall device 10 in the form of the magnetic flux density B. At the same time, a carrier wave C is applied to the device 10 as a control current. Thus the amplitude is modulated, and the upper and lower side band waves C+P and C-P are produced at terminals 7 and 8. In such way, a DC is applied when necessary in the form of a wave P to perform the transmission of the carrier wave as well as the phase modulation of the carrier wave with inversion of the application polarity of the DC. Then the demodulation is possible by applying both waves C+P and C-P or either one of these two waves to the terminals 5 and 6. Thus the wave P plus high frequency components 2C+P and 2C-P or either one of them is produced at the terminals 7 and 8. Thus the wave P can be extracted.

Abstract: PURPOSE:To effectively utilize the total filtration surface and to prevent contaminants from easily remaining in a prefiltration chamber after washing by giving turning flow to water before filtration along the inner peripheral surface of the prefiltration chamber and also internally installing a filter with the axial center of its circumferential surface being eccentric to the center of turning of the water before filtration. CONSTITUTION:Water before filtration is caused to flow in a prefiltration chamber 3 in a state of being given turning flow along the inner peripheral surface of the prefiltration chamber 3 and also a filter 2 whose peripheral surface 15 on the prefiltration chamber side is formed into a circumferential surface is internally installed with the axial center X of the circumferential surface being eccentric to the center of turning Y of the water before filtration. Consequently, the variation in the distribution of the inflow quantity of the water before filtration to the filter 2 along the peripheral surface 15 on the prefiltration chamber side is reduced to separate contaminants over the total filtration surface of the filter 2. The sectional area of a passage where the water before filtration is given turning flow is changed along the turning direction to generate the turbulent flow, allowing the contaminants to be given diffusional flow, thus reducing the accumulation of contaminants on the bottom part, etc., of the prefiltration chamber 3.

Title: Noise reduction circuit
Inventor: AKAGIRI KENZO
IPC: G11B20/06
Filed: 1989-01-12
Abstract: PURPOSE:To reduce noise modulation by governing the frequency characteristic of the whole of a circuit by a first LPF in case of an input signal in a low level and obtaining the frequency characteristic where the characteristic of a second LPF is added in accordance with the rise of the level. CONSTITUTION:When the level of the input signal is low, the gain of a voltage controlled amplifier 25 controlled by an HPF 29 and a control circuit 28 is small and the characteristic of a flat-pass circuit influentially appears. Consequently, the frequency characteristic of the whole of a decoder circuit 30 is determined by a first LPF 23. When the level of the input signal rises, the gain of the amplifier 25 is increased and the frequency characteristic of a second LPF 24 appears, and therefore, the frequency characteristic of the circuit 340 approximates the characteristic obtained by adding the characteristic of the LPF 24 to that of the LPF 23. Thus, the difference of response between the low band and the high band is a maximum of 20dB and great deemphasis is applied, and the degree of separation between middle and low bands and the high band is raised to reduce noise modulation.
