Title: Clock reproducing circuit for magnetic disk device
Inventor: SHIMODA KANEYASU
IPC: G11B20/14
Filed: 1992-09-01
Abstract: PURPOSE:To accurately reproduce clocks without generating the pseudo pull-in of the clocks by monitoring the level of sampled reproducing signals and interrupting the circuit of a clock reproducing system when the levels of sampling signals and the delay signals are respectively zero level. CONSTITUTION:The sampling signal Yn and a signal Yn-1 delayed for one symbol from the sampling signal are compared at a comparator 24 and when it is discriminated that the both signals are turned to the zero level simultaneously, an opening/closing switch 80 provided between a subtractor 67 and a loop filter 68 is opened by a zero level monitoring circuit 10. Thus, the input of a phase difference Zn detected at the subtractor 67 to the loop filter 68 is interrupted, a voltage controlled oscillator 69 is self-driven and there is no possibility of the clock being reproduced by pseudo pull-in. Then, when an oscillation frequency arrives near a normal clock frequency, the levels of the sampling signal Yn and the delay signal Yn-1 are not the zero level so that the switch 80 is closed by the circuit 10 and the clock is pulled in.

Abstract: PURPOSE:To attain the reduction in resistance and the flattening of the title device using polycrystalline Si, by a method wherein phosphorus at his concentration is diffused by a silica film containing phosphorus in polycrystalline Si. CONSTITUTION:An Si oxide film 102 is formed on a P type Si substrate 101, and a gate film 103 made of thin Si oxide film is formed in the active region. A polycrystalline Si layer is formed by deposition thereon, thus forming a wiring electrode 104. Next, to reduce the electrical resistance of the wiring electrode 104, a liquid silicate glass 105 containing phosphorus is formed by spin coating so as to obtain a required thickness at the flat part. At this time, the silicate glass accumulates thick at the step part. In this state, heat treatment is carried out at 800 deg.C or more. Further, an insulation film 106 is formed. Since the silica film 105 flattens the step part, glass flow which has been performed as flattening treatment is unnecessitated. Finally, contact holes are formed, and an Al electrode wiring 107 is formed.

Filed: 1983-12-13
Abstract: PURPOSE:To make accurate starting by monitoring directly electromotive force of a solar light electric power generator that in used a power supply of an electric power converter and starting the electric power converter according to the detected level. CONSTITUTION:When electromotive force of the generator 11 increases, the current that flows in a current detector 41 increases, and the output current is detected 42. When the value arrives at a value sufficient to start the electric power converter 13, an output signal 421 operates. Consequently, gates of switching elements 321, 323 stop and switching elements 323, 324 having self arc extinguish function are disconnected to stop an inverter circuit 32. Then, the current so far flowing in a DC reactor flows through a reflux diode 33, and therefore, the generation of excess voltage due to breaking action of the circuit 32 is suppressed. Subsequently, a switch 15 is turned on, and gate signals 431 are fed to switching elements 321-324 to make the circuit 32 a separately excited inverter to use as a specified main circuit.

Abstract: PROBLEM TO BE SOLVED: To make it unnecessary to hold a beverage can at a high temperature for a long time and to make it possible to instantaneously heat the can by heating a beverage can set up on a loading part by a high frequency magnetic field generated from a heating coil. SOLUTION: A user sets up a beverage can 1 taken out from a refrigerator e.g. on a loading part 2 and depresses a start switch on an operation part 6. A signal from the switch is transmitted to a control circuit 5, which drives a high frequency power supply device 4 for supplying high frequency power to a heating coil 3 to supply the high frequency power to the coil 3. Simultaneously the circuit 5 supplies power also to a cooling fan 7 to cool the coil 3. When the high frequency power is supplied from the device 4, the coil 3 generates a high frequency magnetic field. The beverage can 1 put on the loading part 2 is crossed with the high frequency magnetic field and instantaneously heated by induction heat. Then the circuit 5 stops the drive of the device 7. Since the beverage can 1 can be instantaneously heated, it is unnecessary to hold the can 1 at a high temperature state.

Filed: 1984-11-09
Abstract: PURPOSE:To detect a periphery position of a screen automatically with high precision by picking up peripheries of a displaying screen of a picture tube and removing errors, due to both phosphor arrangement and color picture tube structure, with image-processing of the obtained picking-up output signal. CONSTITUTION:Measuring patterns are displayed, with a pattern generating circuit 8, all over the displaying surface 1a of a color picture tube 1, and each area, which contains a periphery of the screen, is picked up, with an ITV camera being moved along each periphery of the displaying surface. Then, while the picking-up output signal is binary-coded through an interface circuit 5 and memorized in an image memory 9, the width-phased signal of the convex part, which is based on phosphor arrangement, or corresponding to the convex part is obtained and memorized in an image memory 10. Both signals are added, and then enlargement-reduction processing is made by use of an enlargement circuit 13 and reduction circuit 14 to recognize the peripheral part of each area, with characteristic valuation of the picture tube being enforced on the basis of the computed value. Therefore measurement with high precision can be realized without eye judgment.

Title: Fixing and inverting device
Inventor: HIRASAWA JUNICHI
IPC: G03G15/20
Filed: 1984-11-09
Abstract: PURPOSE:To prevent paper from waving and curling on the whole and to obtain print paper of high quality by shaping and arranging a separation claw so that transfer paper discharged from a fixing device is fed in the tangential direction of the roller couple of the fixing device or below it. CONSTITUTION:The distance between the separation claw 7 and a guide 8 is made sufficiently short and paper becomes hard to wave and flap. The vertical width D of inverting guide members 11 and 12 is suppressed to about 3mm. Further, the separation claw is projected into a conveyance path so that paper is fed in the tangential direction of the roller couple or below it. Consequently, the transfer paper 6 is sent in the tangential direction of the roller couple or below the tangent by the separation claw forcibly to some extent right after passing between a heat roller 3 and a pressure roller 4. Consequently, the transfer paper moves afterward by gravitation in the direction where it is guided forcibly.

Abstract: PURPOSE: To improve key operation on the keyboard on the piano by making the base end of a jump lever move toward a receiving structure when the jump lever is elevated and then come into contact with the structure. CONSTITUTION: A line, i.e., a cord 48 is tightened by clamping a screw 47, large downward pressure is applied to the end part 27a of a thrust balance lever to reduce the downward pressure of the end part 27a of the thrust balance lever applied to a right-angled part, i.e., a flange 53, and the friction when the end 26a of the jump lever begins to move laterally from its support position is always reduced. Then the end 26a of the jump lever starts its lateral movement after a swing lever 26 is moved up enough to bring the end 26c of the jump lever into contact with a receiver 36, and when the base end 15a of a key of the piano is further pressed downward, the swing lever 25 keeps on moving up. Consequently, the key operation on the keyboard is improved.
