Abstract: PURPOSE:To simplify the circuit constitition and to expand capture range and lock range by using the output of a servo control means to control the relative speed between a rotary head and a tape to a constant value at the high speed reproduction. CONSTITUTION:A data reproduced from a tape by a rotary head 1 is fed to a PLL circuit 5, a lock is extracted to extract the data, the result is fed to an envelope detection circuit 10 where the envelope is detected, the detected output is waveform-shaped by waveform shaping means 11, 12, and the output controls the lock state of the PLL circuit. That is, when the waveform shaping output is at a high level, the feedback loop of the PLL circuit is closed to cause the locking state and when at low level, the feedback loop of the PLL circuit is opened to cause the hold state. Further, a control voltage of a VCO 9 of the PLL circuit is fed to servo control means 13-20 as servo information to apply constant control so that the relative speed between the tape and head at the high speed reproduction is nearly equal to that at the normal reproduction.

Filed: 1983-05-27
Abstract: PURPOSE:To avoid the working interference among plural robots by providing the areas which cannot be executed simultaneously to a part of the control program of each robot and providing a control program to make said part of the control program perform the interference actions. CONSTITUTION:Plural flag registers 5, 6-(only a register 7 shown in the diagram) are provided between control parts 2 and 4 of robots 1 and 3 respectively. An output terminal 8 of the part 2 supplies input to an AND 16 through an input terminal 9 of the 7th register. The output of the AND16 is fed back to its own end terminal 10 and also supplied 19 with inversion to an AND17 of the other end. While the output of the AND17 of the other end side is supplied with inversion to the terminal 18 of the other side of the AND16. When either one of parts 2 and 4 registers a flag, the register of the other part is inhibited. Thus the robot work is permitted only at one side of the area related to the register 7 and inhibited at the other side. Thus the robots can perform their jobs with safety and without mutual interference.

Title: Rotation frequency detecting unit
Inventor: HOSAKA HIDEO
IPC: G01P3/488
Filed: 1979-07-23
Abstract: PURPOSE: To make it possible to obtain a high-precision output signal proportional to the number of rotations even in the range of a small number of rotations, by fitting plural electromagnetic pickups while shifting the phase for the pitch of teeth of the gear for rotation frequency detection.  
     CONSTITUTION: For example, three electromagnetic pickups 2 are provided near teeth of gear 1 fitted to the rotation shaft. These pickups 2 are fitted with the phase shifted for the pitch of teeth by Ψ and 2Ψ. Outputs of respective pickups 2 become differentiation signals through a waveform shaping equipment and a differentiating equipment and are led to an adder and are added. As a result, since the pulse signal for every one rotation of the rotation shaft can be increased three times, the number of rotations can be detected accurately even in the range of a low speed of the rotation shaft.

Filed: 1991-04-01
Abstract: PURPOSE:To obtain the dry toner having a excellent characteristic by adding water-soluble nigrosine into a water phase and subjecting a polymerizable monomer to a suspension polymn. in an aq. medium, thereby efficiently preventing the generated emulsion polymn. CONSTITUTION:The polymerizable monomer, coloring agents and charge control agent, etc., which are the essential components of the toner constituting an oil phase are prepd. as a dispersion and after a polymn. initiator is added and dissolved in the prepn. and thereafter, the suspension is dispersed and suspended in the water phase. A dispersion stabilizer consisting of a water-soluble high polymer, such as polyvinyl alcohol or hardly water-soluble inorg. powder, such as tricalcium phosphate and a surfactant, such as dodecyl sodium sulfate, and the water-soluble nigrosine as a polymn. inhibitor of the water phase are added to the water phase. The dispersed suspension is heated to polymerize the polymerizable monomer. The emulsion polymn. generated in the water phase is efficiently prevented in this way and the electric resistance, triboelectrostatic charge characteristic, weatherability, and flowability are improved. The toner with which the excellent image quality is obtainable is thus obtd.

Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To avoid the cracking from any places other than specified ones in the molding time, by polygonally shaping an epitaxial wafer by grinding the outer periphery of the wafer. SOLUTION: The first and second epitaxial layers 3A, 3B comprising AlGaAs are formed as a pn junction layers by liquid growing process on a semiconductor substrate 2 comprising GaAs, and then the outer periphery of the epitaxial layers 3A, 3B is contoured so that respective directions may correspond to the cleavage direction (110).

Filed: 1984-05-09
Abstract: PURPOSE:To obtain a molded product such as container with an excellent physical property by thermoforming of a thermoplastic sheet heating it as vertically stretched so as to give molecular arrays in a non-parallel state, almost parallel. CONSTITUTION:Polypropylene or the like is molded into a sheet. Then, when it is stretched above the softening point but below the melting temperature thereof, for example, at 130-160 deg.C, first and second rolls 5 and 6 are made smaller so that they will be brought closer to one another to check extreme reduction in the width of the sheet S. With such as arrangement, the aligned molecules P are controlled in the direction with the first roll 5 so as to be partly at an gentle angle to the longitudinal stretching direction X, not all parallel thereto with the second roll 6. This produces a sheet which contains molecular arrays in a non- parallel state, almost parallel in addition to those parallel to the longitudinal stretching direction X. This sheet is used to obtain a molding by vacuum forming or the like.
