IPC: H03M1/36
Filed: 1986-03-05
Abstract: PURPOSE:To attain the high speed A/D conversion with a simple circuit by converting an analog input voltage into plural stages of divided voltages and inputting the result in parallel with a gate circuit comprising TTL logic. CONSTITUTION:The plural stages of divided voltages by a resistance voltage division circuit 10 are inputted to TTL gate circuits 12A-12E in parallel. Then a digital signal of a prescribed bit number comprising '1'/'0' output is converted depending whether each voltage division voltage reaches an operating point decided by the threshold level of the gate circuits 12A-12E themselves. Thus, the speed of the A/D conversion becomes a high speed decided definitely by the operating speed of the gate circuits. Further, the circuit is simplified because the voltage division resistor circuit comprising plural resistors connected in series and the gate circuits of the number corresponding to bit number are enough for the purpose.

Title: Pulse width modulation signal generating circuit
Inventor: OGURI YUKIO
IPC: H03K7/08
Filed: 1990-02-28
Abstract: PURPOSE:To reduce the dispersion in a delay time and a pulse width by selecting a pulse generating period of a 2nd clock signal being a reference pulse to be a sufficiently shorter period than a prescribed delay time difference to be delayed. CONSTITUTION:A pulse number DELTAP of a 2nd clock signal corresponding to a time difference tauD is preset to a register 64. A computing element 66 adds a 2DELTAP twice the pulse number DELTAP set to the register 64 to a pulse number P represented by a control signal fed from a computer system 42 to calculate a 1st pulse number P1 (=P+2DELTAP). Since the pulse generating period PT2 of the clock signal CLK being a reference pulse is sufficiently shorter than a prescribed time difference tauD to be delayed, the dispersion in a delay time and a pulse width is decreased and transistors(TRs) 1, 2 being a couple of controlled elements are subject to switching control with high accuracy.

Filed: 1989-02-28
Abstract: PURPOSE:To prevent the noises which are produced when the control signals are outputted from plural ports in parallel with each other by providing plural delay circuits to delay the control signals to be applied to each port at different times and scattering the through current in terms of time. CONSTITUTION:The control signals 20 - 22 received from a CPU 3 activate the ports 13 - 15 in a normal mode and are inputted to one of both input terminals of each of OR gates 16 - 18. A control signal 23 activates the ports 13 - 15 in a test mode and is inputted to the other input terminal of the gate 18 and also to the other terminal of each of gates 17 and 16 via the delay circuits 30 and 31. Both circuits 30 and 31 are set at the prescribed delay times, and the control signals are delayed for each of ports 13 - 15 and supplied. Thus the output timings of ports 13 - 15 are delayed with each other to scatter the through currents and to suppress the peak value. As a result, the production of noises can be prevented on a line.

IPC: G11B5/147
Filed: 1984-03-16
Abstract: PURPOSE:To manufacture an excellent magnetic head which has a good output characteristic and does not produce any core and gap slippage even under a high-temperature high-humidity atmosphere, by forming the core half body of the magnetic head in such a way that magnetic films which have a high magnetic permeability and on which insulating layers are respectively formed are piled up and joined together by heating, and then, the core half body is welded to another with a low-melting point glass material. CONSTITUTION:Thin plates 1 of a ''Sendust'' material covered with an inorganic insulating layer are piled up and strongly joined with each other by pressing at a high-temperature 3 and 4. Then a winding groove 6 is formed in one block 5b thus formed and thin films are formed on surfaces 7a and 7b by sputtering. The core blocks 5a and 5b thus formed are then put together and welded to each other with a low-melting point glass material, and thus, a core block 8 is formed. The core block 8 is then sliced to the track width and a winding 10 is installed through the winding groove 6 to produce a magnetic head. Since the glass material put on the joining surface 7 has a low melting point and does not produce any core and gap slippage and the magnetic head is manufactured in a laminated structure, a highly reliable magnetic head which does not produce any output drops at low frequencies and has an accurate magnetic gap can be manufactured.

Abstract: PURPOSE:To visualize an MHD (Magnet-Hydro-Dynamic) effect by allowing an electric current to flow under the condition that a magnetic field words, decomposing water and allowing bubbles of hydrogen and oxygen to ascend. CONSTITUTION:An electrolytic water solution 2 of NaOH, etc. is put into a transparent case 1, and two pieces of electrodes 3, 4 are opposed to each other in the vertical direction. When a voltage is applied to the electrodes 3, 4 and a current is allowed to flow, oxygen or hydrogen is generated in accordance with whether the polarity of the electrode is positive or negative, and it becomes a thin line and ascends. When a magnetic field is applied thereto, the line is inclined. That is, the solution can be made simply since it will suffice that a small quantity of electrolyte of NaOH, etc. is added to water, and also, because of an electrolysis, as for a power source, a small battery is enough. In such a way, by using a simple method and device, an MHD effect (or Lorentz's force) can be visualized.
