Title: Driving control apparatus for brushless motor
Inventor: IMAMURA TOMOATSU
IPC: H02P6/06
Filed: 1988-09-13
Abstract: PURPOSE:To obtain an intended rotation speed in a simple circuit by starting a motor with an external clock signal which is outputted exponentially, switching the signal to a binary coded signal of a voltage from the FG pattern part of a printed board, and performing phase excitation. CONSTITUTION:When a timer 23 is energized by the command from a host control part 25, an exponential-function-frequency generator 21 generates an exponentially increasing signal. A motor 60 is driven with a motor driving circuit 86 through a multiplexer 22 and a sequence logic 24. The number of rotation is increased. After a specified time, the waveform of the output of an FG pattern generator 62 which is driven with the motor 60 is shaped with an wave shaping circuit 87, and a binary coded signal is obtained. The output of a crystal oscillator 81 undergoes frequency division 82, and a signal is obtained. The phase of said signal is compared with the phase of the binary coded signal in a phase comparator 83. The result is smoothed in a smoothing circuit 84. The obtained signal is inputted into the motor driving circuit 86. The exponential function frequency signal is changed into said signal. In this way, the intended rotation speed is obtained with a simple circuit constitution readily.

Title: Semiconductor integrated circuit
Inventor: TAMADA HARUO
IPC: H01L21/761
Filed: 1982-12-28
Abstract: PURPOSE:To eliminate an adverse effect due to noises generated in a feeder, and to prevent the variation of the potential of a semiconductor substrate by separately setting up the terminal of a supply feeder or the terminal of a feeder, through which ACs flow, and a terminal for setting the potential of the semiconductor substrate. CONSTITUTION:When a transistor TR4 represents another element and pulse voltage is applied to one part such as a base of the element, potential between an emitter of the transistor TR4 and a grounding terminal GND is varied by a voltage drop in a resistor R resulting from wirings in the circuit, bonding wires and the pins of a package, etc., and the variation of potential has an adverse effect on the voltage of the semiconductor substrate. Consequently, the grounding terminal 10 of the semiconductor substrate is set up separated from the electrode 11 of the transistor TR4 executing switching operation. It is preferable that these electrodes 10 and 11 are connected separately to the pins 12, 13 of the package, but an excellent result can be obtained even when they are connected together with one pin 13 of the package.

IPC: H03F3/45
Filed: 1990-08-29
Abstract: PURPOSE:To easily connect the circuit to a circuit separated from a power supply of the former circuit by connecting emitters of a couple of complementary transistors (TRs) in series and using bases of the TRs for input terminals of a differential amplifier circuit.

Title: Pool level sensing and automatic level control method for continuous metallic casting machine of twin belt
Inventor: TEIMONSHII DEII KAIZAA
IPC: B22D11/16
Filed: 1987-09-11
Abstract: In continuous metal-casting machines utilizing one or more thin flexible belts (UB,LB) as mold surfaces, a suitably placed thermal sensing probe (48 or 62) which contacts the reverse side of a casting belt (UB) results in enhanced control of molten-metal pool levels. An intermediate temperature is selected as the control point, at one location in the mold. If the pool of molten metal (M) rises above or falls below the optimum level, the sensing probe (48 or 62) will register a correspondingly increased or decreased temperature. The resulting electrical signals are processed by an electronic circuit. The result may be displayed for manual control of metal feed or machine speed, or a resulting control signal may be employed to control automatically the flow of molten metal (M) into the mold cavity or, alternatively, to control the speed of the casting belts (UB,LB) which convey metal through the casting machine.
