Title: Reception circuit for ultrasonic diagnostic device
Inventor: NAKAO KENICHI
IPC: A61B8/00
Filed: 1994-06-10
Abstract: PURPOSE:To provide an ultrasonic diagnostic device having wide band of a reception signal and high S/N. CONSTITUTION:A tuning circuit is constituted of a capacitance component C interposed between a vibrator 10 and a preamplifier 18 and a coil L1, and the coil L1 is always inserted when an ultrasonic wave is received. The impedance of the preamplifier 18 to amplify the reception signal is set at a sufficiently low value. A diode which disconnects the coil L1 from the circuit by performing a turning off operation by a transmission signal is connected in series to the coil L1. In this way, a resonance function for the reception signal can be reduced, and the reception signal having wide band can be obtained, and the position resolution of the reception signal required in a mode B is not lowered. While, since a noise level can be reduced by a function to cancel the capacitance component of a cable 12, etc., by the insertion of a coil, high S/N can be obtained.

Title: Oscillator
Inventor: HAYAKAWA TATSUO
IPC: H03K3/0231
Filed: 1980-09-18
Abstract: PURPOSE:To make a titled oscillator stable against temperature and to avoid error  in oscillating period, by using the coupling circuit of an emitter follower of both  PNP and NPN transistors (TRs) as a clamp for a hysteresis comparator oscillator. CONSTITUTION:Expressing resistance values of resistors 19, 20 as R19, R20, a clamp voltage VINOT of an inverting input terminal IIN of a comparator 29 is shown  in Equation I, where VBE21, VBE23 are base-to-emitter voltages of NPN TR21 and  PNP TR23. The 1st terms of Equation I is independently of temperature and the  temperature characteristics of the VBE in the 2nd and 3rd terms are canceled with each other. Thus, the voltage VINOT is very stable against temperature and a clamp  type oscillator having stable temperature characteristics can be achieved. When a  switch 18 is closed, since the base of the TR21 is lifted up to the power supply voltage, the potential of the emitter of the TR21 is pulled up, the TR23 which is clamped turns off and oscillation is started. In this case, the time error in the 1st  period is not caused entirely.

Title: Input signal circuit
Inventor: ISHIKAWA MAKOTO
IPC: G05B19/05
Filed: 1989-05-23
Abstract: PURPOSE:To improve the economy of a slave station with small input point number by retarding a gate pulse sequentially, converting a signal from a sensor or a switch or the like into a pulse signal sequentially and supplying the pulse to a common line. CONSTITUTION:When a pulse signal is sent to a gate pulse line of modules M1-M5, the pulse is sequentially retarded by changeover delay circuits Z1-Z8. Then a positive pulse or a negative pulse is sent to a common signal line L in response to the on/off of a pushbutton switch 2 such as various switch or sensor, a changeover switch 3, relay contacts 4, 5, a microswitch 6 and a photoelectric sensor 7. Thus, the input signal circuit is simplified and wiring and space to a slave station with a small input point number are saved and the economical effect is improved.

Title: Pulse arc welding machine
Inventor: MOCHIGURI SHIGEO
IPC: B23K9/06
Filed: 1980-09-18
Abstract: PURPOSE: To eliminate the generation of spatters and to perform good welding by connecting a by-passing circuit in parallel to the reactor of a pulse electric power source, and allowing the electric current to fall right after the globule transfer to base metals.  
     CONSTITUTION: At the fall of pulse electric current, the voltage across a reactor 82 is higher at the point Q than at the point P. Hence, if a trigger signal is fed to a by-pass circuit 13 by driving a trigger circuit 14 upon the final fall of the individual pulses from a pulse electric power source 12, the by-pass circuit 13 conducts. Hence, the energy accumulated in the reactor 82 is released to the circuit 13, and only the base current flows to an arc 4. As a result, the finl fall of the individual pulses of the welding current waveform goes sharp. Hence, no excess current flows right after the transfer to globule, and the spatters generated considerably in the fall part of the pulses are eliminated.

Title: Process monitor controller
Inventor: MURAOKA NOBUYUKI
IPC: G05B23/02
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To deliberately execute the parameter adjustment work of a process. SOLUTION: The process monitor controller stores the subsequent fluctuation of a specified process in a process data storage means 3 as process data at a prescribed period whenever a parameter setting value is changed at the time of executing the detection work of an optimum value while the prescribed control parameter setting value is changed. For changing the parameter setting value for several times and detecting the optimum value from the situation of the fluctuation of process data in respective cases, the change time of the parameter setting value at respective times is set to be start time from the process data storage means 3 with the change time of the parameter setting value for respective times as keys.  Plural groups of process data whose collection time differ are read and plural time fluctuation graphs by setting change time as a common condition to be start time is compared and displayed in a graph display means 9. Thus, the optimum value of the parameter is decided from the situation of the time fluctuation of the plural displayed graphs.

Title: Induction motor-type electric rolling stock controller
Inventor: NOZAKI YOSHIO
IPC: B60L7/22
Filed: 1986-06-06
Abstract: PURPOSE:To improve a control performance of dynamic braking by controlling an energy consumed by a resistor with a specific resistance value inserted in a DC side. CONSTITUTION:In power running, a line breaker 3 is closed and a three-phase AC power with variable voltage and frequency is supplied from an inverter 10 to an induction motor 11. In this case, a slip frequency fs is added to an output frequency fr of pulse generator 12 to output an inverter frequency finv. In regenerative braking, the slip frequency fs is subtracted from a rotor frequency fr to output the inverter frequency finv. When there is no regenerative load on an electric overhead line side, the line breaker 3 is opened and a line breaker 7 is inputted while rotational energy is consumed by a brake resistance 8. At that time, the inverter 10 is controlled so that a power consumption of the brake resistance 8 is proportional to velocity.

Title: Package grinding device for semiconductor apparatus
Inventor: ASAI SHIGEMI
IPC: B24B41/06
Filed: 1986-06-04
Abstract: PURPOSE:To enable obtaining the ground surface of high precision at high efficiency by clamping both sides of a base with each one clamp for package positioning and pressing, and applying the constitution wherein vertical and horizontal vectors appear on the claw of the pressing clamp. CONSTITUTION:A clamping claw 9 is so fixed with a screw 11 as to be in contact with the upper surface 4c of a package fixing jig 4 and the side 4d thereof. Then, when another clamping claw 10 is gradually tightened with another screw 12 in such a way that a base 1 is placed on the fixing jig 4 and the side 1c of the base 1 comes in contact with the edge of another claw 9, the claw 10 is tightened and fixed, while pressing the side 1d of the base 1 in an 'E' direction with the edge 10a thereof about an edge 10b as a support point. It follows, therefore, that the edge 10a of the claw 10 is pressing the side 1d of the base 1 by a force f'0, thereby causing a horizontal pressing vector f2 for fixing the package in a horizontal direction and a vertical pressing vector f1 for fixing the package in a vertical direction (or for preventing the floating of the package). As a result, the package does not float during a grinding process, thereby ensuring high-precision grinding at high efficiency.
