Title: Mass flowmeter
Inventor: SUGIMOTO KOYATA
IPC: G01F1/84
Filed: 1989-03-31
Abstract: PURPOSE:To detect the abnormal vibration of a pipe, to prevent breakdown and to decrease erroneous measurements by detecting voltages which are generated in correspondence with the amplitudes of the vibrations of the pipes imparted by an exciting means, and comparing the voltage values. CONSTITUTION:Voltages which are generated with first and second exciting means are detected with a first absolute-value circuit 1 and a second absolute circuit 2. Thus the amplitudes of first and second pipes (sensor tubes) are detected. A threshold value is set with a threshold setting circuit 3 in correspondence with the detected signal of the first absolute value circuit 1. The threshold value is compared with the output signal of the second absolute value circuit 2 in a window comparator 4. When the amplitude is changed from the value at the normal time, the threshold value or the output detected signal of the second absolute value circuit 2 is changed. Abnormality is detected based on the relationship, and the vibration is stopped. Therefore, breakdown of the pipes can be prevented, and the reading of the erroneously measured value is eliminated.

Title: El lighting circuit
Inventor: IWATA KOZO
IPC: H05B44/00
Filed: 1989-03-31
Abstract: PURPOSE:To reduce loss in a switching element with no increase of electric power consumption by driving the power supply switching element through a transistor which detects the current polarity of a series resonance circuit composed of the inductance of a choke coil and of the electrostatic capacity of an EL. CONSTITUTION:The current polarity of a series oscillation circuit composed of the inductance of a choke coil CH and of the electrostatic capacity CEL of a distributed type EL in series, is detected by current polarity detecting transistors(TR) Q2 and Q4 so that TRQ2 or Q4 is turned on in response to the current polarity. This causes TRQ1 or Q2 of a polarity change-over switching element for a corresponding power supply to be applied, to be driven so as to be turned on so that current with required polarity is applied. By this constitution which does not employ any blocking oscillation system, but is capable of detecting current polarity with high accuracy without making a secondary coil large in size, loss in the switching element can be reduced with no increase of electric power consumption.

Title: Input circuit with termination resistor
Inventor: YAMADA HIROYUKI
IPC: H03K19/0952
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to receive an input signal without reflection even when the amplitude of the input signal is high. SOLUTION: A depletion FET 10 is in operation in a linear region when the voltage at an input terminal IN2 does not exceed a barrier voltage in a Shottky forward direction of an enhancement FET 12 to provide a desired termination resistance with respect to an input signal. Furthermore, the FET 10 is in operation in a saturation region when the voltage at the terminal IN2 does not exceed the barrier voltage of the FET 12. A resistor 11 has a resistance to produce a desired termination resistance together with the resistance of the FET 10 when the FET 10 is in operation in the saturation region.  Even when an input voltage at the terminal IN2 gets higher and a Schottky forward current Is flows to the FET 12, the input signal impedance when viewing the terminal IN2 is a desired termination resistance depending on the resistance of the FET 10 and the resistor 11 and no reflection of the input signal is caused.

Title: Suppressing method for convection behind molten metal in high speed arc welding
Inventor: NOMURA HIROICHI
IPC: B23K9/08
Filed: 1981-06-01
Abstract: PURPOSE:To suppress titled convection and to improve the upper speed boundary high speed welding by locating an electromagnet which has a coil of a cable connected from an earthing plate to an earth point always below the molten pool and generating electromagnetic force in a welding advance direction. CONSTITUTION:In high speed arc welding which progresses welding while generating arcs by flowing earth current from a welding electrode 12 to metallic base materials 11 to be welded, an earthing plate 13 is kept located always below the electrode 12. Therefore, the earth current flows always in the direction right under the molten pool A as shown by solid arrows, and flows through the electrode 12  the materials 11  the plate 13  a cable 17  an earth terminal, thereby generating the magnetic field penetrating therough the materials 11 and the pool A between both magnetic electrodes of an iron core 14. The electromagnetic force in the same direction as the welding advance direction is generated as shown by blanked arrows by said magnetic field, whereby the plasma flow is suppressed and the convection behind the molten metal is suppressed well. Therefore, in spite of an increase in the upper speed boundary of the high speed welding, the possibility of undercutting is eliminated.
