Title: Synchronous machine and synchronous frequency converter
Inventor: HIRAMATSU ONORI
IPC: H02K47/20
Filed: 1991-03-01
Abstract: PURPOSE:To obtain a synchronous machine and a synchronous frequency converter in which electric phase difference angle can be regulated easily without requiring a rolling unit by providing a cylindrical rotor applied with a two-phase DC field winding thereby making the combined exciting field regulatable in the direction of rotary angle. CONSTITUTION:Upon finish of initial excitation control, a circuit breaker 4 is thrown in to link power systems A and B. A power control section 16 compares a command power with a detected power and produces a signal 8 corresponding to the difference. The signal 8 is fed to a two-axle controller 10 so that it is added to a signal 9 outputted from an initial excitation control circuit 8. Consequently, DC field windings of two phases in a synchronous generator 2 are excited with DC current and the combined exciting field rotates by an amount in the leading direction. Since the control signal 8 functions as a phase difference angle, the system functions as a variable frequency converter even if the ratio of frequency between the power systems A and B fluctuates slightly.

Then, the flow rate is calculated from the product of the found flow velocity and the sectional area of the piping 1 which is already known. Consequently, the disorder is detected by each sensor at a sufficiently high level to perform the correlation arithmetic accurately.

Title: Cream solder
Inventor: OGURA TOSHIAKI
IPC: B23K35/363
Filed: 1994-03-07
Abstract: PURPOSE:To obtain the cream solder capable of precision soldering of an infinitesimal part, having high printing/discharging characteristics and good solderability, having low sag at preheating by containing the substituted urea compound substituted by aromatic base and aliphatic base. CONSTITUTION:A substituted urea compound is substituted with over one piece of aromatic base and/or aliphatic base, a total number of carbon atoms of substituent is 4-50 pieces. This substituted urea compound is used about 1-20wt% of the total weight of flux. In the case that this kind of urea compound is blended in flux as a viscosity adjusting agent of a cream solder, by the interaction of the carbon chain of relatively long chain and the strong structural characteristic of urea bonding, a high melting point gel is formed, showing very large thickening. Accordingly, the cream solder, which uses the substituted urea for a thickener, does not impair the corrosion resistance and high dielectric strength, remarkably improves solderability, has low slump at preheating and is suitable for precision soldering.

CONSTITUTION:When a nozzle shaft 1 is lowered, leads L at a TAB device P are landed on electrodes 33. Then, cylinder rods 12 protrude; thermocompression-bonding makers at the right and the left are pressed to the right and left electrodes 33. Since the surface of a substrate 32 is tilted at a small angle theta, a base member 16 is turned and moved slightly to the direction of an arrow N around universal joints 15. Consequently, the rear surface of the thermocompression-bonding makers 17 is face-landed firmly on the leads L; all the leads L are pressed and bonded to the electrodes 33 by means of a uniform force. Thereby, even when the substrate is tilted, the leads L are face-pressed and bonded to the electrodes 33 by means of the uniform force and without any irregularity.
