Title: Low melting point ag solder
Inventor: WATANABE OSAMU
IPC: C22C13/00
Filed: 1988-12-29
Abstract: PURPOSE:To improve the mechanical strength of the solder itself by consisting the solder of specific weight ratios of Ag and Sn as its basic components and adding >=1 kinds among Cu, In and Ga thereto. CONSTITUTION:The low melting point Ag solder is composed by adding, by weight, 10 to 30% Ag, 70 to 90% Sn, and further 0.05 to 1% >=1 kinds among Cu, In and Ga thereto. The m. p. of the solder is, therefore, lowered by using the Ag-Sn of the eutectic type alloy as the basic components and the corrosion resistance and electrical and thermal conductive characteristics are improved by the presence of the Ag. Further, the mechanical strength of the solder itself is improved by the presence of >=1 kinds among the Cu, In and Ga.

Title: Constant current power supply
Inventor: UDA KOJI
IPC: H02M7/48
Filed: 1999-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a constant current power supply capable of supplying a load with a sine wave current and switching to a back-up power supply if a power failure occurs to a commercial AC power source. SOLUTION: A DC power supply 2 formed by converting the AC voltage of a commercial power source 18 into DC is connected to a back-up power supply 16 capable of supplying the same DC voltage with that of the DC power supply 2 arranged parallel to the DC power supply 2. An inverter circuit 3 is connected to the DC power supply normally and to the back-up power supply 16 in the power failure of the commercial AC power supply 18. Thus, a control circuit 8 can control loads 6,..., 6 continuously with the constant current by varying the 'on-off' ratio of main switching elements Tr1 to Tr4 in compliance with the output current value detected by an output current value detecting circuit 7.

Title: Electronic keyboard instrument
Inventor: IWASHITA HIROMI
IPC: G10H1/38
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide an electronic keyboard instrument capable of outputting musical tone signal in real time by the timbres and playing method intrinsic to a stringed instrument. SOLUTION: The key touch data of a keyboard 1 and the chord data of the stringed instrument are stored in correspondence in a chord data memory section 31. When the key touch data is inputted, a chord is assigned by referencing this chord data memory section 31. The fret position corresponding to the assigned chord is thereafter retrieved by a fret table 41 and the scale to make sound production is determined by the retrieved fret position and open string data. Sound production processing is then executed by preset playing operation patterns (for example, down stroke). Then, a player is able to produce the timbres of the chords intrinsic to the stringed instrument in real time by simple single hand manipulation.

Title: Low noise electric wire
Inventor: KONOSU KOZO
IPC: H01B5/10
Filed: 1989-12-27
Abstract: PURPOSE:To prevent both a wind noise and a corona noise from occurring, by closing a groove at its opening face with a wire material, forming a water passage between the groove and the wire material and projecting the wire material from the outer peripheral surface of the outmost layer strand wire by a proper height. CONSTITUTION:An outmost layer strand wire 1 is formed by stranding many segment strands 2 having a sectorial cross section, each of which strands 2 has a U shape cross section groove 3 engraved on its outer surface in the longitudinal direction. The groove 3 is closed at its opening face with a wire material 4 having a round cross section, while a water passage 5 is kept formed between the groove 3 and the wire material 4. The wire material 4 is projected from the outer peripheral surface of the outmost layer strand wire 1 by a proper height H so that the projected part of height H of the wire material 4 becomes a spiral projection along the strand pitch of the outer peripheral surface of the outmost layer strand wires 1. This prevents a Kalman eddy and then a wind noise from occurring, while rain water flows into the water passage 5 so that water drops are not allowed to drop from plural places, preventing a corona noise from occurring.

Filed: 1989-12-26
Abstract: PURPOSE:To promote the mixing of a vaporized gas and primary air by forming a mixing chamber of a lower intermediate cylindrical mixing section and an upper square pole-shaped flow regulating chamber. CONSTITUTION:A mixing chamber 29 is formed by a lower intermediate cylindrical mixing section 30 and an upper square pole-shaped flow regulating chamber 31, and a burner head 32 is installed at the upper end of the mixing chamber 29. Vaporizing air having flowed into a carbureter 25 from an vaporizing-air inlet 24 of air sent from a combustion blower 33 carries a vaporized gas generated in the carbureter 25 to the center of the mixing section 30. Primary air having passed through a primary-air path 26 of air sent from the combustion blower 33 flows in along the inner circumferential surface of the mixing section. Primary air and the vaporized gas are ejected to the flow regulating section 31 while being sufficiently mixed owing to the narrow long-sized path of the mixing section 30. The sufficiently mixed pre-mixture is burnt together with secondary air by the burner head 32, thus improving burning characteristics.

Title: Network operating method
Inventor: KURISU HIROMITSU
IPC: G06Q50/28
Filed: 1991-12-20
Abstract: PURPOSE:To make an operating plan at a high speed in order to satisfy various operating conditions in a transport network where plural supply points are connected to plural consumption points. CONSTITUTION:Various conditions are set 11 for making a plan, and a distribution plan is calculated 12 in a fixed formula as a least cost flow rate problem. In this case, the least cost flow rate satisfies only the matter preserving conditions and the upper and lower limit levels of the pondage and the flow rate. Thus the least cost flow rate can be calculated at a high speed by a mathematical P1.80 method. However the least cost flow rate has a large time fluctuation of the flow rate and is inapplicable to the actual operation. In this respect, the solution is improved 13 with smoothing of the flow rate, etc., in order to satisfy various operating conditions. The plan value thus obtained is decided 15 by an operation planner. If the planner judges that the plan value is improper, the set conditions are varied and the same processing is repeated.
