Abstract: PROBLEM TO BE SOLVED: To prevent the increase in conductor resistance and waviness of a conductor core by setting a stranding pitch of a reversing part of an S-stranded part and a Z-stranded part to be shorter than a stranding pitch of an intermediate part sandwiched by the reversing part. SOLUTION: An S-stranded part 6 and a Z-standed part 7 are alternately and repeatedly twisted, and a stranding pitch of a reversing part 2 is set shorter than a stranding pitch of an intermediate part 3 which is sandwiched by the reversing part 2. Stranding pitches P4 and P6 shortened by the reversing part 2 are adjusted, by lengthening stranding pitches P5 and P7 of the intermediate part 3, and an average stranding pitch of the entire SZ stranded cable 1 is formed equal to a pitch of a unidirectional stranded cable, and a conductor core length is set equal to the unidirectional stranded cable, and conductor resistance does not increase. Since the pitches P4 and P6 are shortened, a conductor core 8 is densely arranged in the reversing part 2, and even if the SZ stranded cable 1 is twisted around, the conductor core does not become wavy.  Therefore, a telecommunication cable having an outside diameter not less than 10 mm can be realized by the SZ stranded cable 1, and therefore, it can be quickly manufactured by an SZ stranding machine.

Abstract: PROBLEM TO BE SOLVED: To improve an occupying rate at coil winding, and make it suitable for a small DC-DC converter choke coil by alternately laminating a insulated fiat stranded wire having a specific conductor thickness on an odd number layer and a fiat bare stranded wire having a specific thickness on an even number layer by specific layers, and forming a laminated insulating coating film and/or a fusible coating film outside. SOLUTION: Both conductor thicknesses of a insulated fiat stranded wire 3 and a flat bare stranded wire 1 having a stranded wire insulating coating film 2 on a conductor 1' such as an annealed copper wire, are set to 0.2 to 0.1 mm, and the laminating number is set to an odd number of 3 to 21, and both ends of a laminated body become an insulated stranded wire 3. Therefore, it is easily manufactured, and is suitable for size reduction, and insulation is not bad. It is better to set a conductor width to 0.4 to 3.0 mm. An insulation/coating film and/or a fusible coating film are arranged as an outside laminated coating film of the laminated body.  When this electric wire is wound into a coil, the conductor surface area of the same cross-section area increases, and a loss of a high frequency reduces, and a outside coil diametrical dimension reduces, and the total length of the electric wire is shortened, and a loss of a direct current is reduced.

Title: Hot water supplier with bathwater heater
Inventor: ISHIHARA TOSHIAKI
IPC: F24D17/00
Filed: 1988-11-09
Abstract: PURPOSE:To prevent the noises of vortexes and also damage of a channel due to freezing by providing a directional control valve at a higher position than a cistern and by providing a channel connected at one end with the directional control valve and having the other end open under water in the cistern. CONSTITUTION:Hot water in a cistern 6 is taken into a channel 9, which is open downward, passed through a directional control valve 10 and a pump 11, and supplied to a bathtub 12. When the bathwater in the bathtub 12 is heated, the bathwater drawn from the bathtub 12 is heated by a bathwater heat exchanger 3, passed through the directional control valve 10 and the pump 11, and returned to the bathtub 12. The cistern 6 is placed lower than the directional control valve 10. Since the channel 9 is open downward, no vortexes are made when the water in the cistern 6 is sucked by the pump 11 and hence noises due to vortexes are prevented. The downward opening of the channel 9 serves to prevent freezing damage to the channel 9, because this channel 9 can be made free of water by opening a drain cock 8.

Abstract: PURPOSE: To eliminate the need of a resistor and a control circuit for processing the energy by normally setting carriers for three phases in-phase and switching them to three-phase at the time of braking thereby increasing the current ripples of the carrier frequency component. CONSTITUTION: A PWM inverter comprises carrier oscillators 2, 3 for oscillating signals having phase lags of 120 deg. and 240 deg. behind the oscillating position of 0⊥ of a carrier generator 1 generating a reference carrier signal. At the time of acceleration or steady operation, switches 7, 8 are turned to side A in order to modulate three phases with a reference carrier. At the time of deceleration, the switches 7, 8 are turned to side B in order to modulate phases V and W with a carrier signal having phase lags of 120 deg. and 240 deg. behind phase U. Consequently, the three-phase voltage of carrier frequency component is fed to comparators 4, 5, 6 and a motor is applied with an output signal operated by comparing voltage command signals eu , ev , ew with three triangular carrier signals ec having different phases.  This method can eliminate the need of a resistor to be inserted into a DC bus and a control circuit therefor.
