IPC: B23K20/00
Filed: 1986-11-20
Abstract: PURPOSE:To form an HIP processed joining material with sufficient strength by performing the diffusion joining of materials to be joined to each other so that the void remains in a vacuum at the time of carrying out the pre-treatment to prevent gas from penetrating in the joining surface after the materials to be welded are abutted on each other. CONSTITUTION:After the joining surface 17c of the material 17a and 17b to be joined is degreased and subjected to the ultrasonic cleaning, the materials to be joined are set on the mounting base 14 of the materials to be joined in a chamber 11 in a superposed state. After the inside of the chamber 11 is exhausted by a vacuum pump 12, inert gas is introduced and filled therein from a gas introducing device 13 and further, the degree of vacuum is raised and the inside of the chamber 11 is to abt. 10<-4>-10<-5> torr. Then, the pressurizing force is applied to the joining surface 17c by a pressure device 16 and the surface 17c is heated by a heating system 18. The diffusion takes places on the joining surface 17c where there was a gap and the joining surface where the void remains is formed and the inside of the void also becomes vacuum by carrying out the pre-treatment in this way. In this way, the tack-joined materials 17a and 17b to be joined are moved in a pressure vessel and subjected to the HIP processing and joined. In this way, the joining materials with the sufficient strength is formed.

Title: Electric discharge machining device
Inventor: ARAYA SHIZUO
IPC: B23H1/02
Filed: 1987-11-02
Abstract: PURPOSE:To reduce electrode consumption and generation of heat in a device as well as power consumption by increasing rising time for a working current pulse with inductance, and converting the stored energy into DC power via a transformer. CONSTITUTION:Primary winding of a transformer 10 is connected to a working power source 3 as inductance, and rising time for a working current pulse by a pulse generating circuit 4 and a switching element 5 is made lager. An energy differential portion with a square wave by this enlargement shifts to the secondary side of the transformer 10 within each period of the working pulse, and stored energy of the inductance is not left behind at the primary side, thus the next rising wave is formed into the same one. On the other hand, energy shifted to the secondary side is turned to DC power by rectifier circuits 11-14, checking generation of heat in a current limit resistor 6 via a cooling device 15. Thus, electrode consumption and the generation of heat in a device can be smaller and simultaneously watt consumption in a power source can be made smaller as well.

Filed: 1991-10-24
Abstract: PURPOSE:To uniformize the excitation of a radiation element over a broad band by extending plural microstrip line feeders radially from a center feeding point, branching the feeders in parallel toward the circumference resulting in increasing number of the feeders thereby reducing the length of the feeders. CONSTITUTION:Strip line feeders 1, 3, 5, 8, 10 with a narrow width and strip line feeders 2, 4, 9, 11 with a wide width at an interval of 1/2 wavelength are installed. Then microstrip antenna arrays 14, 15 whose radiation is set in response to the difference from the width of the feeders are connected in parallel as two branches from the feeders' side at a phase difference of 180 deg. with a deviation of 1/2 wavelength. Thus, the difference from the line width of each radiation unit is increased as the point is remoter than the feeding side. Then the travelling wave series feeding system is adopted and the feeders are arranged side by side at a phase difference of 180 deg. so that the narrow width feeder part is opposite to the wide width feeder part. As a result, the length of the feeders is reduced, the spurious radiation of the narrow width feeders is suppressed and the radiation element is uniformly excited in the direction of the feeding end.

Title: Balun circuit
Inventor: SUGIURA ATSUO
IPC: H01F37/00
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To reduce the attenuation of signals in a normal mode and to increase the attenuation of noises in a common mode by preparing the auxiliary coils to secure the coincidence of resonance points between both modes. SOLUTION: In a normal mode, the floating inductance Ls is added in addition to the resonance inductance L. However, no inductance Ls is added in a common mode, and accordingly the resonance frequency is increased. Thereby, the auxiliary coils 2a and 2b are placed in series with to respect inductors L1 and L2. The coils 2a and 2b have the bifilar windings, for example, and each of them has inductance equivalent to the inductance Ls. In a common mode, the currents flow in the same direction to both coils 2a and 2b to secure the functions of inductors. In a normal mode, however, the currents which are reverse to each other flow to the coils 2a and 2b so that no inductor functions is secured. Thus, the coincidence of resonance points is secured between both modes.
