Patent JP-S5684052-A (JP)
Title: Automatic transmission-line switching system
Inventor: IFUKURO SADAO
IPC: H04B1/74
Filed: 1979-12-13
Abstract: PURPOSE:To prevent switching operation from being repeated when transmission lines are switched by monitoring the error rate of an in-use transmission line, by providing two threshold  values of the error rate to be changed over and by changing threshold values of the error rate  when it is changed over to a stand-by transmission line. CONSTITUTION:While an in-use transmission line is provided between transmitting terminal station 2a and receiving terminal station 4a, a stand-by transmission line is provided between transmitting terminal station 2b and receiving terminal station 4b and receiving terminal station 4a is provided with a method of measuring error rates of transmission lines. Firstly, the threshold value of the error rate is set to 10<-6> and if the error rate of the stand-by system reaches 10<-6> or more, a switching indication signal is sent to switch control part 6, which applies a switching control signal to switch parts 1 and 5 to change the in-use system over to the stand-by system. This switching control signal is applied to receiving terminal station 4a and the threshold value of the error rate is changed over to 10<-9> to measure the error rate of the monitoring pattern of the in-use system, but even if the error rate changes to about 10<-6>, the switching operation is not performed and when it decreases down to 10<-9> or less, the switching indication signal is sent to control part 6 to changes the stand-by system over to the in-use system.

Title: Two electrode latent arc welding method
Inventor: SUZUKI SHIGERU
IPC: B23K9/073
Filed: 1982-09-14
Abstract: PURPOSE:To prevent interference of an arc and turbulence of an arc between electrodes, and to raise a welding speed and a welding quality, by making a half-wave current being out of phase from a DC base current flow to each electrode of two electrode latent arc welding. CONSTITUTION:In case of welding, a half-wave current (a) flows through a diode 18, an electrode 11, a base metal 10 and a diode 17 from an electric power source transformer 14. Also, a half-wave current (b) flows through a diode 19, an electrode 12, the base metal 10 and a diode 16 from the electric power source transformer 14. In this case, a current being out of phase flows to each electrode 11, 12, therefore, arc interference between two electrodes can be reduced, and also a welding speed can be increased. Also, it is considered that an arc becomes unstable at the time of switching the phase, due to a fact that half-wave electrodes (a), (b) are used, but since a direct current is made to flow simultaneously, turbulence of the arc can be prevented, as well.

Abstract: PURPOSE: To prevent loss from breakage of joints due to external stress by composing elastic washers made of synthetic resin for use in coupling of rectangular structure in the longitudinal direction having an equivalent yield stress and lower compression modulus of elasticity compared with steel stock. CONSTITUTION: A rectangular structure is composed by linking the space of unit members 1, 1 with longitudinal coupling 2 and with coupling plates 3 using a bolt 4, an elastic washer 7 and a nut 6. In this instance as synthetic resin composing the washer 7, material having more than 700 kg/cm<2> in yield stress and 0.02-0.05 as the ratio of yield stress to the compression modulus of elasticity is used. Thereby, against the external stress applied to the coupling, the washer will absorb the stress and as the deformation value is small, no positional shift occurs; thus, any damage in the coupling is prevented.

Abstract: PURPOSE:To permit local working of glass members as well with a sharp heat source by coating frit glass to the intended joint part of the glass member to be joined to wet said part with the frit glass then heating the glass member to form an intermediate glass layer and successively welding the same to the mating member. CONSTITUTION:A valve 1 and a mount 2 are first set to the head of a sealing machine and while the head is rotated, the intended joint part 1a is heated by a gas burner 10 in the case of sealing the valve and mount of a fluorescent lamp as the members to be joined. The aperture end 1a of the valve 1 and the circumferential edge end of a flared part 3 are softened by such heating; at the same time, the frit glass 8 preliminarily coated to the end 1a is melted to wet the joint surface. As a result, adhesive power acts to reduce the spacing between the joint surfaces and to form the intermediate glass layer 8a by joining the joint surfaces with the extremely with solder glass. Such layer is cooled and solidified by which the sealing is completed. The generation of the work strains in the glass is thereby decreased and the local working is made possible in the same manner as in welding of metals without the need for annealing.
