Filed: 1990-07-07
Abstract: PURPOSE:To perfectly prevent the jetting of a material from a gate and to prevent the generation of a pressure gradient so that the pressure applied to a filling material becomes uniform at any part by freely changing the space volume of a mold. CONSTITUTION:When a space 20 is filled with the material from a molding machine in such a state that proper oil pressure (determined by the filling pressure of the material) is continuously applied to a hydraulic cylinder 16 and the oil pressure reaches the pressure applied to a piston or more, components 15, 21 and the piston are retracted and the space 20 increases to objective volume to complete the filling with the material.

Title: Transmission system for ringing signal
Inventor: HASHIMOTO MAKOTO
IPC: H04M3/02
Filed: 1986-08-01
Abstract: PURPOSE:To evade the misdetection of a ring trip detecting circuit without providing any protecting circuit to the ring trip detecting circuit by setting the phase state at the start of ringing signal transmission to a specific phase state. CONSTITUTION:When a ringing signal is sent out to a telephone set 3, a switch 7 is operated through the operation of the AND circuit 8 and phase detecting circuit 9 of an exchange control part 1 and a ringing signal generating device 4 sends out a ringing signal which starts at a negative cycle to the telephone set 3. When a subscriber performs off-hook operation in response, a DC component which is superposed by the off-hook operation is detected by the ring trip detecting circuit 6 and the exchange control part 1 switches the switch 7 with the detection information, thereby connecting the telephone set 3 to an exchange network 2. Consequently, a telephone call becomes ready. Thus, the phase state of the ringing signal generating device 4 is monitored and the switch 7 is switched when a negative cycle is entered, so the ringing signal starts at the negative cycle without fail and misdetection is evaded.

Filed: 1986-08-01
Abstract: PURPOSE:To weld a thick steel pipe with high efficiency without any defect by continuously tacking the outer face of the groove specifying the route face length with a CO2 gas welding and performing a multielectrode submerged arc welding by specifying the heat input amount. CONSTITUTION:In the case of welding a thick steel pipe in 25-60mm the outer face of a groove is continuously tacked with a CO2 welding so as to cause no gap with the length l4 of a route face 6 being taken in 6min and 10mm max. The inner face is then subjected to the multielectrode one pass welding with >=900A preceding electrode current and 75-150KF/cm heat input amount. For the outer face welding, a multielectrode submerged arc welding is performed with the heat input amount of 75KJ/cm by taking a 1st electrode current at >=900A and a 2nd electrode and on 90-100% current thereof on the tacked bead. Consequently a burn-through is prevented, the welding efficiency of a thick steel pipe is rapidly improved and the welding without defects is enabled.

Abstract: PURPOSE:To make it possible to draw out ions continuously and stably for a long time by using a sputtering utilizing the microwave plasma generated by the electron cyclotron resonance. CONSTITUTION:The plasma is generated and heated by the electron cyclotron resonance (ECR), enclosed by the magnetic field gradient of a mirror magnetic field, a sputtering is carried out by utilizing the resultant high density plasma, and the drawing-out of low energy ions and the production of a highly active plasma at a high electron temperature are made compatible. Moreover, a microwave leading window 6, by using a vacuum waveguide 10, can be set apart from a plasma generating chamber 11, and moreover, a magnetic field distribution in which the magnetic field intensity varies suddenly at the border of the plasma generating chamber 11 by a yoke 12 furnished around the vacuum waveguide 10 can be realized. Consequently, the attachment of a conductive material film to the microwave leading window 6 is prevented, and the reflection of microwaves is also eliminated. In such a composition, even the metallic ions can be drawn out continuously and stably for a long time.
