Title: Telephone conference system by packet communication
Inventor: MURANO KAZUO
IPC: H04M3/56
Filed: 1980-11-12
Abstract: PURPOSE:To prevent an switchboard side from being loaded even if conferees increase in number, by performing processing for telephone conference at every terminal. CONSTITUTION:A voice signal is converted by a decoder into a digital signal, which is packeted by a packeting circuit and, after time data is inserted by a time inserting circuit, sent to a packet switching network, thereby performing simultaneous multiple-address transmission to other conferees. At the reception part of each terminal, packets from another conferee are received by a packet buffer 6 and arranged by a time-order arranging circuit 7 according to transmission time; and they are added by an adder 8 to generate a synthesized sound, which is reconverted by a decoder 9 into an analog signal to be supplied to a handset. Consequently, processing for conference is performed only in each terminal, so that even if conferees increase in number, that never increases a load on a switchboard.

Title: Method and machine for testing roll abrasion
Inventor: KIHARA JIYUNJI
IPC: G01N3/56
Filed: 1980-11-12
Abstract: PURPOSE: To obtain the same effect with the surface state of a roll after a test by an actual machine, by equalizing a frequency of contact between the roll and a material to be rolled for rolling distance to that of the actual machine, by reducing the roll diameter and a roll peripheral speed to about one-tenth those of the actual machine.  
     CONSTITUTION: A testing device consists of an unwinding device 9, a rolled- material supply device equipped with a guide roll 10 for the unwinding device, a rolling device which has a roll diameter and a roll peripheral speed about one- tenth those of an actual machine while having a heating furnace exit and a rolling device entrance at a distance short enough for temperature control, a winding machine 7, and a tensile-force measuring device 4 for controlling winding- machine torque. The said roll is attachable and detachable and uses, for example, a grain roll material, but other materials are usable. Consequently, a ≤1mm thickness, maximum ≤30mm width material to be made into a plate is worked by about 500m hot rolling to check the abrasion state of the roll.

Abstract: PURPOSE:To provide a CT secondary circuit opening safety device which shortcircuits the secondary circuit in a short time when an abnormal voltage is generated, by installing two electrodes made of a low melting point metal opposingly with a fine gap reserved in-between so that discharge takes place with a specified voltage. CONSTITUTION:With a fine gap 4 in-between, two electrodes 3, 3 are installed opposingly in a cylindrical vessel 2 made of an electrically insulative material, and leads are connected with them so that a CT secondary circuit opening safety device 1 is formed. The dimensions of the micro-gap 4 should be such that discharge takes place with a specified voltage. At least one of the electrodes 3, 3 is made of a metal or alloy having a low melting point, for example, solder. The safety device is connected with the secondary circuitry of a current transformer in such a way as parallel with the load. When the secondary circuit is opened and a failed voltage is generated, discharge is generated in the micro-gap 4 with the specified operating voltage, and the electrodes 3, 3 are melted and shortcircuited. Thereby the secondary circuitry can be maintained in the shortcircuited condition certainly and in a short time using a safety device of simple structure.
