Title: Remote supervisory method in scpc communication system
Inventor: AKASAKI KOJI
IPC: H04B17/29
Filed: 1987-12-29
Abstract: PURPOSE:To collect the supervisory information of all the other stations by also slave stations in addition to a master station by switching the channel assignment of transmitting and receiving to the same assignment as that of master station by the slave station side when the station name designation of a polling signal is not a self station designation. CONSTITUTION:A master station 1 transmits the polling signal containing the station name designation, slave stations 2 and 3 receives this and the slave station 2 leaves the channel assignment as it is and starts to transmit the supervisory information of the self-station when the polling signal is the self-station designation. On the other hand, the slave station 3 switches the channel assignment of the transmitting and receiving to the same assignment as that or the master station 1, that is to say, it switches a transmitting channel frequency to f1 and a receiving channel frequency to f2 because the polling signal is not the self-station designation. As the result of this, the supervisory information transmitted by the slave station 2 is received by the master station 1 and the slave station 3. Thus, not only the master station but also the slave station 3 can collect the supervisory information of the other slave station 2.

Abstract: PURPOSE:To enable a light emitting diode of this design to emit light rays of short wavelength efficiently and stably by a method wherein a hetero-junction between a crystal selected from a specified group and a p-type silicon carbide(SiC) crystal is provided. CONSTITUTION:A light emitting diode is provided with a hetero-junction between a crystal selected from a group composed of an n-type gallium nitride(GaN) crystal, an n-type aluminum nitride(AlN) crystal, and an n-type gallium aluminum nitride (GaxAl1-xN:0<x<1) crystal and a p-type silicon carbide(SiC) crystal. Generally, distortion, stress, and various kinds of lattice defects occur to a hetero-junction between different substances, because the substances are different from each other in lattice constant, but in this case, as a hetero-junction is formed between SiC and GaN, AlN, or GaxAl1-xN whose lattice constant is very close to that of SiC, a light emitting diode of this design is able to emit light rays of short wavelength efficiently.

IPC: H05K5/06
Filed: 1989-12-22
Abstract: PURPOSE:To enhance a waterproof effect by providing an end face packing on the outer periphery of the hole for insertion of a display element. CONSTITUTION:The fin-like end face packing 14 is attached to the periphery of the hole for insertion 16 of the display element so as to seal a connection part between the electrode of the display element 10 and a plug 13.

By completely fitting the plug 11 in a socket 3, the plug 11 comes in contact with the end face packing 14. Pushing-back force from the end face packing 14 works to the plug 11 but the tight adhesion is maintained because a lock pin 12 is provided in the plug 11.
