Filed: 1983-03-31
Abstract: PURPOSE:To obtain a utilization factor of a transmission line which is equal to dynamic assignment without changing a transmission control procedure, etc., and to shorten remarkably an ineffective time by adding a simple constitution for providing a signal detecting means and a timer part on a master station. CONSTITUTION:A control part 70 sends out contents of an address counter 54 to a transmission line 40 from a driver 50 through a transmitting circuit 52 in order to send out a mark to each station. As a result, the mark to the slave station corresponding to the address counter 54 is sent out from the transmitting circuit 52. The corresponding slave station which has received the mark sends out a transmitting data in case when the transmitting data exists, and executes no response in case when said data does not exists. A timer 56 is started from when the mark is sent out. After the mark is sent out, a signal detecting part 62 monitors through a receiver 60 whether the data is sent out to the transmission line 40 from the slave station or not. When a signal detecting part 62 detects a fact that the data is sent out onto the transmission line, a detecting signal 72 is sent to a transmission discriminating part 64, and also the data on the transmission line is stored in a receiving buffer 68 through a receiving circuit 66.

IPC: H01L21/60
Filed: 1984-03-21
Abstract: PURPOSE:To block current to defects without giving adverse effects on other parts of a semiconductor substrate by a method wherein the surface of a zone having defect is coated with an insulation film, and next a zone uncovered with an insulation film is coated with an electrode film. CONSTITUTION:An nE layer 8 having a defect part 7 is coated with an insulation film 9, and a cathode electrode film 5 is not formed on the film 9. In the absence of the film 9, the gap between the surface of the nE layer and a contact electrode plate 6 is only 20-30mum; therefore, there is the possibility of contact of the electrode plate 6 with the nE layer 8 having the defect part 7 because of an unevenness which cannot be avoid existing on the surface of the plate 6. However, because of the film 9, main current never flows to the nE layer 8 having the defect part 7 even in the presence of an unevenness on the surface of the plate 6.
