Title: Method for protecting tuyere
Inventor: MATSUNAGA HISASHI
IPC: C21C5/34
Filed: 1988-01-27
Abstract: PURPOSE:To easily prevent erosion of a tuyere having a multipipe structure by specifying the line flow rates of the nonoxidizing gas for carrying the carbon material to be blown from the inside pipe of the tuyere and the oxidizing gas to be blown from the annular spacing between the inside pipe and the middle pipe. CONSTITUTION:The carbonaceous powder carried by the nonoxidizing gas is blown from the inside pipe of the tuyere having the triple pipe structure, the oxidizing gas from the annular spacing between the inside pipe and the middle pipe and a gas for cooling from the annular spacing between the middle pipe and the outside pipe into a molten iron from under the surface of the molten iron bath. The operation is made at the line flow rates (flow rate/ sectional area) of the above-mentioned nonoxidizing gas and oxidizing gas within the region shown by the hatched part of the figure 1 at this time. Further, the mixing ratio of the diluting gas is changed according to the line flow velocity of the above-mentioned oxidizing gas so that the operation is preferably made within the region shown by the hatched part of the figure 2. The erosion of the triple pipe tuyere for bottom blowing is thereby prevented and the stability and life of the tuyere are greatly enhanced at a low cost.

Title: Input protecting circuit device
Inventor: INOUE KAZUNARI
IPC: H01L27/02
Filed: 1986-01-24
Abstract: PURPOSE:To reduce the area of an input protecting circuit or the entire chip by utilizing a polysilicon under a bonding pad as a protecting resistor. CONSTITUTION:An input protecting circuit device has a pad 1, a polysilicon 2 disposed under the pad 1, a protecting transistor Q1 for connecting an extremely high voltage to a GND when the voltage due to a static electricity is applied, an N<+> type diffused layer 7, a polygate 9, a GND level 4 in the transistor Q1, and an input stage 3 to the interior of the device. Thus, since the polysilicon 2 under the pad 1 is used instead of the protecting resistor, a large area is not required at the periphery of the pad 1, and the area of occupying the input protecting circuit device in the chip can be reduced.

Title: Transmission start control system of local network
Inventor: OZAKI HIDEYUKI
IPC: H04L12/413
Filed: 1984-02-01
Abstract: PURPOSE:To decrease the probability causing an unnecessary collision for communication requiring the real time performance and the instantaneity by giving a transmission probability high in generation of an idle channel to a packet having a high priority. CONSTITUTION:When a transmission request from stations A and B is generated as shown in the thick arrows respectively during the transmission of the station A, the station B with low priority moves to a retest processing immediately after the channel is in use. On the other hand, even after the station C having a packet with high priority detects the busy state of the station A, the station C continues the supervision of the said channel. When the station A completes the transmission, the station C detects immediately that the channel is idle and starts the transmission. Moreover, the station B checks the idle channel at each retrial time and starts the transmission after the end of data transmission of the station C. Thus, the station C makes transmission with a minimum time delay without causing any collision.

Abstract: PURPOSE:To make a user feel as if the user sent and receives decisions of questioning and answering to and from television by reproducing a video tape and making a question with an image and a voice, extracting the encoded voice signal of a correct answer, and deciding and indicating whether or not an answer from an input part matches the correct answer. CONSTITUTION:When the video tape is reproduced and a PB signal is sent, its voice signal is inputted to a reception part 8. A demodulation part 9 detects only the encoded PB signal showing a correct answer which is not recognized by the user from various voices inputted from the reception part 8 and sends it as a binary signal to a total control circuit 10. When the signal sequence of the total control circuit 10 is 'A2#', number number input from an input switch 6 is expected. When a number is inputted within a specific time and it is a correct answer, an indication part 7 indicates that the number is correct, but when the number is a wrong number of when no number is inputted within the specific time, that is indicated and a voice signal is expected again. Conse quently, the user enjoys feeling as if the user sent and received signals to and from the television in two ways.
