Title: Oil feeder
Inventor: MATSUMURA HIROSHI
IPC: B67D7/32
Filed: 1991-07-25
Abstract: PURPOSE:To judge the kind of oil accurately, effect a full tank oil feed automatically and prevent the operator from neglecting to put an oil feed nozzle back in place after completion of oil feed by a method wherein the kind of the oil to be fed is automatically judged, the oil is automatically fed only in the case of a correct result of the judgement and, after the tank is judged to be full, the completion of oil fed is informed. CONSTITUTION:An oil kind judging means 70 judges whether to feed gasoline or light oil based on the detection signal from a gas sensor GS. If the judged oil kind does not agree with the registered oil kind, a wrong oil kind informing means 71 actuates an informing device to give a warning. In the case of an automatic full tank oil feed, a full tank judging means 72 judges the tank to be full based on the detection signal from a flow amount pulse generator 4 when the number of times that oil feed has been interrupted reaches a predetermined value. On the other hand, if the judged oil kind is judged to agree with the registered oil kind, an oil feed means 73 starts oil feed. When the tank is judged to be full, an oil feed completion informing means 74 gives a warning to that effect. The above-mentioned features permit an accurate judgement of oil kind and an automatic full tank oil feed and prevent the operator from neglecting to put an oil feed nozzle back in place after completion of oil feed.

Title: Switching hub
Inventor: YAMASHITA KAZUHIRO
IPC: H04L12/46
Filed: 1997-08-04
Abstract: PROBLEM TO BE SOLVED: To prevent the overflow for the receiving buffer of a port having a high transmitting speed by setting the transfer length of frame data which are transferred in a single time at different value according to the difference of port transmitting speeds. SOLUTION: The input rate of frame data 43 set to a receiving buffer 13n of a 100M Etherport is larger than the input rate of frame data 44 set to a receiving buffer 14m of a 10M Etherport. Meanwhile, the transfer length of the frame data 41 sent from a communication control LSI 11n of the 100M Etherport to an internal bus is set larger than the transfer length of the frame data 42 sent from a communication control LSI 12m of the 10M Etherport. As a result, the rate at which the frame data are outputted from the buffer 13n is larger than the rate at which the frame data are outputted from the buffer 14m. Therefore, the increase of the frame data stored in the buffer 13n can be suppressed and accordingly the overflow of the buffer 13n can be prevented.
