Title: Thin-film transistor
Inventor: JINNO MASASHI
IPC: G02F1/1368
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To increase a voltage holding rate and to improve a contrast ratio by constituting a thin-film transistor(TFT) in such a manner that the current directions of two channels are different from each other. SOLUTION: The current directions of the respective channel regions 11Na, 11Nb are reversed from each other in the warped shape of polcrystalline silicon(p-Si) 11 in the constitution obtd. by intervening LD regions 11Lc to 11Lf of, for example, about 1 to 2μm length on both sides of gate electrodes 13Ga, 13Gb. Such LD regions 11Lc to 11Lf usually is required to be >=0.5μm in order to relieve strong electric fields, but if the LD regions are shrunk by the misalignment of masks, the strong electric fields are not relieved and lead currents are no longer suppressed. In such a case, the constitution to direct the directions of the currents in the channels reverse from each other, by which the leak currents are suppressed by another channel having a series relation with the one channel even if the leak currents are generated in the one channel.

Title: Flow measuring method for tank and device for the method
Inventor: ABE KOJI
IPC: G01F23/18
Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To measure a liquid level and a flow rate from a signal by a level gauge alone so as to save costs by introducing a level signal detected by the level gauge to a flow computing unit for converting the level signal into an outflow flow rate. SOLUTION: A sampling unit 11 samples a level signal of a tank 1 detected by a level gauge 2 at a fixed time interval. The sampling signal is introduced into a flow computing unit 13 with a previous sampling signal stored in a memory 12, and an outflow flow rate is found. That is, in the flow computing unit 13, an outflow flow rate is found by computing according to the following expression; outflow flow rate = (previous sampling value - this-time sampling value) × tank internal area/sampling time. A tank internal area is varied by the size of the tank 1, so that it is rewritable. As computing for finding a flow rate cannot be carried out in supply of liquid into the tank 1, a switch 14 serving as a command unit for stopping flow computing is arranged for stopping computing for a flow rate.

Title: Overflow avoiding system for data drive type processor
Inventor: NAITOU HIROMIKI
IPC: G06F15/82
Filed: 1988-12-26
Abstract: PURPOSE:To avoid overflow without needing a program change, for which labor and time are needed, and a separate processor by suitably inputting an execution delay instruction to a surrounding pipe line and suitably delaying arithmetic processing. CONSTITUTION:Based on a flow graph and the number of tokens which can be simultaneously transmitted to a surrounding pipe line 17, an execution delay time corresponding to the number of overflow tokens is calculated and inputted automatically or based on the node designation of a manual to the surrounding pipe line 17 in a period just before the overflow is generated in the flow graph. With receiving the execution delay instruction token, an execution delay instruction processing part 5 delays the arithmetic processing of an arithmetic processing part 13 by the execution delay time and avoids the overflow of the surrounding pipe line 17. Thus, without needing the program change, which needs the time and labor according to the manual for avoiding the overflow, or the separate processor, the overflow can be effectively avoided.

Title: Method of producing reduction gas and burner
Inventor: YOSHIGAE TAKEO
IPC: F23C99/00
Filed: 1989-12-19
Abstract: PURPOSE:To prevent soot from being generated by a method wherein butane is used as fuel, a specified amount water vapor is added to the fuel and then main fuel charged with the water vapour is burned while oxygen and air ratio being specified. CONSTITUTION:Butane of 7.7Nm<3>/hr is fed to a fuel feeding pipe 1 while cooling water is being flowed in cooling water feeding pipes 4 and 11. Water vapor of 3.5mol is supplied from a water vapor feeding pipe 2 to it and the mixed fuel is injected from injection holes 3 for the main fuel at a flow speed of 200m/sec and in turn oxygen is injected from oxygen injection holes 9 at a flow speed of 50m/sec and then burned under an air ratio of 0.43. Reduction gas got through this combustion has as its major constituent H2 and CO and further has a relation of H2/CO>=1. In the burner, when the mixed fuel and oxygen are injected at a high speed, a combustion occurs from a slight front side of a nozzle surface having injection holes 3 and 9 therein and further along with the cooling operation there is no damage at the nozzle surface. In addition, the fuel and oxygen to be mixed have a relative speed difference of 150m/sec, so that a dispersing and mixing of these two substances is sufficiently promoted, non- ignited substance such as soot or the like can be restricted and thus there is no presence of soot in the reduction gas.
