IPC: C21C7/00
Filed: 1982-03-09
Abstract: PURPOSE:To refine steel to decrease the phosphorus concentration and sulfur concentration in an obtained product steel as low as possible, by combining the dephosphorization and desulfurization in hot metal with the reduction refining in a reduction refining  furnace. CONSTITUTION:For molten metal tapped from a blast furnace, the treatment of desiliconization by a desiliconization agent (for example: manganese ore) and the treatment of dephosphorization and desulfurization by adding a dephosphorization and desulfurization agent (for example: soda ash) are carried out. Then, this pretreated molten metal is flushed. At the same time, after charging it into a converter, O2 refining is carried out by injecting O2 gas onto hot metal M3 from a lance 8 inserted from the upper opening part of converter 7. Then, after finishing refining, the molten steel M4 finished with blowing is poured by dropping into a ladle 9 from a taphole 7b of the inclined converter 7. Then, the lower nozzle 10d of sliding nozzle 10 of the ladle 9 is inserted into the opening part 12a of the suitably inclined reduction refining furnace 12 from the ladle 9, and the molten steel M4 is tapped into the furnace 12 during controlling the poured amount by using the nozzle 10. Thereafter, O2 gas and Ar gas are injected from the tuyere 12b of this furnace 12, and the reaction of reduction is caused to proceed, the molten steel being refined so that the low phosphorus concentration and the low sulfur concentration are obtained.

Abstract: PURPOSE:To improve the graininess of a photosensitive material by incorporating a color non-developing coupler in a silver halide emulsion layer, incorporating also a compd. having a specified thiazole ring, etc., and an N-contg. heterocyclic compd. in a hydrophilic colloid layer. CONSTITUTION:A compd. (color non-developing coupler) which reacts with an oxidized body of a color developing agent but does not contribute to the formation of a picture image is incorporated into a silver halide emulsion layer. Further, a thiazole or benzothiazole compd. expressed by the formula I, or an N-contg. heterocyclic compd. expressed by the formula II is incorporated into a hydrophilic colloid layer. In the formula, Q is a nonmetallic atom group forming a thiazole or benzothiazole ring together with S and N atoms; X is an electron attractive group; Y is H, aliphatic or aromatic group, etc.; Z<1> and Z<2> are nonmetallic atom group forming 5- or 6-membered heterocyclic ring; Y<1> and Y<2> are H or substituent. Since a color non-developing coupler, and a heterocyclic compd. expressed by the formula I and II are contained in the photosensitive material, the graininess of the photosensitive material is improved without reducing the sensitivity nor without increasing fog.

Title: Feeder for image forming machine
Inventor: YASHIRO MASAHIKO
IPC: B65H1/02
Filed: 1988-02-20
Abstract: PURPOSE:To improve workability and to reduce defective feeding by providing a guide member projectable/sinkable with respect to a rotary feeding body thereby simplifying the mountability of a sheet member. CONSTITUTION:The side face Sb of many sheet members is arranged manually, then the sheet members S are pushed in along the surface 25a and a guide plate 29 until the sheet member S contact with a guide board 26b. Since the end section 29e is pressed by the weight of a press member 28 and the sheet member S, an elastic body 31 contracts to push down the projecting end section 29e to a height same as that of a sheet feed roller 27 projecting slightly from the surface 25a so as to contact the lowermost section Sa of the sheet member directly with the sheet feed roller 27 thus bringing out waiting state. The sheet feed roller 27 rotates upon turning ON of a switch to lead the sheet member S, sheet by sheet, from the lowermost section Sa through a sheet feed section between feed rollers 14, 14. Since the sheet feed roller 27 is made of such mate rial as having high friction against the sheet member S, the sheet member S can be fed reliably sheet by sheet.

Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To enable a trainman to quickly report proper information to a train, upon his/her detection of an obstruction on a railroad crossing, and automatically stop the train in the condition where there is no time to lose. SOLUTION: An alarm signal transmission part 4 sends a railroad crossing position information in such a state as contained in an alarm signal. Also, a train speed measurement part 12 outputs the travel speed of a train, and a train position measurement part 13 outputs the position of the train on the basis of data received from a GPS satellite. Map and travel distance database 14 stores the data of a travel distance between the position of the railroad crossing and another point on train travel rails. Furthermore, an alarm signal receiving part 9 computes a braking distance from the travel speed data and reads out a travel distance from a current train position to the railroad crossing, from the map and travel distance database on the basis of the railroad crossing position information and the train position information.  Then, the alarm signal receiving part 9 judges when to brake for stopping the train, based on the braking distance and the travel distance, and reports to a trainman accordingly. It the train approaches the railroad crossing and there is no time to be lost, the signal receiving part 9 outputs a train stop control signal.

Title: Resetting circuit for microcomputer
Inventor: FUKAI TOSHIHIKO
IPC: H03K17/22
Filed: 1982-03-11
Abstract: PURPOSE:To prevent a malfunction of a microcomputer, by applying a reset signal to the microcomputer, in case when supply voltage is varied. CONSTITUTION:In case when the voltage of an electric power source line 7 rises suddenly, the voltage of an integrating circuit consisting of a capacitor C1 and a resistance R2 rises slowly, and when it exceeds the reference voltage of a Zener diode ZD1, a Zener current is generated. By the Zener current, reset voltage is generated in the collector of a transistor Q1. When the electric power source line 7 is cut off, the charge of the capacitor C1 is discharged through the transistor Q1, therefore, in this case, reset voltage is generated. When a voltage change of the electric power source line 7 drops slowly and the Zener current becomes zero, the output voltage of the transistor Q1 becomes equal to supply voltage from the electric power source line 7. This voltage is shaped as to its waveform by a hysteresis buffer, and becomes a reset signal.
