Title: Heating method of ladle
Inventor: HARA KAZUAKI
IPC: B22D11/10
Filed: 1999-08-27
Abstract: PROBLEM TO BE SOLVED: To greatly cut the volume of a carbon material by setting a steel discharging temperature of a converter, improve unit requirements of a ladle refractory by loosening thermal attack, and also save energy by cutting the using volume of a fuel gas when the ladle is heated with a burner. SOLUTION: After continuous casting and sludge exhausting are completed, a ladle 1 is put on a steel receiving carriage 5 and transferred to a steel receiving area D2 of a converter 3 by the steel receiving carriage 5. Then, the ladle 1 is kept in the steel receiving area D2 on the steel receiving carriage 5 under a stand-by condition for a given time. After the stand-by time, the ladle 1 for receiving the molten steel from the converter 3 is immediately heated before receiving the molten steel. In this method, the ladle 1 is rapidly heated in a given time when the ladle is kept in the stand-by condition in the steel receiving area D2 of the converter 3, by means of a regenerative burner 10 attached to a ladle cover 12 covering an upper opening of the ladle 1.

Title: Low nox burner
Inventor: UEDA JUNICHI
IPC: F23D14/70
Filed: 1990-09-11
Abstract: PURPOSE:To reduce the generation of NOx in exhaust gas and to prevent the occurrence of flashback of flame to a fuel-air mixture passage outlet by a method wherein a flashback preventing plate is located in a combustion air passage and on the upper stream side of the fuel-air mixture passage, and a rim part is located between a burner port and the combustion air passage. CONSTITUTION:A rim part 9 having a flame stabilizing distance of 2-7mm is located between the slit of a burner port 1 and a combustion air passage outlet 8, and a flashback preventing plate 11 inclined from the central part of a combustion air passage 10 toward a fuel-air mixture passage 6 is mounted facing both sides of a burner body 2. This constitution induces a part of air in the combustion air passage 10 to the outlet of the passage 6 by means of the flashback preventing plate 11 and vertically crosses fuel-air mixture injected through the passage 6, whereby flame is blown off and prevented from flashback to the passage 6. Further, by locating the rim part 9, the burner port part 1 generates a recirculation region for fuel-air mixture injected through the passage outlet 8. Flame is stabilized and fuel-air mixture having low oxygen concentration is fed through the outlet 8 to flame formed at the burner port 1 to reduce the generation of thermal NCx.

Filed: 1985-10-28
Abstract: PURPOSE:To prevent the wrong use of a credit card by permitting the transaction only when the identification number of a responsible person is supplied in case an amount exceeding a set level is supplied. CONSTITUTION:A CPU 5 checks the coincidence between the identification number read out of a card reader 2 and that supplied from a pin pad and then compares the amount data supplied by the ten keys 12 with the amount set to a memory area 82 of a RAM 8 when it is decided that a confirmation key 112 is operated. Thus it is checked whether the transaction amount is larger than the set amount or not. when the transaction amount is smaller than the set amount, a confirming process is carried out. While a request for input of the identification number of a responsible person is displayed on a display device 3 if the transaction amount is larger than the set value. Then the responsible person is called by a clerk in charge and then supplies his/her own identification number by means of the keys 12. Thus the CPU 5 compares the input identification number with the number set at the memory area 81 of the RAM 8 and confirms the transaction if the coincidence is obtained between both identification numbers.

Title: Dressing method for grinding wheel
Inventor: ABE SEIICHI
IPC: B24B53/00
Filed: 1986-10-14
Abstract: PURPOSE:To permit dressing to be sufficiently performed preventing abrasive grains from falling off, by combining abrasive grains by a binding agent, equipped with elasticity, to form a dressing grinding wheel so that it large increases a cut while short reduces the dressing time. CONSTITUTION:If an abrasive grain 11a of a dressing grinding wheel 11 collides against an abrasive grain 10a of a grinding wheel 10, the protruded abrasive grain 11a sinks into a binding agent 11b because it provides elasticity. While if the abrasive grain 11a of said grinding wheel 11 passes through a part of the abrasive grain 10a of the grinding wheel 10, the abrasive grain 11a, sunk into the binding agent 11b, is returned to the former position by elastic force of the binding agent 11b protruding from its surface and cutting off a binding agent 10b. As a result, the dressing grinding wheel 11, which can mainly cut off the binding agent 10b of the grinding wheel 10 preventing the abrasive grain 10a from falling off, enables a dressing speed to be increased by large applying a cut, and dressing efficiency can be enhanced.

On the other hand, when the TR 16 is turned on, then the TR 14 is turned on at the same time and a circuit point 13 is discharged via the TR 14 and then the potential at the circuit point 13 is decreased rapidly up to Vss to turn off all TRs 15-16 turned on. Then the capacitor 12 is charged again via a resistor 11 and the potential of the circuit point 13 rises. Similar operation is repeated and an oscillation signal is obtained at the circuit point 13.

Filed: 1994-10-07
Abstract: PURPOSE: To solve various problems in wiring using a dual gate FET, by electrically connecting a second gate electrode to a source electrode when a first gate electrode is closer than the second gate electrode to a source region. CONSTITUTION: In a semiconductor device which has a dual gate field-effect transistor having first and second gate electrodes provided on an upper part of a channel region, a pattern is formed such that a second gate electrode 54 is electrically connected to a source electrode 51 in advance. A first gate electrode 53 of the first and second gate electrodes is closer to a source region, and the second gate electrode 54 is closer to a drain region. As the second gate electrode 54 and the source electrode 51 are thus connected with each other within the pattern, the transistor, viewed from outside of the pattern, can be used similarly to an ordinary single-gate FET. Therefore, when a circuit is to be constituted with this transistor, wiring for the second gate is not required.
