Inventor: YOSHIDA TOSHIYUKI
IPC: B02B3/08
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To prevent both a switch for rice polishing and a switch for cooking from being simultaneously on even when the switch for cooking is turned on by mistake during rice polishing and thus prevent the useless consumption of electric power due to counter electromotive force by supplying electric power to a motor through the switch for rice polishing only when the switch for cooking is off. SOLUTION: The motor 50 of a cooking apparatus is equipped with a rotor 51 having a rotor winding and with stator widings 52, 55 at both sides. The stator widing 52 has a plurality of windings 53, 54. Here, the on contact 56b of the switch for cooking connected to the connecting parts of both the windings 53, 54 and the off contact 56c to which both a contact 57a of the switch for rice polishing 57 and a contact 58a of a normally-open switch 58 are connected are selectively connected to a common contact 56a. Therefore, when the motor 50 is being driven by closing either the switch for rice polishing or the switch for cooking, all the switchs 56-58 and the winding 54 do not form a closed circuit even when the other switch is closed by mistake. Thus, wasting electric power can be prevented.

Title: Operation of blast furnace
Inventor: NAITO MASAAKI
IPC: C21B5/00
Filed: 1994-01-20
Abstract: PURPOSE:To raise the temp. in a furnace without increasing coke ratio and to stabilize the furnace condition by increasing the consumption of scrap in the case of lowering the temp. in the furnace in the blast furnace operation replacing a part of iron ore with the scrap. CONSTITUTION:In the case of replacing a part of the iron ore being the raw material with iron scrap in the blast furnace operation, the ratio of iron ore to coke becomes large at the circumferential part in the furnace due to the unevenness of the distribution of the iron ore and the coke in the furnace, and the temp. in the furnace is lowered over from a shaft lower part to a belly part in the blast furnace, and the stagnation of dropping of the charged raw material at this part and the increase of material stuck in the furnace are occurred to adversely effect the furnace condition of the blast furnace. This lowering of the temp. in the furnace is detected by observing cooling water temp. and the charging ratio of the scrap in the iron ore at the circumferential part in the furnace is made large to improve bad gas permeability, and gas reduction reaction of the iron ore is accelerated. The temp. in the furnace is raised without increasing the coke ratio and the furnace condition is stabilized to prevent the productivity of molten iron from being lowered.

Title: Overflow preventing valve
Inventor: MIZUGUCHI HARUOMI
IPC: F16K17/34
Filed: 1983-02-07
Abstract: PURPOSE:To allow a valve to be installed in a gas passage with a small diameter by forming a valve seat in a gas passage and providing a supporting portion of a ball valve directly below a valve port. CONSTITUTION:Under a normal gas usage condition, a ball valve 21 is stationarly supported on a valve receiving member 20; the gas flowing from a gas pipe connection port 11a passes through a gas passage 18a, a gas path 24, and a gas passage 17 in a shutter 12; then it flows into a gas passage 18b. On the other hand, when an abnormal condition occurs, the gas passage 18b is decompressed due to a decrease of resistance at the gas consumption side; a pressure difference is generated between upper and lower portions near the valve port 19a of a valve seat 19; and at the same time a pressure difference is also generated between it and the center portion directly below the valve port 19a by the gas stream quickly flowing into the valve port 19a through the annular gas path 24; the ball valve 21 is absorbed and guided to the decompressed side, i.e., upward, by these pressure differences; and it is coupled with the valve seat 19 in close contact by pressure to cut off the gas stream. Since the ball valve is supported by a supporting portion provided directly below the valve seat, the diameter of the supporting portion is not required to be made large with respect to that of the ball valve, and its height can be made low, thus the whole body can be easily made small- sized.

Title: Air conditioner of heat pump type
Inventor: KONDO SEIJIRO
IPC: F24F11/02
Filed: 1986-01-31
Abstract: PURPOSE:To converge a room temperature to a target room temperature in a short time, by decreasing an air cooling capacity when the room temperature approaches the neighborhood of a target room temperature, after the operation mode is changed from an air heating mode to an air cooling mode when the room temperature reaches the operation mode changing temperature, exceeding the air-conditioning operation stopping temperature. CONSTITUTION:When room temperature T1, T2 rises to reach air-heating operation stopping temperatures TS+DELTATP, TS-DELTATP, an operation stopping controller 25 controls an air-conditioning capacity changer 16 in order to stop an air heating operation (HS). If the room temperature continues to rise and approaches the neighborhood of operation mode changing temperatures TS+DELTATCH, TS-DELTATCH, the room temperature can be lowered down to the room temperature target value TS, because an operation mode changer 14 is driven to change the air heating operation into an air cooling operation (CO). The room temperature can be converged to the room temperature target values TS in a short time, not exceeding the target value TS, because the air cooling capacity is decreased (CD) by an air-conditioning capacity controller 27 when the room temperatures T1, T2 go down to the neighborhood of the room tempera ture target value TS.
