Title: Change-over method for cycle of variable-speed motor by inverter
Inventor: FUNAKI MASAO
IPC: H02P5/74
Filed: 1980-06-06
Abstract: PURPOSE:To prevent temporary drops in motor speeds, by a method wherein when a plurality of motors are to be changed over from a high-speed running state on a commercial power source to a low-speed running state on an inverter power source, said change-over is effected with time intervals. CONSTITUTION:A dust-collecting equipment comprises a plurality of motors 1a and 1b, blowers 2a and 2b, for example, driven by the respective motors, dust collectors 3a and 3b, for example, and dust-collecting dampers 4a, 4b.... When the motors 1a and 1b are to be changed over from the high-speed running state on a commercial power source to the low-speed running state on an inverter power source through a free running state according to the dust-rising characteristics, said change-over is effected with time intervals as shown in the figures A and B. Thereby, it is made possible to prevent temporary drops in the motor speeds due to the lag of the control system and a large drop in the dust-collecting capacity resulting therefrom.

Title: Heat treatment apparatus for cast iron pipe
Inventor: TANAKA AKIO
IPC: C21D9/08
Filed: 1979-06-14
Abstract: PURPOSE: To perform a ferrite-conversion annealing economically by a procedure in which a ductile cast iron pipe made by a centrifugal casting method is taken out of a casting machine in a red-hot state and soon put into a heat treatment furnace where it is passed though plural chambers to gradually cool it.  
     CONSTITUTION: The ductile cast iron pipe 8 made by the centrifugal casting machine 1 is taken out in a red-hot state of 800W850°C and then put into the heat treatment furnace 12 provided near the machine 1. In the heat treatment furnace 12, the pipe 8 is passed through the first furnace chamber 14 of 750°C, the second furnace chamber 15 of 700°C, and the third furnace chamber 16 of 650°C, each having a humidity regulated by the burner 19 while being turned in order to prevent becoming an oval form, to gradually cool the pipe 8, whereby cementite is almost decomposed into ferrite and graphite due the gradual cooling at near the transformation point A(750°C) and the texture is sufficiently converted into ferrite having a high toughness. Since the cast iron pipe is heat-treated in a red-hot state without being cooling once, the amount of heat energy used in annealing can be greatly saved.

Abstract: PROBLEM TO BE SOLVED: To provide a method for polishing a cylindrical body by a grinding wheel capable of obtaining a surface roughness equivalent to a surface roughness obtained when the cylindrical body, particularly, manufactured roll is polished by a polishing grinding wheel of a bigger size in spite of polishing it by a polishing grinding wheel having a predetermined size. SOLUTION: A crossing angle when both of a rotary axial line of a grinding wheel 3 and a rotary axial line of a cylindrical body W are viewed from plane direction is a non-right angle. The cylindrical body W and the grinding wheel 3 are rotated. The grinding wheel 3 is moved from one end to the other end of the cylindrical body W while keeping a polishing pressure constant for uniform polishing of a cylinder. A contact line at the time of polishing an end face of the grinding wheel 3 is within a scope of a radius line 4 passing through the center of a central hole on the end face of the grinding wheel 3 or a line 4 parallel with a radius line to such extent that it is not deviated from the central hole for polishing.  On the proper halfway of the polishing contact line 4 on a side where rotation direction of the grinding wheel 3 agrees with rotation direction of the cylindrical body W, rotation speed of the grinding wheel 4 agrees with rotation speed of the cylindrical body W for minute and multi-directional polishing.

Title: Combustion controller for vaporization burner
Inventor: HASHIMOTO ATSUSHI
IPC: F23N1/02
Filed: 1985-04-12
Abstract: PURPOSE:To improve stability in combustion state with a proper air-fuel ratio by providing a control section which corrects by increase and decrease for a specified time the quantity of primary air supply corresponding to the change in the flow rate characteristics of an electro-magnetic pump when the combustion amount of a vaporization burner is increased or decreased. CONSTITUTION:In the judgement of whether the hot air temperature should be lowered, if NO is indicated, the controller is returned to the starting of hot air temperature control, and for YES the control to lower the hot air temperature is executed. Namely, when the hot air temperature is lowered, the pulse width for an electro-magnetic pump is decreased to a smaller width, and next the rotational speed N of ACF is lowered to Nn-1, and at the same time the rotational speed Nn-1 is further lowered by DELTANn-1. Then after a specified time DELTAt has elapsed, the rotational speed of ACF is controlled to return to Nn-1. In other words, when the combustion amount is changed by controlling the air supply amount to increase or decrease corresponding to the increase and decrease of flow rate according to the pump characteristics, it is made possible to match the change in the fuel supply amount according to the electro-magnetic pump to the air supply amount and improve the stability in the state of combustion.

Title: Game machine
Inventor: IOKI SADAO
IPC: A63F7/02
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To improve the operation of a game machine by determining whether entering a probability variable state or not by a drawing, and displaying the result by mode information, and also, generating a deflection in a manifestation frequency for specified combinations from among combinations which do not generate a special game state. SOLUTION: A game control device 100 determines whether entering a probability variable state or not by a drawing by a probability variation acquisition determining random number. This is not displayed to the outside, and a player cannot see it. Whether the probability variable state is generated or not by the drawing result, is set as mode information. Then, by the state under the probability variable mode and the state under normal mode, a manifestation rate for specified losing patterns from among the combinations of special patterns is made different for the processing. That is, in the case of the probability variable mode, a big winning probability is increased, and a big winning is made easier to occur in the next time. The higher probability is kept for a specified period of time. Thus, an intention to search for entering the probability variable mode is induced, and the game continuation property can be improved.
