Title: Gas recirculation device
Inventor: FUNAKURA MASANORI
IPC: F23C9/08
Filed: 1986-12-09
Abstract: PURPOSE:To prevent unstable combustion caused by an eccentric flow of combustion gas in an aft-and-fro direction of a boiler by a method wherein a recirculation gas feeding system for each of a front side of the boiler and a rear side of the boiler is provided with a device capable of adjusting an amount of recirculation gas to be fed into a furnace. CONSTITUTION:In case that burners 2 at a front side and a rear side of a boiler at the lower most stage of a furnace 1 are ignited, a degree of opening of a damper for an adjuster 10 for adjusting an amount of recirculation gas at the front side of the boiler is made slightly large and a degree of opening of the damper for a device 12 for adjusting an amount of recirculation gas at the rear side of the boiler is made slightly small. This is branched into a recirculation gas line 9 at the front side of the boiler at the downstream side of the recirculation gas amount adjusting device 8 and a recirculation gas line 11 at the rear side of the boiler. If burner 2 at the front side (or rear side) is diminished and burner 2 at the rear side (or front side of the boiler) is ignited, a degree of opening of the damper of the adjusting device 10 (or 12) is fully closed and a degree of opening of the damper for the adjuster device 12 (or 10) is made large. With this arrangement, a strength of gas flow at the bottom part of the furnace 1 is substantially equal at the front side of the boiler and the rear side of the boiler and it is possible to prevent a circulation flow of the combustion gas from being occurred.

Title: Engine controller
Inventor: OKUDA EIICHIRO
IPC: F02P5/153
Filed: 1986-12-08
Abstract: PURPOSE:To improve the responsiveness by detecting the output shown in the figure of an engine by an in-cylinder pressure sensor buried into a cylinder and controlling ignition timing so that the difference from a set aimed engine output becomes zero. CONSTITUTION:The output shown in the figure of an engine is detected by the output value of an in-cylinder pressure sensor 6 for detecting the pressure in the combustion chamber of an engine 5. Further, an engine controller 9 calculates the ignition advance value corresponding to the ignition timing on the basis of the information supplied from the sensors such as throttle position sensor 3 and intake air quantity sensor 4 and the in-cylinder pressure sensor 6, and controls an ignitor 12. Therefore, even in the case when a load is applied sharply onto the engine in idling, the stable operation state can be maintained.

IPC: G07F9/10
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To improve the room temperature cooling transient characteristic of a cooling storage room at the time of starting operation based upon a 1st operation system and to shorten the operation time of a refrigerating cycle. SOLUTION: After the stop of operation based upon a 2nd operation system, an electromagnetic valve 61 is opened, an indoor heat exchange 11 in a heating storage room 1 is connected in series to the discharge side of a compressor 3 and the heat exchange 1 is filled with a high pressure regrigerant (a thick solid line). As a matter of course, a low pressure refrigerant displayed by a normal solid line exists in an indoor heat exchange 12 in a cooling storage room 2 and a high pressure refrigerant displayed by a thick solid line exists in an outdoor heat exchange 4.  Since the heat exchange 11 in the room 1 has been filled with the refrigerant at the time of starting the compressor 3 based upon the 1st operation system, the temporary shortage of a heating medium is not generated in the heat exchange 12 differently from a conventional case and the room temperature cooling transient characteristic of the room 2 can be quickly reduced as compared with the conventional case.

Title: Yarn strip cutter of winder
Inventor: SHINDO NAOHIKO
IPC: D01D7/00
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To reduce a switcing error at yarn switching time by keeping transitional yarn in a noncontact condition from a cutter at yarn switching time, and adding a tensile force member to contact the transitional yarn and the cutter with each other when tensile force of the transitional yarn increases and reaches a preset value to cut the transitional yarn in the next place. SOLUTION: A traveling yarn strip Y is completely capatured by a catch ring of an empty bobbin and a slit arranged in an end part of the empty bobbin, and transitional yarn is wound in a barrel shape round the outermost peripheral surface of a fully winding bobbin, and when tensile force of the transitional yarn increases, a tensile force member 7c is pushed downward. When it reaches preset tensile force, a cutter 7c and the transitional yarn contact with each other for the first time, and therefore, the transitional yarn is cut by the cutter 7c. Therefore, the traveling yarn strip Y is reliably captured by the empty bobbin side, and since the traveling yarn strip Y is cut for the first time when tensile force increases to a prescribed value, winding fastening by high tensile force is caused in a yarn strip package, quality of the yarn strip package is not impaired.
