Title: Front-wheel driving force control device in four-wheel traveling device of large dump truck
Inventor: KATO MASAYA
IPC: B60K17/356
Filed: 1992-11-24
Abstract: PURPOSE:To enhance control responsiveness by equalizing actual inflow pressure of a variable displacement hydraulic motor with a set inflow pressure by controlling displacement of the variable displacement hydraulic motor, so as to optionally set front wheel driving force. CONSTITUTION:At the time of four-wheel drive traveling, pressure oil is fed by a main controller 23 to a pressure receiving chamber 14a of a clutch 14 to bring the clutch 14 into a contact state. Simultaneously, an electric current is fed to a solenoid of an electromagnetic proportional valve to set displacement at a predetermined value, and displacement of a variable displacement hydraulic motor 13 is set at a fixed value to hydraulically drive front wheels 2. In the main controller 23, inflow pressure of the variable displacement hydraulic motor 13 is set and this inflow pressure is set within a pressure range having an upper limit and a lower limit. When actual inflow pressure of a first or a second main circuit 16, 17, detected by a first or a second pressure sensor 21, 22, deviates from the range of set inflow pressure, the main controller 23 controls displacement of a variable displacement hydraulic pump 15 to bring differential pressure to zero. Consequently, a displacement control range is reduced and the control responsiveness is enhanced.

Title: Electric iron
Inventor: UENO SEIICHI
IPC: D06F75/26
Filed: 1989-12-04
Abstract: PURPOSE:To display the temperature of an iron base after an electric iron is used and to prevent an accident of a burn and the like by providing a display means to display the temperature of the iron base; a detecting means to detect the power source feeding time and the no feeding time, and to deliver a signal to a control means; and a power source means to charge when the power source is being fed, and to be a backup power source when the power source is not being fed. CONSTITUTION:Since an electric charge is given to a power source means 4 when a power source is being fed, the power source means 4 begins to feed the power source under the condition the power source is not fed. However, since a detecting means 5 detects that the power source is not fed, and outputs to a control means 3, the control means 3 does not feed the current to a heating means 7, but inputs only the output signal from a temperature detecting means 1, and displays it on a display means 2. And when the power source in not being fed, the temperature of an iron base 8 is lowered gradually. The control means 3 inputs constantly the signal of the temperature detecting means 1 which is contacted to the iron base 8, and outputs it to the display means 2. The display means 2 which received the signal from the control means 3 displays the input value. And when the temperature of the iron base becomes to the value not dangerous to the human body, all the display is put out, informing that it is not dangerous by touching.

Title: Traveling wave type ultrasonic motor
Inventor: ICHIKAWA SATOSHI
IPC: H02N2/00
Filed: 1989-12-04
Abstract: PURPOSE:To enhance heat dissipation of a stator by filling a high heat conductive heat sinker in an air gap between a cover and a thin disclike part of the stator. CONSTITUTION:If heat is generated from a piezoelectric element 4 of a stator 5 by driving a motor 30, partial heat is transferred and dissipated from the thin disclike part of the stator 5 to a cover 2 and a case 1 through the stationary part of the cover 2. In this case, since high heat conductive silicone grease 20 is filled in the thin disclike part between the part of the stator 5 to the cover 2 and a rotor 8 under pressure contact of the air gap between the stator 5 and the cover 2, most of the heat is transferred directly to the cover 2 through the grease 20. Thus, dissipating effect of the heat generated at the element 4 is improved to suppress temperature rise of an adhesive layer inserted between the element 4 and an elastic member 3, thereby enhancing the temperature limit of an ultrasonic motor.

Title: Engine speed controlling method
Inventor: OMORI NORIO
IPC: F02D41/16
Filed: 1988-12-14
Abstract: PURPOSE:To stabilize idling engine speed right after an engine starts by driving a control valve in the direction in which the amount of inlet air is increased than usual for a preset period after the engine is ready to start. CONSTITUTION:In case that a throttle valve 16 is closed and an engine 10 is in idling, engine speed is determined by an air control unit 60. When it is lower than a desired value, the rate of time for electrifying an electromagnet coil 51 in an electromagnet mechanism 50 is increased and the opening of the air control valve 30 is enlarged to increase the amount of auxiliary air by-passing a throttle valve 16 and to raise idling engine speed. When the idling engine speed is a desired value or more, the opening of the air control valve 30 is diminished to decrease the idling engine speed. For a few second to a few min. after the engine starts, a comparison level indicating a desired value is lifted up by a timer circuit and displaced in the direction of increased amount of auxiliary air to enhance and stabilize the idling engine speed.
