A self-propelled cleaning device having a cylindrical side cover has a suction body capable of moving transversely to the forward direction. The side cover is held by a base via a suspension. When cleaning corners of a room, the suction body moves by a wall and as the suction body moves to a corner, the movement amount of the suction body is changed. When an obstacle touches the cleaning device, the side cover moves, and the article touches a side cover switch, and the direction of the article is detected.

A control device includes a shot-pulse control unit that provides, at a time of starting a synchronous motor, a predetermined current to each phase of a stator of the motor for a short time; a detecting unit that detects a current flowing through each phase when the predetermined current is provided; an estimating unit that estimates a position of the rotor by comparing detected values; a voltage control unit that controls application of a voltage to the synchronous motor based on a high-pressure side pressure of the compressor when the compressor is failed to be started due to any cause; and a magnetism-resistant section having a conductive layer sandwiched by insulating layers. The magnetism-resistant section covers a portion of a substrate of the control device, and a portion at which the conductive layer is exposed is in contact with the housing or a part conducting heat to the housing.

A compressor having an internally mounted inverter and having improved safety at low cost is provided. The compressor has a motor; a compressor mechanism driven by the motor; a first housing section having an opening and within which the motor is housed; a second housing section which is mounted on the first housing section and which closes the opening; a fixing member which fixes the second housing section to the first housing section; a controller which is provided on the first housing section and which controls the operation of the motor; a power supply section which supplies power to the controller; a protective cover which covers the controller; and a power source control apparatus which stops the supply of power to the controller by the power supply section or carries out a prescribed safety measure operation when the protective cover is removed from the controller. The protective cover has a shape which restricts manipulation of the fixing member by covering a manipulation section of the fixing member when the controller is covered.

A shifting mechanism shifts at least one of a sheet accommodating portion and feeding portion, thereby changing a position of the feeding portion relative to sheets. A pressure changing mechanism changes pressure between first and second separating portions. A contact force controlling portion controls the shifting mechanism to provide a first contact force when the feeding portion starts a feeding operation, and controls the shifting mechanism, at a first timing, to reduce the contact force from the first contact force to a second contact force. A pressure controlling portion controls the pressure changing mechanism to provide a first pressure between the first and second separating portions when the feeding portion starts the feeding operation, and controls the pressure changing mechanism, at a second timing, to reduce the pressure from the first pressure to a second pressure while nipping the separated sheet between the first and second separating portions.

An image forming device includes an image forming section, a plurality of recording-medium supply units, a transportation guide forming a plurality of transportation paths, a full-width cleaning member, a plurality of recording-medium separating members, and at least one partial cleaning member provided for each recording-medium separating member. The plurality of transportation paths joins together to provide a single main transportation path reaching the image forming section. The full-width cleaning member is disposed in the single main transportation path. The full-width cleaning member has a full-width cleaning portion wider than a recording medium. Each partial cleaning member has a partial cleaning portion wider than is the corresponding recording-medium separating member.

An image forming device capable of sufficiently removing paper dusts on a sheet thereby providing high quality image. A sheet transport path 38 is defined between a sheet supply section 7 provided with a separation pad 13 and a sheet supply roller 12 and an image forming section 5. Along the sheet supply section 7, at least a first paper dust removing roller 9b having a width slightly greater than the width of the separation pad 13 and a second paper dust removing roller 10b having a width slightly greater than the sheet width are disposed. Paper dusts generated upon friction against the separation pad 13 are removed by the first paper dust removing roller 9b, and paper dusts spreading over entire surface of the sheet are removed by the second paper dust removing roller 10b.

A novel process for producing clay derivatives having porous structure comprises hydrolyzing a metal alkoxide such as Al(OR).sub.3, Ti(OR).sub.4 and Si(OR).sub.4 in which each R represents a linear or branched hydrocarbon group having from 1 to 6 carbon atoms, deflocculating the resulting hydrolyzate with an acid to obtain a hydrous metal oxide sol, and reacting the sol with smectite.The thus obtained porous clay derivatives have larger interlaminar interstices and a larger surface area than conventional ones. The interstices can be arbitrarily controlled by the acid amount. In addition, the derivatives are thermally stable so that they can be widely utilized in various fields as pigments, encapsulating agents, adsorbents, catalysts, carriers for catalysts and the like.

Provided is an electric motor in which magnets are reduced in size, thus achieving a reduction in cost, and in which a magnetic torque and a reluctance torque are effectively used by adjusting the magnetic flux density to improve the efficiency, thus achieving a reduction in size and cost. The electric motor is equipped with a rotor that includes a cylindrical rotor iron core in which main magnetic poles and auxiliary magnetic poles are alternately disposed in the circumferential direction, a substantially V-shaped magnet insertion hole that is provided for each of the main magnetic poles and whose convex portion faces a rotor center and is centered on a d-axis passing through the rotor center and the circumference-wise center of the main magnetic pole, and two magnets per pole that are embedded in the magnet insertion hole in a substantially V-shaped manner.
