A mixing and blending method for powdered or granular material includes supplying pulsating vibration air into an airtight tank from a bottom thereof. An airtight tank having a porous bottom plate on which the material is stored is provided for the mixing and blending method. In the system pulsating vibration air is generated by periodically increasing and decreasing the amount of blowing air at a low frequency. Pulsating vibration air is introduced into the airtight tank from the bottom of the airtight tank so as to generate air flow going upward through the porous bottom of the airtight tank. As a result, powdered or granular material stored on the porous bottom plate in the airtight tank is uniformly mixed and blended in the airtight tank while continuously moving up and down as in a convectional manner.

In an orthodontic device, a main body (1) has an opening (1a) formed to permit detachable passage of a principal wire and a flange (2) formed in a mesiodistal direction so that the device is fixed via said extension flange (2) to an band to be fitted over the crown of molar. The width (W) of the extension flange (2) in an occluso-gingival direction is made greater than the width (B) of said main body (1) in the same direction.

A lobed rotor-type pump has a drive shaft, a pump housing, an eccentric rotor journal, a rotor, three working-fluid chambers, intake and discharge ports, and a communication passage. The pump housing has a circumferentially-extending peri-trochoidal curved surface in its inner periphery. The eccentric rotor journal is fixedly connected to the drive shaft. The rotor is slideably fitted to the eccentric rotor journal. The rotor has three lobes equi-distantly spaced circumferentially around its outer periphery so that the rotor rotates eccentrically while keeping the lobes in sliding contact with the peri-trochoidal curved surface. The three working-fluid chambers, which are defined between respective three lobes and the peri-trochoidal curved surface, rotate in synchronism with the rotor. The intake and discharge ports are provided in the housing to input low-pressure incompressible fluid and to output high-pressure fluid. The communication passage is formed in the housing for communicating a first working-fluid chamber, decreasing in volume during the compression stage, and a second working-fluid chamber, increasing in volume during the expansion stage, to permit flow of incompressible fluid from the first chamber to the second chamber.

A movable member slides on a fixed member. The movable member is made of aluminum alloy. An inner layer coats the movable member. The inner layer is made of a material capable of adhering to the aluminum alloy. An outer layer coats the inner layer and contacts the fixed member. The outer layer has greater hardness than the hardness of the inner coating layer.

A safety operation system for a manipulator is provided with a first operation section. The first operation section has a first movable section, and outputs a first operation signal representing the position and angle of the first movable section. A failure detecting section detects failure of the first operation section on the basis of the first operation signal, and outputs a detection signal. When failure of the first operation section is not detected, a conversion section converts the first operation signal into a control signal. A second operation section has a second movable section which moves in accordance with movement of the first movable section, and outputs a second operation signal generated in accordance with movement of the second movable section. A comparison section compares the control signal with the second operation signal, and outputs a deviation signal used for opening the second movable section. A management section receives the detection signal, and supplies the comparison section with a signal for making deviation signal zero, thereby prohibiting the second movable section from being driven. A display section displays data on the failure of the first operation section and/or data on the current position of the first movable section, on the basis of a signal output from the management section.

The present invention is intended to operate a semiconductor device at high speed with low voltage. A circuit configuration is used in which the transfer impedance between a common I/O line and a data line is changed depending on whether information is to be read or written. A current/voltage converter is provided which includes a MISFET different in conduction type to a select MISFET. Thus, the speed of reading information is increased. An intermediate voltage generator having high driving capability is provided. Thus, the circuit has sufficient driving capability for an LSI having large load capacitance. A voltage converter is provided which converts a data line supply voltage or word line supply voltage to a higher voltage. Therefore, stabilized signal transmission is ensured.

A conductive composition comprising conductive particles made of a mechanical composite powder of copper or nickel covered with silver and a binder mainly containing bis-phenol A type epoxy resin (diglycidyl ether of bisphenol A) having 1600 to 5500 of molecular weight method for manufacturing a printed circuit substrate comprising the steps of printing the conductive composition on an insulating substrate and partially curing it in a range of 20 to 70% of completion as determined from DTA reactivity data. Thus, the conductive composition can manufacture an inexpensive circuit in simple steps as a whole with good solderability using low melting point solder and having high bonding strength. The method can manufacture the circuit by using the same conductive composition.

A variable displacement vane compressor for an air conditioning system used in an automobile has a cylinder assembly having a bore which receives a rotor to form at least one crescent or compressing chamber between the rotor and the bore. The crescent chamber receives a refrigerant which is returned from the air conditioning system. The rotor has vanes which are extendably fitted therein so that the free end of the vanes are in contact with the circumferential inner surface of the bore during the rotation of the rotor, whereby when the vane passes through the crescent chamber, the refrigerant received therein can be compressed. The amount of the refrigerant introduced into the crescent chamber is adjustable in response to a change of a cooling load at the air conditioning system.

This electromagnetic coupling structure includes a laminated body that is laminated with an inner dielectric layer interposed between inner conductive layers, one pair of outer dielectric layers facing each other with the laminated body interposed therebetween, and one pair of outer conductive layers facing each other with the one pair of outer dielectric layers interposed therebetween. The one pair of outer conductive layers include wiring portions and conductive patch portions disposed at front ends of the wiring portions, and the conductive patch portions have portions longer than the wiring portions in a direction perpendicular to an extending direction of the wiring portions. In the laminated body, a hole passing through the inner dielectric layer and the inner conductive layers is arranged, and the one pair of outer conductive layers are electromagnetically coupled through a metal film formed inside the hole.
