A high-pressure fuel pump control device capable of reducing current consumption, increasing pump durability, and promoting a rise of fuel pressure from startup. The high-pressure fuel pump control device comprises a fuel injector valve for directly injecting fuel in a common rail into a combustion chamber and a high-pressure fuel pump for feeding the fuel under pressure to the common rail. The high-pressure fuel pump comprises a pressurization chamber, a plunger for pressurizing the fuel in the pressurization chamber, a fuel passage valve disposed in the pressurization chamber, and an actuator for actuating the fuel passage valve. The control device includes a control unit for executing output control of a drive signal for the actuator to vary a discharge rate of the high-pressure fuel pump. The control unit starts outputting of the actuator drive signal during a period from operation start to a point in time at which the actuator drive signal becomes able to issue in a predetermined crank angle phase, and sets timing of stopping the outputting of the actuator drive signal to a point in time at which the fuel pressure in the common rail has boosted over a predetermined value per unit time.

A solid oxide electrolyte material comprising an electrolyte material 50 using oxygen ions as carriers as a base material and a lithium-containing compound 60 added to the base material as a sintering additive is sintered at a sintering temperature of 1300° C. or lower to produce a solid oxide electrolyte 100. This solid oxide electrolyte material can reduce the sintering temperature to extend the range of choices of components of a solid oxide fuel cell and suppress reactions between other components to reduce the manufacturing cost. This solid oxide electrolyte material further can produce a solid oxide electrolyte with sufficient denseness and high gas tightness capable of suppressing fuel leak to improve the electromotive force and output.

A delivery warmer comprises a catalytic combustion heat generating device, a container accommodating cooked food, and a container casing accommodating the container. In the catalytic combustion heat generating device, a fuel tank stores liquefied fuel gas. A nozzle section gasifies and injects the liquefied fuel gas. A combustion section introduces gas mixture of the gasified fuel gas and air, and causes a catalytic reaction for burning the gas mixture. An igniter ignites the gas mixture and commences the catalytic reaction. Thus, heat generated from the catalytic combustion heat device is used to warm the container accommodated in the container casing. The cooked food is kept warm and tasty for a long time.

A rotor (10) includes a plurality of permanent magnets (14) disposed around a shaft (12) at generally equal intervals, and a plurality of laminated core members (16) disposed between the permanent magnets (14) so as to form magnetic poles. The laminated core members (16) are formed by stacking a plurality of core-laminations (26) made of magnetic materials and an integral core-lamination, and joining them to each other. The integral core-lamination includes a plurality of core-lamination sections each having a shape the same as that of the core-lamination (26), and connecting portions (46) for connecting adjacent core-lamination sections with each other. When the large number of core-laminations (26) and the integral core-lamination are integrally joined by a press-fitting process, the laminated core members (16) are connected with each other in such a relative arrangement of a finished assembly that a space for locating the permanent magnet (14) is defined between the adjacent laminated core members (16), and thus an integral laminated rotor core (48) is formed.

To reduce torque ripples appearing in an output torque of an electric synchronous motor, the rotor (10) is divided into 2.sup.n rotor elements (101, 102, 103, and 104) the rotor elements of each of 2.sup.n-1 pairs of rotor elements (101, 102; 103, 104) being circumferentially shifted from one another around an axis of the rotor by an angle corresponding to a half of the wavelength (.lambda.) of a first (A) of "n" kinds of cyclic torque ripples (A and B) to cancel the first kind of torque ripple, and the 2.sup.n-1 pairs of rotor elements (101, 102; 103, 104) being arranged to be grouped in 2.sup.n.sup.-2 sections of rotor elements, each section including two pairs of rotor elements, and the 2.sup.n-2 sections of rotor elements being circumferentially shifted from one another around the axis of the rotor by an angle corresponding to a half of a wavelength (.lambda.) to cancel a second of the "n" kinds of torque ripple, and eventually, the rotor structure being structured so that the rotor elements are further circumferentially shifted from one another to cancel the "n"th torque ripple component.

An anti-rolling structure for a double headed piston of a disc cam type reciprocative compressor, comprising a cylinder block (1) through which a plurality of pairs of front and rear cylinder bores (4) are provided in parallel to a drive shaft (3) rotatably secured in the center of the cylinder block (1), and a double headed piston (8) slidably inserted in the respective pair of cylinder bores (4) for reciprocation in the longitudinal direction. A disc cam (13) having opposite sinuous surfaces (13') and rotatably accommodated within a cam chamber (5) is fixedly secured to the drive shaft (3), and a pair of front and rear cam rollers (14F, 14R) are arranged between the disc cam (13) and the piston (8) in a slidable and rotatable manner so as to nip the disc cam (13) between both cam rollers (14F, 14R) to transmit the rotation of the disc cam (13) to the piston (8) as a reciprocation in the longitudinal direction thereof. The front and rear cam rollers (14F, 14R) are positioned so that the axes of rotation thereof are not included in the center plane defined by longitudinal axes of the piston (8) and the disc cam (13) but disposed, respectively, in the opposite areas sectioned by the center plane with a substantially equal deviation from each other from the center plane. According to the above structure, the rolling motion of the piston (8) can be effectively restricted throughout the operation of the compressor.
