摘要:
The present invention is transportable economically in a flat state, and easy to attach and detach, and can provide a curved surface simply while maintaining decoration and strength without craftsmanship and absorb sound. Slits are provided on a rectangular board panel comprising two or more layers of a hard material and a soft material. Two or more layers comprising a hard material and a soft material are laminated on a rectangular board panel, and slits having a length of ½ to ¾ of the vertical side are provided thereto. The use of slits makes formation of curved surfaces easy. Since there is no need to reinforce the outside to maintain the strength thereof, the board panel can be removed easily. Even if an external pressure is applied to the board panel, the flexibility of the hard material divided by the slits and the elastic characteristic of the soft material cause the pressure to be dispersed and absorbed, and sound to be absorbed.

The present invention is a toner for developing electrostatic charge image containing a wax derived from a plant cholesterol, an electric charge-controlling agent, a coloring agent and a binding resin. The toner is suited for use in the electromagnetic induction-heated fixing system which is capable of heating the heating member up to a predetermined fixing temperature in a short period of time, makes it possible to maintain images free of irregular luster or fouling for extended periods of time and is, further, suited for being fixed at a low temperature.

It is an object of the present invention to provide a valve seat product in which the amount of hard particles added to improve the wear resistance of a valve seat of an internal combustion engine is increased, and is excellent in the mechanical strength and machinability. In order to achieve the object, an iron-based sintered alloy material for a valve seat is employed which is made to contain a first hard particle having an average primary particle diameter of 5 to 20 μm and a second hard particle having an average primary particle diameter of 20 to 150 μm in a texture, wherein a particle size distribution curve measured by laser diffraction scattering analysis has N peaks (N is an integer equal to or larger than 2) and when particle diameters corresponding to the peak top positions are denoted as DT1 to DTN, a peak top particle diameter difference between neighboring DTn-1 and DTn(|DTn-1−DTn|: n is an integer equal to or larger than 2 and equal to or smaller than N) is in the range of 15 to 100 μm in at least one neighboring DTn-1 and DTn; and the total area ratio occupied by both of the first hard particle and the second hard particle constituting the mixed hard particle in the texture of the iron-based sintered alloy is 10 to 60% by area.

A composite sheet comprising an upper layer 2 and a lower layer 3 both made of a substantially inextensible sheet which are partially bonded to each other at a large number of joints 4. The upper layer 2 forms a large number of outward hollow projections 5 in the area other than the joints 4. The projections 5 and the joints 4 are arranged such that the projections and the joints alternate in one direction to make lines and that the projections in each of the lines are out of alignment with the projections in the adjacent lines.

There is provided an oscillator using a high-frequency crystal resonator which can satisfy the drive level needed for the crystal resonator and expand a variable frequency range. An oscillator having an oscillation circuit CC for oscillating the resonator SS is provided with a limiter circuit LM1 as a load of the resonator SS which is inductive and is a load circuit for limiting an oscillation amplitude. According to this configuration, the action of the limiter circuit LM1 allows satisfaction of the drive level needed for the crystal resonator and expansion of the variable frequency range.
