A flame imitation manufacturing device of a fireplace relates to a flame imitation manufacturing device for simulating the burning state in a fireplace in the field of household appliances. Said device comprises a housing, a cross flow fan and a light source mounted on a base plate of the housing, a simulated fire chamber mounted on a back plate of the housing, ribbons mounted on the back plate of the housing by means of upper and lower strip bars and above the cross flow fan, and a light-transmitting glass plate mounted on the housing and in front of said ribbons. This invention, characterized in that said cross flow fan is a swinging one, is advantageous in that supplying wind non-directively by utilizing the swinging of said fan improves the flying state of ribbons so as to make the image state of burning flames more vivid, greatly enhances the authenticity of flames and lowers the cost thereof, and thus is adaptable to various flame imitation electrical-heated fireplaces and electrical appliances.

A damper device 100 is configured as a rotary damper, and a compensation device housing portion 110 is formed in a housing body 102 forming a housing 101. The compensation device housing portion 110 is formed in a bottomed cylindrical shape extending along the axial direction of a bottomed cylindrical hydraulic fluid housing portion 103 formed inside the housing body 102. The compensation device housing portion 110 has an external-air-side surface 112 projecting from the housing body 102 and exposed to the outside and a hydraulic-fluid-side surface 113 projecting into the hydraulic fluid housing portion 103. In this case, the compensation device housing portion 110 is formed, between a fixed vane 104 and a housing portion wall surface 103b, across a cell R1 and a cell R4 of four cells R1 to R4 into which the inside of the hydraulic fluid housing portion 103 is divided.

Proposed is a non-oriented electrical steel sheet as a steel material from which both a rotor core material having excellent fatigue properties and a stator core material having excellent magnetic properties after core annealing is performed can be obtained. The steel sheet is produced by hot-rolling a steel material including predetermined amounts of C, Si, Mn, and Al, followed by hot-band annealing, cold rolling, and cold-band annealing, wherein the steel sheet is cooled before the final cold rolling to a temperature of 90°C or below followed by aging conducted at a temperature of 100 to 300°, cold rolled in the first pass of the final cold rolling at a bite temperature of 70°C or below using a work roll with a surface roughness Ra of 0.05 to 3.0 µm, and subjected to the cold-band annealing at 700 to 950°C, so that D1 to D3 satisfy predetermined conditions, provided that the average crystal grain size of crystal grains with all orientations, the average crystal grain size of crystal grains with the orientation {411}<148>, and the average crystal grain size of crystal grains with the orientation {211}<011>, each measured by electron backscatter diffraction, are respectively represented by D1, D2, and D3.

The present invention relates to: a carbon composite material shaft in which a reinforcing bar made of a carbon composite material constitutes the inside of a space part of a shaft main body made of a metal material; and a carbon composite material motor spindle, in which a support pipe of a housing consists of an inner cylinder body made of a metal material and an outer cylinder body made of a carbon composite material, comprising a carbon composite material shaft. While the weight of the shaft and the housing can be reduced, the strength of the shaft and the housing can be increased, and the thermal variation characteristics of the shaft and the housing can be improved.
