摘要:
An electronic sewing machine includes a sewing machine motor that vertically drives a sewing needle via a rotation of a main shaft; a stitch-pitch setting unit that sets a stitch-pitch in sewing manually fed workpiece cloth; a consumed thread amount detection unit that detects consumed thread amount of at least either of a needle thread or a bobbin thread consumed in each ongoing sewing cycle; a consumed thread amount calculation unit that calculates consumed thread amount based on an output from the consumed thread amount detection unit; and a speed control unit that controls rotational speed of the sewing machine motor based on calculated result of the consumed thread amount calculation unit so that an amount of manual cloth feed equals the stitch-pitch set by the stitch-pitch setting unit.

A lighting device 12 of the present invention includes a plurality of linear light sources 17 arranged parallel to one another, and a light reflecting member 40 arranged on the side of the linear light sources that corresponds to the opposite side of the light emitting side. The linear light sources are arranged so that a narrow-interval area 17A where the arrangement interval thereof is relatively narrow and a wide-interval area 17B where the arrangement interval is relatively wide are provided. An opening section 50 is formed in the light reflecting member. The opening section 50 is provided so that the opening ratio as a ratio of the area of the opening section 50 in the entire light reflecting member 40 is higher at an area corresponding to the narrow-interval area 17A, than at an area corresponding to the wide-interval area 17B.

A frame is narrowed by a technically reasonable design, without technical limitation for frame narrowing which tends to be considered troublesome when bent-tube type fluorescent tubes having U-shaped bent portions are to be alternately arranged to face each other nor without the trouble of storing the bent-type fluorescent tubes in a chassis while being manufactured. A backlight device (2) is provided with a backlight chassis (23) wherein a plurality of fluorescent tubes (21) having electrodes are arranged and stored, and an inverter circuit board is arranged on the rear surface of the backlight chassis (23). Furthermore, the backlight device (2) is provided with a storing section (30), which is attached to the backlight chassis (23) by storing a conductive holding section for holding the electrodes. With the storing section (30) attached to the backlight chassis (23), the electrodes of the fluorescent tubes (21) are electrically connected to a light source lighting circuit board arranged on the rear surface of the backlight chassis (23).

The object is to provide a light-emitting transistor material which is high in both luminescent property and mobility when used as a light-emitting transistor device.A light-emitting transistor device is provided in which light emission of a specific pyrene-based organic compound is used for a light-emitting layer of a transistor device.
摘要:
The fluorescent lamp retaining member retains two lamp units each including two fluorescent lamps that have electrodes at both ends thereof, a bundling member that bundles a wire from each of electrodes at one end of the two fluorescent lamps, and a conductive member that connects electrodes at the other end of the two fluorescent lamps through a conductive path. The fluorescent lamp retaining member holds the vicinity of the central of each of the fluorescent lamps so arranged in parallel as to set the bundling members in the same direction. The fluorescent lamp retaining member allows one retained lamp unit to rotate relative to the other retained lamp unit adjacent thereto, and so retains the lamp units adjacent to each other that the bundling members and conductive members are arranged alternately after one lamp unit has been rotated.

A sewing machine includes a sewing machine motor that vertically drives a sewing needle via a main shaft; a sewing speed commander that produces a command sewing speed determined by rotational speed of the sewing machine motor; a stitch-pitch specifier that specifies a stitch pitch to be applied to manually fed sewing operation; a consumed thread amount detector that detects a consumed needle-thread amount in each ongoing sewing cycle; a sewing speed controller that controls sewing speed at the command sewing speed when the command sewing speed is equal to or less than a predetermined reference sewing speed, and that controls sewing speed at a target sewing speed calculated based on the consumed needle-thread amount and the stitch pitch when the command sewing speed is greater than the reference sewing speed.
