Abstract: An electric motor is equipped with a rotor having multiple rows of slits arranged along a radial direction. A permanent magnet is buried only in some of the slits, namely the ones closest to the center of the rotor or the innermost slits, to drive the motor using both magnet torque and reluctance torque. This improves the torque output.

Abstract: A submicron CMOS transistor is mounted on the same substrate together with an analog CMOS transistor, a high voltage-resistance MOS transistor, a bipolar transistor, a diode, or a diffusion resistor, without degrading the characteristics of these components. When a punch-through stopper area is formed on a main surface side of a semiconductor substrate, an area in which an analog CMOS transistor, a high voltage-resistance MOS transistor, a bipolar transistor, a diode, or a diffusion resistor is formed is masked, and for example, an ion injection is then carried out. Thus, a punch-through stopper area is formed in the area in which a submicron CMOS transistor is formed, while preventing the formation of a punch-through stopper area in the area in which an analog CMOS transistor, a high voltage-resistance MOS transistor, a bipolar transistor, a diode, or a diffusion resistor is formed.

Abstract: In a screen-printing apparatus for printing creamy solder paste on a substrate by attaching a screen mask to the substrate, a predetermined measuring position of the mechanisms in the screen-printing apparatus is measured three-dimensionally by a three-dimensional measuring device. Based on the measured result, a predetermined measuring point on an object to be measured is determined on a position relative to the origin of the mechanical coordinate system in the screen-printing apparatus, and the origin position on a control program can be set. As a result, machine adjusting operation and teaching operation in the screen-printing apparatus can be simplified with high accuracy.

Abstract: A musical instrument has play pistons incorporated in a trumpet-shaped housing at the upper central part in the front-and-back direction. An air vibration sensor for inputting voices is provided at the end surface on the front side of housing. When a player inputs voices into air vibration sensor simultaneously with the player's operation of play pistons, a musical tone is generated having a tone pitch that is determined by a combination of the operation of play pistons and the frequency of the voice sound signal. Rings formed of transparent or translucent resin and emitting light by energization of light-emitting elements are incorporated at the foot of play pistons. Through energization of light-emitting elements in accordance with performance data, light emission of rings guides playing. Thus, the player can easily play and practice the musical instrument, such as a trumpet, that determines the tone pitch of a musical tone in accordance with a combination of operation of a plurality of play operators.

Abstract: Elements in a triple-well MOS transistor are prevented from being destroyed due to an increase in current consumption or a thermal runaway of a parasitic bipolar transistor. A triple-well NMOS transistor comprising a P well area formed within an N well area and a MOSFET formed in the P well area, an impurity-diffused area having a lower impurity concentration than an N+ drain area is formed close to the N+ drain area, thereby restraining substrate current. The impurity concentration of the P well area is increased to reduce the current gain of a parasitic bipolar transistor. To further reduce the current gain, a punch-through stopper area may be formed. The impurity concentration of the impurity-diffused area is set to equal that of an N− LDD area 31 of a fine CMOS device integrated on the same substrate 1. These areas are formed during a single ion injection step.

Abstract: A CPU 31 reads out musical tone control information such as tone color data and effect data from an external storage device 35 or retrieves it via an interface circuit 51. The CPU 31 supplies the musical tone control information to a tone generator 41 and an effect circuit 42 in order to control the tone color of a musical tone signal and the effect added to the signal, using the musical tone control information. When the musical tone control information is not applicable to the tone generator 41 and the effect circuit 42, the information is substituted by musical tone control information applicable to the tone generator 41 and effect circuit 42 and stored in a ROM 33 for the use later on. On a display unit 13 there is displayed the name of substituted tone color data or effect data with information that a substitution has been made.

Abstract: There is provided an image forming apparatus that is capable of securing required printing quality by properly correcting a main scanning scale. In a pixel division modulating process, for each of one or more correction points (at l-th, m-th, and n-th pixels) on each of lines along which scanning is carried out on a photosensitive drum 11 by laser light, the final bit data of pixel-division-modulated pixel data of a pixel immediately preceding each correction point is added to the pixel data of a pixel located at the correction point as the leading bit data of the pixel-division-modulated pixel data of this pixel. The same processing as above is sequentially performed on pixel data of pixels located subsequently to the correction point to sequentially shift predetermined bit data of pixel data of pixels to pixel data of the respective following pixels, to thereby generate pixel data of a new pixel. The generated pixel data of the new pixel is outputted in synchronism with an image clock of a fixed frequency.
