摘要： A DA converter circuit is provided for use in a ΔΣ AD modulator. The DA converter circuit includes a DA converter of segment switched capacitor type. The DA converter includes an operational amplifier, capacitors as connected in parallel to each other to supply electric charges to the operational amplifier, an electrically charging switch for switching of electrically charging electric charges onto the respective capacitors or not, and an electrically discharging switch for switching or not electrically discharging electric charges from the respective capacitors or not. A switch device performs either one of the electrically charging, the electrically discharging, grounding, and polarity inversion onto the respective capacitors. A controller controls the electrically charging switch, the electrically discharging switch and the switch device to execute a process of second-order DWA algorithm for performing a second-order noise shaping of a non-linearity of the DA converter circuit.

摘要： To correct the rotational balance of a spindle motor for rotating a disc on a base, a position and an amount of offset for correcting dynamic balance are determined from a position deviation signal, which is obtained from vibration transmitted to a rotary type position control unit located on the base similarly by lowering the servo gain thereof, and an index signal from the spindle motor. With this arrangement the dynamic balance of the spindle motor of an information recording/reproducing apparatus can be simply and accurately corrected without adding an accelerator sensor and the like.

摘要： A non-volatile semiconductor memory device is provided that includes a semiconductor substrate having a first conductivity type, and diffusion regions having a second conductivity type formed in the surface of the semiconductor substrate at predetermined locations. A gate insulation film is formed on the semiconductor substrate, and a conductive floating gate is formed over the gate insulation film. Additionally, an interpoly insulation film is formed on the upper surface of the floating gate, and a conductive control gate is formed over the interpoly insulation film. Further, the upper surface of the floating gate and/or the upper surface of the interpoly insulation film contain an oxidization suppressing substance. The oxidization suppressing substance suppresses the reaction with the oxidizer during post oxidization, and thus prevents the formation of bird's beaks in the upper and/or lower portions of the interpoly insulation film. Thus, the deteriration of the write/erase characteristics of the memory cells is reduced, and variations in the write/erase characteristics of the memory cells are lessened. The present invention also provides a method of manufacturing such a non-volatile semiconductor memory device.

摘要： An apparatus and method for casting metal in an evacuated mold cavity. The apparatus has a preferential suction zone through which a mold can be preferentially and effectively evacuated and a suction head sealingly fitting the upper surface of the mold. To the apparatus, is further provided a pressing means for pressing, in cooperation with the suction head, the mold against the inner bottom surface of a mold support chamber. By evacuating the mold through the preferential suction zone while pressing the mold to the bottom of the mold support chamber, a mold cavity is easily filled with a molten metal in such a manner to avoid casting defects such as insufficient filling, blow hole, surface fold, under fill, etc.

摘要： A lens actuator has a support shaft, a substantially cylindrical holder member slidably supported by the support shaft and an optical system. The holder member has at least four openings extending in the direction of the center axis of the support shaft. The optical system is held by the holder member so that the optical axis thereof is parallel with the center axis of the support shaft. A coil is mounted on the side of the holder member. An external yoke is provided around the holder member. An internal yoke is divided into the same number of portions to be inserted in the openings as the openings in the holder member. A magnetic field across the coil is generated by a magnet cooperating with the external yoke and the internal yoke. The rigidity of the holder member is enhanced so that the occurrence of resonance can be suppressed at the frequency used in the actuator.
