Title: Device for impressing biased magnetic field
Inventor: MIYAJIMA HIROSHI
IPC: G11B5/02
Filed: 1991-10-09
Abstract: PURPOSE:To provide a small size and a thin device with simple constitution by providing a shape memory element in a supporting/driving means. CONSTITUTION:When the switch 9 of a leaf spring 3 side is turned on, the leaf spring 3 is heated by joule heat and the shape of the leaf spring is restored to return to a plane shape. On the other hand, since the switch 13 of the leaf spring 5 side is turned off, the leaf spring 5 is deformed with a twist elastically. Normally, since the shape restoring force of an SMA is considerably stronger than the force by elastic deformation, a permanent magnet 1 is rotated in accordance with the twist of the leaf spring 3, thus, the direction of the biased magnetic field is inverted. Similarly, when the switch 9 is turned off and the switch 13 is turned on in this state, the leaf spring 5 is heated by the joule heat, the shape of the leaf spring 5 is restored to return to a plane shape. Then, the permanent magnet 1 is returned to a state shown in a figure.

Abstract: PURPOSE:To quantize the spectrum parameter of a voice signal with a smaller number of bits than before. CONSTITUTION:A division part 100 divides the voice signal, frame by frame, and divides the spectrum parameter, which is found by a predetermined degree, by dimensions which are less than said degree. A vector quantization part 110 searches code books 150-1-150-N by the number of the dimensions as to the divided spectrum parameters and outputs code vectors of plural candidates in distortion increasing order. A cumulative distortion calculation part 160 finds cumulative distortion from all degrees for the combination of code vectors. A minimum decision part 170 selects and outputs the combination of code vectors which minimize the cumulative distortion to quantize the spectrum parameter.

CONSTITUTION:The first and second measuring devices 50, 60 are used in an abutted state so as to interpose spacers 11, 12 made of rubber therebetween. Each of the measuring devices 50, 60 is constituted so that the central part and peripheral parts 2 of a plate shaped structure are connected at four places by means 3 and the central part is used as a load plate 1 receiving load. Each load plate 1 is held in the air by four beams 3 projecting from the peripheral parts 2. When load is applied to the load plate 1 from above, shearing strain is generated at the places of the beams 3. By utilizing the shearing stress generated in the beams, the strain quantities of strain gauges 4 are electrically amplified and detected to measure a wt. The strain gauges 4 are adhered to both side surfaces of the beams 3 at four places so as to form four pairs respectively equipped with four resistors R1-R4. Then, in order to add up the strain quantities of said strain gauges 4, both measuring devices 50, 60 are connected in a freely detachable manner by a cable and the total wt. is displayed on a display device.
