  • Exercise measuring instrument
    Patent number: 4962469
    Abstract: An exercise measuring instrument according to the present invention employs an acceleration sensor which comprises a piezoelectric piece having a pair of piezoelectric elements stuck to each other. An output waveform of the acceleration sensor is supplied to an amplifier, gain of which is changed in accordance with an exercise mode selected out of a walking mode, an exercise-walking mode and a jogging mode, and thereby an output level of the amplifier is kept at somewhat an equal voltage level, although the voltage level of the output waveform of the acceleration sensor is different between the exercise modes. This improvement allows an accurate measurement of exercise.

  • Musical tone generating apparatus for synthesizing musical tone signal by combining component wave signals
    Patent number: 4961364
    Abstract: A global envelope is input by a user and stored in a global envelope memory. At the respective envelope-controlled sine wave generators are generated envelope functions of the respective orders by modifying the input global envelope. The envelopes of component wave signals of a plurality of orders are independently controlled by the envelope functions having the respective orders in the generators, and a musical tone signal is synthesized by combining the envelope-controlled component wave signals.

  • Apparatus for extracting envelope data from an input waveform signal and for approximating the extracted envelope data
    Patent number: 4958552
    Abstract: An envelope extracting circuit extracts an envelope from the waveform sampled by a musical tone sampling circuit, and stores the envelope data into a memory. An envelope approximating circuit approximates the envelope data as stored in the memory by the function data such as linear or exponential function data. The original envelope is approximated by a limited number of function waveforms whose characteristics change at switching points.

  • Electronic drum
    Patent number: 4947725
    Abstract: A vibration plate and cushioning plate are arranged, as a layered structure, within a drum shell in that order as viewed from the inner bottom of the drum shell toward a batter head with a vibration sensing/electric signal producing sensor attached to the vibration plate. A cushioning member is located within the drum shell to elastically support the cushioning plate between the inner bottom surface of the drum shell and the vibration plate. The cushioning member includes an externally urging section for externally urging the vibration plate toward the drum shell and an elastic support section which, when receiving an external strike force exceeding a predetermined value, is elastically deformed toward the inner bottom surface of the drum shell.

  • Manually sweepable printing apparatus
    Patent number: 4949283
    Abstract: A manually sweepable printer stores data transferred from a data forming apparatus such as a wordprocessor in a memory. The printer is placed on printing paper and manually swept to sequentially print the data stored in the memory. The manually sweepable printer separately receives printing data and print control data from the data forming apparatus and separately stores the received data. In the printing operation, the printing data is printed on the basis of the print control data.

  • Dual-frequency, dielectric anisotropy liquid crystal optical device
    Patent number: 4946260
    Abstract: An ON electric field for turning on (allowing light transmission) a liquid crystal optical device and an OFF electric field for turning off (shielding light) the liquid crystal optical device are selectively applied to a liquid crystal material of the liquid crystal optical device. The ON electric field is applied so as to obliquely align liquid crystal molecules with respect to substrates constituting the liquid crystal optical device, thereby obtaining an ON state. The ON electric field has an electric field for driving the liquid crystal molecules and a non-electric field for generating a state wherein no electric field is applied to the liquid crystal molecules. The OFF electric field has an electric field for homeotropically aligning the liquid crystal molecules with respect to the substrates.

  • Hand-held manually sweeping printing apparatus
    Patent number: 4947262
    Abstract: A hand-held manually sweeping printing apparatus includes a manually manipulatable housing. A data input section, a memory, a printer head, a roll of ink ribbon, and an encoder are mounted within the housing. When a user holds the microcopier and sweeps it across a piece of paper, the printer head can print image data on the paper. Since the printer head is movable in response to various conditions caused by the pressure applied to the piece of paper, or surface conditions of the paper, a high-quality printing is realized. The data input section may be replaced by an image sensor, in which case the information on an original can be read and reproduced on the piece of paper.
