Abstract: An electromotive scooter comprises an electric drive motor and a power source indicator that provides a visual indication when the electric drive motor is in the on condition. An electric circuit supplies electric current to an acoustic device, causing it to emit an acoustical warning, when the electric drive motor is in the on condition and a seat load sensor does not sense a load on the rider's seat.

Abstract: For an electromotive scooter which gets its driving force from an electric motor driven by batteries mounted thereon, and which has a power source unit for an electromotive scooter which supplies power of nominal value of 48V to the electric motor that requires high voltage to exert high driving performance and also supplies power of nominal value of 12V via an auxiliary power source to the other electric devices in such a manner that even in a case of large fluctuation of voltage in the main power source, a stable power is assured for the electric devices, a control unit, for example, making it possible to employ as these devices those products for common use on the market.

Abstract: Disclosed herein are methods and means of producing novel growth hormone-like proteins derived from the pituitary gland of fishes belonging to the order Pleuronectina, the family Paralichthydae, which are useful in the growth promotion for fishes, by genetic engineering using cloned genes.

Abstract: An electromotive scooter body is a hollow construction made of fiber reinforced plastics, so that the body is strong and light to reduce load on a traveling motive power source. The body can be separated into upper and bottom parts and the hollow of the bottom part accepts many batteries, so that a center of gravity of the scooter can be low.

Abstract: An electric vehicle which has motor wheels of the direct-drive outer-rotor type which permit simplification and compaction of the motor wheels. Current regulating covers introduce ambient air for cooling the motors and reduce air resistance, and batteries and control devices are disposed symmetrically relative to the axial line of the vehicle body and to axial lines of the axles so as to reduce and uniformly distribute the weight of the vehicle. All these devices contribute jointly to increasing the range of the electric vehicle.

Abstract: A dual drive system for an automatic record player of a type in which programmed music selection can be carried out. The drive system includes a mechanical first drive system for mechanically driving the pickup arm and an electromagnetic second drive system for driving the pickup arm using an electromagnetic force. Circuitry is provided for selecting between the two drive systems in accordance with the selected operational mode of the player or the position of the pickup arm.

Abstract: A disc player apparatus which features, inter alia, a disc and drive support structure including a turntable having a lower face adapted to receive thereon the disc to be played back and a lower disc support unit which is movable into and out of a position below the turn table for holding the disc between the turn table and the disc support unit.
