Title: Electronic musical instrument
Inventor: KOSEKI SHINYA
IPC: G10H7/02
Filed: 1994-03-25
Abstract: PURPOSE:To reproduce reverberations of a keyboard musical instrument such as an acoustic piano with a high fidelity. CONSTITUTION:A struck string sound when a pedal is not stepped on and a plucking tone when the pedal is stepped on is absorbed, and stored as waveform data (a) and (b) in a waveform memory 11. When a musical tone signal is generated, waveform data (a) in a scale distinctive waveform memory 11-i corresponding to the key code KC of a pressed key are selected and when the loudness pedal is stepped on, waveform data (b) are selected. A musical tone signal generation part 10 generates a musical tone signal with the selected waveform data. Consequently, a musical tone (sound to which a resonance sound is added when the loudness pedal is stepped on) corresponding to the operation of the loudness pedal is generated.

Title: Steering device for automobile
Inventor: NAKAJIMA HITOSHI
IPC: B62D1/16
Filed: 1986-04-07
Abstract: PURPOSE:To improve travelling safety by providing means for discriminating whether the vehicle speed is below a set value or not and being actuated to perform a switching operation of the transmission ratio characteristic only when it is below the set value. CONSTITUTION:Control means F controls the operation of transmission ratio changing means D, when selecting means E selects a transmission ratio characteristic. In the concrete, only when a signal from vehicle speed discriminating means G indicates that the vehicle speed is below a set value, it is actuated to switch the transmission ratio characteristic. This prevents deviation of the amount of wheel steering change from an expected value which would be cause by switching of the transmission ratio characteristic during high speed travelling. Additionally, it is avoided that the characteristic is switched during steering, causing change in the amount of wheel steering change, while the handle steering angle is kept constant.
