Title: Pulse generating circuit
Inventor: KAMIOKA HIDEO
IPC: H02M3/28
Filed: 1990-08-22
Abstract: PURPOSE:To obtain a small capacity, high efficient starting circuit for switching power supply by providing a time constant circuit and two switching circuits, and driving two switching circuits sequentially through utilization of the charging voltage for the time constant circuit thus starting the power supply. CONSTITUTION:Upon throw-in of a power supply, terminal voltage of a smoothing capacitor 5 increases to conduct a Zener diode 862 so as to charge a capacitor 863. Charged voltage of the capacitor 863 is applied onto a first switching circuit 87 thus conducting a Zener diode 872 and turning a transistor 873 ON. Consequently, the transistor 881 in a second switching circuit 88 is turned ON and the charged voltage of the capacitor 863 is applied onto a control circuit 9 thus starting operation thereof. A transistor 881 is self held through the transistor 873 thus finishing starting operation. By such arrangement, a small starting circuit having low power consumption and producing a large current pulse can be obtained.

Title: Musical tone controller for electronic musical instrument
Inventor: KIKUMOTO TADAO
IPC: G10H1/053
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to exactly by a change the pitch currently under sound production to a target value by a simple operation by adopting a constitution to execute the control to invalidate the pitch change control in manual operation when an instruction to change the pitch is given and to change the pitch of the musical tones currently under the sound production to a target value. SOLUTION: The control panel of an electronic musical instrument 4 has a keyboard device 41, a pitch bender 42, etc. The pitch can be changed in compliance with the operator's intention according to the manipulated variable of the pitch bender 42. If the pitch of the musical tones under the sound production at the time of a second key touch when for example, a second key is touched while a first key is held touched is assumed to be higher than the pitch (the target pitch) assigned by the second key touch, the pitch of the musical tones under the sound production changes gradually by spending the prescribed change time on the occasion of this second key touch, by which the pitch is gently converged to the target pitch.  At this time, the pitch change control by the pitch bender 42 is invalidated and the manipulated variable is neglected at the timing of the second key touch and afterward.
