Title: Key device of electronic musical instrument
Inventor: OCHI MITSUTAKA
IPC: G10H1/057
Filed: 1991-07-11
Abstract: PURPOSE:To hold a key-ON position and a key-OFF position equal by calculating a key-OFF velocity from the time difference from the OFF time of a switch part, which operates at a deeper position than the stroke of a key-ON switch, to its key-OFF operation. CONSTITUTION:For example, two make switches are used as key-ON switches and then the 1st make switch is turned ON when a key main body 1 passes a 1st make position K10; and the 2nd make switch is turned ON at the inversion position K2 of the key-ON switch by further depression and a key-ON state is entered. When the key main body 1 is further depressed, a stopper 6 abuts on an after-touch sensor 8, which outputs after-touch data. In this case, when key-OFF operation is started, the key main body 1 moves up and key-OFF velocity data are calculated from the time difference from the passage at the position K2 where the after-touch sensor outputs a constant depressing force position to the OFF operation of the 2nd make switch.

Title: Frequency-voltage converter
Inventor: KOBORI YASUNORI
IPC: H03K9/06
Filed: 1981-10-28
Abstract: PURPOSE:To easily attain frequency switching with simple constitution, by generating a sawtooth wave continuously with an input signal, and outputting a sawtooth wave signal when the repetitive number reaches a desired number. CONSTITUTION:When an FG signal is inputted via a wave shaping circuit 4, a pulse generating circuit  14 closes a gate circuit 16. In charging/discharging to a time constant circuit 15 at the same time, a sawtooth wave is repetitively  outputted to a terminal voltage V1. The number of reqetitions is counted at a  circuit 14 and when the number reaches a desired number, the circuit 16 is opened. As a result, the feedback path is closed and the voltage V1 increases up to  the saturation voltage. The voltage V1 is outputted through the circuit 16 only  when a gate signal G is H level to be a trapezoidal signal TRAP. When the control system is closed, a sampling pulse C comes to the center of slope of the  signal TRAP. In switching the count value like this manner, the control frequency can easily and accurately be switched without the increase in externally  mounted circuits.

Title: Superconductive magnetic sensor
Inventor: KIKITSU SATORU
IPC: G01R33/035
Filed: 1987-07-09
Abstract: PURPOSE:To detect the direction of a static magnetic field with high accuracy and high sensitivity, by using the second class superconductor and utilizing the longitudinal magnetic field effect thereof to detect the change of a critical current. CONSTITUTION:For example, a constant voltage source 2 is set on the basis of a characteristic A so that the current I0 flowing to the second class superconductor 1 becomes a value the same to or slightly higher than a critical current Ic. This state is a superconductive one and, when the driving force acting on a flux quantum is reduced or flux pin stopping force becomes large, said state again returns to a zero resistance state. When the direction of an external static magnetic field changes and the critical current Ic' of the second class superconductor 1 changes as shown by a characteristic B, the flowing current I0 changes to a current I0'. This current change is detected by an ammeter 3 to make it possible to detect the change in the direction of the external static magnetic field.
