Title: Crank mechanism provided with differential gear device
Inventor: NEMOTO ISAMU
IPC: F02B41/04
Filed: 1981-02-16
Abstract: PURPOSE:To convert almost all of composite pressure acting on the piston face into the rotation force of a crank by combining a differential gear device as a device to change the force of the circumferential direction of a crank arm with the crank mechanism. CONSTITUTION:When a drive vehicle A turns around a sun gear D fixed by a connecting bar l, the tangential force component of an arm r becomes a gear facial pressure to the sun gear D to turn the sun gear D in the same direction as the arm r. Then, the radial force component of the arm r by connecting bar l becomes a gear facial pressure to another sun gear B. By this, both the sun gears B and D turn in the same direction. If the number of teeth of the sun gear B is equalized with that of the gear D, the angular velocities of both the gears B and D are equalized. Thus, when these are connected by a link F, even the radial force component of the arm r can be returned to an output shaft O3, and therefore, all the pressure acting on the piston P can be taken out of the shaft O3.

Title: Semiconductor memory device
Inventor: SHINOHARA ISAO
IPC: G11C11/413
Filed: 1988-01-29
Abstract: PURPOSE:To require no control circuit nor control signal at the time of using a redundant circuit and to simplify a circuit constitution by rewriting a decoder only by disconnecting a fuse. CONSTITUTION:When the fuse of a flip flop C is not disconnected, a transistor inputted to a gate via the fuse from a contact N2 is turned on and the gate of the transistor having the contact N2 as a drain and a GND as a source is brought to a low level. Accordingly, the contact N2 maintains the state of a high level to run the transistor of a transfer for connecting a signal phiB to a word line WL on and charge a word line selected by an ordinary decoder. When the fuse of flip flop C is disconnected, since the transistor inputted to the gate via the fuse from the contact N2 is constantly turned off, the contact N2 is defined to be the drain and the GND to be the source. The transistor is constantly turned on to bring the contact N2 to the low level and turn the decoder off. Thereby, the circuit is simplified.

Title: Musical sound synthesizing device and synthesizing algorithm derivation method
Inventor: NAKANISHI MASAHIRO
IPC: G10H7/08
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To provide a musical sound synthesizing device enabling even a person incapable of performing an actual wind instrument to have pseudo-experience with the substantial performance of a wind instrument. SOLUTION: This device has a processor 103 for generating approximately equal time waveforms in a wind instrument sound via the solution of a nonlinear differential equation derived from the addition of a forced vibration term such as a voice to a synthesizing algorithm based on the sound production mechanism of a wind instrument, and a microphone 101 for inputting a voice signal to the processor 103 as the forced vibration term of the differential equation. Also, the processor 103 generates a desired musical sound on the basis of each information (e.g. pitch, level and waveform) of the voice signal. In this case, a tone quality change peculiar to the wind instrument can be realized simply by controlling a voice generation mode.  For expressing a growl (a trembling phoneme appearing at the rise of a sound), for example, a trembling sound is pronounced directly by a voice, and the input of a voice in the 'ta'-column or the 'ka'-column is simply required for expressing tanging.
