 note = {A new type of analog voltage generator is proposed and tested. An optical strip is projected upon a mirror surface cylinder with a function paper stuck on it and the reflected light is converted to voltage photoelectrically in proportion to the function curve. As a result of trials and considerations, a simple apparatus which can be put to practical use with satisfactory accuracy and reliability is produced. In this report its principle and construction are fully explained, and features of the systems are also shown as listed below. (1) Since this system can generate voltage mecanically and optically by a simple device, the utility of operation element is largely extended. (2) A photoelectrical conversion system has a wide limit of the response speed. While a unit impulse wave is imopssible to be convered directly by an analog computer, it can be easily reproduced by this generator. (3) The accuracy of the wave form obtained by the generator is about 0.5 for the original curve, and is usually sufficient for the analisis of actual events. (4) As the circuit of this system is simple and the characteristics of the phototube is very stable, the drift is quite small. From observations of the records of an X-Y recorder, hysteresis is also found to be very slight. (5) In practice, a large quantity of calculations can be easily performed by replacing function cylinders which are prepared previously after experimental data. In conclusion, these characteristics make it possible to calculate examples from elementary analysis of mecanical events in the field of engine and automobile engineering., Article, 信州大学工学部紀要 34: 35-48 (1973)},
