Title: Optical switching element
Inventor: MASAKI YUICHI
IPC: H01L31/10
Filed: 1986-04-23
Abstract: PURPOSE:To obtain an optical switching element provided with a transistor portion having a high ON/OFF ratio, by using for a solar cell element a photo- sensitive portion formed of an amorphous silicon layer of three layer construction in a P-I-N structure and metal electrodes formed of chrome or nichrome as the upper electrodes thereof. CONSTITUTION:When a signal light L enters a solar cell element, an electromotive force is generated in a photo sensitive portion 23. By this electromotive force generated, a channel 26A is formed in an active layer 26 of a thin film transistor portion through the intermediary of a second electrode 24 and an insulating film 25. Accordingly, this thin film transistor portion is put in the 'ON' state. When no signal light L enters, to the contrary, no electromotive force is generated in the photo sensitive portion, the Channel 26A is not formed, and therefore this transistor portion is put in the 'OFF' state. Thus, an optical switcing element is completed.

Title: Device for generating calibration signal for measuring jitter
Inventor: OWADA YASUSHI
IPC: G01R35/00
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a measurement value being measured by a jitter measurement device. SOLUTION: A Gaussian noise generation means 23 generates a Gaussian noise where a voltage distribution follows a Gauss curve. A PWM modulation means 26 uses the Gaussian noise as a modulation signal and performs a PWM modulation to a pulse with a frequency corresponding to 3T in an EFM signal. In this case, the fluctuation center value of a pulse width is matched to the 3T (cycle) in the EFM signal, thus obtaining a PWM modulation output TD. The PWM modulation output TD is used as the calibration signal of an analog jitter measuring instrument for measuring the jitter of the EFM signal of a CD player. Also, the gain of a gain-variable amplifier 24 is varied, thus setting the standard deviation of the jitter distribution of the PWM modulation output TD to an arbitrary, desired value.
