Title: Testing system of digital audible signal tone generator
Inventor: ASHIHARA SHIYUUICHI
IPC: G01R31/00
Filed: 1980-07-31
Abstract: PURPOSE:To simultaneously detect not only contents of an ROM but also an error of a digital signal send-out control device, by a simple constitution, by reading out a digital value of an audible tone signal which is stored in the ROM, and comparing the total number of a bit ''1'' or ''0'' with the set number. CONSTITUTION:When a minimum counting value of an up-down counter C is detected by a minimum detecting circuit HD, a counter COUNT is reset through a timing circuit TIM. As a result, a digital audible tone signal which is written in an ROM is read out through the up-counting counter C, and the total number of a bit ''1'' passing through a parallel-series converting circuit PS is counted by the counter COUNT. In the event of dissidence of this counting value and a set value of a register REG, an FF is set by an AND circuit AG2 which is opened by a maximum detecting circuit TD through the circuit TIM, and a prescribed display is executed. Accordingly, it is possible to simultaneously detect not only contents of the ROM but also an error of a digital signal send-out device such as the minimum detecting circuit or the maximum detecting circuit, by a simple constitution.

Title: Optical device
Inventor: HASHIMOTO NOBUYUKI
IPC: G11B7/135
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily change over resolution to normal- resolution or super-resolution because a phase-modulating element is controlled by an electric signal in a circular region centering an optical axis of a luminous flux focused by a focusing optical system and the other region, and independently functions in both regions, and the phase modulation value is approximately a half-wave length of the laser light or a specific value. SOLUTION: A laser beam 103 emitted from a laser beam source 101 and made into a parallel and plane wave through a collimator lens 102 passes through a phase-modulating element 104, and then, it is focused by a focusing optical system 105 to form a point image 106. The phase-modulating element 104 is controlled independently in the circular region 108 centering the optical axis 107 and the annular belt region 109 by an electric signal of an electric supply source. When the electric signal is not impressed or impressed, a relative phase difference between the laser beam 103 of a wavelength λpassing through the circular region 108 and the annular belt region 109 becomes 0 or λ/2, and does not produce or produces super-resolution.  Thus, it is possible to easily change over resolution to normal-resolution or super-resolution by the electric signal, and also cope with variations in wavelengths of the beam source.
