Title: Accoustic device
Inventor: KASAI JIYUNICHI
IPC: H04S3/00
Filed: 1984-01-12
Abstract: PURPOSE:To obtain an axial localization of a sound image by providing dedicated speakers for each channel and an auxiliary speaker which reproduces synthesized signals of a mixer to be output/controlled according to the coincidence in a frequency band whose plural channel signals are separated. CONSTITUTION:An output of a stereo source 1 is supplied to dedicated speakers 3 and 4 for right and left channels through a stereo main amplifier 2, and at the same time is supplied to right and left channel dividers 9 and 10. The dividers 9 and 10 divide the corresponding channel signals into high, intermediate, and low frequency ranges and input such frequency ranges in high, intermediate, and low frequency range mixers 11a-c and high intermediate, and low frequency range comparators 12a-c. The comparators 12a-c compare respective channel signals in the relevent frequency bands to output signals the proportional coincidence in the mixers 11a-c. The outputs of the mixers 11a-c which are increased or decreased proportional to coincidence are synthesized by the overall band mixer 13, and are supplied to the auxiliary speaker 8 installed in the middle of the speakers 3 and 4 through a main amplifier 7, thus the localization an axial sound image is executed.

Title: Focus detector of optical pickup
Inventor: KANOU TOSHIO
IPC: G11B7/09
Filed: 1982-01-13
Abstract: PURPOSE:To increase the detecting sensitivity, by forming a reflecting surface of a critical angle reflecting prism to which a reflected light is made incident from a recording surface with two slanted surfaces. CONSTITUTION:The light emitted from a light source 1 of a laser, etc. is turned into a circular polarized beam through a mask 2, a condenser lens 3, a polarizing prism 4 and lambda/4 plate 5 and then condensed on a disk surface 12 through an objective lens 6. The reflected light travels backward to be reflected by the prism 4 and is made incident at a critical angle to surfaces 8 and 9 of a focus detecting prism 15 which are inclined slightly to each other. This reflected light is made incident to photosensors 10 and 11 to obtain a focusing signal. The incident luminous fluxes to the surfaces 8 and 9 are not parallel to each other, and therefore the intensity of one of surfaces 8 and 9 decreases if the intensity of the other side increases owing to an out-of-focus state. As a result, the detecting intensity is increased.
