Title: Optical pickup
Inventor: WASHIMI SATOSHI
IPC: G11B7/09
Filed: 1982-05-31
Abstract: PURPOSE:To attain the miniaturization without deteriorating the focus error detecting sensitivity, by arranging a half mirror at a collected optical path of an optical system where a reflecting light of a light spot irradiated on a recording medium is made incident to a photodetector via a condenser lens. CONSTITUTION:The reflecting light from a disc 4 passes through an objective lens 9 and a 1/4 wavelength plate 8, enters a beam splitter 7, is reflected on a polarized plane 10 and is made incident to the condenser lens 11. The light through the condenser lens 11 is cut by about 1/2 at a knife edge 19, about a half of the remaining semi-circle enters the half mirror 16 through a 1/4 wavelength plate 15, a half of the amount of light only is reflected and returned to the beam splitter 7 through the 1/4 wavelength plate 15 and the condenser lens 11. Since this returned reflecting light is subject to polarization at the 1/4 wavelength plate 15, the light is made incident to the 1st photodetector 17 by being transmitted through the polarized plane 10 to detect the focus error. Further, the light transmitting through the half mirror 16 enters the 2nd photodetector 18 and the tracking error is detected through the detection of change in a distributing amount of light.

Title: Optical pickup
Inventor: EMOTO MASAMI
IPC: G11B7/135
Filed: 1982-06-03
Abstract: PURPOSE:To read the information recorded on an informtion track on a disk with no malfunction, by provding a reflecting surface into a critical reflecting prism. CONSTITUTION:A reflecting surface 11 is provided along the center line of a prism. Thus the luminuous fluxes existing at the side higher than an optical axis are made incident to a photodeteting part 8B through the lower side of the surface 11 if they are totally reflected in the prism. On the other hand, the luminous fluxes existing at the side lower than the optical axis are made incident to a photodetecting part 8A through the upper side of the surface 11 if they are totally reflected in the prism. Therefore, the luminous fluxes higher than the optical axis are always made incient to the detector 8B although a disk gets further away from an objective lens and the condensing point is set before a photodetector 8 or within the prism 7 when necessary. While the luminous fluxes lower than the optical axis are always made incident to the detector 8A. This eliminate the erroneous detection.

IPC: B60T8/1769
Filed: 1986-04-25
Abstract: PURPOSE:To prevent a braking force effectively from being reduced by conditioning a drive system into a direct four wheel drive when a brake device falls into an anti-lock condition. CONSTITUTION:When either of two cross piping type systems falls into an anti-lock control condition, a signal from either of logic circuits 15a or 15b is given to the OR gate 16 of a signal generating circuit 12. As a result, the OR gate 16 is turned on for obtaining a signal S3 on the output side of a timer circuit 17. Subsequently, the output signal S3 is given to actuators 13a-13c. Resultantly, a front differential gear 2a, a rear differential gear 2b, and a center differential gear 3 are locked wherein a driving system is conditioned to a direct four wheel drive. Owing to this constitution, as the braking force on a front wheel side, on which the most braking force depends, acts on a rear wheel side too, a reduction in the braking force can be effectively prevented.
