Title: Optical head device
Inventor: YASUZAWA TAKUYA
IPC: G11B11/10
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To provide an optical head device capable of compensating an aberra tion caused in transmitting light through a substrate, to which a birefringence diffraction grating layer is applied and preventing sensitivity of a focus error signal from lowering. SOLUTION: Light emitted from a semiconductor laser 1 is incident on a triangular prism 19, and is reflected by a polarization beam splitter layer formed between the substrate 9 and the triangular prism 19 and collimated by a collimator lens 3 and then converged on an optical disk 63 by a convergent lens 5. Return light from the optical disk 63 is advanced in the opposite direction on the same optical path, and is again incident on the triangular prism 19, and a part of an original polarized component is transmitted through the polarization beam splitter layer 20, while a polarized component generated by the Kerr effect is almost transmitted.  The light transmitted through the polarization beam splitter layer 20 is reflected and diffracted by the birefringence diffraction grating layer 70 having an aberration compensating function, and an aberration caused by transmission through the substrate 9 is compensated to +1st order diffracted light, and afterward, the light is received by a photodetector 71.

Patent JP-S62161298-A (JP)
Title: Digital remote controller
Inventor: HONGO KATSUNOBU
IPC: H04Q9/16
Filed: 1986-01-10
Abstract: PURPOSE:To reduce interference between remote control systems by transmitting an intermediate pulse after transmitting either custom code or instruction code, and then transmitting either the instruction code or custom code. CONSTITUTION:When a remote control signal is transmitted by transmitting side, custom code 33 of 7 bits is transmitted, and then an intermediate pulse 35 and instruction code 34 of 8 bits are transmitted in order. The receiving side recognizes code received before the intermediate pulse 35 as custom code 33, and recognizes code received thereafter as instruction code 34. When the custom code 33 is the code designated to the receiving side, the receiving side interprets the instruction code 34, and executes the instruction. The same effect can be obtained even if the order is made to instruction code, intermediate pulse, custom code. Thus, interference between remote control systems can be reduced, and many independent remote control systems can be made.
