IPC: C07D213/68
Filed: 1990-11-29
Abstract: PURPOSE:To improve nonlinearity and generation efficiency of harmonic waves by coupling an electron donating functional group and electron accepting functional group to the both ends of pi-electron of benzene ring or the like of an org. nonlinear optical material expressed by specified formula. CONSTITUTION:An electron donating functional group and electron accepting functional group are made to couple with both ends of pi-electron of benzene ring or the like of an org. nonlinear optical material expressed by formula I or II. In formulae, R1 is selected from hydrogen, halogen atom, alkyl groups, R3, R4 are selected from hydrogen or methyl group. For example, the compd. of the formula I having hydrogen atoms as R3 and R4, two pi-electrons make an angle of 109.5 degree to rigidly couple with the methylene carbon. This compd. has large dipole moment in the direction shown by an arrow in the figure. Thereby, nonlinearity and generation efficiency of harmonic waves can be improved.

Filed: 1988-12-29
Abstract: PURPOSE:To attach an open/close coil spring to a cassette holder main body simultaneously when the one edge of the temporarily fixed spring is detached from a cabinet by providing a guide rib having a certain inclination at the cassette holder main body. CONSTITUTION:An open/close coil spring 4 is temporarily fixed, and the cassette holder main body is attached. The through hole of the cassette holder main body provided at a leg part 7 is inserted to a rotation axis 2, when the cassette holder main body is rotated in an arrow D direction, one edge 4b of the open/ close coil spring 4 is moved in an arrow E direction due to the inclination of a guide rib 8, and it is inserted between the leg part 7 and a rib 9 of the cassette holder main body. Consequently the force of the open/close coil spring 4 is applied to the cassette holder main body, and spring force is operated in the direction to open the cassette holder main body. Thus, as soon as one edge of the open/close coil spring temporarily fixed at the cabinet is detached from the cabinet, it can be loaded on the cassette holder main body by the guide ring 8.

Title: Land/groove position detection system and detection
Inventor: YAMANAKA YUTAKA
IPC: G11B7/131
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To detect positions of a land and a groove even when a guide groove width and a width between guide grooves are the same by bringing a convergent spot into a slightly defocusing state and detecting the land and the groove in a difference between their reflected light distributions with a change in a light receiving quantity of a partial reflected beam. SOLUTION: A photodetector of, for instance, a bisected type is used to receive light in the vicinity of the center of the beam. That is, the bisected photodetector 6 has a narrower width than the light beam to be received in the direction orthogonal to a track guide groove, and consists of a light receiving part bisected in the direction orthogonal to the track guide groove. Then, a track error signal can be detected from a difference signal (an output of a subtractor 10) between individual output signals of the bisected photodetector 6. On the other hand, a land/groove signal is obtained from an output signal of an adder 11 by making the slightly deforming state of the spot on the optical disk.
