Title: Nonlinear optical device
Inventor: SASAKI KEISUKE
IPC: G02B6/12
Filed: 1984-05-28
Abstract: PURPOSE:To enable phase matching by a simple method using a material which is incapable of angle matching by superposing a thin film waveguide of an optically nonlinear material on a thin film optical waveguide and giving a tapered change of thickness to both or one of the waveguides. CONSTITUTION:The wave-guided light through a waveguide 2 in the perpendicular direction and through a gradient formed by a light input and output coupler prism 3A, 3B mounted on a thin film optical waveguide 2 with a slant thickness gradient on a flat substrate 1 is mode-coupled with an optical waveguide 4 of a nonlinear optical crystal of 2-methyl-4-nitroaniline(MNA), etc. having higher refractive index than the waveguide 2 between the coupler prism 3A, 3B, and converted to the second light harmonic light in the waveguide 4 and mode-coupled to the original waveguide again, and outputted together with the fundamental wave light from the prism 3B. The second light harmonic light is isolated from the outputted light. When the incident light 5 is shifted so as to result highest received light intensity, thus, phase matching of the light is possible simply by using MNA, etc. which is incapable of angle matching.

Title: Multiplex transmission system
Inventor: MUTO MAKOTO
IPC: H04L12/40
Filed: 1989-04-28
Abstract: PURPOSE:To simply identify an address of a transmission node even when no transmission node address is included in a frame by adding a reception confirming signal able to identify the transmission node to a data and sending the resulting data. CONSTITUTION:A reception acknowledge field (ACK field) assigned corresponding to each node for each bit is provided in succession to a frame F and one bit is split into 3 phases as a transmission code. Then a bit location being one logic such as logic 1 is used as a bit location corresponding to a reception node address, and a bit location being other logic such as logic 0 is used as a bit location corresponding to an address without any node, and a bit location of a code other than logics corresponds to a transmission address. Thus, when the code other than the two logics is identified, the address of the transmission node is detected. Thus, even when an address of its own station of a caller node is not included in the frame F, the address of the caller node is simply identified.

Title: Pulse peak detector
Inventor: KUSANO TAIZO
IPC: G11B20/10
Filed: 1989-04-27
Abstract: PURPOSE:To obtain the binarizing signal having a small error by ANDing between a gate pulse and a pulse, which is generated in a zero cross point in the twice differentiating waveform of a reproduced signal waveform, by a gate means. CONSTITUTION:A level clamp area is provided in a recording medium and comparatively long '0' data and '1' data are written at the time of recording. At the time of reproducing, level difference between the '0' data and '1' data in this level clamp area is detected as a first level by a detecting means 10. This detected level is a level corresponding to a real writing condition. In a level generating means 11, a second level is generated by multiplying this first level and a fixed gain. This second level is a slice level and made variable corresponding to the real writing condition. Thus, a peak pulse is generated only in a peak point in the waveform of a reproduced signal and binarization can be executed by the optimum slice level corresponding to the level difference between the '0' data and '1' data. Then, the error is decreased.
