Title: Optical kerr waveguide
Inventor: MORIOKA TOSHIO
IPC: G02B6/12
Filed: 1989-03-10
Abstract: PURPOSE:To allow the specified change in the phase of an optical Kerr waveform and to prevent the generation of crosstalks by forming the optical Kerr waveguide of an optical Kerr medium satisfying specific conditions. CONSTITUTION:The optical Kerr medium includes the material which satisfies tauL>=2DELTAt0 with respect to the pulse width t0 of control light 3 when the refractive index length is designated as L and the group delay difference between signal light 2 and the control light 3 as tau. Since the group delay difference of the control light 3 and the signal light 2 is large, the control light 3 eventually sweeps the signal light 2 in the optical Kerr waveguide 1. The part swept at this time acts as an optical Kerr shutter and changes the phase of the signal light 2. The phase change of this time is the specified value determined by the energy of the control light 3 and the rectangular optical Kerr waveform is obtd. The optical switching without having the crosstalks is executed in this way even if there is a jitter between the signal light 2 pulses and the control light 3 pulses.

An ''IRP'' bit is set into the code OC, and it is judged with this ''IRP'' bit and the result of the DDA operation whether the interruption decision processing is carried out or not. When the interruption conditions are satisfied, this information is given to a host CPU. At the same time, the operator where the interruption conditions are satisfied is stored. This improves the response performance and reduces the load of the host computer.

Filed: 1984-03-29
Abstract: PURPOSE:To reduce the capacity of a control system for search function and also to attain a satisfactory searching action, by adding newly the time sectioning information to the search function. CONSTITUTION:When a new disk is loaded, a control circuit 201 gives command to a disk motor 204, a pickup feed motor 205 and a servo circuit 209 respectively via an external control circuit 203 and reproduces the TOC data on a disk 206. When a searching action is designated, the time sectioning information is fetched newly as a standard to know the position of a desired address when a pickup 207 is moved up to the desired address.

Filed: 1994-03-30
Abstract: PURPOSE:To eliminate the generation of the warp of a substrate and to enhance the reliability of a bump connection part by a structure wherein a flat boardlike cover is supported by a pillar so as not to come into contact with a semiconductor chip which is flip-chip-mounted on a board. CONSTITUTION:A semiconductor chip 3 is flip-chip-mounted on a glass epoxy board 1 by bumps 5. Then, a cover-fixing pillar part 7 for an aluminum cover 6 is attached to the board 1 by an adhesive 8, and the cover-fixing pillar part 7 is installed in the center of the board 1. Thereby, a stress generated due to the difference in a coefficient of thermal expansion between the aluminum cover 6 and the board 1 can be reduced to a minimum. Consequently, the warp of the board due to the hardening and contraction in the curing operation of a cover resin is not generated, a stress is not applied to bump connection parts, and the reliability of a connection is enhanced. In addition, since the surface of the cover 6 is flat, a module can be sucked easily by a mounting machine when it is mounted on a motherboard, and it can be mounted precisely.
