Title: Optical censer
Inventor: KUMABE KENJI
IPC: H01L27/146
Filed: 1986-05-30
Abstract: PURPOSE:To accelerate the falling speed of optical response regardless of the lower intensity of illumination by a method wherein in an optical senser using the optoelectric conduction effect of an amorphous thin film containing hydrogen and other additives, the composition ratio of hydrogen or other additives contained in the thin film is varied in the film thickness direction. CONSTITUTION:The forbidden band width in an element is fluctuated in the film thickness direction by means of fluctuating the composition ratio of hydrogen or other additive in the hydrogenated silicon thin film to form a region with narrow forbidden width into layer. 0.2 Torr of silane gas is led into a plasma CVD device to decompose silane by high frequency discharge so that hydrogenated amorphous silicon may be deposited on a glass substrate. 10-30% of hydrogen is to be contained in the deposited amorphous silicon. The composition ratio of such a hydrogen depend on the silane gas pressure, high frequency power and substrate temperature. The thin film with the forbidden band distributed in the film thickness direction can be formed by fluctuating the temperature of substrate during the process of growing the thin film by depositing amorphous silicon.

Title: Tracking error signal generation device for optical device
Inventor: KUME HIDEHIRO
IPC: G11B7/095
Filed: 1990-05-18
Abstract: PURPOSE:To eliminate a DC offset signal with the aid of a simple circuit by executing subtraction after multiplying the offset signal of a tracking error signal being the difference output of first and second peak value detectors by a specified coefficient. CONSTITUTION:The tracking error signal is generated by detecting the peak value of a detection signal from a photodetector 11 with the aid of the peak value detectors 13A and 13B, supplying it to subtracters 15A and 15B, subtracting the envelope level of an RF signal, eliminating a DC offset compo nent generated to the output side of the subtracter and supplying it to a third subtracter 16. Then, by setting the level of the peak value subtracted from the envelope of the RF signal to 0.5 - 0.8 of the ratio R1/R2 of the resistances R1 and R2, the DC component of the error signal can be effectively eliminated. Thus, the DC offset signal generated caused by the deviation of the optical axis of an objective lens is eliminated by the simple circuit.

Title: Path bypassing method and system therefor
Inventor: SUZUKI MINORU
IPC: H04L47/76
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To enable a network administrator to select a path to be bypassed in advance by securing a band needed for bypassing for a bypass for a path to be bypassed at the time of a line disconnection. SOLUTION: Paths 203 and 204 are registered for a line 110. An indication for disconnecting those two paths is sent to a path disconnection indication transmission and reception 16. On receiving this, the transmission and reception part 16 sends the path disconnection indication for paths 203 and 204 to a node 102 as one terminal of the path to be disconnected through the line 111 as a connection line to the node 102. A transmission and reception part 16 of the node 102 having received the indication informs a path switching execution part 15 of that. The path switching execution part 15 on receiving this indication disconnects the paths 203 and 204. Consequently, the line 122 has 200 made free as a band for two paths, so paths 300 and 301 can pass.

Title: Hot broadside screw down rolling method for slab
Inventor: ICHIKAWA SHIROU
IPC: B21B1/02
Filed: 1981-08-14
Abstract: PURPOSE:To prevent the generation of dragging-down flaws on a slab and to make broadside screw-down rolling of good efficiency possible by increasing the diameter of box caliber rolls and decreasing the peripheral speed ratio between the inner side surfaces of the calibers and the bottom parts of the calibers with which the dogbone parts contact. CONSTITUTION:The generation of dragging-down flaws on a slab 1 by broadside screwing-down can be prevented by maintaining the peripheral speed ratio between the inner side of the calibers and the bottom parts of the calibers where the bulging parts on the side end parts of a slab 1 formed by box caliber rolls 9 for broadside screw-down rolling of the slab 1 contact within a range not exceeding 1.3. In order to obtain said peripheral speed ratio of the calibers, the diameter of the rolls is made sufficiently large. The use of sufficiently deep calibers is made possible by the absence of the dragging-down flaws and efficiency is improved by the increased total rate of continuous broadside rolling reduction. Hydraulic rolling is made possible and stable biting is obtained by the decrease angle of bite on account of the larger diameter of the rolls, and the rolling reduction per pass is increased.
