Inventor: ITSUGAYA KINJI
IPC: H04L12/28
Filed: 1993-12-28
Abstract: PURPOSE:To obtain the stable traffic state by providing an STM communication line and using an STM cell processing signal to implement alternative transfer on the occurrence of a fault. CONSTITUTION:When an ATM communication line 4, or 6, or an ATM communication equipment 6 is faulty, the communication between LAn terminal equipments 1, 2 is made by allowing an ATM communication equipment 3 or 7 to convert transmission information into an STM cell processing signal and it is sent to an STM communication line 8. The communication equipment 7 or 3 receiving the STM cell processing signal applies de-cell processing to the signal and provides an output to the terminal equipment 2 or 1. Thus, the terminal equipments 1, 2 are communicated through the STM communication line 8 being a bypass. Furthermore, when the lien 4 is faulty, the information from the terminal equipment 1 to the communication equipment 5 is delivered through the communication line 8 being the bypass and the usual communication line 6. Furthermore, the information from the terminal equipment 2 to the communication equipment 5 is delivered through the communication lines 8, 4 when the line 6 is faulty. Moreover, a private line is used normally for the STM communication line 8.

Title: Fluidized bed with inclined reaction pipe
Inventor: KATO MORITAKA
IPC: B01J8/24
Filed: 1987-12-28
Abstract: PURPOSE:To very easily perform construction while a short pass of flow in a reaction pipe is prevented by mounting the reaction pipe in a specified angle- inclined condition to a perpendicular direction in a fluidized bed body. CONSTITUTION:A facility 12 is composed of a free board part 13 and a fluidized bed body 14. In the fluidized bed body 14 reaction pipe groups 15 composed of 95 reaction pipes 1 are inserted at an inclined angle of 15-60 deg.C to the perpendicular direction to the fluidized bed body 14. Prescribed catalysers are filled into each reaction pipe 1. Since dead zones which indicate a space made on the upper part of the catalysers in each reaction pipe 1 are very small in number, the facility 12 is applied as a piston controlling type reactor. Further, since each reaction pipe is inclined at a most suitable angle, a reaction area which exists in the fluidized bed body 14 is larger than those in the case of horizontal and vertical pipes. Thus, the improvement of a heating surface area at the time of reaction can be achieved. Further, gathering of bubbles is lessened in the fluidized bed body 14 and stable operation can be performed.

Title: Optical pickup
Inventor: NAGASHIMA KENJI
IPC: G11B7/12
Filed: 1988-12-29
Abstract: PURPOSE:To eliminate the jitter and level decrease of a regenerative signal caused by an optical axis dislocation by using a mask which extends the shape of the spot of laser beams which irradiates an optical disk in a direction orthogonal to the track scanning direction of the laser beams.

Filed: 1990-11-28
Abstract: PURPOSE:To surely stop the flow of solder material by forming a plurality of parallel or crossed grooves for outflow prevention of solder material at the surface extremely near to the root of the die pad part of a support bar. CONSTITUTION:Plating layers 6 are formed at the die-pad part 2 of a lead frame 1 and in the vicinity of the die-pad part 2 of a support bar 3, which connects the die-pad part 2, and then grooves 4 for outflow prevention of solder material 7 are formed at the surface near the root of the die-pad part 2. As a result, the plated metal at the groove processed part is excluded, and also the plating remaining part, left at the plane between the crossed grooves, is more excellent in the wettability to the solder material 7, which has fused and diffused, than the groove parts 4, so the solder material becomes easy to stand at the plane parts between grooves, being caught there. Hereby, the flow of the solder material can be stopped surely.

Filed: 1987-12-28
Abstract: PURPOSE:To suppress the deterioration of end faces of a resonator and improve the durability of an element, by increasing the width of a groove passing through an optical absorbing layer in the vicinity of at least one of the end faces of the resonator and widening the width of a stripe in an optical waveguide. CONSTITUTION:A clad layer 12, an active layer 13, and a clad layer 14 are laminated in order. Respective current bottleneck layers 15 which act as optical absorption layers are laminated at each side part in the lateral direction of the clad layer 14 and a through groove is formed in the shape of a stripe. As the current bottleneck layers 15 have through grooves where widths of the through groove are different at parts in the vicinity of respective end faces of a resonator and at a center part of it, the stripe is formed in such a way that it is wide at the parts near each end part and becomes narrow at the center part. The optical waveguide becomes wide in the width direction near the end faces of the resonator and then, the quantity of light which is absorbed by the current bottleneck layers 15 decreases and the quantity of heat generated due to optical absorption decreases. At the center part, the width in the direction of the optical waveguide becomes small and then, even though the laser oscillate with a high output power, a stable foundamental traverse mode is obtained.
