Title: Exposure method
Inventor: WATANABE KATSURA
IPC: H01L21/30
Filed: 1986-01-27
Abstract: PURPOSE:To process a photo-resist to a stopped shape as an excellent shape by partially changing the quantity of exposure to the photo-resist by using the same mask. CONSTITUTION:A photo-resist 2 is formed to the surface of a semiconductor substrate 1, a mask 5 consisting of a light nontransmission material is arranged just above the resist 2, and the surface is exposed by light energy L. When the mask 5 is exposed at a position shown in a solid line first, the mask 5 is moved to a position shown in a dotted line partially overlapping to the position of the solid line, and exposed again. An exposed section is changed into a removing section 2g under the state in which a stepped section 2f is shaped in the resist 2 through development. A stepped section 1d corresponding top the stepped section 2f of the resist 2 is formed around a projecting section 1a shaped to the substrate 1 through etching.

Title: Packet processing system for inter-network connecting device
Inventor: HATTORI YOICHI
Filed: 1985-01-31
Abstract: PURPOSE:To decrease the average waiting time by using a means to decide whether both packets are equal to each other or not and then disuses one of both equal packets if exists with the other left. CONSTITUTION:A packet receiving part 3 receives packets from a network 1 and stores them successively to a packet receiving buffer 4. A received packet comparison processing part 12 receives the information on reception of packets and check whether or not a received packet exists in the buffer 4. If both packets exist, one of these two packets is disused with the other left as it is. A control part 11 extracts successively the packets stored in the buffer 4 in an FIFO system and produces the transmission packets through the protocol conversion, etc. and stores them in a packet transmitting buffer 5. Then the part 11 informs the storage of the transmission packets to the part 13.

Title: Virtual path switching control method for atm network
Inventor: TAKATORI MASAHIRO
IPC: H04L45/243
Filed: 1995-02-02
Abstract: PURPOSE: To reduce an influence upon the other traffics and to quickly switch plural virtual path(VP) by generating a switching control OAM cell with a long period in the case of the absence of a switching request and generating it with a short period in the case of the presence of the switching request. CONSTITUTION: The switching control OAM cell is generated with a long period T1 at the time of the absence of the switching request in a node (normally), and a period T2 of switching request generation is made shorter than this period T1. Thus, the switching control OAM cell is used to ensure the coincidence between current paths of two transmission and reception leads even if another information cell or the like doesn't exist. Further, current system/ standby system VP switching control is quickly performed at the time of the presence of the switching request. The period of OAM cell generation is varied in this manner to reduce the influence upon traffics.

Title: Solar battery, its manufacture and manufacturing device
Inventor: HAMAMOTO SATORU
IPC: H01L31/04
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To remove a surface part which is mechanically damaged and to form a projecting/recessed structure for confining light with a one-time etching by executing special etching on a silicon substrate having a rough face sliced by mechanical processing. SOLUTION: For removing a first surface part 7 of a silicon substrate 1, sodium silicate is dissolved in water and is subjected to etching by the use of an aqueous solution, for example. Sodium silicate is used for etching and dissociation to ions does not proceed completely in sodium silicate. This largely contributes not only to the deceleration of etching speed but also to the form of an etched surface, and a desired ruggedness form can be obtained. The mechanically damaged surface part can be removed, and a ruggedness structure which is effective for confining light can be formed with one etching only by the etching, namely, by a primary etching process.
