Patent JP-S6248899-A (JP)
Title: Speaker
Inventor: WATANABE SHINICHI
IPC: H04R7/04
Filed: 1985-08-28
Abstract: PURPOSE:To obtain a good frequency characteristic over a wide band area by providing a continuous plural projected and recessed parts at a diaphragm and driving the node of divided vibration generated. CONSTITUTION:By press working several hexagonal pyramid shaped projected and recessed parts 11 at a diaphragm 6 made of a metal plate, a sheet of paper or a macromolecule material, the rigidity is increased. By providing a rib 12 with bending the periphery, the rigidity of the diaphragm 6 is increased and also a trembling is prevented. A voice coil bobbin 7 on which a coil 8 is wound is fixed at the node of the divided vibration generated at the diaphragm 6. Since the projected and recessed parts 11 are formed continuously, the rigidity is increased and also, the surface area of the diaphragm is widened, making larger the node circle 13 of the divided vibration. Therefore, the diaphragm is lightened and miniaturized, permitting the use of a big voice coil, and increasing the sensitivity of a speaker, and reducing the size of the diaphragm, and widening the directional characteristic of the speaker.

Title: Optical disk recording/reproducing device
Inventor: KONDO TAMON
IPC: G11B27/10
Filed: 1991-07-02
Abstract: PURPOSE:To improve the accuracy of a program searching by a conventional reproducing function. CONSTITUTION:After the recording of program information is over and TOC information stored in a TOC memory 44 written in an optical disk 21, the program information on the optical disk 21 is reproduced in a temporary stop reproducing state and an accurate program starting position is confirmed by using temporary TOC information on the TOC memory 44. When indexing information on the TOC memory 44 is not proper for the confirmed accurate program starting position, the indexing information on the TOC memory 44 is rectified in accordance with this accurate program starting position information. When the confirmation and rectification of the indexing information on the TOC memory 44 is completed, the indexing information on the TOC memory 4r is written in the optical disk 2. Thus, at the time of reproducing, an extremely accurate program searching is operated by only specifying a track number, that is, a music number in accordance with the indexing information.

A1 alloy powder respectively. CONSTITUTION:For example, at the time of subjecting a piston made of an A1 alloy for an internal combustion engine to hot comacting, the green compact 7 of A1 alloy powder is filled into a die for compacting, and the compacting die for forming the outer face or inner face of a compacted part on the green compact 7 is pressed against the green compact 7. Then, the green compact 7 is allowed to plastically flow and is subjected to hot compacting to form its shape into a prescribed one. In this compacting method, the main body part 7B of the green compact 7 is formed of heat resistant A1 alloy powder and the retaining part 7A in which the plastic flow is hard to occur is formed of low m.p. A1 alloy powder in which a solid phase and a liq. phase are coexistent at a hot compacting temp. to form its state into a half-melted one. In this way, the low m.p. A1 alloy powder is half-melted and works as a binder at the time of the hot compacting, and nonsoften heat resistant A1 alloy powder is joined and integrated with each other to secure its strength.

Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To minimize increment in traffic by determining the transmission/non- transmission of a communication packet and the communication format of each communication packet state to be communicated, on the basis of port information corresponding to a port for transmitting the communication packet. SOLUTION: When a receiving port number '2' and a transmitting port number '3' are different from each other, although a switching control part 4-2 transfers a unicast packet to a transmitting port 4-15, if when the receiving port number and the transmitting port number are equal, a received packet is discarded in a switching hub 4-1. When a unicast packet is received by a port 4-13 e.g. a switching control part 4-2 retrieves an address table from a transmitted MAC address included in the packet, determines a transmitting port number and then transfers the packet to the transmitting port, independently of matching/non-matching between the receiving port number and the transmitting port number.

Title: Manufacture of graphite powder for lithium ion secondary battery negative electrode
Inventor: FUJIWARA TORU
IPC: H01M4/587
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To enhance the crystallinity of graphite and increase the discharge capacity of a negative electrode by conducting a crushing process before and/or after a carbonization process under a non-oxidizing atmosphere. SOLUTION: A graphite powder is produced through processes of carbonization, graphitization and crushing using a mesophase as a raw material. At this time, the crushing is conducted before and/or after the carbonization process under a non-oxidizing atmosphere and is not conducted after the graphitization. When the crushing is conducted after the graphitization, the graphite powder having a significantly large specific surface area is obtained, thus the charge/ discharge efficiency and the cycle lifetime of a negative electrode is shortened. Additionally, the mesophase of the raw material is preferably not subject to the surface oxidation. The time for crushing may be determined according to the fusion during the carbonization in the mesophase of the raw material. That is, when the fusion during the carbonization is great, the mesophase is crushed after the carbonization.  When no or a little fusion is observed, the mesophase is better to be crushed before the carbonization.
