IPC: H04L12/28
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To effectively utilize limited buffer size and to reduce buffer capacity by dividing a storage means such as a buffer, etc., capable of temporarily store the transmission and receiving data into two areas, i.e., the transmission and receiving buffers and changing dynamically these two areas depending on the transmitting and receiving data sizes. SOLUTION: A buffer 11 is divided into two areas, i.e., a transmission buffer 12 which serves as a transmitting data storage area to store the transmitting data and a receiving buffer 13 which serves as a receiving data storage area to store the receiving data respectively. A buffer control part 14 sets and manages the areas of both buffers 12 and 13 of the buffer 11 contained in a controller 10. Then the size of every buffer is changed dynamically, as necessary. If the size of the buffer 13 is deficient in a reception mode, the size of the receiving data is recognized and stored. Then the size of the buffer 13 is changed according to the size of the stored receiving data.

IPC: C01B25/32
Filed: 1992-12-18
Abstract: PURPOSE:To continuously produce natural hydroxyapatite having a uniform grain diameter or crystallinity by baking a livestock bone treated in an autoclave in a fluid idized bed baking furnace capable of controlling the raw material and air feed rates at a specific temperature. CONSTITUTION:The method for producing natural hydroxyapatite is to use a livestock bone, produced in a processing and treating step for an animal product and treated in an autoclave as a raw material and spontaneously burn the raw material in a fluidized bed baking furnace capable of controlling the feed rate of the raw material and feed rate of air for combustion and fluidization at a constant temperature of 600-900 deg.C. Since the resultant powdery hydroxyapatite contains trace amounts of various elements derived from the nature, the hydroxyapatite obtained from the first recovery port can be used as a mineral supplying agent, a drug delivery system carrier or a bioceramic raw material having high biocompatibility and the hydroxyapatite obtained from the second recovery port can be used as an adsorbent for organic substances or a removing material for toxic ions due to its extremely large surface area.

Title: Sealing device
Inventor: KAMEMURA MAKOTO
IPC: F16J15/3252
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To maintain sealability and slidability in good balance by positioning a treated area and an untreated area alternately with surface hardness increased by radiation exposure at the lip part of a seal lip formed out of a rubber-like elastic body brought into contact with the sliding surface of a counterpart. SOLUTION: This sealing device 1 is provided with a treated area 11 and an untreated area 12 alternately with surface hardness increased by radiation exposure positioned at the lip part 8a of a seal lip 6 formed of a rubber-like elastic body brought into contact with the sliding surface 3a of a counterpart 3. The treated area 11 with surface hardness increased by the radiation of the lip part 8a of the seal lip 6 suppresses the deformation of a seal lip 6 and an excessive rise in tense force caused by the untreated area 12. It is thus possible to suppress the deformation of the lip almost uniformly, maintain the tense force of the untreated area, improve sealability during sliding, and reduce sliding resistance.

Inventor: LEE BIN
IPC: H04W88/08
Filed: 1999-12-22
Abstract: PROBLEM TO BE SOLVED: To improve error bit performance and to increase a system capacity by providing plural continuous detection stages and making the respective detection stages process reception signals and supply the gradually improving estimated values of traffic signals. SOLUTION: A detector/decoder part 750 is provided with a first stage 780 and a second stage 800 connected to each other and is connected to a receiver/ demodulator part 705. In this case, when one set of 6144 pieces of demodulation samples 730 are inputted to a block buffer 740, the block buffer 740 simultaneously sends one block of the demodulation samples 730, normally reception samples 730, to the first stage. The first stage 780 is simply provided with a non-coherent receiver 790 and the receiver 790 converts the block of the demodulation samples 730 to 192 pieces of traffic data bits 80, that are a first estimated value. The traffic data bits 80 are supplied from the first stage 780 to the second stage 800. By such a procedure, the error bit performance is improved and the system capacity is increased.

Title: Door for suspended cupboard
Inventor: TAKEUCHI SHINICHI
IPC: A47B77/04
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a means which enables mounting of a clock having a large dial or a dial plate to an existing suspended cupboard by a simple operation so as not to hinder the work in a kitchen. SOLUTION: When a clock 12 is mounted to a suspended cupboard, the clock 12 is fixedly mounted integrally to a location at which a face or a dial plate 23 of the clock is set by observing the front surface of a door 13 of the suspended cupboard. Thus the clock 12 having a large face or a dial plate can be mounted to the suspended cupboard without hindering the work in a kitchen. Since the door 13 is openably connected to the body of the cupboard through a hinge, an existing door is dismounted from the hinge and a new door 13, on which a large face or a dial plate 23 is fixed, is mounted to the cupboard, whereby the clock 12 can be easily mounted to the existing cupboard.

Title: Point to multi-point transmission network
Inventor: GRAMMEL GERT
IPC: H04N7/10
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To allocate a transmission channel. SOLUTION: In the network, n-pieces of transmission channels can freely access each of sub-centers 11-18 and the previously defined allocation of the group of the transmission channels to the previously defined sub-centers is prevented from being executed. The allocation of the transmission channels to the sub-centers 11-18 is executed in a simple form by inspecting the occupation state of the transmission channels and allocating it when it is idle. The division of the transmission channels that can be used to the group accessed only by the specified sub-center is discarded. Thus, the flexibility of the allocation of the transmission channels that can be used becomes maximum and the use becomes optimum.

Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To improve a capacity and long-term stability and to improve the cycle characteristic of a secondary battery by containing cyclic sulphite in an organic solvent. SOLUTION: This organic solvent contains the compound expressed by the formula, where R1, R2 independently indicate the bivalent hydrocarbon group with the carbon number 1-4, and X indicates O, NR3, PR4 or R5P=O. R3, R4 and R5 are independently hydrogen atom or the hydrocarbon group with the carbon number 1-4. As a practical example of cycle sulphite, erythritan sulphite is used. The content of the cyclic sulphite in the solvent is preferably set to 0.1-30 wt.%. If the content is below the lower limit, no sufficient protective film is formed. If the content exceeds the upper limit, the viscosity of an electrolyte is increased, the electric conductivity is lowered, and battery performance is deteriorated. Inorganic Li salt such as LiClO4 or fluorine-containing organic Li salt such as LiCF3SO3 is preferably used for a solute.
