Patent JP-H1132027-A (JP)
Title: Method, system and receiver for determining symbol transmission format used in transmission system
Inventor: GUEMAS PHILIPPE
IPC: H04L27/38
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To recover a complex symbol which has been edited especially for an orthogonal frequency division multiplexing(OFDM) block, without the need for a reference signal and without knowing the transmission format in advance. SOLUTION: The proposed method includes a step, where a 1st sequence of a complex symbol is stored by using an acquisition time window (AW), steps 311, 312 where a correlation between the 1st sequence of the complex symbol and a 2nd sequence of a complex symbol selected by using a correlation time window (CW) at other moment is determined, and steps 330, 340, 350, 380 where a transmission format is determined by retrieving a point at which the correlation between the 1st sequence of the complex symbol and the 2nd sequence of the complex symbol is maximized. The retrieval is conducted by synchronizing the acquisition window with the received signal and selecting the 1st production by the acquisition time window while the 2nd production by the correlation time window.
Patent JP-H086763-A (JP)
Title: Partial product generating circuit
Inventor: HORI MITSURU
IPC: G06F7/533
Filed: 1994-06-23
Abstract: PURPOSE:To reduce the power consumption at the time of multiplier-fixed multiplication. CONSTITUTION:One digit Z1 of a partial product is outputted by performing logical operation by inputting a shift signal C1 obtained by performing the booth decoding of two adjacent digits Xi-1 and Xi of a multiplicand and three adjacent digits of a multiplier, an inverted signal C2, and an enable signal C3. Respective elements other than TGs 2 and 3 have CMOS structure. When an enable signal C3 is 0, a NAND 6 outputs 1, so 0 is always outputted as Zi. At this time, an AND 4 always outputs 0, so when the Ki-1 and Xi vary, neither the outputs of the NAND 6 and an INV 7 nor the output of the EXOR 5 varies. For the purpose, the multiplier-fixed multiplication is performed and when the enable signal C3 is 0, the electric power loss accompanying the operation of those elements is reduced. Consequently, the power consumption at the time of the multiplier-fixed multiplication is reduced.

Title: Semiconductor device and its mounting method
Inventor: TSUBAKI YUICHI
IPC: H05K7/14
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of possibilities for imperfect connections between the terminals of a substrate and a motherboard in the case of heat generation of a semiconductor module, by bending a flexible substrate mounting a semiconductor module so as to lift the semiconductor module, and connecting the substrate with the motherboard. SOLUTION: A substrate 2 which has a semiconductor module 1 mounted is further mounted on a flexible substrate 3 for connection. This substrate 3 is bent inside and connected with a motherboard 5, while lifting the semiconductor module 1. Thus, a space is formed between the substrate 2 and the motherboard 5. In other case, the flexible substrate 3 connected with the substrate 2 mounting the semiconductor module 1 is bent outside and connected with the mother board 5 while lifting the module 1. Thus, a space is formed between the substrate 2 and the motherboard 5. As a result, direct contact of the substrate 2 and the motherboard 5 is avoided, and heat generated from the semiconductor module is prevented from directly traveling to the motherboard.

Title: Method of resynchronizing node in computer network
Inventor: AREN EDOWAADO BARATSU
IPC: H04L29/06
Filed: 1988-06-10
Abstract: PURPOSE: To resynchronize nodes within a limited time, without the generation of ping-pong effect by activating a session from the other node, when a fault of a session is found out at some node, and exchanging characteristic messages between the adjacent nodes. CONSTITUTION: When one node receives the report of session stop, before both the sessions are up at the time of start or recovery, that node simply executes a retrial in the case of transmission session or waits for the retrial of his party in the case of reception session. When the logically up node receives the report of stop through one LU6.2 session, that node cancels the other session. A transmission module 36 starts exchanging this characteristic message, by sending a capability request through an output physical session. Thus, the ping-pong effect is avoided, and both nodes start a recovery sequences while being mutually tuned.

Abstract: PURPOSE:To detect the end of the life of a battery, by using as an active material for the positive electrode of the battery silver oxide particles, whose surfaces are coated with silver chloride, so as to permit the voltage of the battery to gradually decrease at the final stage of its discharge life. CONSTITUTION:As an active material for a positive electrode compound 3, is used argentous or argentic oxide particles whose surfaces are coated with silver chloride. This permits the voltage of a battery to gradually decrease at the final stage of the discharge life, thereby enabling the detection of the end of a battery life. To form a silver chloride film on each of the aforementioned silver oxide particles, it is preferred to form first argentous oxide through a reaction in an aqueous alkaline solution or argentic oxide through a reaction in an aqueous alkaline solution containing an oxidizing agent and then to form the silver chloride film on each argentous or argentic oxide particle in the same reaction solution. Alternatively, after preparing argentous or argentic oxide particles in the alkaline solution as described above, it may also be possible to filter the alkaline solution containing the reaction product, i.e., silver oxide particles, wash the particles with water, and then to form a silver chloride film on each silver oxide particle in water.

The method is started from these points, subsequently, the minimum difference among the nine pieces of positions disposed symmetrically around these starting points is tested with less prescribed number of samples or lines for a step.
