Filed: 1984-09-26
Abstract: PURPOSE:To reduce pattern dependence on the reading of a memory for forming a plurality of first aluminum reinforcing wires along the direction of a word line as the longitudinal direction of a memory cell plate. CONSTITUTION:A capacitance electrode 3 is shaped on the whole memory cell array on a field insulating film 18, and an aluminum reinforcing wire 5 is connected to the capacitance electrode 3 through contact holes formed at regular intervals at the end sections of a memory cell array. The reinforcing wire consists of the same aluminum layer as a word line WL, and extends in parallel with the word line WL. A reinforcing wire 6 is composed of the same aluminum layer as a data line DL, and extends in parallel with the data line DL.

IPC: G01S13/02
Filed: 1998-07-15
Abstract: PROBLEM TO BE SOLVED: To enable to detect up to the total of the maximum number of targets to collect by each radar device by controlling the detection bearing of each radar device and separating their covering areas. SOLUTION: Target information detected by a signal processing device is outputted to a device for detecting the number of targets to collect, and the number of targets being collected at present is detected from among the target information. Here, the number of targets to collect is compared with the maximum number of targets to collect among the information stored in a storage device. Then a radar device Ry adjacent to an radar device Rx with the maximum number of targets to collect or more is selected, a bearing 16 of limited monitoring is computed so that the cover areas 14 and 15 of the radar devices Rx and Ry are separated as much as possible. Then the radar device Rx is directed to monitor only the bearing 16 of limited monitoring, and only the radar device Ry is directed to detect a target 18 in a part 17 at which their cover areas are superposed.  By this, the saturation in the number of targets to collect by the radar device Rx is prevented. By this, a plurality of radar devices do not detect the same target.

Further, the margin of press-in of the valve seat 5 in the cylinder head 1 is increased, and the valve seat 5 is reliably held at the cylinder head 1.

Title: Manufacture of negative plate for sealed alkaline storage battery
Inventor: HENMI TOSHIO
IPC: H01M4/62
Filed: 1983-10-26
Abstract: PURPOSE:To increase the porosity, the gas-absorbing ability and the active material utilization rate of a negative electrode for a sealed alkaline storage battery by mixing cadmium oxide powder with thermoexpansive capsules containing a low boiling hydrocarbon. CONSTITUTION:After 100pts.wt. of cadmium chloride powder is thoroughly mixed with 5-10pts.wt. of thermoexpansive microcapsules consisting of vinylidene chloride copolymer shells containing a low boiling hydrocarbon such as butane, the mixture is kneaded with a viscous agent such as polyvinyl alcohol and water to make a negative paste. After the negative paste is packed into a core member, the thus obtained body is heated until the volume of the thermoexpansive microcapsules becomes about 50 times their original volume thereby completely diffusing the low boiling hydrocarbon outside the capsules. After that, heating is performed to decompose the shells of the capsules, thereby manufacturing a negative cadmium electrode having many fine holes in its active material. By the means mentioned above, it is possible to increase the porosity, the gas-absorbing ability and the active material utilization rate of the negative electrode.
