Memory cells each having a floating gate (4), control gate (6), and source and drain diffusion layers (7a, 7b) are formed on a silicon substrate (1). A silicon nitride film (10) by low-pressure CVD is maintained as side wall insulating films on side walls of the gates in each memory cell. A silicon nitride film (11) by plasma CVD is formed to cover a memory cell array, and silicon oxide films (12a, 12b) are made on the silicon nitride film (11) to form an inter-layer insulating film. A common source line (13) connected to the source diffusion layer 7a is formed to embed in the silicon oxide film (12a), and a bit line (14) connected to the drain diffusion layer (7b) is formed on the silicon oxide film (12b).

According to the module 10, the other end 22 of each of the plurality of porous cylindrical bodies 12 the one end 20 of each of which is closed is opened to the gas chamber 58 between the end cap 18 and the end cover 54, and the end cap 18 is provided with the through-hole 53 leading from the gas chamber 56 outward, and the gas chamber 58 leads outward by means of a path passing through the through-hole 53 and through the porous cylindrical body 12. The module 10 can have a gas-passing path from the peripheral wall 24 of the porous cylindrical-body 12 outward through the gas chamber 58 and through the through-hole 53. Since the airtight sealing structure of the whole of the reaction container 60 can be formed independently of the airtight connecting structure of the through-hole 53 and the gas lead-out opening 64, the permeability and the like of the module 10 that has various dimensions can be measured by means of a common reaction container 60 formed to have a predetermined size and structure by forming the through-hole 53 in a predetermined form corresponding to the connecting structure with the gas lead-out opening 64, regardless of the size of the whole of the module 10.

A heavy duty pneumatic radial tire comprises a radial carcass, a main cross belt and a tread portion, in which the main cross belt is formed by laminating at least three rubberized cord layers so that the cords in each layer are parallel to each other but the cords between the adjoining layers are crossed with each other and extend in opposite directions with respect to an equatorial line of the tire. In such a tire, a pair of cushion rubbers are arranged between the adjoining rubberized cord layers constituting the main cross belt at their both end portions by setting a position relation between mutual cushion rubbers at both belt ends to an optimum value to thereby prevent or control the occurrence of the belt end separation failure.

According to a method for screening a nonvolatile semiconductor memory device, data is written to all memory cells. The data is slightly erased such that the memory cells have a positive distribution of threshold voltages. The threshold voltages of the memory cells are measured, and the number of memory cells whose threshold voltages are lower than a reference threshold voltage, is counted. When the counted number is not larger than the number of spare cells provided in a redundant circuit, the memory cells whose threshold voltages are lower than the reference threshold voltage are replaced with the spare cells. When the counted number is larger than the number of spare cells, the nonvolatile semiconductor memory device is determined as a defective one.

摘要:
A combinatorial weighing system includes a combinatorial weighing apparatus, a packing machine and master/slave changeover switch. The combinatorial weighing apparatus has a plurality of weighing machines for sensing the weight of articles supplied thereto, and a calculation control unit for performing a combinatorial calculation, based on weight data from the weighing machines, to obtain an optimum combination, and for causing weighing machines corresponding to the optimum combination to discharge their articles. The articles are then packed by the packing machine. The master/slave changeover switch switches between a mode in which the packing machine is the master of the weighing and packing operation and a mode in which the weighing apparatus is the master of the weighing and packing operation. The arrangement results in a combinatorial weighing apparatus which has greatly simplified hardware and which can operate in association with either a master- or slave-type packing machine.
