In a CMOS circuit including a source diffusion layer and a well region which are at the same potential, a P.sup.+ -type source diffusion layer and an N.sup.+ -type substrate diffusion layer are formed in a portion corresponding to a source region in a surface area of an N-type well region. A source contact is formed on the source and substrate diffusion layers through a salicide layer to connect the diffusion layers to their upper wiring layer. Since, therefore, the source contact can be arranged closer to a P-type well region, the layout area can be reduced.

A silicon nitride ceramic sliding material comprising silicon nitride crystal grains and a grain boundary phase and having a porosity of 2 to 10% and a maximum pore size of 20 to 100 .mu.m. The silicon nitride ceramic sliding material preferably has a textural structure wherein the proportion of the total area of silicon nitride crystal grains of 0.1 to 10 .mu.m.sup.2 in area to the total area of all the silicon nitride crystal grains present in an arbitrary two-dimensional cross section is 30 to 90% and the proportion of the number of silicon nitride crystal grains of 2 to 10 in aspect ratio to the number of all the silicon nitride crystal grains present in that cross section is at least 20%. The material is produced by mixing a silicon nitride powder with a sintering aid powder, molding the resulting mixture, then heat-treating the resulting molded body in a nitrogen-containing atmosphere under reduced pressure at 1,000 to 1,500.degree. C., and then sintering it in a nonoxidizing atmosphere under ordinary pressure or under pressure, at 1,550 to 1,800.degree. C.

A balancer is provided in the outer circumferential portion of a rotor of a spinning reel at the rear end of the rotor and located at the side of a bail in the fishline winding position thereof so that the center of gravity of the reel is located under a reel leg to facilitate the manipulation of the reel, and the rotative balance of the rotor is improved to stably and smoothly wind a fishline on the reel. The axis of the pivotally coupled portion of a bail support member, which is pivotally coupled to a bail support arm, is off set from the axis of the rotor toward the side of the bail in the fishline unwinding position to reduce the weight of the balancer.

A handle folding device for use in a fishing reel, capable of preventing a handle from being erroneously folded during the winding operation of the handle. A handle can be moved from the stand-up condition thereof to the folded condition thereof by operating a handle stopper. A handle stand includes a projecting portion having a tapered engaging portion and a preventive portion for preventing the movement of the handle stopper. The tapered engaging portion and preventive portion are contactable with the handle stopper. The preventive portion prevents the movement of the handle stopper during the winding operation of the handle.

In the preliminary authentication stage, the mobile station (35) is authenticated by sending from the home network (30) to the roamed network (31), a plurality of pairs of first random numbers (RNDa.sub.1, . . . , RNDa.sub.n) and calculation results (SRESa.sub.1, . . . , SRESa.sub.n) of the cipher function (f), which calculation is performed at the home network using the secret key (ki) and the first random numbers (RNDa.sub.1, . . . , RND.sub.an), by sending, from the roamed network to the mobile station, third random numbers formed by coupling second random numbers (RNDb.sub.1, . . . , RNDb.sub.m) produced at the roamed network with the first random numbers (RNDa.sub.1, . . . , RNDan), by sending, from the mobile station to the roamed network, calculation results (SRESa.sub.1, . . . , SRESa.sub.n, SRESb.sub.1, . . . , SRESb.sub.m)) of the cipher function (f), which calculation is performed at the mobile station using the secret key (ki) and the sent third random numbers, and by confirming, at the roamed network, coincidence of the calculation results (SRESa.sub.1, . . . , SRESa.sub.n) sent from the mobile station with the calculation results (SRESa.sub.1, . . . , SRESa.sub.n) sent from the home network. In the main authentication, the mobile station is authenticated by using a pair of the second random number (RNDb.sub.1, . . . , RNDb.sub.m) and of the calculation result (SRESb.sub.1, . . . , SRESb.sub.m) with respect to the second random number (RNDb.sub.1, . . . , RNDb.sub.m), sent from the mobile station.
摘要:
A multi-port-type semiconductor memory including an address comparator comprises a memory cell array which includes a plurality of memory cells arranged in rows and which includes two pairs of word lines for selecting the memory cells. The two word line pairs are driven each by one of two row decoders to which independent address signals are supplied. The address signals supplied to the two row decoders are input to the address comparator so as to detect coincidence between these signals. Further, a control circuit is provided in the semiconductor memory in order to inhibit the operation of one of the two row decoders when coincidence between the address signals is detected by the address comparator.
摘要:
A bail inverter for a spinning fishing reel in which an operating rod slidable in the longitudinal direction thereof is engaged in a slender opening of a bail support arm which is connected to a bail member, and the bail support member is urged by a spring so that the bail support member remains in a fishline winding position or a fishline unwinding position beyond dead center. The rear end of the operating rod can protrude from the bail support arm. One side portion of the operating rod and the bail support arm are provided with restrictors for restricting the quantity of the protrusion of the operating rod.

This invention relates to a method of producing a corrosion-, heat- and wear-resistant member which comprises packing an atomized powder of a high-carbon high-chromium steel into a capsule, heating the capsule packed with the powder, then extruding the capsule packed with the powder to obtain a stock not containing carbide grains greater than 3 .mu.m, working the stock, polishing a surface of the stock, and evaporating a film of TiC and/or TiN onto the polished surface, and further a corrosion-, heat- and wear-resistant member produced by the method. The corrosion-, heat- and wear-resistant member according to this invention is suitable for being members for tools used under extremely severe conditions, such as various tools for can manufacturing, molding tools for reinforced plastics, etc.
