IPC: E02D5/48
Filed: 1995-02-02
Abstract: PURPOSE: To increase bearing power by pressing in an agglomerative fluid material in a cylindrical bag body whose upper and lower parts are installed on a ready-made pile by a band, and forming an expanded part on the pile lower end in a burying construction method. CONSTITUTION: By a band 5, a cushion material 7 and a cylindrical bag body 4 are fastened to the outer periphery of a steel pipe concrete composite ready- made pile 3 composed of a steel pipe 1 on the outer periphery and hollow concrete 2 brought into close contact with the steel pipe 1 on an inside surface, and upper and lower parts are installed. In the steel pipe 1 of the ready-made pile 3, a spiral flat projection 6 is arranged over the whole surface. An injection pipe 9 to inject an agglomerative fluid material into the bag body 4 is arranged in a hollow concrete part. Dislocation between the steel pipe 1 and the bag body 4 is prevented only by fastening them with low tensile force by the band 5, and the bag body 4 is reliably fixed to the ready-made pile 3.  Since the agglomerative fluid material such as cement milk is pressed in and hardened, the ready-made pile 3 and a hardening body 8 are firmly and integrally stuck together, and high bearing power is obtained.

IPC: H01L29/49
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To suppress degradation of transistor characteristics due to hot carriers by linking an N or P channel region with two materials having different work function in the vicinity of drain to form first and second gate electrodes and locating the forward end of a lightly doped diffused drain layer at a part of the second gate electrode.

The region D of the second gate electrode 7 is formed slightly larger than the overlapped region of the drain junction and the gate electrode 6. Preferably, the difference of work function between the gate electrodes 6, 7 is on the order of IV or above. This arrangement realizes an MOSFET structure where the inverted threshold voltage in the vicinity of drain is shifted, by an amount corresponding to the difference of work function, in the negative or positive direction as compared with that of the N channel region. More specifically, the forward end of a lightly doped diffused drain layer 4 is located at a part of the second gate electrode 7.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of executing the reserved job of a different original size. SOLUTION: When the original of a first feeding port is ejected into a second ejecting port, the reserved job is started and the original exists in a second feeding port (STEP S31/YES), the size of the original of the second feeding port is detected (S32). Further, the size of a settable original in the first feeding port is detected (S33) and when the size of the second original is the same as that of the first original (S34/NO), the reserved job is executed (S38). Further, when the size of the second original is different from that of the first original (S34/YES), post-processing is executed by a sorter (S35). Thus, it is unnecessary that the original of the reserved job is ejected into a first ejecting port. Therefore, the original is fed from the second feeding port and the copies of a registered number are made and ejected into different sorter bins respectively.  After that, the original is ejected into the second ejecting port (S36).
