Title: Cable stiffened water pipe bridge
Inventor: NAGAHARA MITSUYOSHI
IPC: E01D11/02
Filed: 1994-03-18
Abstract: PURPOSE:To strengthen the stiffening action against load from all directions although a cable stiffened water pipe bridge is simple in construction. CONSTITUTION:Both end parts 11 of a water pipe bridge main body 1 are fitted to the fitting parts 4 on abutments 2, and a DELTA-shaped supporting material 3 is fixedly secured on the nearly center of the main body. Cables 5 inserting through two apexes 31 of the lower part of the supporting material 3 and obliquely connecting together the fitting parts on both ends are respectively tensly provided below both side of the main body 1. Because the DELTA--shaped supporting material 3 receives cable tension at one position on the center, effective stiffening action acts in the vertical direction. Simultaneously even against the horizontal direction in which the stiffening action can not be obtained by simple construction of customary technique, component of oblique tension acts and hence stiffening action acts. The maximum span of a pipe can be lengthened although it is one of simple construction, and hence the reducing effect of construction cost, material cost, construction period, and the like are remarkable.

Title: Formation of compound semiconductor layer
IPC: H01L21/203
Filed: 1992-03-31
Abstract: PURPOSE:To form a group III-V semiconductor epitaxial layer of high quality and good surface flatness on a single crystal of non-polar or different lattice constant. CONSTITUTION:An Al layer 2 of one atomic layer is formed on an Si substrate 1 at a low temperature of 400 deg.C or below and then P is supplied successively. The processes are repeated to form an Al P low temperature buffer layer 3. A GaP low temperature buffer layer 4, an AlAs low temperature buffer layer 5 and a GaAs low temperature buffer layer 6 are made to grow one by one thereon by a similar alternate supply method. A temperature is made to rise while supplying As and a Gaps buffer layer 8 is formed by an ordinary simultaneous supply method. Then, a temperature is lowered and an InAlAs low temperature buffer layer 9 and an InP low temperature buffer layer 10 are made to grow one by one by the alternate supply method. Thereafter, a temperature is made to rise while supplying P and an InP layer 11 is formed by the simultaneous supply method. Since two dimensional growth from an initial stage can be thereby acquired even on a single crystal of non-polar or different lattice constant, interface defective density can be reduced and dislocation due to thermal strain can be restrained from rising again.

Title: Output drive circuit
Inventor: SATOU KOUICHIROU
IPC: H03K19/0185
Filed: 1983-04-28
Abstract: PURPOSE:To obtain a drive circuit where the rate of area occupancy on a chip is decreased and a large current supplying ability is provided by providing a level shift circuit converting a potential difference into a larger potential difference to an input stage of an MOSFET for drive. CONSTITUTION:An output of a CMOS inverter comprising a P-MOSFET2 and an N-MOSFET3 is given to a gate of a P-MOSFET4 for drive via a level shift circuit 7. Further, a power supply -VF for shift and an operating power supply VDD are given to the level shift circuit 7. However, the drain current is increased as the gate voltage is increased under the condition that the drain voltage is constant in the drain current characterisitic of an MOSFET. Thus, a large current drive circuit is realized by increasing the gate voltage by means of the level shift circuit 7. Further, the size of the MOSFET4 for drive is made larger, but the drive circuit is realized with a minimum area because the level shift circuit 7 requires the voltage drive only.
