Title: Installation device for three-way frame for elevator on wall surface of building
Inventor: NAITO HIROYUKI
IPC: B66B13/30
Filed: 1991-05-23
Abstract: PURPOSE:To facilitate installation works safely by fastening a partitioning plate in a L-shape in cross section covering the whole surface of a gap between the wall of a building and a three-way frame onto both the wall of the building and the support fixture of the three-way frame via plural holding fixtures furnished with flat sections with bolts and nuts. CONSTITUTION:The whole surface of a gap between the wall 2 of a building and a three-way frame 3 is covered by a partitioning plate 20 made of a steel plate in a L-shape in cross section the surface of which lath metal is bonded on, and the partitioning plate 20 is fastened to an anchor bolt 22 fixed onto the wall 2 of the building and to a support fixture 4 fixed on the three-way frame 3 with plural holding fixtures 21. Both a hole bored in the support fixture 4 and a bolt hole bored in each holding fixture 21 are made oblong, and each holding fixture 21 is formed with flat sections. In this case, installation can be done only by fastening using bolts and nuts but not by welding. As a result, works can be done easily and safely even in a narrow space. In addition, since each holding fixture 21 is formed with the flat sections, when mortar 11 is filled in a gap, time required for filling mortar can be shortened because mortar 11 becomes used to each holding fixture 21.

Title: Method for bonding fiber reinforced resin structure
Inventor: NIIMI TAKAYASU
IPC: B29C70/16
Filed: 1985-05-31
Abstract: PURPOSE:To obtain predetermined strength by eliminating the cutting of a fiber, by winding a continuous fiber bundle impregnated with a resin in an amount of 70$85% based on a predetermined winding amount around a cylindrical insert jig under low tension and subsequently winding the remaining fiber bundle therearound under high tension while the previously wound fiber bundle is pressed. CONSTITUTION:At first, a fiber bundle 1 is wound around the groove 2a of a jig 2 to mold a ring part 5 and subsequently wound around an insert metal jig 4 to mold a spork part 6. Tension is applied at the winding time of the ring part 5 but, when the fiber bundle 1 is transferred from the ring part 5 to the spork part 6 or, contrarily, when from the spork part 6 to the ring part 5, each fiber is bent at an angle of almost 90 deg.C and, therefore, high tension can not applied to the fiber bundle 1 wound around the bent part. That is, the fiber bundle 1, to which low tension was applied, is wound around the insert metal jig 4 by the prescribed number of times to form the spork part 6 and the fiber bundle 1', to which high tension was applied, is wound around the fiber bundle 1 between flanges 7 of the metal jig 4 while the base part of the spork part 6 is pressed. When the fiber bundle 1' is wound 5-20 times by this method, the spoke base part 8 is compressed to generate bonding strength between the base part 8 and the insert metal jig 4.

A gate electrode 14 is build on the GaAs layer 131, and ions are implanted using the gate electrode 14 as a mask to form a source and a drain region, 15 and 16. Carriers supplied from the atom doped layer 132 of high impurity concentration to the semiconductor layer 131 are able to travel in mobility as the semiconductor layer 131 is small in concentration of impurity, so that the semiconductor layer 131 is used as a channel region. By this setup, a field effect transistor of this design can be improved in mutual conductance.

Title: Isolated type digital subscriber radio system
Inventor: HAMADA TATSUYOSHI
IPC: H04L7/02
Filed: 1987-05-18
Abstract: PURPOSE:To attain the system constitution of economical digital transmission even at a remote location where a DCS clock distributor is not arranged by confirming the frequency division phase of a 1/M frequency division means by a signal generated from a synchronizing signal generating means. CONSTITUTION:Switching discrimination signals 205-1-205-N generated by a network signal interruption, out of frame synchronism, manual switch or power application prepared corresponding to network side signals 2-1, 2-1-2-N are inputted to a switching discrimination section 24. A synchronizing signal generating section 22 receiving a network frequency division signal 206 from a switching section 23 gives a reference signal 207 synchronously with a network side frequency-division signal 206 to a signal processing section 25, and the signal processing section 25 applies signal processing the base station side synchronously with the network. On the other hand, the output phases of frequency division sections 21-1, 21-2-21-N are confirmed by the timing signal 201 of the synchronizing signal generating section 22. Thus, the phase jump of the frequency-division signal 206 attended with the changeover of output signals 203-1, 203-2-203-N of each frequency division section by the changeover section 23 is minimized.

CONSTITUTION:GaP polycrystal and N type impurities are mixed in a Ga melt, and the melt is kept at a temperature of 1,030 deg.C. The surface of a substrate is wetted at a time A. A minute amount of Si is added to the melt. At a time B, H2S with high concentration is flowed for a short time. The temperature is decreased at a low speed. Growing 12 of an N layer is performed at a concentration 2 that is higher than the concentration 1 of the substrate. Then N layer growing 14 is performed with the rest period of 45-120min being provided during the growth. Since the rest period (with constant temperature being kept) is provided, the N layer, whose impurity concentration is gradually lowered in correspondence with the decrease in dislocation density, is obtained. Finally, in the N type growth layer 14, Si3N4 is deposited by NH3 and Si in the melt. The Si in the melt is decreased to 1/4-1/10. An N layer, wherein the concentration 4 of the N2 is about 10<16>cm<-3>, which is very low, is formed. At a time D, Zn is introduced, and a P layer growth at a high concentration 5 is performed. In this constitution, an LED, which has high emitting efficiency and a long life, is obtained.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: OTSUKA IKU
IPC: F02D41/14
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To reconcile improvement of drivability and reduction of emission in an internal combustion engine controlling O2 storage amount in catalyst to fixed amount by a feedback control using an air-fuel ratio sensor. SOLUTION: When gain to be used in an air-fuel ratio(A/F) feedback control routine is set to a large value, A/F hunting is generated after a transient state and drivability is deteriorated (curve C1). When gain is set to a small value, an A/F fluctuation width is reduced and as a result, emission is increased (curve C2). In this case, when an engine operation state is in the transient state, gain is set to the large value, a feedback correction is performed for A/F, gain is set to the small value for deviation of A/F generated as a result and the feedback control is performed for A/F.
