Title: Gallium phosphide arsenide epitaxial wafer
Inventor: SATO TADASHIGE
IPC: H01L33/00
Filed: 1992-07-28
Abstract: PURPOSE:To obtain an extremely small decrease in luminance of a light emitting diode during service and reduce a forward rise voltage, by using a wafer with a specific carrier concentration of a gallium phosphide arsenide mixed crystal rate constant layer into which a nitrogen is doped. CONSTITUTION:A gallium phosphide epitaxial layer 2, a gallium phosphide arsenide mixed crystal rate chafe layer 3, a gallium phosphide arsenide mixed crystal rate constant layer 4 and a gallium phosphide arsenide mixed crystal rate constant layer 5 into which a nitrogen is doped are formed on a single crystal substrate 1. When the layer 5 is grown, after the layer 2 to the layer 4 whose carrier concentration is in the range of 5X10<16>cm<-3> to 5m10<17>cm<-3> are grown, only a supply of a dopant is stopped and then the layer 5 is grown by introducing an ammonia, and thereby the Rallium phosphide arsenide mixed crystal rate constant layer 5 into which an element with a carrier concentration of less than 3X10<15>cm<-3> is doped can be obtained. Thus, a light emitting efficiency can be improved and a life of a light emitting diode can be prolonged.

Title: Sand cover mechanism of seabed boring device
Inventor: OTA KAZUYUKI
IPC: E21B21/00
Filed: 1992-07-28
Abstract: PURPOSE:To prevent sand from flowing into a bored hole, enhance the ability of a device to bore holes and reduce costs by providing at the lower end of a guide pipe a slide cover for covering the mouth of a bored hole when lowered, the guide pipe guiding a drilling rod down to the seabed. CONSTITUTION:To perform the construction work of crushing the rock 3R of the seabed 3, a ship 2 on the sea is towed to a work site and a support 21 is put down to the seabed 3 to position the ship 2, and a mast 4 is suspended to extend the rod 7 of a rock drilling machine 6 and boring is started by a bit 9. While the bit 9 is pressed against the rock 33R by application of thrust to the rod 7, boring is performed simultaneous with striking and rotation of the bit and sludge then formed is discharged upwards through a guide pipe 10, together with a flushing fluid F. As sand 13 or the like located near the mouth of the hole bored is discharged, a slide cover 11 seated thereon is gradually lowered and is seated on the rock 3R and prevents sand 13 from flowing in from all directions due to a tide T. The ability of the device to bore holes is thus enhanced while the time required for the work can be shortened.

IPC: G01N27/62
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To provide a retrieval method, a retrieval device, and a recording medium for retrieval by which an unknown polymer sample can be easily identified. SOLUTION: An unknown polymer sample is pyrolyzed by a pyrolyzing means 2, and then, the pyrolyzed products are separated with a separation column 4. Each the separated pyrolyzed product is ionized by a mass spectrometer 5 every prescribed time so that molecular ions and fragment ions are generated, while detection data are created by detecting strengths of the generated molecular ions and the fragment ions. The detection data are added up every set of the detection data by a personal computer 6 so that total ion strengths are obtained. A chromatogram is created on the basis of the total ion strengths. The detection data, which are included in the total ion strength corresponding to each peak of the chromatogram, are added up every ion having an equal mass so that an added-up mass spectrum of the unknown polymer sample is obtained.  Added-up mass spectra of plural known polymer samples are obtained by the same method as the unknown polymer so that a database is created on the basis of them. The added-up mass spectrum of the known polymer sample, which has a high rate of accordance with the added-up spectrum of the unknown polymer sample, is retrieved out from this database.

Title: Sealed lead-acid battery
Inventor: SUZUI YASUHIKO
IPC: H01M10/52
Filed: 1992-07-30
Abstract: PURPOSE:To prevent decrease in electrolyte so as to enhance the life characteristic of a sealed lead-acid battery by making the number of negative plates greater than that of positive plates by two or more, and disposing positive plates adjacent each other at other than both ends of the group of pole plates, and disposing an acid resistant, nonconductive thin plate between the adjacent negative plates. CONSTITUTION:In a group 4 of pole plates, eight negative plates 2 are used for six positive plates 1. Negative plates 2 are located at both the right and left ends of the group 4 of pole plates and two negative plates 2 are also located adjacent each other at the center of the group and an acid-resistant, oxidization-resistant thin plate made from nonconductive polypropylene or the like is disposed between the adjacent negative plates. A separator 3 is sandwiched between the plates 1, 2 and they are stored in a battery jar and a predetermined amount of sulfuric acid electrolyte is poured into the jar and an opening is covered with a lid to provide a pealed lead-acid battery. The thin plate 6 divides the group of pole plates into two blocks and causes oxygen gas generated from the pole plate 1 to be readily introduced up to the center pole plate 2, which then absorbs the gas; therefore, dissipation of the oxygen gas is prevented even during continuous charging and the life characteristic of the battery can be enhanced.
