IPC: H01S5/183
Filed: 1988-04-15
Abstract: PURPOSE:To have an optimum structure in an optoelectronic integrated circuit after completing a crystal growth at a time and obtain a high reflection factor by low contact resistance, by forming a lower reflecting mirror consisting of a semiconductor multilayer film on an n-type semiconductor substrate and forming an upper reflecting mirror by specific materials, thereby making a double heterostructure part columnar. CONSTITUTION:A multilayer reflecting film 4 is constructed by making semiconductor thin films 4A and 4B grow alternately to form a plurality of grouped multilayers. An upper reflecting mirror 8 acting as a p-side ohmic electrode concurrently is formed by depositing Ti, Pt and Au one after another. Positive holes injected from an upper electrode 10 or 8 are introduced into an active layer 6 through a clad layer 7 and electrons injected from a lower electrode 1 are introduced into the active layer 6 through an n-type semiconductor substrate 2, a buffer layer 3, the multilayer reflecting film 4, and a clad layer 5 and they recombine with each other to emit light. Its light is reflected between upper and lower reflecting mirrors 8 and 4 and is amplifired and then, a laser beam is emitted upwards. In such a case, each part of clad layers 7 and 5 and the active layer 6 is formed into the columnar shape which has nearly the same size as the diameter of the circular electrode 8. As there is an insulating layer 9 around them, an electric current flows only in columnar parts.

Filed: 1993-03-26
Abstract: PURPOSE:To simplify a device, and to contribute to safe operation by using a pair of gyros only corresponding to the progressive direction and an accelerometer and obtaining true acceleration, in which the effect of gravity by a gradient, etc., only in the progressive direction is eliminated, by arithmetic operation. CONSTITUTION:When a train 5 is accelerated at acceleration alpha on an up-grade at an angle theta, a gyro 3 detects an angular velocity. A moving-body acceleration detector 1 loaded on the train 5 successively integrates an output from the gyro 3 while using a line grade theta at the time of stoppage at a known station as an initial value, and computes the grade under the state of a figure. The indicated value alpha of an accelerometer 2 displays the sum of the acceleration alphaof the train and the component of force alphag lowering on the grade of the acceleration g of gravity, thus indicating the acceleration alpha of the train 5 by alpha=alpha'-gsintheta, then arithmetically operating the acceleration alpha by the moving-body acceleration detector 1. Accordingly, true acceleration is obtained by a simple device, and safety operation by an overcrowded railway schedule is conducted.

Title: Nonaqueous electrolyte secondary battery
Inventor: IKUYAMA SEIICHI
IPC: H01M10/0566
Filed: 1994-04-28
Abstract: PURPOSE:To enhance a cycle characteristic by using a polymer, which is composed chiefly of vinylidene fluoride thermally crosslinked by a polymer containing an amine group, as a binder which is contained in an anode mix and/or cathode mix. CONSTITUTION:An anode comprises an anode active material held within an anode collector by a binder, and a cathode comprises a cathode active material held within a cathode collector by the binder. A polymer composed mainly of vinylidene fluoride is used as the binder, and a polymer containing an amine group is used as a thermal crosslinking agent for the binder. A three- dimensionally networked structure is thus formed, and the forces of holding the active materials are enhanced by the crosslinked structures while the excellent characteristics of the polyvinylidene fluoride as the electrode binder are maintained. In the anode and cathode that use such a binder, the active materials are so strongly held on the collector surfaces that they hardly peel off during repeated charging and discharging, resulting in an enhanced charge and discharge cycle characteristic.

Abstract: PURPOSE:To improve the performance of following up variations in the load by driving a compressor by means of a gas engine, in which a part of an excess reformed gas is used as a fuel, and storing in a high-pressure case the compressed excess reformed gas which is then supplied to a fuel cell as occasion demands. CONSTITUTION:An original materil, after being converted into a reformed gas by means of a reactor 2 and a fuel reformer 1 having a burner 3, is supplied to a fuel cell 4. An excess reformed gas sent from the cell 4, after being reduced in its pressure by means of a pressure-controlling valve 21, is supplied to the burner 3 and supplied to a gas engine 11 through a flow-rate-controlling valve 25 to drive the engine 11. As a result, a compressor 13 is caused to operate to produce compressed gas which is then stored in a high-pressure case 15. The gas contained in the case 15 can be supplied to the fuel cell 4 through a pressure- reducing valve 16. As a result, gas can be supplied from the case 15 when the amount of the reformed gas supplied to the cell 4 becomes sufficient, thereby enabling the performance of following up the load to be improved.

IPC: G01N9/24
Filed: 1989-04-14
Abstract: PURPOSE:To use axially symmetrical heaters having no observation windows to measure the volume of a fused body by providing a high temperature furnace which surrounds and heats a vessel and providing an X-ray generator and a transmitted X-ray observation screen arranged on the side wall of the high temperature furnace with this furnace between them. CONSTITUTION:Since the X-ray generator and the transmitted X-ray observation screen are provided on the side wall of the high temperature furnace and the volume of the fused body in the vessel having a known volume is measured by transmitted X rays, an observation window required at the time of using visible rays is unnecessary. Therefore, heaters can be arranged axially symmetrically and the density of the fused body is accurately measured. Consequently, the change of density of the high-temperature fused body can be measured with less variance. This instrument can be applied to not only a semiconductor like Si, Ge, InP, or GaAs but an oxide.

Title: Optical parallel transmission system
Inventor: OMAE KENICHI
IPC: H04B10/03
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To effectively satisfy the safe standard of laser beams by transmitting the parallel data in parallel after encoding them into the data having approximately the same rate between '0' and '1' and then converting these data into electric signals. SOLUTION: An encoding circuit 1 encodes an input electric signal of 8 bits, for example, into an electric signal of 10 bits having the same number between '0' and '1'. The electric signals which are encoded by the circuit 1 are inputted to an electricity/light conversion circuit 2 and turned into 10 pieces of optical signals. Then these optical signals are inputted to a light/ electricity conversion circuit 3 of the receiver side via a tape fiber 6 consisting of a set of 10 pieces of optical fiber cables 5. The circuit 3 converts the received optical signals into the electric signals of 10 bits and then decodes them into the original signals of 8 bits in a procedure adverse to the encoding procedure of the circuit 2 via a decoding circuit 4 that is connected to the circuit 3.  In such a transmitting way of optical signals, the laser beams radiated from the fiber 6 are limited to 5 pieces at most and less than conventional 8 pieces even if the fiber 6 is cut by mistake.
