IPC: G01N27/41
Filed: 1989-12-20
Abstract: PURPOSE:To avert the deformation and closing of a gas diffusion hole even in an atmosphere contg. corrosive gases or gaseous fluorocarbon, etc., and to allow the execution of the measurement of an oxygen concn. stably over a long period of time by providing corrosion resistant material layers which cover at least the wall surface of the gas diffusion hole of a housing. CONSTITUTION:An anode electrode 2 and a cathode electrode 3 are formed on both sides of a solid electrolyte base plate 1. The internal space enclosed by the surface of the base plate 1 on the electrode 3 side and the inside surface of a cap 5 is formed. This internal space is communicated with the outside by the gas diffusion hole 6 bored in the cap 5. The corrosion resistant material layers 7 consisting of platinum or gold are formed on the wall surface of the diffusion hole 6 and the region, near the diffusion hole 6, of the outside and inside surfaces of the cap 5. The generation of reaction products in and near the diffusion hole 6 is, therefore, averted even if this sensor is used in the atmosphere contg. the corrosive gases. The oxygen concn. is stably measured even in the atmosphere contg. the corrosive gases in this way without allowing the diffusion hole 6 to be closed or reduced in diameter by the reaction products.

Title: Power saving method in common wireless system
Inventor: PIITAA JIYON MEIBII
IPC: H04B1/16
Filed: 1989-12-20
Abstract: PURPOSE: To save power in a single substation or a small group of substations by allowing a master station to transmit indication of a time slot number available for a substation desiring transmission of optional access through the use of the ALOHA protocol. CONSTITUTION: In the community radio system consisting of a master station PS and a plurality of substations 20, 22, 24, 26, the station PS uses the ALOHA protocol to send indication for an available time slot number to a substation going to make an optional access. Thus, the substation desiring power saving can recognize a period while power is interrupted for a radio section but a control section is still energized. In the case that many substations are in existence and they are divided into small groups, each small group is divided at least two parts, and only one part is energized for any time in all periods assigned to the small group or the energized substations are individually power- saved. Thus, power is saved for a single substation or substations forming a small group.

Title: Reactor core of fast reactor
Inventor: NISHI YUJI
IPC: G21C5/00
Filed: 1991-12-16
Abstract: PURPOSE:To improve the safety and to obtain a larger output by forming the lid opening mechanism of a gas cavity container at the upper side of a void aggregate with a shape memory alloy. CONSTITUTION:When the flow of the cooling material of an atomic reactor is reduced abnormally, the flow of the cooling material 5 flowing in to the inside of a void aggregate 33 is also reduced. As a result, the temperature of the cooling material 5 heated by a heat generating substance 47 rises abnormally. The cooling material 5 heated abnormally heats an expansion metal fitting 38 which consists of a shape memory alloy abnormaly. The metal fitting 38 restores its memorized shape and is contracted. As a result, a lid 45 is pulled to the outer side of a gas cavity container 42 and opened. As a result, a sealed gas in the container 42 is released to the inside of a lower opening container 46 to depress the liquid level of the cooling material, and a void space is formed. Consequently, neutrons generated in a fuel aggregate 21 are leaked to the upper side of the reactor core through the void space formed in the cooling material passage 40 of the aggregate 33, and a negative reactivity is applied to the reactor core.

Title: Method of preparing load transfer procedure to stop distribution transformer bank and load transfer controller
Inventor: INOUE HIROSHI
IPC: H02J3/00
Filed: 1993-12-27
Abstract: PURPOSE:To facilitate the change-over and restoration of a distribution line with a small number of operation processes by a method wherein a load transfer procedure is produced in accordance with the appointment contents of the bus-bar route appointment or distribution line route appointment of the transfer destination of a transformer to be stopped. CONSTITUTION:A substation is managed by a control station and distribution lines are controlled by respective sales offices in charge. The control station produces a transformer operation stop plan and, before the stopping action, a bus-bar route transfer destination bank appointment and a distribution line route transfer length are predetermined and transmitted to the monitor/controller 21 of the sales office in charge. The monitor/controller receives those instructions and produces a change-over operation procedure and performs the change- over control for the load distribution in the accordance with the procedure. Bus-bar linking circuit breakers are closed in the case of the bus-bar route transfer, however, and that operation is usually the job of the control station. Therefore, the sales office does not perform the closing control of the bus-bar linking circuit breakers for the bus-bar route transfer but performs the load transfer control for the distribution line route transfer. As a result, the number of change-over processes can be reduced.
