Title: Compressor casing liner
Inventor: SUZUKI TADASHI
IPC: F04D29/54
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To easily exchange only a liner requiring its exchange in a compressor by substantially equally dividing a liner provided on a casing between it and rotor blades in the circumferential direction of the casing so as to have their plane shapes capable of respectively passing through the spaces defined between the tips of their adjacent rotor blades. SOLUTION: A casing 3 is arranged as to enclose rotor blades 2 mounted on a rotor 1 of a compressor, and an air inlet port 5 is connected to the tip of the casing. A casing groove 7 is formed in the casing 3 at a position opposed to the rotor blades 2, and liners 4 are fitted into the casing groove 7. Each of the liners 4 has a shape of a parallelogram parallel to the chord line (c) of the rotor blades 2, capable of pausing through the space defined between the tips of adjacent rotor blades 2, and substantially equally divided in the circumferential direction of the casing 3. When a damaged liner 4 is to be exchanged, after the rotor blades 2 are rotated a screw 9 for the liner 4 to be exchanged is unscrewed and then the liner 4 is drawn out toward the air inlet port 5.

Title: Shutter system for electronic camera
Inventor: AKAGI TOSHIAKI
IPC: H04N5/378
Filed: 1992-05-29
Abstract: PURPOSE:To obtain the shutter system of an electronic camera by which a time required until an appropriate exposure value is obtained can be shortened compared with a conventional circuit which operates an exposure control by an electronic shutter variation. CONSTITUTION:An objective image is image-formed on a CCD 2, and exposure information is outputted from a correlation double sampling part 3. The exposure information is integrated by an integration circuit 4, and converted into a digital signal by an A/D converter 5. A table 8 of a shutter speed which is preliminarily divided into blocks by steps being a permitted exposure range is stored in a storage part 9. A level comparing and judging part 10 judges which area includes the output of the A/D converter 5 by a threshold value indicating the boundary of a level area which is increased and decreased by step units and block units being the permitted exposure range. A shutter speed deciding part 11 decides the shutter speed by increasing and decreasing it by the step units and the block units according to the judged area and the present set shutter speed by referring to the table 8. A timing generator 7 supplies a pulse by which the decided shutter speed can be attained to a CCD 2.

Title: Fuel cell
Inventor: SAITO HAJIME
IPC: H01M8/02
Filed: 1993-07-05
Abstract: PURPOSE:To average the amounts of electrolyte consumed so as to provide an extended life by providing an electrolyte plate with a number of slits oriented from the supply side to the outlet side of fuel and air, and moving electrolyte on the low-temperature side to an output on the high-temperature side. CONSTITUTION:An electrolyte plate 3 is located between both electrodes 1, 2 and provided with vertical 4 and horizontal 5 slits. Because of the numerous slits 4, 5, the electrolyte plate 3 forms a gas flow from low- to high-temperature sides with increases in the concentrations of electrolyte in the slits 4, 5, thus moving the electrolyte to the high-temperature side. Therefore, fuel with which the electrolyte is consumed at relatively low speed on the inner surface of the cell and the electrolyte on the air-supply side can both be positively moved to the high-temperature side at an outlet, so the amounts of electrolyte consumed are averaged and cell life can be extended.

Title: Access control system
Inventor: KAMIJO YOSHIO
Filed: 1987-07-03
Abstract: PURPOSE:To facilitate the confirmation of a terminal and to prevent information from being stolen or forged by collating the outgoing number of a terminal from an ISDN switching network with the contents of a storage device and perform accepting operation corresponding to the right access. CONSTITUTION:When a terminal 4 which is allowed to read information out of a data processor 1 is connected to the processor 1 through the ISDN switching network 6, the network 6 sends incoming call information and the outgoing number of the terminal to the processor 1 over a D channel. The processor 1 receives them by its D channel processing part 10, sets the outgoing number in a register 12, and actuates a matching circuit 14. The circuit 14 matches the outgoing numbers in the register 12 and a storage circuit 13 with each other, and sets the right to access in a register 15 and informs a CPU 3 of that when they match with each other. The CPU 3 reads the contents of the register 15 and sends information to the terminal 4. In this case, a request to write from the terminal 4 is rejected. Similarly, a terminal 5 which is permitted to read and write information is allowed to make both requests. Then confirmation is performed with the outgoing number from the network 6, so information is prevented from being stolen by an illegal terminal.

IPC: G09B29/10
Filed: 1994-07-18
Abstract: PURPOSE:To speedily provide the route required by a driver from the start point to the destination in the device for searching route used for the navigation system. CONSTITUTION:A processor 15 decides the present position based on the information from a GPS receiver 11, direction sensor 12, distance sensor 13. It is overlapped on the map data in a map data base and displayed on a display device 17. When a driver sets the destination from a controller 14, the processor 15 searches the route with the minimum passage cost and displays it on the display device 17. When the driver does not want the recommended route, the processor 15 increases the passage cost of the link comprising the route and re-searches it. When the past route is overlapped in re-searching, it is not adopted. Thus, the route obtained by re-searching can be another one from the past results.
