Title: Cooling hole machining method for gas turbine blade
Inventor: SHIGE TAKASHI
IPC: B24C1/00
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To save labor as against a conventional way in which ceramic coating is applied after perforation is carried out and to prevent generation of a crack, which may be caused when perforation is carried out in a ceramic coating layer, a bond coating layer, and a blade base member at a stroke by means of laser beam machining, in the blade base member in the vicinity of a cooling hole.

Title: Traveling controller for beam light guidance type working car
Inventor: YOSHIKAWA KOJI
IPC: G05D1/02
Filed: 1992-11-06
Abstract: PURPOSE:To attain a steering by detecting a deviation value from a proper steering position at a next process start edge part after a steering operation based on the information of an optical sensor, and correcting the steering pattern so that the deviation value can be decreased based on the information at the previous steering position, thereby adding an appropriate correction to a steering pattern. CONSTITUTION:A steering control means 100 controls the steering so that a working car can automatically travel along a guidance beam light, based on the received information of a steering control optical sensor 17 which receives the beam light. Then, the steering control means 101 controls the steering so that the working car can rotate by a prescribed steering pattern toward the start edge part of the next traveling process adjacent to one traveling process as the working car reaches the end edge part of one traveling process. At this time, a steering operation deviation value detecting means 102 detects the deviation value from the proper steering position of the working car at the start edge part of the next traveling process after the steering operation, based on the information of the optical sensor 17, and corrects the steering pattern so that the deviation value can be decreased.

Title: Data reproducing device
Inventor: HORIGAMI KOICHI
IPC: G10L13/00
Filed: 1985-12-27
Abstract: PURPOSE:To accurately reproduce only desired information along with acoustic information and nonacoustic information at the same time by detecting control information recorded on a recording medium at constant intervals and separating acoustic information data and nonacoustic information data which are recorded by separating each (n)-bit sample in a sample array into (n-m) bits and (m) bits. CONSTITUTION:A time base correction processing part 18 outputs block information data to a sound/image separation processing part 19 with a clock of 2XfS=87kHz. Then, the sound/image separation processing part 19 sends out the high-order 13 bits of each 16-bit input data to a D/A 20 and the low-order 3 bits to an image processing part 21 separately. The D/A 20 converts the 13-bit digital data sequence into an analog signal, which is outputted as a sound by an acoustic information output part 22. Further, the image processing part 21 converts the 3-bit digital data sequence into an analog image signal, which is displayed on the picture of an image information display part 23. Thus, subcode information is used for retrieval together with control information in one block to obtain only desired information accurately along with acoustic information and image information.

Title: Fluorinated resin pipe for circulating cooling water conveyance
Inventor: TOMIMATSU KAZUNARI
IPC: F16L9/12
Filed: 1988-11-25
Abstract: PURPOSE:To prevent a microorganism from propagating and keep a flow rate of circulating cooling water constant at all times as well as to make the worsening of water quality in this cooling water avoidable by making an outer circumferential surface of a pipe body of a circulating cooling water conveying fluorinated resin pipe so as to be covered with a light impermeable cover body. CONSTITUTION:Since light struck on a pipe body 5 after being transmitted from a clearance between wires of a wire braid 3 from the outside is absorbed by a cover body 7, any light is no longer penetrated into a pipeline of the pipe body 5. Accordingly, when circulating cooling water flowing in the pipeline partially stagnates, forming a dead water region and stopping an electronic device, and a cycle of the circulating cooling water is stopped for hours, even if microorganisms such as bacteria, algae, etc., are contained in the circulating cooling water or make-up water for supplying this cooling water, propagation of these microorganisms is in no case promoted. Likewise, such mucilaginous slimy material is no longer generated in the circulating cooling water. Therefore any pressure loss in this cooling water due to sticking of this slime is never increased and, what is more, a flow rate of the circulating cooling water per unit time can be kept constant.

Title: Fuel cell
Inventor: MIZUNO SEIJI
IPC: H01M8/02
Filed: 1994-11-07
Abstract: PURPOSE: To achieve stabilization of large output by promoting drainage in a fuel cell. CONSTITUTION: An oxidized gas passing groove 18 formed on a collector 17 on a cathode 16 side is so formed that its depth may be gradually increased toward a gas discharging port 18b from a gas introducing port 18a. Accordingly, output can be prevented from being decreased caused by blockage of the gas passage caused by the accumulation of formed water since the formed water can be prevented from being accumulated in the oxidized gas passing groove 18 by discharging the formed water to be generated in the oxidized gas passing groove 18 by gravity. Since the contact area of the collector with the electrode is not reduced, the contact resistance between both sides can be reduced.

Title: Tire chain for dual tires
Inventor: CLARK LARRY C
IPC: B60C27/22
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To draw the central part of the crossing member into the space between the dual tire treads and reduce abrasion by providing a core surrounded by a spiral spring and using a central member having elasticity and dimensional stability. SOLUTION: A crossing member 16 is maintained in an appropriate tension state on both treads of the dual tire through cooperation of an elastic tensioner 48 and a central member 50. The central member 50 is floated to move circumferentially during driving of the vehicle, drawing the chain into the space between tires of the dual tire. The central member is moved at a lower ratio than rotation of the tire. This prevents the central member from continuously drawing to twist and bend a specific crossing member. Otherwise, a desired uniform zig-zag pattern of the crossing member 16 on the dual tire may be distorted. The floating central member 50 reduces damages of the crossing member 16 at a place where the crossing member 16 comes into contact with the central member 50. Accordingly, the entire tire chain moves circumferentially during driving of the vehicle, thus reducing abrasion.

Filed: 1991-10-17
Abstract: PURPOSE:To set a low energy consumption state without increasing external terminals at a microcomputer for card in an ISO standard and further to completely return from the low energy consumption state to an original state. CONSTITUTION:An interruption detecting circuit 5 is added to an I/O port 3 of the microcomputer having the low energy consumption state so as to detect the start bit of a transmitting data signal as an interrupted input. In the low energy consumption state, this interruption detecting circuit 5 is activated and the I/O port 3 is turned to an inactive state.

In the low energy consumption state, an I/O terminal is functioned as an interruption terminal, and the state is changed into the normal operation state only by applying the transmitting data signal and interrupting a CPU. In the normal operation state, the I/O terminal is functioned as the input/output terminal of the transmitting data signal.
