Title: System for detecting mobile body position
Inventor: HATTA TATSU
IPC: G01S1/00
Filed: 1987-02-13
Abstract: PURPOSE:To measure the position of a mobile body at a relatively long period by receiving a high frequency magnetic field produced by a cross induction couple and finding the phase difference between the in-phase (out-of-phase) voltages of the couple. CONSTITUTION:Two cross induction bodies 1 and 2 which are relatively close in conductor pitch are arranged on the ground and a high frequency magnetic field produced by those conductors is received by plural antennas 3a-3c fixed on the mobile body. Induced voltages received by the antennas 3a-3c are inputted to a signal processing circuit 8, which finds the in-phase (out-of-phase) voltage of the induced voltages based upon the magnetic fields of the conductors 1 and 2. Then the position of the mobile body is detected synchronously and continuously from the phase difference. In this case, the detection period becomes equal to beats of the pitches of both conductors 1 and 2, so the relatively long position detection period is realized by the conductor couple with the relatively short pitches.

Title: Light source with variable colored light
Inventor: TOHO MAKOTO
IPC: H01J63/06
Filed: 1988-02-15
Abstract: PURPOSE:To vary the color temp. with a single light source by allowing a fluorescent substance affixed to the inner surface of a light permeative shell to emit visual light by means of electronic excitation, and by furnishing a control means to emit visual light by heat emission from an incandescent filament cathode. CONSTITUTION:An anode consists of a transparent conductive film 6 affixed to the inner surface of a glass tube 5. Fluorescent substance 7 is applied to the inner surface of this film 6. A comparatively high DC voltage V1 is impressed between a lead 1 internally connected with this film 6 and another lead 2 connected with one end of an incandescent filament cathode 4 in such an arrangement that the lead 1 will become positive electrode, while a voltage V2 is impressed between the lead 2 and a third lead 3 in connection with the other end of the cathode 4. Accordingly hot electrons are emitted from the filament 4 and accelerated, and the fluorescent substance 7 is energized to emit light. The cathode 4, on the other hand, emits incandescent light, and consequently the light emitted to outside the glass tube 5 assumes white as the two are mixed. Therein change of the voltages V1, V2 enables emission of any desired color.

IPC: G02B7/02
Filed: 1990-02-15
Abstract: PURPOSE:To prevent the failure of a press-fitting material by interposing a deformable elastic sleeve provided with an external pressure relief part and an internal pressure relief part between the columnar press-fitting material which is a brittle material and a material to be press fitted. CONSTITUTION:The elastic sleeve 11 is press-fitted into the center of the opposite end faces of a cylindrical holding member 10 made of the brittle material.

Title: Data output circuit and d/a conversion circuit
Inventor: SASAKI HAJIME
IPC: H03M9/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To reduce the numbers of input-output pins and signal lines. SOLUTION: One of six parallel-serial conversion circuits 51 synchronizes a parallel composite signal CMP-P with 8-bit width inputted in 13.5 MHz frequency with a bit clock B-CLK outputted by a data clock output circuit 52 and converts it into a serial composite CMP-S. The frequency of the clock B-CLK is multiplied to eight times as high as 13.5 MHz. A DA conversion circuit 70a converts the signal CMP-S into an analog signal at every 8-bit word. The circuit 70a accurately recognizes the value of every word from continuous signals CMP-S without a pause on the basis of 13.5 MHz data clock D-CLK supplied by a data clock output circuit 53.

Title: Method and apparatus for detecting disconnection of mesh belt
Inventor: FUKUDA KOICHI
IPC: G01B11/02
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To judge the disconnection of a mesh belt accurately. SOLUTION: The whole width of a mesh belt 3 is divided into four photographing divisions 9vf, 10vf, 11vf, 12vf to photograph by separate cameras per photographing division. A ratio of area of metallic wire constituting the mesh belt 3 to area of a clearance part of the mesh belt 3 is obtained per photographing division. Furthermore, the average of the above-mentioned ratios is obtained in adjacent two photographing divisions 9vf and 10vf, 10vf and 11vf, and 11vf and 12vf. This average value is compared with a threshold value for judging disconnection. Consequently, disconnection can be accurately judged even when a disconnection part 300 having a length that is judged to be a part where disconnection occurs is provided across two photographing divisions 9vf and 10vf.

Title: Press type resistance welding method for work consisting of aluminum material and device and electrode for said method
Inventor: BUERUNAA UURETSUHI
IPC: B23K11/30
Filed: 1983-03-02
Abstract: Spot- and projection-welding of aluminum sheets has always been connected with difficulties mainly because of the surface layers of aluminum oxide, and even by pickling, these difficulties could be only partly eliminated. The main difficulties have always been insufficient electrode life times, the unsatisfactory quality of the weld and especially the unsolved problem of achieving good quality welding and long electrode-life when using un-pretreated aluminum sheets. The problem has been solved in principle by using electrodes having profiled contact-surfaces, by means of which the layer of oxide is broken during pre-pressing and a direct contact between the electrode and unoxidized material of the workpiece is provided, the contact-resistance of which is lower than the portion of the overall resistance of the point of weld formed by the metal of the aluminum sheets to be welded together. In an appropriate welding machine, the means for switching-on the welding current are controlled in such a manner that the welding current is switched on only after a sufficiently large contact area and therewith a sufficiently low contact-resistance of this contact has been reached.

Title: Manufacture of high pressure fuel injection pipe material for automobile
Inventor: ASADA KIKUO
IPC: F02M55/00
Filed: 1995-01-30
Abstract: PURPOSE: To provide manufacture of a high pressure fuel injection pipe material for an automobile wherein the inner peripheral surface of a pipe is completely cleaned during manufacture and a fuel injection pipe is kept in a manufacturing state, and a hair crack during use is prevented from growth. CONSTITUTION: A thick fine metallic pipe material 1 having a fine hole with a hole diameter of 1.2-4mm through which fuel for injection flows and which is formed in a longitudinal direction is heated to 100-500 deg.C. After heating, dry ice fine grains 6 are blown against the inner peripheral surface of a fine hole 5 through a nozzle 3 connected to a dry ice blasting apparatus 2. A foreign matter peeled from the inner peripheral wall of the fine hole 5 is discharged to the outside of the thick fine metallic pipe material 1 by means of a gasified high speed dry ice flow. Simultaneously, the inner peripheral wall of the fine hole 5 is rapidly cooled for contraction and since a compression stress remains on the inner peripheral wall, the hair crack occurring to the inner peripheral wall of the fine hole 5 during forming processing is adhered through press from a periphery.  When a fuel injection pipe is manufactured and used, the hair crack does not grow owing to the rapid fluctuation of a pipe internal pressure and vibration of an engine and an operation life for stable injection operation is increased.
