Title: Spark plug installing method
Inventor: KAGAWA JUNICHI
IPC: H01T21/06
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To enhance the igniting performance of a spark plug, resistance against contamination and breakage, and the yield from the production line by confirming each spark gap formation, etc., simply and accurately in the process of installing an insulator in a metal body. SOLUTION: When an insulator 2 retaining a center electrode 3 is to be installed in a metal body 5 to constitute a single piece structure with an outside electrode 6, each spark gap 7 bounded by the outside electrode 6 and the foremost periphery of the center electrode 3 or insulator 2 is along with its dimension confirmed by an image processing device which incorporates a camera 10, and if the spark gap 7 is positioned outside the set range, the distance of each spark gap 7 is adjusted into the specified dimension by rotating or changing the insulator 2 appropriately, and thereby the correcting work for the spark gap thereafter is lessened and their heights are made even, which should lead to enhancement of the igniting performance and the resistance against contamination and breakage, and an optimum combination of insulator 2 and metal body 5 is obtained,  so that it is possible to heighten the yield from the production line.

Title: Steel floor slab bridge
Inventor: WAKINAGA TADASHI
IPC: E01D101/00
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To dispense with reinforcing material to reduce the manhour for welding by providing a steel bottom plate extending over a pair of main girders mutually opposed under the deck plate of a floor slab bridge, and providing a load dispersing member within the space enclosed by the deck plate, the steel bottom plate and the main girders. SOLUTION: A deck plate 18 is arranged on the upper surface of a plurality of main girders 12 juxtaposed in a width direction, and a steel bottom plate 20 connected to each main girder is provided extending over the mutually opposed main girders 12, 12, and a load dispersing member 17 is provided in the space enclosed by the deck plate 18, the steel bottom plate 20 and the main girders 12, 12. When an automobile moves on such a steel floor slab bridge, the load acting on the deck plate 18 through the tires is supported by the reaction from the steel bottom plate 20 through the load dispersing member 17. In the steel bottom plate 20, the load is dispersed more widely by the load dispersing member 17 as it is distant from just under the deck plate 18, so that a small distribution load acts on the steel bottom plate 20.  Accordingly, the deflection of the deck plate 18 can be extremely minimized without providing a reinforcing material, and the manhour for its welding can be reduced.

Title: Microwave detector and method of switching sensitivity of this microwave detector
Inventor: ONO HISAO
IPC: G01S13/60
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To properly switch the sensitivity of a microwave detector and also miniaturize the detector by judging whether high speed traveling or low speed traveling is judged on the basis of the output of an independent sensor, and switching the sensitivity to low sensitivity in low speed traveling to high speed when high speed traveling is switched, and to super-high sensitivity when it is continued for a fixed time. SOLUTION: A traveling state detecting device 10 discriminates whether high speed traveling is performed or not on the basis of the vibration of a vehicle detected by use of a vibration sensor. A control part 12 determines the detecting sensitivity on the basis of the information outputted from a traveling state detecting part 10 and a timer 11 and controls so as to have the detected sensitivity. A damping quantity regulating part 6 forms a sensitivity regulating means. In low speed traveling, low sensitivity is set to make it difficult to detect microwaves so that the wrong detecting is prevented. In high speed traveling, high sensitivity is set. Further, when the high speed traveling is continued for a fixed time, super-high sensitivity is set, whereby a microwave oscillator in a far position can be early and surely detected.  The sensor can be also simplified to attain the miniaturization.

Abstract: PURPOSE:To make sure of the reliability of an engine and its sufficient output by selecting an engine control value according to a knocking state in the engine. CONSTITUTION:The octane value of fuel is discriminated according to a knocking state being detected by a knocking detecting means, and an engine control value in a first area where load is high engine speed is less than the setting one is changed over to such one as conformed to the fuel octane value by a first selector means. Likewise the engine control value in a second area where the engine speed comes to the higher speed side than the first area is changed over to such one as conformed to the fuel octane value by a second selector means. Accordingly, a condition for setting the engine control value as use of high octane value fuel should be set as supposing that a side of the second selector means is a yet lower level in the knocking state as compared with the first selector means.
