Title: Method and device for inspecting spark plug and spark plug manufacturing method
Inventor: HAMADA TAKAO
IPC: H01T13/58
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To implement a spark plug inspecting method capable of improving inspection accuracy by high-magnification image pickup and performing highly efficient inspection while preventing the lowering of inspection accuracy due to being out of focus. SOLUTION: At the time of performing gap inspection on a multi-electrode spark plug, the location of the tip of a ground electrode W2 is measured in advance as a reference part location prior to an image pickup process. It is assumed that the reference part location varies for every spark plug. Then at the time of image pickup, a camera 40 with an image pickup optical system whose focal length is fixed is positioned so as to be focused on the tip part of an object part of inspection i.e., the ground electrode W2 in reference to information on the measured reference part location. By using a focus-type camera 40, it is possible to pick up the image of the object part of inspection at high magnification and to improve inspection accuracy.  In addition, as the camera is positioned to a location at which focus is achieved for every spark plug W to be an object of inspection, it is possible to prevent the lowering of inspection accuracy due to being out of focus.

Title: Manufacture of spark plug and manufacturing equipment of spark plug
Inventor: HAMADA TAKAO
IPC: H01T21/06
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To accurately control the amount of pressing bending actually executed to an earthed electrode even if the tip position of the earthed electrode in the pressing direction is dispersed between plugs. SOLUTION: In this manufacturing method, contact of a pressing punch 54 with an earthed electrode W2 is detected with a punch contact detecting means (a load cell) 155, and the position of the pressing punch 54 where the contact is detected is set as the pressing stroke starting position. By moving the pressing punch 54 by the set pressing stroke from the starting position, pressing for bending work to the earthed electrode W2 is conducted. Even when the tip position of the earthed electrode W2 in the pressing direction is dispersed between plugs, pressing stroke is set based on the contact position with the earthed electrode W2, and the amount of pressing bending actually executed to the earthed electrode W2 is accurately controlled, and generation of failure of distance between caps is suppressed.

Title: Buffer circuit
Inventor: TAKEDA KOJI
IPC: H03K19/0175
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To provide a buffer circuit with a fast operating speed that causes no ringing or the like. SOLUTION: A common-mode buffer BUF and an inverter series circuit consisting of series connection of two inverters INV1, INV2 are connected in parallel between an input terminal and an output terminal of the buffer circuit. The noninverting buffer has an N-channel MOS transistor(TR) and a P-channel MOS TR, and source of the TRs are connected in common. CMOS inverters are adopted for the 1st and 2nd inverters INV1, INV2. Since this buffer circuit employs only the two inverters and the common-mode buffer, the circuit configuration is simple and the high speed operation is attained. Furthermore, a leading and trailing wave are rounded by the operation of the common-mode buffer BUF and a fault such as ringing and electromagnetic interference is not caused.

Title: Burst test method for large-diameter steel tube
Inventor: KAWAGUCHI YOSHIAKI
IPC: G01N3/00
Filed: 1991-12-27
Abstract: PURPOSE:To reduce a sound of burst without impairing compressibility of a pressure medium and thereby to enable easy execution of a test not affecting factories and dwellings in the neighborhood by making only water spout at the time of destruction by using gas indirectly. CONSTITUTION:Hollow rubber balls are packed fully in a test body prepared by closing up the opposite ends of a large-diameter steel tube 1. When water is injected from a pressurizing port and thereby a prescribed pressure is applied, subsequently, the rubber balls are compressed, the volumes thereof is lessened and the balls sink to the bottom of the test body under their own weights. When destruction is made to occur from a prescribed part in the test body 1, the whole capacity of a pressurizing medium expands with restoration of the rubber balls, the water spouts from a part 2 of occurrence of the destruction and thus destruction being similar to the one of a gas pipeline is reproduced by the energy thereof. Since it is the water that spouts at the moment of occurrence of the destruction, no sound of burst is generated. Therefore a test can be executed irrespective of time and place, in the same way as an ordinary water pressure test.
