Title: Spark plug
Inventor: MORIYA TORU
IPC: H01T13/20
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To provide a spark plug, easy in manufacture and having no problem about mounting, without the need of making the outer diameter of an insulator extremely small correspondently to the diameter of a plug hole formed in a cylinder head, if it is made smaller. SOLUTION: A spark plug 1 is equipped with an outer tube member 11 covering an outer circumferential surface of a projecting portion 2a from a main metal fitting 3 of an insulator 2 and coupled to the main metal fitting 3 on the end side thereof, and a hexagonal tool-engaging part 13 is formed on an outer circumferential surface of a rear end part thereof. Because the main metal fitting 3 has no hexagonal part formed for tool engagement as in existing spark plugs, the outer diameter of the insulator 2 can be set at a larger value by the amount produced by eliminating the hexagonal part, if the diameter of the plug hole PH is made smaller.  Therefore, mechanical strength and insulation breakdown voltage of the insulator 2 can be sufficiently secured, and productivity thereof is satisfactory because deficiencies hardly happen that difficulty is found in manufacture of a powder molded body by press-molding, etc., and that defects such as a bend area produced at the time of sintering, when the insulator 2 is manufactured by molding/sintering insulating material powder.

Title: Temperature sensor
Inventor: OOHASHI HIKARI
IPC: G01K7/22
Filed: 1978-11-01
Abstract: PURPOSE: To provide a temperature sensor with an enhanced thermal response, lead wires of a thermistor are made of Fe and Ni or an alloy consisting of Fe and Ni.  
     CONSTITUTION: A thermistor 12 and a pair of its terminal platinum wires 12a and 12b are fixed to the internal of a metal cap 10 by using adhesive filler 14. Inside an insulating tube 16, a pair of leads 18a and 18b are extended to connect to the platinum wires 12a and 12b at each of their ends. The leads 18a and 18b are bundles of a number of wires, both consisting of Fe and Ni or alloy of Fe and Ni, convered with layers 20a and 20b. This structure reduces heat conductivity of the leads 18a and 18b, prevents heat added to the thermistor from being dissipated through the leads 18a and 18b and thus enhances the speed of thermal response.

Title: Method of mounting armature coil
Inventor: SEGUCHI MASAHIRO
IPC: H02K15/09
Filed: 1989-05-26
Abstract: PURPOSE:To prevent an insulating core from deforming by stopping a pressing plate near the end face of an armature core by a guide member provided at the end face of the core when an armature coil is inserted into the slot of the core. CONSTITUTION:A guide member 10 having equal outer diameter C to the outer diameter B of an armature core 2 is pressed to the end face 9b of an insulating core 9 provided at the end face 2b of the core 2. An armature coil 4 is inserted into the slot 5 of the core 2, and a pressing plate 7 is pressed from above to be filled. In this case, the outer diameter B of the core 2 is set to the same size as that C of the member 10. Thus, a stress concentration at the corner 2a of the core 2 by the pressing force of the plate 7 is avoided. Accordingly, the noncontact state of the coil 4 with the core 2 at the adhered part of an insulator 6 with the core 9 is obtained. That is, since the guide member stops the pressing force of the plate at the end of the core, the deformation of an insulating core can be prevented.

Title: Manufacture of oxygen partial pressure detecting element
Inventor: OOTANI MITSUHIRO
IPC: G01N27/12
Filed: 1979-10-17
Abstract: PURPOSE: To obtain an oxygen partial pressure detecting element having an excellent durability, by securing an assured carrying of the catalyst which makes the exhaust gas component oxidized into the element which receives no intrusion of the impurity.  
     CONSTITUTION: In the process to produce the raw ceramic formed substance by joining several sheets of the raw ceramic plates together in such way that the electrode is sandwiched between the raw ceramic plates, the catalyst is applied on the junction surface of the above ceramic plates composed of the TiO 2  to give oxidation to the exhaust gas component. In this case, the catalyst uses the solution obtained by dissolving the platinum catalyst (HPtCl 6 .6H 2 O) into the solvent (acetone) which dissolves even the organic binder (butyral resin) contained in the raw ceramic plate. After this, these raw ceramic plates are jointed together with the electrode held between to form the raw ceramic formed substance. And this formed substance is burnt to obtain a unified-structure ceramic element carrying the above-mentioned catalyst within a sintered substance.

Title: Network flow analyzing system
Inventor: FURUMURA FUMINOBU
IPC: F17D1/00
Filed: 1979-10-22
Abstract: PURPOSE: To make it possible to derive the maximum flow rate at a high speed, by deriving the capable flow rate in order at every node in the down direction from the departure node to the destination node, and deciding the capacity required for every other path.  
     CONSTITUTION: For instance, the maximum flow rate between the nodes B, G is derived. The shortest path is a path of B-D-G. The capacity of the path of B-D-G is limited to the smaller capacity between the arc bd and dg. In case of arc capacity bd>dg, the capacity of the path of B-D-G is made the arc capacity dg. Therefore, the value of the arc capacity dg is stored in the flow rate register. Subsequently, in case of deriving the remaining path, the capacity of the arc dg is zero and that of the arc bd becomes bd-dg. Accordingly, the flow rate as to the next path is derived by giving this condition to the network, and it is added to the flow rate register. Said operation is continued until a flow between the nodes B, G is gone.
