Title: Manufacture of spark plug and discharge tip
Inventor: MATSUTANI WATARU
IPC: H01T13/20
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To surely ensure ignitability as well as a long service life by suppressing production of internal cracks of a discharge tip in a spark plug. SOLUTION: An iridium ingot is subjected to hot grooved roll process with plural stages and a hot dice wire drawing process with plural stages to form an wire rod. If the temperature of the roll and the dice is within the range of 710-1,080 deg.C and a wire drawing speed is within the range of 800-1,400 mm/ minute, internal cracks exceeding 0.03 mm is not produced. If the temperature of the roll and the dice and the wire drawing speed are within the range of 710-920 deg.C and 900-1,100 mm/minute respectively, no internal crack is produced. A spark plug having a discharge tip manufactured by cutting this wire rod and attached to its center electrode is excellent in durability.

Title: Film wind spool for camera
Inventor: TEZUKA NOBUO
IPC: G03B17/28
Filed: 1981-09-03
Abstract: PURPOSE:To improve the operational performance for the loading of a film by forming a large diameter part except a small diameter part for taking up a leader part by a projection energized by a spring in a film wind spool for a camera. CONSTITUTION:If a leader part of a film is not correctly set on a small diameter part of a simple film loading spool for a camera around which the leader part is wound by hooking perforations of the leader part to a pawl 4a, the pawl 4a is not correctly engaged with the spool. Therefore, a large diameter d1' permitted at maximum by a space is formed by energizing an elastic piece consisting of a spring in the outside direction so that the leader part is prevented from being put on the spool to correctly lead the leader part to the small diameter part. After completing to wind the film, the elastic piece forms a circle with the same diameter as the small diameter part.

Title: Production of fuel composition
Inventor: SATAKE TAKEO
IPC: C10L1/10
Filed: 1992-04-16
Abstract: PURPOSE:To produce a viscoelastic fluid fuel improved in storage stability, heat stability and combustibility. CONSTITUTION:A separately prepared oil-in-water emulsion fuel consisting of water and asphalt is introduced into asphalt under kneading, and the resulting mixture is kneaded under conditions in which the obtained composition has stringiness. This composition is convertible into a water-in-oil emulsion. An oil-in-water emulsion fuel based on, e.g. asphalt can be improved in its transportability by limiting the adhesiveness inherent in asphalt, though it is still problematic in storage stability and combustibility in a combustion apparatus. Therefore a water-in-oil emulsion is more desirable. By suitably adopting an oil-in-water emulsion or a water-in-oil emulsion as the structure of an emulsion fuel, it can be easily handled in transportation, storage and combustion. Thus, a fluid fuel based on a viscoelastic substance such as asphalt or coal tar pitch can be used for many uses as general-purpose fuels.

Title: Manufacture of magnetic head
Inventor: GOTO SHIGENOBU
IPC: G11B5/265
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from being entrapped into a bond face of a head by using a predetermined sheet glass as a separating layer of the head. SOLUTION: A recording-reproducing head and an erasing head are bonded via a glass separating layer. The separating layer is formed of sheet glass obtained by redrawing. In comparison with a method whereby the glass separating layer is obtained by cutting, grinding and mirror-finishing of a thick sheet glass, a manufacture lead time is shortened. Since the glass separating layer formed by the redrawing method has a good face state, the glass separating layer is of a good degree of cleanness, which prevents air bubbles from being formed at a bonding face between the glass separating layer and the recording- reproducing head, erasing head.
