Title: Detecting device for setting state of working cloth
Inventor: ITOU HIROSUMI
IPC: D05B27/22
Filed: 1991-02-08
Abstract: PURPOSE:To automatically detect the setting state by varying a relative feed amount for a transfer of a pair of working cloths, and calculating the magnitude of a variation of a generated true target shift amount. CONSTITUTION:A sewing machine is operated by the upper feed amount X1, and true pattern shifting amount between a pair of working cloths at a first detecting position is calculated. Thereafter, a prescribed distance, for instance, 10cm is sewn, a variation of a shifting amount is obtained by calculating a true pattern-shifting amount again, and a variation Y1 of the shifting amount by the upper feed amount X1. Subsequently, by changing to the upper feed amount X2, a variation Y2 of the shifting amount is obtained in the same way. Next, based on the variations Y1, Y2 of the shifting amount by the derived upper feed amounts X1, X2, a correct feed amount X3 for setting the variation of the shifting amount to zero is derived, and a value obtained by adding a positive constant S to X3 is set to X4. In the same way, a variation Y4 of the shifting amount by the upper feed amount X4 is obtained. Based on these four pairs of data, a setting state alpha on the contracted side, and a setting state betaon the extended side are calculated.

Abstract: PROBLEM TO BE SOLVED: To provide a lead-acid battery with highly rated discharge characteristics enhanced by a method wherein a specific amount of expanded graphite to a weight of active material is contained in positive electrode plate material and/or negative electrode plate material, and in the expanded graphite a sulfone group is coupled to its carbon end. SOLUTION: In a lead-acid battery, expanded graphite in the amount of not more than 5% of a weight of active material is contained in positive electrode material and/or negative electrode material, and in the expanded graphite, a sulfone group is coupled to its carbon end. By treating graphite thermally and by boiling, powder dispersed in sulfuric acid solution, a layer structure of the graphite grows (expands), and a specific surface area becomes large. In addition, the sulfone group is attached to the carbon end in the graphite thus treated, and wettability for the sulfuric acid solution (electrolyte) containing sulfuric acid ion which participates in charging and discharging reaction of the lead-acid battery is enhanced. Furthermore, there is a possibility that the sulfone group attached to the graphite acts as a supply source of the sulfuric acid ion which participates in charging and discharging reaction of the lead-acid battery.

Abstract: PURPOSE:To form an upper layer electrode in a self-alignment manner without using a mask, etc. by plating the surface of a lower layer electrode with gold through an electroless plating method under the state in which the surface of the lower layer electrode is exposed. CONSTITUTION:A gate electrode 5 having W/WSi structure, source-drain regions 6 and an active layer 2 are shaped to the main surface of a substrate 1, a gate section is coated with a silicon oxide film 7, and ohmic electrodes 10 are formed.

Title: Noncontact type static seal
Inventor: NAKAZAWA KUNIYASU
IPC: F04D29/10
Filed: 1987-01-30
Abstract: PURPOSE:To dispense with any pressure rise at the times of starting and stopping, by installing a swell of a taper or a step on a sealing surface of either a ring or a runner or both, in the case of a noncontact type static seal consisting of the resting ring and the rotating runner. CONSTITUTION:A fluid in a seal clearance 9 flows in the same circumferential direction as a direction of rotation owing to its viscosity simultaneously with rotation of a runner 3, and dynamic pressure 13 is generated inside the seal clearance 9 by this flow and form of a sealing surface 16. When there is not differential pressure in the seal, the clearance 9 between sealing surfaces 16 is set up so as to cause power to be produced by this dynamic pressure 13 to be balanced with dead load of a ring 4. The smaller in the clearance 9, the larger in the dynamic pressure, so that the ring 4 is uplifted and restored to the original clearance 9. In contrast to this, the larger in the clearance 9, the smaller in the dynamic pressure, so that the ring 4 goes down with its own weight, returning to the original clearance 9. Thus, the clearance 9 between sealing surface 16 is kept constant. Therefore, even if there is no differential surface at the times of starting and stopping of a rotary machine, sealing can be done.

Filed: 1993-02-05
Abstract: PURPOSE:To keep insulation accurately at a transition recess by forming in the transistion recess an insulating wall which has a thinner part than a collar and which allows the transition of a coil. CONSTITUTION:A transition recess 5 is formed by cutting a collar 3 along the tangent direction of a body 2 from the outer part of it until the bottom of the cutout section is brought into contact with the body 2. In the transition recess 5, an insulating wall 6 is formed. The insulating wall 6 is formed so as to get thinner than the thickness of the collar 3 toward the anticutting direction of the transition recess 5. Therefore, the insulating wall 6 has a slant face 6a. A coil 7 is a winding end section of a coil which has been wound around a winding section 4a many times and is also a winding start section of the coil for the next winding section 4b. The coil 7 is a transistion section which moves in the recess after leaving the former winding section for the next one. The transition section is allowed to move in the recess 5 due to the slant face 6a of the insulating wall 6. By this method, insulation can be kept accurately at the transition recess.

Abstract: PURPOSE:To obtain a color picture tube electron gun electrode structure which has a reduced cost and has reduced graphite separation and spark current by decreasing the number of welding parts extremely. CONSTITUTION:A bulb spacer contact 10 and a shield cup 11 are assembled by fitting spherical-shaped parts 10a of the bulb spacer contact 10 into holes 11a and cuts 11b of the shield cup 11, and welding and fixing the bulb spacer contact 10 to the shield cup 11 at a welding point 12.
