摘要:
An engine balancer includes a pair of balancer shafts and a balancer housing for housing the balancer shafts, and is placed in an oil pan at the bottom of an engine. The balancer housing includes a pair of front and rear bearing walls respectively supporting the balancer shafts with rolling bearings interposed therebetween. The bearing walls of the balancer housing are attached to bearing walls for a crankshaft. The housing body has an aperture at the top thereof. The aperture of the housing body is covered with a plate-shaped cover member thinner than a member forming the housing body.

摘要:
A hot dip coating apparatus enables stable and continuous production of a coated steel strip having a high degree of uniformity of the coating quality over the breadth of the steel strip and clean coated surfaces free of deposition of dross. The hot dip coating apparatus has a bottom slit through which a steel strip to be coated is introduced and pulled upward through the coating tank, and an electromagnetic sealing device which applies a magnetic field to the molten metal in the coating tank so as to hold the molten metal inside the tank. The coating tank is provided at its top with an overflow dam for allowing the molten mental to overflow out of the coating tank. The apparatus also has a molten metal supply system which produces a circulating flow of the molten metal through the coating tank. The molten metal supply system has molten metal buffers which communicate with a molten metal supply passage and from which the molten metal is discharged towards the steel strip.

This invention is a plated steel sheet formed by laminating an iron oxide layer and a plated layer on a steel matrix in this order, in which excellent plating adhesion property can uniformly be given to a full surface of the steel sheet by disposing a connection portion made from a metallic iron or an iron alloy connecting the steel matrix to the plated layer in the iron oxide layer. Particularly, it can provide means for easily forming a plated layer having an excellent adhesion property through hot dipping can be given to steel sheets being difficult to conduct the hot dipping such as high-strength steel sheet, stainless steel sheet and the like.

The invention is a high-strength hot dip galvannealed steel sheet having excellent press formability and plating properties by utilizing Si as a strengthening component, specifying an interrelation between Si and Mn and further specifying an alloying ratio of hot dip galvannealed layer, which comprises C: 0.0005-0.0050%, Si: 0.1-2.5%, Mn: 0.1-2.5%, Ti: 0.003-010%, Nb: 0.003-0.10%, B: 0.005-0.0080%, P: 0.040-0.18%, S: not more than 0.008%, Al: 0.005-0.10%, and N: not more than 0.0060 wt %, provided that Si and Mn satisfy the following equation, and the remainder being Fe and incidental impurities, and has a hot dip galvannealed layer formed on a surface of the steel sheet and having a Fe content of 9-12%, wherein said equation is:1.5 (% Mn)-2.ltoreq.(% Si).ltoreq.2(% Mn) (1).
摘要:
An improved release agent applicator for use with a copying machine having a fixing device for pressure fusing a toner image to copy paper as the paper is passing between a fixing roll and a pressure roll. The fixing roll has in contact therewith a porous sheet or tube of poly(ethylene tetrafluoride) resin through which the release agent is applied to the fixing roll. The porous sheet or tube is installed on a support in such a manner that part of the sheet or tube projects from an opening of the support. The sheet or tube is provided with a backup which prevents the deformation of the sheet or tube. The backup is provided behind the sheet or tube and extends in the direction of rotation of the fixing roll.
摘要:
An apparatus and a method for applying a releasing agent to a fixation roller so that toners are not undesirably built up on the rollers and unwanted spots on a document being reproduced are avoided. The releasing agent includes a polypropylene powder dispersed in silicone oil wherein the powder and oil are heated to raise the powder to a molten state and the powder and oil are then cooled forming fine particles of polypropylene powder that do not tend to float on the top of the silicone oil.
