摘要:
The present invention provides a method of manufacturing a rocker arm, having a process of rough processing, in which a metallic stock is subjected to compression-forming by cold forging to form a connecting portion, side wall lower portions of two side wall portions, and two projecting portions projecting beyond a rocker arm width outwardly from the side wall lower portions, and to form, at tip ends of the side wall lower portions, two stem guides projecting downwardly lower than a pat surface level of the connecting portion, a process of formation of a side wall, in which at least a part of the two projecting portions is subjected to ironing processing to form side wall upper portions of the two side wall portions, thereby forming the two side wall portions accommodated in a rocker arm width, and a process of working of a stem guide, in which the two side wall portions are subjected to ironing processing from outer surface sides, thereby increasing a projection height from which the stem guides project downwardly.

A boot for constant-velocity universal joint comprises a major-diameter cylindrical portion 2, a minor-diameter cylindrical portion 3 being separated away from and being put in place concentrically with the major-diameter cylinder portion 2, and having a smaller diameter than that of the major-diameter cylindrical portion 2, and an intermediate portion 10 connecting the major-diameter cylindrical portion 2 with the minor-diameter cylindrical portion 3. The intermediate portion 10 comprises a stretchable bellows portion 19 being connected with the minor-diameter cylindrical portion 3 integrally, and a rigidity-producing portion 11 being connected with the bellows portion 19 and the major-diameter cylindrical portion 2 integrally. The rigidity-producing portion 11 enlarges diametrically from the bellows portion 19 toward the major-diameter cylindrical portion 2, and additionally at least an outer peripheral surface 101 of the rigidity-producing portion 11 has a plurality of shoulders 61 in a stepwise manner. By means of the rigidity-producing portion 11, the rigidity at around the major-diameter cylindrical portion is enhanced, and thereby it is possible to suppress deformation at the time of assembling.

A stainless steel material having compositions which contain on the basis of percent by mass, C from 0.04 to 0.12%, Ni from 0 (including a case of no addition) to 5.0%, Cr from 12.0 to 17.0%, N from 0.0 to 0.10%, Si from 0.2 to 2.0%, Mn at 2.0% or less, Cu from 0.0 to 2.0%, P at 0.06% or less, S at 0.006% or less, with residue being Fe and unavoidable impurities. Further, a parent phase has any one of a single phase structure of ferrite phase or martensite phase and a diploid phase structure of ferrite phase and martensite phase. An end of the base material is melt-welded as a joint to form a pipe. The parent phase is provided with carbide uniformly separated at grain boundaries and within grains, with a dissolved amount of C being 0.03% by mass or less.

A battery case of a rectangular battery includes a lid member welded to an opening portion in a main body member. Each opening rounded portion of the opening portion has, in the circumferential direction, a support projecting portion which projects inward over the entire opening rounded portion and which supports the lid member. Meanwhile, in the circumferential direction along an entire opening short side portion, the opening short side portion has a low projecting portion which projects inward at a position lower than the support projecting portion in the depth direction of the main body member.

A disk drive. The disk drive includes a motor, a base to which the motor is affixed, an actuator supporting a head-slider, and an air-flow control component affixed inside the base. The motor is configured to spin a disk. The actuator is configured to access the disk and to rotate about a pivot shaft to move the head-slider. The air-flow control component includes a plate which faces a recording surface of the disk, and a support portion supporting the plate. The thickness of the plate gradually decreases towards an outflow side of the air-flow control component. The bodies of the plate and the support portion are made of resin; and, a surface of the plate is configured to be held at an electrical potential selected from the group consisting of ground potential and a negative potential.

A battery case of a rectangular battery has a main body member that has the shape of a bottomed rectangular tube, and a lid member that has the shape of a rectangular plate. The main body member has a rectangular opening portion that is constituted of opening long side portions, opening short side portions, and opening R portions. The lid member seals the opening portion. The opening portion is configured such that each thickness of the opening R portions is larger than each thickness of the opening long side portions respectively. In addition, the opening portion and a lid peripheral edge portion are welded to each other in an airtight manner along an entire circumference thereof, by an energy beam that is radiated from outside the lid member in a thickness direction thereof.

A bus monitoring security device is connected to a bus, which includes a tool side bus having a tool connection terminal and an ECU side bus. The ECU side bus is coupled with an ECU, and the tool side bus is coupled with a tool capable of communicating with the ECU via the tool connection terminal. The tool side bus and the ECU side bus are separately coupled with the bus monitoring security device. The bus monitoring security device includes: a controller for determining whether the tool being to access the ECU is connected to the ECU side bus, and for restricting transmission and reception of data between the tool and the ECU when the controller determines that the tool is connected to the ECU side bus.
