Each pair has facing tubular openings receiving an associated end extent of a rocker rod. Each adapter has a pair of generally rectilinear recesses adjacent to its interior edge, one recess near the top of the tubular opening offset toward the center to a limited extent and the other recess extending laterally from the center for nearly 90 degrees from the top of the tubular opening. A movable locker extends outwardly from each end portion of each tube oppositely from the arcuate extent adapter to be received in the first recesses to hold the rockers downwardly for deploying the playyard in a rocking mode. Each movable locker is adapted to be received in the second recesses with the bar retracted toward the center of the playyard with the legs in contact with the ground for deployment in a fixed mode.

Title: Method for manufacturing tool
Inventor: HU HOU-FEI
IPC: B25B13/00
Filed: 1999-10-25
Granted: 2001-05-28
Abstract: This invention provides a method for manufacturing tool, mainly to provide anti-slippery device to the tool surface. The manufacturing procedures for the anti-slippery apparatus mainly comprises the steps of: proceeding surface finishing of lapping polishing to a metallic tool formed by hardening treatment, to make the whole tool bright as the most smooth mirror due to the tool surface finished by the lapping polishing; electroplating the tool with nickel-chrome to prevent the tool surface from rusting, and to have good appearance, which electroplating a layer of nickel first for rustproof, and then a layer of chrome for wear-resisting; and partially sandblasting the nickel-chrome electroplated surface of the portion need to be applied force and gripped, to make the outer chrome layer rough but not damaged, to form the anti-slippery device on part of the tool. After the lapping polish surface finishing, the added value of the tool is increased, and the tool is easy to clean and not easy for the dirt to adhere. However, because of the property, the tool is slippery and not easy to apply force in the oily working environment. That is why the sandblasting is applied. Therefore, the rough surface is formed on the anti-slippery device surface, to make the tool have larger contact area and better friction, and achieve the functions of effective rustproof and ease to clean at the same time. Another characteristic of this invention is to insert metallic size number on the covering mold before proceeding the partial sandblasting to the tool, and then to proceed the partial sandblasting surface treatment. After the partial sandblasting, the covered size number completes the size marking. The portion been sandblasted appears dark color, while the covered size appears originally bright. Therefore, the size is marked obviously.

Title: Friction resistance generator
Inventor: YAMAJI IPPEI
IPC: F16D7/00
Filed: 1999-12-27
Granted: 2001-12-01
Abstract: The present invention relates to a friction resistance generator capable of always generating a stable frictional force even if the opposed surfaces of a rotary member and a passive member have a curved shape such as a circumferential surface or a spherical surface. In the present invention, when the rotary member is rotated in the predetermined direction while a load is applied to the passive member, the rollers supported rotatably on one of the rotary member and the passive member rotate while being in contact with the rotary member or the passive member, thereby generating a frictional force according to the load on the rollers. In this case, the rollers are installed rotatably on either one of the opposed surfaces of the rotary member and the passive member, and the rollers are arranged so as to be capable of coming into contact with the other of the opposed surfaces of the rotary member and the passive member. Therefore, the rollers can be formed so as to rotate while being in contact with only either one of the rotary member and the passive member, so that the present invention can be applied to the apparatus in which the opposed surfaces of the rotary member and the passive member have a curved shape such as a circumferential surface or a spherical surface.

IPC: H03K5/1532
Filed: 2000-02-02
Granted: 2003-03-01
Abstract: A pulse edge detector for detecting edges of a pulse signal in a bit stream. The bit stream, and herewith the pulse signal, is synchronized to a clock having half the resolution of a clock signal used to transmit the bit stream. Falling and rising edges of the synchronized pulse signal are determined. It is further determined whether the falling and rising edges of the pulse signal fall within a first or a second phase of the clock signal. The determined phase result is recorded for further processing by a succeeding circuit such as a counter. By determination of the pulse phase in both phases of the clock pulse, a double resolution pulse edge detector is obtained.
