A timepiece with automatic time setting and speed adjusting system can, thru the dial telephone line, call the standard time repeat station to check the standard telephone system standard time. When receiving the time announcement signals from the time repeat station, a separation circuit and a voice signal identification circuit pick up the time calibration signal to calibrate the time and adjust the speed of the timepiece automatically. At the same time, a time differential signal is transmitt...

A combining structure for toy blocks, forming a cross-shaped tenon on the top surface of a single unit block and mortises in the bottom surface of the single unit block, the unit blocks able to be combined together one by one inserting the tenon of a block in the mortises of another block.

A toy fishing play unit with multiple turning discs containing a base plate mounted with a big turning disc provided with a number of recessed holes for settling therein small turning discs which can be turned around simultaneously together with the big turning disc by a motor by means of transmitting gears set among those turning discs.

A combined chain wheel and chain guard assembly is constructed from a single piece plate member which is formed, by stamping or the like, into a hub portion, two radially spaced annular members substantially lying in the same plane as the hub portion, an outermost rim member which serve as a chain guard radially spaced from the annular members and offset to the plane of the annular members, and radial strip members interconnecting the annular members and the outermost rim member. The perimeters ...

A doll catching toy has a turning disc, which is rotated by a mechanism set in a receptacle on which the turning disc is fixed. On the turning disc are fixed capped doll containers, whose caps are opened up or closed down at intervals during the time when the disc is rotating, thus permitting a player to fish up a doll by a magnet or hook attached to a line.

An automatic switch is provided which includes a motion detector, a filter and amplifier circuit, a direction discrimination circuit and a processing circuit for controlling electrical load such as lights or home appliances in a room. The motion detector employs a pyroelectric infra-red detector for detecting the number of persons entering and leaving the room. The detector sends signals with phase differences to the processing circuit for counting. When the number of persons entering the room i...

The present invention discloses a shockproof mechanism for a disc drive. The disc drive includes a tray and a chassis. The tray has a track thereon, and the track includes a first end and a second end. A shaft is disposed on the chassis and engages with the track. When the tray is driven into the disc drive, the shaft moves from the first end to the second end. A block is disposed near the second end of the track for preventing the shaft escaping from the track through the second end.

The present invention discloses a disk drive with ejecting function. The disk drive has a tray that is selectively received in a housing. The tray has a track with a first end and a second end. A chassis is located inside the housing, and a cam rack is slidably disposed on the chassis. A first shaft and a second shaft are disposed on the chassis, and the first shaft engages with the track. A curved bar is slidably disposed on the chassis and touches against the second shaft. When the curved bar ...

A contractible two-sided warp knitting fabric structure includes a front base fabric, a rear base fabric, and a connecting yarn coupled with the front and rear base fabrics. The symmetrical front and rear base fabrics include a first warp knitting yarn and a second warp knitting yarn knitted transversally and longitudinally to produce a plurality of continuous interlacing long meshes for effectively enhancing the extendibility of the warp knitting fabric structure.

A sealed packing box having a size checking space comprises a front portion and a rear portion abutting against and connecting with each other, the front portion is a transparent plastic housing, and the rear portion is a sheet member capable of abutting against and connecting with the front portion; the sealed packing box after being assembled has a first receiving space to completely seal a product packed, and a second receiving space as a size checking space to check whether a product packed ...
