Abstract: An auto steering wheel lock is provided which has a locking set and which is connected with the steering wheel by means of a gripping trench and an auxiliary block, and is blocked with the outside of the instrument panel by means of a blocking rod. The position of the auxiliary block can be adapted for various steering wheels of different sizes by means of an elastic element. The locking set mainly includes a lock and a lock rod, which has a flat recess for engagement by a blocking pin when turning the lock and so obstruct the lock rod from withdrawing.

Abstract: A shock absorbing frame structure including a frame rod having one end inserted into one pocket of the cover sheet of a kite, a sleeve sleeved onto one end of the frame rod, an end cap fixedly fastened to one end of the sleeve outside the frame rod and disposed within the pocket of the cover sheet of the kite, and spring means mounted within the sleeve and stopped between the end cap and the frame rod and adapted for absorbing shocks.

Abstract: The present invention relates to a switch for computer peripheral devices, which is connected between the printer port of personal computer and a printer or a scanner. That is to say the personal computer transmits instruction signals to the switch for computer peripheral devices through the printer port according to the requirement of usage and signal linkage of the peripheral devices such as a printer and a scanner. The switch of the computer peripheral devices order the printer port to connect and communicate with the printer, scanner and other computer peripheral devices for the data input and output transmission, so that when the printer and the scanner are in operation, the computer form a information linkage and transmission structure according to the control of the instruction signal.

Abstract: A disk carrier including an upper carrier plate and a lower carrier plate fastened together by hooks, the upper carrier plate and the lower carrier plate defining a diskette holding chamber for holding a diskette, and a front access hole in front of the diskette holding chamber for access to the diskette holding chamber, the upper carrier plate and the lower carrier plate having a respective circular recess at an outer side for holding a compact disk or video disk, and a respective disk keeper raised from the center of the respective circular recess for keeping a compact disk or video disk in the respective circular recess.

Abstract: A magnetic adjustable loading device with eddy current comprises a flywheel and a rotor made from metal conductor. A stator comprises with a magnetic plate and permanent magnet. By changing the air gap between the rotor and stator, the magnetic flux density is changed. Characterized in that the axial displacement of the stator is replaced by a stator which performs the radial displacement. The loading or resistance can be adjusted in a stepless manner. The overall dimension of the loading device can be reduced and it can be applied in a more flexible and subtle way.

Abstract: An electric water heater including a control unit, and a heating unit having a water container and an electric heating coil inside the water container and being controlled by a control unit, wherein a perforated heat-conductive cylinder is mounted inside the water container around the electric heating coil to separate the inside space of the water container into a heating chamber on the inside and a pre-heating chamber on the outside; a perforated heat-conductive collar is mounted around the cylinder to separate the pre-heating chamber into a primary pre-heating chamber at the bottom and a secondary pre-heating chamber at the top; the solid-state variable resistor of the control unit has a heat sink attached to a water accumulation chamber of the cold water pipe which guides cold water to the primary pre-heating chamber, which heat sink transmitting heat from the solid-state variable resistor to cold water in the water accumulation chamber.

Abstract: A lamp socket and plug assembly which includes a plug holder, an adapter mounted in the plug holder, a plug coupled to the plug holder and turned horizontally by the adapter within 90.degree. relative to the plug holder, and a lamp socket pivoted to the adapter to hold a lamp bulb and turned vertically within 90.degree..
