Abstract: A test circuit includes a scan chain and a wrapper chain. The wrapper chain shifts in a test pattern according a first clock. The scan chain is coupled to the wrapper chain via a logic combination of a circuit under test. The wrapper chain is configured to transmit the test pattern to the scan chain via the logic combination according to a second clock in a capture phase. The wrapper chain includes a first, a second wrapper cell, and an asynchronous register. The first wrapper cell sequentially shifts in two bits of the test pattern in the shift-in phase. The second wrapper cell shifts in the first bit of the test pattern in the shift-in phase. The asynchronous register conducts the first wrapper cell to the second wrapper cell in the shift-in phase, and latches the second wrapper cell in the capture phase.

Abstract: A joint for preventing a water pipe from twisting comprises a hanger screw sleeve, a disk-shaped oil seal, a gasket and a connecting pipe. The disk-shaped oil seal is sleeved on one end of the connecting pipe, and the water pipe is sleeved on the other end thereof. The gasket is disposed between the disk-shaped oil seal and the connecting pipe. The disk-shaped oil seal, the gasket and the connecting pipe are all arranged in the hanger screw sleeve. As the hanger screw sleeve screws into a water pipe base and presses onto the disk-shaped oil seal, the disk-shaped oil seal and the gasket also rotate together with the hanger screw sleeve. This prevents the water pipe connecting to the joint from twisting.

Abstract: An inlet valve explosion-proof structure is provided, and its flow speed of inflow water exceeds in setting values. The force receiving arm of the guide disc body is pressed to closely attach the guide cone portion at the lower side to the edge of the inner ring base portion of the tube combination base body, so that the pilot hole portion of the tube combination base body is sheltered by the guide cone portion to prevent water pipes from exploding due to excessive water pressure or ageing water pipes. Alternatively, it can prevent water faucets from causing water leakage to achieve efficacies of better stable structure and ensuring high usage safety.

Abstract: A water-saving device structure is provided. When the pressure of an entry water is high, a water-barrier sheet body is pressed to cause a downwardly-moved elastic stopping portion to block a water-inflow opening of a water-outflow seat body, so that the water flow is conducted to a water-outflow opening through a water-conducting opening of the water-barrier sheet body. When the pressure of the entry water is low, the entry water is conducted to the water-outflow opening via one path traveling from the water-conducting opening of the water-bather sheet body to the water-outflow opening of the water-outflow seat body and the other path traveling along the clearances of stopping wall portions of the water-outflow seat body, a water-storage circular slot portion, the water-inflow openings of the water-outflow seat body and the water-outflow opening of the water-outflow seat body. Therefore, the outflow water with steady flow rate can be obtained.

Abstract: A planting device includes a plurality of planting bodies. Each planting body has wall holes bottom holes thereon. Each plating body further comprises connection posts, connection holes and stop board at two ends thereof. The connection posts of one planting body are engaged with the connection holes of the next planting body so as to form the planting device. The wall holes and the bottom holes provide better permeability for soil. The present invention has a simple configuration and is convenient for use.

Abstract: A hanging flowerpot structure includes a flowerpot body which has an engaging seat at one side wall and an engaging post at an opposing side wall. Through engagement of the engaging seats and the engaging posts of a plurality of flowerpot bodies, the flowerpot bodies can be connected steady. A hook lug of a rear wall of the flowerpot body is used to hook a wall. An automatic watering hose is engaged in engaging recesses of the two side walls of the flowerpot body to guide water into the flowerpot body. The excess water is drained from a drain hole of a bottom of the flowerpot body to the lower flowerpot body to save water. The present invention is convenient for use and stable in configuration.
