Abstract:
A back scrubber has a base and a cleaning plate. The base has a front basal surface, a rear basal surface and a slot. The slot is formed in the front basal surface and has a slot opening, an inner wall and an engaging structure. The cleaning plate has a front plate surface, a rear plate surface, an inserting member and an engaging member. The front plate surface is uneven. The inserting member protrudes into the slot. The engaging member is formed on the inserting member and engaged with the engaging structure. The back scrubber in accordance with the present invention can be used to effectively and efficiently wash and is capable of saving body-cleansing agent and water.
Abstract:
In a process for producing cyclohexylbenzene, hydrogen and a liquid feed comprising benzene are introduced into a reaction zone and are contacted in the reaction zone under hydroalkylation conditions to produce cyclohexylbenzene. An effluent stream comprising cyclohexylbenzene and unreacted benzene is removed from the reaction zone and is divided into at least first and second portions, wherein the mass ratio of the effluent stream first portion to the effluent stream second portion is at least 2:1. The effluent stream first portion is then cooled and the cooled effluent stream first portion is recycled to the reaction zone.
Abstract:
In a process for producing cyclohexylbenzene, benzene and hydrogen are fed to at least one reaction zone. The benzene and hydrogen are then contacted in the at least one reaction zone under hydroalkylation conditions with a catalyst system comprising a molecular sieve having an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07 and 3.42±0.07 Angstrom, and at least one hydrogenation metal to produce an effluent containing cyclohexylbenzene. The catalyst system has an acid-to-metal molar ratio of from about 75 to about 750.
Abstract:
A multi-band antenna includes a first radiator resonating at a high frequency bans and a second radiator extended from a first end and toward a second end of the first radiator, and resonating at a low frequency range. An opening slot is formed between the first and the second radiators. A connecting slot and an end slot are formed in the second radiator. The width of the connecting slot is wider than the width of the opening slot. The connecting slot can prevent vectors potential caused by the second radiator from being neutralized. The electromagnetic coupling effect over the opening slot caused by the first radiator and the second radiator can pull down the low frequency range for reducing the size of the second radiator. Therefore, the multi-band antenna has a small size.
Abstract:
A signal delaying system is provided, including a delay locked loop circuit and a voltage providing circuit. The delay locked loop circuit delays an input signal to generate a delayed signal. The voltage providing circuit provides a control voltage to the delay locked loop circuit for determining a delay time of the delay locked loop circuit when the delay locked loop circuit operates in a first mode; and providing a stand-by voltage to the delay locked loop circuit when the delay locked loop circuit operates in a second mode, wherein the voltage providing circuit further adjusts the stand-by voltage to make the stand-by voltage substantially equal to the control voltage.
Abstract:
A roller holder includes a number of couplers disposed between two longitudinal rods for coupling the rods together and for forming a number of compartments to receive rolling members, and two retaining devices disposed in each compartment of the roller holder and attached to the rods for retaining the rolling members in the compartments and between the rods and the couplers of the roller holder, and for preventing the retaining devices from being impacted by the rolling members, the retaining devices each include a projected portion located above the rods and a protruded portion located below the rods and the couplers for engaging with the rolling members.
Abstract:
Method for increasing the moisture-proof capability of a chip includes coating moisture-proof glue at the chink of the chip. More particularly, when the packaging structure carries a chink exposed to outside of the chip, the chink is coated with the moisture-proof glue for preventing moisture from entering the internal part of the chip so as to increase the moisture-proof capability of the chip.
Abstract:
A liquid crystal display (LCD) panel having a plurality of pixels includes a first substrate and a second substrate disposed opposite to each other. The first substrate has a common electrode layer which has a first common area and a second common area. The second substrate has a plurality of data lines, a plurality of scan lines, a plurality of signal lines and a pixel electrode layer. The data lines and the scan lines are disposed in array and around the pixels. The signal lines traverse the pixels, respectively. For each of the pixels, the pixel electrode layer overlaps the data line and/or the scan line, and is divided into a first pixel area and a second pixel area by the signal line. The first common area is disposed corresponding to the second pixel area. The first pixel area has a first slit pattern. At least one of the first common area and the second pixel area has a second slit pattern which differs from the first slit pattern in geometry.

The ratio of the total number of moles of hydrogen fed to said at least one reaction zone to the number of moles of benzene fed to said at least one reaction zone is between 0.4 and 0.9:1.
Abstract:
The present invention discloses a quantitative analysis method for microRNAs, wherein a fluorescence-labeled DNA probe, which is equinumerous and completely complementary to a microRNA, hybridize with the microRNA. The products of hybridization include the fluorescence-labeled DNA probe containing 22 nucleotides and the probe-microRNA duplex containing 22 base pairs. The products of hybridization is introduced into a capillary by the pressure difference between two ends of the capillary and the siphon effect and separated by electrophoresis. A laser is used to induce fluorescence from the products of hybridization. Then, the intensities of fluorescence are measured and analyzed.
