Abstract: A restrainable manhole, handhole cover and open/close device therewith provides vertical pads at predetermined positions along a bottom edge of a manhole/handhole cover, which are integrally molded with a cover body. This forms an inclined a third edge which is longer than an inner diameter of a manhole/handhole neck such that it can prevent the cover body to bounce up and displace when being overlaid by a vehicle. Furthermore, a plurality of pre-molded flat plates are provided on predetermined locations perpendicular to the neck. A pre-punched hole is provided for each flat plate for accepting the vertical pad of the cover body for restraining the cover body in its position at the same time the cover body is overlaid by a vehicle.

Abstract: An improved method for depositing the polysilicon layer from which a gate pedestal is later formed is described. Deposition takes place in two stages. Initially, the conventional deposition temperature of about 630.degree. C. is used. Then, when the intended thickness of polysilicon has been grown, the temperature is ramped down to about 560.degree. C., without interrupting the deposition process, and growth of the film continues to completion. This is followed by a standard doping step using POCl.sub.3. Polysilicon films formed in this way have been found to have very smooth surfaces because the topmost layer is less subject to uncontrolled grain growth. As a consequence, dielectric layers obtained by oxidizing such films exhibit superior breakdown voltages.

Abstract: A burn-in method for synchronous memory that utilizes synchronous signals for the burn-in operation. Using synchronous clock pulse signals for burning in the synchronous memory is able to exercise the burst output mode and the pipeline function, and hence the optimum burn-in results can be obtained. Furthermore, synchronous burn-in not only can increase the processing speed up to twice the conventional asynchronous burn-in method, but can simulate of the actual working environment of the synchronous memory as well. Moreover, an asynchronous burn-in method can be selected whenever required without any penalty.

Abstract: The present invention discloses a photo-induced DNA-cleaving agent composition comprises N-aryl-N-(alkyl or arylalkyl)hydroxylamine having the following formula: ##STR1## wherein R is C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, phenoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl)wherein R.sub.1 is hydrogen, C.sub.1 -C.sub.6 alkyl, phenyl, C.sub.1 -C.sub.6 alkoxy, C.sub.1 -C.sub.6 alkoxycarbonyl, halogen or halo(C.sub.1 -C.sub.6 alkyl); R.sub.2 is hydrogen; R.sub.3 is hydrogen or phenyl; R.sub.4 is hydrogen, phenyl, hydroxylphenyl, methoxyphenyl, dimethoxyphenyl, dimethylaminophenyl or naphthyl. The present N-aryl-N-(alkyl or arylalkyl)hydroxylamine is stable in dark, but it can react with O.sub.2 to form HO.multidot. radicals under irradiation of UV light for a period of 2-3 hours. The HO.multidot. radicals then react with DNA to accomplish cleavage of DNA.

Abstract: The present invention relates to an adapter, more particularly, to an improvement to an adapter for mobile phone. The adapter generally comprises an adapter housing, a conducting wires, and a microphone housing. The adapter is further provided with speaker and amplifying circuits. The microphone housing includes a housing and a terminal socket which includes a multi-pin terminals for electrical connection with the signal socket of the mobile phone. When the plug of the adapter housing is inserted into the lighter-socket and the multi-pin terminal is connected with a mobile phone, the mobile phone is powered by the lighter-socket via conducting wires. The driver may readily use the mobile phone through the microphone without holding the handset. Characterized in that the fixture of the microphone housing includes a bottom housing and a fixing housing. The bottom housing is provided with a groove having a holding socket thereof.

Abstract: A multipurpose exercise device comprises a dumb bell set, a spring, a resilient tube set, a jump rope, and a plurality of pivoting apparatuses. The component parts of the multipurpose exercise device are so assembled that the exercise device can be used interchangeably as an arm building device, a chest building device, or a jump rope.

Abstract: A pixel block transfer system has a shifter, at least two registers, an extractor and a mask. Parameter evaluation logic is used to generate most of the parameters needed in the pixel block transfer. The start address of the source block, the start address of the destination block, the number of pixels in the source block and the number of rows in the source block are input to the parameter evaluation logic. The parameter evaluation logic then determines the left shift number, the number of read data, the number of write data, the two write flag, the two read flag, the left mask number and the right mask number. The start addresses, the flags and the read and write numbers are sent to a state machine. These are used to control the pixel block transfer. The left shift number is sent to the shifter and the extractor. It signifies the number of pixels to be shifted left. The left and right mask numbers are sent to the mask to control which pixels are masked and, therefore, not modifiable.

Abstract: A display memory architecture which efficiently stores and processes true color and index mode pixels is disclosed. The R, G and B components of true color mode pixels occupy different groups of bit planes in different banks of a frame memory. In addition, consecutive index mode pixels are located in not necessarily consecutive different groups of bit planes in consecutive banks so that a plurality of index mode pixels can be accessed simultaneously in reading and writing operations. Pixel swap circuits are used to swap the order of the R, G and B components of true color pixels and the order of simultaneously accessed index mode pixels, when the order of the accessed locations is different from the order in which R, G and B components of true color pixels or a plurality of index mode pixels are processed by a graphics processor.
