The present invention is a wall hydrant box having a unitary front plate welded onto a front portion of the wall hydrant box. The unitary front plate is sufficiently sized to allow a ring or any other such structure to be mounted to a rear portion of the wall hydrant box, so that the structure is obscured when the wall hydrant is viewed from the front. The unitary front plate also provides a uniform and aesthetic look to the front of the wall hydrant box.

The invention discloses pig-blood balls and a production method thereof. The pig-blood balls comprise fresh pig blood, soy isolate proteins, pig lean, frozen fat and auxiliary materials and specifically is prepared from the following ingredients in parts by weight: 15-20 parts of dehydrated cooked pig blood, 45-50 parts of emulsified material, 30 parts of pig lean, 3.7-6.4 parts of auxiliary materials and 3 parts of water. The production method comprises the following steps of: selecting raw materials according to the ingredients in the formula at first, and then pre-treating pig blood to obtain cooked pig blood and dehydrating the cooked pig blood; emulsifying, chopping and mixing the soy isolate proteins and smashed fat so as to change the soy isolate proteins and smashed fat into the emulsified material; and then placing the pig lean in a chopping and mixing device, chopping and mixing the pig lean at a high speed to obtain fine smashed material, then adding the dehydrated cooked pig blood, the emulsified material and the auxiliary materials, and continuing chopping and mixing at a high speed to obtain a uniform mixture; finally guiding the mixture into a shaping die for forming, and roasting to prepare the formed pig-blood ball products.

A shield plate fixing device of an electronic apparatus includes a mechanical section for performing operation in a main body housing, an electronic substrate for controlling operation shielded by two upper and lower shield plates above the mechanical section, and an upper housing for sealing an upper opening of the main body housing above the electronic substrate. The mechanical section, the electronic substrate, and the upper housing are respectively placed in a stacked manner. The upper shield plate is directly fixed to the main body housing, so as to reduce tolerance accumulation in the assembled electronic apparatus.

The invention discloses a preparation method for back contact type silicon solar cell, which comprises the following steps of: (1) etching texture on the illuminated surface of silicon chips, and setting holes; (2) coating, diffusing and forming junctions on the illuminated surface of the silicon chips; forming PN junctions on the illuminated surface and in the holes; (3) setting transparent heat conducting film on the PN junctions on the illuminated surface and in the holes; (4) etching the circumference; plating antireflection films on the transparent heat conducting film on the illuminated surface of silicon chips; and (5) preparing through hole electrode, back metal electrode and back passivation field on the non-plating film surface of the silicon chips to obtain the back contact type silicon solar cell; and the through hole electrode is electrically communicated with the transparent conducting film. The illuminated surface of the back contact type silicon solar cell is not covered by electrode, so shading loss is avoided and the photoelectric conversion efficiency is greatly improved. The quantity of to-be-opened holes is greatly reduced so as to dramatically reduce the fragmentation rate and simplify the preparation processes.
