A carrier plate for growing a thin film on a substrate includes: a carrier plate body including an upper surface side and a lower surface side opposite to each other, and a hole penetrating through the lower surface side from the upper surface side; a plurality of grooves are formed in the side wall of the hole side, and table tops are arranged in the grooves; a plurality of supporting blocks usedfor supporting the base plate are supported on the inner side wall and can be independently detached from the bearing disc body; each supporting block comprises a first part protrusion which extendsfrom the side wall of the bearing disc body to the interior of the corresponding hole and comprises a second part protrusion, and each second part protrusion is inserted into one groove of the corresponding side wall, is supported by the table top in the corresponding groove and comprises a third part connected with the corresponding first part protrusion and the corresponding second part protrusion. One part of each supporting block is designed to be installed in the groove in the inner side wall of the counter bore of the bearing disc, no extra fixing piece is needed, installation and detachment are convenient, the service life of the bearing disc body is prolonged, and the production cost is reduced.

The invention relates to a battery replacement device applicable to an electric vehicle, which comprises a battery box turntable group, a charging rack battery taking and placing device and an electric vehicle battery taking and placing device, wherein the battery box turntable group comprises a plurality of battery box turntables arranged in a line, and the battery box turntables can rotate witha certain angle around axes per se; the charging rack battery taking and placing device is arranged between the battery box turntable group and a charging rack; and the electric vehicle battery taking and placing device is arranged between the electric vehicle and the battery box turntable group. The invention also relates to a battery replacement system with the battery replacement device. In the battery replacement device, two types of battery taking and placing devices are used to be matched with the turntables to ensure that the battery box replacement of the electric vehicle becomes smoother. The entire battery replacement process is smooth and short in time. Because the efficiency of battery replacement is increased, more battery replacements can be completed within unit time, the battery replacement period is shorter, so that a charger can charge completely, and the utilization rate is higher.

An inkjet image forming apparatus includes inkjet heads each of which has two or more nozzle rows from which ink of different colors is injected (each of the nozzle rows includes nozzle holes), a wipe unit that includes wipers and carries out a wipe process to wipe away ink remained on a surface on which the nozzle rows are formed by the wipers, and a flush unit that carries out a flush process after the wipe process by injecting ink from nozzle holes into which ink of different color from color of ink that is injected from the nozzle holes flows during the wipe process. According to the apparatus, an amount of ink consumed in the flush process can be reduced and a replacement cycle of a mist-absorbing material for absorbing ink mists generated during the flush process can be prolonged.

The invention is about a blast furnace casting groove. It is made up of the protecting brick, the carbon material working lining, the casting material layer, the permanent brick lining and the insulating layer. The surface of the tapping groove is made up of the protecting brick, the carbon material working lining, the casting material layer, the permanent brick lining and the insulating layer. The groove can be field mounted; the carbon material working lining can improve the corrosion resistant ability.
