The invention described herein pertains to substituted azaindenoisoquinoline compounds, in particular 7-, 8-, 9-, and 10-azaindenoisoquinoline compounds, which are inhibitors of topoisomerase I, processes and intermediates for their syntheses, pharmaceutical compositions of the compounds, and methods of using them in the treatment of cancer.

An electrode body, which includes a positive electrode plate and a negative electrode plate, includes a positive-electrode tab group that is composed of a plurality of positive electrode tabs. The positive-electrode tab group is disposed between a sealing plate and an electrode body, and a positive-electrode current collector includes a base portion and a tab connection portion that is folded from an end of the base portion. The base portion of the positive-electrode current collector is connected to a positive electrode terminal, and the tab connection portion of the positive-electrode current collector is connected to the positive-electrode tab group. A fuse portion is formed in the positive-electrode current collector, and a first-insulator second region of a first insulator, which is connected to an inner insulator, is disposed between the base portion and the tab connection portion.

A main body of an electronic part has multiple electrodes, to which multiple terminals are respectively connected. The terminals include a normal terminal and a fuse terminal, each of which extends from lands formed in a printed board so as to hold the main body at a position above and separated from a board surface of the printed board. The fuse terminal has multiple leg portions divided by slits. A first leg portion forms an electrical path portion having a cut-off portion, a width of which is smaller than that of other portions of the electrical path portion. A second leg portion has a first supporting leg and a second supporting leg, which are arranged at both sides of the first leg portion. Each of the supporting legs is connected to each of dummy lands formed in the printed board.

The invention relates to an ozone generator of a bionic cellular type discharge unit nesting structure. The ozone generator comprises a horizontal barrel body, wherein end covers are connected at the two ends of the barrel body, respectively; two fixed disks are vertically arranged in the barrel body; a discharge chamber is formed between the two fixed disks; an oxygen gas chamber and an ozone chamber are formed between the two fixed disks and the end covers at the corresponding ends, respectively; at least one cellular type discharge module with a plurality of cellular type discharge units is arranged in the discharge chamber; the two end parts of the cellular type discharge unit are nested on two fixed plates, respectively; the two end parts of the cellar type discharge module are nested on the two fixed disks by the two fixed plates, respectively; each cellular type discharge unit comprises inner electrodes, an insulation tube and outer electrodes which are nested from the inside to the outside; and the inner electrodes and the outer electrodes in each cellular type discharge module are electrically connected, respectively. The ozone generator of the bionic cellular type discharge unit nesting structure comprises a plurality of electrodes, is small in size, large in unit set yield, easy to produce, install and maintain, adjustable in ozone yield and unnecessary to stop during a maintenance process.

The invention is a single use delivery device capable of delivery of an agent (e.g., vaccine, drug, medicament, etc.) in a controlled manner and without requiring specialized skill in administering delivery of such agent. The delivery device is configured to be filled on-site and in the field with a dose of an agent, while remaining sterile and preventing the potential for contamination during thefilling process. The delivery device is further configured to be rendered incapable of reuse following receipt of a fluid agent from a source and subsequently following its intended use of deliveringthe fluid agent to a patient, thereby preventing reuse of the device and reducing the risk of the spreading blood-borne diseases through reuse.

The invention provides a cake blank forming and slitting machine for food processing and a forming and slitting method thereof, and relates to the field of food processing. The cake blank forming andslitting machine comprises a bearing frame and windows; the windows are fixed at front and rear ports of the bearing frame, and a driving unit is arranged on the rear side of the bearing frame; a forming and slitting assembly is arranged in the bearing frame, and the driving unit penetrates through the window to be connected with the forming and slitting assembly; the forming and slitting assemblycomprises a ring sleeve, the ring sleeve is arranged in the bearing frame, the rear end of the ring sleeve is a dense end, and a plug disc is embedded into the front end of the ring sleeve in a sealed mode; four inserting plates are annularly distributed on the surface of the ring sleeve at equal intervals in a penetrating mode, sealing sleeves are arranged at the tangent positions of the inserting plates and the ring sleeve, and the sealing sleeves are embedded into gaps between the inserting plates and the ring sleeve; the reconnection of the cake blank after cutting is caused; meanwhile, on the basis of blowing of cold air to a cake blank, the whole cake blank is in a compact shape, and thus the problem that the shape of the cake blank with the large water content is difficult to maintain when the cake blank is placed in a container, and consequently forming is difficult is solved.

The invention provides an electric fuse structure which comprises a substrate, an insulating layer located on the surface of the substrate and an electric fuse located on the surface of the insulating layer, and the electric fuse comprises a first electrode, a second electrode and a plurality of connecting fuses connected with the first electrode and the second electrode. The plurality of connecting fuses are connected in parallel between the first electrode and the second electrode, even if one or two connecting fuses are in a high-resistance state due to the reason of a manufacturing process, the plurality of connecting fuses are connected in parallel, so that the first electrode and the second electrode can still be kept in a good connection relationship; therefore, the stability of the electric fuse structure can be improved, and the situation that the electric fuse structure fails due to uneven manufacturing procedures is effectively prevented.
