In order to solve the problem of low accuracy and efficiency of the traditional method, the invention provides a method for confirming positions of upper and lower jaws by adopting a 3D printing complete denture individual tray. An upper jaw individual tray (1) which is manufactured in the manner of 3D printing is compounded with a gothic arch tracing plate (2), a lower jaw individual tray (4), a gothic arch guide plate (6), a preformed tracing screw (5) and a preformed fixing ring (7). The individual tray is combined with an intraoral gothic arch and is formed at one time in the manner of 3D printing, so that the manufacturing of the individual tray is more simple, convenient and accurate, the mounting and debugging of the gothic arch are avoided, the clinic operation is greatly simplified and a beginner also can skillfully use the gothic arch for confirming the horizontal jaw position relation. Meanwhile, the manufactured individual tray can be utilized to manufacture the final impression.

The invention discloses a ventilating and sound insulating secondary frame sectional material which comprises a ventilating frame (2) embedded into an upper wall body (1), and an embedded frame (4) embedded into a lower wall body (3), wherein the ventilating frame (2) and the embedded frame (4) are fixedly connected to form a hole frame. According to the ventilating and sound insulating secondary frame sectional material, the structure in combination of the embedded ventilating frame and the embedded frame is adopted and effectively improves the tightness of the whole secondary frame sectional material and the installing wall bodies, and the problems of the prior art that the crack and water penetrating are generated during arranging a ventilating window can be effectively avoided; the ventilating and sound insulating secondary frame sectional material is convenient to arrange; the secondary frame sectional material is organically combined with a ventilating unit through the structure; and the defects of current double-layer ventilating sound insulating windows that a relatively large space is occupied, the cost is high, and the efficiency is low are overcame.

The invention relates to a self-propelled road milling machine comprising a machine chassis (2), inside of which a milling roll (4) is rotationally mounted between lateral plates (12, 13) that are orthogonal to the axis of the milling roll (4). This milling roll (4), which has a roll base body (14) and a milling tube (10), can be driven via a drive device (6), which is mounted on the exterior of the input-side lateral plate (12), and via a reduction gear unit (8). The lateral plate (13), which is provided for exchanging alternatively mountable milling tubes (10) of different milling widths and which is situated opposite the input-side lateral plate (12), can be easily detached and defines the null side of the machine (1) against which the face of the milling roll (4) rests in an approximately flush manner. In order to enable a milling that is near the edge, the invention provides that the reduction gear unit (8) is mounted on the input side, and that the reduction gear unit (8) comprises an output element, which is mounted on the interior of the input-side lateral plate (12) and whose outer surface (25) forms a seat for milling tube elements that can be slid thereon from the null side. In addition, the invention provides that the roll base body (14) is coupled to the reduction gear unit (8) via the free face (23) of the output element without preventing the milling tube elements from being slid on.

Respective portions to contact a shaft do not contact the shaft in a stable condition. At least three projections 3, 3 a, . . . are formed in an inner periphery of a C-shaped base material 2 that has an opening portion 1 at one place of an outer periphery that expands toward the outer circumference, and spaces between the adjacent projections 3, 3 a, . . . are made inner notches 5, 5 a, . . . . Inner edges of the projections 3, 3 a, . . . are shaped like a convex circular arc circumscribed to an outer circumferential surface of a mounting region of the shaft S. Thus, the respective projections 3, 3 a, . . . can abut the shaft at one point, so that the retaining ring for shaft of the present application can be mounted to the shaft in a good posture.

The invention discloses a foreign matter collecting device and a washer applicable to the device. As being arranged at the inner side of the wash bucket, the filtering device can prevent the losses of the washings or the filtering device caused by the direct contact with the washings, and also can make the washer be more artistic on visual effect. As the foreign matter collecting device forms a group of components, the mounting and dismounting work becomes comparatively easy, and the convenience is also improved when in use. Furthermore, the flowing direction of the washing water can be adjusted so as to increase the washing water volume passing through the foreign matter collecting device; at the same time, the foreign matters in the washing water can be prevented from inserting into the gaps on the stream so as to improve the washing effect.

The invention relates to the technical field of solar photovoltaic application, and particularly relates to a photovoltaic module installation device. The device comprises an adjusting mechanism and two supporting beams. The two supporting beams are used for installing a photovoltaic module. The adjusting mechanism is respectively connected with the two supporting beams and is used for adjusting the distance and / or the angle between the two supporting beams. The photovoltaic module installation device can be adapted to install photovoltaic modules of different shapes and sizes through adjusting the distance and / or the angle between the two supporting beams according to installation conditions. The photovoltaic module installation device can be produced and assembled in a factory accordingto the conventional design, and then transported to an installation site to install photovoltaic modules at the installation site. The whole installation process is simple and rapid, wherein only thematched adjustment is needed, and no professional calibration is needed. In addition, the photovoltaic module installation device is simple in structure, and high in universality and practicability. When the photovoltaic module installation device is made of lighter materials, the photovoltaic module installation device can be installed on conventional roofs. Moreover, the photovoltaic module installation device can also be installed on light steel-tile roofs with the load-bearing requirement.

The invention discloses a safe storage and selection method and device for messages in an LEU (Line-side Electronic Unit) and belongs to the field of data security. A safe selection method for the messages in the LEU comprises the following steps of: extracting a code bit value of each transponder corresponding to the LEU from received real-time security data; sequentially reading message information of each transponder from a safe storage device, and sequentially judging whether the messages meet requirements according to the code bit values; if the messages do not meet the requirements, continuously reading the next message and carrying out judgment; and if the messages meet the requirements, verifying the messages, and outputting the messages to the transponders after verification. According to the method and device disclosed by the invention, the corresponding messages can be selected from message data stored in the LEU by analyzing interlocked data interlocked and sent by a computer, and meanwhile, the validity and the security of the messages in a selection process can be guaranteed; and furthermore, the security of the messages stored in the LEU is improved, so that the message data stored in the LEU and the message data transmitted to active transponders are further guaranteed to be safe and reliable.
