A monolithic ferrule / endcap / optical fiber structure is provided wherein an optical fiber is terminated in a ferrule and bonded by fusion to form a monolithic unit which minimizes optical loss and is typically capable of transmitting high power laser radiation, preferably on the order of 500 W and higher, without damage to the optical fiber and ferrule. Ferrule, endcap, optical fiber and fusible powder are composed of material of substantially the same physical characteristics such that, when all are fused together, the structure so formed is monolithic and the optical path is transparent.

The purpose of the present invention is to provide a cooking vessel having a heat source that can be raised or lowered and adjusted to the left and right, comprising the heat source, which can be raised or lowered with respect to the cooking grill plate, for transferring heat to a cooking grill plate thereby adjusting the amount of heat applied to the cooking grill plate. Also, by allowing rotation of the heat source to left or right directions, the amount of heat transferred to the cooking grill plate can be varied when cooking food or meat on the cooking grill plate or after the cooking or grilling of the meat is done, thereby enabling quick grilling of food or meat and preventing burning of the completed food or grilled meat. In addition, the present invention further comprises a power blocker for completely blocking power that is supplied to the heat source, thereby significantly reducing electricity consumption that is unnecessarily consumed.

The invention provides an electric pressure cooker with a cover being conveniently opened. The cooker comprises a cooker body, a cooker cover and a buckling part. The buckling part comprises a movable clamping part arranged on the cooker cover and a fastener located on the cooker body. The cooker cover is buckled with the cooker body through the buckling part. The cooker cover comprises a lining and a lock cover located below the lining. The lock cover rotates so that the lock cover and the cooker body are locked and unlocked. The cooker cover is further provided with a cover-opening assembly which drives the locking cover to rotate. The lock cover is provided with an unlocking part. When the cover-opening assembly drives the lock cover to rotate at the first set position, the lock cover and the cooker body are unlocked. When the cover-opening assembly drives the lock cover to continuously rotate at the second set position, the fastener is acted upon the movable clamping part. The movable clamping part is separated from the fastener such that the cooker cover is opened. The rotation angle at which the lock cover rotates from the first set position to the second set position is Alfa. The cooker cover is provided with an elastic device driving the lock cover to rotate. After the cooker cover is opened, the elastic device drives the lock cover to rotate at the angle of Beta which is less than Afla. The electric pressure cooker with the cover being conveniently opened facilitates opening the cover.

In accordance with one aspect of the invention, there is provided a shading protected solar cell apparatus for use in a solar cell system. The apparatus includes a solar cell having a front side current collector and a back side current collector. The apparatus also includes a bypass diode closely adjacent the back side current collector, the bypass diode having a front side current collector and a back side current collector. The apparatus further includes a first electrical coupling for electrically coupling the front side current collector of the bypass diode to the back side current collector of the solar cell. The apparatus also includes a second electrical coupling for electrically coupling the back side current collector of the bypass diode to the front side current collector of the solar cell, the first and second electrical couplings cooperating to enable a current generated by non-shaded solar cells in the system to be shunted through the bypass diode when the solar cell is shaded. The apparatus further includes a thermal coupling thermally coupling the bypass diode to a back side of the solar cell such that heat generated in the bypass diode due to current shunted through the bypass diode is dissipated by the solar cell sufficiently to avoid burning the solar cell or the bypass diode when the solar cell is shaded.

The invention provides a pot cover and an electric pressure cooker, including a rotating shaft, a limit groove, a cross groove, a cross connecting column, a cleaning brush, a pot cover body, a cavity, a coil tube, a box body, a column and a liquid return frame. The cross groove is provided with On the lower end face of the rotating shaft, the upper end of the cross connecting column is assembled inside the cross groove, the cleaning brush is fixed on the annular side surface of the cross connecting column, and the cleaning brush is assembled inside the pot cover. This design is convenient for the cleaning of the pot cover in the present invention. The upper end of the inner wall of the lid, the coil is arranged inside the cavity, and the upper end of the coil passes through the lid and extends to the upper side of the lid. This design is convenient for the utilization of high-temperature steam. The box body is assembled on the annular side of the upper end of the coil. The upright column is fixed on the lower end face of the box body, the liquid return frame is fixed on the upper end face of the upright column, and the liquid return frame is arranged on the upper side of the coil. high.
