摘要:
A chemical reactor comprises a microwave irradiating apparatus and a chemical reaction apparatus. The microwave irradiating apparatus comprises a microwave generator and a microwave irradiating cavity (3). The chemical reaction apparatus comprises a tank (2) and a device for controlling the flow of the material. At least a part of the tank (2) is located in the microwave irradiating cavity (3). The chemical reactor can be used for chemical reactions of all kinds of liquid materials, especially multiphase reactions, multiphase catalytic reaction, and the chemical reaction with its reactive materials having high viscosity, semi-solid phase, and high fouling tendency. When the chemical reaction apparatus is used for chemical reaction for producing gaseous byproducts, it can increase the conversion rate of reactants and the yield of product.

FIG. 1 is a top perspective view of an electric spin scrubber, showing my new design; FIG. 2 is a bottom perspective view thereof; FIG. 3 is a top perspective view showing the electric spin scrubber as it would appear when used; FIG. 4 is a front view thereof; FIG. 5 is a rear view thereof; FIG. 6 is a left side view thereof; FIG. 7 is a right side view thereof; FIG. 8 is a top view thereof; FIG. 9 is a bottom view thereof; FIG. 10 is an enlarged detail view of area 10 in FIG. 1; and, FIG. 11 is an enlarged detail view of area 11 in FIG. 2. The dash-dash-style broken lines in the drawings illustrate the portions of the electric spin scrubber, which form no part of the claimed design. The dot-dash-style broken lines illustrate the bounds of the enlarged areas taken from FIGS. 1 and 2, as well as the original areas of FIGS. 1 and 2 from which the enlargements were extracted. The boundaries form no part of the claimed design.

An egg-drawing toy with an adjustable support spacing, which adopts a vertical structure with two supports, is stable in support, and is suitable for fixing eggs or toy eggs. In addition, the lower support is designed to have an elastic support structure, and the spacing between the upper support and the lower support is adjustable, which is automatically achieved by a compression spring, thereby realizing the support and positioning of eggs with different sizes between the upper support and the lower support, and thus having better universality.

A light-emitting diode (LED) driver provides faster rise and fall times for LED current to reduce image sticking and other interference. A standard DC-DC converter provides a sum current that is slowly ramped up and down by a bypass current digital-to-analog converter (DAC). A digital value to the bypass current DAC is ramped up or down before an LED current is turned on or off. When the LED current is turned on, current is shifted from a bypass path to a path through the LED, maintaining a constant sum current from the DC-DC converter. When a different LED is turned on, current is shifted from one LED's path to the other LED's path. Separate LED current DAC's in each LED path and in the bypass path can share the sum current with digital precision. Using a single DAC for the sum current and switches in each path reduces cost.

Aspects of the present invention provide a disk-to-disk-to-tape backup method and system responsive to a combined backup request to backup a dataset to a backup disk according to a disk backup schedule and then to backup the dataset from the backup disk to a backup tape according to a tape backup schedule. The combined backup method completes a backup of the dataset to the backup disk and then to a backup tape device in accordance with a resolved schedule that considers potential conflicts between the schedules. To restore, aspects of the invention receive a request to restore a backup of the dataset from a backup-tape and the resolved schedule derived from the tape backup schedule and the disk backup schedule. The restoration verifies that a backup tape holds the target dataset by matching a combined backup identifier from the request against a corresponding combined backup identifier held in storage.
