A multimedia data recording apparatus is disclosed that enables large-volume recorded data to be recorded for a long period in accordance with the importance of the data, by means of a simple configuration and simple processing, and without imposing a heavy load on the system. In this apparatus, a layer classification section classifies video data captured by a surveillance camera and input via a video processing section into a plurality of layers on a frame-by-frame basis according to importance. A data recording section assigns a file to each layer and records classified data in a data recording medium. If an information amount reduction section detects that the vacant capacity of the data recording medium has reached or fallen below a threshold value, it deletes a frame belonging to the lowest layer among the plurality of layers.

Three-dimensional models can be produced by a sheet deposition method using a sheet material made of water-soluble paper as the depositing material. Each layer of the sheet material is made severable along the contour lines of the three-dimensional model by discharging water using the nozzle of a fluid discharge head onto each layer of the sheet material. A coloring solution is discharged from the fluid discharge head when each layer is deposited to color the sheet material. After the deposition is completed, the unnecessary parts of the sheet material can be pulled away to complete the three-dimensional model. Alternatively, by discharging a setting solution using a nozzle of the fluid discharge head onto each layer of the sheet material, each layer of the sheet material in the section area of the three-dimensional model can be insolubilized, and a color setting solution can be discharged to color and set the colored parts. After the deposition is completed, the deposition can be immersed in water to remove the sheet material that was not insolubilized and complete the three-dimensional model.

A switching power supply apparatus includes a PFM control circuit that outputs a clock signal Set such that a switching frequency of a switching element varies in accordance with a load state. The clock signal Set determines a turn-on timing of the switching element. A reference value of a current flowing through the switching element determines a turn-off timing of the switching element.

Input control is performed separately on the clock signal Set and the modulation signal. Accordingly, even when the clock signal Set and the modulation signal contribute to each other to offset each other, modulation effects are not cancelled.

When a suction button is pushed in a pushing operation direction, the suction button pushes down longer lever ends of inversion levers, shorter lever ends of the inversion levers are pushed up based on a seesaw operation and the principle of leverage, and a piston body coupled through a coupling body moves in a direction opposed to a pushing operation direction against an urging force of a spring in cooperation with this upward movement. As a result, a valve moving portion moves away from a valve receiving portion to open a suction duct valve portion and suction is carried out, but the piston body retires to an outer periphery side of a bent duct when the valve portion is opened, and hence a suction duct is widened, thereby facilitating suction of even, e.g., a fluid having high viscosity.

Next, the negative pressure is applied again at time point 166d for a definite period of time. Thus, the opening in the skin is broadened, which facilitates the flow out of the blood (16).
