A rapid-discharge-valve structural body () allows air to flow from an input-side space (A) to an output-side space (B) in accordance with the flow rate of air to be supplied to a supply passage (). Accordingly, the flow rate of air to be discharged from a discharge passage () also changes. As a consequence, flow rate peaking can be prevented.

Rapid-discharge-valve structural body and diaphragm pump

A diaphragm pump includes a quick discharge valve unit that comprises a vessel including a supply passage, a check valve seat, a delivery passage and a discharge passage, and an elastic member configured to partition an internal space of the vessel into an input-side space connected to the supply passage and an output-side space connected to the delivery passage and the discharge passage. The elastic member includes a check valve body to prevent an inflow of air from the output-side space to the input-side space, and a discharge port valve body configured to close the discharge passage when air is supplied to the input-side space through the supply passage. The vessel includes a connecting path having a sectional area smaller than an area of a section of the supply passage, and configured to release pressurized air in the input-side space to an outside.

A light source apparatus includes a plurality of light source units, a sensor unit, and an interval control unit. The sensor unit is capable of receiving a plurality of emitted light beams from the plurality of light source units and sampling intensities of the emitted light beams at a predetermined sampling interval. The interval control unit is capable of controlling the predetermined sampling interval on the basis of an output characteristic relating to each of the emitted light beams from the plurality of light source units.

Light source apparatus and image display apparatus

This invention provides a diaphragm pump that decreases the number of components or improves workability in assembling. A crank () to which the output shaft () of a motor () is pivotally attached has, in its upper surface, a ring-shaped insertion groove () with respect to the output shaft () as the center. A projecting driving shaft () is formed integrally with a driver (). When the lower end () of the driving shaft () is inserted into the insertion groove (), the axis () tilts. When the crank () rotates, an engaging portion provided in the insertion groove () engages with the lower end (). The driving shaft () rotates while changing the tilt direction of the axis () following the rotation of the crank (). Hence, when a diaphragm portion () attached to the drive element () of the driver () moves upward/downward, a pump chamber () expands/contracts so that a pump action is obtained.

A plurality of data items are received in each frame period, and a digital signal processor (DSP) checks a flag corresponding to each data item in each frame period before the DSP applies processing to the received data. When the checked flag allows the corresponding data item to be processed, the process is performed. When the execution of the process is finished, the flag is reset. When all the flags are reset, the DSP enters a sleep state.

A pump includes a pump chamber, a reciprocally, driven body that is moved to perform a pumping function by changing the capacity of the pump chamber, and a driving mechanism that reciprocally moves the driven body. The driving mechanism includes a rotating plate which is fixed to an output shaft of a motor and has an annular groove therein. A ball is sandwiched between an annular groove of a driving plate and the annular groove of the rotating plate. When the rotating plate begins rotating, the ball moves in the annular grooves and changes the inclined direction of the driving plate, thus, causing the driven body to reciprocate.
