摘要:
A micropump comprises a first substrate, a pumping section formed in the first substrate, a second substrate connected to the first substrate and having an inlet port and an outlet port, and at least two valve sections formed in the first substrate for controlling the flow of fluid from the inlet port to the outlet port through the pumping section. The pumping section has a piezoelectric element and a diaphragm for undergoing deformation upon application of a voltage to the piezoelectric element to control the flow of fluid into and out of the pumping section. Each of the valve sections has a piezoelectric element and a diaphragm for undergoing deformation upon application of a voltage to the piezoelectric element. A flow passage is formed in the first substrate for connecting the pumping section and the valve sections in fluid communication. A plurality of packing members are each disposed between a respective diaphragm of the valve sections and the second substrate for blocking the flow of fluid when no voltage is applied to the piezoelectric: elements of the valve sections. The packing members are operative to permit the flow of fluid through the valve sections when a voltage is applied to the piezoelectric elements of the valve sections to cause the diaphragms of the valve sections to undergo deformation and form a gap between each of the packing members and the second substrate or between each of the packing members and a respective diaphragm of the valve sections.

The information recording unit has a memory for firstly storing data, a record medium for intermittently recording the stored data in the memory, a record means for recording the data on the record medium, and a valid-data decision means for determining whether the recorded data is valid. The record means records the data in at least two different areas on the record medium, and the decision determines one valid data among the recorded data in the different areas. The unit includes a record control means for controlling the record means. The record control means provides a control command for the record means to record a predetermined quantity of data stored in the memory at a first recording location on the record medium and also provides a control command for the record means to read the predetermined quantity of the data at least one recording location different from the first recording location after the predetermined quantity of the data is recorded at the first recording location.

An information reproduction unit has a data read means with a pickup for intermittently reading data recorded on a storage medium, a write means for writing the data in a memory, and a reproduction means for sequentially reading out the data written in the memory. The unit also has a defect detection means for detecting a defect of the storage medium during a data read waiting period. The defect detection means may determine the presence of a defect based on a readout result provided by the data read means. The unit may further include a storage means for storing a defect position information. Furthermore, a read characteristic may be adjusted on reading data at the defect position on the storage medium.

A power generator has a power generation unit for generating electric power, a rotary unit and a power transmission unit. The power generation unit includes a stator having a stator core and a rotor disposed in the stator. The rotor has a rotor shaft and a driven gear disposed on the rotor shaft and is configured to be driven to rotate the rotor shaft. The rotary unit has a driving gear for undergoing rotational movement to rotate the rotor shaft via the driven gear to generate electric power. The power transmission unit has an intermediate gear for transmitting a rotational force of the driving gear of the rotary unit to the driven gear of the rotor shaft. The intermediate gear has at least one rotary shaft disposed inside of the stator core.
摘要:
A pump comprises a first substrate having a fluid inlet port for receiving a fluid, a fluid outlet port for discharging the fluid, a first pumping section for pumping the fluid from the fluid inlet port to the fluid outlet port, a first inlet valve section disposed between the fluid inlet port and the first pumping section, and a first outlet valve section disposed between the fluid outlet port and the first pumping section. A second substrate has a second pumping section, a second inlet valve section, and a second outlet valve section. An intermediate substrate is disposed between the first and second substrates to form a first fluid feeding path and a second fluid feeding path for feeding the fluid pumped by the first and second pumping sections. The first fluid feeding path extends from the first inlet valve section to the first outlet valve section through the first pumping section. The second fluid feeding path extends from the second inlet valve section to the second outlet valve section through the second pumping section. The intermediate substrate has a first connection port connecting the first and second inlet valve sections in fluid communication with the fluid inlet port and a second connection port connecting the first and second outlet valve sections in fluid communication with the fluid outlet port.
