A hydraulic power generating device includes a main body case forming a flow passage provided with a water wheel chamber between a fluid inlet port and a fluid outlet port, a cover covering the main body case, a water wheel for power generation disposed in the water wheel chamber, a rotor magnet for rotating in cooperation with the water wheel. An ejection port including a groove is formed on the main body case for ejecting fluid toward the blades of the water wheel at a high speed and an protrusion part is formed on the cover for adjusting the aperture area of the ejection port by entering into the groove. Further, a discharge space is formed at a downstream position of the water wheel chamber so as to be in communication with the fluid outlet port, to which fluid after having rotated the water wheel is ejected and a stagnation preventing protrusion part is formed in the discharge space to facilitate flow of air bubbles to the fluid outlet port.

In order to enhance stability of a discharge lamp at the time of dimming lighting even in the case where a light output is lowered, a direct current superimposing circuit 1 superimposes a direct current voltage on an alternating current voltage applied to a fluorescent lamp FL, and a dimming signal correction circuit K1 receives a detection value of a direct current voltage detection circuit 2 and a dimming signal Vs1 that is from an outside, outputs a dimming signal Vs0 higher in level than the dimming signal Vs1 in the case where the detection value of the direct current voltage detection circuit 2 exceeds a first threshold value Vth1, and decreases the level of the outputted dimming signal Vs0 to the level of the inputted dimming signal Vs1 in the case where the detection value of the direct current voltage detection circuit 2 falls down below a second threshold value Vth2 that is equal to or less than the first threshold value Vth1. Then, an amount of alternating current power supplied to the fluorescent lamp FL by an inverter circuit INV is increased and decreased in response to fluctuations of the level of the dimming signal Vs0 outputted by the dimming signal correction circuit K1, whereby the fluorescent lamp FL is dimmed.

To provide a tactile sensor that allows a contact to be displaced largely and can detect fine ruggedness, flexibility, and other features of a surface of a measuring object.A sensor part S includes a frame 10 that includes a side part of a substrate B, a contact 20 that is disposed in parallel to the substrate B so that a tip of the contact 20 projects from a side face of the substrate B, a suspension 30 that supports the contact 20 to the frame 10, and displacement detectors 41 and 42 each of which detects displacement of the contact 20. The side face of the substrate B functions as a sensing surface. The contact 20 coming in contact with a measuring object O is displaced on a level parallel to the substrate B. Since the sensor part S can be configured widely in a planar manner along the substrate B, the structure has higher flexibility of design. As a result, the sensor part S allows the contact 20 to be displaced largely, and can detect fine ruggedness, flexibility and other features of the surface of the measuring object O.

An inkjet head (1) has a liquid flow path section (3) for receiving liquid and, in response to application of a voltage, ejecting the liquid to an object on which a drawing is to be made. The degree of design freedom of the shape of the liquid channel section (3) or the shape of a liquid channel in the liquid channel section (3) can be improved because the liquid channel section (3) is formed on the upper surface of a substrate. Furthermore, the inkjet head can have a structure corresponding to the properties of liquid to be ejected or to an object to which the liquid is to be ejected.

This high-frequency module has port electrodes (PMan1, PMrH1, PMrH2, PMtH, PMc1, PMc2) which serve as external connection terminals provided on a laminated body of dielectric layers. Port electrode (PMan1) is connected to an antenna (ANT1). Port electrodes (PMrH1, PMrH2, PMtH, PMc1, PMc2) are respectively connected to communication systems having corresponding frequency bands. Port electrode (PMan1) is connected, by means of switch elements (SW1-SW5), to port electrodes (PMrH1, PMrH2, PMtH, PMc1, PMc2). Switch elements (SW1, SW2) and switch elements (SW3-SW5) are unconnected with each other inside a switch circuit (SWIC), and the switch elements can be connected by means of a common terminal (S1) provided outside the switch circuit (SWIC). Thus, the resulting high-frequency module can accommodate a design change using the same switch circuit without modifying the switch circuit.
