A foil-type pressure sensor includes a first foil and a second foil. A spacer is arranged in between the first and second foils, which keeps the foils at a certain distance from each other. The spacer presents an opening that defines a sensing region. In this sensing region, the first and second foils can be brought closer one to the other against the resiliency of the foils by pressure acting on the pressure sensor. The pressure sensor further includes light emitting means arranged between the ...

To be able to measure a value with regard to a dissipation, or a value in proportion to a dissipation energy without making a premise by being brought into a steady state. Exciting means 12 for carrying out an excitation by following a resonance frequency of a cantilever 2, a displacement detector 10 for detecting a displacement of a stylus at a tip of the cantilever 2, an amplitude detector 20 for successively providing an amplitude from a signal from the displacement detector 10, a difference ...

Trays within a given level of a drum-type vending machine form individual zones, and may be further subdivided into additional individual zones, for which pricing may be separately specified. A vend door for the corresponding level is constrained to allow access to a given zone upon payment of the appropriate amount. More levels and greater flexibility in pricing and product selection are thus enabled, together with greater control over vending operations.

A pedal-type exerciser includes a base, first and second drive assemblies, a transmission chain, a pair of elongate pedal members and an elastic cord unit. The base has front and rear end portions. The first drive assembly has a first horizontal axle mounted rotatably on the front end portion of the base, a first drive wheel mounted securely on the first horizontal axle, and a pair of first crank arms mounted securely on opposite ends of the first horizontal axle. The second drive assembly has a...

A heat exchange type ventilator allows preventing its heat exchanger from being clogged with buildup of ice, and also alleviating cold-draft feeling. This ventilator has an exhaust-air coupling section and a supply-air coupling section, and a ventilating unit which includes an exhaust-air outlet and a supply-air inlet, a motor for driving an exhaust-air fan and a supply-air fan, the heat exchanger for carrying out heat recovery between interior air and outside air, and a cut-off damper for cutti...

A V-type engine includes a housing, a crankshaft, a counterbalance shaft, a first camshaft, and a second camshaft. The crankshaft, the counterbalance shaft, the first camshaft, and the second camshaft are rotatably supported by the housing. The crankshaft has a crankpin. In one embodiment, an imaginary plane perpendicular to the rotational axis of the crankshaft intersects each of the crankpin and the counterbalance shaft such that the crankshaft is operatively coupled with each of the counterba...

An inductor-type synchronous machine includes field stators having field elements by which an N-pole and an S-pole are concentrically formed, rotors to which a rotating shaft is fixed and has N-pole inductors disposed so as to face the N-pole of the field elements and S-pole inductors disposed so as to face the S-pole of the field elements, and an armature stator having armature coils disposed so as to face the N-pole inductors and the S-pole inductors.

A leg type mobile robot (R) including an body (R2), legs (R1) each connected to the body (R2) via a first joint (12, 13), and foots (R17) each connected to an end part of the leg part (R1) via a second joint (15, 16), the foot (17) including a foot portion (61) having a lower end part having a ground area (64, 66) grounded on a floor surface, the foot portion (61) including a plate spring part (62) supporting empty weight while bending at the time of being grounded.

An array calculation device that includes a processor array composed of a plurality of processor elements having been assigned with orders, acquires an instruction in each cycle, generates, in each cycle, operation control information for controlling an operation of a processor element of a first order, and then generates an instruction to the processor element of the first order in accordance with the operation control information and the acquired instruction, and also generates, in each cycle,...

A riding-type mower vehicle comprises a mower supported by a vehicle body; a grass collector configured to receive cut grass cut by the mower; a vehicle-side connector located at a rear position of the vehicle body and having a pair of inclined guide portions that face each other such that a distance between the inclined guide portions decreases toward lower portions of the inclined guide portions to open upwardly; and a collector-side connector provided to the grass collector to extend generall...
