PROBLEM TO BE SOLVED: To provide a tactile feedback device for giving realistic touch sensation to the user by stimulating the skin of the user. SOLUTION: The tactile feedback device comprises a housing having one end positioned near the skin of the user in use, an actuator, touch pins and an elastic means. The actuator is mounted inside the housing to convert electromagnetic energy into kinetic energy. The touch pins are mounted inside the housing so as to pop in and out, and the front end thereof is popped out of one end of the housing to contact the skin, and is connected with the actuator so as to be operated by kinetic energy of the actuator. The elastic plates of the elastic means are mounted between one end of the housing and the actuator, and have the touch pins fixedly passing through so as to be interlocked with the touch pins, and when the touch pins pop in, they are elastically deformed to have elastic energy. Thus, the touch pins stimulate the skin of the user by the interlocked structure of the actuator and the elastic means converting electromagnetic energy to kinetic energy, so that it is possible to implement realistic touch sensation.

PROBLEM TO BE SOLVED: To provide a device and a method for mixing microfluids while transferring, or for mixing concurrently the microfluids with a biomolecule while transferring. SOLUTION: This mixing/transferring device for the microfluids is arranged with an electrode pair arranged in parallel with the first electrode and the second electrode having a width wider than that of the first electrode, on at least one or more of inner faces of a fluid transfer route, and an alternating current voltage is impressed to the electrode pair to mix and transfer concurrently the microfluids. In the mixing/transferring device for the microfluids of the present invention, the alternating current voltage is impressed to the pair of electrodes constituted of the relatively narrow electrode and the wide electrode, a complicated flow characteristic is generated by an electrophoretic method, and the microfluids are efficiently mixed and transferred concurrently in a filed of compact medical equipment, compact fluid equipment or the like.

Abstract:
PROBLEM TO BE SOLVED: To provide a new material for a heating resistor which makes the control of its specific electrical resistance value easy in a wide range, has a low temperature coefficient of resistance (TCR) so as to minimize the variation in the electrical resistance value with temperature within a constant range over the use temperature range, and realizes high reliability and a long lifetime by stably maintaining chemical and mechanical characteristics including electrical characteristics while being used repeatedly over a long time. SOLUTION: The heating resistor is constituted by mixing an electrically conductive oxide having electrical conductivity and an electrically nonconductive oxide having an insulating property or electrical nonconductivity.
