摘要:
This invention provides a display device and a display method in which a light source irradiates a light transmitting member with light, the light transmitting member outputs a light component having directivity as display light, and the behavior of this light at the interface between a light transmitting material and the light transmitting member is switched between total reflection and transmission by changing the contact state between them, thereby changing the intensity of the display light.

An electrostatic actuator includes a waveform output register which generates waveform data having a drive time and a drive pattern on the basis of an operation request from the outside and has queues 0 and 1 to 3 holding the waveform data, a waveform data management unit which erases the waveform data held in the queue 0 of the waveform output register after the drive time has elapsed and moves the waveform data held in the queues 1 to 3 to the queue 0, an output waveform generation unit which generates a corresponding waveform signal on the basis of the drive pattern held in the queue 0 of the waveform output register, and a switching circuit which converts the inputted drive pattern into voltage to electrode substrate.

An electrostatic actuator includes a stator having an electrode substrate, a movable unit having a movable element and an electrode arranged opposite to the electrode substrate, a plurality of first operation modules each of which issues an operation command for realizing a first operation, a plurality of second operation modules each of which issues an operation command for realizing a second operation, a module selector which selectively enables one first operation module of the first operation modules and selectively enables one second operation module of the second operation modules, an actuator drive module which generates a waveform signal on the basis of the operation command from the enabled first operation module and the operation command from the enabled second operation module and a switching circuit which converts the waveform signal into a voltage to apply the voltage to the electrode substrate.
摘要:
An electrostatic actuator comprises first and second stator sections having a first electrode array arranged in a first direction, and a second electrode array of electrodes extending in the first direction, respectively. A movable section having fifth and sixth electrodes arranged to face the first and second electrode arrays, respectively, is arranged between the first and second stator sections. A driving circuit alternately performs a first driving operation in which a DC voltage is applied between the adjacent electrodes of the first electrode array and a second driving operation in which a DC voltage is applied between the electrodes of the second electrode array. The voltage application is successively performed by deviating the positions of the electrodes to which the voltage is applied so as to move the movable section in the first direction while vibrating the movable section between the first and second stator sections.

The magnetic recording reproducing apparatus is of a type in which magnetic tape is loaded approximately parallel to a reference plane of a cassette, and in a tape guide group on magnetic tape take up side of a rotary head drum, a first take up side inclined guide on which magnetic tape is wound around immediately after it moves away from rotary head, a take up side guide roller arranged downstream and a second take up side inclined guide are included. Height of a lead formed at a fixed portion of rotary head drum is set such that it becomes lower than the lower end of the magnetic tape for its entire region, at the time of loading and unloading of the magnetic tape. By this structure, contact between the lower end of the magnetic tape and the edge of the lead at the time of loading and unloading of the magnetic tape can be avoided, and therefore damage on the magnetic tape caused by the lead edge can be prevented, and the life of the tape can be made longer.

A machine for making an emulsified product from a mixture of a gas and a liquid milk product capable of forming a foam which comprises a fixed whipping barrel, having a substantially labyrinth passage defined therein, and to which the liquid milk product, after having sucked by and mixed with the gas in a suction pump, is supplied under pressure. The liquid milk product mixed with air is emulsified as it flows through the labyrinth passage in the fixed whipping barrel and then supplied towards a rotary whipping barrel having therein a stirring rod rotatable about its longitudinal axis. The emulsified milk product is, during its passage through the rotary whipping barrel, stirred by the rotary stirring rod so that it can be further emulsified to provide a highly homogenized emulsion which is subsequently discharged from a dispenser.
