An apparatus, for forming a film, includes an ink jet head having a plurality of nozzles for discharging a liquid, a rotating device for rotating about a rotary axis a coating-object substrate onto which liquid discharged from the ink jet head is deposited, a relatively moving device for moving the ink jet head and the coating-object substrate relatively to each other between a nearby region of the coating-object substrate near the rotary axis and a separate region of the coating-object substrate separate from the rotary axis, and a relative movement control device for controlling the relatively moving device so that an angular velocity of rotation by the rotating device is reduced responsively as a relative position of the ink jet head and the coating-object substrate therebetween makes relative movement from the nearby region toward the separate region, and an angular velocity of rotation by the rotating device is reduced responsively as the relative position of the ink jet head and the coating-object substrate therebetween moves relatively from the nearby region toward the separate region.

An information transmission method capable of reproducing the atmosphere of a concert hall or a live performance hall, wherein bio-information of a speaker, player, actor or conductor, who serves as a source of speech, sounds or music and/or bio-information of a performer included within an image are multiplexed with respect to information of speech or music and/or information of the image for transmission thereof. At the receiving side, sense stimulation based on the bio-information is provided to the viewer, or information of speech or music and/or information of the image are controlled on the basis of the bio-information to thereby reproduce presence or live appeal.

A sound producing apparatus includes a sound data reproduction unit that reproduces sound data, a meta-data analyzer that analyzes meta-data indicating the properties of the sound data, a room acoustic characteristic analyzer that measures an acoustic characteristic of a listening room, and a reproduction characteristic adjuster. The reproduction characteristic adjuster performs an acoustic characteristic adjustment on the sound data to be reproduced based on the room acoustic characteristic data obtained by the room acoustic characteristic analyzer and the acoustic characteristic data obtained by the meta-data analyzer.

A sound field reproduction apparatus generates sound field synthesizing parameters according to a relative positional relationship between the listener and the sound source and performs frequency conversion on sound data according to the relative positional relationship. A convolutional operation is conducted on the sound data that are subjected to the frequency conversion and the generated sound field synthesizing parameters in order to synthesize the sound of the sound source of each channel. The synthesized sound is subjected to wave front synthesis for the synthesized sound by using n-channel sound sources to reproduce a sound field in a predetermined area.

A hearing aid is disclosed in which the outside sound collected by a microphone is amplified and radiated from the earphone unit so as to be conducted to the user's external auditory meatus. The auditory tube is of an inside diameter approximately equal to that of the user's external auditory meatus and has one end arranged as a section for attachment to the user's auricle and the other end arranged as a reflectionless terminal. The earphone unit is mounted on the peripheral surface of the auditory tube with the sound radiating surface facing the inside of the tube.

In an ink jet printer, a print head comprises a front nozzle member having a front channel, a housing secured to the front nozzle member, and a rear nozzle member which defines with the housing a liquid chamber and further defines with the front nozzle member a laminar airflow chamber. The rear nozzle member has a forwardly projecting nozzle and a rear channel extending from the liquid chamber through the projecting nozzle in axial alignment with the front channel to form a meniscus at the front end. The airflow chamber is connected to an air supply for directing air to a point between the front and rear channels so that it creates a sharp pressure gradient along a path therebetween. A dead air region is created in a location adjacent the exit end of the rear channel to cause the meniscus to take a dome-like shape which is stabilized against vibrations and transients. An electric field gradient is established between the front channel and the meniscus to cause the latter to extend toward the front channel and expelled through the front channel. A portion of the front nozzle member is rendered liquid-repellant to prevent the field distribution from being seriously disturbed by an ink layer formed on it by stray liquid particles.

Disclosed is a method for operation of an ink jet printing head of the type wherein printing ink is discharged from a plurality of ink nozzles toward a writing surface by the aid of an electric field established between a plurality of control electrodes associated with the ink nozzles and a common electrode in opposed relation to the control electrodes. In response to a picture element signal for controlling the discharge of ink from the ink nozzles, a control pulse is generated and applied to each of the control electrodes, while a pulse bias is generated and provided to the common electrode. The pulse bias is supplied thereto only in the presence of the control pulse. The minimum width of the control pulse is established to be greater than 1/fp and smaller than 2/fp where fp is the frequency of the picture element signal.
摘要:
In a nonimpact printer having a reciprocable printer head, ink is supplied to the head through a pair of identical, flexible conduits which are connected from first and second spaced apart outlets of an ink container. The container is not air tight with the outside so that it can act as a pressure absorber. Each of the first and second conduits have a sufficient length to allow the head to reciprocate along the length of a platen with end of each conduit moving therewith to cause pressure variations to occur in the conduits when the printer head varies its speed of movement. By virtue of the pressure absorbing action of the liquid container, the pressure variations are nullified and the printer head is supplied with constant pressure ink.
