摘要:
In an ultrasonic imaging apparatus, an object to be inspected is scanned while being irradiated by a generated ultrasonic beam. Echo signals from the object are received and a plane image and a cross-sectional image formed from the received echo signals are displayed. A marker indicating the focus position of the ultrasonic beam and a marker indicating the setting range of a detection gate are synthesized and displayed on the cross-sectional image. The plane image of the portion assigned by the focus position and the depth range on the cross-sectional image is obtained.

An ultrasonic measuring method and an ultrasonic measuring apparatus utilize the level of a reflected ultrasonic reception signal coming from an object to be examined as measurement data after the level has been provided with either a positive or a negative sign in accordance with the phase of the reception signal.
摘要:
Ultrasonic apparatus that automatically adjusts the focus of ultrasonic waves to a desired depth within an object includes an ultrasonic probe which irradiates a focused ultrasonic beam onto an object to be inspected and a receiver which receives ultrasonic waves reflected from the object. A desired focusing depth is set and the inherent focal length of the probe and the velocity of sound within the object are detected to evaluate a distance between the probe and the object at which the focus of the probe coincides with the desired depth. The distance between the probe and the object is adjusted to coincide with the evaluated distance.
摘要:
An aqueous ink ensuring less blurring and high color formation on plain paper, satisfactory color formation and fixing property on special paper and excellent ejection stability is realized by using a microcapsule of a colorant encapsulated with a polymer and rendered dispersible in water and specifying the amount of the aromatic ring in the polymer to be from 20 to 70 wt % of the polymer.
摘要:
The present invention provides an ink jet printer having storage for storing ink, a recording head including a nozzle for ejecting ink, and a passage between the storage and the recording head for conducting the ink. At least one of these components comprising an ink-contacting member that comprises an antioxidant of the following formula (1) of a concentration of 100 ppm or less: Further, an ink jet recording method using the ink jet printer causes such printer to eject droplets of an ink composition and attach the droplets to a recording medium.

The present invention provides an ink jet printer having an ink-contacting member which is in contact with an ink until the ink is injected from a print head and which contains an antioxidant, wherein the ink-contacting member has a concentration of a compound represented by the following formula (1) of 100 ppm or less: Further, an ink jet recording method using the ink jet printer and recorded matter recorded by the ink jet recording method are also disclosed. According to the invention, there is provided an ink jet printer using an ink-contacting member which inhibits the formation of a crystalline molecular complex.
摘要:
A communications device includes a communications circuit, a memory, an identifier generator, and a latency controller. The communications circuit exchanges serial data with a host computer and a downstream device, and includes a first input, a first output, a second input, and a second output. The first input receives data from the host computer. The first output transmits data to the host computer. The second input receives data from the downstream device. The second output transmits data to the downstream device. The memory is accessible through the communications circuit. The identifier generator generates an identifier number unique to the communications device in response to an identifier setup request received at the first input. The latency controller determines, based on the generated identifier number, a period of latency required to access the memory through the communications circuit.
摘要:
A parallel processor includes a global processor which interprets a program and controls the entirety of the parallel processor. A processor-element block includes a plurality of processor elements each comprising a register file and an operation array for processing a plurality of sets of data. The global processor outputs a control signal to the plurality of processor elements, and, thereby, sets processor-element numbers corresponding to the plurality of processor elements as input values of the operation arrays, respectively.
摘要:
An ink tank cartridge for use in an ink jet recorder has a container having exterior walls, a porous member is stored in the container, an ink supply port that extends through one of the exterior walls of the body to supply ink to the exterior of the cartridge, and a packing member, disposed within the ink supply port and having an opening therethrough and a rib formed on a upper surface. A pressing member may be provided to bias the packing member against an inner surface of the ink supply port. The ink tank cartridge can be assembled to limit the occurrence of air bubbles in the tank.
