Abstract:
A mass spectrometry method that makes it possible to perform high-sensitivity detection of a desorbed/ionized object substance to be measured in mass spectrometry in which the object substance to be measured is desorbed and ionized. The method includes placing at least an ionizing agent having two or more functional groups represented by Formula (1) below in a molecule: —(CF2)COOH (1) wherein the ionizing agent has a boiling point of equal to or higher than 150° C. and an object molecule to be measured on a substrate and irradiating the ionizing agent and the object molecule to be measured with a primary beam selected from ions, neutral particles, electrons, and a laser beam.
Abstract:
To provide a DNA micro-array having a nucleic acid probe immobilized on a substrate, which is used to detect a molecule of a target nucleic acid contained in a sample and has a substantially complementary base sequence to the target base sequence of the nucleic acid molecule, including at least one probe selected from the group consisting of: at least one internal standard probe for assay of PCR of the target nucleic acid; at least one external standard probe for a detection operation and assay of an amount of the probe; and a probe for measurement of the amount or density of the nucleic acid probe, formed by the same method as the nucleic acid probe.
Abstract:
In an acceleration sensor detecting inclined displacement of a predetermined article from a basic position, the acceleration sensor (10) includes a sensor chip having a detection plane including one detection axis or two crossing detection axes detecting the inclined displacement. An axis orthogonal to the detection plane of the sensor chip is disposed in parallel with a standard plane of the article in the basic position. Then, the sensor chip obtains an output signal according to the inclined displacement of the standard plane.
Abstract:
A computer connectable image display apparatus for presentation is provided. The image display apparatus has a candidate information obtaining unit, a selection screen display unit, a presentation execution instruction unit, and a drawing screen display unit. The candidate information obtaining unit obtains selection candidate information generated by the computer relating selection candidates for a presentation subject file. The selection screen display unit generates and displays a selection screen for selecting the presentation subject file based on the selection candidate information. The presentation execution instruction unit makes the computer to execute the selected presentation subject file by sending selection results with the selection screen. The drawing screen display unit captures and displays a computer drawing screen drawn by the computer. The image display apparatus displays the selection screen without displaying the computer drawing screen when a connection with the computer is established, and displays the computer drawing screen when drawing by the computer executing the selected presentation subject file is started.
Abstract:
A sound image control system which is able to concurrently perform sound image localization control for two persons is provided. The sound image control system controls a sound image localization position by reproducing an audio signal from a plurality of loudspeakers. The sound image control system includes at least four loudspeakers for reproducing the audio signal and a signal processing section. The signal processing section sets four points corresponding to both ears of two listeners as control points, and performs signal processing for the audio signal input into the plurality of loudspeakers so that two target sound source positions indicating sound image localization positions of the respective two listeners are set in the same direction with respect to the two listeners. The two target sound source positions are set so as to satisfy the following condition, T1=T2≦T3
Abstract:
A first rectifying net, a rectifying grid and a second rectifying net are attached, as a rectifying part upstream of a duct through which air for cooling flows. A noise detection microphone detects noise within the duct. An error detection microphone is placed in the downstream side of the noise to detect error noise. An arithmetic circuit inputs a noise signal of the noise detection microphone, carries out an arithmetic of a transfer function so that an output signal of the error detection microphone becomes minimum, and outputs a control signal to a control sound source. The control sound source radiates a control sound having approximately the same sound pressure as and an opposite phase of the noise within the duct. Thus, the coherence between the noise in the upstream and downstream parts increases, thereby enhancing a sound-muffling effect.
Abstract:
A method for analyzing an object by means of TOF-SIMS is adapted to apply an ionization promoter (metal such as silver or gold) to the object and generate secondary ions that correspond to parent molecules and can be used to determine the type of the object. A segregation/refinement technique such as electrophoresis or thin-layer chromatography can be employed for a mixed protein sample by using the method to obtain a two-dimensional image showing a high spatial resolution.
Abstract:
To provide a technology for obtaining a probe carrier which is quality assured by an effective inspection program and an effective producing steps. Quality of a produced probe carrier is ensured by expanding test items in the processes from synthesis and purification of the probe to fixation thereof to a carrier.
Abstract:
A headphone system includes a headphone; and a signal processing circuit for outputting an acoustic signal to the headphone. The headphone includes a first speaker and a third speaker for a right ear of a listener, a second speaker and a fourth speaker for a left ear of the listener, and a support for supporting the first through fourth speakers so that the first and second speakers are located forward with respect to a vertical plane including a straight line connecting the hole of the right ear and the hole of the left ear of the listener, the second and fourth speakers are located rearward with respect to the vertical plane, and the first through fourth speakers are out of contact with the right ear and the left ear of the listener.
