Abstract:
A content reproduction system uses a first reproducer and a second reproducer to respectively reproduce corresponding first content information and second content information, which are to be played back at a synchronized timing. A first delay amount specification module of the first reproducer obtains a first base delay amount corresponding to a reproduction timing of the first content information and a first additional delay amount set in a first delay processor of the first reproducer. The first delay amount specification module also receives a second base delay amount corresponding to a reproduction timing of the second content information and a second additional delay amount set in a second delay processor of the second reproducer, which are notified by a second delay amount specification module of the second reproducer. The first delay amount specification module updates the first additional delay amount and the second additional delay amount to make a second reproduction delay amount specified according to the second base delay amount and the second additional delay amount consistent with a first reproduction delay amount specified according to the first base delay amount and the first additional delay amount. The first delay amount specification module sets the updated first additional delay amount in the first delay processor, while giving an instruction to the second delay amount specification module to set the updated second additional delay amount in the second delay processor. This arrangement desirably reduces a potential time difference between a reproduction timing of the first content information by the first reproducer and a reproduction timing of the second content information by the second reproducer.
Abstract:
A sample is sliced obliquely with a blade provided with a metal thin film on the surface, and the slice of the sample adhering to the blade surface is subjected to mass spectrometry. As a result, the section of the sliced sample can be analyzed immediately by mass spectrometry with high sensitivity.
Abstract:
A probe needle 20 includes a cantilever 21, a column 22 and a tip 23. The column 22 is cantilevered from an end of the cantilever 21. The tip 23 is formed on a top end of the column 22. The column 22 is formed so as to be longer than the tip 23. The heights of the column 22 and tip 23 are chosen so that their sum is twice or more than twice the width of the columnar 22.

Abstract:
An active noise control system is capable of canceling out noise in the passenger compartment of a vehicle based on low-frequency road noise. The active noise control system has a feed-forward control unit for being supplied with reference signals highly correlated to noise from a noise source and generating a noise cancellation signal which is out of phase to noise in the passenger compartment of the vehicle, and a canceling sound generating unit disposed in the passenger compartment for generating a noise canceling sound in response to the noise cancellation signal from said feed-forward control unit. The active noise control system also has microphones for generating reference signals which are positioned respectively near the base of the front seat, near the center of a roof, and within a trunk compartment, i.e., respectively at vibrational antinodes of a primary or secondary acoustic normal mode of the passenger compartment in the longitudinal direction thereof. Output signals from the microphones are supplied as the reference signals.
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.

An electron-emitting device having favorable electron emitting characteristic stable for a long time, which is manufactured by a method comprising the steps of disposing an electrically conductive member having a second gap on a substrate, and applying a voltage to the electrically conductive member while irradiating at least the second gap with an electron beam from electron emitting means disposed apart from the electrically conductive member in an atmosphere comprising a carbon compound.
Abstract:
In-plane distribution of a target objectcontained in a sample is measured. The sample dispersedly placed on a substrate is treated to promote ionization of the target object, then the mass and flying amount of an ion containing the target object or a component of the target object is determined by irradiating an ion beam to the sample and performing time-of-flight secondary ion mass spectrometry of the ion that flies from a portion in the sample where the ion beam is irradiated, and the in-plane distribution of the target object is determined from the mass and flying amount data obtained at plural portions by scanning the beam on the sample plane. The step of treating the sample to promote ionization of the target object includes contacting an aqueous solution of an acid that does not crystallize at ordinary temperature with the sample. A high spatial resolution two-dimensional image can be obtained.
