Abstract: There is described a method and sub-circuit to measure temperature coefficients (coefficient of variation of a measurable parameter of the component), by using a thermally-isolated silicon micro-platform with a mass of mono-crystalline silicon suspended from it. The particular effectiveness of the measurement of temperature coefficient(s) stems from the influence of the mono-crystalline silicon mass in maintaining a substantially uniform temperature throughout the micro-platform. The measurement of temperature coefficient can be an absolute temperature coefficient of one or more components, or can be a relative temperature coefficient of two components, or can be relative temperature coefficients between more than two components.

Abstract: A magnetic resonance diagnosis apparatus is capable of performing magnetic tagging of a three-dimensional region to visualize three-dimensional motion or to quantitatively handle the motion. In this apparatus, a control unit controls a gradient magnetic field power source of each axis so that magnetization by gradient magnetic fields generated from a gradient magnetic field coil describes a three-dimensional orbit inside space and performs magnetic tagging for a predetermined three-dimensional region of an object by adjusting a magnitude of gradient magnetic field pulses, pulse intervals and application times. Consequently, one can provide an MRI apparatus capable of more flexibly observing motion of organs and flow of blood.

Abstract: A tandem color laser printer, in which processing units can be smoothly attached to and detached from its casing, is provided while an adequate accuracy of exposure to photosensitive drums is maintained. In the color laser printer, scanning units are fixed to the printer casing. The processing units and the scanning units are alternately aligned and overlapped. A top cover is provided to a side opposite to a transfer position where the photosensitive drums contact a conveyor belt so as to freely open and close with respect to the printer casing. With this structure, the adequate accuracy of exposure by the scanning units can be maintained. The processing units can be attached to and detached from the printer casing via an upper opening of the printer casing defined by the opened top cover. Thus, the processing units can be smoothly attached to and detached from the printer casing without being interfered by the scanning units.

Abstract: In a method for shimming a magnetic resonance imaging scanner (10), at least one of fat suppression and blood suppression is performed to suppress magnetic resonance from a corresponding at least one of fat and blood. First and second magnetic resonance echoes emanating from a generally columnar volume are measured. The measurements of the first and second magnetic resonance echoes (122, 124) are reconstructed (150) into corresponding first and second generally columnar projection images (152, 154). The first and second generally columnar projection images are combined (160) to produce a magnetic field profile (174) of the generally columnar volume. Selected magnetic field parameters are extracted (142) from the magnetic field profile. Shim currents are computed (180) from the selected magnetic field parameters. The shim currents are applied to magnetic field coils (16, 60).

Abstract: A chalk line apparatus for marking regularly spaced locations. The apparatus comprises a casing for powdered chalk containing a rotatable reel, a wire rope wound on said reel, and an exit opening for the wire rope at one end of the holder.

When the line is snapped, the chalk-covered short segments leave evenly spaced chalk marks that correspond to the locations of underlying wall studs.

Abstract: An impact-absorbing end cap for an instrument such as a level is provided that is secured to an end of the level and has an outer portion and an intermediate portion. The intermediate portion is positioned between the outer portion and the body of the level and is securely fastened to the outer portion. In addition, the intermediate portion provides greater resilient compressibility than the outer portion so that the end cap is better adapted to absorb impacts to the outer portion and thereby prevent damage to the level. Preferably, the outer portion has a profile matching the body profile at the end of the level and the intermediate portion forms a serrated intermediate profile to facilitate compression of the end cap. Also preferred is where the end cap includes an inner portion with less resilient compressibility than the intermediate portion.

Abstract: The invention enables to monitor a magnetic field drift of a magnetic resonance imaging apparatus on the basis of the magnetic resonance signals, which are acquired during magnetic resonance image data acquisition, such as by single shot EPI or by a gradient echo sequence. The phases of at least two magnetic resonance signals are acquired an echo time after the corresponding RF excitations. This corresponds to the central k-space line, which has frequency encoding but no phase encoding. The difference of two consecutive phase measurements, which are acquired at a certain time interval provides the shift of the resonance frequency. This enables monitoring of the shift of the resonance frequency and compensation of the magnetic field drift.
