The inventive photosensitive resin composition has excellent heat resistance, adhesiveness to substrate surface and photosensitivity and suitable as a material for solder resist or plating resist on printed circuit boards. The resin composition comprises, in addition to a photopolymerization initiator and curing agent for epoxy resins, a resinous ingredient composed of a diallyl phthalate resin, a first esterified resin as a reaction product of a cresol novolac type epoxy resin and 0.2-0.8 mole per mole of epoxy groups of an ethylenically unsaturated carboxylic acid and a second esterified resin as a reaction product of a phenol and/or cresol novolac type epoxy resins and 0.9-1.1 moles per mole of epoxy resins of an ethylenically unsaturated carboxylic acid in a limited proportion.

An object is to reduce a fluctuation in the gas-turbine output in a nozzle switching period. In the nozzle switching period during which a first nozzle group that has been used is switched to a second nozzle group that is going to be used, the amounts of fuel supplied through the first nozzle group and the second nozzle group are adjusted by using at least one adjustment parameter registered in advance, the adjustment parameter registered in advance is updated according to the operating condition of the gas turbine, and the updated adjustment parameter is registered as an adjustment parameter to be used next.

An electromagnetic wave absorber having an excellent electromagnetic wave absorption characteristic in 5 to 6 GHz band. The electromagnetic wave absorber has a matrix and powder filled in the matrix. The particles of the powder have electrical conductivity at least in surface regions thereof and have a particle diameter of 3 to 20 μm as expressed by D50 value. A volumetric ratio (V) in which the powder is filled in the matrix is set such that a standardized value expressed as a value obtained by dividing a complex relative permeability (μ″) of the electromagnetic wave absorber in a frequency band to be absorbed thereby by the volumetric ratio (V) is constant as far as the particle diameter of the powder used, as expressed by the D50 value, is within the range of 3 to 20 μm.

A sensor with built-in circuits can be improved in the stability of the operation or characteristics. A circuit region and a sensor region are covered by a passivation film. The sensor region is partially covered by the passivation film. The sensor region and circuit region are protected by the passivation film, and an effect of the passivation film on the mechanical displacement of a diaphragm portion can be alleviated so that the sensor with built-in circuits may be improved in the stability of the operation or characteristics.

A sensor adjusting circuit for adjusting a digital sensor, whose circuit scale is small and which can maintain high accuracy in a wide adjustment range is provided. A sensor adjusting circuit for adjusting an analog input signal inputted from a sensor and outputting it as another analog output signal in accordance with a physical quantity to be sensed, comprises: a first analog-to-digital converter having an analog integrator (2) for integrating the analog input signal, a comparator (3) for comparing an output of the analog integrator with a predetermined value, and a D/A converter (7) for outputting an output of the comparator as the input signal; and a second digital-to-analog converter (5) for converting the output of the comparator and outputting it as the analog output signal.
摘要:
In a capacitance type pressure sensor, a diaphragm is formed of a fragile material using an impurity-diffused monocrystal silicon and constitutes a stable pressure-responsive structure which does not undergo a plastic deformation. Between the diaphragm and a movable electrode is formed an oxide film to diminish stray capacitance between the movable electrode and a substrate and also between the movable electrode and a impurity-diffused layer. The oxide film and the movable electrode are each divided into plural regions so that the divided regions of the movable electrode are formed on the divided regions of the oxide film, thereby diminishing stress strain induced by a difference in therm expansion coefficient among the diaphragm, oxide film and movable electrode. The upper surface of a fixed electrode is covered with a structure for the fixed electrode which structure is formed by an insulating polycrystal silicon film not doped with impurity whereby the rigidity of the electrode is enhanced and it is possible to diminish a leak current.
摘要:
In CVD processes susceptors can be made of a thermally conductive ceramic such as aluminum nitride which has superior durability with respect to fluorine plasma. Such aluminum nitride susceptors can include an embedded heater element and/or embedded ground or RF electrodes which as a result of their embedment are protected from the deleterious effects of the processing chamber environment. The conductors leading to these elements are protected from exposure to the process chamber environment by passing through a cylindrical member filled with inert gas supporting the wafer support plate of said susceptor. Alternately, the conductors leading to these elements can be run through passages in a hermetically sealed stem supporting the susceptor wafer support plate. The stem passes through the wall of the processing chamber so that connections to the susceptor wafer support plate can be made outside the processing chamber. Such a stem supporting the susceptor support plate can also provide passages for passing vacuum and purge gas to the back of the wafer support plate. Vacuum and purge gas can then be distributed through passages in the wafer support plate as appropriate to its top surface for a vacuum chuck and perimeter purge gas flow.

This invention provides a simple means for detecting a renal disorder, a diagnostic marker for a renal disorder that enables prognostic prediction of a renal disorder (e.g., diabetic nephropathy and IgA nephropathy) and evaluation of the degree of nephropathy at the phase of stage-II diabetic nephropathy by measuring the megalin level in urine associated with a renal disorder used for the detection means, and use of such marker. The invention also provides the use of human megalin obtained from the urine sample of a subject as a marker for detecting a renal disorder.
