A series of optical spectral sensors is based on a combination of solid-state sources (illumination) and detectors housed within an integrated package that includes the interfacing optics and acquisition and processing electronics. The focus is on low cost and the fabrication of the sensor is based on techniques that favor mass production. Materials and components are selected to support low-cost, high volume manufacturing of the sensors. Spectral selectivity is provided by the solid-state source(s) thereby eliminating the need for expensive spectral selection components. The spectral response covers the range from the visible (400 nm) to the mid-infrared (25,000 nm/25.0 μm), as defined by the availability of suitable low-cost solid-state source devices. A refractive optical system is employed, primarily in an internal reflection mode, allowing a selection of sample handling tools, including, but not restricted to internal reflectance and transmittance. A secondary channel allowing for light scattering or fluorescence methods is an option. The targeted applications of the sensing devices are for lubricants and functional fluids in the heavy equipment, automotive and transportation industries. A source reference channel is included to provide measurement stability and temperature compensation.

A heat exchanger having excellent heat exchanging performance is obtainable by a simple production technique and at a low cost. This is achieved by providing a fin member and by increasing heat conductivity between the fin member and a meandering pipe body. Further, the heat exchanger is made compact for high degrees of layout freedom, enabling the heat exchanger to be installed in a tight space.

A pair of meandering sections is arranged opposite to each other with an insertion gap of the fin member in between. On of the meandering sections and the other meandering section are connected by a connection pipe to form a meandering pipe main body. The straight pipe sections of the one meandering section are arranged in the engagement grooves in the one end surface of the fin member inserted and arranged in the insertion gap between the one meandering section and the other meandering section of the meandering pipe body, and the straight pipe sections of the other meandering section are arranged and fixed in the engagement grooves in the other end surface.

An inverter device capable of smoothly driving an alternating current synchronous motor of large capacity and high-speed rotation is provided. The inverter device includes a power rectification main circuit for converting alternating current power into direct current power and a PWM control inverse transformation main circuit. A transformer raises output terminal of the alternating current power of the inverse transformation main circuit to drive an alternating current synchronous motor. The alternating current motor is started bypassing the transformer and limiting output voltage of the inverse transformation main circuit to a low value through PWM control of the inverse transformation main circuit. After a predetermined time, the bypass circuit is interrupted and switched to a circuit via the transformer, and the output voltage of the inverse transformation main circuit is raised through PWM control of the inverse transformation main circuit, thus the alternating current synchronous motor is brought into normal operation.

A fine silver particle powder is provided that is a suitable material for interconnects used to form fine circuit patterns especially by the inkjet method, and a method of manufacturing the powder.
