A base layer is formed on the surface of metal plate, metal pipe, unbaked ceramic sheet, laminated ceramic green sheet, etc., the base layer causing a gelling reaction with inkjet-ink. The base layer improves ink acceptability for low viscosity inks such as inkjet-ink, and prevents oozing, draining, uneven thickness of an ink pattern and a resist pattern. Thus, the present invention enables to use an ink jet process for providing resist patterns for etching, etc., which has to fulfill stringent high precision requirements.

The invention presents a strain sensor includes a substrate, a crystallized glass laminated on the substrate, a strain sensitive resistor laminated on the crystallized glass, in which the crystallized glass is formed by baking a plurality of types of crystallized glass powder having different thermomechanical constants. As a result, the fluctuation of sensor characteristic is decreased, and the cost is lowered.

Strain sensor and method for manufacture thereof

A load sensor includes a substrate, a glass layer provided on the substrate, a wiring provided on the glass layer, an adjusting layer provided on the glass layer, and a strain-sensitive resistor element provided on the adjusting layer and connected to the wiring. A thermal expansion coefficient of the adjusting layer is closer to that of the strain-sensitive resistor element than that of the glass layer. In this load sensor, a stress remaining inside the resistor element is reduced, and the change over time of the resistance of the element is accordingly suppressed. Therefore, a single kind of the resistor element can be formed on substrates having respective thermal expansion coefficients, shapes, and thicknesses, thereby providing various load sensors having respective specifications.

Load sensor and its manufacturing method

A strain sensor comprising a metal substrate, a first electrode provided on the metal substrate, a glass layer formed on the first electrode, and a second electrode and a strain detecting resistor provided on the glass layer. In the strain sensor, the insulation resistance between the metal substrate and the second electrode has been raised, and the reliability is high. It can be implemented at low cost.

Method of manufacturing strain sensor

The present invention relates to a load sensor and provides a highly accurate load sensor with multi-layered wiring at low costs. It provides crystallized glass and non-crystalline glass which are best for a load sensor, and combines these to form multi-layered wiring, and further, makes a glass layer of composite type as needed, and reduces uneven printing in printing multiple layers with use of hardening type paste.

Here disclosed is an ink jet apparatus having an ink-circulating/dispersing function. The apparatus provides ink with dispersion as required, and circulates the ink through a tube to an ink-collecting tank. During this circulation, a required amount of the ink is fed to a printer head to form a predetermined pattern on a surface of a substrate. By virtue of the circulating/dispersing function, the apparatus can cope well with easy-to-aggregate ink having poor stability in terms of printing, thereby protecting a printer head or an ink-spouting section from clogging during ink jet printing. Such stabilized ink jet printing contributes to manufacturing highly reliable electronic components with an increased yield of products.

The strain sensor allows the layers to be identified while being manufactured, hence being controlled easily in its manufacturing processes.

Method of forming an electronic component using ink

A base layer, which is supposed to be burnt off by baking, is formed on an unbaked member such as ceramic green sheet or laminated ceramic green sheets. This base layer improves ink acceptability of the unbaked ceramic member particularly for low viscosity ink such as jet-ink, and prevents oozing, draining, uneven thickness. This structure thus allows the inkjet to form a precise pattern. The base layer is burnt off at the baking step in the manufacturing process of electronic components, thus it does not adversely affect the reliability of the electronic component.
