A method for processing a waste solution used in a chemical plating process and including a heavy metal complex salt, a reducing agent, and a pH adjusting agent. The heavy metal complex salt is decomposed into a heavy metal component and a complexing agent component by applying ultrasonic vibration to the waste solution. The heavy metal component obtained by decomposition is in a powder state. Then the waste solution is filtered, so that the heavy metal component may be separated from the complexing agent component.

A method of forming a vibrating gyroscope includes the steps of providing a vibrating body and disposing at least one driving member on the vibrating body so that the at least one driving member is arranged to generate vibration in the vibrating body in a vibrating direction that is substantially perpendicular to an axis of the vibrating body. Then, at least two detection members are disposed on the vibrating body such that the at least two detection members are spaced from each other, located on opposite sides of a plane including the axis and the vibrating direction of the vibrating body, arranged to detect a rotational angular velocity applied to the vibrating body and arranged in a non-parallel relationship relative to each other and in a non-parallel relationship relative to the at least one driving member.

A platinum temperature sensor includes a meandering pattern portion and outlet portions continuously connected to respective ends thereof which are defined by a platinum film which is formed on an insulating substrate. External electrodes are formed to cover the outlet portions as well as the ends of the insulating substrate provided with the outlet portions. Each of the external electrodes comprises a first layer containing platinum or nickel which is in contact with the outlet portion and with the insulating substrate, a second layer containing silver and platinum which is formed on the first layer, a third layer containing nickel which is formed on the second layer, and a fourth layer containing tin or solder which is formed on the third layer. The first layer suppresses diffusion of silver contained in the second layer, and the third layer improves heat resistance of the second layer, while the fourth layer improves solderability.

A process for metallizing a copper film comprising the step of heat treating a copper film formed by an electroless plating process as opposing electrodes of a ceramic capacitor. The process comprises the steps of placing a ceramic body having a copper film formed on the surface thereof by an electroless plating process within a container sealing the same from the external atmosphere and maintaining constant the internal atmosphere, and heating the container maintaining the surrounding of the container in an inert atmosphere.

摘要:
The vibrator includes for example, a triangular prism shaped vibrating body. On each of three side faces of the vibrating body, piezoelectric elements are formed respectively. The vibrating body makes bending vibration by giving a driving signal to one or two piezoelectric elements. The vibrator is used in a vibratory gyroscope. In this case, for example, one piezoelectric element is used for vibrating the vibrator. When a rotating force is applied to the vibratory gyroscope, a Coriolis force is exerted to produce output voltages on the remaining two piezoelectric elements corresponding to the rotational angular velocity.

A carbon resistive paste comprising an electrically conductive component, such as carbon; an inorganic filler, such as silica; a resin component, such as an epoxy resin; a solvent, such as ethanol and; if necessary, an organic filler, wherein the inorganic filler is treated with a silane coupling agent, such as .gamma.-glycidoxypropyltrimethoxy silane. The carbon resistive paste provides a resistive film which has limited changes in resistance value in use and is superior in strength.
