An accelerometer or a seismometer using an in-plane suspension geometry having a suspension plate and at least one fixed capacitive plate. The suspension plate is formed from a single piece and includes an external frame, a pair of flexural elements, and an integrated proof mass between the flexures. The flexural elements allow the proof mass to move in the sensitive direction in the plane of suspension while restricting movement in all off-axis directions. Off-axis motion of the proof mass is minimized by the use of intermediate frames disbursed within and between the flexural elements. Intermediate frames can include motion stops to prevent further relative motion during overload conditions. The device can also include a dampening structure, such as a spring or gas structure that includes a trapezoidal piston and corresponding cylinder, to provide damping during non-powered states. The capacitive plate is made of insulating material. A new method of soldering the capacitive plate to the suspension plate is also disclosed.

A power source apparatus includes a power source module which is formed of a plurality of power source elements, a case which houses the power source module and a cooling liquid, a fan which is placed in the case in a state in which the fan is immersed in the cooling liquid together with the power source module, the fan forming a laminar flow of the cooling liquid, the laminar flow having a width at least substantially the same as a length of the power source element in a length direction of the power source element.

The invention discloses an energy-saving type shuttle type kiln. The energy-saving type shuttle type kiln comprises a furnace body, at least one pair of heat-accumulating type combustors, a heat exchanger, corresponding valves, pipelines and a fan, wherein the combustors are arranged on the furnace body and are connected with the fan and a gas pipeline by the pipelines and the valves. When one of the combustors is in a combusting state, the other one is in a smoke-exhausting state, and the smoke stores heat in a heat-accumulating material in the combustors, and then is exhausted out of the system. When the preset time is up, the valves of the two combustors are switched, the combustor in the smoke-exhausting state is changed to be in the combusting state, and air absorbs the heat stored in the heat-accumulating material when passing through the combustor and carries the heat into a furnace so as to realize heat recovery. When a plurality of pairs of combustors are arranged, the working state of each combustor is opposite to that of the peripheral combustors so as to realize cross combustion. In the cooling process, heating and water supply are performed on the hot air by the heat exchanger on a spare flue, and the heat is absorbed by water so as to be utilized. The energy-saving type shuttle type kiln has the advantages that not only is the energy-saving effect obvious, but also the temperature distribution in the hearth is uniform, the temperature rising speed is high and the combustion temperature is high.
