Filed: 1994-05-24
Abstract: PURPOSE:To manufacture ceramic electronic components of the uniform and excellent performance even if the burning is conducted in a great quantitity at one time by avoiding the appearance of internal structural defects and the decline in electric characteristics such as a change with the passage of time, in a method for manufacturing a multilayer ceramic capacitor, etc., by sintering Pd or a Pd allay and ceramic into a body. CONSTITUTION:In a temperature range wherein Pd is oxidized in the air, the burning is conducted in an atmosphere wherein Pd is not oxidized. In temperatures above the one wherein Pd is oxidized in the air, atmospheric gas is converted into the air in temperatures above the one wherein PdO is discomposed into Pd in the air and then the atmospheric gas is converted into an oxygen atmosphere in a ceramic shrinkage temperature range. Or otherwise, in temperatures above the one wherein PdO is discomposed into Pd in an oxygen atmosphere, the atmospheric gas is converted into an oxygen atmosphere directly from the atmosphere wherein Pd is not oxidized. Then, the temperature is increased in the oxygen atmosphere and ceramic is sintered in such a circumstance. For the atmosphere wherein Pd is not oxidized, gas including carbon dioxide is used. When converting the atmospheric gas into the oxygen atmosphere, the pressure of the atmospheric gas is reduced first and then is converted into the oxygen atmosphere.

Filed: 1983-07-25
Abstract: PURPOSE:To avoid erasing by mistake the important information on a rewritable optical disk by detecting the information showing the propriety for erasion on the optical disk and controlling the erasing action of a head in accordance with the result of said detection. CONSTITUTION:The detection signal is delivered from a detector 4 for a reference position mark 11 on an optical disk 1 and supplied to a detection circuit 6 and a control circuit 5. The circuit 5 turns on an analog switch 12 in response to the erasion enable signal given from the circuit 6 when the detection signal of an erasion enable mark 12 is detected by the detector 4 after a prescribed period of time. As a result, the erasion signal is supplied to a driver 11 from the circuit 5 to perform erasion. While no erasion enable signal is supplied from the circuit 6 when the detection signal of the mark 12 is not delivered. Therefore the circuit 5 turns off the switch 12 to cut off the supply of erasion signal to the driver 11. Thus it is possible to avoid erasing by mistake the important information.
