Title: Heat treatment
Inventor: MATSUSHITA SHIGEHARU
IPC: H01L21/265
Filed: 1988-10-20
Abstract: PURPOSE:To execute a heat treatment by which an irregularity inside a face of an activation rate is reduced and whose activation rate is excellent by a method wherein, after an SiO2 film and an SiN film have been formed on a III-V compound semiconductor substrate where an ion-implanted layer has been formed, a film thickness of the SiO2 film is specified during a process to heat the ion-implanted layer. CONSTITUTION:An SiO2 film 2 is formed on a III-V compound semiconductor substrate 1 where an ion-implanted layer 4 has been formed; then, an SiN film 3 is formed on the SiO2 film 2; the ion-implanted layer 4 is heated. During this process, the SiO2 film 2 is set to a film thickness at which an external diffusion of a group III element constituting the substrate 1 during a heating process can reach a saturation point. Thereby, the SiN film 3 formed on it can restrain the group III element from being diffused externally; it reduces an irregularity inside a face of an activation rate; a heat treatment whose activation rate is excellent can be executed.

IPC: B60R21/00
Filed: 1991-10-15
Abstract: PURPOSE:To provide a range finder apparatus which does not malfunction even when receiving light from another moving body (e.g. a car). CONSTITUTION:A code generator 3 outputs to an electro-optical modulator 4 a code that specifies the car on which it is placed. The electro-optical modulator 4 modulates the intensity of light at the '0' and '1' of the code and emits the modulated light toward a subject to be measured such as an obstacle to the car via a projection lens 5. A photoelectric convertor 7 converts light that it receives into an electric signal and feeds the signal to a delay correlator 8. The delay correlator 8 correlates the code output by the code generator 3 with a code included in the electric signal that the photoelectric convertor 7 outputs and, when the codes coincide with each other, outputs a measurement effective signal to a measuring controller 1 and when the codes do not coincide outputs a measurement ineffective signal to the measuring controller 1.

Abstract: PURPOSE:To prevent surface irregularity in flatness or cracks of the surface, by interposing an underlying layer containing elements such as nitrogen or the like under a metallic film by which a coil is to be formed, and thermally diffusing these elements in a part of the underlying layer which is unrequired as an electric circuit for providing electrically insulating property to the diffused region. CONSTITUTION:An underlying layer 3 is formed in pattern on a substrate 10, in correspondence with a part that is unneeded as an electric circuit of a thin- film coil to be formed. Then a metallic film 5 for forming the coil is formed on the underlying layer 3. Then the structure is heated at a high temperature under a vacuum, so that a diffused region is formed by diffusing nitrogen atoms from the source of the underlying layer, and the diffused region is extended not only through the thickness of the film but also transversely. Thus, the metallic film 5 is not exposed on the surface in any way and need not be coated with an insulating film. Accordingly, an extremely desirable thin-film coil can be provided without causing surface irregularity in flatness or cracks.

IPC: H04N3/185
Filed: 1988-10-21
Abstract: PURPOSE:To stabilize an anode voltage against the change of an anode current by detecting the variation of the anode current, and adding the variation of the anode current to the output voltage detecting circuit of a constant voltage control circuit as the voltage. CONSTITUTION:An increased quantity  IH of an anode current IH is detected by a current detecting circuit 7, information is sent to a voltage control circuit 8, the voltage control circuit 8 converts it into the voltage, and sends the information added to the output voltage by - VCC to an output voltage detecting circuit 5. The output voltage detecting circuit 5 judges by the information that the output voltage has dropped by  VCC, the information is transferred to a driving circuit 4, and the output voltage is increased by  VCC by increasing the driving current of a control circuit 3. When the output voltage is increased by  VCC, an input voltage VCC of a fly back transformer FBT1 is increased by  VCC. Thus, the stability of an anode voltage VH is attained. In addition, when the anode current IH is decreased by  IH, the same processing is executed, the input voltage VCC of the FBT1 is decreased by  VCC, and the anode voltage HV can be stabilized.
