Patent JP-S6257255-A (JP)
Title: Manufacture of compound semiconductor device
Inventor: IMAMURA YOSHINORI
IPC: H01L29/80
Filed: 1985-09-06
Abstract: PURPOSE:To prevent deterioration in characteristics due to stress, by using protecting films, wherein a film that imparts tensile stress to a GaAs semiconductor substrate and a film that imparts compression stress to the substrate are laminated, as the surface protecting films of the GaAs substrate at the time of annealing, thereby reducing the effective stress of the GaAs substrate. CONSTITUTION:Ions are implanted in the surface of a compound semiconductor 1. An insulating film 12 imparts tensle stress to the semiconductor substrate 1. An insulating film 13 or a conducting film imparts compression stress to the semiconductor substrate 1. Protecting films are formed by a laminated structure of the film 12 and the film 13. After the formation of the protecting film 12 and 13, heat treatment is performed. Thereafter parts, where electrodes 6 and 7 are to be formed at the surface of the semiconductor substrate 1 corresponding to said protecting films 12 and 13, are removed. For example, an N-channel 2 is formed by activation using an Si<+> ion implantation method and annealing in the surface in the GaAs substrate 1. Then, a WSi gate 5 is formed. Therefore, a part other than source and drain gates is covered with photoresist 10. The source and drain regions are formed by the ion implantation method in a self-aligning mode. Then the SiO2 film 12 is deposited by a sputtering method. The SiO2 film 13 is deposited by a chemical vapor deposition method at a normal pressure.

IPC: G03B13/36
Filed: 1989-07-27
Abstract: PURPOSE:To solve the failure of range-finding parallax by arranging the passive autofocusing system of pupil deviding method in an outside finder system. CONSTITUTION:The picture signals of line sensors 19a and 19b are operated by a control circuit 20, and a focusing lens 1 is driven by a driving device 21, whereby focal adjustment is carried out. As for the focal adjustment of the finder system, a first lens 8 is mechanically interlocked with the lens 1. Focal state is confirmed by secondary picture-forming lens 18a and 18b, the sensors 19a and 19b, and the circuit 20. When the object is out of focus, the lenses 1 and 8 are driven by the device 21 and stopped when the object is con firmed to be in the focus. Since the objective lens system of the finder system is thus shared with a range-finding system, a focal point can be detected without range-finding parallax by exactly detecting the focal point of the object of a range-finding mark in the visual field of the finder regardless of zooming and photographing distance.

Title: Formation of powder film on inner surface of tubular bulb
Inventor: OTANI KATSUYA
IPC: H01J9/20
Filed: 1984-09-19
Abstract: PURPOSE:To achieve a simple method of forming a film of a phosphor or similar material which has increased adhesive strength using only a small amount of powdery mixture by mixing a powdery original material with several percents by weight of a coating agent to prepare the powdery mixture which is applied by an electrostatic application device and then sintering the applied mixture. CONSTITUTION:After 0.1-5wt% of a coating agent composed of low-melting glass is mixed into a powdery material, the thus prepared powdery mixture is applied to the inner surface of an outer tube by a dielectric application device and then sintering is performed to fix the applied mixture to the inner surface. During the above process, only a minimal loss of the powder is caused during its dielectric application to the inner surface of the outer tube. Furthermore, during the following process of sintering, the coating agent in the powder melts to cause the powder particles and the outer tube glass bulb surface to stick together, thereby achieving suitable adhesive strength. Additionally, since it is not necessary to use a binder such as lacquer in addition to the coating agent in the powder, there is nopossibility that any deterioration of the luminous flux occurs as the time of lighting increases.
