Title: Photodetector
Inventor: TAKAHASHI TAKESHI
IPC: H01L31/10
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To improve a photodetector in reliability and high-speed responsibility. SOLUTION: A reverse bias voltage of 3 to 5V is applied to a photodetector, and when light of a wavelength of 830 to 860nm emitted film an LED is made incident on the photodetector, it is absorbed in a p<-> -type GaAs layer 4 penetrating through a P-type Al0.2 Ga0.8 As layer 5 to excite electrons and holes. Electrons out of these carriers are moved to an N-type Al0.2 Ga0.8 As layer 3 in a short time by an inner electric field inside the depleted P<-> -type GaAs layer 4, and holes are moved to the P-type Al0.2 Ga0.8 As layer 5 in a short time. At this point, when an external load is connected to the photodetector through the intermediary of a surface electrode 8 and a black electrode 8, a photocurrent can be extracted.  Holes also generated as photo-excited carriers in an N-type GaAs buffer layer 2 and an N-type GaAs substrate 1 are prevented from being diffused into the P<-> -type GaAs layer 4 by a hetero-barrier of an interface between an N-type GaAs buffer layer 2 and the N-type Al0.2 Ga0.8 As layer 3 and recombined in the layer 2 and the substrate 1.

Abstract: PURPOSE:To improve the focusing efficiency by providing limit switches, which can be turned on/off with a lens, in both ends of the moving range of the lens. CONSTITUTION:An operating element 1a is attached to the upper end part of a lens 1, and a pair of limit switches 11a and 11b are arranged apart from the lens 1 in both ends of a moving area A in the direction of an arrow (a) corresponding to the moving range in the direction of an arrow (b) of the lens 1.

A carbon layer 6 and a cathode current collecting layer 7 employing a conductive paste added to by a silane coupling agent are formed on the surface thereof. Water in the air is absorbed by the humidity absorbing semiconductive metal oxide film 3 reaching the dielectric anode oxide film 2 to measure. The use of the conductive paste added to by a silane coupling agent for the anode current collecting layer 7 can prevent the secular deterioration in the performance of the dielement. Thus, a humidity detecting element having a long, stable humidity characteristics can be obtained.

Title: Welding method by high output high density electron beam
Inventor: OKAMURA HISANOBU
IPC: B23K26/21
Filed: 1978-01-30
Abstract: PURPOSE:To obtain sufficient weld-joint characteristics, when T-type or L-type joint is welded using a high output high density beam, by repairing weld defects generated after the welding work at the weld zone on the side of incidence of the beam and on the opposite side. CONSTITUTION:A T-type joint is made of parts 4 and 5 by the electron beam 6 welding, and the weld zone 7 is formed. Hereupon, a part of molten metal spouts out opposite against the direction of incidence of the beam, and forms the molten metal drop 9; as a result, an undercut zone is formed at the corner on the incidence side depending on the lack of molten metal. In case of circumstances, a lack of penetration is caused. For the purpose of efficiently repairing above stated defects at the weld zone and of forming good reinforcement weld, an additional welding is carried out on the corner of above stated weld zone 7 depending on the unfocused electron beam; hereby, the reinforcement weld 11 is formed. Moreover, the filler metal 10 is preferable to be used for the corner where the undercut is caused. For the L-type joint, the welding is performed similarly to above case.
