Title: Semiconductor laser and method for manufacturing the same
Inventor: MIYAKE TERUAKI
IPC: H01S5/343
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To provide the semiconductor laser of high output and an aspect ratio close to 1. SOLUTION: Semicondcutor layers are laminated in an order from an n-type clad layer 110 to an etching stop layer 140 on an n-type semiconductor substrate 100 and a p-type second clad layer 150, a p-type contact layer 160 and a p-type cap layer 170 formed on the etching stop layer 140 are turned to a ridge structure. Also, on a ridge side face, a p-type GaInP layer 180, an n-type GaAs layer 190 and the n-type GaInP layer 200 are laminated in the order so as to be parallel to the side face. Further, since the n-type GaAs layer 190 near a ridge top is eliminated, a current can be injected from not only the top of the p-type cap layer 170 but also the ridge side face.

Title: Plasma cvd system and method for forming non-single crystal semiconductor thin film
Inventor: KODA YUZO
IPC: H01L21/205
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To obtain a plasma CVD system and a method for forming a non- single crystal semiconductor thin film in which a high quality semiconductor thin film can be formed at a high deposition rate while suppressing defects. SOLUTION: At least one surface of a hydrogen adsorption alloy 46 is exposed in a plasma discharge space or at a position contiguous thereto. The hydrogen adsorption alloy 46 is cooled to a specified temperature, as required, using a water cooling mechanism 47, e.g. a water cooling jacket. According to the arrangement, a species containing no group 4A atom generated through plasma discharge decomposition is removed from a gas composed of a compound containing group 4A atoms and hydrogen atoms in a plasma discharge atmosphere thus lowering partial pressure of the species containing no group 4A atom. Consequently, a high quality photovoltaic element having excellent uniformity and reduced defects can be produced by forming a semiconductor thin film while satisfying contradictory purposes of high deposition rate and high film quality at high level.

Title: Electronic component feeder
Inventor: TAKAHASHI TAKAYUKI
IPC: H05K13/02
Filed: 2000-03-28
Abstract: PROBLEM TO BE SOLVED: To provide an electronic component feeder which can adapt to the thickness difference of containing tapes without troublesome adjusting works, and stably feed components only by loading the containing tape without floating tape guides. SOLUTION: A turn plate 22 is turnably mounted on a turn plate 21 and pressed in a direction R2. When a component feeder 20 is mounted on a mount 19, the top end of the turn plate 22 contacts the mount top so as to turn the turn plate 22 in a direction R1. The pressure in a direction R2 toward the turn plate 22 is exerted to turn the turn plate 21 in a direction Q1. As the result, a boss 21c of the plate 21 contacts a guide 15 from below to exert an adequate pressure on the guide 15 in a direction M2, thus narrowing the swing range of the guide in a direction M1 to suppress the guide 15 from floating up.

Title: Coordinate reader
Inventor: OHASHI TSUTOMU
IPC: G06F3/03
Filed: 2000-03-30
Abstract: PROBLEM TO BE SOLVED: To realize a coordinate reader capable of reducing noise to be generated at both ends of a loop-like pattern. SOLUTION: Patterns 23Xa, 23Xb are printed by pattern in so-called a twist pair electric wire in which the patterns are crossed by every prescribed interval. In addition, a resist layer R is interposed between the patterns 23Xa and 23Xb at each crossed part and both patterns are insulated at the crossed part. Thus, even when a line of magnetic force to be orthogonally crossed with both patterns exists, since electromotive force generated at the crossed part by the line of magnetic force supplies power in the direction to mutually compensate the electromotive force for both patterns, the electromotive force is mutually compensated. Consequently, the noise to be generated at both ends of the loop- like pattern is reduced.
