Title: Buried-structure semiconductor laser
Inventor: SUGIMOTO MITSUNORI
IPC: H01S5/00
Filed: 1984-10-05
Abstract: PURPOSE:To obtain a laser having low threshold currents with high yield by forming a first clad layer and severally striped first guide layer, active layer and second guide layer in succession and shaping a second clad layer extending over the upper section and both sides of the striped three layers. CONSTITUTION:An N type clad layer is formed onto an N-CaAs substrate 1, a first guide layer 3, an active layer 4 and a second guide layer 5 are shaped onto the clad layer to a striped shape to form a mesa stripe 11, and the mesa stripe 11 is buried to a P type clad layer 6. A cap layer 7, an SiO2 film 8 and a P electrode 9 are shaped onto the P type clad layer 6, and an N electrode 10 is formed onto the substrate 1 as the reverse surface of the electrode 9. The area of a mesa side-surface is small because the height of the mesa stripe 11 is low as approximately 0.2mum in such a laser. Accordingly, trouble of which a crystal material is broken is eliminated because a region as a shadow by a mesa is small on buried growth, and a crystal can also be grown excellently on the side surface of the mesa, thus obtaining the laser oscillating at low threshold currents with high yield.

Title: Initializing device of shift controller for continuously variable transmission
Inventor: KOGA MASAHITO
IPC: F16H59/42
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent impartment of a sense of incompatibility to a driver by performing initializing operation of a motor by erroneously detecting stopping at traveling time by providing a means for initializing a command value to the motor as a reference position when finishing the initializing operation of the motor. SOLUTION: A stopping detecting means detects stopping time on the basis of both output signals of a vehicle speed sensor 63 for detecting a vehicle speed of a vehicle mounted with a continuously variable transmission and an input rotation sensor 64 for detecting an input rotating speed of the continuously variable transmission. A motor initializing operation means performs return operation in the other direction up to a reference position after actuating a motor once up to a unidirectional mechanical actuation limit position when detecting stopping time of the vehicle by the stopping detecting means.  A stopping time motor command value initializing means initializes a command value to the motor as the reference position when finishing initializing operation of the motor by the motor initializing operation means to thereby prevent inconvenience such as imparting a sense of incompatibility to a driver by initializing the motor by erroneously detecting stopping time at traveling time.

Title: Zero-phase voltage detector
Inventor: MISHIMA KENSHICHIRO
IPC: G01R31/12
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To simply and economically constitute a zero-phase voltage detector for line-to-ground faults of non-grounded three-phase high-voltage distribution lines. SOLUTION: A current transformer 1-2 for current detection is placed in the common grounding conductor 1-3 of three arresters 1-1 for lightning protection, placed between non-grounded three-phase high-voltage distribution lines R, S, T and ground. A zero-phase voltage detector is thereby composed of the arresters 1-1 and the current transformer 1-2. The output of the current transformer 1-2 is used as detection output. When an equivalent circuit of the arresters 1-1 for lightning protection is given by parallel connection of high resistance and a capacitor, it can be also used as a component of the zero-phase voltage detector. This reduces the number of component parts dedicated to detection, and prevents degradation in the insulation reliability of the high- voltage distribution lines that would result if any dedicated part were installed.  In addition the arresters 1-1 allow the execution of intended lightning protective operation.

Abstract: PURPOSE:To relieve thermal and pressure stress at the time of bonding by forming a bump of a protruding layer composed of heat resistant resin and a metal layer on the surface thereof. CONSTITUTION:After forming an aluminum layer on a semiconductor substrate 11, photosensitive resin is formed on the entire surface, and after the aluminum layer has been etched leaving only a pad electrode region, the photosensitive resin is removed. Subsequently, an insulation film 13 is formed on the entire surface including the pad electrode 12, and the insulation film 13 is etched by using the photosensitive resin to form an opening 30. Then after a heat sensitive resin film 14 is formed on the entire surface of substrate 11 and further the photosensitive resin is formed, the photosensitive resin is removed leaving only the bump formation region. With the photosensitive resin 15 used as a mask, the resin film 14 is etched to form a protruding film 16, and photosensitive resin 15A is again formed on the entire surface of the substrate 11 while an opening equal in size to the opening 30 is formed. Then, with the photosensitive resin 15A used as a mask, Pd, Sn, or the like is ion-implanted to form a catalyst layer 18. The photoresist resin 15A is removed to form an Au film 19 of the catalyst layer 18 thus forming a bump. Consequently, cracks occurring on the substrate and the insulation film can be reduced.
