Title: Thin film semiconductor and production of semiconductor device
Inventor: INAKANAKA HIROSHI
IPC: H01L21/20
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To produce a thin film semiconductor with excellent crystallinity at a low cost in high volume by forming a porous semiconductor layer having a layer with lowered strength on a semiconductor substrate, vacuum-chucking the backside of the semiconductor substrate and separating a semiconductor thin film formed on its surface from the semiconductor substrate. SOLUTION: The surface of a semiconductor substrate 11 is made to be anodic so as to form a porous layer 12. The substrate 11 is annealed in an atmosphere of hydrogen and an Si is grown epitaxially by using an SiH4 as a material gas, so as to form a semiconductor thin film 13. A supporting substrate 31 is bonded to the surface of the thin film 13 with an adhesive agent having a large adhesive strength. On the other hand, the backside of the substrate 11 is sucked to a vacuum chuck 32, and the bonded supporting substrate 31 is pulled up as to be separated from the substrate 11, thereby peeling off the thin film 13. Thus, the thin film 13 in the weakened porous layer 12, especially in the porous layer 12, is separated from the substrate 11.

Abstract: PURPOSE:To enable an Al thin film to be formed in a specific region at sufficient film forming rate without deteriorating the selectivity thereof by a method wherein the temperature of a substrate and the partial pressure of dimethylaluminum hydride gas are respectively specified in specific ranges. CONSTITUTION:A material gas containing dimethyl aluminum hydride (DMAH) is fed to a reactor vessel to deposit Al or Al alloy on the specific region of a substrate 10 so that pure Al or Al alloy film may be formed.

Title: Alternator for vehicles
Inventor: KANAZAWA HIROYUKI
IPC: H02K19/36
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To suppress leakage flux by a method wherein the lengths of claw-type poles are reduced in order to increase a magnetic reluctance between the claw- type poles. SOLUTION: In order to avoid the generation of leakage flux between an N-pole and an S-pole, the lengths of claw-type poles 3 are reduced so as to have the tip parts of the claw-type poles 3 positioned at about the center of a stator core. With this constitution, the area of a magnetic path between the poles is reduced, a magnetic reluctance between the poles is increased, and the generation of the leakage flux is suppressed. As the flux is hardly concentrated to the tip part of the claw type pole 3 in relation to the magnetic reluctance and a flux density at the tip part of the claw-type pole 3 is small, even if the tip part of the claw-type pole 3 is shortened a little, the performance hardly influenced. That is, the tip parts of the claw-type poles 3 are positioned at about the center part of a field winding 4, in other words, the center part of the stator core 8. Optimum dimensions of the claw-type poles are such that the leakage flux is reduced while an effective magnetic path cross-sectional area is not reduced much and the length of the claw-type pole is designed to be about a half of the length of the stator core.

Abstract: PURPOSE:To improve unusual condition of an engine by means of the abnormality detecting circuit and the change-over circuit used for monitoring the behavior of  each processor, in case where one of the devices is abnormal, both ignition coils  driven by a normal device, and its ignition timing is set to be optimum. CONSTITUTION:When they are normal, respective ignition coils 9, 10 are actuated by processors 3, 4. For example, when the processor 4 becomes abnormal, the unusual condition is detected by an abnormality detecting circuit 12, and a change- over circuit 14 drives the ignition coil 10 in compliance with ignition signals transmitted from the processor 3. The optimum ignition timing varies depending upon either case of changing the ignition timing or synchronizing the ignition. In consequence, when any abnormal condition is detected, the ignition timing is set to be  optimum as being synchronous ignition. Thus, at the time of abnormality in the  processors 3, 4, the unusual condition of the engine can be retained within minimum.
