Title: Iron core for electrical equipment
Inventor: ISHIBASHI AYANORI
IPC: H02K1/18
Filed: 1991-09-09
Abstract: PURPOSE:To reduce vibration and noise due to vibration between plates by applying an adhesive agent between tip iron plates on a tooth part of the stator core of a motor to fix the iron plates on the tooth part. CONSTITUTION:An adhesive agent 5 is applied between iron plates of tip parts 4 on a tooth part 3 in a stator side to fix the iron plates to one another. Consequently, the tooth part 3 is integrally formed as a motor total unit. Since the iron plates on the tooth part 3 are fixed, a clearance between the plates is prevented from spreading by repulsing the iron plates even when magnetic flux of the same polarity passes through the tooth part 3. The iron plate is prevented from also fluctuating due to a change of the clearance by changing the passing magnetic flux. Thus by generating no vibration between the iron plates of the tooth part 3, generation of vibration and noise of a motor is eliminated to decrease noise. Generation of looseness, or clatter due to vibration of the iron plate is eliminated to improve also durability of the motor itself.

Title: Manufacture of epitaxial wafer
Inventor: KANAMORI KATSU
IPC: H01L21/205
Filed: 1985-10-15
Abstract: PURPOSE:To stabilize the performance of elements preventing soft errors and latch up, and obtain an element forming layer containing no solid solution oxygen causing various defects, by performing epitaxial growth in two stages so as to forma layer of high density impurity being added necessary to an element circuit. CONSTITUTION:A P-type silicon single crystal substrate 1 is added with boron, and its specific resistance is smaller than 0.02OMEGA-cm. On this substrate, an epitaxial layer whose boron density is higher than 1X10<19>cm<-3> is formed as a first epitaxial layer 2. An epitaxial layer whose boron density is lower than 1X10<18>cm<-3> is formed as a second epitaxial layer 3. The use of a high density substrate is desirable to prevent latch up and soft errors, but the conventional substrate of about 0.01OMEGA-cm is not sufficient in the case of specified elements. Therefore, after an epitaxial layer containing boron of more than 1X10<19>cm<-3> is formed on a substrate with a necessary thickness, an epitaxial layer containing boron of low density is formed thereon, which is used as an active layer. As a subsidiary effect, an element forming layer can be formed in the state where oxygen impurity is not contained.
