Patent JP-S6094780-A (JP)
Title: Constant-voltage diode
Inventor: TOIDA HIROTOSHI
IPC: H01L29/36
Filed: 1983-10-28
Abstract: PURPOSE:To eliminate the influence to the constant voltage characteristic even if a semiconductor substrate is damaged or notched by forming the substrate of a constant-voltage diode in a negative bevel structure. CONSTITUTION:An Si substrate 11 has three layers of a p type layer 11a, an n type layer 11b and an n<+> type layer 11c, p type impurity and n type impurity are diffused from the main surface side to the thin n type Si plate to form a p-n-n<+> type layer structure, and the region to which the impurity is not diffused becomes the layer 11b. The area of the main surface of the layer 11a side becomes smaller than that of the main surface of the layer 11b side, and the side periphery of te substrate 11 is inclined to the main surface. A p-n junction J formed of the layers 11a and 11b is parallel to the main surface, the exposed end of the junction J is acute at the layer 11a side in the angle formed with the side periphery, and the layer 11a has higher impurity density than the layer 11b. Accordingly, the Si substrate 11 has negative bevel structure. The portion that damage or notch feasibly occurs during the manufacturing steps of the substrate 11 is the main surface peripheral edge of the layer 11c side, and even if the damage or notch occurs, it is separated from the junction, thereby hardly causing the decrease in the characteristics.

Title: Small-sized motor
Inventor: SATO NAOJI
IPC: H02K7/10
Filed: 1993-07-22
Abstract: PURPOSE:To lessen torque which rotates an output shaft from outside, by causing an input-side rotor and the output-side rotor to couple with electromagnetic force, and stopping the current flow into the coil of an electromagnetic clutch. CONSTITUTION:When current flows in the stator 1 of a motor and the coil 14 of an electromagnetic clutch, magnetic flux circulates through a cylindrical yoke 11 and a disklike yoke 12 and rotors 6 and 7. And the rotors 6 and 7 are united like a single body since the magnetic reluctance of the gaps is minimum at positions where the respective protrusions of the rotors 6 and 7 are opposed, and the rotation of the rotor 18 of the motor is transmitted to the output shaft 9 through the medium of a reduction gear 3 and an output gear 15. When the current flow to the coil 14 of the electromagnetic clutch is stopped, magnetic flux circulating the rotors 6 and 7 distinguishes, and torque is not transmitted. Accordingly, the output shaft 9 becomes freely-rotatable irrespective of the rotation of the motor.

Abstract: PURPOSE:To obtain good electromagnetic conversion efficiency over a wide range from a low frequency to high frequency range by forming thin magnetic metallic films into multi-layered constitution by the intervention of nonmagnetic insulator layers therebetween and non-paralleling the opposed surfaces of the thin magnetic metallic films and magnetic ferrites. CONSTITUTION:The thin magnetic metallic films 22, 24 are made into the multi- layered constitution by dividing the films in the direction approximately orthogonal with a working gap 6 and interposing the nonmagnetic insulator layers 26 therebetween. The joint surfaces of the thin magnetic metallic films 22, 24 and the magnetic ferrites 2, 4 are set non-parallel with the working gap 6. Since the thin magnetic metallic films 22, 24 are constituted into plural layers, the suppression of eddy current is possible and since the joint surfaces of the respective thin magnetic metallic films 22, 24 and the magnetic ferrites 2, 24 of the respective layers are set non-parallel with the working gap 6, the generation of the shape effect arising in the low frequency range is suppressed at the time of reproducing the recording signals from a magnetic recording medium. The good electromagnetic conversion characteristic is thereby obtd. over a wide range from the low frequency to the high frequency range.
