Title: Optical rotation detecting mechanism
Inventor: NAKAI KATSUJI
IPC: G01D5/347
Filed: 1983-04-25
Abstract: PURPOSE:To detect exactly a rotation by a titled mechanism which is small- sized and inexpensive, by placing oppositely the first and the second optical fibers on one end face of a refractive index distribution type lens, and emitting and photodetecting a light which is emitted from the first optical fiber and made incident to the second optical fiber, by the refractive index distribution type lens. CONSTITUTION:A lens 25 has a length of 1/4 pitch of a snake light cycle of a light, therefore, a light emitted into the lens from a projecting optical fiber 12 is projected as a parallel light roughly vertical to this end face from the end face of a disk 4 side of the lens 25. That is to say, the lens 25 functions as a collimator. Accordingly, when a slit 6 is positioned on a straight line for connecting the lens 25 and a slit 23, a light projected from the lens 25 passes through the slit 6 and the slit 23, it is reflected by a passive reflector 24, passes through the slit 23 and the slit 6 again, and is made incident into the lens 25 as a parallel light roughly vertical to the end face of the lens 25. In this case, a disk 22 functions as a mask of the passive reflector 24, and the slit 23 functions as a diaphragm of a light which is projected from the lens 25 and photodetected by the lens 25.

IPC: H01L23/50
Filed: 1987-03-25
Abstract: PURPOSE:To enhance the transfer and positioning accuracy by magnetizing an external lead of a package for a semiconductor device. CONSTITUTION:A semiconductor device is housed inside a box-shaped ceramic substrate 1 and is then connected to external leads 2 composed of a magnetic material (e.g., an iron-related metal) according to a dual in-line system. These external leads 3 are magnetized in advance. A welding ring 2 is provided for hermetic sealing with a metal cap. If a package is transferred on a transfer rail 4 composed of the magnetic metal during a production process, the package is subjected to a damping force due to a magnetic force which interacts between the external leads 3 and the transfer rail 4 with each other; accordingly, a difficulty in transferring and positioning the package as occurred in a conventional method is eliminated because the package does not slide too easily on the rail.

Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a multilayer capacitor which can reduce generation of improper insulation caused by water penetration and also can suppress generation of such structural defect as crack at the time of soldering. SOLUTION: The multilayer capacitor 20 comprises an element body 23 and a pair of external electrodes 24. The element body 23 is made up of dielectric layers 21 and internal electrodes 22 alternately stacked and then burned. The pair of external electrodes 24 are connected in parallel to the internal electrodes 22 alternately at both ends of the element body 23. The body 23 is burned so as to have locally different sintered densities to provide multilayer capacitor 20. Therefore, in a part of the element body 23 having low sintered densities, fine air layers are dispersed between the dielectric layers so that, when a stress occurred, the air layers cause the stress to be reduced.  In a part of the element body 23 having high sintered densities, no fine air layers are present between the dielectric layers so that the body part becomes compact, thereby preventing external water penetration.
