Title: Synthetic resin holder for rolling bearing
Inventor: TAMAKI YASUSHI
IPC: B29C45/14
Filed: 1997-10-07
Abstract: PROBLEM TO BE SOLVED: To improve strength by forming a flow passage for a synthetic resin on an inner or outer diameter side of a holder correspondingly to a pocket of the holder, without interfering with the pocket at the time of injection molding, injection-molding the holder, and then removing the flow passage for the synthetic resin. SOLUTION: Resin 2 is charged from a gate 4 formed on a disc 3. The resin 2 charged from the gate 4 is flowed through a flow passage 6 formed on an inner diameter side of a pocket 5. Due to the presence of the flow passage 6, the resin 2 is smoothly charged to the opposite side to the gate in each pocket. Weld is generated partially in the pocket, so that strength is improved. The pocket 5 can be formed by arranging a slide core type die. A disc gate method is selected as a charging method. In such a case, flow of the resin is terminated at a disc end. Clear weld is hardly generated, for easily securing improvement of strength.

Title: Coaxial connector
Inventor: OONISHI TOMOYOSHI
IPC: H01R13/646
Filed: 1990-10-12
Abstract: PURPOSE:To prevent rotation of a center conductor penetrating an insulation member of a coaxial connector by setting the diameter of the center conductor at a part larger, and forming a pair of flat surface parts in the outer circumfer ence at the part. CONSTITUTION:The diameter of a part 3a of a center conductor 3 penetrating an insulation resin member 4 of a coaxial connector 1 is set larger than that at the other parts. Flat surface parts 5 are formed facing each other at the part. Because the sectional surface of this part 3a is not circular, rotation of the center conductor 3 to the member 4 can be prevented securely. For the part where the parts 5 are formed, its capacity component is reduced for that. Because the diameter at the part is larger than at the other parts, however, the capacity component to a conductor 2 is larger, and the capacity component is balanced as a whole, thereby the characteristic impedance can be matched.

Abstract: PROBLEM TO BE SOLVED: To increase the breakdown strength of power semiconductor transistors and lower the loss by a method wherein an AlN layer which comes into contact with a conductive layer of SiC and has a lattice constant, or its mixed crystal is epitaxially grown to form a superior interface with a few interface levels, and an electrode for controlling a current is provided in its upper part. SOLUTION: A buffer layer 12 is epitaxially grown on a semi-insulated SiC substrate 11, and a p type conductive layer 13 and an n type layer 14 for a source electrode 16 and a drain electrode 17 are grown. Thereafter, a part forming a gate electrode 18 is etched up to the p type conductive layer 13, and the AlN insulator film 14 is deposited by a MOCVD method to form the source electrode 16, the drain electrode 17, and the gate electrode 18. In an interface level between an insulator film 15 and the p type conductive layer 13, lattice mismatch between SiC and AlN is small and also the AlN layer is epitaxially grown at high temperature. Therefore, it is possible to obtain a superior interface with a uniform film thickness and a few interface levels.  For this reason, if a positive potential is applied to a gate electrode, there occurs an inverted layer 19 near the interface in which electrons are stored.

Title: Vertical insulated gate field effect transistor
Inventor: TAKAO NORIYUKI
IPC: H01L29/78
Filed: 1987-10-30
Abstract: PURPOSE:To realize a longitudinal IGFET wherein a parasitic transistor does not readily operate in the absence of an increase in ON-resistance by a method wherein a second semiconductor region of one conductivity type higher in impurity concentration than a first semiconductor region is formed on the lower section of a well region in contact with a drain region. CONSTITUTION:In contact with a drain region 6 positioned under a well region 2, a high-concentration second semiconductor region 1 is formed, which is same as the drain region 6 in conductivity type. In such a design, breakdown strength is lower in the second semiconductor region 1 than in the surface, which causes a breakdown current to flow not on the surface but through the second semiconductor region 1. No parasitic transistor operates because there is no current in a base resistor, which contributes to the prevention of a thermal runaway. There is no increase in ON-resistance because there is no change in the gate width.

Abstract: PURPOSE:To secure endpoint detection and to simplify structure of a chamber, by forming an endpoint detection signal by the use of a change in self-bias which is generated by a plasma potential or a sheath current in a device for plasma etching or reactive ion etching.
