IPC: B21D5/12
Filed: 1987-12-03
Abstract: PURPOSE:To facilitate the conversion of loose rolling and non-loose rolling by arranging a rotation transfer member between the member rotating with a shaft or integrally with the shaft and a loosely rolling roll piece and integrally rotating the loosely rolling roll piece and rotation transfer member. CONSTITUTION:In the loosely rolling roll arranging a driving roll piece 3 at the center part and having loosely rolling roll pieces 6, 6 via roller bearings 5, 5 on upper and lower sleeves 4, 4 respectively a cover 9 for rotation transfer of the structure integrating a bearing inner ring presser 7 and outer ring presser 8 is prepd. and set. The cover 9 is fitted via a key 2 onto a shaft 1 at its inner diameter and held by a bolt 12 by charging a key 10 into an outer peripheral notch 10a.

IPC: G02F1/37
Filed: 1990-11-15
Abstract: PURPOSE:To modulate a 2nd harmonic output by adjusting the phase matching by an electric field which is impressed on an electrode installed on a non-linear optical material. CONSTITUTION:Non-linear optical crystal KNbO34, etc., provided with the elec trode 9 for impressing the electric field is arranged on the optical axis of omegalight in an external resonator of a triangle ring. The KNbO34 is held at a temperature capable of performing the phase matching by a Peltier element in advance, and the light emitting intensity of 2omega light is modulated by the electric field which is impressed on the electrode 9. At this time, a resonating mirror for making omega light incident is inclined with reference to the optical axis of the omega light so that the reflected omega light may not return to a light source LD. Besides, the stabilization of the frequency of the LD is performed by returning scattered weak light generated in the external resonator to the LD. Thus, the light emitting intensity of the 2nd harmonics can be accurately con trolled.

Title: Method and device for detecting and specifying trouble of machine body movement sensor
Inventor: SUDO NAOKI
IPC: G01C21/00
Filed: 1990-11-14
Abstract: PURPOSE:To prevent lowering of sensitivity owing to a time and to perform rapid detection by detecting and calculating a trouble through a method (a relation formula between sensor/SPRT method) employing a dynamic relation formula between sensor outputs and statistical calculation. CONSTITUTION:A trouble specifying calculating means 1 with rate sensors P, Q, and R for rolling, pitching, and yawing of a machine body and orientation sensors for orientation angles theta, phi, and psi of pitch, roll, and an azimuth determines a trouble tolerance ratio. A deciding means 2 decides the negative and the positive of the ratio and a control means 3 sets the trouble tolerance ratio to zero when the ratio is positive and performs calculation from the beginning. Since, in a conventional method, detection and calculation of a trouble are effected based on one fixed hyposesis, the more a difference between the hyposesis and an actual trouble time is increased, the more sensitivity is decreased. Since constitution of (T1<T2) sets the ratio to zero when the trouble tolerance ratio is positive, a trouble time on the assumption is updated into a present time and the occurrence of a trouble is waited in a state that best sensitivity is always kept. (T1=T2).

Abstract: PROBLEM TO BE SOLVED: To facilitate bending separation from a lead retaining part, without bending it many times by stretching the width of a lead, and largely arranging the lead in the vicinities of both ends of a long edge direction of a rectangular half etch part. SOLUTION: At the center of a lead bending separation part 14 of a lead 12, a rectangular half etch part 16, e.g. whose short edge is set to be almost 0.5 times a width A of the lead, and whose long edge is set to be almost 1.2 times the width A of the lead is arranged. In the vicinities of both the ends of the long edge direction of the rectangular half etch part 16 which is formed at the center of the lead bending separation part 14, the width of the lead is stretched, and the lead is largely arranged. That is, the size of the section in the widthwise direction of the lead becomes sufficient. As a result, bending from the lead bending separation part is not generated in an etching process for manufacturing the lead frame and a post-working process. Bending separation from a lead retaining part can be facilitated by bending the lead frame at the lead bending separation part 14.
