Filed: 1985-04-01
Abstract: PURPOSE:To prevent the occurrence of wrinkles in a back plate and the leakage of a heat insulator by a method in which when placing the back plate on the folded portion of a surface plate, two back plates are placed and pressed by upper and lower surface plates, one back plate is then removed out, and heat insulator is packed into the space so formed between the surface and back plates held by the surface plates. CONSTITUTION:In placing a back plate 4 on the folded portion 1c of a surface plate 1, two back plates 2 are once placed on the portion 1c and flatly pressed by upper and lower surface plates 5 and 6, and one back plate 4 is removed out. The surface plate 1 and the remaining back plate 4 are held by the surface plates 5 and 6 and a heat insulator 7 is packed into the space formed by the plates 1 and 4. Since the upward angle by spring back in the formation of the folded portion 1c of the surface plate 1 becomes smaller, sliding between the back plate 4 to be extended when packing the insulator 7 and the folded portion 1c can thus be smoothly made. Therefore, no wrinkles occur in the back plate 4 and no leak of the insulator 7 takes place.

Title: Radial tire
Inventor: UEMURA YUKIHISA
IPC: B60C11/00
Filed: 1978-06-07
Abstract: PURPOSE:To prevent abnormal wear of sholder areas of a radial tire by supplementing the thickness of each rubber layer corresponding to the shoudler areas of the tread with further rubber to prevent the shoulder portions from localized deformation. CONSTITUTION:The present radial tire comprises a tread portion 5 extending to center areas 7, and outwardly extending shoulder areas 8, 8, which tread portion 5 has a range W' that is calculated by subtracting, from 50% of a width W of the tire in a condition of the tire filled with air pressurized as prescribed, 20% of a hight H of the tire in said condition. Outward of the surface beyond the tread of each center area 7, the thickness of shoulder areas 8, 8 is progressively increased from each border B adjacent to the center areas 7 toward each wall portion 6, each point c being determined by the value corresponding to an amount d to be locally deformed at the shoulder portion, and the line extending from the point c inwardly and diagonally being tangent around B to the radius of curvature of the center areas 7. The present tire is vucanized and molded to form rubber layers 9 using a mold with a tread having a curved surface difined by a radious curvature larger than the first-mentioned radius of curvature.

Title: Phase locked loop
Inventor: NISHIZAWA TATSUYA
IPC: H03L7/093
Filed: 1994-04-07
Abstract: PURPOSE:To ensure both the fast response and the signal purity of a phase locked loop by inserting diodes connected in parallel with their polarities opposite to each other as a nonlinear circuit between the stages of the 1st and 2nd LPFs. CONSTITUTION:The diodes D1 and D2 connected in parallel with their polarities opposite to each other as a nonlinear circuit are inserted between the stages of the 1st and 2nd LPFs 20 and 21. When the phase is locked, no current virtually flows and therefore the impedance of each diode is very high. Then the time constant of the rear end 2nd LPF is increased with its cut-off frequency reduced. This greatly contributes to the smoothing of both pulse and noise components outputted from a phase comparator 1. When the frequency is switched, the comparator 1 functions to change the frequency of a voltage control oscillator 2. Thus the DC potential differences are produced at the points before and after a loop filter. Then one of both diodes is forwardly biased and its impedance is reduced. As a result, the capacitor of the rear end 2nd LPF is quickly charged and discharged and the fast response is ensured for a phase locked loop.

Title: Remote displacement detector
Inventor: OZAWA TAMANE
IPC: G01D5/30
Filed: 1986-03-29
Abstract: PURPOSE:To detect the displacement of a matter at a remote area without providing an energy source such as a light source to an article to be measured, by mounting a reflecting body on the article to be measured and detecting the position of reflected beam. CONSTITUTION:The laser beam emitted from the beam source 5 of a measuring device 3 is reflected by a half mirror 7 while the reflected beam is incident to the corner cube 1 mounted on an article to be measured to be reflected to the direction parallel to the incident beam. Then, the reflected beam transmits through the half mirror 7 to be formed into an image on a two-dimensional beam position sensor 11 by a lens 9. The image forming position on the sensor 11 is changed by the movement of the corner cube 1 and the quantity of displacement thereof comes to two times the moving quantity of the corner cube 1 to the direction crossing beam at a right angle. However, the displacement of the image forming position is regardless of the movement or inclination of the corner cube 1 in the optical axis direction and, therefore, the displacement of the article to be measured in the direction crossing beam at a right angle can be detected from the displacement quantity of the reflected beam on the sensor 11.
