Title: Three-dimensional measuring instrument
Inventor: ISHIHARA MITSUHIRO
IPC: G01B11/24
Filed: 1990-03-13
Abstract: PURPOSE:To easily measure three-dimensional coordinates by performing operations to a local area including an edge part of an object to be measured within an image, and determining the position of the edge with not larger than the resolving power of pixels. CONSTITUTION:An image of an edge of an object to be measured is adjusted to be within a local area. While a lens barrel is moved in a direction of the Z axis, the variance of the luminance of the image is detected. In other words, when the luminance of the image is expressed by f(x,y), formulae I-III hold. In the formulae, N is the total number of pixels within the local processing area. A point where N is a maxi mum is regarded as the focusing position, so that the position of the local processing area in the Z direction is obtained from the moved distance. Thereafter, the focused positions m1, m2 and m3 (formula IV) are obtained. If one regards that the ideal edge for which the obtained first, second and third order moments become equal is the desired edge, it is given by formula V, in which P1+P2=1 and P1 and P2 are the ratios of occupation of h1 and h2 repectively, in the entirety. When equation V is solved, formulae VI, VII and VIII are obtained, and the position of the edge is deter mined from P1. Accordingly, three-dimensional coordinates can be measured in a simple manner without considering a threshold value or the change of the illumination.

IPC: H01L27/04
Filed: 1994-03-04
Abstract: PURPOSE:To provide an in expensive light irradiation position detecting sensor using a thin film microelement. CONSTITUTION:In a position detecting sensor 10, an air-core coil 2 made of a conductor is formed on an insulating substrate 1. The air-core coil 2 is formed into a ladder coil pattern by etching a conductor formed on the insulating substrate 1 such as a glass substrate. On the coil pattern 2, a photo conductive film 3 is formed. And, on the photoconductive film 3, an upper electrode 4 is formed. This upper electrode 4 is a transparent conductive film which allows the light of wavelength used to transmit. Further, on the upper electrode 4, a light-transmission glass substrate 5 is provided. With this, the resistance of photoconductive film 3 is decreased due to light irradiation, a continuity between the upper electrode 4 and the coil is permitted, and the substantial dimension of the coil changes, so that the inductance of the coil changes. So, the position of light irradiation is obtained based on the inductance value when the light is cast, from relative relation between the inductance value and position when the length of air-core coil 2 is changed.

Title: Inertia supercharging controller of engine
Inventor: SUZUKI HIDEKAZU
IPC: F02B75/20
Filed: 1985-03-25
Abstract: PURPOSE:To improve engine efficiency, by providing a communication path in each intake system, which performs inertia supercharging by dividing into two groups the intake system of an engine having plural cylinders, and setting an opening and closing valve, provided in the communication path, to be opened about in the center of an intake stroke so as to reduce a large negative pressure generated in this timing of the intake stroke. CONSTITUTION:An engine 3, having plural cylinders 2, is divided into two blocks B1, B2 forming in every block independently intake systems 4A, 4B, and their upstream joins together forming an intake pipe 4. The engine, providing a communication pipe 5 communicating with each intake system 4A and 4B, there provides an opening and closing valve 6 which synchronously opens and closes with a rotation of the engine. Each intake system has a shape suitable for inertia supercharging, but the intake system, increasing the pressure in the end of an intake stroke in each cylinder 2 but largely decreasing the pressure reversely in about the center of the intake stroke, generates a large pumping loss. An inertia supercharging controller, setting the opening and closing valve 6 to be opened in the timing such as in said intake stroke and unbalancing an intake pulsation, prevents the pressure from decreasing.

Title: Tray for drying powder
Inventor: TOYOSHIMA SHOGO
IPC: B65D1/34
Filed: 1990-03-12
Abstract: PURPOSE:To eliminate the difference of drying speed between powder on the side of the bottom surface of a tray and the powder in the side of the surface of the powder to make it hard to generate stress due to heat even when the tray is passed through the inside of a furnace of a high temperature by a method wherein the bottom surface of the main body of the shallow tray, which is extended slenderly into the width direction of the furnace, is bent inwardly to form a rib in the width direction of the furnace while the outside of the bottom surface of the tray main body is provided projectingly with hooks for engaging with a chain. CONSTITUTION:The bottom surface 3 of the main body 1 of a tray is bent inwardly to form ribs 4 in the width direction of a furnace whereby heat from the atmosphere in the furnace of a high temperature is facilitated to be transferred to powder body near the bottom surface 3 compared with a case in which the bottom surface 3 is flat and the difference of drying speeds between the powder in the bottom surface side of the tray and the powder in the side of the surface of the powder is reduced while drying speed of the powder can be increased. On the other hand, the tray is expanded due to heat when it is passed through the inside of the furnace of a high temperature, however, ribs 4 in the width direction of the furnace are formed on the bottom surface 3 of the main body 1 of the tray and, therefore, stress is hardly generated and the deformation of the bottom surface 3 can be prevented. Further, the tip ends of bent sheets 7 are inserted into hooks 6 to engage the main body 1 of the tray with a chain 5 loosely whereby the difference of thermal expansion generated between the main body 1 of the tray and the chain 5 can be absorbed by this part.
