摘要： PURPOSE:To enable in-process measuring during mechanical fabrication and measure the displacement accurately. CONSTITUTION:In a metallic cylinder 2 arranged facing to a measuring object 10, liquid 5 is sealed and ultrasonic wave 4 emitted from a transmission sensor 3 at the upper part passes through a beam splitter 6 and is focused at a spot with an object lens 8 to be guided in the surface of the measuring object 10. The lower part of the metallic cylinder 2 is separated and in the separated cylinder, a linear focus lens 11 is arranged, liquid 7 is sealed in and a reception sensor 14 is fixed at the end. The reflection wave from the surface of the measuring object 10 after passing through the object lens 8 in the opposite direction is reflected by a beam splitter 6, passes through the linear focusing lens 11 and reaches a reception sensor 14. By this, the distance change between the object lens 8 and the measuring object can be replaced with cross sectional shape change of the ultrasonic beam at the reception sensor position. The reception sensor 14 is constituted so as to output the voltage according to the cross sectional shape of the ultrasonic beam.

摘要： PURPOSE:To separate a skeleton from a cover object without mixing in each other by processing a framed structure, comprising the skeleton and the object for covering this skeleton, of an automobile seat or the like by a cutting device with a water jet serving as a cutting means. CONSTITUTION:In the case of dismantling an automobile seat formed by covering a metal-made skeleton material 9 with a seat material by a cushion material coated with a seat cover 12, first a nozzle moving mechanism part 3 of mounting a water jet nozzle 1 and a sensor 2 is arranged in a cut starting point to start cutting by water jet. By the sensor 2, the skeleton material 9 is detected for whether it is provided or not, and a signal of showing a shape of the actual thing is compared with a dimensional data of basic shape relating to a seat read from a memory 4, to correct the dimensional data. Based on the dimensional data after correction, so as to always prevent an inching jet direction of the nozzle 1 from being displaced from the skeleton material 9, moving the nozzle moving mechanism part 3 is controlled to perform sure separation of the seat material.

摘要： PURPOSE:To prevent a hydraulic material, which is used for forming, from sticking to a forming material, to prevent the forming material from being taken out with the hydraulic material stuck to it and to improve workability, in reference to a hydraulic press forming machine by which a thin plate is formed. CONSTITUTION:After forming dies like a male base 3, a hydraulic chamber 4, etc., are attached and fixed in the slide 1 and a bolster 2 of the press respectively, the forming material 9 is arranged on the upper surface of a lower blank holder 8. The fluid to be used is a mixture of an adequate amount of a thickener, rust preservative and surfactant with water. By the effect of the surfactant, the surface of the forming material is hardly wet even when the surface is brought into contact with the fluid during forming. The fluid 10 is filled in the hydraulic chamber by a supply device 12. An adjusting apparatus for supply and forming pressure may be an ordinary water and oil pressure apparatus since the mixed quantity of the thickener is small and the viscosity of the fluid is low. The press thus structured is operated to lower the slide and push down the forming material the tip end part 3' of the male die; consequently, the fluid pressure in the hydraulic chamber is raised, and the forming material is press-formed in the shape of the male die.

摘要： PURPOSE:To improve the wear resistance or the like of a sintering material at a high temp., in a sintering material for a tool constituted of hard perticulate matters of cubic BN or the like and a metallic compound series bonding phase by preliminarily coating the hard perticulate matters with a film contg. metals in the bonding phase components. CONSTITUTION:Hard perticulate matters 1 of cubic boron nitride, diamond or the like and bonding phase component 3 selected from the nitrides, borides and carbides of metallic elements or their combined compounds (e.g. TiN) are prepd. Then, the hard perticulate matters 1 are coated with a film 2 of the same components as the bonding phase components (e.g. TiN film) or is coated with a film 2 of a compound other than that of the metallic elements in the bonding phase components. Next, the hard perticulate matters 1 coated with the film 2 and the bonding phase components 3 are mixed to manufacture a sintering material for a tool. In this way, because the surface of the hard perticulate matters 1 is coated with the film 2, the adhesion between the hard perticulate matters 1 and the bonding phase 3 improves, and as a result, its sinterbility improves, by which a cutting tool or the like to be manufactured shows high wear resistance.

摘要： PURPOSE:To improve wear resistance particularly at high temp. by mixing granular cubic boron nitride, titanium nitride, and a granular mixture of aluminum oxide, zirconium oxide, and acicular crystal of silicon carbide in the specific proportion. CONSTITUTION:This sintering material has a composition which consists of 40-70vol.% granular cubic boron nitride, 15-45vol.% titanium nitride to be the essential component of a binding phase, and 15-25vol.% of a granular mixture of aluminum oxide, zirconium oxide, and acicular crystal of silicon carbide to be accessory component of the binding phase and in which the composition of the accessory component of the above-mentioned binding phase contains 1-5vol.% aluminum oxide and 5-15vol.% acicular crystal of silicon carbide. By using the above-mentioned sintering material, the holding capacity of the CBN grain in the binding phase is improved as compared with the conventional one, wear resistance particularly at high temp. is improved, and also chipping resistance is improved since a sound sintered compact can be obtained.

摘要： PURPOSE:To form a product having plural formed parts different in diameter to each other by setting all pitch intervals made by projecting parts and recessed parts on the respective form-rolled surfaces to the pitch interval of the form- rolled surface surface which forms a formed part having the largest diameter. CONSTITUTION:When a form-rolled product W having plural formed parts 2,3 different in diameter is formed, the dies 10,20 are used which formed other form-rolled surfaces 12,22 through the pitches of a projecting part and a recessed part formed on form-rolled surfaces 11,21 to work a formed part 2 having the largest diameter. When the stock W1 is form-rolled, the stock W1 is rolled along the dies 10,20 based on large diameter part 2 receiving relatively strong restraint from the dies 10,20. Consequently, when the stock W1 receives plastic working in rolling contact along the working surfaces of the form-rolling dies 10,20, the stock W1 moves surely so that the stock W1 and the dies 10,20 take prescribed positions, does not shift and can work a form-rolled product W with high precision.
