Title: Coated superhard alloy tool
Inventor: FUJIMORI NAOHARU
IPC: B23B27/14
Filed: 1981-02-18
Abstract: PURPOSE:To manufacture a coated superhard alloy tool with superior wear and sheat resistance at a low cost by coating the surface of a superhard alloy tool with laminated layers of Al2O3 having different grain sizes with Ti carbide, nitride carbonitride or boronitride in-between. CONSTITUTION:The surface of a superhard alloy tool formed by binding metallic carbide or carbonitride grains of high hardness with an iron group metal is coated with a layer of Ti carbide, nitride, carbonitride or boronitride. The coated tool is then heated and held in a mixed gaseous flow of AlCl3, H2, CO2 and CO. By regulating the heating temp., the pressure of the mixed gaseous flow and the holding time, an inner layer contacting with the Ti compound, an intermediate layer and an outer layer are laminated with hard Al2O3 having <=1mum, 1-5mum and <=1mum grain sizes in 0.5-1mum, 2-4mum and 0.5-3mum thicknesses, respectively. Thus, a superhard alloy tool with superior heat and wear resistances is obtd. using inexpensive Al2O3 in place of expensive metallic carbide, etc.

Title: Production of reflection mirror
Inventor: MIYAWAKI KEIZO
IPC: F24S23/70
Filed: 1987-02-04
Abstract: PURPOSE:To obtain a reflection mirror superior in shock-resisting capacity by interposing a thermosetting adhesive between a glass plate having a reflecting surface and a base plate whose coefficient of linear expansion is higher than that of this glass plate and joining them by heating and gradually cooling them to a normal temperature. CONSTITUTION:A thermosetting adhesive 12 is interposed between a base plate 1 and a glass plate 2, and they are put on a supporting base 14 in a furnace 13 and the heated at about 120 deg.C for several hours to join the glass plate 2 to the base plate 1. At this time, the thermosetting adhesive 12 interposed between the base plate 1 and the glass plate 2 is hardened. If they are gradually cooled to a normal temperature in the furnace 13, compressive stress remains in the glass plate 2 because the coefficient of linear expansion of the glass plate is lower than that of the base plate 1. Thus, a proportion of tensile allowable stress to compressive allowable stress of the glass plate is increased, and as the result, the reflection mirror superior in shock-resisting capacity is obtained.

Abstract: PROBLEM TO BE SOLVED: To increase the mutual conductance of active devices by using a current flowing from a drain of the 1st active device for a 2nd active device again without increasing the current and increasing noise. SOLUTION: An RF low noise amplifier(LNA) is made up of a 1st stage 10 and a 2nd stage 20 and the two stages act in the similar method.

Furthermore, a capacitor CB branches a source of the device M1 to earth at a high frequency. The drain current of the device M1 is used again by the device M2 . Thus, the mutual conductance gm is increased without increasing current consumption in contract with a common use source amplifier consisting of the device M1 or M2 only.

Filed: 1994-02-22
Abstract: PURPOSE:To confirm the completed state of agitation at a glance, and use a display body as a handle by providing the display body with a vane so as to be freely detachable, and keeping holding power between the display body and the vane at a level equal to or larger than holding power necessary to support the weight of a cover and the vane. CONSTITUTION:A detector 27 with a display section 29 is rotatably fitted to the bearing section 26 of a cover 23. Also, a vane 33 is detachably suspended from an engagement tooth 32 on the lower end of the cylindrical section 28 of the detector 27. A material rotates in contact with the vane 33 and the display section 29 is thereby caused to rotate. Thereafter, the air or water contained in the material, for example, butter is removed and the material no longer contacts the vane 33, thereby stopping the display section 29. In this state, the completion of a process for the butter is reported. Also, holding power between the engagement tooth 32 of the detector 26 and the vane 33 is set at a level higher than holding power between a packing 25 and a vessel 4 at the coupling section where the cover 23 is fitted to the vessel 4. As a result, even when the cover 23 is removed, using the display section 29 as a handle, the vane 33 is not detached to fall on the material in the vessel 4.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a gap in a connection part between bores in two members when the two members, at least one of which is constructed of resin, are connected together. SOLUTION: For connecting a resin throttle body 1 and a resin intake manifold 2 together, their flanges 5, 11 are integrally fastened together by means of a bolt 12. While a throttle body 1 is connected to the intake manifold 2, a thin metallic pipe 14 is forcibly fitted over the connection part between a bore 6 of a throttle body main body part 4 and a bore 13 of the intake manifold 2. In this way, even if the bores 6, 13 of the resin throttle body 1 and the resin intake manifold 2 or the flanges 5, 11 of them are deformed, this deformation can be corrected by means of the metallic pipe 14, and consequently, circularity of both bores 6, 13 can be maintained while smooth connection can be carried out without any gap.
