Title: Casting mold for continuous casting and its production
Inventor: KUBOTA AKIRA
IPC: C23C28/00
Filed: 1982-06-12
Abstract: PURPOSE:To improve the durability of a casting mold of a precipitation hardening type copper alloy by mounting a nickel plating layer, a melt sprayed layer of a nickel-base self-fluxing alloy and a chromium plating layer successively on the inside surface of said mold thereby converting the chromium plating layer to a chromium carbide layer by reaction with the carbon in the melt sprayed layer. CONSTITUTION:A nickel plating layer 2 is applied on the inside surface of a casting mold body 1, and after a dehydrogenation treatment, a melt sprayed layer 3 of a nickel- base self-fluxing alloy is formed thereon. The layer 3 in this state is formed at a uniform thickness over the entire part or to the thickness increasing successively from the upper to lower part of the casting mold. A chromium plating layer 4 is formed on the top surface of the layer 3 in the same way as mentioned above, whereafter the mold is heated and held heated. The body is thus hardened by precipitation and the layer 2 diffuses into the layer 3 and the body 1 and binds securely with the same. The chromium carbide layer formed on the surface has high adhesion strength and makes the entire coating layer in one body. The chromium carbide layer has high resistance to abrasion at a high temp. region and is virtually free from the seizure with the solidified shell.

Title: Slab type laser element
Inventor: OGAMI HIDEHARU
IPC: H01S3/16
Filed: 1988-04-25
Abstract: PURPOSE:To lead out the S component of a laser beam generated in a laser medium as output and to increase the output by a method wherein the two end surfaces onto or from which a laser beam impinges or is emitted, of the laser medium are respectively covered with each antireflection film against polarized component parallel to the surface onto which the laser beam impinges and a component polarized vertical to this polarization component. CONSTITUTION:A laser beam 1 has totally reflecting surfaces 2 and 2' and two end surfaces 3 and 3', which are slanted to the surfaces 2 and 2' at a certain angle and oppose to each other. The surfaces 3 and 3' are respectively covered with each antireflection film 4 and 4'. The respective reflection factors Rp and Rs of the P component and the S component in the end surface of this element at a time when a laser beam 5 impinged onto the end surface at an incident angle (theta0) are found as a function of the reflection coefficients of the P and S components in the interface between the film 4 and the medium 1. For increasing the ratio of a polarization component, which is utilized for an amplitude of the laser beam, both of the reflection factors Rp and Rs of the P and S components have only to make small and if the antireflection films are formed of a material having refractive indexes to correspond to the incident and emitting angles of the laser beam, both of the Rp and Rs can be made small.

Title: Resin sealed body
Inventor: TSUDA MASUMI
IPC: B29C39/22
Filed: 1985-05-13
Abstract: PURPOSE:To prevent a sealing resin from diffusing without increase in the cost by coating an ink mark in the prescribed thickness on the sealing region peripheral edge of a substrate. CONSTITUTION:An ink mark 5 is formed on the periphery of the sealing region of a sealing region 4 formed to surround an IC module 2. The mark 5 is formed by coating paint for preventing a precoating resin 4 from diffusing in the prescribed thickness in the printing step in case of forming printed wirings on an IC substrate. Thus, it can prevent the sealing resin of the resin 4 from increasing more than required to solder the parts such as resistors near the region. An exclusive step for forming the mark 5 is not necessary.

Abstract: PURPOSE:To improve the durability of a castable refractory containing carbon. CONSTITUTION:The objective castable refractory containing carbon consists essentially of 1-20 pts.wt. carbon and the remainder of one or more selected from alumina, spinel and magnesia. In this castable refractory, 100 pts.wt. refractory aggregate is blended with 0.5-10 pts.wt. light burnt magnesia having surface properties of 5-50mg iodine/g expressed in terms of iodine adsorption and further <=5 pts.wt. glass powder. The oxidation of carbon which is recognized in a conventional material containing alumina cement blended therein is not caused by blending the light burnt magnesia. The glass powder reacts with the light burnt magnesia to improve the structural strength of the refractory by blending the glass powder.

Title: Variable speed fluid coupling
Inventor: KATOU MUNEO
IPC: F16D33/12
Filed: 1982-06-16
Abstract: PURPOSE:To aim at enlarging an adjusting range, by constituting a feed-back pump with the use of a Westco pump so that the axial space thereof is made less for obtaining a compact arrangement, and further by making discharge pressure for feed-back large. CONSTITUTION:Working fluid which enters in an impeller 5 rotates together with the latter for rotating an inner runner 12 so that an output shaft 9 integrally incorporated therewith is rotated. When the rotation of the output shaft 9 is lowered, a spool 21 is pushed up by the actuation of a Wesco Pump 22 and the actuation of a pressure detecting device 28 so that a flow adjusting valve is opened, resulting in increasing the supply volume of working fluid into the impeller 5, and therefore, the rotational speed of the output shaft 9 is raised. On the contrary, when the rotational speed of the output shaft 9 is raised, the spool 21 is moved downward so that the open degree of the flow adjusting valve is reduced for decreasing the inlet flow into the impeller 5, thereby the rotational speed of the output shaft 9 is lowered.

Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of irregularities caused by the scattering of toner and a difference in hue at an edge portion and to always form an image of high quality by executing correction for reducing the quantity of the toner in the edge part of an image, in accordance with the kind of image. SOLUTION: A correction processing image sheet on which the image is formed from a test original image is read, the line widths of the teat original image and a line image formed on the correction processing image sheet and the scattering states of the toner in the vicinities of the test original image and the line image are extracted in each color and a line width correcting part 4 prepares a correction table, based on the obtained information. When an ordinary original image is set, the read image data is stored in an image storage part 7 and it is checked whether the read image is subject to the correction or not. When the read image is subject to the correction, the toner quantity in forming the image is decided by referring to the correction table, to form the image.  Thus, only when the read image is subject to the correction, the line width is corrected to form the image of high quality.
