Title: Preparation of base material for forming fluororesin film
Inventor: TAGUCHI KIYOUHEI
IPC: B05D7/24
Filed: 1989-06-22
Abstract: PURPOSE:To form a fluororesin film of stable quality by applying etching to the surface of a base material formed from an aluminum alloy containing 1 - 20wt.% of silicon up to a predetermined depth and allowing silicon particles to protrude from the surface of the matrix phase to roughen the surface of the base material. CONSTITUTION:Since hard silicon particles 2 of primary crystals are scattered in an aluminum alloy, the surface hardness of the alloy increases and, when a fluororesin film 4 is formed to the surface of the alloy, abrasion resistance is enhanced. When the surface of the fluororesin film formed into a rough surface is rubbed, the fluororesin filling the gaps between protruding silicon particles is not shaven off and the characteristics such as non-stickiness or the like possessed by the fluororesin are not damaged. However, when the content of silicon is below 1wt.%, these effects are not obtained and, when exceeds 20wt.%, processibility becomes bad. When chemical or electrochemical etching is applied, silicon particles 2 protrude from the surface of matrix phase 3 to roughen the surface of a base material 1 and the excellent close adhesiveness is obtained between the fluororesin film 4 and the base material 1.

Title: Color image forming device
Inventor: UCHIYAMA AKIHIKO
IPC: B41J2/525
Filed: 1993-06-30
Abstract: PURPOSE:To minimize the damage of the surface of an image carrier in a cleaning process by removing toner images on the surface of the image carrier altogether, after the detection of a density by each toner is completed, in image density control. CONSTITUTION:When a concn. control action is taken, an image signal for a patch for detecting the concn. is generated by a pattern generating circuit 23, to form latent images for plural patches on a photosensitive drum 1 in response to the signal. These latent images are developed with each toner of yellow, magenta, cyan and black by developing units 4a-4d. In such a case, normally, when the control of the concn. of the yellow toner of the first color is completed, a process for cleaning the toner image on the transfer drum is started, but in the above-mentioned process, immediately, the concn. of the magenta toner of the second color is controlled without the cleaning process. Thus, when the control of the toner concentrations of four colors is completed, the toner images of four colors on the transfer drum 5 are transferred on the photosensitive drum 1. The toner images transferred on the photosensitive drum 1 are cleaned by a cleaning unit 6.

Title: Identification method of metal
Inventor: YAMADA KEITA
IPC: G01N9/36
Filed: 1982-09-16
Abstract: PURPOSE:To identify that the metallic piece to be tested is prescribed metal only when the absolute values of the difference in specific gravity and the differences in the thickness of various parts are all within the prescribed numerical values with the prescribed metal and the metal to be tested by performing the measurement of specific gravity with a specific gravity measurement device and the simultaneously measurement of thickness with both thickness gauges combined with an ultrasonic thickness gauge and a digital thickness gauge. CONSTITUTION:A computer 11 calculates and displays specific gravity rho=-M/F by using the weight M and buoyancy F of a metallic piece measured with a specific gravity measurement device and judges whether the difference rho''=rho'-rho from the specific gravity rho' of the prescribed metal stored previously in the computer 11 is within the specified numerical value or not. A metallic piece 4 is placed on a transducer 23a in a water tank, and a rotary ring 21d of a digital thickness gauge is brought into contact with the upper part of the piece 4. The thickness TG by the digital thickness gauge and the thickness TS by an ultrasonic thickness gauge are read into the computer 11 which displays the thickness difference t=TG-TS by both measurements and judges whether the (t) is within the thickness difference (specified numerical value) stored previously in the computer 11 or not. The computer displays that the metallic piece is the prescribed metal if both of the difference rho'' in the specific gravity and the difference (t) in the thickness are within the specified numerical values.

Title: Manufacture of chromium steel
Inventor: ICHIHASHI HIROYUKI
IPC: C21C1/02
Filed: 1978-12-28
Abstract: PURPOSE:To reduce Cr2O3 sufficiently and to conduct decarburization smoothly without being restrained with slag, by addn. of Cr ore into molten steel during blowing of molten cast iron, having been dephosphorized by use of O2 gas and slag making material for dephosphorization, in a converter without use of slag making material. CONSTITUTION:During blowing of molten steel, which has been dephosphorized by use of O2 gas and slag making material for dephosphorization, Cr ore such as Cr2O3 is added to the molten steel so that Cr2O3 is reduced according to the following equation; Cr2O3+3C=3CO+2Cr. Hereby metallic Cr is formed and is dissolved into the molten steel to form high chromium steel. Use of inexpensive Cr ore accompanied by FeO or Al2O3 is also effective because these materials work as cooling materials. Because no slag making material is used, the slag is composed of nearly Si, Mn and Fe only, in addn., because fairly amount of Si, Mn are previously removed, only a small quantity of slag composed of mainly iron oxide is formed, consequently decarburization is conducted smoothly without being restrained by the  slag.

Title: Manufacture of laminated type varistor
Inventor: TAIRA HIROAKI
IPC: H01C7/10
Filed: 1988-06-29
Abstract: PURPOSE:To avoid defective connection positively by intruding an external electrode to the internal electrode side and compensating shrinkage even when an internal electrode is shrunk at the time of baking by forming the external electrode to the laminate of a varistor layer and the internal electrode and integrally sintering the whole. CONSTITUTION:Varistor layers 2 and internal electrodes 3 are superposed alternately, and laminated so that one end faces 3a of each internal electrode 3 are exposed interchangeably to both end faces of the varistor layers 2, ceramic layers 7 as dummies are stacked onto the upper and lower surfaces of the laminate, and the whole is pressed and contact-bonded by a press, thus shaping the laminate 4. Both side faces 4a, 4b from which the internal electrodes 3 of the laminate 4 are exposed are coated with paste, which mainly comprises Ag and to which Pd is added, and external electrodes 5 are formed. The laminate 4 is heated and baked within a range of 850-1300 deg.C in air. Since the internal electrodes 3 have a shrinkage factor larger then the varistor layers 2 at that time, one end faces 3a of the internal electrodes 3 intend to be shrunk and pulled in, but the external electrodes 5 follow up to the movement of one end faces 3a and intrude to the insides, thus preventing the generation of clearances.
