Title: Production of chrome plated steel sheet having excellent adhesiveness to paint
Inventor: KASHIWADA KOUSUKE
IPC: C25D11/38
Filed: 1985-04-27
Abstract: PURPOSE:To produce a chrome plated steel sheet having excellent adhesiveness to a paint by executing an anodic treatment in succession of a cathodic treatment under specific conditions in a dip washing stage which is an intermediate stage between a plater part and a chemical part. CONSTITUTION:The steel sheet is subjected to the cathodic electrolytic treatment in an aq. soln. (plater part) consisting essentially of a chromic anhydride to deposit mainly metallic chromium. The steel sheet is then subjected to the cathodic treatment at 5-20A/dm<2> current density and >=1C/dm<2> current conduction rate to make uniform the ununiform chromium oxide film on the surface of the steel sheet in the dip washing stage (drag out) in which 20-100g/l chromic anhydride is made to exist. The steel sheet is further subjected to the anodic treatment at 2-10A/dm<2> current density and 0.2-5C/dm<2> current conduction rate in the same bath to uniformly dissolve away the chromium oxide film. The chromium oxide film is thereafter deposited thereon by the cathodic electrolytic treatment in an electrolyte (chemical part) in which 20-200g/l chromic anhydride and 0.05-3g/l material such as ammonium fluoride and sodium fluoride for forming F<-> ions in terms of fluorine are made to exist.

IPC: B60Q1/115
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To perform the optimum illumination on a traveling road for a vehicle by a method wherein a head lamp regulation setting is adapted to the road condition and situation obtained based on the sensor signal. SOLUTION: When a vehicle travels toward a curve on a self-traveling road, the traveling road is demarcated by the stripe-shaped center line and the edge marking. The video image detected by a video sensor 2 contains the information that the vehicle is moving toward the left curve. The information picked up by the video sensor is evaluated by an image evaluation unit 14, and the parameter obtained thereby is transmitted to a control device 15, and transmitted to a head lamp 9 therefrom. A left head lamp of a vehicle is deviated to the left in the horizontal direction to clarify that a right head lamp is adapted to the condition and situation of the traveling road on the curve not only in the left direction but also in the upwardly perpendicular light direction.

Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to correct the luminance level of the incident side end of a light guiding plate and to lessen unequal brightness by forming light diffusion regions for irregularly reflecting illuminate light on the flanks and end face sides of a planar member. SOLUTION: A light scattering light guiding body 10 is formed by uniformly incorporating and dispersing translucent particulates varying in the refractive index from the refractive index of a matrix consisting of polymethyl methacrylate into this matrix and forming the matrix into a wedge shape in section. As a result, this light scattering light guiding body 10 emits the component below the critical angle to an exit surface from the exit surface while repetitively reflecting and propagating the illumination light entering from the incident surface 11 between the exit surface and a slope. The incident surface 11 of the light scattering light transmission body 10 is formed on a matte surface (embossed surface) by a matte surface treatment so as to have a light scattering function.  As a result, the incident surface 11 of the light scattering light guiding body 10 is formed as a rough surface to make up the exit light quantity insufficient on the incident surface 11 side and to lessen the unequal brightness which occurs in parallel with the incident surface 11.

Abstract: PURPOSE:To reduce the number of steps of a program processing, by inputting the vacant output of the transmission data buffer of a device for serial data communication to an input terminal to take synchronism with the external device of a CPU via an inversion circuit. CONSTITUTION:The program of the CPU 1 inserts an instruction to check the input terminal 5 before writing transmission data on the transmission buffer of the device 2 for serial data communication. When the instruction is executed by the CPU 1, the instruction to write the transmission data of the next instruction on the transmission buffer is executed if the input terminal 5 is set at an L level, that is, the output terminal 4 of the transmission buffer is set at an H level, and a state is returned to an original state. When the data is written on the transmission buffer, the transmission buffer vacant output terminal 4 goes to the L level, and the input terminal 5 to take the synchronism with the external device goes to the H level. Therefore, the CPU 1 checks the input terminal 5 at every specific time, and repeats checking until the input terminal 5 goes to the L level.

Abstract: PROBLEM TO BE SOLVED: To provide outstanding crystallization property for a battery and improve its charging/discharging cycle characteristic, by specifying the amount of added cobalt in lithium-nickel complex oxide of positive electrode active material, forming a hexagonal system, and also limiting the space occupying factor of metallic ions except lithium ion in a 3a site. SOLUTION: Positive electrode active material for a secondary battery is represented by chemical formula LiCox Ni1-x O2 . Amount x of added Co is 0<x<=0.2 and it has a hexagonal system. The space occupying factor of metallic ions except lithium ion Li<+> in a 3a site, which is provided from results of the Rietveld analysis by X-ray diffraction, is less than 2%. The space occupying factor of metallic ions is usually the sum of the space occupying factors of nickel ion and cobalt ion. In the electrode which uses this positive-electrode active material, the irreversible capacity is decreased due to its outstanding stoichiometric composition. Using the positive electrode active material can increase discharging capacity and coulomb efficiency of a secondary battery.
