Title: Manufacture of metal matrix composite
Inventor: KUBO MASAHIRO
IPC: C22C47/08
Filed: 1988-10-06
Abstract: PURPOSE:To inexpensively and efficiently manufacture a reinforcement-filled metal matrix composite by introducing a formed body of reinforcement into a molten matrix metal, such as Al and Mg, through a layer of molten metal oxides including B2O3 formed on the surface of the above molten matrix metal. CONSTITUTION:Molten metal oxides including at least B2O3 are disposed into a state of layer on the surface of a molten matrix metal, such as Al, Mg, Al alloy, and Mg alloy. Subsequently, a formed body of reinforcement is introduced through the above layer of molten metal oxides into the above molten metal. This formed body can be prepared by forming a reinforcement, such as Al2O3 short fiber, into the prescribed shape. By the above procedure, the wettability of the molten metal to the reinforcement is improved, and the molten metal can be thoroughly infiltrated into the whole of the formed body without requiring the pressurization of the molten metal, the heating of the formed body at high temp., etc. Then, the molten metal infiltrated into the formed body of reinforcement is solidified, by which the metal matrix composite of the prescribed shape in which the matrix metal is filled into the reinforcement can be obtained.

Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain enough contrast potential at any developing area to clearly record two kinds of visualized image by setting a background area potential from both points of normal developing and reverse developing. SOLUTION: Correction based on a reverse developing area is performed in the first rotation of a photoreceptor 1; and the photoreceptor 1 is electrified, a second reference light pattern is produced by an exposure signal source 6, an exposure device 7 irradiates the photoreceptor 1, and a latent image constituted of a normal developing area and the background area is formed on the photoreceptor 1 in the second rotation of the photoreceptor 1.

Title: Printed-circuit board
Inventor: UEJIMA TAKAHITO
IPC: H05K1/02
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To prevent a drop in the connection reliability of boardto-board connectors due to a situation that a scattered flux is stuck by a configuration wherein separate printed-circuit boards of different kinds are fitted back, by a push back method, to separate printed-circuit boards on which the board-to- board connectors are mounted and a gap between the separate printed-circuit boards is eliminated. SOLUTION: Separate printed-circuit boards 5b, of different kinds, which are connected to separate printed-circuit boards 5a on which board-to-board connectors 1 are mounted are fitted back by a push back method. Since the separate printed-circuit boards 5b are fitted to an aggregate printed-circuit board body so as to be connected to become one board, a gap does not exist between themselves and the separate printed-circuit boards 5a. Thereby, when a flux is coated in a manufacturing operation for an electronic control apparatus, it is possible to prevent the flux from being scattered to connection terminals at the board-to-board connectors 1. Consequently, it is possible to prevent a drop in the connection reliability of the connectors 1 due to a situation that the flux is stuck to the connection terminals.

IPC: C08J9/14
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To obtain a foamed resin sheet which exhibits a beautiful light interference phenomenon caused by cell membranes contained therein and hence shows a keen color rich in variability by causing cells of which the lengths are in a specified range to be present and distributed in a polyolefin resin sheet. SOLUTION: Cells having lengths of 1-10 mm are caused to be present and distributed in a polyolefin resin sheet. This foamed sheet shows a keen color caused by the interference of light passing through cell membranes constituting cells or by the interference of light reflected by the cell membranes. The polyolefin resin includes polybutylene, polyisobutylene, etc., in addition to polyethylene and polypropylene, a relatively low-density polyethylene resin being preferable. This foamed sheet has a light transmission represented by a haze value of 40% or lower. The color rendition effect of this foamed sheet is enhanced by compounding a suitable light color pigment when the polyolefin resin is molded by foam extrusion.

IPC: G01N21/23
Filed: 1988-10-08
Abstract: PURPOSE:To easily measure birefringence characteristics by searching for a couple of the closest values among values of retardation calculated by using results obtained by measuring the relation between the angle of rotation when the coupled body of a sample, a polarizer, and an analyzer is rotated and the intensity of light transmitted through the three bodies as to >=3 different- wavelength light beams.

Then the relation between the angle of rotation when the coupled body of the sample 4, polarizer 3, and analyzer 5 is rotated relatively and the intensity of the light transmitted through the polarizer 3, sample 4, and analyzer 5 is measured as to >=3 light beams. A couple of the closest values are found in a sequence of retardation values by wavelengths calculated by using the measurement result as to the respective wavelength light beams to determine the retardation values by the wavelengths. Consequently, one couple of values can be determined unequivocally among he many calculated retardation values to determine the wavelength characteristics of birefringence.

Title: Driving system for solid-state image pickup element
Inventor: EGAWA YOSHITAKA
IPC: H04N5/341
Filed: 1989-09-30
Abstract: PURPOSE:To enable electronic zooming by using a solid-state image pickup element forming multiple picture elements by transferring a charge accumulated in a first charge transfer element for the picture element less than the plural picture elements corresponding to a ratio between a length for the whole row of a photoelectric converting device and a length for a whole continuous column, accumulating the charge in a second charge transfer element and afterwards, successively transferring the charge in a row direction. CONSTITUTION:At the time of high resolution or an enlarged mode, the number of the picture elements to read the signal charge of a vertical transfer part to a horizontal transfer part with an enlarged area as the center of the element during the blanking period of a video signal is reduced rather than that of a standard mode. At such a time, the signal charges before and behind the enlarged area not to be transferred during the vertical effective period of the video signal are read out during the vertical blanking period while overlapping the preceding and following charges by a high-speed transfer pulse. For reading out the signal charge of the horizontal transfer part, the signal charge with the picture elements, which number is less than that of the standard mode, is detected by a signal charge detection part. At such a time, the signal charges before and behind the enlarged area not to be transferred during a horizontal effective period are read out by impressing a speedy horizontal transfer pulse during the horizontal blanking period while overlapping the preceding and following charges. Thus, in the solid-state image pickup element, electronic zooming can be executed with high function.
