IPC: F16C33/46
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To improve rolling and sliding properties of a roller on the surface such as the sliding contact surface by providing a macromolecular member into which an extreme-pressure additive is impregnated, on the inner wall of a pocket part of a holder, and by adding this extreme-pressure additive to the surface of a roller, to be extruded into lubricating oil. SOLUTION: A needle roller bearing 21 is composed of a holder 22 of a cylindrical body and a needle roller 10 retained within a pocket part of the holder 22. A small recessed depression part 23 in a diffused state is formed on four inner walls 22D constituting the pocket part. A macromolecular member 24 into which an extreme-pressure additive is impregnated, is embedded within the recessed depression part 23. The extreme-pressure additive attaches directly to the surface of the needle roller 10. A molecular absorption film and a reactive lubrication film can be formed by the extreme-pressure additive on the sliding contact surface of the needle roller 10 to thereby prevent abrasion of the sliding contact surface.

Title: Light-emitting diode array
Inventor: TOMITA SEIZO
IPC: H01L33/60
Filed: 1986-02-17
Abstract: PURPOSE:To prevent the formation of a white line section not sensitized to a photosensitive material under longitudinal feed even when a plurality of array chips are arranged rectilinearly and an LED array is manufactured by filling a clearance shaped between an array chip and an adjacent array chip with an optical reflection material. CONSTITUTION:A clearance 8 formed in a connecting section in an array chip 5 is filled with an optical reflection material having reflectivity the same as or higher than that of a GaAsP crystal layer 3. When luminance does not lower by a chipping 7, etc. in an end- section LED element 6 faced to the clearance between the chips, the amount of light does not vary by the connecting section by using filters, the amount of reflected light B therefrom in the clearance with an adjacent array chip 5 is equal to reflected light A from the GaAsP crystal layer 3 between other LED elements 4. When luminance lowers by the chipping 7, etc. in the end-section LED element 6 faces to the clearance between the chips, fillers having large reflectivity compensating the deterioration of luminance are used. When the fillers 9 are affected by the thermal expansion of the array chip 5, a pigment, etc. for conforming the amount of reflected light are mixed with an elastic substance such as a rubber and employed. Accordingly, even when a plurality of the array chips 5 are disposed rectilinearly and an LED array is manufactured, a white line section not sensitized to a photosensitive material under longitudinal feed is not shaped.

Abstract: PURPOSE:To eliminate an adjacent disturbance signal from an adjacent channel of a reception broadcast station by shifting the frequency of an intermediate frequency signal and shifting the frequency of an operating point of a PLL detection circuit simultaneously. CONSTITUTION:When an adjacent disturbance signal exists in the vicinity of a desired broadcast frequency, an adjacent disturbance signal detection circuit 4 detects an adjacent disturbance signal to output a corresponding offset voltage and to shift the oscillated frequency of 1st and 2nd VCO circuits 5, 6.

Moreover, the operating point of a PLL detection circuit 7 is at the frequency of 11.7MHz+DELTAf and FM detection is applied to a desired broadcast frequency without any problem.
