Filed: 1992-09-22
Abstract: PURPOSE:To provide a mercury carrier which can control impurity gas emitted out of pellets, and can keep the amount of mercury impregnation highly accurate, as well as to provide a mercury vapor filled discharge lamp employing the aforesaid carrier. CONSTITUTION:A mercury carrier and a mercury vapor filled discharge lamp using this mercury carrier are provided wherein each inorganic porous pellet 81 having continuous holes 82 is impregnated with liquid mercury, and in the pellet 81 the average opening diameter (do) of the continuous holes is made smaller than an average hole diameter (d1). In the inorganic porous pellets, since the average opening diameter (do) of the continuous holes is made smaller than the average cavity hole (d1), a specific surface becomes small, and impurity is thereby emitted less. In addition, since each opening section is slenderer than the inside of each hole, mercury impregnated inside is prevented from unguardedly flowing out and evaporating, so that the amount of contained liquid mercury can be kept highly accurate.

Abstract: PROBLEM TO BE SOLVED: To maintain a smooth motion of valve driving system which retains a shim, swingable in accordance with the cam profile of three dimensional cam, by reduction of friction coefficient enabled by forming the radius of curvature of sliding surface of shim bigger than that of guide groove fixed to the valve lifter. SOLUTION: At low speed rotation of internal combustion engine, cam shaft shifts leftwards and cam profile for slow speed rotation at the right side of three dimensional cam 1a contacts with flat surface of shim 2 consequentially, and cam nose 1c pushes shim 2 which swings in a small angle in accordance with the rotation of cam 1a synchronously, and valve 5 opens and stubs through valve lifter 4 in small working angle and lifting distance of the valve accordingly. In this case, oil is supplied adequately to the space between the sliding surface of shim 2a and guide groove 3a by forming the radius of curvature of sliding surface 2a, facing parallel to the direction of cam shaft, bigger than that of guide groove 3a facing to the same direction. Thus, frictional force arisen from the swing of shim 2 is reduced and smooth motion is maintained.

Abstract: PROBLEM TO BE SOLVED: To automatically set the frequency and phase of a sampling clock signal at an optimum value even when image signals (PC image signals) varying in specifications are inputted by respectively specifying the frequencies and phases of the signals of the sampling clock signals. SOLUTION: A control section 16 sets the frequency dividing ratio (n) of a frequency dividing circuit 18 and the phase ϕ of a phase correction circuit 19 and supplies both to the respective circuits 18, 19.

The input signals are formed as static image signals and the frequency dividing ratio (n), i.e., frequency fs and phase ϕ of the sampling clock signal are changed in such a manner. The number of the change points of the digital signals after A/D conversion is then counted and the frequency and phase at which the count value is saturated to the max. value are retrieved. The frequency fs and phase ϕ of the sampling clock signal CLS are thus determined.
