Title: Hand-phone operating device
Inventor: PARK WANG SIK
IPC: H04B1/38
Filed: 2000-06-21
Abstract: Bearing shells are inserted into the connecting-rod eyes of connecting rods used in internal combustion engines. The fitting of bearing shells constitutes a production step which is a potential source of defects. The aim of the new method is to create connecting rod bearings which require less assembly work and are firmly joined to the bearing metal. According to the invention the large connecting-rod eye (3) is subjected to pre- spindle trimming, cracking and further spindle trimming to the coating tolerance, sandblasted and microporously plasma-coated with an aluminium bronze. At the start of plasma spraying the plasma layer is deposited at a high temperature, which results in good adhesion of the plasma layer to the material of the connecting-rod eye and low porosity of the plasma layer. To prevent annealing of the material of the connecting-rod eye the deposit temperature of the plasma layer is lowered for that area which is removed by subsequent working of said plasma layer. After plasma coating the connecting-rod eye is opened by removing the bearing cap (9), which ruptures the plasma layer (16). The cap (9) is then screwed back on and the actual sliding layer created by fine spindle trimming. To improve the oil retention volume the plasma layer (16) has an annular groove (32). The invention is used in internal combustion engines.

Abstract: PURPOSE: A switch control apparatus of an SMPS(Switch Mode Power Supply) is provided, which does not need a pin for an external device and enables a soft start without using an external capacitor. CONSTITUTION: If an oscillation part(10) outputs a clock pulse of a constant period continuously, the first single pulse generation part(20) generates an output pulse making a high state for a constant time after a clock pulse is fallen from a high state to a low state by receiving the clock pulse. That is, the single pulse generation part outputs a high state signal only during a specific period and outputs a low state signal at other periods. A comparison part(30) includes a comparator comparing a comparison voltage with the first voltage. A signal from the comparison part is inputted to a reset part(40), and is inputted to the second single pulse generation part(50), and when an output of the second single pulse generation part satisfies an output of an output part(60), it operates the reset part to initialize an input of the comparison part. A level of a turn-on voltage of the SMPS from the output part increases slowly, and therefore a switch of the SMPS makes a soft start.
