    • A nonwoven fabric is constructed of a highly flat glass fiber which is a glass fiber whose section is flat and has a flatness ratio of 2.0 to 10 and which has such a section that the packing fraction is at least 85%, preferably at least 90%. In this nonwoven fabric, the glass fiber section has a shape near rectangle, and hence, the glass fibers can be arranged very densely to form a thin nonwoven fabric having a high bulk density, and when it is used as a laminate material, the glass fiber content can be increased and the surface smoothness can simultaneously be enhanced and can be used appropriately as a reinforcing material for a printed wiring board. Moreover, the above flat glass fiber can be produced by use of, for example, a nozzle having such a shape that one side of the major axis walls of a nozzle chip having a flat nozzle hole is partly notched.

    • A valve opening and closing timing control apparatus is disclosed, which includes an engine including a cam shaft and a crank shaft, a first sensor adapted for detecting rotary positions of the cam shaft, a second sensor adapted for detecting rotary positions of the crank shaft, a hydraulic pump driven by the crank shaft, a rotary phase varying means disposed on the cam shaft and adapted for varying rotary phases of the cam shaft, a hydraulic line connecting the hydraulic pump and the rotary phase varying means, a hydraulic control means disposed in the hydraulic line, an electronic control means adapted for controlling the hydraulic means and receiving output signals which are output by the first sensor and the second sensor at least, thereby operating the rotary phase varying means with the hydraulic control means under linear control. The electronic control means detects the rotary positions of the cam shaft and the crank shaft and operates the rotary phase varying means with the hydraulic control means under the linear control in order to establish an optimum valve opening and closing timing depending on engine conditions. Hence, the valve opening and closing timing control apparatus can establish the valve opening and closing timing at optimum and desired occasions, which distinguishes over the conventional digitized valve opening and closing timing.
