Title: Production of hollow fiber for wavelength conversion element
IPC: G02B6/02
Filed: 1992-03-13
Abstract: PURPOSE:To obtain a uniform core free from cracking and to lessen the loss of the basic wave propagating therein by heating and stretching a glass tube in the presence of an active or inert gas, thereby producing the hollow fiber for a wavelength conversion element. CONSTITUTION:The glass tube T is stretched under heating, by which the hollow fiber F for the wavelength conversion element is produced. For example, an annular heater H is sued for stretching the glass tube T. In order to heat the glass tube T evenly from the circumference by the heater H, the glass tube T is fixed in the state of aligning the heater and the center line. The glass tube T is stretched and the hollow fiber F for the wavelength conversion element is formed when the glass tube is gradually pulled downward while the tube is evenly heated from the circumference by the heater H. The execution of the stretching in the presence of the active or inert gas and the treatment of the inside wall surface of the hollow fiber F by this gas are enabled simply by passing the gas in the glass tube T or substituting the inside of the glass tube T with the gas.

Title: Ghost eliminating device

IPC: H04N5/21
Filed: 1981-04-16
Abstract: PURPOSE:To improve the qualization effect and the equalization speed in the MAE method, by setting a large correction quantity first and reducing the correction quantity stepwise in accordance with the elapse of time to perform equalization. CONSTITUTION:When a vertical synchronizing signa without ghost is used as a reference signal R(t), the number of times of equalization is measured by counting a vertical synchronizing signal, which is generated by a vertical synchronizing signal extracting circuit 917, in a counter 915. If the counter 915 is so controlled that a positive output is generated for a count value equal to or smaller than a value corresponding to the number of times of equalization and a negativ output is generated for a count value larger than the value corresponding to the number of times of equalization, outputs of an integrator 911 and etc. correspond to the correction quantity of a tap gain, and the amplification degree is increased when the number of times of equalization is small and the output of the counter 915 is positive, and the amplification degree is reduced when the number of times of equalization becomes large and the output of the counter 915 is negative. Consequently, the equalization effect and the equalization speed in the MAE method are improved.
