IPC: D01D5/24
Filed: 1995-03-20
Abstract: PURPOSE: To prepare a polypropylene hollow yarn membrane having high fractionation characteristics and high water permeation performance without forming a sealed hole by producing hollow yarn which has pore diameter equivalent to half the whole pore volume in the integral curve of pore diameter measured by a mercury porosimeter, the half value width of a pore diameter partial distribution curve and a vacancy rate respectively as specified values. CONSTITUTION: Polypropylene having >=97% tacticity and <=15 melt index value is melted and shaped. Unstretched yarn having the multilayer structure of a stacked lamella grown in a high degree is stretched and pore-opening is performed in the prescribed conditions. Thereby, such a hollow yarn membrane is obtained as pore diameter ϕ0 of 50% of the whole pore volume is 1-10μm in the integral distribution curve of pore diameter measured by a mercury porosimeter. The half value width Wh of a pore diameter differential distribution curve obtained by differentiating the integral distribution curve of pore diameter satisfies Wh/ϕ0 <=0.5 and a vacancy rate is 70-95%. In the hollow yarn membrane, pore diameter distribution is extremely narrow and the vacancy rate is high and the blockade of pore is difficult to be caused even if the hollow yarn membrane is made hydrophilic.

Abstract: PURPOSE:To obtain a large quantity of magnetic recording media which assure sufficient S/N in a very short wavelength range by forming polyester film as a film, introducing the film continuously into a vacuum and forming a magnetic recording layer thereon by a vacuum deposition method. CONSTITUTION:A vacuum vessel 10 is divided to an upper chamber 11, a lower chamber 12 and an irradiation chamber of a charge beam 23. An endless belt 14 is so disposed as to turn between the atm. side and the inside of the vacuum vessel. A high-polymer film 15 is extruded and stretched by a film making device 16. After the polyester film 15 is stretched, the film is continuously introduced into the vacuum and the magnetic recording layer is formed thereon by the vacuum deposition method. The microscopical fluctuation in magnetic characteristics by adsorbed water is, therefore, decreased to a negligible level. Noises are effectively decreased in the very short wavelength range. The signal drop-outs induced by the irregularity when the coated film of a water-soluble high polymer is transferred to the material are minimized as well. The magnetic recording medium having the excellent S/N in the short wavelength recording and the good uniformity is thereby obtd. at a high speed.

Title: Image forming device
Inventor: KUMON TOSHIHIKO
IPC: G03G21/00
Filed: 1988-04-06
Abstract: PURPOSE:To reduce the size and cost of the device by detecting whether or not there is a photosensitive body with the output signal of a density sensor when no image is formed on the photosensitive body. CONSTITUTION:This device is equipped with the detachable photosensitive body 1 and the density sensor 53 which detects the density of a toner image formed on the photosensitive body, and the density sensor 53 is, for example, a reflection type photoelectric sensor and arranged facing the surface of the photosensitive body 1. The density sensor 53 photodetects reflected light corresponding to the density of the toner image formed on the surface of the photosensitive body and when the photosensitive body is absent, there is no reflected light and any output signal is not generated. Consequently, a photosensitive body detecting means (CPU) compares the level of the output signal of the density sensor 53 with a reference level when the sensor 53 is not used for the density detection, thereby detecting whether or not there is the photosensitive body 1 according to which level is larger. Consequently, the density sensor 53 can be used in common to detect whether or not there is the photosensitive body, and the device is reduced in size and cost.
