Title: Porous plastic filter
Inventor: EGAWA YOSUKE
IPC: B01D39/16
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To secure the strength of a porous plastic filter enough to endure a long use, by specifying the bulk density and the angle of repose of particles respectively in a porous plastic filter obtained by sintering and forming the particles of a thermoplastic material. SOLUTION: In the porous plastic filter obtained by sintering and forming the particles of a thermoplastic material, it is obtained by sintering and forming the particles of 0.40-0.55 g/cm3 bulk density and of 25-40 deg. angle of repose. The particles are preferably an ultrahigh molecular weight polyethylene. The plastic material is not limited to a specific material as long as it is a thermoplastic resin such as polyethylene, polypropylene and polyvinyl chloride giving a porous material by sintering. However, the ultrahigh molecular weight polyethylene is preferred, in consideration of fluidity and a melting property in the course of sintering forming, and of the using and the environmental conditions such as separating and removing, easily, the fine particles sticking on the surface of the filter.

IPC: F04B37/08
Filed: 1986-07-02
Abstract: PURPOSE:To eliminate a large scale regeneration facility, by operating a compressor and stopping reciprocation of a displacer then passing a normal temperature high pressure operating gas continuously into a cylinder. CONSTITUTION:When a cryo-pump is regenerated, a second expansion space 5 in a cylinder 1 and a low pressure line 11 in the downstream of a valve 10 are coupled through a piping 20. Then a compressor is operated while simultaneously reciprocation of a displacer 2 is stopped so as to feed a normal temperature high pressure operating gas in a high pressure line 9 continuously into a buffer space 3 in the cylinder 1. Consequently, quick regeneration can be realized without employing a conventional large scale regeneration facility.

Abstract: PURPOSE:To reduce a contact resistance and to prevent lower layer interconnection from disconnecting by opening a contact window larger than the contact of upper and lower conductive layers, and forming tungsten films on the upper surface and sidewall of the lower conductive layer in the window. CONSTITUTION:An insulating film 2 is formed on a conductive film 3 of a lower layer formed on a semiconductor substrate 1. After a contact window 6 larger than the contact of the lower layer conductive layer 3 with an upper layer conductive layer 8 is opened at the film 2, tungsten films 7 are vapor grown on the upper surface and sidewall of the layer 3 exposed in the window 6, and the film 8 is further formed through the film 7. Accordingly, the contact area of the layer 3 with the film 8 is increased, and the layer 7 in the window 8 becomes an etching mask of the layer 3 at the time of dry etching for forming the layer 8. Thus, a contact resistance is largely reduced to prevent lower layer Al interconnection 3 from disconnecting.

Abstract: PURPOSE: To erase multiple echoes by using an integer-fold round trip delay time as the delay time of multiple far-end echoes.  
     CONSTITUTION: With respect to a near-end echo, a false near-end echo signal is generated from a transmission signal by a near-end echo canceller 1. With respect to first, second,... n-th far-end echoes, the transmission signal is successively delayed in delay circuits 3 1 ∼3 n , which wave the round trip delay time preliminarily obtained by training sequence, by integer-fold delay times and is given to far-end echo cancellers 2 1 ∼2 n . Each far-end echo canceller generates a corresponding false far-end echo from the delayed transmission signal, and this generated echo and the false near-end echo signal are added to a false echo signal. Such a signal is subtracted from the reception signal to erase not only the near-end echo but also multiple echoes based on various far-end echoes.
