Title: Pen point of liquid writing utensil
Inventor: FURUSAWA MITSUHIKO
IPC: B43K1/00
Filed: 1990-02-26
Abstract: PURPOSE:To enhance writing life and to improve a writing feeling by externally heating a molded body composed of a crystalline polymer having gaps for the outflow of ink to specific temp. to stretch the same in its axial direction. CONSTITUTION:As a crystalline polymer, a polyacetal resin or a polyamide or polyester resin having a polar group in its molecule is used. For example, the polyacetal resin is melted under heating and subjected to extrusion molding by an extrusion molding machine whose leading end is equipped with a die having a large number of small holes arranged thereto so as to obtain a state having gaps of a profile cross-section after extrusion molding. This molded body is externally heated to 150 deg.C or lower by a heater to be stretched and the stretched one is further shortly cut to obtain a pen point having gaps of a profile cross-section. For example, a pipe 3 is mounted on the outer peripheral part of the pen point 2 wherein the gaps 1 are radially opened to the outer surface thereof in the radius direction if necessary before use.

Title: Deciding method for corrosion rate of metal
Inventor: SATOU TOMOKO
IPC: G01N17/00
Filed: 1981-03-25
Abstract: PURPOSE:To sharply shorten an analysis time required for decision of a corrosion rate, by a method wherein, in a deciding method for metal corrosion rate measured by a coulstat method, a measurement is made on times t1, t2 at a time when a polarization value of a sample metal piece attains given values etan, eta2, and t2-t1. CONSTITUTION:A charge, stored in a capacitor 15 from an opposite pole 13, is momentarily applied to a working electrode 11, consisting of a sample metal piece, by means of a charge applying mechanism 17. A change in potential of the working electrode 11 at a current time is measured as a relation between a polarization value eta and a time t via a reference electrode 12 and in an open circuit state, and it is outputted from an analogue output terminal 20 to record it. Comparators 21 and 22 set polarization values eta1, eta2, respectively, to measure times t1, and t2 at the current time by means of sample hold circuit 24 and 25. Then, an analogue reducer 26 computes t2-t1, and analogue computers 27 and 28 decide a corrosion rate. This causes analysis of eta-t to be simplified widely.

Filed: 1984-03-05
Abstract: PURPOSE:To vary a Fermi level continuously and to improve the run of a photocarrier in a conduction or valence band by varying the impurity density of one layer when two layers which are different in optical band energy, i.e. photoconductive layer and its surface protection layer are joined together. CONSTITUTION:The in-film density of impurity elements in the Vth group of the photoconductive layer 72 is increased near the interface and conduction bands are matched near the interface of the bands while conduction types are controlled properly. Namely, a solid line l indicates P density and a broken line (m) indicates C density in each graph; and the C density is high in the surface protection layer and the P density is shown by a curved line which is maximum near the interface between the surface protection layer and photoconductive layer and decreases toward the substrate side. Consequently, a carrier generated near the interface reaches a free surface smoothly because of the gradients of the conduction band and valence band and there is no remaining potential; and an electrostatic latent image has high resolving power and the deformation of the image is eliminated.
