Title: Knob type propelling pencil
Inventor: HASHIMOTO YASUYUKI
IPC: B43K21/16
Filed: 1989-06-08
Abstract: PURPOSE:To reduce the number of parts and to facilitate manufacturing and assembling by operating a feed direction converting means by the bending of a flexible connection means to convert a predetermined quantity of displacement in a radius direction to the motion of a lead gripping mechanism in the axial direction thereof to feed out a lead by a predetermined length. CONSTITUTION:When a lead 25 is abraded by writing, a plurality of the places or one place of the outer periphery of a rubber cover 17 are pressed by the bulb of a finger. The rubber cover 17 and a press member 10 are pressed in the radius direction to be reduced in their diameters. By this method, a clamp receiver 5 and rear shaft 3 approaches each other so that the interval therebetween becomes a distance (l) at the max. The clamp receiver 5 is fixed and the chuck 1 integrated with the rear shaft 3 advances while compresses a chuck spring 14 through a small diameter part 2. Since a distance l+alpha is provided in an annular groove 16, the other press member 10 not pressed by a finger freely moves through this part and, since said member 10 is also free between adjacent flexible connection members, the bending of the pushed press member 10 is not obstructed by the not-pushed press member 10. This operation is the same to the knocking operation of a usual propelling pencil and the lead 25 can be allowed to protrude from a point opening 20.

Title: Wiring structure of semiconductor integrated circuit and forming method
Inventor: TAKAHASHI SOJI
IPC: H01L23/52
Filed: 1996-06-06
Abstract: PROBLEM TO BE SOLVED: To not allow increase of propagation delay and wiring density and reduce crosstalk noise by covering the rear surface of the wiring provided on a semiconductor integrated circuit with a conductive material having a higher permeability. SOLUTION: The rear surface of wiring 1 provided on a semiconductor integrated circuit is covered with a conductive layer 2 having high permeability. That is, after a wiring 1 is formed, entire part of wiring 1 is covered with a film 2 having higher permeability and the film 2 having high permeability is left at the side surface of the wiring 1 by the dry etching method. Thereby, a wiring structure of which side surface is covered with the conductive film 2 having high permeability can be formed. It is enough to use a CVD(chemical vapor deposition) or a sputtering method to cover the entire part of the wiring 1 with the high permeability film 2. The high permeability film 2 for the covering purpose is formed a little thicker than the target thickness, estimating some reduction of the side surface by the dry etching as the post process. As a high permeability film 2, Permalloy is used.

Title: Method and apparatus for manufacturing laminated material
Inventor: HORIKAWA MITSUMASA
IPC: B27J1/00
Filed: 1993-06-16
Abstract: PURPOSE:To reduce a manufacturing man-hour and to reduce a manufacturing cost by using stems of gramineous plants such as kaoliang stems, etc., to be semipermanently supplied and using the stems of the grasses as they are or them by rolling. CONSTITUTION:Since flat stems 3 are, after cracks are generated in a fiber direction by collapsing means, dipped in thermosetting resin liquid (r), the stems 3 are effectively impregnated with the liquid (r). Since dry stems 6 are sutured in an aligned state before laminating, bundled to a sheetlike matter 8, it is easily handled at the time of laminating to improve operability. Even if diameters of the stems 3 for constituting the matter 8 are irregular to cause uneven surface to be formed on the matter 8, the stems 6 are spaced at an interval. Thus, when they are brought into pressure contact and superposed with the matter 8 or when the matter 8 is again pressed to be collapsed to coat its surface with adhesive, the dry stems are spread in gaps provided between the stems 6 to prevent waviness.
