Title: Ring for brazing
Inventor: MIMURA HISAO
IPC: B23K1/18
Filed: 1994-06-02
Abstract: PURPOSE:To enable satisfactory brazing and to facilitate automation assembling. CONSTITUTION:In a ring 10 which is assembled in a joined member and used for brazing, the tip ends of a plate like brazing filler metal are faced to each other without superposing them, and made them into a ring shape with an inside diameter almost identical with or slightly larger than the outside diameter of the joined member. The ring is provided, along the longitudinal direction, with the same cross-sectional shape in the direction vertical to the longitudinal direction; therefore, in the case where the ring 10 is assembled into the joined member, heated and melted, the build-up quantity of a cladding that is formed around the axis of the joined member through boundary tension is uniformized for each part around the axis. Further, when the ring 10 is placed on a flat surface so that one end face is brought into contact with the surface, the center axis and this flat surface are at right angles to each other, and the ring 10 is easily raised by a simple automatic assembling device equipped with a lot material and the like.

Title: Tape delivery mechanism for tape delivery cutting device
Inventor: SHIGETA KATSUMI
IPC: B65H20/04
Filed: 1988-05-18
Abstract: PURPOSE:To make several types of tapes different in stiffness each deliverable in an accurate manner by making energizing force by an energizing means, energizing a driven roller to the side of a driving roller, and that of a pressing stay by a coil spring so as to be adjusted each. CONSTITUTION:In the state that a spring support member 53 has strongly tensed a spring 50 at the center of an energizing force adjusting bolt 57, since a driven roller 30 is strongly pressed to a driving roller 10 by this spring 50 and a pressing stay 31, it comes to a state of being suitable for a taper strong in stiffness. Next, when such a tape as weak in the stiffness is delivered and cut, a screw 59 is loosed to some extent and a locking member 58 is moved to the right, rotating the adjusting bolt 57. Then, if the support member 53 is moved to the rear side of this bolt 57, pressing force by the spring 50 is weakened, so that the tape weak in the stiffness is deliverable with certainty. Thus, pressing force of the driven roller 30 by the spring 50 is simply alterable, and since various tapes T is accurately deliverable, so that several types of tapes T different in stiffness each can be cut by one tape delivery cutting device alone.

IPC: H01L29/10
Filed: 1979-09-21
Abstract: PURPOSE:To reduce the conductance of a field effect transistor by varying a channel width from a source side to a drain side and suppressing the increase in the gate threshold value of the transistor. CONSTITUTION:Channel, source and drain regions of a field effect transistor are defined by the pattern 10 of a gate insulated film, are separated by the gate electrode pattern 102, and a source 103 and a drain 104 are thus formed. The channel is now formed of a series connection of two sections having sizes of W1Xl and W2Xl2. The drain current can be reduce to approx. 65% in case of the channel having 2l1=L and W1=2W2 as compared with the case of the channel having constant W1 according to this configuration. Even if the width W2 is sufficiently decreased, the short channel effect cancels the narrow channel effect in the channel region of the drain side, so that the threshold voltage can be set at the generally same as the source side. Even if the channel width is continuously reduced from the source side, similar effect can be obtained.

Title: Field effect transistor

IPC: H01L29/786
Filed: 1992-04-17
Abstract: PURPOSE:To alleviate an electric field intensity near a drain region even in the case of a normal structure type. CONSTITUTION:The thickness of a gate insulating film 16 is gradually reduced from a side of a source region 13 toward a side of a drain region 14. When a positive gate voltage VG is applied to a gate electrode 17, electrons are induced in a channel region 15. In this case, since the thickness of the film 16 is reduced near the region 14, more electrons are induced in the region 15 near the region 14. As a result, in an ideal case, as shown by broken lines in Fig. (A), a width of a channel to be formed in the region 15 becomes constant with respect to a channel direction. Further, a potential V in a boundary between the region 15 and the film 16 becomes linear as shown in Fig. (B) (where L is a length of an effective channel) in which a position (y) along the region 15 is an abscissa axis, and an electric field intensity becomes constant with respect to the channel direction.
