Title: Semiconductor device
Inventor: MIKINO HIROSHI
IPC: H01L23/495
Filed: 1982-09-06
Abstract: PURPOSE:To prevent the production of an improper external appearance of a semiconductor device by allowing the minimum sectional position of a pinch-off part forming a tab lead to coincide with the outside surface position of a package body, thereby reducing the exposing area of the tab lead pinch-off part to suppress the adherence of solder to the exposed surface. CONSTITUTION:The outer surface 18a of a package body 18 is disposed at the pinch-off part 17 of a tab lead 13, and the outer surface 18 is allowed to coincide with the minimum sectional position 17a. In other words, it is constructed so that the outer surface 18a of the package body 18 is contacted with the thinnest position of the tab lead 13. Thus, the tab lead 18 is cut a the pinch-off part 17, the lead 14 is cut at the frame 11, and even if it is bent or cut, the cut surface of the lead 13 which is exposed partly at the outer surface 18a becomes the minimum sectional area position, and the exposed area becomes extremely small. Accordingly, when the lead is dipped in the solder in the solder coating of later step, the solder is hardly bonded to the exposed surface of the lead 13.

Title: Field effect transistor and production process thereof
Inventor: YANAGAWA HIROSHI
IPC: H01L29/78
Filed: 1994-07-06
Abstract: PURPOSE:To reduce the continuity resistance and improve the switching speed by forming a collector region in an expanded drain region and a field relaxation layer of a reverse conductivity type to the drain region in this region. CONSTITUTION:When a voltage over VT is applied to a gate electrode 28, the conductivity of a region near the surface of a channel forming region 25 is inverted to an n-type to form a channel region which makes a source and collector regions 26 and 24a conductive. At this time, holes from the p-type collector region 24a are fed into an expanded drain region 24 to increase the flow rate of electrons and thus, the apparent continuity resistance between the regions 26 and 24a is reduced. When a voltage below V1 is applied to a gate electrode 28, the channel region disappears and a depletion layer expands from a p-n junction of the drain region 24 into this region, thereby isolating the region 24a from the source region 26. Since holes are recovered by a field relaxation layer 27 and substrate 23 at this time, the switching time is reduced enough for a high speed operation.

Filed: 1994-06-14
Abstract: PURPOSE: To provide a system for transmitting data signals and voice signals which can widen the dynamic range of the voice signals even when an error is deliberately introduced to the transmission of the data signals. CONSTITUTION: In a communication system, the signal space of a signal point array is divided into a plurality of regions by using an error correcting technique, such as the channel encoding, etc., and at least one region overlaps with another region. Data signals on a line 501 are channel-encoded and selects a specific one of the regions and the region is represented by a reference signal point value. Sound signals on a line 549 are encoded and form a signal point vector and the vector is added to a reference signal point to obtain a signal. The obtained signal is rotated in the overlapping area so as to deliberately introduce an error to a transmitted signal point system. Regardless of the deliberately introduced signal point, a receiver reproduces the original selected reference point value through the channel-encoding of the data signals and simulates the voice signals by using the reference point value.
