Title: Surface mounting type resin seal type semiconductor device
Inventor: FUJITA KAZUYA
IPC: H01L23/31
Filed: 1988-12-15
Abstract: PURPOSE:To reduce the vaporization pressure under a high temperature at the time of soldering mounting, and restrain the increase of expansion stress by forming a resin film having high adhesion to both of a lead frame and sealing resin, on the rear of an island part. CONSTITUTION:A semiconductor chip 1 is mounted on the main surface of an island part 2 of a lead frame 4, and sealed with first resin 3. At this time, a film 6 of second resin is stuck on the rear of the island part 2 of the lead frame 4. The film 6 is a polyimide system film. As a result, when a package absorbs moisture, the water content does not concentrate on the interface between the island part 2 of the frame 4 and the film 6, and the interface between the film 6 and the resin 3. Thereby, the vaporization pressure at a high temperature at the time of soldering mounting is reduced, and the increase of expansion stress can be restrained.

Title: Vertical field effect transistor
Inventor: MORIMOTO KINSHIRO
IPC: H01L21/336
Filed: 1991-11-05
Abstract: PURPOSE:To reduce dispersions of Ron and Vth without lowering reverse breakdown strength by making a depth from a substrate region surface shorter than a transverse length of a substrate region which is covered with a gate electrode. CONSTITUTION:A pattern of a polysilicon electrode 7 is formed by deviating it by delta in reverse direction of a transverse diffusion direction from a P-type pattern by a thermal oxide film 8. As a result, a depth Xjp from a surface of a substrate region 2 is shorter than a transverse length XjpL of a source region surface which is covered with the gate electrode 7. Since a deviation length 6 is provided in this way, a maximum impurity concentration of the substrate region 2 wherein a channel is formed does not change even if a diffusion depth of the substrate region 2 (P) and a source region 3 (n<->) shows dispersions a little.

Title: Picture processing system
Inventor: HORI MITSUHARU
IPC: H04N1/40
Filed: 1988-12-16
Abstract: PURPOSE:To attain high definition binarization with the minimum memory capacity by correcting a selected reference slice level with a value obtained by multiplying the difference between the density of an object picture element and the average of the respective densities of the peripheral picture elements of the object picture element by a correction factor, and binarizing the density of the object picture element with the above-mentioned value as an effective slice level. CONSTITUTION:An appropriate reference slice level SBj to slice a black level and a white level is automatically selected for every original and for every area on every original according to the change of the density of the picture of every original and the change of the ground color of every original. Further, when an original picture having blurred shading or the blurred edge of a pattern part (contour part) is to be read, binarization processing is executed, in which the average density of the neighborhood area of an object picture element density S0 is made into the offset component of the object picture element density S0 and subtracted from S0 in a fixed ratio, and the change of the object picture element density S0 is emphasized, by setting a correction factor K to a comparatively large value.

Title: Acoustic flow velocity-measuring apparatus
Inventor: MORIMOTO NOBUO
IPC: G01P5/00
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To improve the measurement accuracy for gas flow velocity by sequentially obtaining the correlation of waveforms of a transmission signal and a reception signal at each time point, judging the time point at which the signal output is maximum as a time when the transmission signal reaches a receiver, and detecting the propagation time of sound waves between the transmitter and the receiver. SOLUTION: A transmission signal generator 23 generates a pseudo random signal having a autocorrelation. The signal is transmitted from a transmitter 1 into a gas flow channel as a flow velocity measurement sound wave. The sound wave received by a receiver 3 is sent to a matched filter 15 via a receive amplifier 9 and an A/D converter 11. A correlation at each point of a receive signal waveform and a transmission signal waveform is obtained. An output of the matched filter 15 becomes maximum when the signal waveforms are synchronized. Therefore, a propagation time detector 17 judges this time point as a reach time point when the measurement sound wave reaches the receiver 3 and obtains a propagation time of the measurement sound wave from a transmission time point and the reach time point.  A flow velocity operator 19 calculates the flow velocity of a gas from the propagation time, the average flow velocity of air, the sound velocity, the distance L between the transmitter and receiver 1 and 3, and the angle θ of a line connecting the transmitter and receiver.

Filed: 1994-12-21
Abstract: PURPOSE: To rapidly stop the ejection of a cooling liquid, improve the accuracy of the cooling temp. control of a material to be cooled and decrease the variations in the tensile strength, etc., of the material to be cooled by existing one-side ends of plural pieces of nozzles in the upper part in hollow bodies and forming at least one of plural pieces of the nozzles longer than the other nozzles. CONSTITUTION: The cooling liquid is ejected from the respective nozzles 50 for the specified time by a siphon phenomenon even if the supply of the cooling liquid to the hollow bodies 38 is stopped. However, the pulling force of the siphon phenomenon with the nozzles 50a shorter than the other nozzles 50 is smaller than that of the other nozzles 50 and, therefore, the ejection of the cooling liquid stops correspondingly faster and in addition, the air infiltrates from the ejection ports of these short nozzles 50a and the infiltrated air intrudes into the upper part in the hollow bodies 38. At this moment, the continuity of the cooling liquid is no longer maintained and the ejection from the other nozzles 50 is simultaneously stopped as well. Then, the effect thereof is higher as the nozzles 50a are formed shorter.  The bottom end positions of the nozzles 50a are most preferably set down to the bottom walls of the hollow bodies 38.
