Patent JP-S6235538-A (JP)
Title: Semiconductor device
Inventor: SUGURO KYOICHI
IPC: H01L21/28
Filed: 1985-08-09
Abstract: PURPOSE:To perform a stereoscopic wiring structure using high melting point metal without increasing a wiring resistance between upper and lower layer semiconductors by using the high melting point metal in the connection between the wiring layers of the upper and lower layers and forming the connector of the metal with the layers of the nitride of the metal. CONSTITUTION:A diffused layer 12 is selectively formed on the surface of a silicon substrate 11. A silicon layer 17 is formed through a silicon oxide film 13 on the substrate 11, and a diffused layer 18 is formed at part of the layer 17. A sandwich structure of a high melting point metal film 15 and high melting point metal nitride films 14, 16 is used for the connection of the layers 12, 18. Thus, the sandwich structure that the film 15 is interposed between the films 14 and 16 is used in the connection between the layers 12 and 18 of upper and lower silicon layer to prevent the silicide of the film 14. Further, since the contacting resistance of the nitride films with the silicon is low, the wiring resistance can be reduced.

Title: Window structure
Inventor: SASAJIMA TETSUO
IPC: B61D25/00
Filed: 1993-07-14
Abstract: PURPOSE:To dissolve disadvantage in the case of negative pressure acting upon the outer window glass of a vehicle. CONSTITUTION:When a train enters a tunnel or passes by an opposed train, the outside pressure of the train is fluctuated in large degree, and according to the pressure fluctuation, a diaphragm 12 moves as shown by an imaginary line. That is, when the outside pressure becomes high, the diaphragm 12 is deformed in the direction of reducing the volume of a first pressure chamber S1, and when the outside pressure becomes low, the diaphragm 12 is deformed in the direction of enlarging the volume of the first pressure chamber S1. As a result, the outside pressure and the pressure of a space S3 become approximately equal.

Title: Photoelectric conversion device
Inventor: OGAWA MINORU
IPC: H04N5/335
Filed: 1986-07-24
Abstract: PURPOSE:To enlarge the width of a channel so that it is not restricted by the density of arrangement of photoelectric conversion elements and thereby to enable an increase in a value of current on the occasion of switching by forming the channel of a thin-film transistor in a shape wherein it is perpendicular to the direction of an array of the photoelectric conversion elements. CONSTITUTION: A channel 13 is formed in a shape wherein it is laid in the perpendicular (vertical direction) to the direction of an array (lateral direction) of photoelectric conversion elements. In other words, a source electrode 11 and a drain electrode 12 are so formed that they are separated from and opposite to each other in the direction of the array. Since the width W2 of the channel is secured in the direction perpendicular to the direction of the array therefore, the width W2 can be made so large that it is not restricted by the density of arrangement of the photoelectric conversion elements, and consequently the degree of freedom thereof is increased. This enables the increase of a value of current on the occasion when a thin film transistor switches over the photoelectric conversion element corresponding thereto, and thus reading of picture information can be ensured.

Title: Magnetic picture recording and reproducing device
Inventor: NAKAJIMA YOSHIRO
IPC: H04N5/782
Filed: 1986-07-25
Abstract: PURPOSE:To record another video information while leaving already recorded information as it is, by erasing information at every other video track of an already recorded tape with an erasing head and writing information to erased track parts. CONSTITUTION:An input video signal is delayed by a prescribed time in a synchronizing circuit 2 to match the timing to the reproduced video signal form a VTR 4, and the delay signal is taken out by a switching circuit 3 and is applied to a head B only when a head switching signal is in a low level. Since the beat disturbance is occurred by double writing if the already recorded signal is left as it is in this case, only information on the track which is the locus of a head B is erased by a flying erase head 12 in adance of the head B. Thus, already recorded information of video A is preserved in every other field, and the newly inputted information of video B is recorded in every other fields.

Title: Golf ball
Inventor: MAEHARA KAZUTO
IPC: A63B37/06
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To add performances which could not be given from a golf ball made of only a plastic material and rubbery material to a golf ball. SOLUTION: This golf ball comprises a layer of a shape memory metallic alloy. For example, a layer 6 prepared by winding fine strands of a shape memory metallic alloy is inserted between a core 2 and a cover 4. When thus it is made, the shape memory metallic alloy layer 6 exhibits a function tightening the core 2 and results into a higher resiliency of the golf ball, and flying distance is increased. Further, owing to the high specific gravity of the shape memory metallic alloy layer 6, an inertia moment of the golf ball becomes greater thereby spinning performance and the rolling performance of the golf ball are increased. Also, the shape memory metallic alloy layer 6 having a high strength and high hardness exhibits a function as a reinforcing layer for the cover layer, therefore, cut resistance of the cover layer and durability against impact are improved.
