Title: Dot printer
Inventor: KIKUCHI GOROU
IPC: G06K15/10
Filed: 1984-01-31
Abstract: PURPOSE:To obtain high-density printings by varying the densities of printing by only one printing head by a method in which a printing head is rotatably supported, and a setter to set up non-inclined and inclined positions is provided. CONSTITUTION:A printing head 1 is rotatably supported by a boss 14 on a plate 2A and is turned only by angles to be determined by the length to both ends of an opening 15 by means of a slide lever 16. When the lever 16 is slided to the right direction and positioned to the right end 15b of the opening 15, the interval d-1 in the vertical direction of a pin 1B becomes dcostheta, or becomes smaller than the distance (d). When the printing head 1 is turned and printing is made by delaying the operating timing only by the bias d-2 in the horizontal direction of each pin 1B, the interval between dots becomes d-1, permitting high- density printings to be performed.

Title: Encoding method and decoding method for dynamic image signal
Inventor: MACHIDA YUTAKA
IPC: H04N19/60
Filed: 1995-01-31
Abstract: PURPOSE: To perform decoding correctly timewise in subframe units even after part of a bit stream is absent or an error occurs and to suppress deterioration in decoded picture quality small even if the decoding of a subframe containing an image having motion with time is disabled. CONSTITUTION: Information of one frame is encoded corresponding to the spatial hierarchical structure of frames, subframes, and blocks and a time subframe number SFNT and a spatial subframe number SFNS are added to a subframe identifier SFSC to enable decoding which is correct with time from a subframe right after an error occurs. Further, SFSCs are arranged at constant intervals on the bit stream to make a subframe containing a block, which has motion with time and is difficult to encode, spatially small, thereby suppressing deterioration in decoded picture quality small even if it becomes impossible to decode the subframe.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To produce a coil having a good surface characteristic with good yield by deviating a pass line from horizontal to accelerate scale peeling and removing the peeled scale by secondary cooling water. SOLUTION: Molten steel 9 is supplied into a casting mold 1 and a slab 11 is cast. The thin slab 12 is formed by unsolidification rolling down within a rolling down zone 7 of a roller apron zone 2. The thin slab 12 with which the unsolidification rolling down in the rolling down zone 7 is sent to a pinch roll zone 3. The thin slab 12 is, thereupon, deformed to a corrugated shape while the thin slab is subjected to secondary cooling by alternately and successively moving pinch rolls 8 up and down from the path line by lifting cylinders 5'. Namely, the pass line is deviated from the horizontal with respect to the thin slab 12, by which the scale peeling of the surface is accelerated. The peeled scale is removed by the secondary cooling water. As a result, the inexpensive process is embodied without spending the useless equipment space and cost.

IPC: H01L23/50
Filed: 1981-02-04
Abstract: PURPOSE:To improve reliability by preliminarily forming a metal coating having excellent oxidizing corrosion resistance on the lead part on which external metal coating is no longer coated because of the presence of a thin resin film, which is attached when the resin is sealed, thereby avoiding the oxidizing corrosion. CONSTITUTION:The noble metal coating 204 is formed on the part to which a bonding wire 206 is to be connected on a lead frame 200, and the oxidation resisting metal coating 210 such as Ni and Ag is formed on a boundary part which is sealed by the resin 207. After the semiconductor 205 is placed on the lead frame 200, sealing is performed by the resin 207. When the external metal coating is formed on externl leads 202, said metal coating is not formed on the boundary of the resin sealed part due to flash. Even through the flash is peeled off later, the part is not corroded owing to the presence of the oxidation resisting metal coating 210.

Title: Drill
Inventor: HOSOI TOSHIAKI
IPC: B23B51/00
Filed: 1987-01-26
Abstract: PURPOSE:To prevent rotating resistance from increasing and to prevent a marginal section from being damaged, by forming outer peripheral cutting edges extending in a substantially axial direction from the outer peripheral ends of a pair of tip end cutting edges, and by setting the diameter of a circular locus depicted by the cutting edges to be greater than the outer diameter of the shank of the drill. CONSTITUTION:Tip end cutting edges 3 cut the bottom surface of a drilled hole, and simultaneously, outer peripheral cutting edges 20 cut the inner wall 100 of the drilled hole. Further, during the above-mentioned drilling, even though heat generation due to the cutting causes the forward end of the drill to expand, the outer peripheral cutting edges 20 cuts into the inner wall 100 of the drilled hole only by a degree corresponding to the expansion. Thus, during deep drilling, no rotating resistance is increased so that the drill may hold a satisfactory cutting performance for a long period, thereby it is possible to increase the life of the drill.

Abstract: PURPOSE:To obtain a thin film magnetic head of a two element type which is suitable for a high density recording and also can execute recording and reproduction with a high efficiency by forming a joint part to which the lower magnetic layer and the upper magnetic layer contact, in a nearly trapezoidal or triangular shape. CONSTITUTION:A joint part 7 is formed in a trapezoidal shape, and as for this trapezoid, against a length (a) of the upper bottom positioned at a sliding surface 6 side, a length (b) of the lower bottom opposed to said upper bottom is made large, and one side of other laminated body side is vertical to the upper bottom. Therefore, even if the length of the upper bottom of the joint part is the same as or below the length of the horizontal direction of a conventional joint part, the length of the side of the joint part being near its magnetic gap can be enlarged by enlarging the length of the lower bottom, and the recording and reproducing efficiency of a magnetic head can be improved. Also, one side piece of other head element side is vertical to the upper bottom to each other, therefore, an inter-track guard band TG can be held in a small width, and the magnetic head can execute a high density recording by having a narrow track width TW and the inter-track guard band TG.
