Filed: 1986-10-22
Abstract: PURPOSE:To reduce the ventilation resistance to exhaust gas and to increase the surface area of a waveform by laminating a metallic corrugated sheet having a specified rugged shape and flat sheets, and winding the sheets in multiple layers to form a core part, and using the core part to form the title metal honeycomb carrier. CONSTITUTION:The corrugated sheet 33 is arranged between the flat sheets 31, and the rugged shape of the corrugated sheet 33 is formed by a convex semicircle 35 having a radius R and a concave semicircle 37 having a radius R and connected to the convex semicircle 35. Namely, the concave semicircle 37 is connected to both ends of the convex semicircle 35 while sharing the same tangential line at the joint. When the width of one cell in the corrugated sheet 33 is assumed to be 4R, the height is 2R. Since the rugged shape of the corrugated sheet 33 is formed by the convex semicircle 35 having a radius R and the concave semicircle 37 having a radius R are connected to the convex semicircle 35 in the metal honeycomb carrier thus formed, the concave semicircle 37 never penetrates into the convex semicircle 35 side.

Title: Electron-emitting element, its manufacture, and image display device and its manufacture
Inventor: SHIRATORI TETSUYA
IPC: H01J1/304
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To provide an electron emission element, capable of extracting high current at a low voltage, and provide a flat type image display device with low voltage driving and high brightness and its manufacturing method. SOLUTION: The surface of a conducting layer 1 formed on a substrate is made rough, particles or aggregates of particles 2 are attached independently to the surface of the conducting layer 1 along the recesses and projections, without coming in contact with each other to form an electron emission part 3. Compared with formation on a flat conducting layer, electric field convergence is made high, and extracting of electrons is made possible by only applying low voltage to facing electrodes.  Since particles or aggregates of particles 2 for constituting the electron emission part 3 are independent without coming in contact with each other, each particle becomes the starting point or electron emission, electron emission current from the electron emission part 3 is formed by the accumulation of electron emission from the particles or the aggregates of particles 2, so that the current is made large and uniform spatially and temporally.

IPC: H04N5/44
Filed: 1991-09-30
Abstract: PURPOSE:To automatically receive the channel of the TV signal corresponding to the digital data by receiving the channel of the digital data at the reception side even if the band is narrow per channel. CONSTITUTION:A digital train (h) formed on a channel of the digital data received at the reception side is divided by a PCM decoder 9 into a sound signal part and an independent data part. The latter part is supplied to a CPU 25 via a data extracting circuit 11 as the independent data (m). The CPU 25 instructs a tuner 23 to select the channel of the TV signal shown by the data (m). Thus the channel of the TV signal corresponding to the digital data is automatically received at the reception side. In this case, only a single channel is designated for the independent data applied to the digital data on the channel of the digital sounds. Thus the band can be narrowed per channel.

Title: Jig grind processing method for metal mold plate
Inventor: GOTO TERUO
IPC: B24B1/00
Filed: 1992-08-27
Abstract: PURPOSE:To remove grinding heat quickly and efficiently, by arranging metal plates which are superior in their heat conductivity on a part to be processed, of a metal mold plate, and performing jig grind processing while forcibly cooling these metal plates. CONSTITUTION:Jig grind processing is applied on a metal old plate 1 such as a punch plate or a die plate, without using grinding lubricant. On a part, to be processed, of the metal mold plate 1, metal plates 6 which are superior in heat conductivity are arranged. A flexible hose (metal tube) is connected to these metal plates 6. Grinding heat generated by the jig grind processing is locally concentrated by these metal plates 6, and the metal mold plate 1 is cooled through natural heat radiation from the metal plates 6 and forced cooling performed by water flowing in the flexible hose 3. Consequently, grinding heat can be removed quickly and efficiently.

Abstract: PROBLEM TO BE SOLVED: To reduce a construction cost without damaging a bulkhead function by a method wherein when rectangular wire cages are piled up in a multistage, in the case the cage is filled with stones to construct a bulkhead, the cage having a partition net arranged in the cage body is used and the cage is filled in a state that filling stones of good quality and a material substituted for the filling stones of good quality are separated away from each other. SOLUTION: Mats 21 are laid over the whole surface of a slope 20 of a river, and rectangular wire cages 10 are piled up in a stair-form manner in a state that a position is displaced rearward from the lower side to the upper side of the slope 20, and suction of coil by flow water is regulated. In this case, the cage 10 formed such that a partition net is arranged in the cage body and the internal space of the cage body is partitioned into a plurality of sections is used. A range easily exercised by the influence of a flow force, i.e., a range where the bedding cage 10 is exposed is partitioned into narrow spaces along the direction of a water flow.  The influence of a water force exercised on filling stones 30 in a partitioned narrow space A is reduced to prevent the occurrence of deviation phenomenon of the filling stones 30, and a space B in a range wherein the influence of the flow force is hardly exercised is filled with a low-cost substitution material (false filling stones) 31 to effect economical stone- filling.

Thus, close adhesion of a coating film of oxalic acid salts is improved and consequently seizure resistance is execllent and phosphoric acid is unnecessary to be contained in the chemical conversion coating film soln. as in the conventional manner.  Further, pretreatments such as preimmersion in sulfuric acid, water compression, preheating of a base material are unnecessary and thereby reduction of equipment and installation area can be realized.
