Title: Magnetic recording medium
Inventor: SATO TOSHIHIKO
IPC: G11B5/66
Filed: 1989-02-22
Abstract: PURPOSE:To obtain the recording medium having good traveling property and durability even at high temp. and high humidity by incorporating one type of discrete granular projections having specified dimensions and another type of discrete granular projections having different dimension from the above- mentioned projections in the surface of the ferromagnetic metal thin film. CONSTITUTION:The magnetic recording medium comprises a flexible plastic supporting body and the ferromagnetic metal thin film provided thereon. This ferromagnetic metal thin film has the discrete granular projections S having 100 - 200Angstrom  height, 800 - 1,500Angstrom  mean granule size and (2 to 16) X 10<6>/mm<2> density, and another type of discrete granular projections L with 100 - 600Angstrom  height, 2,000 - 6,000Angstrom  mean granule diameter and (1 to 8) X 10<4>/mm<2> density. The projections S are made by the filler particles contained in the base layer provided on the supporting body, while the projections L are made by the filler particles incorporated in the supporting body. Thus, the obtd. tape having both large projections and small projections resulted from the large-size filler particles L and small-size filler particles S, respectively, has excellent durability and reliability compared to such a tape having only one of the two fillers.

Filed: 1980-03-31
Abstract: PURPOSE:To lower the frequency handled with a circuit and a transmission line, by splitting photo information signal of a line shape photodetector at a read-in section and transmitting them to a recording section by a plurality of bits. CONSTITUTION:The output of the line shape photodetector consisting of 1728 sets of detectors, for example, is read out N times in parallel with a plurality of bits every M-bit, and that is, it is equally divided into, e.g., 54 divisions, and the information in 32-bit is assigned per one block. Further, the information in 1728-bit is transmitted to the recording section by sequentially switching it in 32-bit and dividing it into 54-times. The recording section forms the video information for one line's contents through the use of information for 54-times' contents for recording.

Title: Rolling mill
Inventor: TERAKADO RIYOUJI
IPC: B21B1/22
Filed: 1978-04-11
Abstract: PURPOSE: Extremely small diameter working roll and relatively large diameter roll are combined to efficiently perform a high reduction rolling.  
     CONSTITUTION: A rolling system consists of a center working roll 1 and radially arranged periphery working rolls 2,2', 2". A strip 3 advanced from the upper portion of the periphery working roll 2 at obliquely above, passes through A between the periphery roll 2 and the center roll 1, and through B between the center roll 1 and the bottom periphery roll 2' enclosing the center roll 1. The strip, further enclosing the center roll 1 and contacting with the other periphery roll 2" at obliquely above, moves upwards. When the center roll working roll is extremely small as in this invention, in which the rolling reaction and the rolling torque are reduced, the periphery rolls can be made smaller without losing strength. For such small working center roll, super hard alloy roll can be used.

Title: Semiconductor device
Inventor: KIKUCHI MASAYUKI
IPC: H01L21/8238
Filed: 1989-02-27
Abstract: PURPOSE:To avoid channeling of ions in a gate electrode and increase the resistance of the gate electrode by a method wherein the gate electrode is made from a laminated unit composed of a polycrystalline silicone layer and an amorphous silicon layer. CONSTITUTION:As an amorphous silicon layer 8 free from grains causing channeling is formed on a polycrystalline layer 7 of which a gate electrode 9 is composed, channeling in the gate electrode produced when ions are implanted for forming source and drain is blocked by the amorphous silicon layer 8. Further, if a thermal treatment is performed after the amorphous silicon is doped with impurity, the resistance of the amorphous silicon becomes lower than that of polycrystalline silicon by about 20% and hence the resistance of the gate electrode 9 is reduced. With this constitution, a MOS-FET which has no channeling in its gate electrode 9, has stable characteristics and, further, has the low gate electrode 9 resistance can be obtained.
