Title: Magnetic recording medium and its production
Inventor: MATSUMOTO HIROYUKI
IPC: G11B5/725
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To obtain a high-recording density magnetic recording medium which is lowered in surface oxygen concn., is capable of maintaining lubricity over a long period of time and has an excellent sliding resistance characteristic by subjecting the protective film surface on a nonmagnetic base to a plasma treatment with a gaseous mixture contg. hydrogen. SOLUTION: An Ni-P plating layer is formed as a hard ground surface layer 2 on an Al-Mg alloy substrate 1 and a ground surface Cr layer 3 which is a nonmagnetic material is formed thereon. M Further, a Co alloy magnetic film 4 and a carbon film as a hard protective film 5 are formed thereon. At this time, the surface of the protective film 5 is subjected to the plasma treatment within a vacuum discharge system by the single gas or gaseous mixture contg. hydrogen and gaseous hydrocarbon, by which the surface oxygen concn. is suppressed or lowered to <=10atom. Next, a lubricant is applied on this surface and is subjected to a heat treatment for two hours at 120'C to form a lubricative film 6.  The chemical compsn. at the boundary between the protective film surface and the lubricative film is optimized in such a manner, by which the high-recording density magnetic recording medium capable of maintaining the lubricity over a long period of time and having the excellent sliding resistant characteristic is obtd.

Title: Lockup control valve for automatic speed changer
Inventor: TATE YOSHITERU
IPC: F16H61/14
Filed: 1983-08-20
Abstract: PURPOSE:To prevent generation of speed change shock by selecting the area of a lockup control valve to bear the bias pressure greater than its area to bear the control pressure. CONSTITUTION:The area SB of a lockup control valve 17 to bear the bias pressure PB is selected greater than its area SC to bear the control pressure PO. Thereby the lockup control valve 17 can operate quickly in the converter direction and slowly in the opposite, i.e. lockup direction. This eliminates generation of speed change shock likely to occur when speed change is performed by an automatic speed changer owing to the torque converter being put in locked- up state.

Title: Semiconductor storage
Inventor: KOKUBU KUNIO
IPC: H01L27/10
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption in a memory cell with low breakdown strength by applying a first voltage of first polarity to a control gate and applying a second voltage of second polarity opposite to the first polarity to a first area at a carrier pull-out time pulling a carrier out from a floating gate. SOLUTION: A controller 1 receives the address data and the control data supplied from the controller through buses 11, 12, and controls three states of write/read/erase of the data for the memory cell based on the address data and the control data. By lowering the potential of the control gate at an electron pull-out time, and also lowering a drain voltage, since a potential difference between a drain and a well is reduced while holding the large potential difference, the occurrence of a hot carrier in a drain junction is suppressed.

IPC: H03H3/04
Filed: 1977-12-16
Abstract: PURPOSE:To improve the yield and precision of a crystal vibrator and to lower its price by improving frequency-temperature characteristics by varying the length of a bevel part. CONSTITUTION:By varying the length of bevel part 3 of bevel-worked thickness slide crystal vibrator 1 with exciting electrode 2, frequency-temperature characteristics of vibrator 1 can be varied. As the vibration range becomes smaller, the variation of the temperature characteristics against the variation of the length of bevel part 3 becomes greater and this effect is remarkable as to a miniature vibrator. Therefore, frequency-temperature characteristics are improved by varying the length of the bevel part of vibrator 1 to make it possible to use a defective blank which was not used so far, so that highprecision and inexpensive vibrators can be obtained at high yield.

Title: Manufacture of sintered high-speed steel
Inventor: SHIMAMURA KEIZOU
IPC: B22F3/10
Filed: 1977-12-20
Abstract: PURPOSE: To obtain inexpensive sintered high-speed steel of a high tenacity by the procedure in which alloy constituents, e.g., Cr, W, Mo, V, Ti, etc., in the form of oxide are added, oxidized iron powder is reduced by excess carbon, and the amount of carbon is controlled so as to optimalize it after sintering.  
     CONSTITUTION: Alloy constituents consisting of 3 to 6% Cr carbide and 5 to 50% at least one of the carbides of W, Mo, V, and Ti are mixed with iron powder and then ground into fine powder. The mixed powder is then molded into a porous body of a density ratio of 40 to 60% and then subjected to a deoxidation-decarburization treatment at 900 to 1050°C under cacuum. Afterwards, it is baked by heating at less than carbide crystallization temperature. The porous sintered body thus obtained is again heated to 1100 to 1200°C in a current of hydrogen, kept for a fixed hour under the condition, and then taken out of the furnace to forge it by one time striking within 1 to 2 seconds by using a high-speed and high energy processing machine. This method enables one to obtain easily a sintered high-speed steel having a density ratio of approx. 99.9% and a high tenacity at lower cost.
