Patent JP-H0836789-A (JP)
Title: Manufacture of optical disk
Inventor: YOSHIDA IKUO
IPC: G11B7/26
Filed: 1994-07-21
Abstract: PURPOSE:To form a protective film surface having flat and uniform coating surface by a continuous production system by forming a protective film coating under a specific condition. CONSTITUTION:A protective film coating material is prepared from an ultraviolet curable resin or mixture of the resin with solvent to provide the viscosity of 2-30cps. In this case, when the viscosity is within this limit or higher, the coating surface becomes rough as sprayed particle state, while when it is within this limit or lower, it becomes difficult to place necessary resin quantity in a predetermined film thickness on a substrate. The substrate temperature is set to 23 deg.C or higher, heated simultaneously upon coating, and its leveling is expedited. However, when it exceeds 90 deg.C, the viscosity decrease becomes remarkable, and suitable coating quantity is difficult to be obtained. At 23 deg.C or lower, the leveling becomes unstable, and flatness cannot be obtained. At the time of leveling for 2 seconds or longer before ultraviolet curing, the leveling of the coating film is advanced by horizontally holding it. Thus, the protective film surface having excellent flatness and uniform coating surface can be obtained.

Title: Semiconductor memory circuit
Inventor: SHIMADA HIROSHI
IPC: G11C5/02
Filed: 1979-12-27
Abstract: PURPOSE:  To reduce power consumption to half and to enable a semiconductor memory circuit to perform high-speed operation, by selectively closing right and left memory cell group driving gates according to the discrimination result of a discriminating circuit.  
     CONSTITUTION: At the left and right sides of a word decoder, left memory cell group ML driving gate 21L and right memory cell group MR driving gate 21R are provided, and the both are selectively closed by the output of discriminating circuit 22. Circuit 22 receives column-side addresses ADCL1WADCLn, and ADCR1W ADCRn in parallel to discriminate whether an assigned memory group belongs to the left or right side. When memory cell group CL1 is assigned, [left memory cell group assigned] is discriminated and the result is outputted. Consequently, while gate 21L is opened, gate 21R is closed, and consequently the right side part of word line WLK is not driven, so that the corresponding bit current will be ceased. As for the right side, the same operation is performed. Therefore, the bit current is reduced to half and the need to drive all cells at a time is eliminated, so that high-speed operation will be possible.

Filed: 1993-07-08
Abstract: PURPOSE:To provide a semiconductor device and its manufacturing method which can reduce the dimensions of an element as well as parasitic resistances such as gate resistance, source resistance, drain resistance, and the like. CONSTITUTION:In a minute concave MOSFET, a groove opening becomes extremely narrow. This groove is normally formed by etching. After it is subjected to gate oxidation, polysilicon is deposited to fill the groove. Further, even when the entire surface of the substrate is treated with etchback, if etching conditions are to be selected, only the inside of the groove can be left with polysilicon as the electrode, and, if etching time is properly selected, the upper side of polysilicon can be made lower than the upper end of the periphery of the groove. By making the structure in this way, it is possible to form a sidewall insulating film 9 inside the groove, and with this sidewall insulating film, silicide 12 on the gate electrode 8 can be physically and electrically isolated from silicide 10 and 11 on a source electrode 3 and a drain electrode 4.

Filed: 1990-06-27
Abstract: PURPOSE: To prevent ununiform abrasion of a lining on a brake pad by providing a range smaller than the engaging front surface range of a second limb on the rear side edge to a boss of a first limb of an arm member front edge side, and providing lower flexibility to the first limb. CONSTITUTION: A boss 32 of a first limb 28 is provided with the front surface range A smaller than the front surface range B of a boss 34 of a second limb 30 and to be brought into contact with an outer brake pad 16. Moreover, the limb 28 is provided with a relative rib 36, and the rib 36 has lower flexibility than the limb 30. Accordingly, in the small front surface range A, the front edge side of the outer brake pad 16 receives the larger pressure action in comparison with the rear edge side when a driver of a vehicle operates a disc brake 10. Moreover, the rib 36 makes the limb 28 more rigid than the limb 30, and therefore, the first limb is made flex under the second limb and taken as a means for generating uniform abrasion of a brake pad lining.

Title: Light gain medium, light amplifier, and semiconductor laser which is tunable
Inventor: DEIITORITSUHI KERUPUSU
IPC: H01S5/00
Filed: 1990-06-27
Abstract: PURPOSE: To amplify a wide-band light amplification by introducing the high- concentration impurity of a semiconductor light gain medium and hence expanding an interval between pseudo-Fermi levels of a conduction band and a valence electron band and narrowing the effective prohibition band energy gap between the conduction band and the valence electron band. CONSTITUTION: The forbidden band of a gain medium that is constituted of III-V material system is decreased by the reduction in the forbidden band caused by a high-concentration free carrier and a band tailing due to high-concentration n-type impurity introduction and extends the low-energy edge of a gain range. When the III-V gain medium is introduced to a high-concentration n-type impurity, the gap of the pseudo-Fermi level for a given injection carrier concentration increases and the high-energy edge of the gain range of a used device is extended.  When a material system with a conduction band in high-concentration electron state and a valence electron band in low-concentration positive-hole state is used, the potential of the prohibition band is decreased and the gap of the pseudo-Fermi level is increased, so that a high-concentration p-type impurity must be introduced instead of a high- concentration n-type impurity for the gain medium, which is opposite to the III-V material system.
