Title: Optical disk and its production
Inventor: YONEMURA ARITAMI
IPC: G11B7/2405
Filed: 1992-02-28
Abstract: PURPOSE:To increase the density of the optical disk which is constituted by coating at least the photoirradiated surface of the optical disk with a resin coating film and to improve the productivity thereof by forming the coating film to the film thicknesses having the uniformity of a specific range. CONSTITUTION:The optical disk is so formed that the thickness of the coating film 6 thereof satisfies 1000x(Do-Di)/(Ro-Ri)<0.02. The quantity at which the film constituting components are concentrated to the resin is low in such a case and, therefore, the influence on the warpage over the entire part of the optical disk is small and the quantity thereof can be suppressed at a low level. Then, the optical disk which is efficient and is suitable for high-speed rotation with decreased warpage is obtd. The optical disk having the higher density is thus obtd. and a great contribution is made on the improvement in the productivity in production. In the equation, Do is the coating film thickness (mm) in the outermost peripheral part of the recording film forming part, Di is the coating film thickness (mm) in the innermost peripheral part of the recording film forming part, Ro is the radius (mm) in the outermost peripheral part of the recording film forming part, Ri is the radius (mm) in the innermost peripheral part of the recording film forming part.

Title: Image device
Inventor: MURANO SHUNJI
IPC: B41J2/45
Filed: 1992-02-28
Abstract: PURPOSE:To form clear and accurate latent image or generate accurate electric signal and make the whole device small in size by a device wherein a plurality of light receiving/emitting element arrays are mounted linearly on one main face of a plane transparent substrate such that their light receiving/emitting faces are on the side of the transparent substrate, and lenses are attached on the other main face through a transparent member whose refractive index is larger than that of air. CONSTITUTION:In an image forming device, for example, a plurality of light-emitting diode arrays 2 whose light-emitting faces are on a side of a transparent substrate 1 are mounted linearly on the bottom face of the transparent substrate 1 consisting of light transmitting and insulating material. On one face of the transparent substrate 1, opposite to the face on which the light-emitting diode arrays 2 are mounted, a plurality of lenses 3 are fixed so as to oppose each light-emitting diode array 2 through a transparent member 5. As the refractive index of the transparent member 5 is higher than that of air, even if the focus distance of the lens 3 is made to be longer to a certain extent corresponding to the distance between the lens 3 and a photosensitive body, the distance between the light-emitting diode array 2 and the lens 3 can be shortened by providing the transparent member 5 having high refractive index.

Title: Manufacture of semiconductor device
Inventor: ISHIMOTO YASUMI
IPC: H01L21/768
Filed: 1999-02-22
Abstract: PROBLEM TO BE SOLVED: To permit the reformation of a wiring without being accompanied with the variation of the characteristics of a device and moreover, in a simple process by a method wherein a first insulating film is formed and a second insulating film having a selectivity of etching higher than that of etching of the first insulating film is formed on the first insulating film. SOLUTION: In the case where a out-of-standard defect is not discovered in the result of an inspection of a patterning, a gate oxide film 2 is made to expose. Then a conductive film of a thickness full to fill grooves formed in a second insulating film 4 and a first interlayer insulating film 3 is formed. In the case where the out-of-standard defect is discovered, the process, which extends to the time of the discovery, is redone. A leaving resist film 5 is removed by peeling off and moreover, the films 4 and 3 are etched away in order. As the conductive film is not still formed in the stage of an inspection of a pattern, the formation of the conductive film and a peeling process can be omitted. Moreover, the reformation of a wiring pattern can be conducted without peeling off a gate oxide film 2 formed under the film 3.  Thereby, the variation of the characteristics of a device, which is accompanied with the reformation of the wiring pattern, is lessened.

Title: Vibration control device
Inventor: KAWASHIMA TAKASHI
IPC: F16F13/08
Filed: 1992-02-28
Abstract: PURPOSE:To reduce the high frequency vibration by providing a partitioning wall to partition a liquid chamber into two smaller liquid chambers composed of an elastic body, a limiting passage communicating the smaller liquid chambers to each other, a vibrating body to permit a minute expansion/contraction of the smaller liquid chambers, and an interrupting member which is vertically provided on the vibrating body and forms a narrow part between the vibrating body and the elastic body. CONSTITUTION:When the engine is in operation, the vibration is transmitted to an elastic body 18 through a supporting member 20, and absorbed by its internal friction. When the frequency of the vibration is increased, a limiting passage 34 absorbs the vibration by the liquid passing resistance, and when the frequency is further increased, the limiting passage 34 gets clogged. But a vibrating body 42 achieves a minute vibration and the rise of the pressure in the upper and the lower smaller liquid chambers 26A, B is limited, leading to absorption of the vibration. When the frequency is further increased, a reduced-diameter part 48 of the vibrating body 42 is brought into contact with a partitioning wall 28 or an abutting plate 30, and the increase of the dynamic spring constant can be avoided by the resonance of the liquid column when the liquid in the upper smaller liquid chamber 26A passes through a narrow part 60, leading to absorption of the vibration. Since the interrupting member 54 is formed on the side of the elastic body 18, no inconveniences are met in achieving the vulcanizing adhesion of the elastic body 18, reducing the number of the parts.

Title: Synchronous binary counter
Inventor: ISHIKAWA KEIJI
IPC: H03K23/50
Filed: 1985-03-06
Abstract: PURPOSE:To realize a counter with large number of digits with a small number of gates by connecting alternately in cascade two kinds of carry look-ahead counter circuits having a carry propagation circuit comprising a NAND gate and a NOR gate only. CONSTITUTION:The least significant digit is constituted by a T-FF, the carry is outputted by a positive logic and the 2nd and succeeding digits are connected alternately in cascade in the order of a counter circuit 2, a counter circuit 1, a counter circuit 2, .... Since the synchronous binary counter is constituted that the counter circuit 1 inputting the carry by positive logic and outputting it in negative logic and the counter circuit 2 inputting the carry in negative logic and outputting it in positive logic are connected alternately, the carry transmission is attained by using the NAND gate and the NOR gate only. Thus, in realizing the circuit by an MOS circuit having NOT logic as a basic gate, the logical number of stages for the carry propagation is less and since the carry is propagated by look-ahead in the counter circuits 1 and 2, high speed operation is attained.
