Title: Method and device for encoding picture signal
Inventor: SHINBASHI TATSUO
IPC: H04N19/91
Filed: 1993-09-30
Abstract: PURPOSE:To balance the picture quality and the generated information amount in performing band division encoding for each block by performing encoding while converting a picture signal by taking the direction and length as reference when the alignment of the conversion coefficient of a picture signal is checked and coefficients higher than a threshold value are in line. CONSTITUTION:An input picture signal D11 is inputted to a macro block conversion circuit 11 to comprise the macro block(MB) and is outputted as an MB signal D12. The signal D12 is inputted to a Haar wabelet conversion circuit 12 and is two-dimensional wavelet converted into a conversion coefficient D13. As the preprocessing, a picture signal D12 is converted to check the alignment of the conversion coefficient D13 for each block. When a coefficient higher than a threshold value is in line, the base selection is performed by taking the direction and the length as reference and the signal D12 is converted into encoding. When there is no directivity horizontally and vertically and when there is directivity horizontally and vertically, the directivity of the block suitable for the visibility can be detected according to the selection reference using the total coefficients over the threshold value. Thus, the division conversion base less affecting on the visual picture can be selected.

Filed: 1993-09-30
Abstract: PURPOSE:To prevent short-channel effect by forming a gate electrode so as to enter a recessed area formed between source region and drain region provided on a semiconductor substrate. CONSTITUTION:A n<+> type source region 12 and a drain region 13 are formed on a p-type semiconductor substrate 11 and a gate electrode 15 is also formed so as to enter the recessed area between such regions.

Title: Paving method
Inventor: ITO KAORU
IPC: E01C7/30
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To prevent the surface applied with a hydrophilic and/or water- adsorptive epoxy resin as an uncured resin from peeling off or cracking even when wet aggregate is used, by using the above resin when a mixture of aggregate and the uncured resin is supplied on the surface covered therewith and the uncured resin is cured. SOLUTION: An epoxy resin is constituted of a bisphenol A epoxy resin, an emulsion type curing agent chiefly composed of a modified aliphatic polyamine, and an additive providing hydrophilic and/or water-adsorptive properties. A mixture of the epoxy resin and aggregate is applied on a surface and the epoxy resin is cured. In this way, even if the aggregate is wet, a paving face without peeled or cracked parts can be obtained. Even natural aggregate can be used without drying it and hence, the execution cost can be reduced.

Filed: 1991-09-18
Abstract: PURPOSE:To improve the high-frequency characteristic of a choke coil. CONSTITUTION:In a choke coil which is composed of a ferrite core 1 and a coil formed by winding a conductor 2 around the ferrite core 1, the followings are installed: a plurality of circuits which are arranged and installed in a plurality of nearly loop positions of voltage standing waves distributed in the axial line direction of the coil, which are insulated from the conductor 2 in terms of a direct current but are coupled in terms of a high frequency and which form a closed circuit in terms of a high frequency; and a resistor 4 is provided which connects the circuits in which phases of the voltage standing waves are different by nearly 180 deg. in the plurality of circuits. As the coil and the circuits are coupled by a high frequency, a high-frequency current flows in the resistor, and the resonance impedance of the choke coil can be lowered. As a result, the transmission-amount frequency characteristic of a transmission line using the choke coil can be improved.

Filed: 1985-11-28
Abstract: PURPOSE:To obtain superior ohmic contact, by piling an Al film as an wiring layer and then doping a surface of the Al film with Si ions to decrease an amount of Si deposited at a contact part. CONSTITUTION:After a contact hole 4 is selectively opened on an insulating film 3 so that it corresponds to a diffusion region 2, an Al film 7 is piled on an insulating film 3 containing the contact hole 4 and the upper surface is doped with Si ions 8 from above. When heat treatment is performed thereafter, the Al film 7 turns into an Al Si film by the doping Si ions 8, and ohmic contact can be realized between a wiring layer and the diffusion area 2. And, by doping of Si ions 8 at a surface side of the Al film 7, Si precipitates mainly at the surface side of the AlSi film, with precipitation of Si being decreased at the contact part. The same effect appears in either of N-type substrate and P<+> diffusion region, and even in the case of ion implantation of Si ions by an ion-implanting machine.

Title: Clogging detector for dust filter
Inventor: ASANO HIDEO
IPC: B01D46/46
Filed: 1991-09-20
Abstract: PURPOSE:To detect the clogging of a dust filter used for automobile air conditioners, etc., and to give an alarm signal. CONSTITUTION:On the downstream side of two zones of a dust filter 1 arranged in a air duct 2, are installed wind velocity sensors A, B respectively. The output side of the sensors A, B is connected to a comparator 6 whose output side is connected to an alarm device 7, and simultaneously on the upstream side or downstream side of one of the two zones of the dust filter 1, is installed an obstacle 3. In the zone of the dust filter 1 where the obstacle 3 is located, there are less air flow and less quantity of dust stuck than in another zone. Therefore, when the filter is new, the detected air velocity is lower than that in another zone, but when the velocity detected in another zone where clogging is increased is lowered, the former velocity is equal to the latter. Comparing the velocities, the degree of clogging is judged to give an alarm signal.
