Patent JP-H0296330-A (JP)
Title: Manufacture of semiconductor device
Inventor: TABUCHI SHUJI
IPC: H01L21/266
Filed: 1988-09-30
Abstract: PURPOSE:To exfoliate a photoresist as a mask material with ease with wiring resistance lowered by ion implantation with impurity ions of high does by exposing a wafer patterned with the photoresist and thereafter subjecting the wafer to ion implantation. CONSTITUTION:After a wafer 1 patterned with a photoresist 2 is exposed to ultraviolet rays 4 to hot heat, impurity ions 5 are doped into the wafer 1 using the photoresist 2 as a mask material. Since the photoresist 2 is hardened by exposing it to the ultraviolet rays 4, the photoresist 2 is difficult in its modification by the ion implantation even the ion doping is performed in the foregoing condition and hence removal of the photoresist 2 after the ion doping is facilitated. Hereby, wire resistance is reduced by ion doping of the impurity of high dose and at the same time photoresist 2 as a mask material can easily be exfoliated upon the ion implantation.

Title: Y/c separation filter
Inventor: KONDOU TETSUJIROU
IPC: H04N9/78
Filed: 1983-12-27
Abstract: PURPOSE:To ensure the Y/C separation with high accuracy and to improve the separation accuracy of a filter by setting a two-dimensional area for each prescribed picture element data of an input color video signal and comparing plural picture element data with each other within the two-dimensional area to sort patterns. CONSTITUTION:A digital composite color video signal given from an input terminal 11 of a digital color video signal is supplied to a two-dimensional data extracting circuit 2 of a Y/C separation filter. The circuit 2 extracts the line of the present picture element data to be processes as well as the lines before and after said line of the present picture element data. The output of the circuit 2 is processed by one-dimensional steady property detecting circuits 6 and 9, one-dimensional Y/C separation circuits 7 and 10, etc. At the same time, the output of the circuit 2 is applied to a two-dimensional pattern sorting circuit 17, two-dimensional Y/C separation circuits F1-F37 and a subtraction circuit 3. Then patterns are sorted through comparison of plural picture element data carried out within the two-dimensional area for each prescribed picture element data on the input signal. Thus the Y/C separation is attained with high accuracy.

Title: Thermal recording material
Inventor: KOIKE KAZUYUKI
IPC: B41M5/30
Filed: 1985-11-06
Abstract: PURPOSE:To provide a thermal recording material enhanced in developed color density and improved in ground fogging, by specifying the optical surface roughness of a thermal recording layer and the density of the thermal recording material. CONSTITUTION:The optical surface roughness of a thermal recording layer is set to be not more than 6mum, and the density of a thermal recording material is set to be 0.85-1.00g/cm<3>. When the optical surface roughness exceeds 6mum, developed color density is lowered, and it is impossible to obtain a satisfactory developed color density. When the density is less than 0.85g/cm<3>, developed color density is low, and a satisfactory developed color density can not be obtained. On the other hand, to obtain a density of more than 1.00g/cm<3>, the pressure applied to the thermal recording material must be increased, which leads to an increase of fogging.

Title: Carpet having under cushion and forming method of under cushion
Inventor: SUGIMURA HIDEO
IPC: B60N3/04
Filed: 1996-09-02
Abstract: PROBLEM TO BE SOLVED: To form high density by forming a high density part whose density is partially heightened in an under cushion, and pressing and burying it in the timing when a foaming resin raw material of a high density prescribed part is not hardened. SOLUTION: A coating film 21 of a heat resistant resin film or nonwoven fabric is arranged on the reverse 20b of a carpet, and oozing-out of a foaming resin raw material to the carpet side is prevented. Among an under cushion 30, a partial specific area is formed as a high density part 31. Density of this high density part is 0.10 to 0.50g/cm<3> , and the density is higher by two times or more than a general part 32. Particularly, a density change from the general part is sharply caused. A temperature of an upper mold of an injection molding mold is heightened to 50 deg.C or more, and a temperature of a lower mold is cooled to the normal temperature, and foaming reaction is advanced sufficiently faster on the upper mold side (particularly, in an excess part) than the lower mold side. Therefore, on the lower mold side where foaming reaction (hardening and polymerization) is delayed, a foaming cell is intensively compressed by a press from above, and is formed as a high density part whose density is higher than the other part.

Title: Check valve assembly, assembly capable of introducing fluid into iv piping and method for introducing fluid of second fluid supply source into said iv piping
Inventor: FURANKU EMU RITSUCHIMONDO
IPC: A61M39/02
Filed: 1990-09-20
Abstract: PURPOSE: To enable a fluid supply source to be readily connected to fluid circulation piping by providing the assembly with means which project from the bottoms of valve cavities and engage with valve elements to position the valve elements at almost the centers of the insides of valve chambers. CONSTITUTION: A recess 86 formed in a skirt part 80 is disposed to surround a center projection 46 and to be fitted and connected to radial projections 50, 52, 54, 56, so that the bottom edge 88 of a valve element 78 abuts to the bottom 48 of a valve cavity 42. Further, since valve elements 78a, 78b, 78c are arranged to surround the center projection 46, the valve elements can be positioned at almost the centers of the insides of respective valve cavities 42a, 42b, 42c. If the valve element 78b is deformed, one or more of ribs 58, 60, 62, 64 makes contact with the skirt part 80, preventing the valve element 78 from closing an inlet 68 or outlet 70. Thus with a fluid passage 44 kept unclosed, a fluid can simultaneously communicate between a main fluid supply source 12 and a pump 20 and between a fluid supply source 24 and the pump 20.
