Publication number: 20100086738Abstract: A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded.

Publication number: 20090124156Abstract: A substrate for artificial leathers composed of an entangled nonwoven fabric made of microfine fibers and a binder resin. At least one surface of the substrate for artificial leathers is a densified layer which is made of the microfine fibers and which is substantially free from the binder resin. The binder resin is impregnated into a portion of the substrate for artificial leathers other than the densified layer. The densified layer prevents the binder resin impregnated into the entangled nonwoven fabric from migrating into the surface of the entangled nonwoven fabric, thereby providing the substrate for artificial leathers having the surface substantially free from the binder resin. The peeling strength between the substrate for artificial leathers and a grain layer formed on the surface thereof is drastically improved because the surface of the substrate for artificial leathers is substantially free from the binder resin.Type: ApplicationFiled: May 22, 2007Publication date: May 14, 2009Inventors: Michinori Fujisawa, Jiro Tanaka, Yoshiyuki Ando, Norio Makiyama

Patent number: 6885234Abstract: A complementary source follower circuit has an N-channel type transistor and a P-channel transistor. The threshold voltage of each transistor is independently controlled by a back bias voltage control circuit so that the input voltage and the output voltage relationship can be made linear without the use of an additional circuit such as a level shifting circuit. Also, power consumption can be reduced when the circuit is in standby mode by using the back bias voltage control circuit to achieve non-linearity. A back bias voltage control circuit can also be used to control the threshold voltage of a transistor in series with a resistance load to reduce power usage.Type: GrantFiled: May 8, 2004Date of Patent: April 26, 2005Inventor: Yoshiyuki Ando
