14 Dec 2011TL;DR: In this paper, a zoom lens system with negative power, positive power, negative power and positive power was presented, where the first lens group, second lens group and third lens group move along the optical axis.
Abstract: This zoom lens system is provided with: a first lens group that has negative power; a second lens group that has positive power; a third lens group that has negative power; and a fourth lens group that has positive power. During zooming, the first lens group, second lens group, and third lens group move along the optical axis. During focusing, the third lens group moves along the optical axis. The zoom lens system satisfies the conditions: 2.5 ≤ | (1 - (β 3T ) 2 ) × (β 4T ) 2 | ≤ 7.0 and 0.5 ≤ Bf W /f W ≤ 4.0 (β 3T being the lateral magnification of the third lens group at an infinite object distance at the telephoto end; β 4T the lateral magnification of the fourth lens group at an infinite object distance of the telephoto end; Bf W the back focus of the entire system at the wide angle end; and f W the focal length of the entire system at the wide angle end).

01 Apr 1997TL;DR: A solid electrolytic capacitor is composed of a pair of electrodes and a dielectric film there between, wherein one electrode includes a conducting polymer doped with a polyvalent anion and a monovalent one as mentioned in this paper.
Abstract: A solid electrolytic capacitor is composed of a pair of electrodes and a dielectric film therebetween, wherein one electrode includes a conducting polymer doped with a polyvalent anion and a monovalent anion. The conducting polymer layer may have a multi-layer structure wherein a second or third conductive polymer layer is made of doped thiophene or derivative thereof.

06 Jul 2000TL;DR: In this paper, a group key management system and method for providing secure many-to-many communication is presented, which employs a binary distribution tree structure and employs a unique binary ID associated with the corresponding leaf node to which the first member is assigned.
Abstract: A group key management system (20) and method for providing secure many-to-many communication is presented. The system (20) employs a binary distribution tree structure (26). The binary tree (26) includes a first internal node having a first branch and a second branch depending therefrom. Each of the branches includes a first member (22, 22a) assigned to a corresponding leaf node. The first member (22, 22a) has a unique binary ID (24) that is associated with the corresponding leaf node to which the first member (22, 22a) is assigned. A first secret key (28) of the first member (22, 22a) is operable for encrypting data to be sent to other members (22, 22a). The first member (22, 22a) is associated with a key association group (33) that is comprised of other members (22, 22a). The other members (22, 22a) have blinded keys (30). A blinded key (30) derived from the first secret key (28) of the first member (22, 22a) is transmitted to the key association group (33). Wherein, the first member (22, 22a) uses the blinded keys (30) received from the key association group (33) and the first secret key (28) to calculate an unblinded key of the first internal node. The unblinded key is used for encrypting data that is communicated between members (22, 22a) located on branches depending from the first internal node.

10 Dec 2004TL;DR: In this paper, a transmission condition setting/managing part (404) for extracting, from received non-A/V data or A/V Data, at least one of A/VM data billing information, reproduction control information, and copy control information and for producing, from the extracted information, encryption mode information indicative of an encryption mode that is a condition when A/v data are transmitted; an encrypted data producing part (406) for producing encrypted data by encrypting, based on transmission condition as decided by a combination of input terminal information, data format information and attribute
Abstract: A packet transmitter apparatus capable of transmitting, by use of widely utilized packets such as IP packets and the like, contents protected by content protection technologies such as DTCP and the like. There are included a transmission condition setting/managing part (404) for extracting, from received non-A/V data or A/V data, at least one of A/V data billing information, reproduction control information and copy control information and for producing, from the extracted information, encryption mode information indicative of an encryption mode that is a condition when A/V data are transmitted; an encrypted data producing part (406) for producing encrypted data by encrypting, based on a transmission condition as decided by a combination of input terminal information, data format information and attribute information, the received A/V data and further by adding, to the encrypted A/V data, an encryption information header based on the encryption mode information; and a packetizing part (403) for producing a packet by adding a packet header to the produced encrypted data.

02 Mar 1992TL;DR: In this paper, an electrical insulating substrate, an electrode system including at least a working electrode and a counter electrode, a reaction layer including the enzyme provided on the electrode system and a hydrogen ion concentration control layer, and the reaction layer is in contact with the electrodes.
Abstract: The biosensor of the present invention quantifies a substrate contained in a sample liquid by reducing electron acceptors using electron generated in a reaction of the substrate to enzyme and then by measuring the reduced amount of the electron acceptors electrochemically. The biosensor has an electrical insulating substrate, an electrode system including at least a working electrode and a counter electrode, a reaction layer including the enzyme provided on the electrode system and a hydrogen ion concentration control layer, and the reaction layer is in contact with the electrode system. According to the present invention, the hydrogen ion concentration in the sample liquid can be made most appropriate in accordance with the type of the enzyme contained in the reaction layer, without the adjustment of the hydrogen ion concentration in the sample liquid beforehand. Thus, the specific substrate contained in the sample liquid can be easily quantified with accuracy and speed.
