A bar code reader has a CCD for producing an image signal, an amplifier for amplifying the image signal from the CCD and a digitalizing circuit for changing the image signal to binary signal. The CCD operates with an operating voltage Vcc less than 8 V. The amplifier has first and second operational amplifiers each having one voltage source terminal connected to Vcc of 5 V and the other voltage source terminal connected to ground. Also, the digitalizing circuit has a third operational amplifier having one voltage source terminal connected to Vcc of 5 V and the other voltage source terminal connected to ground.

In a conduit for a control cable, it is possible to ensure a good rigidity of a stranded portion 3A having a plurality of strand line elements 3 which are wound to an outer surface of the liner 2 without increasing a diameter (8.0 mm or less) of a conduit 1. In order to secure a greater polar moment of inertia of area, a combinatorial relationship between the number (N) of the strand line elements 3 and a diameter (.phi.) of the strand line element 3 is selected from the following group A, B and C. Where A:=.phi.=1.1.about.1.2 mm and N=13, B: .phi.=1.2.about.1.35 mm and N=12, C: .phi.=0.95.about.1.1 mm and N=14.

An amorphous silicon film having a PIN junction inside in parallel to the film surface is formed extending continuously over transparent film electrodes in each plurality of regions being formed and spaced from each other on one main surface of a light transmissive substrate. A laser beam having a wave length covering a substantially ultraviolet rays region and a visible rays region is irradiated from the other main surface side of the light transmissive substrate to an adjacent spacing portion where the amorphous silicon film is to be divided and the amorphous silicon film lying therein is removed, thus the amorphous silicon film is divided into each plurality of regions. An aluminum electrode film is formed continuously covering the amorphous silicon film portions in each region. The laser beam is irradiated from the other main surface side of the light transmissive substrate to the adjacent spacing portion where the aluminum electrode film is to be divided and the aluminum electrode film lying therein is removed, thus the aluminum electrode film is divided in each plurality of regions. The divided aluminum film electrodes are connected to the transparent film electrodes in the adjacent regions, accordingly a plurality of photoelectric converting regions formed on the light transmissive substrate are connected in series.

A content distribution system for transferring contents between transmission device and reception device. The transmission device includes: key obtaining unit that obtains, from reception device, public keys and public key identifiers; watermark embedding unit that embeds a different public key identifier, as electronic watermark, into each of contents that are identical in substance; an encryption unit that encrypts contents using public keys to generate encrypted contents; and transmission unit that transmits encrypted contents to reception device. The reception device includes: key storage unit storing public keys, public key identifiers, and a private key that makes a pair with one of the public keys; key transmission unit that transmits public keys and public key identifiers to the transmission device; content receiving unit that receives encrypted contents from transmission device; and decryption unit that obtains a content from the received encrypted contents, using the private key.
摘要:
A quantum key distribution protocol is provided that reduces the maximum value of the leaked information amount over the same distance when an adversary makes a photon number splitting attack more than the reduction by the BB84 protocol and the SARG protocol, by making use of the advantages of the BB84 protocol and the SARG protocol. By properly proportioning the existing BB84 protocol and the SARG protocol in accordance with the rate determined by the communication distance between the sender and the receiver of the coherent light, a protocol that is more robust against photon number splitting attack than the known existing protocols can be realized, and long distance quantum key distribution, which was not possible until now, becomes possible.
摘要:
An integral skin foam molded article having a core formed with an accommodating recess. An erected wall of the core around the accommodating recess is formed at its intermediate position with a core side step extending perpendicularly to the inner surface of the erected wall so that a bottom side portion of the accommodating recess is narrower than an opening side portion thereof. The skin includes a peripheral erected part with the peripheral erected part of the skin being formed at its intermediate position with a skin side step that is located closer to the opening of the accommodating recess than the core side step of the erected wall, that is extended perpendicularly to the peripheral erected part of the skin, and that is bent toward inside of the accommodating recess. The peripheral erected part of the skin is pressed against the inner surface of the erected wall of the core.
