摘要:
The present invention provides a technology of effectively avoiding tracing on a terminal performed with an identification number being a target and DoS attack without making any significant changes to a communication system.In the wireless communication system of the present invention, under a control of a control communication processing portion 113 of an access point, a hash function arithmetic operation processing portion 112 generates a third identification number to be updated using a current identification number, hash key and random number for any wireless communication terminal, a control communication processing portion 113 sends an update instruction signal containing the random number to the wireless communication terminal and updates the current identification number stored in the identification number storage portion 121 to a second identification number. When the wireless communication terminal receives an update instruction signal, the current identification number is updated to the second identification number and the hash function arithmetic operation processing portion generates a third identification number using the current identification number, hash key and random number stored in the self number storage portion.

Provided is a photoelectric conversion apparatus for detecting focus, which provides an increased number of ranging points while suppressing a chip-area increase. In a first mode, signals from a first line sensor L1 group are written in a first line memory L1 group while signals from a second line sensor L2 group are written in a second line memory L2 group. In a second mode, signals from the second line sensor L2 group are written in the first line memory L1 group while signals from the first line sensor L1 group are written in the second line memory L2 group, so that even one and the same line sensor can select different ranging point regions, enabling provision of an increased number of ranging points while suppressing a chip-area increase.
摘要:
An apparatus and method for controlling a CVT (continuously variable transmission), and a program for executing the control method that reduces a transmission shock during a braking operation. When a foot brake switch is turned on and a vehicle speed is less than or equal to a threshold speed, the ECU increases a clamping pressure applied to a transmission belt to a pressure level higher than a normal pressure. When the vehicle speed falls to or below the threshold speed when the foot brake switch is turned on, the ECU prohibits an increase in the clamping pressure applied to the transmission belt.

A plurality of light emitting elements 11 are arranged in parallel with a constant pitch to provide a semiconductor laser bar 10. An optical waveguide 20 has a core part 21 for guiding a light emitted from each of the light emitting elements 11 and a cladding part 22 formed around the core part 21. An optical fiber 30 has a core 31 and a cladding 32 formed around the core 31 for confining the light to the core 31. The optical waveguide is bonded to a side surface of the optical fiber 30, and the light emitted from the semiconductor laser bar 10 is inputted to a side surface of the core 31 of the optical fiber 30 via the core part 21 of the optical waveguide 20.

A data wiring is provided on a glass substrate in an active element substrate. For the data wiring, a first portion, extending in a direction that slopes and forms a fixed angle with respect to the rubbing direction of an oriented film, and a second portion, extending in a direction sloping to the opposite side of the first portion are alternately arranged and formed in a zigzag pattern. A convex insulation film is formed in a zigzag pattern to cover the data wiring and a common electrode is formed in a zigzag pattern to cover the insulation film. A shilding layer is formed in a zigzag pattern on an opposing substrate to completely cover the insulation film and does not protrude from the region directly above the common electrode. The high-contrast, multi-domain system in-plane switching type liquid crystal display device obtained with a high numerical aperture and low black brightness.

A draw gear has a drawbar space formed in a rear part of a counterweight of a industrial vehicle. A drawbar is installed in the drawbar space. An upper section positioning portion is provided in the drawbar space for allowing the drawbar to be moved in a first direction in which the drawbar is drawn and also for positioning the drawbar in a second direction opposite to the first direction. A middle section positioning portion is provided in the drawbar space for allowing the drawbar to be moved in the second direction and also for positioning the drawbar in the first direction. A lower section positioning portion is provided in the drawbar space for positioning the drawbar at least in the second direction. An opening is formed at least on an upper side of the drawbar space for allowing the drawbar to be drawn out of the counterweight.

In a mounting structure of a high frequency apparatus, in an outer circumference around terminals connected to a mother board, an enclosed portion, which is brought into contact with the mother board and is enclosed by a ring-shaped convex portion provided in a cover, or an enclosed portion, which is brought into contact with the mother board and is enclosed in a ring shape by a convex portion provided in the cover and extending portions from the frame, are provided. The terminals are electrically shielded by the enclosed portion. Therefore, when a high frequency apparatus is mounted on the mother board, interfering electric waves are prevented from entering into the terminals, and thus favorable performance is obtained.

The present invention provides a carbon black for coloring cement excelling in dispersibility in cement slurry, exhibiting superior adhesion to a cement matrix, and excelling in coloring characteristics and strength, and a method for coloring a cement-formed product using the carbon black. The carbon black for coloring cement is a carbon black in which humic acids are adsorbed on the surface by a surface treatment using an aqueous solution in which the humic acids are dissolved. The carbon black is preferably a carbon black on which humic acids are adsorbed by wet-granulation and drying using an aqueous solution in which the humic acids are dissolved as granulation water. The coloring method includes adding and mixing a water suspension in which carbon black, on which the humic acids are adsorbed, is dispersed in water with cement slurry, or directly adding and mixing carbon black on which the humic acids are adsorbed with the cement slurry, thereby coloring a cement-formed product.
