Abstract: An image forming device includes a light emission controller that controls emission of a plurality of types of light emission patterns from a plurality of light sources. The light emission controller emits respective light emission patterns corresponding to the operation. When among the plurality of types of light emission patterns, the preceding light emission pattern overlaps with the subsequent light emission pattern, the light emission controller preferentially emits the subsequent light emission pattern having a delay in the light emission start timing. The light emission controller also emits respective first light emission patterns corresponding to the operation, and emits the second light emission pattern expressing the predetermined operation.

Abstract: An image forming device includes a light emission controller which controls emission of a plurality of types of light emission patterns by a plurality of light sources. The light emission controller emits each light emission pattern in response to a plurality of types of operations performed by an operator with respect to an operation portion. The light emission controller causes a light emission start timing of each of the plurality of types of light emission patterns to be different depending on the contents of the operations. The light emission controller emits first light emission patterns in response to operations performed by an operator with respect to the operation portion, emits second light emission patterns in response to a predetermined operation by the image forming device, and causes the first light emission patterns and the second light emission patterns to be different from each other in light emission end timing.

Abstract: A vacuum valve includes a hermetically sealed vessel having an insulative cylinder, an end plate at a movable electrode end, and an end plate at a fixed electrode end. The vessel accommodates a movable contact and an opposed fixed contact. The movable contact is supported through a bellows allowing the contacts to open and close while maintaining an air-tight (hermetic) seal. The bellows used in at least one embodiment is a seam type bellows without metal plating. Nickel plating layers are formed on the end plate at movable contact end and on a cover, which are joined to the bellows. The ends of the bellows are soldered with the end plate and the cover using a silver solder at the solder joints.

Abstract: There is provided a mobile station that minimizes a pause or a silent period during communication at the time of a reconnection process of communication, thereby to improve the user's convenience and achieve the reduction in the load applied onto the communication network or the mobile station. When an out of synchronization detection unit 4 of a mobile station 2 detects out of synchronization, an individual timer value determination unit 53 selects two or more timer value change triggers from timer value change triggers stored in a timer value change trigger memory 51, and then determines the timer values respectively for the timer value change triggers that have been selected, based upon the determination rules stored in an individual timer value determination rule memory 52. A reconnection timer value calculation unit 54 calculates an appropriate reconnection timer value based upon the two or more individual timer values that have been determined by the individual timer value determination unit 53.

Abstract: A communication device and a communication method capable of implementing high-speed and high-quality communication processing such as handover. A mobile communication terminal is configured such that, in cases where it is judged by a power measurement unit that a reception signal received by a communication unit is equal to or less than a predetermined value, a frequency conversion unit performs computation by expanding a frequency range for performing time/frequency conversion with respect to the received reception signal. Further, a frequency measurement unit measures reception strength of reception signals in the expanded frequency range, and detects a frequency of, among the measured signals, a signal with a reception strength higher than a predetermined reception strength, and the communication unit executes connection processing by using the signal of this frequency.

Abstract: To provide a Cu-Cr alloy electrode material, a mixture of Cu and cr materials at a predetermined ratio is heated until the mixture has been entirely melted, and the molten metal obtained is quenched to precipitate fine Cr particles in a Cu base. Since Cr is melted into Cu before quenching, and then Cr precipitates, Cr particles finer than those in the sintering or infiltration method can disperse in a Cu base. This invention prevents defects such as voids in the structure and the weakening of the fusion of Cu and Cr or failure of Cr to precipitate into the Cu base caused by oxide films on the surface of the Cr particles, thereby providing a fine alloy structure.

Abstract: Interrupting and chopping characteristics of a Cu--Cr contact alloy are improved by rounding Cr particles to be spherical in the alloy. The Cr particles are rounded in the alloy by sintering raw Cr powder particles having an average particle diameter of less than 100 .mu.m at a temperature of 1,100.degree. C. or higher with Cu powder, or by sintering raw Cr powder particles having an average particle diameter of 100 to 150 .mu.m at a temperature of 1,200.degree. C. or higher with Cu powder.
