Abstract: A semiconductor memory device has a plastic package including an inductor, a first memory chip including a booster circuit that boosts a voltage from a first voltage to a second voltage using the inductor, and a second memory chip having a terminal supplied with the second voltage from the first memory chip.

Abstract: A memory chip unit includes a pad electrode including first and second portions, and a memory cell array. A prober includes a probe card and a movement mechanism. The probe card includes a probe electrode to be in contact with the pad electrode, and a memory controller electrically coupled to the probe electrode and executes reading and writing on the memory cell array. The movement mechanism executes a first operation that brings the probe electrode into contact with the first portion and does not bring the probe electrode into contact with the second portion, and a second operation that does not bring the probe electrode into contact with the first portion and brings the probe electrode into contact with the second portion.

Abstract: Alloy compositions, structures, and production methods for an appropriate slit cut surface shape improve productivity by increasing welding speed and stabilizing quality during high speed welding in Ti-containing Fe—Ni—Cr alloy production. The Ti-containing Fe—Ni—Cr alloy contains, hereinafter in weight %, C: 0.001 to 0.03%, Si: 0.05 to 1.25%, Mn: 0.10 to 2.00%, P: 0.001 to 0.030%, S: 0.0001 to 0.0030%, Ni: 15 to 50%, Cr: 17 to 25%, Al: 0.10 to 0.80%, Ti: 0.10 to 1.5%, N: 0.003 to 0.025%, 0: 0.0002 to 0.007%, Fe as a remainder, and inevitable impurities, and when the number and size of titanium nitrides contained in material are evaluated in a freely selected field of view of 5 mm2, the titanium nitrides having sizes of not more than 15 ?m are not less than 99.3% of total of the titanium nitrides.

Abstract: Provided is a method for manufacturing a micropore filter usable as SCE. Stainless steel particles having particle diameters of 3 to 60 ?m are subjected to milling in a bead mill using zirconia beads to prepare powder having a flakiness of 0.03 to 0.4. The zirconia adhered to the surface of the powder is removed by pickling. A load of 10 to 15 kN is applied to 0.5 to 1.0 g of the pickled powder, thereby compacting the powder into a columnar compact body. The compact body is kept and fired in a vacuum atmosphere of 10?5 to 10?3 Pa at a temperature of 1000 to 1300° C. for 1 to 3 hours to form a sintered body. The sintered body is pressed into a pipe having an inner diameter of 0.90 to 0.99 times of the outer diameter of the sintered body, and extruded to obtain a micropore filter.

Abstract: In a motorcycle including a screen, a meter panel is arranged at the vehicle front of a rider, and a visor is arranged at the vehicle front of the meter panel. The visor is higher than the meter panel to form an air intake for taking in traveling wind between the visor and the meter panel. A duct extends to a rear side of the screen from the air intake at the vehicle rear of the visor, so that the duct can introduce traveling wind to the rear side of the screen.

Abstract: A directional antenna device for receiving a radio wave in a microwave band transmitted from a communication unit provided on a movable mobile body, by using an antenna unit having directivity and provided on a fixed body fixed to a predetermined position. The antenna unit includes: a plurality of directional antennas arranged with directivities in different directions; and reception selection unit for selecting one of the plurality of directional antennas arranged in the transmission direction in which the radio wave reaches the fixed body, thereby receiving the radio wave. Thus, it is possible to provide a directional antenna device capable of performing stable transmission and reception without being affected by the relative position between the mobile body and the fixed body.

Abstract: A flat cathode-ray tube includes a three-component structure of a front panel, a screen panel, and a funnel which are jointed by frit paste. The funnel is inwardly projected from the front panel and the screen panel in the horizontal direction to form a level-difference portion for storing fused frit over the whole inner periphery of the joint surface, whereby occurrence of defected sealing can be decreased, and occurrence of resultant air leakage can be decreased.
