摘要： A sheet conveyer device including a sheet container tray and a guide member to restrict a position of edges of the sheets is provided. The sheet container tray includes a first engagement section. The guide member includes an arm part and a first engageable part being engageable with the first engagement section. One of the first engagement section and the first engageable part is formed to have a concave structure, and the other one of the first engagement section and the first engageable part is formed to have a convex structure. A first plane in the concave structure, which becomes slidably in contact with the convex structure when the guide member is moved in a pointing direction, is formed to incline in a more moderate angle than an angle of a second plane in the concave structure, which becomes separated from the convex structure.

摘要： The present invention aims to provide a radio base station that has equivalently high reception sensitivity without increasing the number of antenna elements while keeping the utilization efficiency of time slots high. The radio base station comprises a radio unit 101 and a radio unit 102. Two time slots, one at each radio unit, are allocated to a mobile station. After a signal transmitted from the mobile station is received and demodulated, a piece of data received by the radio unit 101 is compared with a piece of data received by the radio unit 102 so that one of the pieces of data that has fewer errors is selected.

摘要： An RF circuit (131–138) satisfies Pnoise+NF+G≦Plim+sW (0≦s≦4) at an edge of a guard band with respect to a required transmission level PAll, an upper tolerance level of out-of-band noise Plim, a guard bandwidth W, and a noise level Pnoise, where NF is a noise figure and G is a gain. An IF circuit (121–123) satisfies PAll≦Pin+G, where PIF is an output level of a BPF (123). Out-of-band noise levels are reduced to Pnoise by the steep BPF (123). The RF circuit (131–138) is structured so that noise from a local oscillator circuit (134) does not surpass noise from the IF circuit (121–123). Reductions in power consumption are thus realized in addition to guard bandwidth reductions, because of being able to eliminate out-of-band noise from an amplifier (138) using a low-loss filter (140) having an attenuation slope s.
摘要翻译： 射频电路（131-138）在保护频带的边缘相对于所需传输电平PAll满足Pnoise + NF + G <= Plim + sW（0≤s≤4），上限公差电平 带宽噪声Plim，保护带宽W和噪声电平Pnoise，其中NF是噪声系数，G是增益。 IF电路（121-123）满足PAll <= Pin + G，其中PIF是BPF（123）的输出电平。 陡峭的BPF（123）将带外噪声水平降低到Pnoise。 RF电路（131-138）被构造成使得来自本地振荡器电路（134）的噪声不超过来自IF电路（121-123）的噪声。 由于能够使用具有衰减斜率s的低损耗滤波器（140）能够消除来自放大器（138）的带外噪声，因此除了保护带宽降低之外，还实现功耗的降低。
