    • A semiconductor light emitting device which allows part of an active layer to generate light by supplying current to the part of the active layer is disclosed. The semiconductor light emitting device includes: a semiconductor substrate having upper and lower surfaces, the upper surface having a stepped portion, the stepped portion dividing the upper surface into at least a first area and a second area; a current confining layer, formed on the upper surface of the substrate, the current confining layer being discontinuous at the stepped portion, the current flowing through an area between the first area and the second area of the substrate; a multilayer structure formed on the current confining layer, the multilayer structure including the active layer; a first electrode which covers only part of an upper surface of the multilayer structure; and a second electrode formed over the lower surface of the substrate. In the semiconductor light emitting device, the light generated from part of the active layer is extracted to the outside through a portion of the upper surface of the multilayer structure which is not covered with the first electrode.

    • A vehicular anti-lock control system includes: a ground load calculation section for detecting or estimating a ground load of a wheel; a road surface friction coefficient calculation section for detecting or estimating a road surface friction coefficient; and a reference fluid pressure calculation section for calculating an upper side reference fluid pressure and a lower side reference fluid pressure in anti-lock control based on the ground load and the friction coefficient. The upper and lower side reference fluid pressures are respectively determined to be an upper limit value and a lower limit value of a fluid pressure in anti-lock control. Therefore, it is possible to suppress the amount of change in the fluid pressure during anti-lock control, thus improving the braking effect and the braking feel.
    • 车辆防抱死控制系统包括:地面载荷计算部分,用于检测或估计车轮的地面载荷; 用于检测或估计路面摩擦系数的路面摩擦系数计算部; 以及参考流体压力计算部分,用于基于地面载荷和摩擦系数计算防抱死控制中的上侧参考流体压力和下侧参考流体压力。 上下参考流体压力分别被确定为防锁控制中的流体压力的上限值和下限值。 因此,可以抑制防抱死控制期间的流体压力的变化量,从而提高制动效果和制动感觉。

    • A portable telephone apparatus 100 according to the present invention comprises a call waiting section and a telephone number acquisition section that can acquire telephone numbers of telephone apparatuses on the other end of lines. A telephone directory information registration section 109 registers telephone numbers associated with information on names. A caller confirmation section searches a telephone number of the telephone directory information registration section 109 based on the telephone number acquired by the telephone number acquisition section and confirms the caller. A character string speech conversion section converts the character information on the name of the confirmed caller to speech information. A caller information notification section notifies the user of the speech information from the character string speech conversion section when an incoming call arrives during a call with speech at a volume level which does not disturb the call.
    • 根据本发明的便携式电话装置100包括可以获取线路另一端的电话设备的电话号码的呼叫等待部分和电话号码获取部分。 电话簿信息登记部分109记录与名称信息相关联的电话号码。 呼叫者确认部分根据电话号码获取部分获得的电话号码来查询电话号码信息登记部分109的电话号码,并确认呼叫者。 字符串语音转换部分将所确认的呼叫者的姓名的字符信息转换为语音信息。 来电者信息通知部分在来电不在呼叫的音量级别的语音呼叫期间到来时,从字符串语音转换部分向用户通知语音信息。
