摘要:
A gain control section (150) controls an attenuator (101) to change the level of a signal output from the attenuator (101) to variable amplifiers (121, 131) and at the same time controls the variable amplifiers (121, 131) to adjust the gains in the variable amplifiers (121, 131). Through this adjustment, the gain control section (150) determines the respective gains in such a way that a lower limit value of the detection range of a detector (122) matches an upper limit value of the detection range of a detector (132). A detection circuit 100 having such a configuration can easily expand a dynamic range and fully realize an AGC function while preventing deterioration of the detection accuracy attributed to characteristic variations of devices such as amplifiers and detectors.

There is an input key section is provided in the opposed surface of the main body section meeting the cover section when the device is folded. There is the main display section provided in the opposing surface of the cover section meeting the main body section when the device is folded. Because of this, the electronic device can be used easier as a mobile phone. Furthermore, the electronic device also can be used easier as a still camera because the device can be used as a still camera immediately whenever the user wants to, even when the electronic device is in stand-by mode of mobile phone mode.

A method of increasing helical twisting power (HTP) in an optically active compound used in a liquid crystal material is provided. An optically active compound which exhibits a large HTP value is also provided. Furthermore, a liquid crystal composition which exhibits a high upper temperature limit of the liquid crystal after the addition of the optically active compound, and a liquid crystal display device using the same are provided. In a method, an HTP of a compound having a partial structure represented by formula (A), which has an asymmetric carbon atom, is increased by replacing the partial structure represented by formula (A) by a partial structure represented by formula (B) (wherein * represents the position of an asymmetric carbon atom, Y1 represents a substituent such as an alkyl group and a halogen). A compound is represented by formula (I):

A limited output color group generation section generates in advance, from a group of input colors (limited input color group) satisfying a constraint condition set in an input color space in advance, a group of output colors (limited output color group) in an output color space corresponding to the input colors. An input color element determination section determines at least one element of input colors satisfying the constraint condition using the limited input color group and the limited output color group. Since the limited input color group and the limited output color group satisfy the constraint condition, at least one element of the input colors satisfying the constraint condition can be determined easily.

Drivers which are resiliently biased to leaf members bring portions to be pushed and slide operating portions thereof into resilient contact with pressing projections of a manipulating knob and conductive plates respectively and hence, when the portions to be pushed are pushed by the manipulating knob, the slide operating portions slide on the conductive plates. Further, contact positions between the slide operating portions and the conductive plates in a non-loaded state in which the manipulating knob is not present is set by preliminarily considering that the drivers are slightly rotated when the manipulating knob is mounted in a preloaded state. Accordingly, the portions to be pushed are slightly elevated when they are pushed by the manipulating knob.

The invention provides a supporting mechanism of a slide door in which a lower end rail portion being most easily dirty in a slide door opening and closing portion is hardly get dirty and an operation can be smoothly and without being shaky performed even when a great load is locally applied to the slide door at a time of moving the slide door. The supporting mechanism of the slide door has upper and lower rails extending along edge portions of upper and lower ends of the entrance/exit and guide rollers respectively provided at least in upper and lower end portions of a front edge of the slide door. The lower rail is constituted by one narrow plate rail having a lower end edge being a free end, the lower guide rollers include a set of two or more rolling rollers, and the set of two or more rolling rollers hold and support the lower rail therebetween from below so as to freely roll. Accordingly, even when a local external force is applied at a time of opening and closing the slide door so as to generate a little deformation, it is possible to smoothly open and close the door without being shaky. Further, since a portion where the lower rail is placed has no room where the earth and sand are accumulated, the rail is not clogged by the earth and sand after a long time use, so that it is possible to secure a smooth opening and closing operation.
摘要:
Despreading means 10 despreads a pilot signal included in a first received signal 1. Strength determination means 15 determines the strength of the despread pilot signal. Integration control means 16 determines the integration interval used by integration means 13, from the strength of the received pilot signal. The differences in strength detected by strength difference detection means 12 are added together by the integration means 13 over the period of time decided by the integration control means 16. The integration interval used by the integration means 13 is made changeable according to the receiving environment. Accordingly, when there is the superior receiving environment, there is reduced the load imposed on the integration means 13 when the integration means 13 performs the processing operations. Therefore, there can be realized a superior CDMA receiver phase tracking system which dissipates a fewer amount of electric power.
