摘要： An information processing device to which data can be input by the use of a rotary bezel. A pulse-number detection sensor unit 32 and a rotational-direction detection sensor unit 33 read an optical pattern which is formed the rotary bezel to generate series of pulse signals. The pulse-number detection sensor unit 32 and the rotational-direction detection sensor unit 33 are arranged such that a phase difference occurs between the signals of the sensor unit 32 and the signals of the sensor unit 33, so that it is possible to detect the rotational direction of the rotary bezel. A data-signal generating element 81 generates a data signal on the basis of the detected rotational angle and the number of pulses generated by the pulse-number detection sensor unit 32.

摘要： A charger capable of reliably and uniformly maintaining a discharging gap formed in the vicinity of a contact portion between a charging member and a photosensitive member. A charging member 101 is arranged by supporting and fixing both ends of a flexible film 102 by means of support members 103 to 105. The film 102 forms a flexible portion oriented downwardly from fixed ends S1, S2. The film 102 is brought into contact with the member 110 to be charged in a state in which an unsupported side of the film 102 is oriented toward the downstream side in the rotating direction of the member 110 to be charged. Then, the film 102 is brought into contact with the member 110 to be charged in a contact area N, and the radius of curvature of the film 102 in a zone P2 located downstream of that zone N in the rotating direction of the member 110 to be charged becomes smaller than the radius of curvature of the film 102 in an upstream zone P1.

摘要： When the light from an LED (31) is incident to photodiodes (32 and 33) at illuminances (Pa and Pb), respectively, electric currents (ia and ib) corresponding to each illuminance are generated. When external light which arrives through the tissue of a finger is incident to the photodiodes (32 and 33) at an illuminance (Pc), an electric current (ic) is generated. The electric current (i1) (=ia+ic) generated in the photodiode (32) is added to the electric current (i2) (=-ib-ic) generated in the photodiode (33) at a node (X) and the electric current (ic) corresponding to the external light is offset. Since the photodiodes (32 and 33) are attached so that the distances from the LED (31) may be different from each other, the illuminance (Pb) is so extremely lowered that the electric current flowing into an operational amplifier (34) becomes the same as the current (ia) corresponding to the illuminance (Pa). The amplifier (34) generates a pulsating wave signal (Vm) through current-to-voltage conversion.

摘要： PROBLEM TO BE SOLVED: To estimate the capacity of a secondary battery in a simple configuration. SOLUTION: An electronic clock 200 has a conversion table 285. This conversion table 285 has a table that shows the relation of the terminal voltage and the capacity of a secondary battery 220 in each case of not charging, half-duty charging, and full-duty charging. A control circuit 230 estimates the battery capacity from the terminal voltage to display on a display 204 by using the table depending on the case of not charging, half-duty charging, or full-duty charging.

摘要： PROBLEM TO BE SOLVED: To properly control the charging operations of a secondary battery. SOLUTION: A transistor which stops a charging operation, when a voltage of a secondary battery reaches a limiter voltage, and a comparator controlling the transistor is provided, and a voltage corresponding to the charging voltage of the secondary battery is supplied to the input terminal of the comparator. A reference voltage, corresponding to the limiter voltage of the secondary battery, is applied to the other input terminal of the comparator. The reference voltage is supplied by a DAC, and the DAC set value for determining the value of the reference voltages is obtained by taking the variations of the electrical characteristics of the respective elements such as the comparator, etc., into account and is set, when the secondary battery is charged.

摘要： PROBLEM TO BE SOLVED: To more accurately detect rotary direction and angle without being affected by aging. SOLUTION: Since both of the signal transition timing of a first waveform- shaping signal SSUM and that of a second waveform-shaping signal SDIF are used to refer to a signal level mutually when turning a rotary bezel and inputting information, a position detection precision can be improved and the rotary position of the rotary bezel can be detected for securing inputting information. Also, since the first waveform-shaping signal SSUM and the second waveform- shaping signal SDIF that are related each other are mutually referred to, the influence of aging of sensor units 32 and 33 can be reduced.
