    摘要: A spreading code generating apparatus carries out M-sequence multiplication and zero value addition of generated orthogonal codes to obtain channel identification codes, and then carries out inverse Fourier transform of the channel identification codes to generate spreading codes and inverse spreading codes. A transmitting apparatus and a receiving apparatus store the spreading codes and the inverse spreading codes generated by the spreading code generating apparatus, respectively, and use a single code respectively selected from the stored codes to carry out spread spectrum communication. With the use of the spreading codes for spreading, the input signal is spread over a wide frequency band with uniform power on the frequency axis. Thus, transmission characteristics are improved, and multiplexing capacity is increased.

    摘要: A starter for engines uses a leaf spring as a shift lever for advancing a pinion gear for engagement with a ring gear. The shift lever may be constructed with a plurality of layered leaf springs having respective front ends spaced apart one another to contact a one-way clutch at different positions. The shift lever may include a lever holder which has a low heat conductive member to minimize fatigue of the leaf spring. The leaf spring is initially loaded with a spring force.

    摘要: A resilient restricting member of a rotation restricting member which restricts a pinion moving body from rotating is accommodated in a frame of a restricting member holder under a flexed and loaded state so that the rotation restricting member has a sufficient rotation-restricting function as long as the rotary force of the pinion moving body does not exceed the load acting thereon at the time of engagement and restriction of rotation. When a pinion gear abuts the end face of a ring gear and the pinion moving body is restricted from moving forward, the entire rotary force of an output shaft acts on the pinion moving body. The resilient restricting member flexes further in the restricting member holder to allow rotation of the pinion moving body, thus enabling the pinion gear to mesh the ring gear. Thus, the rotary force of the output shaft is converted to the advancing force of the pinion moving body surely even when the spiraling of the helical spline is not so large.

    摘要: A method controls a display for a copying machine including a device having two-dimensional dot displaying device in which displaying layers for at least two colors of red and green are provided and capable of displaying at least four colors red, green, white, and black by combining the displaying layers. The method is made up of the steps of providing storing device including a memory space which corresponds to a display of the dot displaying device and in which addresses are sequentially assigned. The system then calculates display information of one-dimensional absolute address position information in response to display information in which coordinate information is made into two-dimensional coordinate information. This display information is stored in the storing device, and then supplied to the displaying device so as to be displayed. The display device is primarily a dot type device.

    摘要: In this signal detection device (100), a delaying unit (101) delays a first distributed signal or a second distributed signal distributed from a received signal for a period of time of T1 to form a first multiplication signal, and delays the one for a period of time of T2 (T2>T1) to form a second multiplication signal. An integrator (104) calculates a first correlation value by integrating the result of multiplying the first distributed signal and the first multiplication signal. An integrator (105) calculates a second correlation value by integrating the result of multiplying the second distributed signal and the second multiplication signal. An evaluation unit (108) evaluates whether the signal to be detected, which is a periodic signal with a period of T1 or a periodic signal with a period of T2, exists or not, on the basis of the first correlation value and the second correlation value.
