The presented invention provides methods and apparatus to generate a efficient medium dedication schedule which give wireless medium the ability to serve real-time and non real-time application concurrently and still be able to maintain the QoS as requested by real-time application. Furthermore, it also presents methods for implementing buffer in an efficient matter in order to complement the advantage introduced by burst transmission and burst acknowledgement.

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.

An image reading apparatus includes a line sensor for reading an image of an original, a scanning optical system that has a light source and scans the original, a reference reflection member provided in such a position as to reflect a light emitted from the light source, a buffer memory for storing data of the image, an intermittent reading part interrupting and restarting scanning performed by the scanning optical system based on a residual storage capacity of the buffer memory, and a light amount variation correction part correcting a variation in an amount of light of the light source during an interruption of the scanning based on an amount of reflected light from the reference reflection member.

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.

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.

In a starter for an engine, a magnet switch attracts a plunger by a magnetic force generated by a solenoid coil wound around a sleeve, so that a pinion fitted on an output shaft of a starter motor is driven by movement of the plunger to engage with an engine ring gear. The the plunger is pressed to contact tightly with the sleeve, whereby the relative movement between the plunger and the sleeve is restricted as long as the coil is held deenergized. The pressing may be attained by an inclined surface provided on the plunger or a flexture of a transmitting member which connects the plunger and a pinion.

In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, an unstabilizing agent is provided to the image holding member. An attaching state between the image forming substance and the image holding member stably attaching the image forming substance on a surface thereof is changed to an unstable state by the unstabilizing agent. The image forming substance is separated and removed from the image holding member by making a separating member come in close contact with the image forming substance on the image holding member having the provided unstabilizing agent. A processing situation mark showing a processing situation of removal of the image forming substance is formed in the image holding member. The processing situation mark can be removed from the image holding member by the image forming substance removing processing.

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.

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.
