A lighting apparatus 10 comprising light sources 12a, 12b for emitting light, a plurality of light reflection portions 20 formed on the reflection side for reflecting light incident from the light sources, and a linear photoconductor 14 for causing the light to exit from the exit side opposed to the reflection side, the planes of the plurality of reflection portions being respectively tilted at angles which converge the light to the human eyes watching. Angles of the light reflection portions are set so that exit angles of light exiting from the linear photoconductor are required angles, whereby the lighting apparatus can have a uniform light intensity distribution. The application of the lighting apparatus can provide a liquid crystal display of good display characteristics.

A light-beam scanning apparatus including a rotatable hologram and a fixed plate, which are provided with diffraction gratings to minimize: either a sum total of values obtained by weighting where a square of an optical path length difference between an optical path of a light flux measured along a principal axis of a light beam incident on and diffracted by a diffraction grating of a rotatable hologram, and incident on and diffracted by a diffraction grating of a fixed plate so as to conduct a scanning and converging on a scanning point on an image formation surface, and an optical path of a light flux measured along a marginal ray distanced from the principal axis; or an absolute value of the optical path difference thereof. Another sum total obtained by weighting requiring minimization is: a square of a sum obtained by adding: an amount of displacement of a light beam convergent on a scanning point on the image formation surface, which displacement is measured along the marginal ray distanced from the principal axis of an incident reconstructing light flux with respect to the principal axis of a phase of the diffraction grating of the rotatable hologram to an amount of displacement of the same light, the displacement measured with respect to the principal axis of a phase recorded on the diffraction grating when the light flux is incident on the fixed plate; or by weighting an absolute value of the sum over every scanning position of the formation surface.

A high-resolution light-beam scanning apparatus utilizing only mass-producible holograms instead of utilizing auxiliary optical systems, and capable of compensating for disadvantages. The light-beam scanning apparatus including diffraction gratings for minimizing either: a sum total of values obtained by weighting a square of an optical path length difference between an optical path of a light flux measured along a principal axis of a light beam incident on and diffracted by a first diffraction grating of a rotatable hologram, and incident on and diffracted by a second diffraction grating of a fixed plate to conduct a scanning and converging on a scanning point on an image formation surface, and an optical path of a light flux measured along a marginal ray distanced from the principal axis or an absolute value of the optical path difference thereof; or a sum total of values obtained by weighting a square of a sum obtained by adding an amount of displacement of a light-beam convergent on a scanning point on the image formation surface, to an amount of displacement of the same light. The displacement measured with respect to the principal axis of a phase recorded on the diffraction grating when the light flux is incident on the fixed plate or by weighting an absolute value of the sum. The weighting is conducted at every scanning position of an image formation surface.

Spherical resin particles having a sharp particle size distribution and a method for producing such particles are disclosed. Resin particles according to this invention contain at least a polyester polymer and a polymer formed from a polymerizable monomer, and have an average diameter (D) of 1 to 500 .mu.m. At least 70% by weight of the particles have a diameter in the range of 0.5 D to 2.0 D. Such resin particles can be produced by swelling polyester-containing seed particles with a polymerizable monomer and then polymerizing the polymerizable monomer in swelled seed particles.

A data relay device relays data between a base station device and a base station control device. The data relay device includes a data transmission time acquiring unit that acquires a data transmission time from when data is transmitted from the data relay device to when the data is received by the data relay device via the base station device, a frame value detecting unit that detects a predetermined frame value from a frame transmitted from the base station control device and stores the data, and a frame transmitting unit that, when the predetermined frame value is detected, after a predetermined time elapses in addition to the data transmission time acquired by the data transmission time acquiring unit after detection, transmits a frame having the same frame value as the detected one to a transmission source of the frame from which the predetermined frame value is detected.
