In construction of a tremolo unit for an electric guitar, a bridge is coupled to a swingable bridge base in an arrangement movable in the string direction and provided with a string hole formed there through, a presser piece is received in the string hole for movement in the string direction, and a lock bolt screwed into the bridge forces the presser piece to press a string to the wall of the string hole with a string bead being locked against the lower end of the string hole. A dual fixing mechanism based on string pressing and bead locking well alleviates damage on the string construction caused by pressure application. The bridge and the presser piece are both made of iron-type metal for improvement in tone color of musical tones generated by the electric guitar.

A liquid crystal layer sandwiched by a lower substrate 1 and an upper substrate comprises cross-shaped supports, a wall surface structure, and a seal member. The supports 15 are provided at the four sides of each pixel. Contiguous pixels are linked via openings between supports. The wall surface structure is provided in the periphery of the supports arranged in the form of a grid. The supports and the wall surface structure are a same member having adhesiveness. A portion of the wall surface structure is an inlet of liquid crystal. A seal member is provided at the perimeter of the wall surface structure 17. The liquid crystal poured from the inlet is poured into all of pixels via openings. A black matrix in the form of a grid, which covers the top side of all of the supports, is provided on the upper substrate.

A method of filling a multilayered cell with media. In the method, a multilayered cell having at least two layers, i.e., a first and second layer, is filled with media. The method comprises forming in the first layer a first medium injection region for filling the first layer with a first medium, forming in the second layer a second medium injection region for filling the second layer with a second medium, the second medium injection region corresponding to a region different from the first medium injection region, superposing the first and second layers, forming within the first medium injection region a first through-hole extending through the multilayered cell in the layer-thickness direction, forming within the second medium injection region a second through-hole extending through the multilayered cell in the layer-thickness direction, and injecting the first and second media into the first and second through-holes, respectively, to fill the first and second layers with the first and second media. Thus, a multilayered cell can be easily produced in a shorter time while attaining a reduction in deterioration during production.

A recording device comprises a display, a photoconductor superposed on the display, and a pair of electrodes disposed on both sides of the display and photoconductor. At least one of the electrodes is divided into sub-electrodes. Information can be written into the recording device by means of light while applying a voltage to each sub-electrode. Therefore, information is not written into part of the recording device corresponding to the sub-element to which no voltage is applied even if extraneous light is applied. As a result a sharp image with no noise can be formed. The recording device also comprises a feed member for applying a voltage to a pair of electrodes of such a recording device, a first light source for writing information in the recording device, and a second light source for reset. Consequently, reset and recording can be done in one cycle.
