Title: Surface acoustic wave element
Inventor: MATSUDA TAKASHI
IPC: H03H9/145
Filed: 1989-11-15
Abstract: PURPOSE:To improve the passing band characteristic by varying the weight of electrode fingers for input and output electrodes per respective unit lengths along its crossing direction. CONSTITUTION:The thickness of electrode fingers 20, 30 is varied by taking the center part of the electrode finger in its longitudinal direction, for example, as shown in the presence/absence of hatched lines. That is, the velocity of a surface acoustic wave propagating in the vicinity of the surface of a piezoelectric base 1 slows down at the comb-line electrode parts with the effect of the mass. Since the wavelength of the wave is constant, the center frequency is changed by a change in the sound velocity when the electrode finger pitchs of the input and output electrodes are constant. Thus, the filters whose center frequency differs slightly from each other is formed by varying the weight per unit length of the electrode fingers 20, 30 along the crossing direction. Thus, the passing band width is widened.

SOLUTION: This polarizing element consists of a laminate formed by successively adhering a polarized light separating film 3 consisting of a cholesteric liquid crystal layer, a quarter-wavelength plate 4 and if necessary, a polarizing film contg. a dichroic material via a tacky adhesive layer 2 having an excellent stress relaxation property and further, the element is constituted, if necessary, by adhering a light transmission plate 1 which has a reflection layer 11 on its rear surface and emits light from the surface to the polarized light separating film 3 side via the tacky adhesive layer 20. Then, the circularly polarized light reflected by the polarized light separating film 3 is converted to the prescribed circularly polarized light while the light is confined between the film and the reflection layer 11 of the light transmission plate and repeats reflection.  The light transmits the polarized light separating film 3 and the unutilized component of the light by the reflection loss is lessened. The reflection loss at the respective boundaries is lessened and the occurrence of the unequal display by the heat from a light source is substantially prevented by the lamination and integration via the tacky adhesive layer 2.

Title: Electrophotographic developing device
Inventor: KOBAYASHI JUNJI
IPC: G03G15/09
Filed: 1985-12-27
Abstract: PURPOSE:To sufficiently crush lumps of toner before they are carried to a developing area, by providing plural developer agitating magnetic members so that they face the peripheral surface of a developing sleeve with a gap, which is narrower than the thickness of a developer layer formed on the peripheral surface of the developing sleeve, between them. CONSTITUTION:Plural developer agitating magnetic members 7 facing the peripheral surface of a developing sleeve 4 are provided above a developer control member 6 in the magnetic developer carrying direction of an arrow (d). The gap between magnetic members 7 and the peripheral surface of the developing sleeve 4 is narrower than the thickness of the developer layer formed on the peripheral surface of the developing sleeve 4. Consequently, the direction of lines of the magnetic force of the magnetic field between a magnetic roll 5 and magnetic members 7 is changed abruptly in a short period in accordance with rotation of the magnetic roll 5. Therefore, a magnetic developer 3 is agitated magnetically between the developing sleeve 4 and magnetic members 7 several times when it is carried to the developing area along the peripheral surface of the developing sleeve 4, and as the result, the magnetic developer 3 receives a relatively large physical force several times. Thus, even lumps of toner having a strong flocculating force are crushed sufficiently before being carried to the developing area.
