Title: Reflector and reflection type liquid crystal display device using the same
Inventor: SATO ATSUSHI
IPC: G02B5/32
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To improve diffraction efficiency (reflectance of external light) and to expand width of diffracting wave length by arranging a reflection layer on a back face of a volume phase transmission type hologram. SOLUTION: If external illumination light 5 is made incident on a liq. crystal display device, firstly only direction of polarized components by the first polarizing film 3 reaches the liq. crystal panel 2 and, after being rotated in accordance with a display pattern through the liq. crystal panel 2, the rotated light reaches the second polarizing film 4. Although light transmitting the second polarizing film 4 is made incident on a reflector 1, the incident light is transmitted without diffracting in the hologram 6 by the angle selectivity, because a liq. crystal panel 2 side of the reflector 1 comprises a volume phase transmission type hologram 6 having angle selectivity. Light 7 transmitting the hologram 6 is scattering-reflected by a speckle reflector 9 on a back face of the hologram 6.  This scattering-reflected light becomes incident light 10 made incident again on the hologram 6, however this incident light 10 is transmitting-diffracted by coinciding with the angle selectivity of the hologram 6.

Title: Search device for faulty part in condenser
Inventor: MURAKAMI KAZUYA
IPC: H01G13/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To search automatically and detect surely a faulty part such as a damaged part of a film in a short time. SOLUTION: A film fed out of a roller 1 is wound around a winding roller 3 via relay rollers 7, between which a light source 4 and a light receiving section 5 are provided. In the event that there is a damaged part in the film passing under the light source 4, light is transmitted through the damaged part, being received by the light receiving section 5. When the light receiving section 5 receives the light transmitted through the damaged part, a controller 8 stops a rotation of a feeding roller 2. Accordingly, the damaged part of the film can be automatically recognized.

Title: Evaporating concentrating device
Inventor: MIURA MICHIO
IPC: B01D1/00
Filed: 1992-09-21
Abstract: PURPOSE:To lower the cost for concentration control of a concentrate and to make the concentration of the concentrate constant even when the concentration of the original solution is changed. CONSTITUTION:This device is provided with a concentrator 1, a steam ejector 2, temperature sensors 3, 6, a solenoid valve 4 for discharging a concentrate and a controller 5.
