Patent JP-H07301645-A (JP)
Title: Electro-optical probe
Inventor: TAMAKI TERUYUKI
IPC: G01R19/00
Filed: 1994-05-09
Abstract: PURPOSE:To suppress the spatial broadening of the electric field influenced by the change of polarization of laser beams so as to prevent the lowering of space resolution by using material with a low dielectric constant along with material with a high refractive index forming a dielectric reflecting multilayer film. CONSTITUTION:An electro-optical probe 1 applied to a voltage measuring device is constituted of an electro-optical crystal 3 formed of ZnSe, for instance, and a dielectric reflecting multilayer film 4 formed on the back face of the electro-optical crystal 3. The multilayer film 4 is formed by alternately laminating material 5 such as Ta2O5 with a high refractive index and a low dielectric constant, and material 6 such as SiO2 with a low refractive index and a low dielectric constant by vacuum deposition or the like. With the low dielectric constant material thus used along with the high refractive index material, reflectance is lowered by several % compared to the one using high dielectric constant material. The lowering of reflectance is related to the lowering of signal strength, but this lowering is smaller than the increase rate of electric field strength penetrating into the crystal 3 by forming the multilayer film 4 of the material with a low dielectric constant. Space resolution can be thereby improved without the lowering of signal strength.

Title: Color display device
Inventor: FUJITA MASANORI
IPC: G02F1/13
Filed: 1982-07-12
Abstract: PURPOSE:To display bright and clear colors and to improve the dichroic contrast of display by providing a display body layer capable of controlling a transparent and a scattering mode to a front surface, and providing a dichroic mirror to its rear surface and a scattering and reflecting plate in clear color further on its back. CONSTITUTION:When the dichroic mirror 4 allows only green light to pass and the display body layer 2 is in scattering mode, part of incident light is scattered and reflected by the layer 2 and the remainder is transmitted. The transmitted light has green light transmitted through the dichroic mirror 4 and purplish red light in complementary color is reflected. This reflected purplish red light is emitted out as scattered light after passing through the layer 2 again. The green light transmitted through the mirror 4, on the other hand, is reflected by the scattering and reflecting plate 7 in clear color and emitted out as scattered light, but it is seen nearly in pink on the whole. When the layer 2 is in transparent mode, the scattered green light prevails over the purplish red light if the panel 1 is viewed from the front, and it is seen in bright green on the whole. The layer 2 uses liquid crystal or ferrodielectric transparent ceramic.

IPC: B29C47/08
Filed: 1992-04-15
Abstract: PURPOSE:To obtain easily a cleaning agent which can remove deposits from a molding machine without cleaning it after disassembly after molding by adding a coarse particulate filler which does not melt at the cylinder temperature, to a thermoplastic resin. CONSTITUTION:This agent is produced by adding 20-40 pts.wt. filler having a mean particle diameter of 1-6mum to 100 pts.wt. thermoplastic resin. Although the thermoplastic resin may be suitably selected according to the relationship between the cleaning agent and the thermoplastic resin to be molded, it is desirably one that is the same as the thermoplastic resin fed after cleaning. Examples of the filler which may be suitably selected ones that do not melt at the cylinder temperature of the machine include carbon black and wood flour. By using the above agent, deposits can be easily removed from a molding machine owing to the added filler that does not melt at the cylinder temperature.
