Title: Liquid crystal display device
Inventor: KAJIMURA HIDEKI
IPC: G02B1/10
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To obtain the back light of uniform illumination to prevent the problem that a picture is difficult to see by dazzling by providing a polarizing plate on the light source side, which is subjected to such surface treatment that the transmittance is lower only in the vicinity of the light source in comparison with the other part, in the liquid crystal display device whose rear face is arranged with a light source for illumination. SOLUTION: A polarizing plate 31 nearer to two light sources 4 in this liquid crystal display device is subjected to such surface treatment that the light transmittance in parts 3a nearer to light sources 4 is lower than that in parts 3b far from light sources 4. As an example of the surface treatment, it is treated into a polished glass, and parts 3a nearer to light sources 4 is made opaque in comparison with parts 3b far from light sources 4. Since parts 3a nearer to light sources 4 of the polarizing plate 31 nearer to light sources 4 is subjected to the surface treatment in this manner, transmission of light from light sources 4 is suppressed in parts 3a (in the vicinity of the light source part) nearer to light sources 4 to eliminate a conspicuously bright part, and an approximately uniform brightness on the display face is realized economically.

Title: Method for calking clamping member against cable
Inventor: MORI SHIGEKI
IPC: B21F15/00
Filed: 1989-10-05
Abstract: PURPOSE:To prevent the member from slipping by largely deforming the both end parts than the central part of the clamping member and biting the saw- toothed part set at the both peripheral parts in the case of fixing the clamping member of U-letter cross section to the outer cover of the cable with using the calking tool. CONSTITUTION:The clamping member 10 is deformed only at its both end peripheral parts and its saw-toothed parts 14 are bitten in the outer cover 2. So, the central part is deformed comparatively little and the force to press the core wire 3 is also small. Because only the saw-toothed part 14 formed in jigzag type is bitten in the outer cover surface at the both end parts of the clamping member 10, and so the pressing force is not acted to the space between the adjacent saw-toothed parts and the space to escape for the inner core wire is provided. With this constitution the core wire is possible to be prevented from shearing at the calking time. Further if the clamping member moves the cable, the biting amount is increased more and the slipping is prevented.

Abstract: PURPOSE: To realize clamping with an excellent temperature characteristic and high accuracy by setting a negative peak level of a triangle wave signal of an output signal of an integration circuit to a setting potential when a transistor (TR) is conductive by a differentiation signal of a differentiation circuit and obtaining a clamped triangle wave signal to the setting potential at an output of a DC block capacitor. CONSTITUTION: An integration circuit 2 and a differentiation circuit 4 generating a triangle wave signal are connected to an output side of a square-wave signal oscillator 1. The differentiation circuit 4 is made up of resistors R3, R4 and a capacitor C4. When a TRQ1 is turned on by a differentiation signal of the differentiation circuit 4, a negative peak of a triangle wave signal of an output signal of the integration circuit 2 is forcibly set to a prescribed potential and a charge equivalent to a difference between the set potential and a voltage being a half of a peak-to-peak voltage Va is charged in a DC blocking capacitor C2. Thus, a triangle wave signal clamped to the setting potential is obtained at the output side of the capacitor C2. When a load impedance of the clamp circuit is light, no buffer amplifier A1 is required.
