Title: Liquid crystal display device
Inventor: MORI TAKESHI
IPC: G02F1/1335
Filed: 1990-11-20
Abstract: PURPOSE:To introduce light from a light source without loss by providing a transparent condensing member, having a tilted cross section shape so as to become thicker in a light source side and thinner in a back light light-guide plate side, between an end surface light-entering part of the back light light- guide plate and the light source. CONSTITUTION:Light generated from a light source 13 is reflected and condensed with a reflector 16 to be introduced in a light source side of a transparent condensing member 15. The light proceeds while reflecting between two tilted surfaces to convergedly emerge on a short side end surface on a back light light-guide plate 12 side. The light can almost be reflected on a surface being a light-entering surface by selecting a transparent material having a high refraction factor. The outward leak of the light from these surfaces hardly occurs, and the light, entered from a thicker surface on the light source side, is introduced to a thinner surface on the light-guide plate side without loss, permitting illuminating an end surface of the back light light-guide plate 12.

Abstract: PURPOSE:To obtain stable recording and reproducing characteristics by equipping with a high frequency oscillator supported through a supporting spring by means of a head supporting frame and electromagnetic converting elements to be respectively fixed at both edges of the high frequency oscillator and simultaneously, to the node of an oscillating mode. CONSTITUTION:Electromagnetic converting elements 5A and 5B to record and reproduce the inner circumference and outer circumference areas of a recording medium 1, respectively, are fixed at both edges of a plate-shaped high frequency oscillator 6 and to node 7 of the oscillating mode. A supporting spring 3 supports the high frequency oscillator 6 in the position of the nodal line 7. Consequently, even when the moving speed of the recording medium 1 is zero, or regardless of the degree of the speed, the floating heights of the two electromagnetic converting elements 5A and 5B are always made equal, and further, adverse effects due to the thermal deformations of respective parts and an assembly error can be small small. Thus, the stable recording and reproducing characteristics can be obtained.

Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To allow an AC plug accommodatable in a charger upon rotating to be held in the service position and accommodation position using a simple mechanism and reduce the manufacturing costs. SOLUTION: A housing of a charger is equipped with a bearing 8 to support a rotary shaft 4 of an AC plug and a spring holding part 9 to hold a spring member 7. The AC plug is composed of a rotary base 2, a pair of blades 1, a rotary shaft 4, projection 5, and circuit contacts and arranged capable of rotating 90 degs. between the accommodation position and rising position. The spring member 7 is formed by folding up a rod made of an elastic synthetic resin, and in the condition that the AC plug is in the accommodation position, one end of the spring member 7 abuts to the projection resiliently to make holding. In the rising position 90 degs. rotated from the accommodation position, the other end of the spring member 7 abuts to the projection 5 resiliently to make holding.  A stable sense of clicking is generated by the use of spring member 7 having a small modulus of elasticity, and wear of the spring member 7 is prevented. The number of components of the clicking mechanism is decreased and the assembling process is simplified, and the costs can be reduced.
