Abstract: PURPOSE: To make the heat radiation effect of a back illumination source good and to make it easy to maintain the back illumination source by fitting a projection part of a light guide plate in a fitting hole of a circuit board and making the light of the back illumination source incident from the projection part. CONSTITUTION: The projection part 38 as a light guide part inside and outside the circuit board 32 is formed on a light guide body 37 which guides the illumination light of the back illumination source 40 to a display panel 31, this projection part 38 is fitted in the fitting hole 39 formed in the circuit board 32, and the back illumination source 40 is provided for part of the external side of the light guide body 37. When the lamp 40 illuminates, the light reflective material of the lamp 40 reflects the light to emit the light toward the projection part 38 of the light guide body 37, and the projection part 38 serves as the light guide part inside and outside the circuit board 32 to guide the light into the light guide part 37.  This light guide body 37 emits the light to the liquid crystal panel 31 by a light reflective material 42 and a light diffusion plate 41 makes the light uniform to irradiate the entire surface of the liquid crystal panel 31 from behind the liquid crystal panel 31. Consequently, the lamp 40 can be arranged outside the circuit board 32, so the maintenance and replacement of the lamp 40 are facilitated and the heat radiation effect can be improved.

Title: Magnetic head supporting device
Inventor: HOSHINO TAKAMASA
IPC: G11B21/20
Filed: 1990-06-25
Abstract: PURPOSE:To prevent load from being changed to the medium of a magnetic head by the speed of loading the medium by fitting a spring board while inclin ing it so as to get a prescribed angle under the recording face of the recording medium. CONSTITUTION:A medium 8 is held by a magnetic head 1 and a magnetic head 1a opposed to this head 1 therebetween, and pressing load is generated through a magnetic head supporting body 2 by a spring board 4 fitted while being inclined so as to get an angle theta under the horizontal face of the medium. Therefore, it is not necessary to generate the load for pressing the magnetic head to the medium by using a torsion soil spring or a compressing spring, and since friction is not generated at the contact point between the torsion soil spring and the magnetic head to the supporting body, the load is not changed in the case of pulling up and down the magnetic head supporting body. Thus, there is no problem that the load is changed for pressing the magnetic head to the medium 8 by the speed of loading the medium 8.

Title: Friction type continuously variable transmission
Inventor: KASAGI TAKAO
IPC: F16H15/52
Filed: 1987-07-06
Abstract: PURPOSE:To provide the condition of speed change ratio completely zero by forming a chamfering at a point where the speed change ratio on No.3 transmission surface of a planet rotor becomes under a specified range, and by disengaging No.2 transmission surface from the output disc when this chamfering comes in engagement with a transmitting ring. CONSTITUTION:A planet rotor 12 rotates round axes of an input shaft 1 and an output shaft 3, so that centrifugal force acts in the direction of disengaging No.2 transmission surface 14 from an output disc 4. On No.3 transmission surface 15 a chamfering 15a is provided at a point where the transmission efficiency sinks abruptly, i.e. where the speed change ratio becomes below 0.15-0.05. Accordingly the planet rotor 12 inclines a little when the chamfering 15a engages with a transmission ring 16, and No.2 transmission surface 14 is disengaged from the output disc. Thus stable condition with the speed change ratio completely zero can be obtained in the low speed change ratio range with low transmission efficiency. Transmission of the torque to the output disc 4 is made zero completely, and the frictional engagement parts are prevented from wear and/or seize.
