Title: Illuminating device for liquid crystal display unit
Inventor: TANAKA SHOICHI
IPC: G02F1/133
Filed: 1988-04-26
Abstract: PURPOSE:To directly detect the brightness of a displaying part by comparing a first electrostatic capacity value previously set with a second electrostatic capacity value measured by an electrostatic capacity measuring circuit. CONSTITUTION:A switching circuit 15 incorporates a timer and has such as system that it is reversed and connected to a (b) side by a timer control after a certain time has elapsed since being switched and connected to an (a) side by the control of an electrostatic capacity comparing circuit 13 then a measurement by the electrostatic capacity measurement circuit 12 is executed again. Furthermore, when the electrostatic capacity C of an EL 11 is larger than a reference value C0, the electrostatic capacity comparing circuit 13 does not output a switching controlling signal, but the measurement of the electrostatic capacity C of the EL 11 is continued. And the electrostatic capacity comparing circuit 13 decides whether the electrostatic capacity value C of the EL is C<C0 or C>C0 by means of making a limit electrostatic capacity C0 corresponding to an ambient brightness when the display of an LCD is hard to be seen without an illumination of the EL as a reference value. Thus, a device to automatically illuminate the LCD according to the ambient brightness can be obtained.

Title: Automatic disk changing device
Inventor: KAWAKAMI HIROSHI
IPC: G11B17/22
Filed: 1983-06-13
Abstract: PURPOSE:To improve the disk changing speed and to attain the assured actuation of an automatic disk changing device by making the transfer speed of a rotor transferred along its transfer path less than the transfer speed of a disk whose disk outer circumference is transferred in contact with the rotor. CONSTITUTION:A disk 101 is taken out of a storing part and transferred to a reproduction part through a transfer path. The rotor 352 of a loading unit 307 transfers the disk while it presses the outer circumference part of the disk. The unit 307 advances on guide rails 303 and 304 with revolutions of shift gears 319 and 320. In this case, the peripheral speed of the rotor 352 is increased since the diamter of the rotor is larger than the diameters of gears 319 and 320. Thus the rotor 352 pushes the disk 101 out from its rear side to give a stable transfer to the disk. Therefore, the changing speed of the disk 101 is improved and assured operation is attained.

IPC: B60T8/58
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To directly sense a condition which is to reach or estimated to nearly reach a road surface limitation, when braking operation is carried out by a driver without diverting any attention. SOLUTION: According to arrival at a road surface limitation or estimation of the arrival, a pressure reduction control valve 302 is turned on just before antiskid control is started and, a reaction force to a brake pedal 1 is reduced, so that a driver can sense that it reaches or nearly reaches the road surface limitation and can sense that antiskid control is starting. In addition, the driver need nor pay attention to other parts consciously, so that safety is improved. As information is given by a sense such as a reduction in a reaction force, which predicts reduction in a braking force, the driver can know fear that further intensification of braking operation causes excess of a road surface limitation by intuition.
