Title: Liquid crystal display device
Inventor: YOSHIDA HIDESHI
IPC: G02F1/133
Filed: 1988-07-07
Abstract: PURPOSE:To cause a liquid crystal display device to always make a proper black-and-white display irrespective of temperature changes by providing mat- like transparent electrodes, a temperature detecting means, and a voltage generating means which generates a voltage corresponding to the temperature of the device and applies the voltage across the transparent electrodes to a liquid crystal panel for compensation. CONSTITUTION:This liquid crystal display device has a two-layer structure of a liquid crystal panel 20 for display and liquid crystal panel 21 for compensation. The panel 21 is provided with mat-like transparent electrodes 22a and 22b, a temperature detecting means 23 at a position at which the temperature of the device can be detected, and a voltage generating means 24 which generates a voltage corresponding to the temperature of the device detected by the means 23 and applies the voltage across the electrodes 22a and 22b. Therefore, when the voltage is applied across the electrodes 22a and 22b, the liquid crystal molecule of the panel 21 stands and the compensating action at the panel 21 becomes less. As a result, the somewhat yellowish white part of the black-and-white display changes to bluish and the quality of the display is improved.

IPC: F24F13/30
Filed: 1993-07-09
Abstract: PURPOSE:To balance flow rates of refrigerants flowing through refrigerant channels of two systems and to enhance a heat exchanging rate by using a smooth tube in the channel having a long channel of the two systems and a grooved tube in the channel having a short channel. CONSTITUTION:An indoor heat exchanger 7 has refrigerant channels 7a, 7b of two systems, and the channels 7a, 7b have a plurality of hair pinlike heat transfer tubes 10 and a U-shaped connecting tube 11. Refrigerant flowing from an inlet 8a reaches an upper part of fins 12 while moving in a zigzag manner and then moves down to flow toward an outlet 9, while refrigerant flowing from an inlet 8b reaches a lower part of the fins 12 and then moves up to flow toward the outlet 9. However, since the lengths of the channels 7a, 7b of the two systems are about 5:4, flow of the refrigerant of the channel 7a side is deteriorated as compared with that of the channel 7b side. Then, a smooth tube having better flow of the refrigerant is used for the tube 10 of the channel 7a side having a long channel, a grooved tube having large contact area with the refrigerant is used for the tube 10 of the channel 7b side having a short channel, and hence flow rates of the flowing refrigerants to the both are balanced.

SOLUTION: A part whose peripheries are mutually opposed is contracted on an inside diametral side so as to be set to a taper part 3a along the inner circumference of the upper end of an inner tube 2 being an axle side tube on the lower end side of a suspension spring 3, and also the upper end side of the suspension spring 3 being a side upper than the taper part 3a is contracted shorter than the base end 3b of the suspension spring 3 being a part lower than the taper part 3a. Therefore, the periphery of the lower end side of the suspension spring 3 is prevented from being brought into contact with the inner circumference of the upper end of the inner tube 2 even under a condition that a front fork is widely contracted so as to buckle the suspension spring 3.  As a result, even when the front fork is contracted at a large stroke, such occurrence that contracting property is impaired and an abnormal noise is generated can be eliminated.
