Title: Temperature controller of on board liquid crystal display device
Inventor: AKASAKA KAZUSHI
IPC: G02F1/133
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To prolong the service life without imparting excessive temp. load to a liquid crystal material even if the operation region of a back light is set high by suppressing the output of a control means of a back light when the temp. in a vehicle room is higher than a prescribed temp. SOLUTION: A temp. sensor 22 disposed in a control section 20 of an air conditioner detects the temp. change in the vehicle room. An interrupt signal output means 21 outputs an interrupt signal on detecting that the temp. in the vehicle room is above the prescribed temp. A back light interrupt control means 11 disposed in the control section 10 of the liquid crystal display device lowers the output of a back light 13 which radiates light to the rear surface of the liquid crystal panel 14 of the liquid crystal display device. As a result, the rising of the temp. of the liquid crystal panel to the temp. exceeding the heat resistance temp. of the liquid crystal material constituting the panel is prevented and the probability of imparting the excess temp. load on the liquid crystal material is lowered even if the operating region of the back light is set high.

IPC: G06F12/16
Filed: 1991-10-31
Abstract: PURPOSE:To more surely check the operation of a parity memory and a parity generating/checking circuit by adding an output selecting circuit for a data memory and the parity memory. CONSTITUTION:An output selecting IC 304 and an output buffer IC 306 are added so as to output the contents of the parity memory 204 to a data bus. In the case of checking the contents of the memory 204, a microcomputer 201 generates a parity data output request signal 102 and turns a parity output signal 101 to 'H'. Thereby an output from the memory 204 is selected as an output from the IC 304. When the microcomputer 201 reads out the contents of the memory 202 in this state the output of the memory 204 are outputted to the bit '0' of a data bus 208 without outputting the contents of a bit '0' stored in the memory 202. Thereby the microcomputer 201 can check the contents written in the memory 204.

Abstract: PURPOSE:To aim at simplifying a drive mechanism, by rotating the drive shaft of a paper feed roller adapted to transmit drive force through an one-way clutch, with the use of the tension force of a drive spring made of a shape memory alloy. CONSTITUTION:A small gear 9 is attached to one end of the drive shaft 6 of a paper feed roller 4 through the intermediary of an one-way clutch 8. A gear 11 meshed with the gear 9 is attached to a fixing pin 10, being integrally incorporated with a pulley 12 which is wound thereon with a drive rope 18 in plural turns, the drive rope having one end connected to a return coil spring 15 and the other end connected to a drive coil spring 17 which is made of a shape memory alloy wire subjected to memory treatment such that it contracts when it is heated at a temperature above a predetermined temperature. When a heating power source 19 is energized, the drive spring 17 is heated and therefore contracts to pull the rope 13, and therefore, the pulley 12 is rotated to rotate the paper feed roller 4. Meanwhile when the power source 18 is deenergized, the rope 13 reversely rotates the pulley 12 under the action of the return spring, but the paper feed rolle 4 is not rotated due to the provision of the one-way clutch 8. Accordingly, it is possible to control the paper feed.
