Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent causing the complication of a manufacture process and the increase of equipments by using the photosetting resin of a light trigger type, which starts setting by the irradiation of UV light and successively accelerates setting even when the UV light is interrupted thereafter, for a seal material. SOLUTION: The seal material 6 is formed at a display area peripheral part on a light shielding substrate 2a where a color part 3 is formed and a spacer 8 is uniformly applied on the light shielding substrate 2b where a TFT part 7 is formed. Then, as soon as the light shielding substrate 2a where the seal material 6 is formed and the light shielding substrate 2b where the TFT part 7 is formed are stuck together, the UV light is instantaneously irradiated from the side of the light shielding substrate 2b where the TFT part 7 is formed to set the seal material 6. When the photosetting resin of an epoxy group with excellent strength and flexibility is used as the seal material 6, the environmental resistance of this liquid crystal display element is improved. Thus, the degradation of an oriented film by the irradiation of the UV light is not caused.

Title: Circuit for preventing application of erroneous voltage
Inventor: SAITO SUSUMU
IPC: H02J1/00
Filed: 1991-12-25
Abstract: PURPOSE:To protect an electronic appliance from being applied with a high voltage even if a high voltage supply cable is connected inadvertently with the low voltage input section of the electronic appliance by detecting the voltage level to be fed to the electronic appliance and then switching a relay for feeding power to the electronic appliance. CONSTITUTION:When +12V voltage is applied between terminals 1, 2 and the voltage E1 reaches 4.5V at time t1, an NPN transistor(Tr) Q2 is turned ON to feed a current through the coil of a relay RL2 thus closing the contact r12 thereof. When the voltage E1 reaches 5.5V at time t2, TrQ1 turns ON to feed current through the coil at a relay RL1 thus opening the contact r11 thereof. Consequently, the Tr Q2 is turned OFF to interrupt current supply to the coil of the relay RL2 thus opening the contact r12 thereof. Since the contact r11 is closed until time t2, voltage applied between terminals 3, 4 is outputted as it is but the output voltage does not reach a level (about 7V) for breaking down the logic circuit in an electronic appliance. When the contact r11 is opened, the voltage between the terminals 1, 2 is not outputted to the terminals 3, 4.

Title: Electrophotographic toner
Inventor: MATSUMOTO TAKATSURU
IPC: G03G9/08
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To obtain electrophotographic toners having excellent low temperature fixability by incorporating a specific amount of the gum selected from at least one of gua gum, dammar gum or copal gum into the toners. SOLUTION: The gum selected from at least one of the gua gum, dammar gum or copal gum is incorporated at 0.5 to 15 wt.% into the toners. As a result, the low temperature fixability may be improved without lowering the glass transition temperature Tg of this composition. This improvement is probably achieved by the improvement in the affinity of the functional group in the gua gum, dammar gum or copal gum and paper and the lowering of the melting initiation temperature of the toners by the addition of these additives. The amount 0.5 to 15 wt.% (more preferably 2 to 15 wt.%) of addition is a range where (a preservable property is maintained) and the fixing temperature is widened to a lower limit direction without largely lowering Tg. These additives are added to the composition in the production stage of a binder resin or in the production stage of the toners.
