Title: Method for driving liquid crystal element
Inventor: TANAKA TAKAAKI
IPC: G09G3/36
Filed: 1987-03-10
Abstract: PURPOSE:To obtain the liquid crystal element of high contrast by applying a high frequency AC pulse in a non-selection period to prevent the reduction of contrast in the non-selection period. CONSTITUTION:With respect to a selection period t21, an erase pulse whose voltage absolute value is larger than a negative saturation voltage is applied and the element is turned off in a period t23, and the voltage applied to the liquid crystal element in a period t24 is lower than a positive threshold voltage by voltages applied to a scanning electrode and a signal electrode and the turned-off state is kept. The high frequency AC pulse is applied in a period t25, and the contrast is not reduced and the turned-off state is kept in a non- selection period t22. Thus, the degradation in contrast is prevented.

Title: Temperature controller
Inventor: UMEDA ARATA
IPC: G05D23/19
Filed: 1982-04-05
Abstract: PURPOSE:To perform less-overshoot and less-ripple temperature control all the time by varying control-point temperature according to the temperature of a controlled system in power-on operation and making a rise from the control- point temperature to set temperature constant. CONSTITUTION:When a temperature detecting element 1 detects the initial temperature of the controlled system, a selector 3 for an electric power control starting point sets the control-point temperature T1 on the basis of the detected temperature and when the temperature reaches the temperature T1, an output ''H'' is sent to an AND circuit 5 through a pulse generating circuit 6. An on-off controller 2, on the other hand, generates an output until the temperature reaches the set temperature T0, so on-off control is performed from the temperature T1 to the temperature T0 eventually. After the temperature reaches the temperature T0, the output of the circuit 6 continues, so that temperature is controlled to the set temperature T0 under the on-off control of the controller 2.

Title: Character recognizing device
Inventor: ARIYOSHI SHUNJI
IPC: G06K9/34
Filed: 1988-03-11
Abstract: PURPOSE:To obtain an appropriate recognition result even when a word which is not registered in a word dictionary has appeared by defining a degree of coincidence for giving a degree of collation for collating the word, rejecting a result of word collation when a value of the degree of coincidence is small and determining a character segmenting device by a similarity value of a result of character recognition in case of a rejection. CONSTITUTION:An image is inputted by a scanner 1, and from its image, each character is segmented by a character segmenting part 2. The segmented character is collated with a recognition dictionary 4 and a character recognition is executed by a character recognizing part 3, and the first rank - the m-th rank of a result of character recognition are outputted. The result of character recognition is collated with a word dictionary 6 in a word collating part 5, and as a result, a word of the highest degree of coincidence is outputted. In case of the word which has been registered in the word dictionary, a high degree of coincidence is obtained, therefore, as a result of word collation, a character segmenting position is determined, and in case of the word which is not registered in the word dictionary, since the degree of coincidence is low, the character segmenting position is determined by a result of character recognition instead of a result of word collation. As a result, even with respect to an unregistered word, an appropriate recognition result is obtained.
