Title: Keyboard device
Inventor: SUEDA HISASHI
IPC: G06F3/023
Filed: 1991-11-06
Abstract: PURPOSE:To reduce operation for correcting and erasing a character which is erroneously inputted by reducing input misoperation due to mistyping. CONSTITUTION:A buffer part 2 is stored with key scan data on a key detected by a sensor part 1a and outputs the stored scan data to a decoding part 5 in response to an indication from a discrimination part 4. An arithmetic part 3 analyzes and processes data indicating the degree of contacting of the key detected by the sensor part 1a and sends the result of the analysis or arithmetic to the discrimination part 4. The discrimination part 4 identifies the key having the largest degree of contacting according to the result of the analysis and arithmetic and sends an indication to the buffer part 2 so that the key scan data of the identified key is sent out to the decoding part 5. The decoding part 5 converts the key scan data sent from the buffer part 2 into character code data, which is sent out to a control part 6.

Title: Optical burst transmission/reception circuit
Inventor: TAMURA TAKAFUMI
IPC: H04B10/40
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To require only a narrow light reception dynamic range, to prevent a high speed operation from being requested to the level follow-up ability of a burst signal, to simplify a circuit and to improve ability since the reception levels of a master station side are adjusted almost equal by automatically setting a transmission level in accordance with the distance on a slave station side. SOLUTION: The burst signal from the master station 2 is continuously transmitted to the respective slave stations 1. The respective slave stations 1 receive the burst signals and compare the signal levels with the reference voltage of a comparator. Reference voltage is set to zero voltage with the reception level of the slave station 1b in an intermediate distance as a standard. The slave station 1a in the remote distance outputs voltage in a minus direction and the slave station 1c in the near distance outputs voltage in a plus direction in accordance with the respective distances. A level control circuit converts a signal into a level control signal for setting the transmission level corresponding to the distances based on the output voltage of the comparator.  Namely, the slave station 1b is set to the standard transmission level, the slave station 1a to the transmission level obtained by raising the difference of the reception level and the slave station 1c to the transmission level lowered by the difference of the reception level.

Title: Liquid crystal display device
Inventor: YAMAUCHI TAKAO
IPC: G02F1/137
Filed: 1993-12-20
Abstract: PURPOSE:To improve the utilization factor of light in a color display and to improve the display quality by providing a reflecting liquid crystal layer comprising a polymer liquid crystal and a liquid crystal layer having double refraction property in which a dye is mixed and laminated on the polymer liquid crystal layer. CONSTITUTION:A dichroic dye is mixed in a liquid crystal layer 7. A light subjected to circular polarization in a reflecting liquid crystal layer 2, for example, a light with a phase advanced by pi/2 in the clockwise direction is changed into a linearly polarized light with a phase advanced by pi in a phase layer 3, and changed into light with a phase advanced by 2pi in the liquid crystal layer 7. Since the molecular axis of the dichroic dye is arranged parallel to the substrate, the component of polarized light parallel to the major axis of the dye molecule is absorbed to give black color to the layer. On the other hand, when an electric field is applied on the liquid crystal layer 7, the liquid crystal molecule in a helical structure is oriented almost perpendicularly to the substrate so that the layer does not act as a halfwave plate. Thereby, the light with a phase advanced by pi from the phase layer 3 transmits through the liquid crystal molecule layer as it is. In this state, the component of polarized light is not parallel to the major axis of the dichroic dye which is not parallel to the substrate, so that light transmits through the layer. Thus, a light of specified color selected in the reflecting liquid crystal layer 2 is observed.
