Title: Pressure sensitive input device
Inventor: ISHII TETSUYA
IPC: G06F3/048
Filed: 1990-07-27
Abstract: PURPOSE:To protect the glass plate on the pressure sensitive surface of the device when the device is transported by providing an auxiliary power source and alarming means and generating an alarm in the case the pressure sensitive surface is pressed while the main power supply is disconnected. CONSTITUTION:A supllied power source Vcc, battery BAT, and resistors Rx and Ry respectively constituting pressure sensitive input devices are provided and the voltage dividing ratio varies depending upon the pressed location along the (x) or (y) axis. Transistors QBU1 and QBU2 are turned on when the supplied power source Vcc is disconnected and a piezo-electric buzzer Buzz is controlled by means of the transistor QBU2 which is turned on when the power source Vcc is disconnected, receives power supply from the battery BAT, and produces sounds when one of the input devices is pressed. Therefore, the power supply to a position detecting means can be secured and the pressing of a pressure sensitive surface can be detected even after the main power supply Vcc is disconnected. In addition, since the alarming means Buzz is driven by means of the auxiliary power source BAT, an alarm can be issued when the pressure sensitive surface is wrongly pressed with no object of inputting information.

Title: Driving method for liquid crystal matrix display panel
Inventor: WAKITA HISAHIDE
IPC: G02F1/133
Filed: 1985-09-06
Abstract: PURPOSE:To make a display of high quality by applying a pulse voltage to on-off picture elements of a display panel according to the selection period and nonselection period of scanning electrodes and varying the width of pulses applied in the nonselection period. CONSTITUTION:When the display panel which has ferroelectric liquid crystal charged between substrates is driven, inverted pulses are applied to on picture elements in the latter half of a stage in the selection period of the scanning electrodes and to off picture elements in the former half to obtain a light transmission state; and uninverted pulses having the opposite polarity are applied in the other half stages and pulses having complete AC waveform are applied in the nonselection period to obtain high memory property. Thus, the width of pulses applied in the selection period is varied to perform on-off control over the picture elements and only an effective value is increased by decreasing the pulse width in the nonselection period and increasing the amplitude without inverting molecules to improve the memory property of the panel.

Title: D/a converter
Inventor: MATSUMOTO MASAAKI
IPC: H03M1/74
Filed: 1991-08-07
Abstract: PURPOSE:To prevent malfunction from occurring when fast input is performed by latching an input signal with an input latch circuit, and starting a decoding operation after receiving a perfect input signal in a D/A converter of cell array matrix system. CONSTITUTION:A four-bit D/A converter is comprised by forming a current switch cell array by using a CMOS two-input current switch cell. Four-bit digital input signals A0-A3 are separated into two pairs of A0, A1 and A2, A3, and they are applied to decoder circuits 12. 14. In such a case, A0 shows the most significant bit, and A3 shows the least significant bit. The decoder circuit 12 decodes the input A0, A1, and forms X address signals, and supplies them to a latch 13. Also, the decoder 14 decodes the input A2, A3, and forms Y address signals, and supplies them to a latch 15. An analog current generating part supplies an analog current by controlling the current switch cell 11 corresponding to the address signals from the latches 13, 15. Thereby, since the decoding operation is started after receiving the perfect input signal, the malfunction can be prevented from occurring.

Title: Pressure detecting device
Inventor: NAGAI TAKESHI
IPC: G01L1/10
Filed: 1998-07-14
Abstract: PROBLEM TO BE SOLVED: To detect pressure levels in a simple constitution by oscillating one end of plane- shaped pizoelectrics by an oscillation generating means, detecting the oscillation characteristics of the piezoelectrics which change in response to pressure when the piezoelectrics are applied with pressure by an oscillation detecting means, and computing the pressure on the basis of an output signal by a pressure computing means. SOLUTION: In an oscillation generating means 12, the part of the plane-shaped piezoelectrics 11a sandwiched by electrodes 12a and 12b is oscillated in response to an oscillation signal generated at a signal generating part 14. This oscillation is propagated to an oscillation detecting means 13 and an oscillation characteristics control means 16 via the part of the high-molecular piezoelectrics 11b to oscillate the overall plane-shaped piezoelectrics 11 with certain characteristics. A detection voltage is generated at the detecting means 13 in response to the oscillation. The oscillation of the overall piezoelectrics 11 also largely depends on the frequency of an oscillation signal. The frequency at which the detection voltage detected at the detecting means 13 first shows a local maximum is defined as the first resonance frequency.  When the piezoelectrics 11 are applied with pressure or weight, the first resonance frequency is approximately determined dependently on the length L of the piezoelectrics 11 and the velocity of sound, and the distortion and stress of the piezoelectrics 11 become maximum at its center.
