Title: Smoothing differential arithmetic device
Inventor: NIIJIMA HIRONOBU
IPC: G06F17/18
Filed: 1986-01-13
Abstract: PURPOSE:To increase the smoothing differential arithmetic processing speed by using an exclusive arithmetic unit consisting of an adder, a weighting means, a multiplexer and a register to perform said arithmetic operation. CONSTITUTION:A normalizing means U12 multiplies the data stored in a register U7 by a normalizing constant K. For instance, it is possible to use a table consisting of a multiplier or a memory which delivers the signal obtained by multiplying the input signal by the constant K. Then a control circuit U14 applies the multiplier data N to a weighting means U3 and also the constant K to the means U12 respectively. Furthermore the control signal is applied to a delay means U13 to decide a delay amount in response to the smoothing point number N. In other words, the means U13 can be formed with registers M1-Mn cased with each other, the gates G1-Gn which extract the output signals of each register, and an OR gate. Thus the delay amount can be decided for the data extracted from the gate OR by opening one of those gates G1-Gn.

Title: Device for displaying character and graphic
Inventor: KUMAGAI YASUHIRO
IPC: G09F9/30
Filed: 1987-01-16
Abstract: PURPOSE:To display matters that demand special attention related to lighting/ extinction of a light source for transmission illumination on a liquid crystal display panel even at the time of extinguishing this light source by using a semitransparent display panel as the display panel. CONSTITUTION:This device consists of a semitransparent liquid crystal display panel 1, a cold cathode discharge tube 2 as the light source for transmission illumination on the rear face of the panel 1, a light source driving circuit 3 using a high frequency inverter, and a control circuit 4 which instructs lighting/ extinction. That is, a display device is incorporated in the device, and the light source 2 for transmission illumination is not lit in an initial state where the power source of the incorporating device is turned on. Since the liquid crystal display panel 1 is semitransparent in this case, the display quality is slightly degraded but the display can be read. At this time, the control circuit 4 waits for the use start request of the display device. When a preliminarily determined key switch on the operation board of the incorporating device is depressed, the control circuit 4 detects the use start request and sends a lighting instruction signal 5 to instruct the light source driving circuit 3 to light the light source.
