Title: Cad device
Inventor: MORIMOTO KENJI
IPC: G06F17/50
Filed: 1992-07-17
Abstract: PURPOSE:To improve check efficiency and to shorten the time required for preparing a drawing by displaying and printing a checked part and an unchecked new input part while distinguishing them by colors and lightness or the like. CONSTITUTION:When graphic/graphic reading is selected by a keyboard 1, a graphic reading part 21 reads the graphic/drawing from a storage part 26, and an attribute reading part 22 reads an attribute added to the graphic/drawing from the storage part 26. A CRT 4 displays the graphic/drawing read by the graphic reading part 21 in the color corresponding to the attribute read by the attribute reading part 22. Further, when a manually inputted graphic is added to the graphic/drawing displayed on the CRT 4, an attribute adding part 24 adds an attribute showing the new input to the manually inputted part. Then, the CRT 4 displays the newly inputted part in the color different from that of the registered graphic/drawing or prepared drawing, which does not require any check, and displays them in colors corresponding to attributes.

Title: Power supply circuit
Inventor: TSUJIMURA KATSUTO
IPC: H02J1/00
Filed: 1991-07-31
Abstract: PURPOSE:To cope with fluctuation of load voltage without interrupting power supply to the load by providing an LED connected with the output terminal of a voltage supply, a diode connected between the output terminal and a joint, and a resistor connected between a voltage detecting terminal and the joint. CONSTITUTION:When the voltage of a power supply 1 is set lower than the voltage of a power-supply 2, power is fed from the power supply 1 through a diode d11 to a load 3. Since the voltage V3 across the load 3 is higher than the set voltage of the power supply 2, the power supply 2 functions to lower the output voltage and thereby the voltage V2 of the power supply 2 drops below a voltage V3 thus turning a diode d21 OFF. The power-supply 2 functions to lower the output voltage furthermore, but a diode d22 connected between the remote sensing terminal +s and the power supply terminal (o) of the power supply 2 is turned ON to clamp the voltage V2 of the power supply 2 and thereby the system enters into waiting state before the voltage V2 drops to 0V.

Title: Voice synthesizer
Inventor: KITAMURA TORU
IPC: G10L13/047
Filed: 1987-07-30
Abstract: PURPOSE: To hold the naturality of synthesized voice without increasing the capacity of a voice buffer memory regardless of a large number of characters in a one-exhalation paragraph by automatically providing an upper limit of the number of characters processed at a time to synthesize voice. CONSTITUTION: A character number counter 15 counts the number of characters to a voice data buffer memory 12, and when the number of characters of the one-exhalation paragraph reaches a prescribed value, a character number-over signal O is generated. When the signal O is sent to a voice synthesis part 13, voice data up to the position of a clause break mark existing last from the head is synthesized. Thus, the capacity of the memory 12 is reduced without putting restrictions on the number of characters of the one-exhalation paragraph of an input sentence, and an unnaturally long pause is not inserted to a breathing spell position even if the processing speed is low.
