Abstract: PURPOSE:To prevent the access of a system to an unaccessible address space by storing previously the accessible upper and lower limit levels in a register. CONSTITUTION:The maximum limit addresses MAXADO-19 and the minimum limit addresses MINADO-19 are previously stored in a register 13 from a system. If the access addresses outputted to the address buses AO-A19 from the system get out of an accessible address space, any one of a comparison computing element 14 or 15 outputs a signal to an OR circuit 16 and activates an OVER signal. Under such conditions, a CE signal is set at a low level and a WE signal is also set at a low level so that the system writes the data. Meanwhile the output of a logical circuit 19 becomes to be at a high level making a register 22 to be set. Then an INT signal is outputted.

Title: Level converting circuit
Inventor: OGAWA SHUJI
IPC: H03K19/0175
Filed: 1992-11-17
Abstract: PURPOSE:To enable accurate level conversion not affected by variation in source voltage by providing a bipolar transistor(TR) which has a base-emitter voltage as high as the difference voltage between a reference voltage and a voltage proportional to the emitter current and making a current, which is a specific multiple of the collector current flowing through this TR, constant through a current mirror circuit. CONSTITUTION:First and second bipolar TRs 22 and 23 are connected through a diode to generate the constant reference voltage V3. Then the collector current Ic of a 3rd bipolar TR 25 is made constant by utilizing the reference voltage Va. Further, the collector current Ic is multiplied by (n) through the current mirror circuit 30 and supplied to current distributing devices TP1 and TP2. Namely, the bipolar TRs are used for a constant current source. Therefore, variation in source voltage becomes less than that of an MOS-FET, so the current flowing through the current mirror circuit can stably be made constant and the accurate level converting operation is obtained.

Title: Hand-free starting/stopping method and device for speech recognition system
Inventor: WHITE DANIEL FREDERICK
IPC: G10L15/00
Filed: 1999-10-29
Abstract: PROBLEM TO BE SOLVED: To turn on/off a speech recognition system without using hand by transmitting a starting or stopping command to the speech recognition system, when an voice signal from a microphone matches to one of sets of reference voice signals. SOLUTION: A filter 221 is designed in a through hand region where only frequency showing a non-language start/stop signal is traveled. The start/stop signal is traveled through a start/stop logic 222, and is transmitted to a voice recognition system software so as to start or stop voice input acceptance from an operator headset 210. A process monitors and analyses a system input signal, and confirms whether the input signal matches to a reference for turning on a switch of the speech recognition system. When the input signal matches to the reference for turning on the switch of the speech recognition system, the switch of the speech recognition system is turned on. When the input signal matches to the reference for turning off the switch of the speech recognition system, the switch of the speech recognition system is turned off.

Abstract: PURPOSE:To improve the probability to receive/record the image data even if residual amount of the recording paper be comes little by recording the image data on both sides of the recording paper based on the image information stored in a storage in a both-side recording mode selection state. CONSTITUTION:The received image data are continuously accumulated in a storage means until the data reach a quantity equivalent to one page. When a both-side recording mode is selected by a both-side recording and selecting means, a single-side recording mode is set if an odd numbered page is presently processed. Then the image data are recorded on the surface of the transfer paper supplied from a paper feeding cassette 35. The recorded transfer paper is inverted and transferred through a refeeding paper loop 36 and kept waiting at the position of a resist roller 37. Then an even numbered page is processed and the image data are recorded on the rear side of the recorded transfer paper. Then the transfer paper recorded on its both sides is ejected to each pin 55 of a sorter unit 3. Therefore the necessary number of transfer paper can be halved when a small amount of transfer paper remains at a copying machine. Then the receiving/recording probability of the image data can be improved.
