IPC: H03M1/04
Filed: 1987-09-25
Abstract: PURPOSE:To obtain a primary prediction primary noise shaping A/D converter being effective even in case of a small signal by providing a means for generating a white noise of one bit, and a means for obtaining an output of a difference at two continuous sampling time points of its output. CONSTITUTION:As for a signal inputted from a terminal 1, an output 3 of a predicting device B and a signal of a terminal 4 are brought to D/A conversion and subtracted by a means 5 for taking a difference and accumulated by an integrator 7. Also, in this case, a digital signal of the terminal becomes an output signal of an A/D converter. The result of accumulation by the integrator 7 is added to a signal generated by a noise generating part C, by an adder 6 and whether it is positive or negative is decided by a comparator 8. The result of decision is held for one sampling period by an FF 11, and its inversion signal is applied to the predicting device B. In said generating part C, an output 12 of a difference at two continuous sampling time points of an output of a white noise generating means 15 for generating a white noise of one bit is obtained and superposed to an input of the comparator 8. Therefore, even when an input signal is small, the satisfactory S/N characteristic is obtained.

Title: Rechargeable battery device
Inventor: YAMASHITA MASATAKA
IPC: H02J7/04
Filed: 1990-09-14
Abstract: PURPOSE:To protect an internal secondary battery from overcharge by controlling the on-off of the charge current from an external charger with the on-off of a switch means inserted in series in the charge/discharge circuit of the secondary battery, even at misuse such as that it is charged with a charger other than an exclusive charger. CONSTITUTION:First, a switch means 5 is turned on to perform the charge based on the control of an external charger 6. After the voltage between the terminals of a secondary battery 2 has reached the specified first off voltage, the switch means 5 is turned on and turned off repeatedly to do pulse charge. When the voltage between the terminals of the secondary battery 2 during off of the pulse charge tops the specified second off voltage, it finishes the pulse charge. Hereby, even if an exclusive charger is not used, normal charge is performed, and the secondary battery can be prevented from being overcharged to the dangerous state, and it is safe and besides it can be used in quite the same way as an ordinary secondary battery.

Abstract: PURPOSE:To enable a wiring path passing above a wiring pass-enable block to be set efficiently and easily and reduce chip size by generating a rectangular shape with two terminals to be connected mutually being two opposing tops and by avoiding it every time the wiring passing prohibition block is passed. CONSTITUTION:When scanning is initiated from a starting point terminal A along a side (a) wiring prohibition block 20 is first reached. Then, a folded bent point is inserted, the side a is divided into segments a1, a2, and a3, and the segment a3 is moved to the outside of the block 20. In this case, it may be moved either above or below the block 20 but it is selected to move below the block owing to shorter path length. lt is repeated for both clockwise and counterclockwise sides until an end point B is reached. a path A-a1-a3-a4-a5-b-B is shorter than a path A-c-d1-d2-d3-d4-B. Therefore, the former is selected as a wiring path.

Abstract: PURPOSE:To efficiently produce fine powder of high-purity MgO having a fine and uniform particle diameter, by separately jetting Mg vapor and an inert gas into a reaction chamber, mixing both and bringing the mixed gas into contact with an oxygen-containing gas. CONSTITUTION:Mg vapor produced in a retort is introduced from an inlet pot 1 and jetted from a nozzle 3 into a reaction chamber 5.

Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To allow a user to know prior to printing whether or not an out-of-ink condition occurs during printing by a printer in a printing system. SOLUTION: When an instruction for executing printing is provided by a user, an RIP(raster image processor) turns off a printing start flag so that the printing is interrupted. The RIP requests transmission of a residual quantity of ink in a printer (S200) and receives the residual quantity of ink transmitted from the printer in response to the request (S210). The RIP predicts a quantity of ink necessary for the printing in the printer based on preview data. A residual quantity of the ink and the predicted necessary quantity are compared with each other by each color of the ink to be indicated by using a graph (S260 and S250). When the ink is deficient (S260: YES), the result is indicated (S270).
