Title: Piezoelectric oscillation circuit
Inventor: SATO TADASHI
IPC: H03B5/32
Filed: 1994-09-30
Abstract: PURPOSE: To shorten starting time and to improve repeating accuracy by divid ing a capacitor on the output side of an inverter into two parts, connecting one end of the capacitor to the output terminal of the inverter and connecting the other end to Vdd and GND. CONSTITUTION: A crystal oscillator and feedback resistor Rf are connected in parallel between the input and output of the inverter 2 and a capacitor CG on the input side of the inverter 2 and a capacitor CD on the output side of the inverter 2 are connected to both the ends of the oscillator. One side of the capacitor CG is connected to Vdd, the capacitor CD is divided into CD1 and CD2, one side of the CD1 is connected to Vdd, and one side of the CD2 is connected to GND. When the capacity of the CD2 is gradually increased, from OPF, oscillation starting time also is gradually shortened and current consumption is gradually reduced. When the CD1 is 15pF if CD1=CD2, the shortest oscillation time is obtained and the current consumption is also minimized when the CD2 is 15pF.

Abstract: PURPOSE:To reproduce a stereoscopic picture having no flicker by setting the one field period of a video signal for the stereoscopic picture and the switching speed of a shutter spectacles to 1/2 of the original period and speed by reading twice and at a speed twice as fast as at the time of writing. CONSTITUTION:The signal for the stereoscopic picture in which left eye information and right eye information are switch for every one field (60 Hz) is converted to a digital signal and inputted to field memories 6-9. The contents of the signal written in the memories 6-9 are read at the speed twice as fast as the writing speed. Accordingly, if the respective output signals (f-i) of the read memories 6-9 are switched by a signal switching device 10 for every period of 1/2 of the one field period of an input signal, the output has the same right eye information and the left eye information alternately outputted twice for two field period. The shutter spectacle 13 for the left eye and the shutter spectacle 14 for the right eye are alternately switched in the cycle of 60 Hz by a shutter spectacles control signal generating circuit 5. Thereby, the stereoscopic picture having no flicker can be reproduced.

Title: Arithmetic processing method
Inventor: MIYAMOTO TAKAHIRO
IPC: G06F7/552
Filed: 1990-10-01
Abstract: PURPOSE:To obtain an approximate value at a high speed just with a single operation of a multiplication by providing a multiplier means which obtains an arithmetic result consisting of two words and a means which takes a higher rank word out of the multiplication result of two words as an approximate value. CONSTITUTION:When an approximate value is particularly obtained at a high speed by multiplying a positive integer by a constant larger than 0 and smaller than 1 in the calculation of approximate values, a CPU containing an integer multiplication functions notices a fact that a higher rank word 204 of the 2-word number 203 is equal to the value obtained by multiplying a lower rank word 205 by the (maximum value + 1) of a word and then applies the value where the constant to be multiplied is previously converted into one word. Therefore no division is needed in the calculation where an approximate value multiplied by a constant larger than 0 and smaller than 1 is obtained. Thus the computing speed can be approximately doubled. In such a way, an approximate value is obtained with a single operation of a multiplication without performing any division.

The vessel 4 is heated by a heater 8 and the ozone is fed into the vessel 4. The ozone is generated by the oxygen supplied from a cylinder 9 into an ozone generator 10. The ozone is passed through a flow passage selector cock 11 and is diffused by a ball diffuser 12 into the acidic sample water 1. The ozone is brought into gas-liquid contact with the sample water 1 in the vessel 4 to oxide and decompose the phosphorus compd. contained in said water to PO<-3>4. The excess ozone arrives at a waste ozone decomposing device 14 where the ozone is decomposed to harmless oxygen. The oxygen is then released into the atm. air. The ozone blown into the vessel 4 for the specified time is passed through a bypass pipe 15 and is conducted to the device 14 by operating cocks 11, 13 so as to be decomposed and released.
