Title: Silica gel and its production, and production of synthetic silica glass powder
Inventor: ENDO HOZUMI
IPC: C01B33/152
Filed: 1995-02-03
Abstract: PURPOSE: To obtain silica gel with abnormal particles detected as black spots at or fewer than a specific number by sol-gel process while heating at specified conditions under a flow of N2 gas, and to obtain synthetic silica glass powder with improved quality by baking the silica gel. CONSTITUTION: A reaction unit having its inner wall bearing a scale layer with a thickness not greater than debonding limit is charged with a silicon compound such as an alkoxysilane and about 10 equivalent times of water to conduct a hydrolyzing condensation reaction under agitation to obtain silica gel <=1000μm in particle diameter. The silica gel is then ground and heated to >=100 deg.C to remove the water and the alcohol, etc., formed during the hydrolysis, thus dry gel <=30wt.% in moisture content is obtained. Next, the dry gel is classified to bring its particle size distribution into about 100-200μm and then heated in an N2 gas atmosphere at 800 deg.C for 15min, thus obtaining the objective silica gel <=200 counts/10g in the number of abnormal particles detected as black spots.  The dry gel after classification is baked by raising temperature from room temperature to about 1200 deg.C to obtain the objective synthetic silica glass powder each <=1ppm in Fe and Cr contents and each <=100ppb in Na and K contents.

Title: Binary counter
Inventor: AKAZAWA YUKIO
IPC: H03K23/00
Filed: 1980-02-15
Abstract: PURPOSE:To realize not only a high speed but a low power consumption with a  simple constitution of circuit, by adding a D-FF and then applying the output of the D-FF to the reset input of the FF that forms a counter. CONSTITUTION:When the input pulse is applied through the terminal 1, FF1-FFn are turned on and off repetitively. Then NAND gate 3 is set at a low level when FF2-FFn are all set at a high level. In this case, if a fall is caused to the input signal, the D-FF reads the NAND output to turn to a low level. Thus the R signal is supplied to all FFs to start a resetting action. Then FF2-FFn are preset at the values designated by P2-Pn. And either one of P2-Pn is at a low level and read into the FF, and thus the output of the gate 3 is turned to a high level. When a fall occurs to the next input signal, the output of the gate 3 is read into the D-FF. Thus the D-FF turns to a high level to cancel the resetting action form. As a result, a delay equivalent to two units of FF has just to be given within an input period for the maximum operation speed. Thus a high speed and low power consumption can be realized.

Filed: 1989-01-27
Abstract: PURPOSE:To prevent toner from press-bonding to a transfer intermediate body and to prevent the occurrence of an image noise and the reduction of a life by adding a material for making a wettability small to the transfer intermediate body. CONSTITUTION:The material for making the wettability small is added to the transfer intermediate body 2 which is arranged in a contact state to the photosensitive body 1.
