IPC: C01B33/141
Filed: 1978-02-13
Abstract: PURPOSE: To very economically produce a stable aq. silica sol fluid by treating an aq. soln. of an alkali metal silicate with a H-type cation exchange resin at below a predetermined temp. and adding the resulting acidic silica sol of high concn. to an aq. soln. of an alkali metal silicate at above a specific constant temp.  
     CONSTITUTION: An aq. soln. of above 5% (as silica) of an alkali metal silicate such as sodium silicate is treated with a H-type cation exchange resin at below 20, esp. below 10°C to form a stable transparent acidic silica sol soln. of high concn. The pH of the soln. is pref. below 4. The soln. is then mixed with an aq. soln. of an alkali metal silicate constantly at above 60°C until the ratio of SiO 2 /M 2 O (M; an alkali metal) becomes above 20. Thus, a stable aq. ailica sol fluid is obtd. contg. silica particles of about 10 mμ in diameter. The pH of the above mixed soln. is usually 8W10.

Abstract: PURPOSE:To obtain accurate post-equalization data of a symbol period even at a large linear distortion or at a low S/N without any complicated interpolation processing after equalizing processing in the automatic equalizer eliminating simultaneously line distortion of a data signal and a waveform signal. CONSTITUTION:A microprocessor 11 executes convolution calculation to a 1st reference data signal and a 2nd reference data signal at a receiver side and detects a phase location between a peak position of an impulse signal and a symbol period being the result of the calculation.

Abstract: PURPOSE:To attain an access with a single seeking action by using a memory to store the address information corresponding to a defective track to the information corresponding to a substrate track and storing the information on a nondefective track with no conversion and with free resetting. CONSTITUTION:Magnetic disks D0-Dn are positioned at each target track by means of a head selecting circuit 20 and a seeking action control circuit 10. The input head address and cylinder address information Y and X are supplied to a memory 100 from registers 70 and 60 via a selection switching circuit 80. The memory 100 stores the information Y and X corresponding to each substitute track set previously instead of those information Y and X corresponding to the defective track. The information Y and X corresponding to a nondefective track are stored with no conversion. Furthermore a resetting part 90 is connected to the memory 100 via the circuit 80. The memory 100 is rewritten with an address signal AD delivered from the part 90. Thus just a single seeking action is enough with an access action.

Title: Image forming device
Inventor: AOKI YOSHIO
IPC: G05D23/00
Filed: 1990-01-29
Abstract: PURPOSE:To prevent a fixing heater from excessive rise of the temp. and to reduce power consumption by controlling electric power in waiting and fixing so as to be lower than that at the time a driving power source is turned on and supplying the power the same as when the power source is turned on when the temp. is lowered during the fixing. CONSTITUTION:When the power source is turned on, a CPU 5 sends a signal to an AC phase control circuit 16, which energizes the heater 4 by a full wave AC, and the temp. of a fixing roller rises to a first set temp. When a thermister 13 detects that reaching the set temp. reaches the set temp., the energization to the heater 4 is switched to a half wave AC and the set temp. is maintained. When a printing signal is inputted during the waiting, the circuit 16 switches the energization to the heater 4 to the full wave AC again and the temp. of the fixing roller is raised to the set temp. When the rise of the temp. is detected, the energization is switched to the half wave AC again, which switching is repeated and the temp. required for the fixing is maintained. Thus, without excessive temp. rising during the waiting and fixing, the power consumption of the heater can be reduced.
