Title: Water-repellent silica sol and its production
Inventor: UMIGAMI AKIRA
IPC: C09D7/62
Filed: 1990-08-27
Abstract: PURPOSE:To obtain a water-repellent silica sol which can be dispersed in a nonpolar org. solvent and shows excellent dispersion stability by making the surface of colloidal silica particles water-repellent with alkyl-substd. silane and specifying the particle size of the water-repellent colloid particles. CONSTITUTION:The surface of colloidal silica particles is made water-repellent with alkyl-substd. silane by effecting the reaction of silica colloid dispersed in a nonpolar org. solvent with alkyl-substd. silane. Thus, water-repellent silica sol containing colloidal silica particles with water-repellent surface and <=100nm particle diameter can be obtained. The silica colloid dispersed in a nonpolar org. solvent is prepared, for example, by adding a pH controller to a water- dispersed silica colloid to obtain pH1-5, adding a nonpolar org. solvent and a surfactant to make an emulsion, and then effecting azeotropic dehydration.

Filed: 1985-10-08
Abstract: PURPOSE:To remove the necessity of adjusting a comparator while referring to a manual by making the reference level of the comparator have an optimum value for every sensor to be compared in a paper size discriminating mode. CONSTITUTION:In an adjusting mode, a reference voltage is gradually raised and the voltage i/2x times the reference voltage at the time when the output of a comparator 9 reaches a level 'H' is outputted from Port B to discriminate the state of Sin. The value v/2x is that of the reference voltage at the time when the output of the sensor 2in is actually detected by the comparator. For the reference voltage thus established, it is checked that the output of the comparator 9 reaches a level 'L' and the value corresponding to the reference voltage at this time is stored in the i'th memory Mi. The level of the reference voltage to be applied to the comparator when a paper size is detected is stored in a memory for every sensor. Based on the detecting levels of the sensors thus stored in the memories in a sub CPU 6, the reference level to be outputted to the comparator is set and the size of a document is detected.

IPC: H03K5/26
Filed: 1988-09-08
Abstract: PURPOSE:To reduce the residual error component of a phase error signal by deriving output of second level in the pulse period of an input signal from the front edge to the rear edge of a reference signal, the output of first level in a first period from the rear edge of the reference signal, and the output of second level in a period other than the first period as the error signal. CONSTITUTION:The detecting signal of a detection circuit 110 is supplied to the control terminal of an output circuit 120, and also, to a latch circuit 130. The latch circuit 130 latches the detecting signal at the trailing edge of the rear edge of the reference signal, and the output of the latch circuit is supplied to the output circuit 120 and a delay circuit 140. When the latch circuit 130 latches no detecting signal, the output of second level (-E) can be obtained. Thereby, the waveform of the error signal can be obtained as (T) in the period of the level -E, and as (2T) in the period of level +E, and (T) in the period of the level -E, sequentially. Therefore, since the component remaining as the residual error component can be cancel led by (+) and (-), an accurate phase error component can be obtained.

Abstract: PURPOSE:To accurately set a recording medium at a prescribed position on a holding surface for the recording medium, by using a slant feed roller, a guide plate and a sheet stop means to position the recording medium on the holding surface of a recording medium holding means. CONSTITUTION:A slant feed roller 23 is set within an opening 22 and under the holding surface of a recording medium holding means.

Filed: 1988-09-09
Abstract: PURPOSE:To conduct the normal IC test by correcting a pulse waveform into a pulse waveform having a tendency to have an overshoot even if an unsharpened part takes place to the shoulder of the leading of the pulse. CONSTITUTION:Two conductors 3A, 3B of a coupling line 3 are formed in parallel onto an insulation board and the two conductors 3A, 3B are made of microstrip lines with respect to a pulse transmission line 1 and the same characteristic impedance as that of the pulse transmission line 1 is attained for the matching.
