Title: Developing device
Inventor: ENOKI SHIGEKAZU
IPC: G03G15/00
Filed: 1991-04-13
Abstract: PURPOSE:To make image quality higher by improving the density of an image while gradation is maintained, preventing the growing of the fine part of the image, and simultaneously, using a developer having an actual sphere and an uniform small grain diameter. CONSTITUTION:A developing roller 5 has a substrate composed of a conductive roller 10, a medium resistor 12 which is fixed on the surface of the circumference of the substrate and has the resistance of 10<3>--10<8>OMEGAcm and a high resistor 11 having the resistance higher than that of the medium resistor 12. Both resistors 11 and 12 are friction-charged to a negative polarity by a toner supplying roller 6. The high resistor 11 has more charge quantities, by a difference in the resistivity of both resistors 11 and 12, and their surface potentials have the difference, to form a closed electric field between both. Toner is strongly restrained by the closed electric field, held on the developing roller 5, and carried to a developing region, to visualize an electrostatic latent image. For this toner, a thing having the actual sphere and uniform small grain diameter is used.

IPC: C09D11/18
Filed: 1995-05-02
Abstract: PURPOSE: To assure the quality of an ink follow-up member and the quality of a pen itself and to eliminate the temperature rise or oil-extraction due to a long-term preservation to be stabilized by adding silane surface modifying agent to the gelatinizer of a gel-like ink follow-up member using fine particle silica. CONSTITUTION: Ink follow-up composition for a water base ink ballpoint pen contains at least one type of solvent selected from a group consisting of hard volatile organic solvent and nonvolatile organic solvent, fine particle silica as gelatinizing material and silane surface modifying agent. The organic solvent has 0.4wt.% or less of evaporation loss under the conditions of 90 deg.C and 5 hours. Ink used for a water base ink ballpoint pen contains colorant, solvent and water, and has 1 to 2000mPa/sec of ink viscosity at 25 deg.C. Thus, it can be used for a water base ink ballpoint pen containing 0.1% or more of surfactant, 30% or more of alcohol solvent or aqueous emulsion, and the ink follow-up composition and the pen stable for a long-term preservation are obtained.

Title: Water-repellent coated article
Inventor: KASHIWABARA HIDEKI
IPC: B32B15/082
Filed: 1994-04-25
Abstract: PURPOSE:To obtain a water-repellent coated article having coating properties capable of imparting excellent non-stickiness, abrasion resistance and corrosion resistance by providing a coating layer of a compd. having a fluorine atom on the polysilazane-containing coating layer provided on the surface of a base material to strongly bond the same to the surface of the base material composed of metal or glass. CONSTITUTION:A soln. of polysilazane alone or a polysilazane compsn. is applied to the surface of a base material composed of metal or glass and the coated base material is dried at about 100 deg.C to form a film. When the coated base material is dried at relatively low temp. as mentioned above, the reaction activity of polysilazane can remain and, when a coating layer of a fluorine-containing compd. having a functional group is provided on the polysilazane-containing coating layer in such a state that the reaction activity of polysilazane remains, polysilazane is reacted with the functional group of the fluorine-containing compd. of a topcoat layer at the time of baking and, therefore, the topcoat layer is strongly bonded to the base material and the polysilazane layer being an undercoat layer covers the surface of the base material densely and, as a result, good corrosion resistance, damage resistance and abrasion resistance can be imparted to the base material. Since the topcoat layer has a fluorine atom, non-stickiness and water repellency can be imparted to the surface of the base material.

Filed: 1986-05-13
Abstract: PURPOSE:To reduce toner consumption by driving a shutter device for interrupting the scanning light of an exposure means so that only an area to be transferred to a recording body on a photosensitive body is exposed. CONSTITUTION:A shutter device 22a arranged over a scanning light incident slit 18a is driven by a solenoid 22c and a rink 22b.

Title: Spindle motor driving circuit of magnetic disk device
Inventor: HATSUTORI MASAKATSU
IPC: G11B19/20
Filed: 1984-05-31
Abstract: PURPOSE:To completely prevent the destructive accident of a magnetic head due to the magnetic attraction between the magnetic head and a magnetic disk, by detecting the magnetic attraction between the magnetic disk and magnetic head and controlling and stopping the actuation of a spindle motor when the magnetic attraction occurs between the magnetic disk and magnetic head. CONSTITUTION:In case magnetic attraction occurs between a magnetic disk 11 and magnetic head 12, the starting torque of a spindle motor 1 becomes larger than normal one, since the magnetic attraction between the magnetic disk 11 and magnetic head 12 is added to statical frictional force. When the magnetic attraction occurs, the spindle motor 1 cannot be started, because the electric current supplied to the driving winding 2 of the spindle motor 1 from an electric current limiting circuit 8 at the time of starting is set to the normally required minimum. Therefore, a main control circuit 10 cannot get a start signal 100 from a rotation detecting circuit 7 and starts to monitor the set time of a timer 9. When the start signal 100 cannot be obtained even when a preset maximum time has passed, the main control circuit 10 stops the output of a start signal 200 outputted to an output driver 5.

Title: Method and device for instantaneous compression and expansion of audio signal
Inventor: TSUKAMOTO KENKICHI
IPC: G11B20/04
Filed: 1982-06-24
Abstract: PURPOSE:To obtain a playback sound with extremely high quality in an auditorily large dynamic range, by obtaining an instantaneously compressed signal which contains only frequency componensts that are contained in an original signal and has a relatively enphasized fine structure which is auditorily important to the original auido signal. CONSTITUTION:An original signal A(t) is modulated by an auxiliary signal g(t) and a bypath filter 13 assumes the maximum frequency of an original audio signal A(t) as Max{A(t)} to use a frequency not containing <=2 times of its frequency as f{A(t)}. Then, exactly the same frequency component as A(t) is retained purely in 0- Max{A(t)} with regard to the frequency spectrum of its output i(t), but a(t) is not obtained. For this purpose, a modulator 18 performs demodulation by g(t) wherein a positive or negative rectangular wave synchronizing with, for example, g(t) and ''2'' alternate to obtain the output i(t). This output is passed through a low-pass filter 19 to obtain the instantaneously compressed or expanded signal a(t) of the original signal A(t). The a(t) contains only the frequency components contained in the original signal A(t).
