IPC: G03G13/09
Filed: 1983-04-27
Abstract: PURPOSE:To obtain a vivid and bright image by satisfying specific conditions in the relation between the quantity of a magnetic material in a toner and the particle size of the magnetic material. CONSTITUTION:A latent image holding body holding a latent image on the surface and a toner carrier carrying an insulating toner are arranged a certain gap apart from each other in a developing part. The toner is applied to the toner carrier by a magnetic means, and this applied layer has the thickness controlled to a value smaller than the gap of the toner carrier and is carried to the developing part, and the image is developed while applying an alternating electric field to the toner carrier. In this case, the relation between wt% magnetic material quantity Y in the toner and a particle size Xmum is selected to satisfy Y<=60X<1.23> (0.01<=X<=5). As the result, a vivid and bright picture is obtained with an ultrafine magnetic material satisfying the relation.

Title: Method for depositing thin metallic film
Inventor: YAMAMOTO HIROSHI
IPC: C23C16/14
Filed: 1987-03-27
Abstract: PURPOSE:To form flat thin metallic films having excellent adhesion on a substrate surface by executing formation of the thin metallic films and removal of the by-product of reaction sticking to the substrate surface repeatedly >=2 times at the time of depositing the thin metallic films on the substrate surface by a CVD method. CONSTITUTION:A gaseous mixture composed of gaseous WF6 and gaseous H2 is supplied to the surface of the substrate having an SiO2 film 2 in part of the surface of an Si wafer 1 and the substrate is heated to 200-600 deg.C to reduce WF6 in the Si- exposed part by Si and to form a metallic W film 3. The by-product of reaction 4 such as WFX (X=1-5) lower than WF6 is formed and adhered near to the boundary face of the W film 3 and the Si wafer 1 and WOXFY, etc., are formed and adhered by reaction with SiO2 onto the surface of the SiO2 film 2. The supply of the reactive gas is then stopped and after the gas is evacuated to a vacuum state, the substrate is heated to 300-600 deg.C to evaporate the by-product of reaction 4 such as WFX and WOXFY. The above-mentioned two stages, i.e., formation of the W film and the evaporation and removal of the by-product of reaction 4 are repeated in succession. The extremely flat W film having the excellent adhesiveness is thereby formed without allowing the by-product of reaction to remain in the Si-exposed part.

IPC: B28D1/22
Filed: 1990-03-22
Abstract: PURPOSE:To obtain arbitrarily arched thin members, and improve productivity in the post-process by controlling a slicing apparatus for making the cut end of a workpiece into an arched arbitrary form, and then cutting the workpiece thereby. CONSTITUTION:During the period of cutting operation, the displacement degree of blades is detected by a sensor 20 and the detected value is inputted in blade displacement degree control means 24. The blade displacement degree means 24 serve to set the aimed speed of a tension disc 9 while comparing the detected value and the aimed blade displacement degree. Therefore, during the period of cutting operation, when the displacement degree of a blade 10 becomes shifted from the aimed blade displacement degree, this is detected by the sensor 20, and the speed of the tension disc 9 is controlled in order to make the degree of the blade 10 converge on the aimed blade displacement degree. Accordingly, at each cut-in position, the displacement of the blade 10 positively becomes in accord with the aimed blade displacement degree. In this manner, the work piece 15 is cut surely into the form of a cut end alpha to be aimed.

Abstract: PURPOSE:To obtain a good recording image by improving the emitting state of a recording liquid by providing a control means for variably controlling at least one of the level and supply time of the electric energy supplied to a piezoelectric element when a recording liquid chamber is enlarged corresponding to the temp. of the recording liquid measured by a temp. measuring means. CONSTITUTION:In the control for correcting the emitting temp. of ink executed by a CPU 20, when the CPU 20 receives recording data 4 from the outside, said recording data is recorded on a buffer memory. Next, the CPU 20 receives the temp. data of an ink liquid from the temp. sensor in a sensor group 25. Subsequently, the addresses corresponding to the density value at every pixel of an internal ROM and the temp. data are set by the CPU 20 and the energy data at the times of the expansion and contraction of a pressure chamber 30 are read from the internal ROM. Continuously, these applied-energy data are transmitted to a head driver 24 in synchronous relation to dot recording. When the head driver 24 receives these applied energy data, at least either one of the generation time and magnitude of negative voltage Vrev is variably set so as to be reduced as temp. becomes higher to be applied to a piezoelectric actuator 15. As a result, even when the viscosity of an ink liquid changes corresponding to temp, the meniscus of the ink liquid is controlled so as to become a position suitable for ink emission.
