Title: Compound waterproof sheet, waterproofing method therefor, and holding shaft body therefor
Inventor: AOYANAGI JUN
IPC: E04D5/14
Filed: 1993-11-18
Abstract: PURPOSE:To make an improved asphalt sheet without a core material usable in an insulation method by a method wherein a highly elastic asphalt sheet is partly fixed, penetrating through holes scattered over a resin sheet, to a cloth by means of point adhesion. CONSTITUTION:Bitumen and SBS(styrene-butadiene-styrene) are kneaded and heat melted, and highly elastic asphalt sheets 1-l, 1-2 are prepared. Then, the highly elastic asphalt sheets 1-1, 1-2 are partly fixed, penetrating through holes 3-1, 3-2 scattered over # resin sheets 2-1, 2-2, to cloths 4-1 to 4-3, and integrated into one body. Therefore, in the case where excessive shearing stress is applied to a compound waterproof sheet, the sheet expands and contracts, with its parts fixed by point adhesion displaced, and a waterproof layer can be kept in a correct position while concentration of load to the fixing points is relieved. Furthermore, the sheets can be bonded together liquidtightly by making the cloths 4-1 to 4-3 and the asphalt sheets 1-1, 1-2 unbonded at their end parts.

Title: Pll frequency synthesizer
Inventor: OGAWA YOSHIYUKI
IPC: H03L7/18
Filed: 1985-12-20
Abstract: PURPOSE:To raise the response speed and reduce the phase noise by adding a voltage corresponding to a desired frequency to give it to a voltage controlled oscillator and giving required frequency division ratio data to a programmable counter. CONSTITUTION:An adding amplifier 7 adds the output of a low pass filter 2 and that of a DA converter 11 and amplifies the addition result, and the output is given to a voltage controlled oscillator 3. The first code converter 8 converts the output code of a latch 9 to such frequency division ratio code that a programmable counter 4 is a frequency divider corresponding to a set frequency. There is little difference between this operation and the operation that the set frequency is outputted to the voltage controlled oscillator 3 from the outside of a system through the DA converter 11 at a switching time. The output voltage of the low pass filter is not quickly changed and its time constant is made larger, and the phase jitter of the output frequency is reduced. The timing of setting (switching) of the output frequency is synchronized with that of phase comparison of the programmable counter 4 to minimize the disturbance.

Title: Method and device for electrophotography
Inventor: UMEDA MINORU
IPC: G03G21/00
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To maintain the good image quality of environment-resistance for a long time with no deterioration of a photoreceptor surface caused by ozone and ions by a corona discharge, even in the case of repeatedly using the photoreceptor in operation of a copying process, by detecting the humidity rise in a copying environment and bringing antioxidant into contact with, or supplying to the photoreceptor surface. SOLUTION: The humidity rise in the copying environment, or the lowering of the electrostatic charging potential of the photoreceptor 2 is detected, and the antioxidant is intermittently brought into contact with, or supplied to the surface of the photoreceptor 2 through a contact member 17 coming into contact with the photoreceptor 2. By detecting the humidity rise in the copying environment and the lowering of the electrostatic charging potential of the photoreceptor 2, supplying the proper antioxidant to the uppermost surface of the photoreceptor 2 and holding the antioxidant in such a way, the uppermost surface of the photoreceptor 2 is protected from being in an oxidant atmosphere caused by the corona discharge by using the antioxidant, and the formation, or adsorption of hydrophilic material on the surface of the photoreceptor 2 is prevented.  Thus, the stable image is obtained for a long time without causing the deterioration of the image quality.

Abstract: PURPOSE:To reduce the degree of magnetic coupling between each of reactors without impeding the ventilation of cooling air by a method wherein a shielding plate, having the circulative property and the action with which the passing magnetic flux is cancelled by an eddy current, is provided between each of a plurality of reactors. CONSTITUTION:A shielding plate 15 consists of the highly conductive non- magnetic metal material such as aluminum or copper and the like, a number of ventilation holes l5b are formed thereon, and the plate 15 is fixed by passing it through each mounting hole l5a using a bolt 9 in the state wherein the plate 15 is pinched between supporting frames 5B and 6A. A slit 150 is formed on the shielding plate 15 ranging from its center part toward the external circumferential end, and the oveheating of the shielding plate is prevented by extending the current circuit of an eddy current equivalently. As both reactors are coupled through the intermediary of a thin disc-like shielding plate 15, the distance (l) between each coil of the reactors A and B can be reduced sharply, and the miniaturization and lightweightedness of the reactor can be achieved. As a number of air-circulating holes l5b are formed on the circumference of the shielding plate 15, the stream of cooling air is not impeded.
