Title: Paper supplying device
Inventor: OKADA NAOFUMI
IPC: G03G15/00
Filed: 1989-05-12
Abstract: PURPOSE:To make a paper supplying device compact and prevent double feed by providing a duct with a fan for producing an air current from a suction part to a blow part, and an air valve to suck air selectively from the suction part or the outside. CONSTITUTION:A solenoid 71 is off when starting paper supply to generate an air current from a suction part 3 to a blow part 4 by a fan 6, so air is blown to the forward end part of document A at the blow part 4 to let the uppermost document float, and the manuscript is sucked by a suction belt 2 by suction at the suction part 3. In this suction condition, the suction belt 2 rotates in the direction of illustrated arrows to feed the uppermost manuscript right. At this timing when this manuscript is fed for a certain degree, the solenoid 71 gets on to rotate tan air valve 7 by 90deg. for shielding a duct on the side of the suction part 3 to stop suction by the suction part 3. Double feed of the manuscripts can thus be prevented. At this time, blow at the blow part 4 is performed continuously.

IPC: C08G8/00
Filed: 1984-06-12
Abstract: PURPOSE:To obtain the titled resin without metallic corrosion of a reaction kettle, by reacting a phenol with a formaldehyde in the presence of a hydrochloric acid catalyst, neutralizing the reaction mixture by NaOH and concentrating it by dehydration. CONSTITUTION:A phenol is reacted with a formaldehyde at a formaldehyde/phenol molar ratio of, preferably, 0.5-0.9 in the presence of a hydrochloric acid catalyst (e.g., hydrochloric acid alone or a combination thereof with oxalic acid). To this reaction mixture, NaOH (preferably, 1-20% aqueous NaOH solution) in an amount, preferably, 1.0-1.1 times that necessary for neutralizing the acidic substance is fed and reacted, and the reaction mixture is concentrated by dehydration to produce a solid novolak phenolic resin. According to this process, the neutralization prevents hydrogen chloride gas from escaping from the reaction system in the step of concentration by dehydration and improves the metallic corrosion of the reaction kettle.

Abstract: PROBLEM TO BE SOLVED: To keep a toilet seat sheet in a spread state and in the state of not being detached from a toilet seat easily by holding the toilet seat sheet so as to cover the toilet seat by pulling one end in the state of holding another end at the time of taking out the toilet seat sheet one by one. SOLUTION: At the time of using this toilet seat sheet 5, the other end part 52 of the sheet 5, which is seen from a taking-out part 43 and is nearest to this side, is picked by a single hand to pull out from a keeping part 42 and the part 52 is pulled to the end part of the toilet seat 2. Since a one end part 51 is inserted by a substrate part 41 and a pressing plate 44, the part 51 of the sheet 5 is still kept in a holder 4. Consequently, the sheet 5 comes into the state of covering the seat 2 and at the time of putting a hand away from the part 52 as it is, the sheet 5 is mounted in the state of spreading on the seat 2. At the time of sitting on the sheet 5, the sheet 5 is not detached from the seat 2 as it is kept by the part 51. In addition, the sheet can be pull-cut away from a machine stitch 53 by strongly pulling the part 52 after using.

Title: Inverter circuit
Inventor: YUZAWA NOBORU
IPC: H03K17/16
Filed: 1986-05-28
Abstract: PURPOSE:To use a constant current circuit by a low voltage driving, to decrease a through current and to operate a circuit in high frequency by using an NPN transistor as a switch, sharing the voltage by the NPN transistor and constituting the constant current circuit of a low voltage. CONSTITUTION:As a power source side switching element, a PNP transistor 6 is used. As the element inserted to the emitter side of an NPN transistor 2, a resistance 8 is used, and as the switching element connected in parallel to the resistance, an NMOS9 is used. In the circuit, at the time of changing-over timing from H to L of an input (in) signal, in2 is made into the condition of L at a time t1. Since an NPN transistor 7 comes to be off in the condition, the PNP transistor 6 is shifted to the off condition. At such a time, since the NPN transistor 2 is turned on and the NMOS9 is the off condition, the current of a constant limit or above will not flow at the emitter of the NPN transistor 2. Consequently, since the switching loss can be decreased, an operation can be executed in high frequency.

SOLUTION: Since hypochloric acid capable of being easily formed by electrolyzing a very small amt. of a saline soln. is decomposed by org. matter in air or soil to become water, it has no remaining properties. Then, a large-scaled concrete tank, a biodegradable plastic bag or a housing covered with a sheet is used as a container 1 and soil or sludge contaminated with an organomercury compd. (organomercury compd.-containing matter) charged in the container 1 from an injection port and, succeedingly, hypochloric acid containing water is charged in the container 1 and the injection port 7 is closed by a hermetically closable lid 2. The container is allowed to stand for several days - several months to decompose and eliminate the organomercury compd.
