Title: Production of solid urea resin
Inventor: HIRATA ATSUMI
IPC: C08G12/00
Filed: 1980-05-30
Abstract: PURPOSE: To obtain a solid urea resin having a sufficient ability as a plasticizer in high yields, by reacting urea with formaldehyde in the presence of an alkaline catalyst while controlling the water content of the reaction system at a specified level, and removing the water by vacuum.  
     CONSTITUTION: Urea is reacted with formaldehyde in the presence of an alkaline catalyst while the water content of the reaction system is controlled at 13W25wt% with respect to the reaction charge. Then, the reaction mixture is cooled, solidified and dried under vacuum, preferably, until the water content reaches 3wt% or below. When the water content of the reaction system is below 13wt%, the system can not be maintained in the liquid state, and the uniform reaction is not possible, and when the water content exceeds 25wt%, the system after completion of the reaction, when cooled, is separated into two phases, i.e., supernatent layer and precipitates. Accordingly, dewatering by a centrifuge or a filter press becomes necessary and the yield is also decreased.

Abstract: PURPOSE:To keep the temperature of each sample constant and move less a refrigerant supply part by attaching plural samples to a cooling part so that they are arranged at equal distances and holding them so that they are moved to a measuring position by rotation. CONSTITUTION:A holder 3 is attached rotatably through an attaching member so that lengths of heat conduction paths to individual samples 2 from a cooling part 4 are equal to one another. When samples are cooled with a refrigerant such as a liquid helium, a liquid nitrogen, or the like in the cooling part 4, they are cooled by heat conduction from the cooling part through the member 11 and the holder 3. Since individual samples 2 are at equal distances from the cooling part 4 thermally, they are cooled to the same temperature. When a motor is rotated in this state, the holder 3 is rotated, and samples are moved to the measuring position successively and are irradiated with a measuring light to perform measurement. Since the holder 3 is rotated, operations for sealing and measurement are facilitated.

Abstract: PROBLEM TO BE SOLVED: To prolong the lives of a magnetic brush electrifying device and a photoreceptive drum in an image forming device at which a developing device is compatible with a cleaning device. SOLUTION: An auxiliary electrifying device is arranged between a transfer device and an electrifying device, so that toner remaining after transfer on a photoreceptive drum surface is easily taken by the magnetic brush of the electrifying device by applying bias having a positive polarity to the auxiliary electrifying device at the image forming area(area 1) of the photoreceptive drum surface. The bias having a negative polarity is applied to the auxiliary electrifying device at the image nonforming area(area 2) of the photoreceptive drum surface. Thus, Vback potential is generated even though the magnetic brush is not brought into contact and is not actuated by separating from the photoreceptive drum surface, so that the toner remaining after transfer is recovered by the developing device.  The magnetic brush and the photoreceptive drum are not brought into contact at the image nonforming area, so that the livers of both members are prolonged.

Title: Room-inside shielding device
Inventor: MURAKAMI KEIICHI
IPC: E06B9/24
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To shield inside of a room while securing ventilation by having parts to be extended in parallel with each other with a space for ventilation, and providing a self-light-emitting body for emitting the light outside. SOLUTION: A room-inside shielding device 1 has a self-light-emitting body 2 extended like bellows. The self-light-emitting body 2 is formed of optical fibers, a heat generator or the like. The light emitted from the self-light-emitting body 2 includes a component having an outside directivity, and even in the case where a room-inside is brighter than a room-outside, the light from the self-light-emitting body 2 exists in front of the room-inside shielding device 1. With this light, the room-inside is hard to be seen from the room-outside, and the room-inside is shielded from the room-outside. Since the self-light- emitting bodies 2 are extended with a space, ventilation in this space part is secured. Consequently, cool air can be led into the room without using an air conditioner in summer and while seeing room-inside from room-outside can be shielded, and electric power can be saved.
