Title: Water purifier
Inventor: TAKAYAMA HITOSHI
IPC: C02F1/44
Filed: 1994-06-17
Abstract: PURPOSE:To detect the attachment/detachment of a cartridge stably for a long period of time and to eliminate a waterproof specification by constituting a detection mechanism part which detects the attachment/detachment of the cartridge with a magnet attached to the cartridge and a magnetic flux detection element which is installed in water purifier main body. CONSTITUTION:A water purifier is equipped with a discharge detection part 3, a measuring part 4, a power source part 5, a magnetic flux detection element 6, and a cartridge 2 which is installed attachably/detachably. The magnetic flux detection element 6 detects the attachment/detachment of the cartridge 2 from the change in magnetic flux density associated with the attachment/ detachment of the cartridge which is installed on a magnet 7. Since the attachment/detachment of the cartridge 2 is detected without contacting the cartridge 2, a water purifier car be used stably for a long period of time. Since a detection mechanism does not require a waterproof specification, a small-sized, inexpensive water purifier can be obtained. Besides, a measuring part 4 integrates the used discharge based on the output from a discharge detection part 3 and also integrates the installation time of the cartridge 2.

Title: Electrostatic latent image forming method
Inventor: TEJIMA AKITOMO
IPC: G03G15/22
Filed: 1978-11-05
Abstract: PURPOSE:To overlap two images easily and form a latent image, without using negative image, by exposing and charging a photoreceptor composed of three layers of dielectric, photo conductor and conductor by the specified method. CONSTITUTION:A conductive drum 1 covered with a dielectric layer 3 and a photo conductor layer 2 from the outer side forms a photoreceptor in three layers. This drum 1 is exposed wholly by a corotron 4 and initial charge is applied uniformly, then an electric charge of the reverse polarity of the charged charge of the layer 3 is trapped in the boundary of the layers 3, 2. When charged in reverse polarity of the initial charge while exposing the drum 1 with the original 7 by the corotron 5, the trap charge in the boundary of the layers 3, 2 is released in the light image bright part, and the charge on the layer 3 is neutralized, and charged in the reverse polarity. When the drum 1 is charged in the same polarity as the initial charge by a corotron 8 and exposed depending on the character or the like, the part of the layer 3 corresponding to the character or the like is charged in the same polarity as the initial charge. When the drum 1 is exposed on the whole surface in this state, the charge of moving part is adjusted, and a latent image of two images is formed.

Title: Production of polyester resin
Inventor: KUMAGAI YUUGO
IPC: C08G63/00
Filed: 1980-09-30
Abstract: PURPOSE: To obtain a polyester resin having excellent smoothness and mechanical properties, from a carboxylic acid, an alcohol or a hydroxycarboxylic acid and dimethylolpropionic acid.  
     CONSTITUTION: A polyester is produced by using at least one material selected from a carboxylic acid, an alcohol, a hydroxycarboxylic acid and esterifiable derivatives thereof and 0.5W30.0wt%, based on total material charge, dimethylolpropionic acid. If the materials are mixed so that the resulting mixture has carboxyl groups in excess of the hydroxyl groups, and the mixture is used to produce a polyester resin, the polyester can be obtained in the state in which unreacted carboxylic groups are dispersed in the molecule and the crosslinking sites are dispersed throughout the molecule, because dimethylolpropoinic acid serves chiefly as an alcohol component. With respect to the amount of dimethlolpropionic acid, an amount <0.5% is not preferred because of poor mechanical properties, and an amount >30wt% is not preferred because of decreased smoothness.

IPC: G02B13/18
Filed: 1995-05-12
Abstract: PURPOSE: To facilitate the manufacture of an aspherical lens having a small manufacturing error and prescribed performance and to reduce the cost of such a lens by composing the lens with a specified aspherical shape without using a higher order aspherical coefficient. CONSTITUTION: A lens 10 is a meniscus lens whose first surface 10a is convex, second surface 10b is concave and distance between lens surfaces is d(mm) and it is a single lens whose first and second surfaces 10a, 10b are formed with aspherical surfaces. The first and the second surfaces 10a, 10b are made to be aspherical shapes represented by the equation. In the equation, R represents the radius of curvature of a reference quadric surface of revolution (the first surface: R1 , the second surface: R2 ), K represents the conical coefficient of the reference quadric surface of revolution (the first surface: K1 , the second surface: K2 ) and (x) represents a distance between a ponit on the aspherical surface at the height (h) from the optical axis and a tangential surface passing through the vertex of the aspherical surface.  The radius of curvature R1 of the first surface 10a and the redius of curvature R2 of the second surface 10b satisfy the condition: 0<R2 /R1 <12.3. Consequently, the single lens forms the aspherical surface only by the conical coefficient without using the aspherical coefficient.
