Title: Parallel operating power unit
Inventor: UEMATSU HIROHARU
IPC: G05F1/10
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To provide a technology which generates variation in output voltage resulting from the replacement of a power source board having got out of order when reliability is improved by parallel operation. SOLUTION: A diode 12 for isolation is connected behind a smoothing capacitor 11 of a DC/DC converter 10 and then when the power source board having got out of order is detached and a substituting power source board is connected, the drop of the output voltage is eliminated by eliminating the charging for the smoothing capacitor of the substituting power source board by the power source board in operation. Consequently, a load device can be prevented from malfunctioning.

Title: Dust removing filter for air conditioner
Inventor: ONOZAWA MASAHIRO
IPC: F24F13/28
Filed: 1990-01-18
Abstract: PURPOSE:To impart long use life by arranging filter passages composed of a filter element and lattice-like opening passages each having a side wall formed thereto from a fiber capable of electrostatically attracting dust. CONSTITUTION:A filter 10 consists of filter passages 14, lattice-like opening passages 16 and the partition plate parts 18 arranged between these passages and these constitutional elements are formed from the same nonwoven fabric. The flat surface of the nonwoven fabric is arranged to each of the filter passages 14 so as to cross an air passing direction and arranged to each of the opening passages so as to become parallel to the air passing direction. The nonwoven fabric can electrostatically attract dust in air by the action of its electret fiber and dust is removed from air in the filter passages 14 and the lattice-like opening passages 16 by electrostatic attraction action. By this method, a fiber wt. basis can be increased without increasing pressure loss.

Title: Blowoff device for air conditioner
Inventor: TAKAHASHI YUTAKA
IPC: F24F13/06
Filed: 1980-01-23
Abstract: PURPOSE: To uniformalize a temperature distribution in a room and to improve comfortableness  at an air-conditioning time, by a method wherein a blowoff direction of an air-conditioning flow is  automatically clanged by a magnetic action.  
     CONSTITUTION: A temperature-sensing magnet 12, whose quality changes into a magnetic object  or nonmagnetic object depending on a temperature, is located between a floating magnet 10 and a  stationary magnet 11. In the event of cooling or in case temperature of air flowing into a blowoff  device is low, and when the temperature-sensing magnet 12 becomes below the Curie point, a  permanent magnet forms a magnetic circuit as shown in lines of magnetic force 14 and 15 passing  through the temperature-sensing magnet 12. Thus, the floating magnet 10 is sucked to the stationary magnet 11, and simultaneously, a control plate 8 rotates to become horizontal. A flow F 1 ,  flowing into the blowoff device 11, forms a flow F 2  above the control plate 8 and a flow F 3  below  the plate 8, and they join at the downstream side of the control plate 8 to form a horizontal flow  F 4  which discharges from a blowoff port 7. When the temperature-sensing magnet 12 becomes  above the Curie point in the event of heating, it changes to a nonmagnetic object, and the floating magnet 10 and the stationary magnet 11 repel each other. As a result, the control plate 8 inclines,  and the flow F 1  forms a downward flow F 7  to uniformalize an indoor temperature.

Abstract: PURPOSE:To improve visual graininess by incorporating a nondiffusible coupler reacting with the oxidized product of a color developing agent and releasing a diffusible dye properly oozing the dye, and a monodispersed silver halide emulsion in at least one of emulsion layers. CONSTITUTION:When a dye diffusion type coupler is used, a dye diffuses to the circumferences, resulting in forming a dye distribution low in concn. but large in area in a dye cloud, and overlapping each cloud and thinning graininess of a low frequency part. When a monodispersed silver halide smulsion is used here, a size distribution of the diffusion type dye clouds become small, large mottles becomes invisible, and visual graininess is improved. As the dye nondiffusion type coupler, one represented by formula I is used in which Cp is a coupler component properly oozing a dye image; X is a component combining with a coupling site and releasable upon coupling reaction with the oxidized product of a color developing agent, and having a 8-32 C group; and (a) is 1 or 2. A coupler represented by formula II is used for a dye diffusion type coupler.

Filed: 1995-01-20
Abstract: PURPOSE: To continuously produce alkadienols in high conversion rate and selectivity by reacting a conjugated alkadiene with water in the presence of a palladium-phosphorus catalyst and carbon dioxide. CONSTITUTION: The reaction in the former stage is carried out by keeping the molar ratio of a conjugated alkadiene to an alkadienol at >=0.7 in a completely mixing type reactor and the reaction in the latter stage is then conducted by keeping the molar ratio of the conjugated alkadiene/alkadienol at <=0.55 in the completely mixing type reactor and the molar ratio of water/conjugated alkadiene at >=2. The residence time of the reaction in the former stage is kept longer than that of the reaction in the latter stage.  Thereby, the reaction in a high selectivity is carried out by keeping the molar ratio of the conjugated alkadiene/alkadienol in the reaction in the former stage at >=0.7 and the formation of by-products can be suppressed to raise the selectivity as a whole by keeping the molar ratio of the conjugated alkadiene/alkadienol in the reaction in the latter stage at <=0.55 and the molar ratio of the water/conjugated alkadiene at >=2.
