Title: Air cleaner
Inventor: OMODAKA KATSUHIKO
IPC: B01D53/38
Filed: 1994-09-26
Abstract: PURPOSE: To inexpensively clean air in a wide range with cleaning, efficiency by providing the above air cleaner with a spraying section for ejecting water in a mist form in midway of air passage and removing the dust, smell components, etc., in the air by the misty water CONSTITUTION: The external air sucked from a suction duct by suction force of a Sirocco fan 10 passes the inside of the misty water ejected from the atomizing section 17. The water ejected at this time is segmented to fine grains by rotating sponge 18 and is ejected outside in the form of the mist by the centrifugal force generated by rotation. Since the he misty water is ejected under rotation, the air passage part in the suction duct 10 is eventually coated with the water over the entire part. The dust, smell components, etc., included in the air past this part are eventually mostly absorbed in the water and the air is cleaned. Since the leaning effect is executed by the misty water in such a manner, the air resistance is lower than that of a filter and the higher cleaning efficiency is obtd.  Since the air is sucked and discharged by the Sirocco fan 33, the air in the wide range is cleaned.

Abstract: PROBLEM TO BE SOLVED: To lengthen the sevice life of a contact point, and finely adjust a temperature by carrying an electric current to an electric heater by a semiconductor, making a case of metal, and transmitting heating by electric power consumption of the semiconductor to the case. SOLUTION: A hot water supply unit is composed of an electric heater 1, an aluminum die-cast case 12, a cover 4, a controller 13 and a thermostat A6, and in the thermostat A6, when a temperature is low, a contact point is closed, and a transistor 14 is turned on, and voltage of a high voltage battery 7 is applied to the electric heater 1, and water 3 is heated, and when a temperature of the water 3 becomes high, the contact point is opened, and the transistor 14 is turned off, and the water 3 is not heated. A temperature of the water 3 is adjusted to a temperature in the vicinity of a prescribed value by the above- mentioned repetition. Electric power consumption when the transistor 14 is thrned on becomes 20 W, but since it is installed in close contact with the aluminum die-cast case 12, heat is radiated, or is used for heating of the water 3.  Therefore, electric power can be effectively used, and the service life can be lengthened, and cost can be reduced.

Title: Magnetic head device
Inventor: UCHIKURA HIDEAKI
IPC: G11B21/21
Filed: 1990-08-31
Abstract: PURPOSE:To prevent a head core part from being attracted on a magnetic medium by forming cross-sectional shape which generates thrust to press and move a head core part to a magnetic medium side by the air current generated by the rotation of the magnetic medium on a suspension. CONSTITUTION:When the magnetic medium 3 is not rotated, a head core 1 is separated from the surface of the magnetic medium 3 by the spring force of the suspension 4. When the magnetic medium 3 is rotated, the air on the surface of the magnetic medium 3 flows by the viscosity of the air, which applies wind pressure to the suspension 4 arranged in the periphery. The suspen sion 4 is formed in blade shape partially, and the thrust is applied to the suspen sion 4 when the wind pressure is applied to the blade, and the head core approaches the surface of the magnetic medium according to the rotation of the magnetic medium, and the surface of the magnetic medium is kept in a slightly floated state. In such a way, no attraction between the head core and the magnetic medium occurs since they are kept in a non-contact state.

Title: Carriage having lift burden receiver
Inventor: FUJIKI TAKESHI
IPC: B62B3/06
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To provide a carriage having a lift burden receiver which can be smoothly lifted upon unloading of an article. SOLUTION: When an article 1 is mounted on a burden receiver 50 of this carriage, the load is dispersed longitudinally and transmitted to end members 30, 31. The burder receiver is descended against an ascent energizing means. The maximum load of the article 1 can be increased, due to this longitudinal load dispersion, while the longitudinally lengthy article 1 can also be supported without deflection. When the article 1 on the uppermost stage 1 is unloaded, the load is thus decreased. The burden receiver 50 is ascendant accordingly by the ascent energizing means. The next article 1 on the uppermost stage can be kept constant at level, or substantially constant. Braking action is generated during ascending by frictional resistance of an elastic member 64 of a sliding part. The burden receiver 50 can thus be ascended with slow speed.
