Title: Erasure magnetic head
Inventor: INAGOYA OSAMU
IPC: G11B5/127
Filed: 1986-04-17
Abstract: PURPOSE:To surely erase the magnetic recording with inexpensive constitution by forming the upperstream side of an erasure gap of an erasure head by a magnetic material having a high saturated magnetic flux density and the downstream side by a magnetic material having a lower saturated magnetic flux density. CONSTITUTION:A magnetic material having a high saturated magnetic flux density is coated to a base 10 at the floppy disk upperstream side of an erasure gap 4 to form a magnetic film 11 and a magnetic material having a lower saturated magnetic flux density than that of the film 11 is used to the downstream side of the gap 4 to form a magnetic layer 12. Through the constitution above, the strength of the magnetism around the gap 4 sufficiently exceeds the strength Hs required for erasure and the attenuation of the magnetic field at the outside of the gap 4 is gradual, in other words, the distance between points M and N is long. When a magnetic medium passes through the part from the right toward the left, the medium is magnetically saturated between the points L and M, while passing through the points M, N, the magnetic hysteresis curve is gradually narrowed and finally converged to the point zero of the hysteresis curve. That is, the nearly complete erasure is attained.

Title: Controlling system for operation of air conditioner
Inventor: SATOU TAKAHARU
IPC: F24F11/02
Filed: 1984-05-07
Abstract: PURPOSE:To continuously keep stable temperatures even when one air conditioner in operation is out of order by a method in which the air conditioner is stopped when warning signal is inputted from the air conditioner provided with a centralized controller and at the same time the air conditioner being stopped is operated. CONSTITUTION:Under the condition that two air conditioners 2 and 4 are in operation, when the air conditioner 2 for example is in out of order and warning signal is sent out of the warning signal outgoing means of the air conditioner 2, the signal is put in the signal receiver 7 of a centralized controller 1 and then put in a stopped air conditioner selector 8. The supply of operation signal to the air conditioner 2 when receiving the signal by the selector 8 is soon stopped and at the same time operation signal for the air conditioner 4 being stopped is sent out. Since the air conditioner 4 being stopped can be soon operated even when the air conditioner 2 is out of order, the temperature of load space can be stably kept, thus permitting stable air conditioning to be performed.

IPC: B60J7/02
Filed: 1995-04-14
Abstract: PURPOSE:To assemble a roof frame yet simpler by constituting two guide channels so as to surround the driving element of a car roof frame with a cover, which is displaceable via the driving element extending in the axial direction and selectively opening or closing an opening part, alternately at the side varying in the axial direction. CONSTITUTION:Two guide channels 16 and 17 are made up of four partial openings 22, 23, 24 and 25, being reached to a frame from the side alternately varying, inclusive of a complete guide channel cross section, and continued in the axial direction. Among these partial openings 22 to 25 being reached to the frame in the axial length or the same direction of these openings, a section where a driving element 15 is exposed is selected as being dependent upon rigidity of this driving element to be used, so as not to be slipped out of both the guide channels 16 and 17 in the case of pressure received at a time when the driving element 15 has purposely displaced a cover. With this constitution, a complementary cover and a guide pipe become disused, and thus a car roof frame can be yet more simply and inexpensively manufactured and assembled.

Abstract: PURPOSE:To form a thin-film filter which is inexpensive and has excellent environmental resistance and high performance by constituting this filter of multilayered films formed by alternately laminating discontinuous metallic thin films formed as island shapes and dielectric thin films. CONSTITUTION:This thin-film spectral filter is composed of the multilayered laminates formed by alternately laminating the dielectric thin films 1 which have a dielectric constant epsilon1 and the metallic thin films 2 which have a dielectric constant epsilon2 and are formed as the island shapes on a dielectric substrate 7 of a prism type or plate type which is a base. As a more specific example, the filter is obtd. by forming the Ag thin film layers 2 by vacuum vapor deposition on the incident face of a prism (base) 7 of glass and heating the films after the vapor deposition by a heating method with radiation heat and trimming the shapes of the island-shaped Ag particles to a spherical shape. The SiO2 thin-film layers 3 are formed by sputtering vapor deposition in the upper part of the Ag layers and further, the Cu thin-film layers 4 are formed by vacuum vapor deposition thereon. The films after the vapor deposition are heated to trim the shape of the island-shaped Cu particles to the spherical shape. At this time, the multilayered laminate formed in such a manner is functioned as the thin-film spectral filter for incident light of a wavelength 0.8mum.

Abstract: PURPOSE:To continuously produce H2 in the presence of a metallic bipyridyl complex or a metallic porphyrin complex as a photocatalyst by using a specified water insoluble or slightly soluble electron donor and takng out only the oxidation product from the system. CONSTITUTION:In the production of H2 by a photochemical reaction in the presence of a metallic bipyridyl complex or a metallic porphyrin complex as a photocatalyst, a water insoluble or slightly soluble polymer contg. ascorbic acid, or ester or ether of ascorbic acid is used as an electron donor. The former is obtd. by reacting a polymer such as polyacrylic acid with ascorbic acid, and the latter is used singly or in combination with the former. The photochemical reaction is carried out in an aqueous phase system. Said compound is dissolved or suspended in water, and the reaction system is irradiated with light to generate H2. Said ester or ether of ascorbic acid is soluble in water, yet it is precipitated as a slightly soluble dehydrate in accordance with the progress of the reaction. The accumulation of the dehydrate reduces the H2 generating rate. By removing the dehydrate by filtration or other method and adding a fresh donor, the generation of H2 can be maintained. The separated precipitate can be easily regenerated with H2S.
