Title: Planar magnetic recording medium, manufacture thereof and magnetic recorder
Inventor: SUZUKI HIROYUKI
IPC: G11B5/64
Filed: 1990-03-16
Abstract: PURPOSE:To obtain high planar coercive force, and to contrive improvement in corrosion-resisting property by a method wherein the average arrangement period of the segregation region of elements, in connection with the direction along the surface of a magnetic film, is specifically prescribed. CONSTITUTION:Co-group alloy magnetic films 13 and 13', containing an element M, which is a single unit having a body-centered cubic structure, are formed on a substrate 11. Crystal grains of 2 to 30 nm in average arrangement period on the segregation region of the element M are provided in the direction along the surface of the magnetic films 13 and 13'. The element M is selected from Cr, Mo, W, V, Nb and Ta. To be more precise, when the segregation period of the element M is selected to 2 to 30 nm, the average arrangement period of the segregation region decreases, planar coercive force increases, and on the other hand, corrosion-resisting property, especially the decreasing rate of the saturation magnetization, which is obtained by corrosion- resisting test by dipping the material into aqua regia, decreases together with the decrease of the average arrangement period of the segregation region. As a result, a magnetic recording medium, having both high planar coercice force and excellent corrosion-resisting property, can be obtained.

Title: Amorphous silicon solar battery
Inventor: MISONOO MASAO
IPC: H01L31/04
Filed: 1985-03-28
Abstract: PURPOSE:To make it possible to obtain a high conversion efficiency, by determining the thickness of tin oxide constituting a transparent electrode within a specified range. CONSTITUTION:The thickness of a transparent electrode 3 comprising tin oxide is made to be 5,000-8,000Angstrom . Nor all of the photons, which are absorbed by an a-Si:H layer 15, contribute to photoelectric conversion. Certain percent of the photons is dissipated as the form of heat energy. The optimum thickness of the SnO2 film 3 is obtained from the wavelength dependence of a quantum collecting efficiency, which is the rate of the photons contributing to the photoelectric conversion. The value is 5,000-8,000Angstrom . When the thickness of the SnO2 film 3 is larger or smaller than this range, the photon absorbing rate is decreased. Therefore, in this method, the photon absorbing rate by an amorphous silicon layer can be made high, and the conversion efficiency can be made high.

Title: Memory control system
Inventor: KUSUMOTO KOUJI
IPC: G06F11/10
Filed: 1980-05-16
Abstract: PURPOSE:To obtain a normal data even though an error exists in both words of a doubled memory, by dividing each word within two memories into plural subgroups and then giving a check to the data with every subgroup. CONSTITUTION:No error exists at the byte position i (i=0-3) of a temporary register 3, and an error exists at the byte position i of a register 3'. In such case, a gate Gi opens by the data effective signal Si sent from a parity check circuit PCi, and a gate G'i is closed since the signal S'i of a parity check circuit PC'i is off. As a result, the output of Gi, i.e., a normal data is set at the byte position i of a reading register 5. In this case, the error detection signal ei of the circuit PCi is off. Thus an AND gate Gei is closed to deliver no error signal E to the system. The system has no breakdown as long as the position of the faulty subgroup differs and even though a fault exists in both doubled memories.

Title: Control device for air-conditioning device
Inventor: UCHIDA YASUO
IPC: F24F11/02
Filed: 1985-03-28
Abstract: PURPOSE:To operate the air-conditioning device properly and prevent the wasting of energy by a method wherein a detector, detecting the existence of personel, is equipped and the air-conditioning device is set in a low operation stage when there is no person in the room. CONSTITUTION:When there are personel in the room, the detector 20 is opened, the normally closed contacts (ra1), (ra2) of a switching relay RA are closed and the normally closed contact (ra3) is opened. Under this condition, the room is cooled or heated weakly when a strong button 12 is pushed. When there is no personel in the room, the detector 20 conducts an input terminal 23, therefore, the normally closed contacts (ra1), (ra2) of the switching relay RM are opened to make the operations of the strong switch 12a and a medium switch 13a ineffective. On the other hand, the normally opened contact (ra3) is closed and the effect is the same as a case in which a weak switch 14a is closed. Accordingly, strong or medium operating condition is switched to the weak operating condition when the strong switch 12a and the medium switch 13a are being closed while the condition may be held as it is when the weak switch 14a is being closed.

That is, since whether or not M, C, Y are to be recorded depends on the relation of 1-vk>=T'(i, j), 0-vk<T'(i, j), colors except black color is recorded at the remotest position from the recording of the black color. Thus, the color arrangement of each picture element is decided by giving the level of the vM, vC and vY.
