Title: Manufacture of magnetic recording medium
Inventor: HIBINO KUNIO
IPC: G11B5/84
Filed: 1990-11-06
Abstract: PURPOSE:To prevent the deterioration of the electromagnetic conversion characteristic and to improve the practical characteristic by winding a film inside a magnetic recording medium which film shows the same or larger thermal shrinkage as or than the magnetic recording medium after annealing when the medium is wound around a cylindrical bobbin and annealed after a heat load process. CONSTITUTION:This recording medium is formed of a high polymer film 1, a magnetic recording layer 2 of a ferromagnetic metallic thin film, a protecting film layer 3, a lubricant layer 4 and a back coating layer 5. When the medium is wound around a cylindrical bobbin 6 for annealing after a heat load process, a film 8 equivalent to or higher than the magnetic recording medium 7 to be produced is wound inside. Therefore, the elasticity and thermal shrinkage of the film 8 can relieve that the recording medium 7 is tightened consequent to the thermal shrinkage of the recording medium. The transfer of the shape of the rear face of the magnetic recording medium 7 can be prevented. Moreover, the damage to the surface of the magnetic recording layer 2 by the foreign substance caught during the process can be removed.

Filed: 1989-11-22
Abstract: PURPOSE:To reduce energy consumption in an inactive state by providing a function block to turn an output circuit, which is selectively turned to an operating state corresponding to an operation mode and coupled to an external terminal when the circuit is set in an unoperating state, to a high output impedance state. CONSTITUTION:The output step of a digital output circuit DOB8 constitutes a totem pole type output circuit and the base of a transistor T1 forming a high-level output signal is connected to the output terminal of a CMOS inverter circuit. Then, the source output of an MOSFET Q4 is supplied to the base of a transistor T2 forming a low level output signal. In such a digital unit output circuit UDOB, when an enable signal E is set to a high level, a P-channel MOSFET Q1 is turned to an OFF state and the base currents of transistors T1 and T2 are interrupted. Therefore, an output terminal OUT is turned to a high impedance state and current consumption can be made zero.

Title: Automatic bath device
Inventor: HAMADA MAKOTO
IPC: F24H1/00
Filed: 1986-12-18
Abstract: PURPOSE:To prevent the faulty detection of a pressure sensor and improve the durability of the title device, by a method wherein the pressure sensor is provided so as to be communicated with a circulating pipe in a main body and air in the circulating pipe communicated with the pressure sensor is purged with a proper time interval upon supplying hot-water, fallen through a hot-water supplying pipe, while air-purge is omitted after the pressure sensor has detected a water level higher than the connecting part of the circulating pipe and a bathtub. CONSTITUTION:When the water level of a bathtub 4 is lower than the connecting part of a return pipe 9 and a bathtub 4 or a bath adaptor 19, water in the return pipe 9 is replaced some times with air depending on a piping condition from a main body 1 to the bathtub 4. Therefore, the transporting path of hot-water is switched to the side of the return pipe 9 with a proper time interval and air is purged so that the air will never be interposed in the path from a pressure sensor 11 to the bathtub 4. When the pressure sensor has detected a water level LB higher than the bath adaptor 19, the sequence of air purge in every given times is cancelled thereafter and the sampling of the outputs of the pressure sensor 11 is effected continuously while transporting the hot-water to the bathtub 4 through a forwarding pipe 8.

Title: Beam index type cathode-ray tube
Inventor: IWATA KOZO
IPC: H01J29/34
Filed: 1986-12-18
Abstract: PURPOSE:To uniformize a color balance and to eliminate a color phase shift during regeneration of a color image by selectively mixing a phosphor stripe with a phosphor which has color emission dissimilar to that of a phosphor stripe wherein a second index phosphor is mixed. CONSTITUTION:While a fixed amount of blue luminous phosphor alphaB is mixed with a phosphor stripe R so as to form a phosphor stripe (R+alphaB) in a phosphor film 10, a fixed amount of red luminous phosphor alphaR is mixed with the phosphor stripe B so as to a phosphor stripe (B+alphaR). The respective amounts of phosphors alphaB and alphaR mixed in these stripes R and B are regulated so that blue and red luminous amounts during regeneration of red and blue images are nearly similar to the luminous amount of green luminous amount in a phosphor stripe (G+Gi). Even if regenerated red images during regeneration of color images are uneven on portions (I) and (II) corresponding to the stripes (B+alphaR) and (G+Gi), the blue luminous amount wholly rises to uniformalize a color balance since the phosphor B exists mixedly in the stripe (R+alphaB).
