Title: Power saving method for data processor
Inventor: OKA TOSHIO
IPC: G06F1/32
Filed: 1993-05-11
Abstract: PURPOSE:To inexpensively attain power saving without using a CPU or the like equipped with a power saving validating function, or improving an OS or the like by recognizing the no-used state of an inputting and outputting device, transmitting a power saving mode signal to the other input and output controller, and disconnecting the power source of the inputting and outputting device connected with it. CONSTITUTION:When a key input from an inputting device, for example, a keyboard 10 and a mouse 11 or the like is detected by a processor 20, key information is analyzed. When the key input is absent, the time is compared with a monitor time set in a RAM 22, and when a key input signal 1 is absent in a prescribed time, the processor 20 generates a power saving mode signal 2, and transmits it to an other input and output controller 2a. Then, the display screen and the motor of a display device 15 and a file storage device 16 under control of the input and output controller 2a are turned off and stopped, so that the power saving control can be attained. Thus, the power saving control can be relatively inexpensively realized without adding a new circuit or device.

Title: Method for curing and drying monolithic refractory
IPC: C04B40/04
Filed: 1992-04-03
Abstract: PURPOSE:To sufficiently cause the reaction of a binder with water in a surface layer by applying a monolithic refractory into a frame mold and then coating the surface with a thin film with hardly any mass transfer with the air on a surface to be brought into contact with the air. CONSTITUTION:A monolithic refractory is kneaded with water and cast into a forming frame mold and the surface to be in direct contact with the air is coated with a thin film such as polybutadiene, polyvinyl chloride or an aluminum foil to prevent water added into the casting material from evaporating into the air. Thereby, the binding reaction of a binder near the surface to be brought into contact with the air with water is sufficiently developed to suppress phenomena of deterioration in strength and crumbling. Thereby, an alumina cement-based castable is cured and dried according to the subject method. As a result, apparent porosity can be reduced to improve the corrosion resistance by 20%.

IPC: G10D9/00
Filed: 1988-05-02
Abstract: PURPOSE:To improve the tone quality of the title music instrument by forming part of a resonance cover main body in the vicinity of an opened and closed valve of a metallic plate. CONSTITUTION:A keyed wind music instrument is constituted of a keyed blowing mechanism 10 and the resonance cover main body 20 made of a synthetic resin incorporating the mechanism 10 and the mechanism 10 is united with the cover main body 20 forming an air chamber 23 together with the lower cover section 21 of the cover main body 20. The lower cover section 20 united with the mechanism 10 is specially increased in strength and rigidity by means of the metallic plate 30 united to the cover main body 20 to one body. Therefore, when the valve is opened and the opening 4 of a chassis 1 is opened at the time of blowing this instrument, the sounds produced by a reed 3 and reflected by the metallic plate 30 or part of the sounds discharged from a discharging chamber 32 produce a lingering tone and penetrating feeling. Moreover, since the resonance cover has the metallic plate 30 formed almost over the full length of the cover main body 20 while it is principally composed of a synthetic resin, the sounds produced from this instrument have tone qualities and echoes reflecting the acoustic characteristics of the metal and synthetic resin. Thus the tone quality can be improved.
