Title: Magnetic disk
Inventor: KAWAKAMI HIROJI
IPC: G11B5/73
Filed: 1986-09-12
Abstract: PURPOSE:To obtain a magnetic disk which is less damaged by the collision of a head and disk at a low cost by forming a substrate of a sintered body of an inorg. compd. and forming an underlying layer of a molten and solidified material essentially consisting of a silicon compd. CONSTITUTION:A ceramic material which can improve a sliding resistant characteristic is used as the substrate 1 and a glass layer is formed on the ceramic base body in order to fill the surface ruggedness of the ceramic material and to facilitate polishing of the surface. A recording medium 3 is deposited on the glass layer as the underlying layer 2. Since the glass underlying layer 2 is harder than the underlying layer of Ni-P, etc., used heretofore, said layer prevents the deformation of the recording medium when the head collides against the medium. The damage of the recording medium is thereby prevented as well. The ceramic substrate holds the glass layer so that the splashing of the glass layer is prevented even if fine cracks are generated in the glass layer.

Abstract: PURPOSE:To stably carry out operation by providing a vent pipeline leading to the upper part of a furnace casing, furnishing a control valve to the pipeline, and further providing temp. and pressure detecting means in a protective cover. CONSTITUTION:Molten slag is dropped into a cooling water tank 10 from a tap hole 2 through a space in the protective cover 3, and the gas in the furnace is simultaneously injected into the space in the protective cover 3 from the tap hole 2. The injected gas is returned to the upper part of the furnace casing 4 through the vent pipeline 5 provided with the control valve 6. The opening of the control valve 6 is adjusted so that the amt. of the air supplied from a tuyere 11 and supplied to the upper part of the furnace casing 4 is maximized to increase the combustion quantity, and also adjusted to minimize the amt. of the gas to be injected. The furnace temp. decreases as the amt. of the air supplied from the tuyere 11 decreases, and the tapping amt. is also decreased. When the tapping amt. becomes lower than a set value, the opening of the control valve 6 is adjusted by a control means 9, and the amt. is controlled.

Title: Method and device for controlling radio band
Inventor: NUNO FUSAO
IPC: H04L12/28
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To reduce bands and delay time necessary to control for performing a radio band allocation request for a radio channel. SOLUTION: A radio band allocation request and band allocation processing are repeatedly executed through a polling method by repeatedly executing steps S20 to S22 when the request value of a radio band allocation request issued from a radio terminal station is not '0' and transmission data exists in the radio terminal station. In the case, the transmission data is processed and does not exist any more in the radio terminal station and the request value of the radio band allocation request to a radio base station becomes '0' (step S20: YES), the radio base station counts the number of receiving times of the request value '0', and when the number of the receiving times reaches a threshold (step S24: YES), the radio base station shifts a radio band allocation request method from a polling method to a random access method.
