Title: Manufacture of two-layer medium for perpendicular magnetic recording
Inventor: OSAWA RYUJI
IPC: G11B5/667
Filed: 1988-12-09
Abstract: PURPOSE:To obtain a two-layer medium for perpendicular magnetic recording by depositing several layers of Co-Cr alloy having specific grain size. CONSTITUTION:Since the medium noise largely depends on the grain size of Co-Cr layers, the Co-Cr layers are formed in several processes with intervals for cooling to obtain the desired grain size. When the grain size is 500Angstrom  or less, a two-layer medium having high sensitivity and high CN ratio can be obtained. For example, a 0.5mum thick NiFe film is formed on a 50mum thick polyimide film by RE sputtering, and then a 0.15mum thick Co-Cr film is formed with specified sputtering pressure and power. The medium is cooled by Ar gas and the second layer of Co-Cr with 0.15mum thickness is formed under the same conditions as the first layer.

Title: Rotation controller for grain feeding valve in grain dryer
Inventor: KOJIYOU REIJI
IPC: F26B17/14
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To prevent high moisture content grains from clustering in a feed valve by controlling stoppage and forward/reverse rotation of the feed valve based on the discharging position of a scooping port 11 detected by a position sensor thereby preventing overdrying of the grains. SOLUTION: Grains in a drying chamber 8 on one side are scooped at an upper position by a scooping port 11 by driving a feed valve 12 forward. Position for discharging grains at the lower part is detected by a position sensor 14 and grains are discharged by stopping the scooping port 11 at a lower discharging position. Subsequently, grains in the drying chamber 8 on the other side are scooped at an upper position by the scooping port 11 by driving the feed valve 12 reversely. Position for discharging grains at the lower part is detected by the position sensor 14 and grains are discharged by stopping the scooping port 11 at a lower discharging position. The operation is repeated and grains in the left and right drying chambers 8 are circulated repeatedly and exposed to hot drying air in the way of flow down and dried up.

Filed: 1990-11-15
Abstract: PURPOSE:To attain sound collection with less sound filled inside and high articulation even when a sound source is placed in the vicinity of a microphone by estimating a distance of the sound source depending on a level difference of outputs of plural microphones and controlling an equalizer to control the frequency characteristic so as to reduce the near effect. CONSTITUTION:A signal IS1 from a microphone 1a connects to one input of a level ratio calculation section 3. The signal is subjected to logarithmic compression by a logarithmic amplifier 4a able to process a bipolar signal and a signal LS1 proportional to the logarithm of the signal level by a full wave detector 5a and a smoothing circuit 6a. Similarly, a signal IS2 from a microphone 1b is a signal LS2 processed by a logarithmic amplifier 4b, a full wave detector 5b and a smoothing circuit 6b. The signals LS1, LS2 are fed to a subtractor circuit 7, in which the difference signal DS of the both is obtained. The difference signal DS is proportional to the logarithm of the ratio of the absolute value of the input signals IS1, IS2. The difference signal DS passes through an absolute value circuit 8 and fed to a clamp circuit 9. When the sound source is close to the microphone, the level ratio signal RS is increased and the emphasis of the low frequency due to the near effect is reduced.
