Title: Data transfer system
Inventor: NISHIOKA YOSHIKAZU
IPC: G06F13/12
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To shorten the occupation time of a bus with write to a magnetic disk device. SOLUTION: Data from a main storage device 2 are written through a bus 9 and a bus transceiver 6 into a dual port memory 5. At such a time point, the bus 9 is released. Next, the data written in the dual port memory 5 are read out and these data are written in a magnetic disk device 3. Since time for writing data into the dual port memory 5 is shorter than time for writing data into the magnetic disk device 3, the occupation time of the bus 9 is shortened.

Title: Method for improving water quality
Inventor: KOJIMA HISAO
IPC: C02F1/50
Filed: 1983-12-27
Abstract: PURPOSE:To easily perform the deodorizing, sterilization and pasturization of water, by providing a sub-line for supplying air to an aspirator to a liquid passing main line to which the aspirator and a stationary type line-mixer are arranged. CONSTITUTION:Drinking water is supplied under pressure from the upstream side of an aspirator 2.

The area of the incident luminous flux a1 to the photodetecting means 21 changes when the cylinder lens 4 is displaced in the optical axis direction R. The photoelectric conversion output of the photodetecting means 21 changes correspondingly and the position of the cylinder lens 4 can be detected in accordance with the change in the output of the photodetecting means 21. Namely, the light shielding quantity of the projected luminous flux changes and the quantity of the received light in the photodetecting part changes upon displacement of the 1st imaging optical system. The quantity of the received light corresponds to the position of the 1st imaging optical system 4. The position of the 1st imaging optical system 4 is easily and surely detected in this way.

Filed: 1987-09-30
Abstract: PURPOSE:To lower a friction coefficient at the time of a contact sliding with a disk and to obtain a high durability and a high reliability by specifying the surface roughness of the sliding surface of a slider. CONSTITUTION:A head 20 of a side 1 is equipped with a slider 10 having a sliding surface 10a in which a surface roughness Ra is 0.005mum or below. Thus, a dynamic pressure effect due to an air film generated between the sliding surface 10a at the inflow side of a disk 22 and the surface of the disk 22 is made comparatively large, and the sliding surface 10a at the inflow side of the disk 22 is made into a floating condition. Namely, magnetic heads 20 and 21 are made into a condition in which a force works to a disk 23 in a direction to separate from the disk surface. Consequently, the friction coefficient at the time of the contact sliding of the slider 10 is widely lowered, compared with the time of a perfect contact. Thus, the high durability and high reliability to the magnetic head and disk can be obtained.

Inventor: HATAKEYAMA YOSHIHIRO
IPC: H02H3/34
Filed: 1991-09-26
Abstract: PURPOSE:To block high frequency components generated from an inverter inserted for load control and eliminate the influence of the high frequency components upon a portion after a level discriminator by connecting a low pass filter to a zero-phase current transformer for detecting any ground fault current in AC cable way. CONSTITUTION:A low-pass filter 9 connected between a zero-phase current transformer 3 and a level discriminator 6 cuts off high frequency components and transmit only low-frequency components to the level discriminator. The low pass filter 9 blocks a carrier frequency and its harmonics as high frequency components, and should effectively pass the power source frequency components in delta grounding and the third harmonic components of an operating frequency and the power supply frequency in star grounding. When an inverter 10 is inserted at the load side, the waveform detected by the zero-phase current transformer 3 contains the high-frequency components; but the low pass filter 9 cuts off the high frequency components of the inverter, so that the waveform input to the level discriminator 6 has the commercial frequency of an AC cable way 1, and the ground fault detector operates without being affected by the high frequency components.
