Title: Magnetic head driver
Inventor: KUNO HIROYUKI
IPC: G11B5/48
Filed: 1982-06-16
Abstract: PURPOSE:To prevent the oil evaporated from a bearing from leaking outside, by providing a magnetic fluid seal within a link path between a bearing storing inside space and a bearing storing outside space where a magnetic head exists to cut off the link path. CONSTITUTION:The seal main body 18a of a magnetic fluid seal 18 which encloses circularly a revolving shaft 13 is fixed at a bearing attaching part 11a of a bearing housing 11. The main body 18a contains a hollow cylindrical base 18b and two end plates 18c and set between a bearing 12 and a rotor 14. The inner fringe of the plate 18c is set close to the outer circumference of the shaft 13, and a colloidal magnetic fluid 18d obtained by dispersing the ferromagnetic fine powder into an oil solvent is flowed between the inner fringe of the plate 18c and the outer circumference of the shaft 13. Therefore the lubricating oil evaporated within the bearing 12 due to a rise of temperature of the bearing 12 which is caused by the continuous driving of a magnetic head slider 15 can be prevented from leaking outside since the inside of the bearing is shut off from the outside space by the seal 18.

Title: Manufacture of organic compound-plated steel
Inventor: OKA JIYOUJI
IPC: C23C14/14
Filed: 1978-08-26
Abstract: PURPOSE:To improve the corrosion resistance of steel sheet surface, by compund- plating of the surface of steel sheet with zinc and a plastic compound in a molecular state. CONSTITUTION:The surface of a steel sheet is cleaned successively by alkali degreasing, hot water washing, water washing, pickling, water washing, and drying, it is then put into a vacuum vessel, where it is treated by ion bombardment in Ar gas stream. Thereafter, pure zinc particles are heated in a tungsten resistance boat to be evaporated, simultaneously, a plastic compound, e.g., polyethylene, polypropylene, polycarbonate etc., is heated in another tungsten resistance boat to be evaporated. Hereby, compound-plating film composed of zinc and a plastic compound is deposited from the vapors on the surface of the steel sheet. The plating layer forms a semiconductor layer of combination of molecular zinc and a molecular plastic compound continuously from the surface of the steel sheet to the surface of the plating layer. Because the plating layer itself possesses semiconducting property without losing metallic properties in spite of having high insulating property over the whole layer, it is excellent in corrosion resistance as a sacrificial anticorrosion plating.

Title: Inner capacity measuring method for sample injection tube in total organic carbon meter
Inventor: KITAMURA HIROSHI
IPC: G01F17/00
Filed: 1995-04-27
Abstract: PURPOSE: To obtain a method for accurately measuring the inner capacity of a sample injection tube in total organic carbon meter. CONSTITUTION: After discharging solution in an injection tube 3e, a valve 8a is switched to the cleaning water container 18 side and a piston 8b' is pulled down from the uppermost part by means of a stepping motor 8d for syringe thus injecting a cleaning water into the syringe 8b. A slider 3a is then slid to communicate the injection tube 3e with a drain tube 3d or it is removed from the slider 3a and the valve 8a is switched to the injection tube 3e side. Subsequently, the stepping motor 8d is driven to elevate the piston 8b' thus injecting the cleaning liquid into the sample injection tube 3e. A CPU 8g detects the cleaning water being discharged from the sample injection tube 3e based on the operation of a keyboard 8h being carried out through a sensor 3c or visual observation of an operator. The CPU 8g counts the number of pulses being fed to the stepping motor 8d before the cleaning water is discharged and determines the inner capacity of sample injection tube 3e based on the number of pulses.

Title: Image signal processing circuit
Inventor: KOBAYASHI AKIO
IPC: H04N9/07
Filed: 1999-04-12
Abstract: PROBLEM TO BE SOLVED: To provide an image signal processing circuit that requires no revision of a capacity of a line memory depending on the resolution of a camera signal. SOLUTION: A memory 12 stores a camera signal each pixel of which has only one color component. A memory control circuit 14 reads the camera signal from the memory 12 above for each 1st pixel block. Line memories 16a-16d store the read camera signal of the 1st pixel block one by one line each, and a color separation circuit 18 applies color separation to the camera signal stored in the line memories 16a-16d for each 2nd pixel block. Thus, a camera signal each pixel of which has a plurality of color components is generated. Since the camera signal is read for each 1st pixel block in this way, the capacity of the line memories depends on number of horizontal pixels. Thus, it is not required to change the capacity of the line memories depending on the resolution of the camera signal.

Filed: 1988-04-27
Abstract: PURPOSE:To transmit data in a constant time regardless of the number of devices connected to a bus by having plural sequence numbers with one communication control device and obtaining plural transmitting rights for the cycle of one token. CONSTITUTION:A control circuit 23 adds +1 to the sequence number accumulated in storing means 3-0-3-n when two transmitting rights are obtained from a previous timeout to the next timeout, subtracts the inverse of 1 from the sequence number when one transmitting right is not obtained and the sequence number to be changed is registered into a storing means as the sequence number of the self-device. When the conditions, in which the number becomes the approximately equal interval in the system where the device belongs, are not satisfied, the sequence number to be changed is set to a token transmitting register 21 and plural transmitting rights are obtained at the approximately equal interval while the token circulates the logical ring once. Thus, regardless of the number of the devices connected to the bus, the data can be transmitted in the constant time.

Abstract: PURPOSE:To reduce the diameter of a rotary cylinder, by providing >=3 magnetic heads to the rotary cylinder and performing the recording and reproducing of a field with optional one of said magnetic heads and >=1/2 rotation of the cylinder. CONSTITUTION:Four magnetic heads are provided around a rotary cylinder with a phase of 90 deg.. With the first 3/4 rotation of the cylinder from the 1st state, the signals of a field are recorded or reproduced by a head 13. For other heads, a connection is broken to the signal line respectively while the head 13 is driven. Then the cylinder rotates by 3/4, and thus a head 15' records or reproduces the signals of the next one field on a video track 23. After this, the signals of a field are recorded or reproduced in the same way on each video track through heads 13' and 15 respectively at every 3/4 rotation of the cylinder. As the recording of a field is carried out at every 3/4 rotation of a rotary cylinder, the diameter of the cylinder can be reduced.
