Title: Exchanging method for routing information of internet router
Inventor: NAGASHIMA NORIMITSU
IPC: G06F21/62
Filed: 1994-09-22
Abstract: PURPOSE: To realize a route information concealment exchanging method whereby higher security is kept. CONSTITUTION: A route information transmission processing means ciphers route information as against a network which is selected and designated by a user from a route information table and also whose existence is required to be concealed or opened and transmits it to adjacent internet routers 11 to 13 by a broadcast mode as it is. Route information reception/register/updating processing procedure is decoded by presence or absence of ciphering from another internet router to a route information frame for receiving, is registered when it is not registered yet in the route information table and is updated by distance to a destination when it is already registered. In route information re-transmission processing procedure, ciphering is executed when a network attribute is 'concealment' as against route information of the route information table to be retrieved and transmission of route information to the adjacent internet routers is repeated as it is when it is 'open'.

Title: Device for controlling operation of refrigerating apparatus
Inventor: NAKAJIMA HIROTAKA
IPC: F25B1/00
Filed: 1992-08-27
Abstract: PURPOSE:To quickly dissolve the state of excess of the inverter current by a method wherein, when the inverter current has reached the upper limit, the inverter frequency is decreased in steps at specified intervals of time until the inverter current declines below the upper limit and, on the other hand, a switch-valve connected between the top of a receiver and the downstream line at an expansion mechanism is kept open for a specified period of time. CONSTITUTION:A refrigerant line 9 is formed with the interposition of a compressor 1 whose operating frequency is varied under the control by an inverter, a condenser 3, a receiver 4, an expansion mechanism 5, and an evaporator 6 in sequence; the top of the receiver 4 and the downstream line at the expansion mechanism 5 are connected by interposing a switch-valve SV. When the inverter current has assumed a state of excess and has reached a drooping level, a drooping-controlling means 51 controls the inverter frequency in a manner of decreasing it in steps at specified intervals of time until the state of excess of the inverter current is dispelled and, on the other hand, the switch-valve SV is kept open for a specified period of time. By this method a decrease in amount of the refrigerant in circulation and a decrease in the differential pressure between the high pressure and the low pressure can both be achieved and the inverter current is decreased below the drooping level quickly.

IPC: G11B7/09
Filed: 1982-12-28
Abstract: PURPOSE:To attain stable tracking also for a disc or mechanical system having eccentricity exceeding a moving limit by detecting the eccentric direction from the reference point of a turn table and calculating the shifted distances of the (x) and (y) axis directions from the peak value of tracking shift detected by the ordinary method to move the position of the disc.

Title: Magneto-optical recording medium and its reproducing method
Inventor: NISHIGORI KEIJI
IPC: G11B11/10
Filed: 1997-08-25
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for initialization magnetic fields and to obtain high resolution and reproduction characteristic of high performance by forming a magnetized film having the magnetic characteristic to shrink recording magnetic domains in a reproducing magnetic film. SOLUTION: A recording magnetic film 5 is formed as the perpendicularly magnetized film to hold the recording magnetic domains therein with a positive polarity and the reproducing magnetic film 3 is formed as the perpendicularly magnetized film having the characteristic to shrink the recording magnetic domains therein. The reproducing magnetic film 3 is slightly weak in its self-shrinkage force and the bonding force from the recording magnetic film 5 with an intermediate magnetic film 4 and the magnetization direction of its recording magnetic domains is directed to the negative direction. Intrinsically, the recording domains of the reproducing magnetic film 3 transferred from the recording magnetic film 5 are shrunk and the recording magnetic domains are not formed. Initialization is effected by this shrinkage action.  The recording magnetic domains of the reproducing magnetic film 3 are automatically annihilated by the shrinkage force at the time of reproduction and are not held in such a manner and, therefore, the magnetization direction of the reproducing magnetic film 3 is the same direction as a whole at the timing exclusive of the reproduction timing without utilizing a method, such as initialization magnetic fields.

Title: Developing device
Inventor: HASHIZUME HIROSHI
IPC: G03G15/09
Filed: 1988-09-13
Abstract: PURPOSE:To prevent the occurrence of leak and to reduce the cost of the title device by providing a magnetic flux generator which outputs magnetic flux to a developer carrier which carries magnetic developer inside a photosensitive drum. CONSTITUTION:An electromagnet 15 is provided by being opposed to a sleeve 2 inside the photosensitive drum 1. When the electromagnet 15 is excited, toner 5 carried in the sleeve 2 is attracted and made to soar to the electromagnet 15 to adhere to the photosensitive drum 1. At such a time, since the end part 15a of the electromagnet 15 opposed to the sleeve 2 is tapered, the magnetic flux is focused and intensive local magnetic field is generated in the direction of the sleeve 2. Therefore, the toner 5 is allowed to surely adhere only to the fine range of the photosensitive drum 1. Thus, the toner 5 is attracted toward the photosensitive drum 1 by the electromagnet 15 to adhere to the photosensitive drum 1 and high voltage is not impressed between the photosensitive drum 1 and the sleeve 2, so that the occurrence of the leak can be prevented and the reduction of the cost of the device can be accomplished.

Title: Detector of magnetic material
Inventor: MIURA TOKUNORI
IPC: G01V3/10
Filed: 1982-12-28
Abstract: PURPOSE:To reduce influence of the terrestrial magnetism and the external magnetic field due to iron or the like with a high sensitivity by providing an AC magnetic field generating means, an AC response-type flux gate magnetic sensor, and a phase difference detecting means. CONSTITUTION:When a sensor head part 3 of the AC response-type flux gate magnetic sensor is placed on the axis of a coil 1 in parallel with the face of the coil, the output of the sensor attains a zero because the horizontal components of the AC magnetic field generated by the coil 1 are the zero on the axis. When a magnetic material 9 approaches the coil 1, the distribution of the AC magnetic field generated by the coil 1 is disturbed by this magnetic material 9, and the horizontal components of the sensor head part 3 are not zero, and an output is generated from the sensor, and this output is allowed to pass through an amplifying part 4 and a frequency filter 5 to take out only components having the same frequency as the frequency Hz of the AC magnetic field generated by the coil 1, and they are rectified by a rectifying circuit 6 to display on a display part 7. Consequently, the influence of AC external magnetic field having frequencies other than the frequency Hz is reduced, and iron and a magnetic marker body are distinguished from each other because an induction magnetic field having a phase opposite to that of the magnetic material is generated for a conductor by an eddy current.

IPC: H01J61/32
Filed: 1986-09-26
Abstract: PURPOSE:To obtain a wide and uniform radiation surface by constituting a lamp in a spiral shape so that the inter-bulb distance at the lamp peripheral section is different and longer than the inter-bulb distance at the inside. CONSTITUTION:A ultraviolet light source lamp is constituted in a spiral shape so that the inter-bulb distance at the lamp peripheral section is different and longer than the inter-bulb distance at the inside. To unify the radiation illumination on the radiation surface, the shape and layout of an emitter are designed so that the radiation illumination at the center portion is decreased and the illumination at the peripheral section is increased. That is, the illumination at the peripheral section of the radiation surface is controlled by the radiation intensity at the peripheral section of the emitter, thus the inter-bulb distance at the peripheral section of the emitter is shortened to increase the luminous intensity, and the radiation illumination at the peripheral section of the radiation surface is increased relatively.
