IPC: G03G15/09
Filed: 1983-06-29
Abstract: PURPOSE:To obtain a cylindrical resin magnet which is subjected to anisotropic conversion sufficiently by using a die having a permanent magnet and a magnetic circuit including a yoke. CONSTITUTION:The die consists of rare earth cobalt magnets 31-33 magnetized radially around a cylindrical space 1 having a core 2 inside concentrically, magnetic field coils 41-43, and soft magnetic bodies 5, 6. A material made by adding polyamide resin to ferrite particles of 1mum average grain size and mixing at 250 deg.C is put in the die, and cooled and solidified at a temperature of 270 deg.C and at pressure of 70kg/cm<2>. It is formed, for instance, to outer diameter 30mm.phi, inner diameter 12mm.phi, and worked to outer diameter 24mm.phi. Thus, the distribution waveform of magnetic flux density shown in the figure is obtained.

Title: Search device of disk reproducer
Inventor: KONDOU KATSUFUMI
IPC: G11B21/08
Filed: 1984-06-08
Abstract: PURPOSE:To attain a search action in a short time and to eliminate useless movement to increase the lifetime of a disk reproducer, by calculating a shift amount between the present position and a target position after measuring the linear speed of a disk to obtain an accurate shift amount regardless of the linear speed of the disk. CONSTITUTION:For some of disk reproduction signals, the address data Tb on the present position B is read out by an address reading circuit 34 via a data control circuit 28 and stored in a time address data RAM33 via a serial/parallel conversion circuit 35. While the address data on a target position C is sent to a time address data RAM42 from a time data input device 40. At the same time, the pulses produced from an encoder 54 in response to the revolutions of a disk motor 11 are counted for a second by a counter 56 and converted into a linear speed by a rotational frequency/speed conversion circuit 46. This linear speed is stored in a RAM64. The data on RAM64, 33 and 42 undergo the arithmetic processing through conversion circuits 66, 82, 90 and 106 to obtain a number KC of kick pulses needed for shift between points B and A. Then an optical pickup 14 is driven via a kick pulse generating circuit 110 and a control circuit 18.

Filed: 1999-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a photocurable resin composition capable of providing a cured product having a low elastic modulus, and useful as a covering material for optical fiber, and further to provide a covering material for optical fiber. SOLUTION: This ultraviolet-curable resin composition comprising a urethane acrylate oligomer and a polymerization initiator is featured in the urethane acrylate oligomer having a polyoxyalkylene ether structure branched to three branches at least in the core part, in which each of the branched chain part of the structure has 2,500-10,000 number average molecular weight.

Title: Protective liner
Inventor: MAKINO SEIJI
IPC: F16D66/02
Filed: 1984-06-08
Abstract: PURPOSE:To enable the thickness of the liner in the abrasion process to be easily observed by sight, so as to carry out appropriate exchange of the liner, by forming blind holes on the mounting surface of the liner which comes in contact with the abrasion surface of the body to be mounted with the liner. CONSTITUTION:A liner 12 is mounted on the abrasion surface of the body to be mounted with the liner which may be worn outd by powdered particles, for protection of the surface. The main body of the liner 12 has a depressed part 14 on the mounting surface 13 which is the back side of the liner 12, except around its fringe. Plural blind holes 15 whose diameter decreases with its depth, are formed at a certain interval in the depressed part 14. The bottom 15a of the blind hole 15 is positioned in the middle of the thickness of the liner which is measured between the outer surface of the liner and the surface of the depressed part 14. Thus, when the amount of abrasion of the liner surface reaches the specified value W, the blind holes open up to the surface of the liner main body 12, and so the remaining thickness of the liner can be easily recognized by visual observation.

CONSTITUTION:In the one side/one pass welding of a thick steel plate of 50-80mm plate thickness, by using DC power source for a preceding electrode (L), by using AC power source for an intermediate electrode (M) and a succeeding electrode (T), high heat input submerged arc welding is executed with setting L-M distance between electrodes and M-T distance between electrodes corresponding to plate thickness such as 40mm/160mm L-M distance between electrodes 90mm/150mm M-T between electrode distance, etc., for 50mm plate thickness. Whereas the distance between electrodes is of the value measuring the distance between electrodes at groove bottom parts. By this method, one side/one pass welding of thick plate is performed without defect, the hand repair after welding is not required, improving efficiency of welding work.

Title: Multi-frame synchronization circuit
Inventor: YOSHIDA KAZUHIRO
IPC: H04L7/08
Filed: 1991-05-23
Abstract: PURPOSE:To attain re-synchronization immediately with the arrival of a frame synchronizing signal even when disturbance is caused to a clock and to attain re-synchronization in a short time even in a comparatively long multi-frame structure by resetting a frame counter with the multi-frame synchronizing signal and counting up the counter with a frame synchronizing signal. CONSTITUTION:A frame counter 21 is counted by a frame synchronizing signal and a binary code is outputted at output terminals 211, 212... and a frame number is sent to a decoder 16. In this case, a frame synchronizing signal is directly used for counting the frame counter 21 without use of a carry-out signal for each of 256 clocks from a bit counter 20. Thus, the frame counter 21 is surely counted with a synchronizing signal independently of the clock. Thus, for example, in the case of a long multi-frame constitution as 16 frames, even when out of synchronism is caused just after frame synchronization, only one frame time is required till re-synchronization.

Abstract: PURPOSE:To obtain a reliable kind of the title plasma X-ray source even with a highly frequent occurence of electric discharge, by receiving a plurality of members having plural gieces of ceramic capacitors arranged in a sandwiched fashion on a paralleleconductive plate in the bank of capacitors and then sealingly charging insulating oil therein. CONSTITUTION:The capacitors 2 in the bank of capacitors 1 are charged with electricity by means of a charging equipment (not illustrated). When an electric discharge switch 6 is made by impression of a desired voltage, electric discharge occurs between electrodes 9, 10 so that a large current of a high speed pulse is conducted. A plasma pinch thus occurs between the electrodes 9, 10 to cause generation of X rays 12 which are emitted through an x-ray takeout window 13 and thence through a mask 15 provided in a X-ray exposure. After the inside of the bank of capacitors 1 is vacuum exhausted insulating oil 18 is charged therein by means of a valve 17 until the oil liquid level reaches the position of an upper partition board 19. An oilproof rubber sheet is used as the partition board 19 whose upper part chamber ahs an insulating gas 21 such as nitrogen or SF6, etc. charged sealingly by means of a valve 20.

Title: Exposure scanning device
Inventor: KIMURA YOSHIMASA
IPC: G03G15/04
Filed: 1978-09-28
Abstract: PURPOSE: To enable vibrations and noise of the device to be prevented without impairing scanning speed by providing the means of controlling the driving force of a reciprocating means for exposure scanning so that the reciprocating means is driven at a low acceleration speed at the starting of backward movement after exposure scanning.  
     CONSTITUTION: As current is supplied to an electromagnetic clutch 12, a drive pulley 5 is driven to start exposure scanning. At this same instant, a braking gear 13 is driven. On the other hand, a brake drum 15 is revolved by way of a rotary clutch 14 to act braking power upon the drive pulley 5. Hence, the electromagnetic clutch 12 assumes a half-clutch state, as a result of which the driving power of the initial stage of driving becomes smaller than that in a steady driving state, thus it is accelerated at a lower acceleration rate snd the vibrations are small and are rapidly converged in a short approach section. In the backward movement, the one- way rotating clutch 14 disengages and therefore the brake drum 15 does not rotate.
