IPC: B41J2/335
Filed: 1988-02-18
Abstract: PURPOSE:To improve printing density irregularity, to enhance not only heat generating efficiency but also heat response and to conserve power, by partially flattening the upper part of a heat generating resistor or abrasion resistance layer. CONSTITUTION:A common electrode 3 composed of a conductor electrode and an electrode group, wherein individual electrodes 4 are provided at a dot pitch interval, are provided on a substrate 1 provided with a glaze layer 2 and heat generating resistors 5 are printed on the opposed parts of the common electrode 3 and said electrode group in a line form to be backed and a glass layer is printed and baked so as to partially cover the resistors and the electrode group. The surface of the protruding glass layer on each of the heat generating resistors is polished to form an abrasion resistance layer 7 whose upper part is flattened. Pulse voltage is applied to the heat generating parts formed between the common electrode 10 and the individual electrodes 4 for an arbitrary time and the resistance values of the respective heat generating parts are separately adjusted to uniformize the resistance values of all of the heat generating parts. The upper parts of both of the heat generating resistors and the abrasion resistance layers are uniformly formed and a definite quantity of heat is conducted to thermal paper to improve printing density irregularity and, since the contact part with the thermal paper is flat, the contact of the paper with the heat generating parts becomes well, and heat generating efficiency and heat response are enhanced.

Title: Vacuum vessel for fusion reactor
Inventor: TADA EISUKE
IPC: G21F3/00
Filed: 1993-02-25
Abstract: PURPOSE:To enhance mechanical rigidity or shield performance by employing a double wall structure vessel for confining plasma, arranging a plurality of ribs between the double walls, and filling the space between the double walls with a neutron shielding element. CONSTITUTION:The vacuum vessel has a double wall structure of inner and outer walls 10, 11 coupled integrally by means of a plurality of troidal ribs 12 and 13. The space defined by the inner and outer walls is filled with multiple spherical neutron shielding elements composed of a nonmagnetic material, e.g. an austenite based stainless steel. A plurality of through holes and irregular parts are made in the plate face of each rib 12, 13. Since a thin plate can be employed for the wall 10, 11 without significant sacrifice of overall mechanical rigidity, circumferential electric resistance of the wall itself can be increased in the troidal direction. Since the element 14 has small diameter and a dielectric layer of Al2O3, for example, is applied to the outer surface thereof circumferential resistance of shield layer is increased in the troidal direction and the element 14 can be treated as a dielectric part.

Title: Vertical magnetic recording and reproducing head
Inventor: FUJISAWA IKUO
IPC: G11B17/32
Filed: 1984-02-28
Abstract: PURPOSE:To prevent wear by providing a slider incorporated with an auxiliary magnetic pole, projected by a prescribed size from a face of the auxiliary magnetic pole opposing to a recording medium, in contact with the recording medium and having a lubricating operation so as to decrease the wear resistance between the both while adopting the system keeping a gap between the recording medium and the auxiliary magnetic pole. CONSTITUTION:A gap G is kept constant by providing incorporatedly the slider 9 having a sliding face 8 projected by a size (d) from a medium opposing face 7 of the auxiliary magnetic pole 3 in contact with the recording medium 2 to both sides of the auxiliary magnetic pole 3. The slider 11 is formed by a solid lubricant so as to provide lubrication and a solid impregnated with a lubricant oil such as oil-bearing metal or oil-bearing plastic is used as the solid lubricant. Since the sliding face 12 of the slider 11 having the lubrication like this contacts the recording medium 2, the wear resistance between the both is decreased and damage due to wear is prevented for the both and the service life is extended. Since a protection film is formed by the oil from the slider 11, the recording medium 2 is not damaged even if the auxiliary magnetic pole 3 contacts therewith.

Title: External memory device
Inventor: UMEGAKI SUNAO
IPC: G11B17/22
Filed: 1986-02-20
Abstract: PURPOSE:To obtain an external memory device storing plural low cost media while a signal cable between a read/write mechanism and a carrying mechanism is eliminated by providing a light emitting section sending a data coding the internal state of the read/write mechanism in the vicinity of the read/write mechanism and providing the light receiving part of the data sent from the light emitting part in the carrying mechanism. CONSTITUTION:The read/write mechanism 3 is mounted on a prolonged line of a storage case 1 and has the light emitting part 4 at the side facing the carrying mechanism 2 and the carrying mechanism 2 has the light receiving part 5. In positioning the carrying mechanism 2 to put in/take out a medium to/from the read/write mechanism 3, the light emitting part 4 and the light receiving part 5 are faced, the carrying mechanism 2 uses the light receiving part 5 to detect the information sent from the light emitting part 4 so as to discriminate whether or not the medium 6 is put in or taken out of the read/write mechanism 3. Since the carrying mechanism 2 receives only the information of the placed read/write mechanism 3, even when plural number of read/write mechanisms 3 are mounted, only the information of the read/write mechanism 3 at a location positioned at that time is read. Thus, a circuit selecting the information sent from the plural read/write mechanisms is not required for the control section of the carrying mechanism 2.

Abstract: PURPOSE:To improve tracking capacity, disturbance resistivity, workability for assembling, etc. by regulating the moving direction of an optical pickup to the tracking direction by using a pin as a fulcrum by a rocking means in the following-up operation of a driving mechanism. CONSTITUTION:Guide rails 20 and 30 are set in parallel with a tracking direction A, and the first carriage 10 is guided by guide rails 20 and 30 and is freely moved. An optical pickup 40 is constituted as one body together with a movable coil 15 of a linear motor, and a linear motor yoke 16 is set in parallel with guide rails 20 and 30. In case that the first carriage 10 is stopped and held in a desired position, an electromagnet 70 is turned on. Then, a plate 71 is bent by the magnetic attraction and is brought closely into contact with the electromagnet 70. Thus, the carriage 10 is held fixedly to the plate 71 as an immobile member. In case that the following-up operation to match a minute spot from the optical pickup 40 to a track on an optical disc is performed, the movable coil 15 is moved by a minute extent after the first carriage 10 is stopped and held in a desired position by a positioning means.

Title: Missfire detecting method for gasoline internal combustion engine
Inventor: AKASE YOSHIAKI
IPC: G01M15/04
Filed: 1991-03-04
Abstract: PURPOSE:To ensure the judgment of missfire without the effect of the driving state of an engine. CONSTITUTION:The deviation between the average value and the maximum value or the minimum value in the period wherein there is the detected signal from an engine-rotating angular-velocity sensor 2 is obtained by a CPU 32. When the deviation exceeds a judging value, missfire is judged. At this time, a continuous missfire judging circuit is changed based on the engine driving state. In this way, the number of the missfire judgements is increased under the driving state wherein the judgement is difficult, and the number of the missfire judgments is decreased under the driving state wherein the judgment is easy. Therefore, the missfire can be positively judged under all driving states.
