Title: Fuel nozzle device
Inventor: KOTSUKAWA YOSHIHISA
IPC: F23D11/38
Filed: 1978-12-11
Abstract: PURPOSE: To enable a reliable sealing of a portion whereat a nozzle and a fuel passage are coupled together even if there is a expansion difference occurring due to a difference in temperature, by forming a seal member by employing a spring seal.  
     CONSTITUTION: A spring seal 12 is formed as a whole in a ring, consisting of a spring 12a whose cross-section is of a hollow circle, a core 12b which is situated at the inside of the spring 12a to prevent a deformation in the radiue direction of the spring 12a, and a covering material 12c which covers an outer circumference of the aforesaid spring 12a. The spring seal 12 is placed in a ring groove, bored in an end surface 2b, between an end surface 1b of a nozzle base 1a and the end surface 2b of a nozzle fitting part 2a of a housing, while the spring seal 12 is situated in a yielding condition between the said end surfaces. Where a difference in temperature between the nozzle fitting part 2a of the housing 2 and the nozzle 1 occurs for the  duration of burning and as a result there exists a thermal expansion difference between the two portions, a restoring force of the spring seal 12 follows to adapt itself  to the difference on account of its restitution force.

Title: High energy ray incident position detection element and device
Inventor: YAMAMURA KAZUHISA
IPC: H01L31/16
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To extend the lifetime of a detection element by a method wherein the thickness of a high concentration semiconductor region is set in the range of that of a semiconductor substrate. SOLUTION: By increasing a high concentration semiconductor region 3, the thickness of an effective high energy rays sensitive region 1' is decreased. When a pn junction interface is on a reverse face side, this is made away from a substrate face, and also a necessary reverse bias voltage is reduced, so that the lifetime of a detection element is prolonged. Incidentally, when the high concentration semiconductor region 3 is excessively thick, this provides adverse influences on the characteristic of the detection element inversely. From this viewpoint, a thickness d3 of the high concentration semiconductor region 3 is set to 1.8% to 93% of a thickness d1 of a semiconductor substrate 1, whereby performance of the detection element is enhanced, and the lifetime can be extended.

Title: Discharge device in magnetic field
Inventor: KAGEYAMA KATSUHIRO
IPC: H01J41/02
Filed: 1981-09-26
Abstract: PURPOSE:To obtain a crossed field discharge device in which the change of discharge status and the manifestation of discharge instability caused by the formation of a laminated layer are suppressed by providing, in the hollow section of the anode, a means that generates a magnetic field which is substantially parallel to its axial center core of an anode. CONSTITUTION:A cathode material is mostly caught by the inner surface of a substrate 11 that is not touching a group of electrons which maintains discharge and the side of a blade piece 12. Therefore, such an effect is obtained that the interaction between the said group of electrodes and laminated layer is restricted sharply and the nanifestation of discharge instability caused by the said interaction is suppressed. Besides, a part of the cathode materials laminated on the end face of the blade piece 12 and the inner surface of a connection material 14 is re-emitted to the space by the group of electrons. But since the greater part of the re-emitted material is caught by the inner surface of the substrate 11 of the said anode or the side of the blade piece 12, the accumulation of the cathode material on the end face of the blade piece 12 and the inner surface of the connection material 14 can be suppressed.

Title: Active matrix liquid crystal display element
Inventor: NAKAJIMA KOJI
IPC: G02F1/1337
Filed: 1990-06-11
Abstract: PURPOSE:To prevent a printing phenomenon and an after-image phenomenon from generating by providing a distribution film wherein liquid crystal molecules on the surface of a substrate are oriented at a 2-10 deg. tilt angle. CONSTITUTION:In an ON state, an electric field is applied between a transparent electrode 4 and a transparent electrode 5, so liquid crystal molecules 8a nearby the center of a liquid crystal layer 8 are almost perpendicular to the electrodes as usual. Liquid crystal molecules 8b nearby the substrate, on the other hand, are oriented almost in parallel to the electrodes, i.e. at a 2-10 deg. tilt angle to the electrodes under the influence of the orienting film 7. Consequently, even when an electric field which has the same intensity as before is applied from an electric conductor, the liquid crystal molecules 8c nearby the electric conductor 3 never enters a metastable state wherein they are at a different angle from the liquid crystal molecules 8b. No disclination is therefore generated. Consequently, generation of the printing phenomenon and after-image phenomenon can be prevented.

Title: Magnetron sputtering device
Inventor: FUJII SHINJI
IPC: H01L21/31
Filed: 1986-06-27
Abstract: PURPOSE:To improve the characteristic of step covering which is one of fine working by recessing the surface, opposite to a substrate to be formed with a film, of a target material for film formation of a magnetron sputtering device. CONSTITUTION:The substrate 2 to be worked is mounted to an anode 1 in a vacuum vessel. The recessed target 3 is provided on the front surface of a cathode 4 facing the anode and an electromagnet or solenoid coil 5 is provided to the rear of the cathode. The two electrodes 1, 4 are connected to a DC power source. An atmospheric gas of Ar, etc., is supplied under a low pressure through an introducing port 6 into the vacuum vessel and a glow discharge is generated between the two electrodes to convert the atmospheric gas to plasma. A magnetic field orthogonal with an electric field is generated near the target 3 by the electromagnet 5 and is confined to a high density in the space in contact with the cathode target 3. Since the top surface of the target 3 is recessed, the sputtering particles splashing from the target 3 deposit uniformly on the substrate 2 and the characteristic of the step covering is improved with good reproducibility.

Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To provide a charging connector with toughness against dusts and capable of communicating charging information between an electric vehicle and the charging connector with no influence of noises. SOLUTION: A light receiving part on the electric vehicle side has a light emitting element 24 and a light receiving element.

When the charging connector is mounted on the electricity receiving part, the brush 46 is dislocated backward, and thereby the light input/output part 17A is passed through the brush 46 and comes on the opened side of the element storing chamber 19. Then, the input/output part 17A is put opposite to the light emitting and receiving elements.  At this time, a contamination slightly attached to the light input/output part 17A can be removed by the brush 46.
