Title: Coil bobbin for electric machine
Inventor: MATSUBARA SHINICHI
IPC: H02K3/46
Filed: 1985-02-26
Abstract: PURPOSE:To enable coils wire to be wound up in a well-ordered form without leaving space between coils and ring corner sections, by forming a step section extending on the full periphery integrally in the ring corner section on the winding start side of the coils on a coil bobbin. CONSTITUTION:On a coil bobbin 1 consisting of a cylindrical shell section 1a and a ring flange section 1b, a step section 5 is formed in the ring corner section between the shell section 1a and the flange section 1b. The step section 5 is set so that the salient height h in the radial direction may be equal to the wire diameter of coil wires 2. The width W in the axial direction is contrived to be set so that it may be smaller at a winding start position 1d-S and may be almost equal to the coil wire diameter at a winding end position 1d-e. In this manner, a space between the first layer of the coil wires 2 and the flange 1b is avoided, an so the second layer and the following layers can be also wound up in well-ordered form with coil wires.

Title: Electromagnetic shield structure for cathode-ray tube face
Inventor: TAKASE KATSUHISA
IPC: H01J29/00
Filed: 1991-02-05
Abstract: PURPOSE:To enhance the electromagnetic shielding effect of the surface of a CRT face plate without causing thickening of a transparent electroconductive film, which is attached to the surface of the CRT face plate. CONSTITUTION:A metal foil tape 6 is affixed in a scope till an anti-explosion band 5 from the peripheral part of a transparent electroconductive film 4, which is attached to the surface of a CRT 1 face plate, and this band 5 is grounded. When in this condition the resistance value between two arbitrary points on the face plate surface is measured, it gives the resistance value between each metal foil tape 6 and measuring point accordingly. This lessens the resistance value of the face plate surface compared with the case in which no metal foil tape 6 is attached (where the resistance value of the whole surface will be measured), which should increase the electroconductivity and enhance the electromagnetic shielding effect.

Title: Manufacturing method of image pickup tube
Inventor: NOBUTOKI SABUROU
IPC: H01J9/20
Filed: 1979-03-30
Abstract: PURPOSE:To improve signal characteristics of a image pickup tube by bonding a transparent thin glass plate with preset thickness on a striped filter surface of a transparent face plate, abrading the area between the filter and glass surfaces over the distance not exceeding the preset length, and reducing its gap against a photoelectric conversion surface. CONSTITUTION:A transparent thin glass plate at a thickness of 40-80mu is sealed on the color separation striped filter surface and is abraded. A distance from a striped filter surface to the abrasion surface is set to less than 40mu only by finishing abrasion. An epoxy resin is most suitable for bonding the transparent thin glass plate. This plate is bonded on a photoelectric conversion surface of a image pickup tube. Since this permits reduction of the gap between the photoelectric conversion surface and the striped filter, the striped filter image on the photoelectric conversion surface becomes clear and the quantity of the color television color signal can be increased.

Title: Data transmission processor in vehicle
Inventor: INA KATSUHIRO
IPC: H04L12/40
Filed: 1987-02-20
Abstract: PURPOSE:To constitute a system in a reliable state by making transmission requests sequentially circulate through respective stations connected to a network. CONSTITUTION:The access number of a computer for control selected as a master station 51 is set to '0' and the access numbers of the computers for control which are set as other plural slave stations 521, 522... are sequentially set from '1'. And the each slave station, in the case of requesting the transmission with the access number, transmits a next access number obtained by adding '+1' to its own access number to the network and gives the transmission request to the next order slave station. When the slave station corresponding to the access number does not exist, the master station detects it and the access number is updated to the next number to be transmitted as the transmission request, so that the action of assigning the transmission request can be updated. Thus, the transmission request circulates through the respective stations within the range of the shortest time and the control of data transmission is effectively executed in the reliable state, then the data is mutually exchanged among the plural computers for control in a vehicle.

IPC: G01N33/28
Filed: 1983-03-07
Abstract: PURPOSE:To determine the cause of deterioration of oil by measuring its trasient characteristic, by detecting the temperature of the oil by an oil-temperature detecting means when the oil to be measured has a specified temperature, and applying a pulse voltage to a pair of electrodes in the oil. CONSTITUTION:When an oil to be measured has a specified temperature, the temperature of hot water is detected by a hot-water-temperature detecting means 2, and a pulse voltage is applied to at least a pair of electrodes 1 provided in the oil from a power source means 3. A current, which flows through the electrodes 1 in correspondence with the property of the oil between the electrodes 1, is detected by a current detecting means 4, and the change in current is measured by a processing means 5. The measured value and the performance of the oil are displayed on a display means 6. The performance of the oil is measured from the transient response of the oil when the pulse voltage is applied. Thus the driver himself can know the present state of the engine oil, i.e., the deteriorating state of the oil. This is useful for the safety of an automobile, improvement in fuel consumption rate, and the like.

Abstract: PROBLEM TO BE SOLVED: To provide a method for alignment which is capable of exactly and stably aligning a magnetic head for generating magnetic fields and an optical head for irradiation with a light beam and an apparatus for alignment. SOLUTION: While an objective lens 4 of an optical pickup 3 is moved back and forth so as to move the focusing position of the light beam back and forth in a direction perpendicular to the surface of the magnetic head 2 near the surface of the magnetic head 2, the magnetic head 2 is irradiated with the light beam from the optical pickup 3 and the intensity of the reflected light from the magnetic head 2 is measured by the optical pickup 3.

Title: Image forming device

IPC: G03G15/00
Filed: 1990-02-19
Abstract: PURPOSE:To prevent the temperature of a heating element provided near a guiding member from rising and to remove warm air around the heating element by forming an aperture part for air passage from which the heat of the heating element is allowed to escape on the guiding member. CONSTITUTION:When a transfer paper 17 advances from a paper feeding port 3, the outside air lower than the temperature on the surface of the paper 17 is sent in a main body with air flow generated by air resistance on the surface of the paper 17. A part of the air flow becomes air flow 18 and cools a code reel 10 and a solenoid 11, etc. At such a time, air flow 20 which flows through the holes 6b and 6c of a guide 6 from the back side to the surface side is generated. When the paper 17 passes above the holes 6b and 6c, the paper 17 absorbs the heat from the air flowing in the air flow 20 and accumulates it, then the temperature of the paper 17 itself rises to lower the temperature of the air flow 20. The paper 17 passing between the guides 6 and 7 leads in the air flow 20 in its advancing direction, and sends it out before rollers 8 and 9. The air passes between the core bar 8a of the roller 8 and the roller 9 and becomes air flow 21. As a result, the temperatures of the reel 10 and the solenoid 11 are prevented from rising.
