Title: Loudspeaker device
Inventor: WELSH CHRISTOPHER T
IPC: G06F1/16
Filed: 1996-10-22
Abstract: PROBLEM TO BE SOLVED: To provide the speaker system able to be mounted to a lap-top personal computer PC and having a sufficient acoustic space volume. SOLUTION: The speaker system has a surrounding body 10 of a shape easily fitted to the rear side of a display device of a lap-top personal computer PC and provides a sound with high quality. Concretely, the high quality sound and the ease of mount are realized by adopting the surrounding body 101 for a speaker 100 having 1st and 2nd legs and combining the legs to form an L shape. The speaker surrounding body 101 of the speaker 100 is fitted to a rear side of the display device of the lap-top PC by using one leg of the L-shaped surrounding body 101 and the size of the other leg fitted to the PC and viewed by the user is minimized. Since most part of the speaker surrounding body is hidden from the sight of the user of the lap-top PC, the external appearance is excellent.

Title: Electrode position detector for welding
Inventor: SUZUKI KENKICHI
IPC: B23K9/12
Filed: 1986-11-22
Abstract: PURPOSE:To prevent damage of an electrode and to accurately detect the contact position of the electrode with base metal by providing a shock absorber between a mobile member of a slide mechanism and a welding torch supporting member and detecting an operation starting point or a point separated by a prescribed distance from the starting point of the shock absorber. CONSTITUTION:When a driving motor 17 of the slide mechanism 2 is rotated and a movable carriage 3 is lowered, the movable carriage 3 is lowered in a state with the top of a recessed part 14 of a slide base 13 abutted on the top of a feed nut (the mobile member) by its own weight, the weight of the welding torch 5 and the force of a lower side spring 20. When the electrode 4 comes into contact with the base metal, the lowering of the electrode 4, the torch 5 and the movable carriage 3 (the slide base 13) are stopped and only the feed nut 6 is lowered by the rotation of a feed screw 10. At this time, when the feed nut 6 is lowered against the elastic force of the lower side spring 20 and separated from the top of the recessed part 14 of the slide base 13, a contact 24 of the feed nut 6 is separated from a first limit switch 25 arranged to the slide base 13 and this is turned off and the rotating speed of the motor 17 for driving is reduced.

Title: Cathode-ray tube
Inventor: KUSUDA MASAAKI
IPC: H01J29/56
Filed: 1986-11-23
Abstract: PURPOSE:To decrease a difference in dimension of an electrode beam spot in a horizontal scanning direction on a fluorescent screen by scanning electron beams irradiated from an electron gun in a cathode ray tube vertically and horizontally against the fluorescent screen to form an image on the fluorescent screen. CONSTITUTION:In a tube body 17 including a screen panel on the inside of which a fluorescent screen is formed and a neck 15 having a built-in electron gun 30, the fluorescent screen is scanned with electron beams. When an image is formed on the fluorescent screen, the dimension change of electron beam spot over a range from the center to the periphery in a horizontal scanning direction in the fluorescent screen is decreased. Therefore, a drop in resolution and color purity of an image on the fluorescent screen over a range from the center to the periphery in a horizontal scanning direction on the fluorescent screen is also decreased. A deterioration in image quality is decreased in the periphery in a horizontal scanning direction of the fluorescent screen.

Title: Separation of incondensible gas in heat exchanger
Inventor: KOTAKA IKUO
IPC: F28D15/02
Filed: 1986-11-26
Abstract: PURPOSE:To raise heat transfer efficiency by providing a pipe passage which connects the upper header of a group of evaporation pipes and a second condensation pipe in a low temperature gas duct and separating the gas which was not condensated by arranging the direction of the vapor flow of a working medium and the direction of the flow of a condensation liquid mutually oppositely. CONSTITUTION:The water in a group 1 of evaporation pipes becomes steam by a high temperature gas and condenses in a group 3 of condensation pipes in a low temperature duct 4 via an upper header 1, pipe passage 5, and upper header 3b and discharges the condensation latent heat to the low temperature gas and returns to the group 1 of evaporation pipes via a lower header 3a, pipe passage 6, and lower header 1a. On the other hand, part of the steam condenses while it rises in a heat pipe 12 which is a second condensation pipe via a pipe passage 10, and lower header 12a, and the condensing water falls by gravity and enters the pipe passage 6 and incondensible gases are effectively separated from the steam flow by the rising air flow and the downward flow of the water mutually in opposite directions and collect in the upper header 12b, and they are discharged through a gas storage 17 by opening and closing of valves 16a and 16b. It is, therefore, possible to separate and discharge incondensible gases effectively and improve thereby efficiency in heat transfer.

Abstract: PURPOSE:To prevent sliding of an axis and generation of astigmatism by specifying the relationship between an inner radius of an end face of an outer cylinder of a single-pole magnetic lens and the distance between the top of an inner cylinder thereof and a magnetic shield member facing the top of the inner cylinder in the direction of the optical axis and providing a magnetic gap between the end face of the outer cylinder of the single-pole magnetic lens and the magnetic shield member. CONSTITUTION:An objective lens is composed of a single-pole magnetic lens 5. A magnetic shield member 16 is provided at the periphery of a sample 13. The relationship L>R is established where R is an inner radius of an end face of an outer cylinder 9 of a single-pole magnetic lens 5 and L is the distance between the top of an inner cylinder of the single-pole magnetic lens 5 and the magnetic shield member 16 facing the top of the inner cylinder in an optical axis direction. A magnetic space is provided between the outer cylinder 9 of the single-pole magnetic lens 5 and the magnetic shield member 16. Accordingly, the magnetic shield member 16 does not form a magnetic circuit of the single-pole magnetic lens 5, but functions as a shield member of disturbing magnetic field. Therefore, magnetic field of the single-pole magnetic lens 5 is not disturbed and degradation of the axis and astigmatism are prevented.

IPC: G06F17/50
Filed: 1993-10-13
Abstract: PURPOSE:To improve the accuracy of data retrieval from simulated results at a certain time and to suppress increment in the storage capacity of a time table by a time mapping method. CONSTITUTION:A circulation type time table 13 is prepared by a time step DELTAt having comparatively wide width as in a conventional manner and delay time data 22 are included in a construction 20 belonging to an event list 30-i for respective time steps. Simulation time can be highly accurately calculated by adding corresponding delay time data 22 in each tracing of one construction 20 from the start time Ti of each time step. Storage capacity for storing all constructions 20 is not increased/decreased in the same logical circuit. Although the storage capacity of the time table 13 is increased in order to improve its accuracy, the increment of storage capacity can be prevented by this logical circuit simulation method.
