Title: Magnetic levitating conveyer
Inventor: KANDA SHUJI
IPC: B65G54/02
Filed: 1993-01-14
Abstract: PURPOSE:To stably levitate a conveying vehicle made runnable by forming staircase parts in end parts of a plurality of tracks for constituting conveying paths, so as to prevent magnetic levitating force from changing regardless of a temperature change in an installation environment. CONSTITUTION:A conveying path for a conveying vehicle is divided into main conveying paths 1X, 1Y respectively mounted on a different building side. In end parts of the main conveying paths 1X, 1Y, end parts of main conveying frames 2A, 2B and 2C, 2D are placed to be opposed through a predetermined space. In point ends of tracks 3A, 3B fixed to the main conveying frames 2A, 2B, 3-step staircase parts 3AX, 3BX are symmetrically formed in the outside. Similarly in point ends of tracks 3C, 3D fixed to the main conveying frames 2C, 2D, staircase parts 3CY, 3DY are formed in the inside. Consequently, even when a space in the end part is widened by contracting the track due to a temperature difference between summer and winter seasons, the track in each staircase part is displaced in a direction of extending/contracting the track, so that electromagnetic force between electromagnet units can be prevented from decreasing.

Title: Cooking utensil by city gas
Inventor: SASADA KATSUMI
IPC: F23N5/02
Filed: 1990-01-12
Abstract: PURPOSE:To broaden the range in which a cooking utensil by city gas can be used by providing a protection cylinder in a through-hole in the center of a burner that is constituted of a burner cap and a burner body and providing a temperature sensor in the protection cylinder with the top face of the sensor being below the upper end of the protection cylinder. CONSTITUTION:A temperature sensor 14 surrounded by a protection cylinder 12 is arranged in the center of the protection cylinder 12 with the top of the sensor 14 below the upper end of the cylinder 12. The temperature sensor 14 is provided with a temperature sensitive element 15 and a spring body 16 in the inside, and it can move up and down. Here, an object 3 to be heated is not put on a five-legged kettle holder 4 but an operation section is operated to supply fuel to a burner 2 and start combustion to use a cooking utensil by city gas. At this time the temperature sensitive sensor 15 is completely shielded from the temperature of the combustion flame 10 by the protection cylinder 12 so that the sensor 15 does not receive the heat of the heat radiation and heat convection by the combustion flame 10, precluding the case of stopping the fuel supply to the burner 2 by erroneous sensing of heat. With this arrangement it is possible not only to prevent an erroneous action of the temperature sensor but also to broaden the range in which a cooking utensil by city gas can be used.

Title: Energy analyzer and spin rotor
Inventor: TAKAHASHI TERUO
IPC: H01J37/05
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To make convergence adjustable by forming the shape of a magnetic electrode such that a sectional face vertical to a charged particle line includes a hyperbola. SOLUTION: A magnetic electrode 1 is shaped in its section including a hyperbola. A magnetic force line 5 thus produced is a hyperbola shape. When an electric field is applied to a charged particle line 6 by an electrode 8, this electric field deflects only an orbit without causing spin rotation. A spin rotation at an arbitrary angle can be realized at the magnetic electrode 1 and the electrode 8 by applying the electric field and magnetic field to the charged particle line 6 at a proper proportion. When the magnetic field in the arrow direction is applied, the charged particle line 6 performs arc movement with (r) as a radium by Lorenz force.  However, because of distributions of a hyperbola-shaped magnetic force line 5, since the rdirection component of the magnetic field is produced at some places, the Lorenz force in (z) direction is produced in the charged particle line 6, and the convergence action in(z) direction is produced. The size of this convergence action can be adjusted by changing the shape of the magnetic electrode or curvature of the magnetic force line 5.

Title: Release film for green sheet
Inventor: INAGAKI MASASHI
IPC: B32B7/06
Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To easily confirm whether a through-hole is regularly punched by regulating transmittivity of the whole ray of light in a polyethylene naphthalate film having a curing silicone resin coating film at least on one side to the value not exceeding a specific rate. SOLUTION: The transmittivity of the whole ray of light in a polyethylene naphthalate film having a curing silicone resin coating film at least on one side is regulated to <=60%. Therein, when the transmittivity of the whole ray of light exceeds 60%, it is confirmed and inspected whether a through-hole is regularly punched after the through-hole is punched. In this confirmation and inspection, when light irradiates a sheet and observation is performed by transmitted light, the difference between quantity of light transmitted from the through-hole and quantity of light transmitted through a release film for a green sheet is difficult to be caused. Therefor, the confirmation and inspection of the through-hole narrowed in the specially thinned green sheet are made difficult. Thereby, it is easily confirmed whether the through-hole is regularly punched.
