In a magnetron for microwave oven, a high-voltage input terminal structure 30 is provided on a shield box 26 mounted on a magnetron unit 22. The high-voltage input terminal structure 30 has a cylindrical earth electrode 33, a cylindrical high potential inner electrode 32 and a central conductor 31a. The cylindrical earth electrode 33 is secured to the shield box 26 and the cylindrical high potential inner electrode 32 is coaxially arranged in the cylindrical earth electrode 33. The central conductor 31a is connected through an inductor 28 to a cathode lead 27 of the magnetron unit 22. An insulating resin 34b is filled in a gap between the cylindrical earth electrode 33 and the highpotential electrode 32 to form a capacitor section C. Cylindrical insulating sheaths 37, 38 are formed by the resin on the both sides of the capacitor section C. The capacitor section C and the cylindrical insulating sheaths, 37, 38 are integrally formed and continuously extended along a straight line.

A mold clamping device for a pressing machine which bends a plate material inserted between upper and lower molds. The mold clamping device comprises a main frame (1) of integral structure, a holding ram (13) mounted on the upper half of the mainframe (1) and for supporting the upper mold (8) for vertical movement, a pair of arch-type thick springs (6) vertically mounted on the upper half of the main frame, and a crank mechanism (10) with which the upper end of each of the arch-type thick spring is connected through a crank pin (17). The crank mechanism creates a rotational force at a position near the dead center of the crank pins (17). This rotational force resiliently deforms the arch-type thick springs (6) which in turn create a resilient force for pressing the upper mold (8) against the lower mold (9). This provides an accurate and stable clamping force between the upper and lower molds.

A data register is provided through a column gate circuit in a ROM array in which font information is stored. Desired font information is read out as parallel data through the column gate circuit based on address information inputted to a row decoder and a column decoder. The data read out is stored once in the data register. Thereafter, the parallel data stored in the data register is outputted to a printing output circuit as serial data in synchronization with reception by a printing output circuit, thereby to perform printing processing. Consequently, font information to be printed need not be stored in a RAM or the like through a data bus, so that processing is simplified and the speed of a processing operation is increased.

In order to economically remove harmful components in exhaust gases by using a simple and extremely durable system, an exhaust gas to be treated is introduced into a neutralizing tower provided with a first duct and a second duct. Harmful components in the exhaust gas chemically react with a neutralizing agent randomly stacked within the neutralizing tower, and such components become deposited on the surface of the neutralizing agent. Water is supplied from a water supply pipe to the surface of the neutralizing agent by driving a pump after passage of a predetermined period of time, and the surface of the neutralizing agent is washed thereby. Additional exhaust gases are further fed and reacted with the neutralizing agent, which has a renewed surface exposed again. The neutralizing agent can thus be repeatedly used for removal of harmful components in the exhaust gases.

An electronic thermometer apparatus includes an indoor temperature sensor, an outdoor temperature sensor, a single display unit capable of displaying exchangeably and alternately the indoor and the outdoor temperatures, means for automatically displaying alternately the indoor and outdoor temperature in a normal mode, means responding to the closing of a change-over switch in the course of the alternate display to thereby display the temperature other than that displayed immediately before the closing of said switch continuously until the switch is again opened, and means for allowing the alternate display of the indoor and outdoor temperatures to be effected automatically in response to the opening of the change-over switch.

A discharge resistor adapted to be mounted on a rotatable shaft of a dynamo-electric device comprises a pair of spirally wound, insulated resistor elements and means for supporting these elements approximately coaxially with the shaft. Each of the resistor elements is spirally wound in a flatwise manner with a bore having an effective diameter greater than that of the shaft, and insulation layers are provided between adjacent turns thereof. The resistor elements are arranged and connected electrically in series such that the inductive impedance appearing across the respective resistor elements effectively cancel each other.

A radome not having a sandwich structure but having a canape structure is formed with an object to obtain a radome of a canape structure having a satisfactory radio property, and moreover, an excellent mechanical strength by providing a matching layer to a skin layer on an interior side of a radome. The skin layer is formed of layered glass fiber cloths and resin impregnated therein. The layered glass fiber cloths can be replaced with glass fiber mats. For the matching layer, a foamed material, such as a urethane material having a low permittivity, or a core material having a resin impregnating property can be used. A radome of a canape structure can be obtained with the skin layer and the matching layer.

A plate bending machine for bending a plate clamped between a lower die and a pressure die by a blade of a bending die mounted on a bend beam which is controlled in the vertical and horizontal directions. The bend beam has a vertical cross-section of substantially C-shaped configuration, and includes a first bending die attached to an upper portion of the substantially C-shaped configuration and a second bending die attached to a lower portion of the same. Blades are formed on at least one of the first and second bending dies to extend in the upward and downward directions, respectively. The horizontal bend arm may be connected to one end of a vertical bend arm which is disposed substantially vertically, by a shaft B (eccentric shaft).
