In a fusion splicing method and device for optical fibers, bare fibers (f) of ribbon optical fibers “F” to be spliced together are arranged, in opposite direction to each other, on a fiber setup stage (30). An interval of a pair of the discharge electrode rods (10,20) is optionally changed according to the fiber number of the bare fibers “f” of the ribbon optical fiber “F” so that all of the bare fibers “f” are set into a uniform temperature area in a discharge area, and an optimum fusion splicing process is performed according to the fiber number of the bare fibers “f”.

In a cup-type beverage vending machine, during conveyance of a beverage-filled cup to a product taking-out position and when the cup does not reach the product taking-out position, a pivot arm is supported by a support roller and a cup on a cup stage is held by a holder. When the cup reaches the product taking-out position, a lower edge of the pivot arm is released from the support roller and the pivot arm and the holder are pivoted downward. Consequently, the holder is spaced downward apart from a front surface of the cup, which allows a customer to easily take out the cup.

The present invention relates to a thermosetting low dielectric resin composition, a laminate for use in printed wiring, a laminate for a circuit, and the like. The present invention's thermosetting low dielectric resin composition contains a specific siloxane denatured polyimide, a compound having two or more allyl or methylallyl groups, and a compound having two or more maleimide groups. This resin composition adheres extremely well to metals with a low dielectric constant and low dielectric dissipation factor, and demonstrates very little scattering of the resin during operational processes like punching or cutting. By using laminates or laminates for circuits that employ this resin composition, electrical signals can be propagated more quickly, enabling signals to be processed at faster speeds. In addition, the present invention can be applied to the formation of miniaturized circuit wiring, and is suitably employed in electronic devices employed in the high frequency region, and, in particular, in electronic devices that must be made smaller and lighter in weight.

A premold type semiconductor package includes a plurality of leads arranged side by side and having upper and lower common surfaces, a mold resin integrally molded with the leads for securing them from the upper and lower surfaces thereof. The mold resin defines a chip mounting recess at an upper side on the first surfaces of the leads, so that a semiconductor chip is to be mounted in the recess. The upper surfaces of the leads are partially exposed in the recess so as to define internal connecting terminals to which the semiconductor chip is to be electrically connected. The mold resin is provided with a plurality of holes by which the lower surfaces of the leads are partially exposed to define external connecting terminals.

A focus control apparatus for a multilayer optical recording medium performs an adequate focus jump on a multilayer optical recording medium. Threshold values are set according to the amount of a level change in a focus error signal of a loaded multilayer optical recording medium, and focus jump control is conducted based on the result of comparison between the level of the focus error signal and the set threshold values. Positive and negative threshold values to be compared with the level of the focus error signal to detect a zero-crossing point of the focus error signal are set in accordance with the amount of a level change in the focus error signal, after which an acceleration operation of the focus actuator is started in response to a focus jump instruction to shift the focus position of read light for a focus jump, the acceleration operation is stopped in accordance with zero-crossing detection, a deceleration operation of the focus actuator is started thereafter and is stopped in accordance with zero-crossing detection, so that the operation returns to the focus servo operation.

A diesel engine has a fuel injection nozzle to which pressurized fuel is supplied from a pump. The nozzle has a pressure sensor detecting the fuel pressure and a lift sensor sensing a lift magnitude of a needle valve. An electronic control unit (ECU) computes a variation ratio of the fuel pressure value which is measured by the pressure sensor. The ECU computes a non-increasing point in an increasing part of variation ratio and judge the point to be a timing for starting the fuel injection of the nozzle. The EPU also computes the actual fuel injection amount in accordance with the fuel injection timing as well as the fuel pressure and the lift amount of the needle valve both at the various points. The EPU control the actual injection amount to be identical to a target fuel injection amount.
