摘要:
A fuel pump includes a case member defining a fuel passage and a discharge-side cover connected to the case member and defining an outlet port. A pump section has an inlet port and is connected to the case member. A motor section is housed in the case member for driving the pump section. A positive electrode terminal and a negative electrode terminal are supported by an insulative terminal support member fixed to the discharge-side cover. Base portions of the positive and negative electrode terminals are covered by insulative portions. The insulative portions are fitted in fitting holes of the discharge-side cover. The discharge-side cover has guide portions on its inner surface. The terminal support member has engagement projections on opposite side walls thereof. The engagement projections are guided by the guide portions to restrict the discharge-side cover from rotating with respect to the terminal support member.

Disclosed is a fullerene film which can be easily formed by a wet process without deteriorating the intrinsic properties of a fullerene by using a fullerene derivative as a raw material. Also disclosed are a fullerene polymer, a method for producing a fullerene film, and a method for producing a fullerene polymer. A fullerene film or a fullerene polymer maintaining the intrinsic properties of the fullerene is obtained by coating a base with a solution of a fullerene derivative which is decomposed at a temperature lower than the thermal decomposition temperature of the fullerene, for example one represented by the formula below, and then heating the thus-obtained coating film at a temperature higher than the thermal decomposition temperature of the fullerene derivative but lower than the thermal decomposition temperature of the fullerene.

摘要:
At the step of preheating the container, in addition to heating of the whole container, a neck portion (1a) of the container may be heated separately. Alternatively on the step of preheating the container, while whole container is heated by a hot air blast which is supplied in the container, neck portion (1a) of the container may be heated separately. Since it is difficult to increase the temperature of the neck portion as compared with other portions, by heating the neck portion separately, the effect of the preheating is performed more effectively. It is desirable that the hot air blast is supplied from the nozzle inserted in the container. For example by the method of spraying hot air blast from the outside of the portions, heating of the neck portions can be performed.
