Abstract: An air conditioning system for a vehicle is provided with a heat pump circulation path through which a refrigerant body is circulated through a compressor. The heat pump circulation path is provided with a condenser unit, an expansion valve, a first evaporator, a heater, and a second evaporator. The heat pump circulation path is also provided with a bypass means which, in heating operation, bypasses a main condenser for constituting the condenser unit and connects the heater and a gas-liquid separation-type refrigerant body containing section. The configuration provides effects which minimize an increase in the number of dedicated parts required only in a heating mode and which, by effectively utilizing the system in a cooling mode, prevents a reduction in the air conditioning performance caused by the shortage of the refrigerant body.

Abstract: An image forming device in which, even if exposure processing and developing processing are carried out simultaneously, offset at a time of scanning-exposure in an exposure section, which is caused by relatively rough conveying in a developing section, can be eliminated. Attention is focused on rigidity of a sheet-shaped recording material. A guide plate of a conveying section is bent such that elastic repulsion is generated, and a predetermined frictional force with respect to a driving roller is generated by the elastic repulsion. Thus, even if the driving roller vibrates due to an external disturbance or non-uniform driving occurs, vibration or the like can be absorbed by movement of the recording material in a thickness direction thereof. Thus, conveying of the recording material is not directly affected, and conveying can be stabilized.

Abstract: An anti-slipping agent for a frozen road surface is provided by crushing a stone having flat-crushability such as black slate into flat-crushed pieces of a required grain size. Furthermore, a method for spreading an anti-slipping agent for a frozen road surface is provided in which the anti-slipping agent for a frozen road surface is heated and then spread onto the frozen road surface. Further an apparatus is provided for spreading an anti-slipping agent for a frozen road surface onto a frozen road surface, which has a hopper, a heater and a spreader.
