摘要:
The present invention provides a compound consisting of a moiety and a group chemically bonded to said moiety, wherein said moiety contains a compound having low activity following oral administration or its parent scaffold and said group has the following general formula (1): in which R1 represents a hydrogen atom, etc., R2 represents a C1-C7 halogenoalkyl group, etc., m represents an integer of 2 to 14, and n represents an integer of 2 to 7, or enantiomers of the compound, or hydrates or pharmaceutically acceptable salts of the compound or enantiomers thereof. The above compound is advantageous in pharmaceutical use because the group of general formula (1) allows compounds such as anti-estrogenic ones to show a significantly increased activity following oral administration when attached to the parent scaffolds of the compounds.

Provided is a vehicle upper structure which is capable of increasing, in a simple manner, a section modulus (resistive force) against a bending moment to be imposed on a roof reinforcement by a swinging phenomenon of a gusset occurring when a side impact load input into a center pillar and a roof side rail member is applied to the roof reinforcement from the gusset during a vehicle side impact event, to allow the load to be effectively dispersed to the roof reinforcement. The vehicle upper structure comprises a roof side rail member 4, a roof reinforcement 15 and a gusset 30, wherein an end of the gusset 30 on a side fastened to the roof reinforcement 15 has a shape which inclines with respect to a line L1 oriented in a vehicle front-rear direction, in top plan view.

An active bias circuit having a combined configuration of the Wilson and Widlar current source configurations is provided, which makes it possible to set the output bias voltage at approximately 0V even if a reference voltage applied to generate a reference current does not reach 0V. This circuit comprises cascode-connected first and second transistors, cascode-connected third and fourth transistors, and a diode with a specific forward voltage drop generated by a current flowing through the diode itself. The absolute value of the output bias voltage is decreased by the value of the forward voltage drop of the diode compared with the case where the diode is not provided. The diode is provided between the source/emitter of the third transistor and the drain/collector of the fourth transistor, or between the connection point of the third and fourth transistors and the output terminal, or the gates/bases of the first and third transistors.

An exhaust-gas purification device disposition structure of a vehicle, comprises a fuel tank with a fuel supply port which is disposed so as to be open to an outside of a vehicle compartment, and a urea tank to accommodate urea water solution as deoxidizer to purify exhaust gas. The urea tank is disposed outside the vehicle compartment, and a pouring port of the urea tank is provided inside the vehicle compartment. Accordingly, the urea water solution can be surely prevented from entering into the vehicle compartment even in case of the breakage of the urea tank, and the mistake of supplying the wrong liquid into the wrong supply (pouring) port tank which may be made by confusing the ports can be avoided.
