摘要:
A steering handlebar apparatus for a vehicle includes a rod-shaped steering handlebar having a hand grip at a distal end thereof, and also includes both a clutch lever and a hot start lever mounted thereon at a position proximal to the hand grip. A switch holder for holding various switches is mounted to the steering handlebar at a position proximal to the hand grip. The hot start lever is journaled on the lower surface of the switch holder so that the user can operate the hot start lever with the thumb of the hand which is holding the hand grip, and can simultaneously turn off the clutch lever with other fingers of the same hand. The inventive arrangement provides a steering handlebar apparatus for a vehicle which facilitates simultaneous operation of a handle lever and a hot start lever using the hand which is holding a hand grip of a steering handlebar.

A method for manufacturing a wiring board for mounting an electronic component, a wiring board for mounting an electronic component, and a method for manufacturing an electronic-component-mounted wiring board are provided. A bonding material paste, which can include solder and an electric insulation material made of a resin, can be placed on chip mount terminal pads and heated to fuse the solder and soften the electric insulation material. Subsequently, the solder is solidified to form solder bumps. Further, the electric insulation material is cured on a surface of each of the solder bumps and a surface of a multilayer board around each of the solder bumps to form an electric insulation surface layer. Accordingly, when a chip is mounted to such wiring boards, the electric insulation surface layer minimizes or eliminates the connection between adjacent solder bumps during re-fusing of the solder.

Disclosed is a novel cell mass derived from a cancer tissue, which can reflect the in vivo behavior of a cancer cell correctly. Also disclosed is a process for preparing the cell mass. Specifically disclosed is a cell mass derived from a cancer tissue, which is an separated product that is isolated from a cancer tissue obtained from an individual as a mass containing at least three cancer cells or a cultured product of the separated product and which can retain a proliferation ability in vitro. The cell mass derived from a cancer tissue is produced by, for example, a preparation process comprising the steps of: treating a pulverized product of a cancer tissue removed from a living body with an enzyme; and selecting and collecting a mass containing at least three cancer cells among from an enzymatic treatment product.

Specifically, the present invention provides a virus or a viral vector which comprises a gene encoding a fusion protein of an ODD and a protein essentially required for viral proliferation, and a pharmaceutical composition comprising the same.
摘要:
A mass flow rate of NOx which is recirculated to an intake passage with a blowby gas is obtained with high precision, and based on the result, a state of an internal combustion engine can be accurately diagnosed. A control device for an internal combustion engine of the present invention measures a NOx concentration in an intake passage downstream from a position where the blowby gas is recirculated, and similarly measures an oxygen concentration in the intake passage downstream from the aforesaid position. Further, the control device measures a mass flow rate of fresh air taken into the intake passage. The control device calculates a mass flow rate of the blowby gas recirculated to the intake passage from the oxygen concentration and the mass flow rate of the fresh air. Next, the control device calculates a mass flow rate of all gases in the intake passage from the mass flow rate of the fresh air and the mass flow rate of the blowby gas. Subsequently, the control device calculates the mass flow rate of NOx in the aforesaid intake passage from the mass flow rate of all the gases and the NOx concentration. The present control device diagnoses the state of the internal combustion engine based on the mass flow rate of NOx thus calculated.
