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.

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.

A network system implements paging control in which the control apparatus, upon receiving a packet destined for a mobile terminal, transmits a paging notification packet to a paging area of the mobile terminal, so as to obtain location information of the mobile terminal and to determine a transfer destination of a received packet. The control apparatus is configured to transmit the paging notification packet to a plurality of router devices included in the paging area. Each of the plurality of router devices is configured to transmit a received paging notification packet to a plurality of access points by multicasting. Each of the plurality of access points is configured to transmit a received paging notification packet to the mobile terminal through a link connection by multicasting, when it is judged that an IP address in the paging notification packet is a predetermined IP address.

A switch box includes an optical-axis-changeover switch for headlamps, an on/off-changeover switch for the headlamps and a starter switch arranged on the same operation board. A main switch can turn on and off a main electric source of an MUV 1 in cooperation with a portable key. The switch box and the main switch are arranged on the instrument panel. The switch box is partially or fully disposed in a projective area of the steering wheel in a driver's eyesight. The starter switch is made to be of a push-type, whereas the optical-axis-changeover switch and the on/off-changeover switch for the headlamps are made to be of a seesaw-type. A segment display of a meter device includes a unit indication member for switchably indicating kilometer indication and mile indication by displaying only an arbitrary display element of a plurality of display elements arranged adjacently to each other in a horizontal direction.
