摘要:
Leakage of silicon melt is monitored and touch of a seed crystal at the silicon melt is detected, and in addition, reinforcement of a vitreous silica crucible to be endurable during pulling for a long time and decrease of impurity concentration of a silicon single crystal can be expected. A method for manufacturing a silicon single crystal is provided. The method includes: detecting touching status of a seed crystal at silicon melt by supplying voltage V1 using a crucible side as a negative electrode and a wire side as a positive electrode and by monitoring change of the voltage, when the seed crystal provided at a front end of the wire touches the silicon melt inside a vitreous silica crucible; devitrifying an inner surface of the vitreous silica crucible as supplying voltage V2 using the crucible side as a positive electrode and the wire side as a negative electrode during a temperature control period; and growing a silicon single crystal by slowly pulling the seed crystal as supplying voltage V3 using the crucible side as a negative electrode and the wire side as a positive electrode after the temperature control period.

Provided is a prize acquisition game device in which a control unit constituted from a microcomputer controls a prize acquisition unit that moves in a game space with a plurality of prizes disposed therein, and controls the acquisition of the prize. The control device moves the prize acquisition unit to the target prize based on an operation signal, judges the success of the acquisition of the prize, and moves the prize acquisition unit that acquired the prize to apposition where the prize can be paid out to the player. And an obstruction unit for obstructing the prize while it is being transported, or when the prize is to be dropped in the prize payout slot has been provided.
摘要:
On a circuit board of the high-frequency module, an RF circuit and an antenna element are arranged, and transmission lines between both the RF circuit and the antenna element are provided. The transmission line of the RF circuit side among the transmission lines is led-out from the top of the circuit board to a rear surface side of the circuit board through a via hole, and the transmission line of the antenna element side is led-out from the top of the circuit board to the rear surface side through another via hole. Electrical continuity between tip portions of the transmission lines is blocked off on the rear surface of the circuit board; however, when the high-frequency module is mounted on the motherboard, a bridging connection land is soldered to each of the tip portions, so that the transmission lines are connected with each other.

According to one embodiment, an electronic device includes a display module, a power button, at least one function button, a hardware controller, and a pre-OS boot processor. The display module displays display data processed by an application on an operating system (OS) or display data based on received broadcast waves. The power button is operated to power on or off the electronic device. The function button is provided separately from a hardware keyboard having a plurality of keys to control a function defined on the OS. The hardware controller is activated in response to power-on operation made on the power button and provide the OS with basic input/output mechanism with respect to hardware including the function button. The pre-OS boot processor performs a process before boot-up of the OS if a predetermined operation is made on the function button within a predetermined time since the power-on operation is made.
