Abstract: An injection mold and an injection molding apparatus having a movable mold and a fixed mold. Each of the movable/fixed molds has bases, and a runner, a gate and a cavity are formed. The gate is composed of recesses made in mutually opposite end surfaces of sleeve-like heat insulators provided for the bases. Thereby, the gate is heat-insulated, and resin in the gate is prevented from cooling down during a pressure retention step. Thus, the resin keeps fluidity longer.

Abstract: An injection mold composed of a movable mold and a fixed mold. The movable mold has bases, a heat insulating layer and a surface processed layer, and the fixed mold has a base. A heat insulator is provided on the inner circumferential surface of the base of the movable mold at a part forming a wall of a cavity. The heat insulating layer is in the rear of the surface processed layer, and therefore, the transfer accuracy of a fine configuration of the surface processed layer is improved. Additionally, since the heat insulator is provided adjacent to the fine configuration, heat radiation from resin is inhibited, and the transfer accuracy of the fine configuration is further improved.

Abstract: In a complex electronic device, in which device units are arranged so as to have substantially the same height of medium loading spaces, in connecting a circuit board for operation button control and each operation unit by use of FFCs, wiring in a limited space is possible even when the FFCs are bent or folded, without exerting an adverse effect on the arrangement of other parts.

Abstract: An object of the invention is to provide a power supply controller for stopping an output of a power supply portion without adding a new circuit in the combined electronic equipment, and dispensing with ON/OFF operation of a power supply each time for every electronic equipment. The supply of power is controlled by supplying a control signal from a body CPU to voltage conversion circuits for supplying voltages having different levels to corresponding functional blocks, and the voltage conversion circuit for supplying a voltage having a level corresponding to a non-used functional block is controlled to be turned OFF, thereby reducing power consumption.

Abstract: A batch-operated furnace apparatus for manufacturing powdered silicon nitride comprises a reaction furnace having a reaction chamber, an upper portion, a bottom portion and a side portion, a feed pipe placed at the upper portion of the reaction furnace for feeding starting materials in a fine or coarse particle form, an exhaust pipe placed at the upper portion of the reaction furnace for removing gasses from the reaction chamber, a gas distributor plate positioned at the bottom portion of the reaction chamber for introducing nitrogen gas into the reaction chamber so as to form a fluidized bed at the bottom portion of the reaction chamber, a heater for heating the starting materials of the fluidized bed within the reaction chamber, a discharge port formed in the gas distributor plate, a discharge pipe joined to the discharge port of the gas distributor plate, a valve seat formed at the discharge port, a discharge valve means having the valve which engages the valve seat of the discharge port, and a guide tube
