Abstract: A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts that encode transport data; a mapping part that performs such a mapping that encoded data sequentially formed by the encoding parts are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.

Abstract: An electric working machine in one aspect of the present disclosure calculates an estimated heat value based on an electric current value and a parameter. The estimated heat value corresponds to an estimated heat generation amount of a motor. The electric current value corresponds to a magnitude of an electric current delivered from a power source to the motor. The electric work machine varies the parameter based on a load time. The load time corresponds to a time period during which a first load is continuously imposed on the motor. The first load has a specified magnitude or more. The electric work machine performs a protective operation for over temperature protection of the motor based on the estimated heat value having reached a heat threshold.

The controller drives the first switch or the second switch by using a PWM signal generated at the first or second carrier frequency and PWM controls an electric power supply to the first or second motor.

Abstract: An electric work machine in one aspect of the present disclosure includes a motor, a manual switch, and a control circuit. The control circuit switches a preset control either to be enabled or disabled. During the preset control being enabled, the control circuit (i) varies an actual rotational speed of the motor in accordance with an actual moved distance of the manual switch and (ii) increases the actual rotational speed in response to a load being imposed on the motor. During the preset control being disabled, the control circuit varies the actual rotational speed in accordance with the actual moved distance of the manual switch in a manner at least partly distinctive from a variation in the actual rotational speed during the preset control being enabled.

Abstract: An adhesive agent, which contains a light starting agent and is cured by light, is added with fillers in which the difference in refractive indices between the adhesive agent and the fillers is not larger than ±0.02. Even if the adhesive agent is added with functional fillers, this addition method allows the suppression of a lowering in the light penetrability of the adhesive agent. As a result, it becomes possible to suppress the uncuring and shrinkage of the photo-curing type adhesive agent and to perform the bonding of components with high accuracy.

Abstract: A variable venturi type carburetor incorporating a changeover valve which conducts the fuel vapor in the float chamber either into the internal passage leading to the suction pipe of the carburetor or into the external passage leading to the canister. The changeover valve is actuated via a rod projecting into the intake passage by a suction piston which is displaced according to the amount of air drawn into the engine and which abuttingly contacts the rod. With this invention, an electromagnetic valve employed in the conventional carburetor can be obviated and the structure of the carburetor becomes simple and small.
