Abstract: The present invention includes: a cutting blade; an electric motor (5) that rotationally drives the cutting blade; a clutch that engages and disengages transmission of motive power between the electric motor (5) and the cutting blade; operation means for operating the clutch; and controller (30) for controlling operation of the electric motor (5). By means of the operation means, it is possible to switch between a state in which the clutch is disengaged in which motive power of the electric motor (5) is not transmitted to the cutting blade and a state in which the clutch is engaged and motive power of the electric motor (5) is transmitted to the cutting blade.

Abstract: The present disclosure includes: a cutting blade; an electric motor (5) that rotationally drives the cutting blade; a main power source (6) that supplies electric power to the electric motor (5); a clutch that engages and disengages motive power between the electric motor (5) and the cutting blade; an inclination sensor (31) that detects an inclination of the machine body; and a controller (30) for controlling power on and off of the main power source (6). When a direction orthogonal to a travelling direction of the machine body is defined as the horizontal direction, and a center line in a vertical direction of the machine body when the machine body on a horizontal plane is viewed from a front side is defined as a reference line, the controller (30) turns off the main power source when the reference line is inclined at a prescribed angle or more with respect to the horizontal direction or when rotation of the electric motor (5) is stopped for a prescribed time period or more.

Abstract: A new printed board assembly equipped with a male connector is provided. The male connector simplifies a connecting structure at a printed board side while maintaining stability in connection between an external electrical cable and an electrical conductive path on a printed board by being attached to an end of the external electrical cable. A housing contains a male terminal connected to an end of an external electrical cable. While the housing is held on a printed board by a lock means, a biasing means applies a biasing force to the male terminal, so that the male terminal is pressed onto and connected to an electrical conductive path on the printed board.

Abstract: An ice-making unit is so configured as to facilitate cleaning of the backsides of ice-making plates. An evaporator of the ice-making unit is disposed between the backsides of a pair of ice-making plates and has straight portions extending laterally and curved portions sticking out sideward of the ice-making plates, the straight portions and the curved portions being repetitively zigzagged. The curved portion is bent frontward or rearward of the ice-making plates more than a clearance between the ice-making plates. Accordingly, the curved portion is retracted from a side opening defined between the ice-making plates and facing inside the ice-making unit, and does not interfere with cleaning of the backsides of the ice-making plates.

Abstract: A cooling unit adapted for use in a freezing mechanism, which is composed a metallic cylindrical evaporator housing and a metallic freezing pipe helically wound on an outer periphery of the evaporator housing for thermal contact with the evaporator housing, wherein the freezing pipe is embedded in a metal layer formed by slip casting of a low melting point alloy such as aluminum alloy, tin alloy or magnesium alloy on the outer periphery of the evaporator housing.

Abstract: An electronic unit mounted in a vehicle includes a controller unit. The electronic unit is tested by a test device using periodic communications cycled therebetween. A frame of order signal is formulated by loading data designating several ports and transmitted from the test device to the controller unit. The controller unit processes the order signal and returns the processed results to the test device. At least part of the above data are shortened from 8 bits to 4 bits, and several ports are tested in one cycle of the periodic communications. The testing time is thus reduced for the electronic unit.

Abstract: A cooling unit adapted for use in an auger type ice making machine, a freezing mechanism of an ice cream making machine or the like, composed of a metallic cylindrical evaporator housing and a metallic freezing pipe helically wound around the evaporator housing through a metallic filler for thermal contact with the evaporator housing, the metallic filler being embedded in a space between the evaporator housing and the freezing pipe, wherein the entirety of the freezing pipe is covered with a metallic surface layer membrane formed thereon.

Abstract: An inspection program having custom-designed inspection procedures set is stored for each control unit in an inspection program storage section on the control unit. The inspection program is transferred, by means of communications means, to a rewritable inspection program storage section provided in an inspection apparatus. The type of a control unit which is an object of inspection is identified by means of causing the inspection apparatus to run the inspection program. Appropriate input and loads are provided for the control unit, thus causing the control unit to perform inspection procedures.

Abstract: A method for writing data into a non-volatile memory employed in an on-vehicle electronic unit, in that while presently available input circuits 11 to 16 are directly utilized without newly setting an exclusively used interface circuit on the side of an electronic unit 3, such data which is desired to be written into the non-volatile memory 6 is entered into the electronic unit 3. A confirmation is made as to whether or not the data writing operation is carried out under normal condition based upon an output signal derived from a presently available output circuit 18.

Abstract: In a casing for an electronic unit on which connector terminals are integrally provided, to enable observing from the outside to check the solder finish state of the connector terminals soldered to a printed board. At the side surface portion of the casing, there is provided a window, formed as a notch cut open in the underside of the casing, through which the soldered portions 17 where the connector terminals 13 are soldered to the printed board 11 can be visually checked from the outside.

Abstract: A method for testing an on-vehicle electronic unit in that while presently available input circuits 11 to 16 and also output circuits 18 to 22 are directly utilized without newly setting an exclusively used interface circuit on the side of an electronic unit 3, a command instruction is applied to these input circuits and output circuits by way of a multiplex serial communication by turning ON/OFF switches 2a to 2f so as to test as to whether or not the switches 2a to 2f are confirmed under normal states by the respective input circuits 11 to 16. Also, a similar operation signal to the switching operation of the switches 2a to 2f is supplied by way of the command instruction by the multiplex serial communication in order to check as to whether or not the output signals derived from the respective output circuits 18 to 22 are proper.
