This invention provides a duo-two leading type drum brake device which simplifies a drum brake structure as well as improves a transmission efficiency of a application force from a shoe actuator to brake shoes. A pivot lever 60 has an intermediate portion pivotally supported on the brake shoes 40. A shoe-actuator 20 is positioned adjacent to the first anchors 30, 30 and being disposed between the ends 60a, 50a of the pivot lever 60 and the other brake shoe 50. A strut 70 is positioned between and functionally engaged with the other ends 60b, 50b of the pivot lever 60 and the other brake shoe 50. An application force of the shoe actuator 20 is transmitted to the brake shoe 40 via a pivot section of the pivot lever 70 and transmitted to the other brake shoe 50 directly from the shoe-actuator 20 and indirectly via the strut 70.

It is an object of this invention to provide a drum brake device which solves a problem of decreasing the strength of a back plate near an anchor block and reduces potential damage to the parking brake cable. A pivot lever 60 is pivotally mounted on one brake shoe 20. Upper and lower portions of the pivot lever functionally engage with the other brake shoe 30 via struts 81, 70. A parking brake actuator 90 which pivotally supports on the upper strut 81 and activates upon an activation of a parking brake is arranged to be adjacent to a service brake actuator which activates upon an activation of a service brake. Preferably an operational part of the parking brake actuator is projected out from the brake back plate.

An operation lever unit includes an operation handle attached to an operating rod of an engine-powered portable working machine. The operation handle is equipped with a throttle lever for regulating the power of an engine, a lock lever for holding the throttle lever in a desired position, and a secondary throttle adjustment lever for achieving a fine adjustment of the position of the throttle lever. To hold the throttle lever in the desired position, the throttle lever is forced against a portion of the operation handle by the action of a thrust cam mechanism disposed between the throttle lever and the lock lever. For achieving the fine adjustment of the throttle lever position, the secondary throttle adjustment lever is forced by a thumb of the operator to forcibly turn the throttle lever against a frictional force acting between the throttle lever and the handle portion.

A reference image and an index image are displayed on a three-dimensional display device with either one of the images taken as a left eye image and the other image taken as a right eye image. When a movement command to move a display position of the index image is inputted by a person to be inspected in order that a predetermined reference position of the reference image and the display position of the index image coincide with each other, the display position of the index image is moved on the basis of the movement command. The amount of deviation of the index image from the reference position of the reference image is calculated by the person to be inspected visually recognizing that the reference position of the reference image and the display position of the index image coincide with each other when confirmation input indicating that the person to be inspected visually recognizes the coincidence is provided by the person to be inspected.

Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved. Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line. In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected.

A memory has plural storage areas for storing performance data of plural music pieces. When the player has input desired performance data via an input device like a keyboard, the thus-input performance data are automatically stored into a first storage area of the memory. At the same time, a specific search is executed by the search section to examine whether or not performance data of a music piece corresponding to the input performance data are already stored in the memory. If a second storage area storing the performance data corresponding to the input performance data has been detected or searched out, a series of the performance data stored in the second storage area are sequentially read out for an automatic reproductive performance. If, on the other hand, such a second storage area has not been detected, writing of the input performance data into the first storage area is continued without such an automatic reproductive performance being executed. Therefore, it is sufficient for the player to perform an operation to input a part or whole part of the desired music piece. Then, in response to the player's input operation, music piece number selection and readout or write processes are automatically carried out in accordance with the result of the search by the search section.
摘要:
In order to accomplish the aforementioned and other objects, a resin muffler, according to the invention, is formed of a heat-resistantive synthetic resin having a property of visco-elastic plasticity in a predetermined temperature range. In the visco-elastic temperature range, the motion of the molecular chain segment of the material resin comes to be relaxed to exhibit noise creative pulsating energy dissipation owing to emission as heat energy. Since the resin muffler thus absorbs noise creative energy by dissipation at around the visco-elastic temperature range and transform the energy into the heat energy which may be emitted by radiation.
