Abstract: A lever-fitting-type connector includes a housing having a first terminal and a lever having a second terminal. The housing has a locking projection. The locking projection includes a front inclination surface and a rear inclination surface respectively extending along a sliding direction of the lever, and a ridgeline part where the front and rear inclination surfaces are connected to each other. The lever includes a locked part. The locked part has a convex surface. The convex surface, when the lever slides, moves over the ridgeline part from the front inclination surface toward the rear inclination surface.

Abstract: A lensholder has one focus coil and two tracking coil. The lensholder has an accommodation recess portion accommodating an objective lens. A layer having thermal conductivity is provided between an inner peripheral surface of the lensholder and an outer circumferential surface of the objective lens and between a bottom wall of the lensholder and a one-side lens surface. The objective lens is bonded by an adhesive and is thereby mounted in a state where the layer is interposed individually between the inner peripheral surface of the lensholder and the outer circumferential surface of the objective lens and between the bottom wall of the lensholder and the one-side lens surface.

Abstract: A mowing machine has a machine frame, front and rear wheels rotatably mounted on the machine frame, a control handle mounted on the machine frame, and a cutting assembly suspended by the machine frame for angular movement about a swing axis extending along a direction in which the mowing machine can travel straight. The front and rear wheels comprise single wheels, respectively, so that the mowing machine is two-wheeled. The machine frame, the front and rear wheels, and the control handle jointly serve as a non-swingable section, and the cutting assembly serves as a swingable section, the swingable section being suspended in offset relationship to the swing axis, the swingable section including a guide member for keeping the cutting assembly spaced from ground. The mowing machine may further include an angular range limiting mechanism for limiting the range of angular movement of the swingable section.

Abstract: A micro program control system for use in a data processing system includes a subsidiary control memory for storing the first micro instructions of respective micro programs, and a control memory for storing the second and the remaining micro instructions of the respective micro programs. The subsidinary control memory is coupled to a main memory in which macro instructions of a program for the data processing system are stored. The operation code of the macro instruction includes a code to address the first micro instruction in the subsidiary control memory, so that one of the first micro instructions can be accessed to supply into a control register when the macro instruction is read out from the main memory to an instruction register of the data processing system, whereby control signals for controlling the operation of the data processing system are delivered from the control register according to the contents of the first micro instruction.
