Resistors comprising 4 to 20% by weight aluminum phosphate, 72 to 95% by weight tin oxide and 0.8 to 9.6% by weight antimony oxide. Such resistors are produced by adding low melting-point glass to the resistor components so that the latter can be made to stick together and harden into coherent solid bodies.

The ignition system is provided at least two coils for generating voltages with phase different from each other. One of the coils charges a capacitor and the other mainly generates an electric signal for preventing reverse rotation. During the reverse rotation of the engine, said other coil so operates as to let the capacitor charging current flow not to the capacitor but to the ground, thereby preventing ignition sparks.

A voltage-to-current converter serving as a function generator or an essential element thereof and producing various output voltages in accordance with an input signal. It comprises a voltage-to-current converter circuit including at least two transistors, one of these transistors being an output transistor carrying current proportional to the potential difference between two input terminals respectively connected to the emitters of the two transistors, and a current-to-current converter providing at an output terminal a current proportional to the current through the afore-mentioned output transistor. With this voltage-tocurrent converter a function generator of a simple circuit construction may be produced inexpensively. Also, it may be readily made as a semiconductor integrated circuit.

Heat sinks respectively carrying the positive pole pole diodes and negative pole diodes of a three-phase rectifier are assembled with their diodes and with screw studs and the free diode leads are soldered to strips connecting conjugate diodes to which socket contacts are soldered in the middle of the respective strips before the whole assembly is flooded with a resin, pressed and allowed to harden into an integral unit. Leads from the generator windings are soldered into the socket contacts and the rectifier assembly is mounted inside an end-bell of the generator by means of the screw studs of the rectifier unit. In a modified construction a screw stud affixed to the positive heat sink is set in a depression of the heat sink plate and insulated therefrom by a bushing.

A device for controlling the closure of a carburetor butterfly valve, comprising a lever pivotally movable integrally with the carburetor butterfly valve of an engine, a dash pot having a main shaft caused to make a reciprocal movement by said lever incident to the opening and closing operation of said butterfly valve and a sub-shaft operatively associated with said main shaft to make a reciprocal movement and having at one end a change-over valve for changing over the passages of fluid, said dash pot being provided with means for mechanically retarding the movement of said main shaft when said butterfly valve is closed, and a positioner which, when said butterfly valve is opened, is shifted to a position to limit the closure of said butterfly valve under the fluid pressure supplied to said positioner through the operation of said changeover valve, whereby at the time of deceleration of the engine the opening of the said butterfly valve is maintained larger than that at no-load operation of the engine for a predetermined period of time.
摘要:
A rotary electric machine especially suitable for use as a starter for automotive vehicle engines having a yoke, a plurality of pole cores and a plurality of field coils corresponding to the number of poles. The inner and/or outer surface of the yoke and the field coil mounting surface of the pole cores are covered with an electrically insulating coating. The field coils are formed by continuously and directly winding a plurality of electrically insulated magnet wires around the central projecting portion of the pole cores within the space defined between the inner surface of the yoke and the field coil mounting surface of the pole cores, and an electrical insulator is applied to fill the gap between the magnet wires, between the yoke and the field coils, and between the pole cores and the field coils.
摘要:
A secondary air supply system for use with an internal combustion engine includes an air supply system comprising an air pump adapted to be intermittently operated and an air supply conduit extending from the air pump to an air manifold communicated with exhaust ports of respective engine cylinders. First and second check valves are provided in series in the air conduit so as to prevent back flow of the exhaust gas toward the air pump. The first check valve is positioned adjacent the air pump and characterized by its high blocking performance while the second check valve is characterized by its high heat-resistant and corrosion-resistant properties.
