  • Patent number: 6525972
    Abstract: A semiconductor memory device (50) having a boosted potential generation circuit is provided. The boosted potential generation circuit may provide charge to a boosted potential node when a word line (11) is to be activated. The boosted potential generation circuit may include a boosting control circuit (5), a boosted potential detection circuit (6), an oscillator circuit (7), and a booster circuit (8). The boosting control circuit (5) may generate a boosting control signal when a command decoder (1) indicates that a word line may be activated. In response to the boosting control signal, the boosted potential detection circuit (6) may enable the oscillator circuit (7) so that booster circuit (8) may transfer charge to the boosted potential node. This may allow the boosted potential node to have adequate charge that may be provided to the word line when activated.

  • Publication number: 20020076517
    Abstract: An organic composite insulator (tube) and method for production thereof giving an external flashover characteristic, enabling a reduction of the cost, and enabling a reduction of the size of the insulator. The outside diameters of the insulator sheath body and watersheds at only the intermediate insulator sheath 3c corresponding to the vicinity of the tip 6a of the top of the inside electrode 6 are made larger than the outside diameters of the body and watersheds of the upper and lower insulator sheaths 3a and 3b. The electric field of the sheath surface in the vicinity of the tip 6a of the top of the inside electrode 6 exhibiting the maximum electric field in the large size insulator is weakened and the maximum electric field part is moved to the top portion of the sheath body and watersheds enlarged in inside diameter.

  • Patent number: 6218804
    Abstract: An engine stopping/starting control unit having improved accelerating performance. A charging limiting device is provided which limits the charge provided to a generator when the vehicle is stopped. The decreased charging allows for better performance when the vehicle accelerates from a stopped states. Also, the vehicle headlight can be dimmed while the vehicle is stopped, which reduces the load on the generator. An acceleration detector detects when the vehicle accelerates during running, and can decrease the generator load in response to the acceleration.

  • Patent number: 5272543
    Abstract: A method of progressively reproducing a natural image successively decodes and displays data which are stored in a memory in at least three stages including display of a retrieval image which is used for giving a general idea of the image, a soft copy image which has a sufficiently high resolution for display and a hard copy image which has a sufficiently high resolution for printing. The data stored in the memory includes at least retrieval image data which is obtained by coding the natural image, soft copy image data which is obtained by coding a difference of the retrieval image and the soft copy image and hard copy image data which is obtained by coding a difference of the soft copy image and the hard copy image.

  • Patent number: 4838113
    Abstract: A throttle mechanism for a vehicle employing a handle grip for steering where the throttle lever is controlled by manual actuation. A shield plate may be provided on the throttle lever to physically block the air flow against the vehicle from flowing directly over the operator's thumb actuating the throttle. Heating elements may be provided to heat a cover on the throttle lever which in turn heats the driver's hand. Heat controlling circuits to effectively reduce the heating input at high temperatures, multiple circuits for both rapid and slow heating and circuitry associated with the vehicle lighting switches may be employed.

  • Patent number: 3945340
    Abstract: A device for striking a bell comprises a hammer head having a head portion composed of hard material and another head portion composed of soft material to obtain both hard and soft sounding bell rings. The hammer head is connected to a rockable striking hammer lever which is driven with a rocking motion by a rotating eccentric cam to cause the hammer head to strike the bell. The center of rocking motion of the striking hammer lever can be shifted both manually and automatically to selectively vary the hardness and softness of the bell ring.
