Title: Automobile braking device
Inventor: ICHINOSE KUNIO
IPC: B60W10/06
Filed: 1985-01-24
Abstract: PURPOSE:To improve braking efficiency of a car with a throttle grip such as a motor cycle and the like by furnishing a butterfly valve, which is usually open and is closed by a braking operation, at the intake pipe between the throttle valve and the engine. CONSTITUTION:When a braking mechanism 20 is operated by a wire 14 to act the brake, by handling a brake lever 12, a butterfly valve 32 which is usually open is driven by a wire 34, at the same time, to close the intake pipe 31. Therefore, the fuel feeding to the engine 9 is cut off or reduced, regardless of the condition of a throttle valve 6. When the handling of the brake lever 12 is released, the butterfly valve 32 returns to the original position and the intake pipe 31 is opened. In such a system, the efficiency of the braking can be improved.

Title: Semiconductor integrated circuit
Inventor: TAKAGAKI SHUNICHI
IPC: H01L21/66
Filed: 1995-01-27
Abstract: PURPOSE: To enable a delay pulse test at a high frequency equivalent to an internal clock by generating a high-frequency clock signal based on an input clock and generating a delay pulse with the same delay width as the period thereof. CONSTITUTION: A PLL circuit 40 converts 33MHz low-frequency clock which is inputted 10 to 100MHz high-frequency clock signal, and supplies it to an additional clock circuit 50. The circuit 50 starts generating a clock (a delay pulse comprising two pulse waves) at the same interval as the high-frequency clock frequency generated internally by the circuit 40. An order circuit block 30 of scan path design successively outputs 12 data every time it receives clocks by inputting 11 data, and forms a shift register on testing. In a delay pulse test mode where a select signal 14 is L, the circuit 50 distributes generated clocks to each latch circuit 31, thus executing the delay pulse test of the block 30 in terms of AC.

Abstract: PURPOSE:To obtain the water-level meter of a pressure container free from errors in measurement due to the change in temperature of water by covering the circumference of a reference water- head pipe having lower piping communicated with a reference water leveler with a cooler and a heat-insulating material. CONSTITUTION:Above and below the water level of the pressure container 1 provided inside a building 10 are provided an upper piping 2 and the lower piping 9 respectively, piercing through a side wall respectively, while the upper piping 2 and the lower piping 9 are communicated with each other by the reference water leveler 3 and the reference water-head pipe 8, and the reference water head, as well as the difference between the water head and a hydrostatic head at the measuring point 7 in the pressure container, is detected by a differential pressure detector 6, whereby the water level is found. In this water-level meter, the upper part of the reference water- head pipe 8 is covered with the cooler 12, while the lower side than the cooler is covered with the heat-insulating material 13, and therefore, even when the temperature of atmosphere inside the building rises, the heat quantity flowing from the refrence water leveler and the atmosphere 11 into the reference water-head pipe 8 is restricted. Accordingly, the rise in temperature of the water inside the reference water-head pipe 8 becomes very small and thereby the change in density can be ignored, which enables accurate measurement of water level.

Abstract: PURPOSE:To lessen a pressure drop without changing the thickness of round- shaped cells by constructing this fuel spacer in such a manner that the cells partly overlap longitudinally in the contact parts of the adjacent cells and have the specified thickness in the longitudinal direction. CONSTITUTION:The fuel spacer of the round-shaped cells is constructed by providing bored parts 3 in a part of the side faces of the cells 1 and inserting a part of the adjacent cells 1 to these parts 3 to overlap the contact parts of the cells 1 in the longitudinal direction.

The cells 1 can be worked simply by providing the notched parts in the four directions of the cells 1 and further the adjacent cells 1 are formed by the same working. The workmanship and reliability are consequently good and an increase of cost is averted. The thickness in the contact parts of the cells 1 is reduced to one sheet and, therefore, the formation of fuel rods to the correspondingly larger size is possible.
