Title: Booster of brake for vehicle
Inventor: WANG SOO LEE
IPC: B60T13/56
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To prevent transmission of noise generated by fast inflow of air to the outside by setting a noise insulating plate to reflect noises in the inside of a valve main body one end of which is fixed on an inner peripheral surface of a diaphragm and on the other end of which an air suction part is provided. SOLUTION: A poppet valve 50 to selectively communicate outside air and a transformer chamber 16 to each other and simultaneously to shut off the transformer chamber 16 and a positive pressure chamber 15 from each other or to shut off the outside air and the transformer chamber 16 from each other and simultaneously to communicate the transformer chamber 16 and the positive pressure chamber 15 to each other is set on a valve main body 20. Though noise is generated at the time when outside air flows in the transformer chamber 16 with actuation of the poppet valve 50, when a disc type noise insulating plate 70 is set between a fixed projection 31 to support a spring 32 of an input shaft 30 and a silencer 27, noise generated in the inside of the valve main body 20 is extinguished before it is discharged outside through an air suction part 21.  Consequently, sucked noise is not transmitted to a driver, and the driver can drive in a comfortable environment.

Title: Nonaquous electrolyte secondary battery
Inventor: KOMATSU SHIGEO
IPC: H01M4/133
Filed: 1992-11-30
Abstract: PURPOSE:To provide a high capacity carbon negative electrode by using highly crystalline carbon material for the negative electrode, and setting a charge quantity of the carbon material in a range of 0.9g/cm<3> or more and 1.6g/cm<3> or less. CONSTITUTION:A secondary battery is provided with a positive electrode capable of repeated charges and discharges, nonaqueous electrolyte including alkali metal ions, and a negative electrode comprising carbon material capable of storage and emission of the alkali metal ions. A spacing (d002) of a surface (002) by an X-ray wide angle diffraction method in the carbon material is set to be less than 0.337nm, and a charging density of the carbon material to the negative electrode is set to be 0.9g/cm<3> or more and 1.6g/cm<3> or less. In the case of the negative electrode which is applied as paste of the carbon material and binder formed by organic solvent, if a surface area of the carbon material is large, with a small grain size, a bulk density of the carbon material is low, so the charging density to the electrode is small if it is rolled. A high capacity can thus be achieved by using this negative electrode.

IPC: B66F11/00
Filed: 1999-12-07
Abstract: PROBLEM TO BE SOLVED: To easily and quickly load and unload tools to be stored on a high plane, such as on a vehicle body. SOLUTION: A load carrying platform 3 allowing a tool such as a chair to be attached thereto and removed and a driveshaft 9 rotated in opposite directions by a drive source 4 are interconnected by a swing arm 11. Oscillation of the swing arm 11 causes the load carrying platform 3 lying on the vehicle body 1 to tilt and fall from the top of the vehicle body 1, with the connection between the platform and the swing arm 11 facing up. A speed governor 3 is attached to the driveshaft 9, and a counter torsional moment resisting the torsional moment produced by the swing arm 11 is produced on the driveshaft 9 according to the inclination of the swing arm 11. Thus, the swing arm 11 oscillates at a constant angular velocity, whereby the tool held on the load carrying platform 3 can be easily and quickly loaded and unloaded without plummeting.
