Helicobacter pylori strains are indigenous to each human host and infect and colonize in the stomach of the host, and they are also known to be involved in diseases of the upper gastrointestinal tracts, among others. The present invention provides an economical method for inhibiting the proliferation and migration of Helicobacter pylori strains without being concerned about emergence of resistant bacteria or side effects due to drugs traditionally used to remove Helicobacter pylori strains, as well as a beverage or food utilizing such method, by selecting from among mineral-rich waters obtained from deep sea water, and by ingesting, a water or waters capable of inhibiting the proliferation and migration of Helicobacter pylori strains that are indigenous to the host and infecting and colonized in the stomach of the host.

A stator support device for a torque converter having a stator wheel and a non-rotating member has a one-way clutch and a bearing race. The one-way clutch includes an outer race disposed along the inner periphery of the stator wheel, an inner race connected to the outer periphery of the non-rotating member to prevent rotation of the inner race relative to the non-rotating member, and an end bearing provided between the outer race and the inner race. The bearing race is disposed at a side face of the outer race. The bearing race is supported so as to be rotatable in the circumferential direction. A gap is formed between the bearing race and the stator wheel.

A color image forming apparatus includes an image forming unit which forms a multicolor image on a second image support by sequentially transferring toner images related to a plurality of colors from a first image support to the second image support in an overlaying manner. A reference position detecting unit detects a reference mark signal every time a reference mark at a reference position on the second image support is sensed during rotation of the second image support. A laser scan start timing control unit controls a laser scan start timing for the image forming unit to start scanning the first image support by a laser beam, based on the reference mark signal. A phase error measurement unit measures a phase error between a line sync signal and the reference mark signal by counting system clocks before the laser scan start timing. A drive speed control unit adjusts a rotating speed of the second image support to a controlled speed by outputting a drive pulse to a motor which rotates the second image support, the drive speed control unit determining an ON-state period of the drive pulse depending on the phase error measurement such that a timing of detection of the reference mark signal matches the laser scan start timing.

The invention is directed to a braking pressure control apparatus for controlling a wheel slip of a driven wheel during braking and driving operations, wherein pressure control valves are disposed in the fluid passage between a master cylinder and a wheel brake cylinder, and a changeover valve is disposed in the passage between the master cylinder and the pressure control valves, for blocking the flow of the brake fluid when the wheel slip of the driven wheel is controlled during the driving operation. A first reservoir having a first variable volume chamber for storing the brake fluid discharged from the wheel brake cylinder is provided and normally urged to be of its minimum volume. Also, a second reservoir having a second variable volume chamber for storing the brake fluid discharged from the wheel brake cylinder is provided and normally urged to expand for storing a predetermined amount of the brake fluid. A fluid pump is provided for pumping the brake fluid from the first and second reservoirs, and supplying the pumped brake fluid to the passage between the pressure control valves and the changeover valve in the wheel slip control during the braking and driving operations. Thus, the apparatus may be easily installed in a conventional braking system without any change to the master cylinder reservoir.

An antiskid apparatus for an automotive vehicle including a cut-off valve having an inlet side to which a master cylinder is connected and an outlet side to which a wheel cylinder is connected for cutting off a supply of pressurized oil from the master cylinder to the wheel cylinder when an antiskid operation is performed, and a pump connected between the cut-off valve and wheel cylinder for supplying pressurized oil to the wheel cylinder when an antiskid operation is performed. The master cylinder and wheel cylinder being brought into slight communication via a microgroove in the spool of the cut-off valve when the spool is at a closed position. Pedal shock at antiskid operation is alleviated.

The present invention relates an antiskid apparatus for an automotive vehicle. The apparatus includes a cut-off valve which is connected between a master cylinder and a wheel cylinder and provides communication therebetween in response to wheel cylinder pressure and cuts off pressurized hydraulic fluid from the master cylinder when an antiskid operation is performed by the control system. A solenoid valve is positioned in a conduit which connects the wheel cylinder to the cut-off valve. The solenoid valve is also connected to a discharge side of a pump which circulates pressurized oil. When the solenoid is in a normal position, the wheel cylinder is connected to the cut-off valve in the discharge side of the pump. When changed over from the normal position, the solenoid valve disconnects the wheel cylinder from the cut-off valve and the discharge side of the pump and connects the wheel cylinder to a reservoir connected to an intake side of the pump.

摘要:
A torque converter includes a pump shell constituting an internal space for retaining ATF and capable of rotating about the rotation axis; a blade engaging with the pump shell; and an extension sleeve pressing the blade against the pump shell. The pump shell has a groove into which a tip portion of the blade is fit formed at its inner peripheral surface. In the state where the tip portion is fit into the groove, the extension sleeve presses the blade to fix the blade to the pump shell. The groove forms an acute angle θ with respect to a meridian of the shell passing through the groove. The groove extends in one direction, has one end opened and the other end closed, and has a width larger on the side of the one end than on the side of the other end. The groove has a portion smallest in width equal to the width of the tip portion.
