Abstract: PURPOSE:To reinforce the tip part of a traction protrusion so as to improve tractive force and reduce the sliding frictional resistance of a flat sliding part so as to improve durability by constraining the positional relation between the traction protrusion tip part and the lateral rigid member of a track belt into a specified position. CONSTITUTION:A traction protrusion tip 10a is set within the project area S of a lateral rigid member as well as within the range of 0 deg.-theta/2 deg. against a perpendicular on the peripheral plane of a track belt 6, where theta deg. is the angle of the front end of the track belt 6 to the snow contact face G at the time of the traction protrusion 10 intruding into the snow contact face G at the front end, in the advancing direction, of the track belt 6. The slidable part 5a of the track belt 6 against a suspension rail 5 is formed in such a way that the traction protrusion tip 10a is positioned within the project region of the lateral rigid member 1 on a perpendicular headed for the lateral rigid member 11 from the peripheral plane of the track belt 6. The reaction P is thereby generated in the direction of the lateral rigid member at the time of intruding into the snow contact face, as well as the generation of moment by the reaction P is prevented at the flat sliding part.

IPC: G01N33/20
Filed: 1993-04-01
Abstract: PURPOSE: To measure the concentration of gas in a molten metal quickly and accurately by feeding a calibration carrier gas to an analyzer for one step of measurement cycle, feeding and measuring a gas to be measured to a measuring region with no lag, subjecting the partial pressure thereof to primary approximation, and feeding a mixture gas of nitrogen to the measuring region and substituting for the gas to be measured so that an equilibrium concentration is reached quickly. CONSTITUTION: He gas is fed directly from a carrier gas source 1 to an analyzer 3 and calibrated and also fed to a measuring region including a measuring sonde 4. During calibration of the analyzer 3, the gas flowing through the measuring region is discharged through a multi-way valve 6. Upon finishing the calibration, the multi-way valve 6 is switched and a gas to be measured is sampled from a molten metal 5 by means of the measuring sonde 4. subsequently, H2 and CO are removed through an oxidation column 7 and filters 8, 9 and the remaining gas of N2 is analyzed 3 to obtain a primary approximate value. Since the sampling quantity of mixture gas is limited, nitrogen is fed from a gas source 10 to the sonde 4 in the following step so that an equilibrium concentration is reached quickly thus preventing drift due to the molten metal 5.

IPC: B60K5/12
Filed: 1995-04-21
Abstract: PURPOSE: To lighten abutting members by providing a damping main body receiving input vibration and making the part by weight of the wax component of the rubber abutting members, which damp the impact caused in their contacts, be a specified value or less to the raw material rubber component. CONSTITUTION: Thick rubber abutting members 78 are press-fitted in the external periphery of the square column section 70A of a mounting arm 70, playing a part of damping material for absorbing the impact caused when an external cylinder 12C abuts on them. The wax component of the raw material rubber of the abutting members 78 is 0.2 parts by weight or less to a material rubber component of 100 parts by weight, that is, the quantity of paraffin wax is extremely small. Therefore, since the surface friction is very large, once an abutting member 78 is press-fitted, even if vibration or the like works to it, it never comes out from the square column section 70A Since a boss 75 is inserted into a hole 80, the abutting member 78 is surely fixed, and since there is no metal press-fitting section, the abutting member can be lightened, and the number of part items can be reduced.

Title: Fuel injection valve
Inventor: YODOGAWA KATSUO
IPC: F02M61/20
Filed: 1985-05-08
Abstract: PURPOSE:To eliminate problems encountered in that valve closing pressure gets lower than valve opening pressure by permitting fuel oil pressure to act on a control piston provided on an end of a needle valve spring to adjust the valve closing pressure in a needle valve. CONSTITUTION:Fuel oil passes through fuel oil paths 1a, 14a and acts simultaneously on a control piston 13 and a needle valve 3 to operate them. The needle valve 3 is lifted when the fuel oil pressure reaches valve opening pressure, and fuel is injected from a jet 15. Then, since the pressure receiving area of the piston 13 is small than that of the needle valve 3, the piston 13 cannot move downward against a needle valve spring 6. However, when the fuel oil pressure rises further, the piston 13 compresses the needle valve spring 6 and strokes to set the valve closing pressure. When the discharge stroke of a fuel injection pump is completed and thereby the fuel oil pressure drops and reaches the set valve closing pressure, then a force for pushing up the needle valve 3 gets unable of overcoming the force of the needle valve spring 6 so that the needle valve 3 is seated on a seat 2d to complete the injection of fuel.

Filed: 1994-05-11
Abstract: PURPOSE:To prevent the consumption of a battery due to over activation by activating the battery through a load for activating the battery and regulating the operation of the battery activating load thereby activating the battery as required. CONSTITUTION:If a battery activating load 1 is connected with a zero mercury battery 1 prior to the operation for deciding the battery life and the counting time of a timer 12, started counting upon finishing the driving of the load 10, is within a predetermined time, the battery 1 is not activated but the lifetime is decided. The battery 1 is activated only when the counting time of the timer 12 exceeds the predetermined time. Consequently, the battery 1 is not activated every time when the lifetime is decided but it is activated only when the interval between the photographing operations is long. This arrangement prevents the lifetime of the battery 1 from shortening due to the increase of current consumption caused by the operating time of sequence prolonged at the time of continuous photographing.
