Chain tensioner

A chain tensioner includes a housing having a cylinder chamber. A plunger is slidably mounted in the cylinder chamber. A spring is mounted in the cylinder chamber to bias the plunger outwardly of the cylinder chamber. The plunger has a radially extending locking pin at its lower portion near its front end. The housing is formed with a pin hole extending substantially perpendicular to an axis of the cylinder chamber near the front end of the housing and under the cylinder chamber. The chain tensioner further includes a support pin inserted in the pin hole, and a locking lever supported on the support pin so as to be pivotable about the support pin. The locking lever can engage the locking pin when the plunger is sufficiently pushed into the cylinder chamber, thereby keeping the plunger pushed in the cylinder chamber.

Coolant for air-bag gas generator and production method therefor

The present invention provides a coolant for an air bag inflator in which unevenness in density in the axial direction is reduced even though the coolant is compressed in its axial direction.The coolant is a molded product made of wire rods and compressed in its axial direction. An absolute value of a difference between a radial pressure loss of the axially upper half portion of the coolant and a radial pressure loss of the axially lower half portion of the coolant is 10 mm H2O or less at a flow rate of 250 liters / minute under the atmosphere of 20° C.

Lithographic mask, and method for covering a mask layer

A lithographic mask having a mask substrate (3) and a patterned mask layer (4) which includes mask structures (5) and can be transferred by lithography to a further substrate is disclosed. With masks of this type, it is customary for a protective layer to be provided in the form of a membrane positioned at a distance from the mask layer (4), in order to keep impurity particles or other impurities away from the focal plane of the mask layer (4). According to the invention, the protective layer (6) is applied in liquid form directly to the mask structures (5) and fills up spaces between the mask structures (4). Then, the protective layer (6), while it is still in the liquid state, is covered with a plane-parallel plate. The continuously dense protective layer (6) which is formed in accordance with the invention is even more reliable in preventing impurity particles or impurities (20) from penetrating into spacers between the structures (5) of the mask layer (4). The impurity particles or impurities (20) can only be deposited on the outer side (16) of the protective layer (6), at a still greater distance from the focal plane.

Discharge lamp lighting circuit

A control section is used to control a DC-to-AC converter circuit to perform lighting control of a discharge lamp. A transformer, switching elements, and a capacitor for resonance are included. The switching elements are driven and serial resonance of the capacitor and the inductance component of the transformer or an inductance element is produced. Before the discharge lamp is turned on, control is performed to cause the driving frequency of the switching elements to gradually approach Foff and to supply a start signal to the discharge lamp. Once the discharge lamp is turned on, control is performed to continuously change the driving frequency from f1 assumed before the discharge lamp is turned on to f2. A residence time in a frequency range lower than Fon is secured then the frequency is shifted to a frequency range fb higher than Fon, or an inductive range fb.
