Abstract: The object of the invention is to provide a frequency generator which is composed of an oscillator and a frequency doubler and in which difference in amplitude between differential outputs of the frequency doubler can be equalized at low power consumption without adjustment. To achieve the object, the amplitude of differential outputs of the frequency doubler is detected and the delay time of a variable delay circuit is controlled. Owing to this configuration, in case a frequency of the oscillator varies or in case delay time by the delay circuit used in the frequency doubler varies by process variation and others even if the frequency is fixed, the amplitude of the differential outputs of the frequency doubler can be also equalized in the frequency generator.

Abstract: Disclosed is eyewear that may have a half-jacket frame and a removable dust shield for preventing direct impingement of dust upon a wearer's eye. The eyewear may have a titanium frame and removable lenses free of any attachment structure. The frame may have a lens-retaining ridge with a thin cross section. A nosepad on the frame may carry a shield retainer for releasably affixing a shield to the frame. The nosepad and the half-jacket frame front may be cast together in one piece out of titanium or titanium alloy. An anti-slip nosepad cover may partially cover the nosepad and leave the shield retainer exposed. A removable shield may have a lower lens groove that circumferentially mates with an upper lens groove of an orbital of a half-jacket frame, thereby circumferentially completing the lens groove when the shield is in place. A rigid temple may carry a slip resistor for contacting the wearer's skin. The eyewear may have a vent to reduce fogging of the lenses and the shield may be air-permeable.

Abstract: A product fill system and method uses a mode valve. The mode valve is a shuttle valve that allows the shock tube to communicate with the filler valve during a fill operation corresponding to fill mode of the mode valve. If the filler valve is shut off, any overpressure can pass through the mode valve and be absorbed by the shock tube. The mode valve can be switched into a clean mode in which the shock tube is connected more directly in the circuit between the upstream side of the mode valve and the filler valve. In other words, the shock tube is on a side circuit of the main circuit used for product feeding during the fill operation. However, during the clean operation, the shock tube is in the circuit such that cleaning material travels completely throughout the shock tube. The method of the present invention involves the use of the product fill system so as to accommodate cleaning without disassembly of parts.

Abstract: The present invention provides a power amplifier module featuring that: its output power characteristic smoothly changes as the input control voltage changes; and its control sensitivity is stable over a wide dynamic range. By same means, idling current for gain setting is supplied to a single amplifier element or all of multiple stages of amplifier elements of the power amplifier module. By making this idling current behave so as to exponentially change, relative to input control voltage, the invention enables output power control proportional to the input control voltage.

Abstract: A fastening tool applies parts, in particular plastic parts, to objects. The plastic parts are supplied in the form of a belt in which the plastic parts are linked together by at least one flexible web. The fastening tool transports the belt by a feed mechanism such that one plastic part at a time is delivered to a fastening position.

The translation-rotation converter has an overrunning clutch whose driving gear is kinematically coupled to the fluid drive and whose driven gear is coupled to the transport gear in a rotationally fixed manner.

The three standalone processing apparatuses are a dicing apparatus 2, a molding apparatus 4, and a visual inspection apparatus 3. This not only minimizes the possibility of a stagnant flow of workpieces between steps but also substantially shortens the overall processing time.

Abstract: A nonvolatile memory has an erase table in which a free-space information flag is associated with each physical address of a memory area and an address translation table in which a physical address of a memory area is associated with each logical address. The free-space information flag indicates whether a corresponding memory area is permitted to be erased. A control circuit determines a memory area to which rewrite data is to be written by referring to the free-space information flag, reflects the physical address and the logical address of the memory area to which the data is written into the address translation table, and updates the free-space information flag. The memory area to which rewrite data is to be written is determined by referring to the free-space information flag, and rewriting is not performed in the same memory area.
