46results about How to "Reduce introduction cost" patented technology

The invention provides an optical transmission system which is applicable not only to a known signal but also to an unknown signal, is low in cost, and has high reliability. A branching device branches the optical transmission output of a transmitter, transmits the branched signals over different optical transmission channels. A polarization mode dispersion monitor monitors the state of polarization mode dispersion from the optical transmission channels at the receiving end. A switch control circuit and a switch select a signal with smaller quality deterioration due to the polarization mode dispersion to output it to a receiver (8). This makes it possible to reduce the probability of the quality deterioration of a transmission signal due to polarization mode dispersion.

An analysis method for carrying out an analysis for responses of a computer system including a plurality of servers, includes: obtaining data concerning a CPU utilization ratio of each of the plurality of servers from the computer system, and storing the data concerning the CPU utilization ratio into a CPU utilization ratio storage; obtaining processing history data generated in the computer system, generating data of a request frequency by users of the computer system, and storing the processing history data into a request frequency data storage; and estimating an average delay time in each server by using the CPU utilization ratio of each server, which is stored in the CPU utilization ratio storage, and the request frequency stored in the request frequency data storage, and storing the estimated average delay time into a server delay time storage. By carrying out such a processing, the analysis can be carried out without changing the computer system to be analyzed and any additional cost.

In a mass flow controller verifying system, there are provided a verifying gas line arranged in parallel to influent flow gas lines and joined into a post-confluent flow gas line, a reference volume calculating portion adapted to calculate a reference volume determined for a specified piping of a gas piping system, a verifying parameter calculating portion adapted to calculate a verifying parameter based on time series data of a measurement pressure measured by a pressure measurement unit during a control of a flow rate by a mass flow controller to be verified, and a comparing portion adapted to compare a reference parameter set based on the reference volume and the verifying parameter, whereby the verifying system can be introduced into an existing gas piping system used in a semiconductor manufacturing process and so forth at a low cost and is capable of verifying a mass flow controller quickly and accurately.

To provide a small-size, simply-structured, and low-cost one-pedal type pedal apparatus that is easily mountable to an existing brake pedal without modifying the brake pedal, and that does not extendthe pedal tread toward a driver side, enables a brake and an accelerator to be operated even in a state where the right foot heel is placed on a floor, and permits slight misalignment of a pedal treading position by surely being operated in an accelerator closing direction during braking. This pedal apparatus is provided with: a frame that comprises a bracket mountable to an existing brake pedal,and a base extended rightward from the bracket; an accelerator pad that is mounted so as to be slidable left and right on the base via a slide mechanism provided to the upper surface of the base; anda transmission means for transmitting the position of the accelerator pad to an automobile accelerator device. The pedal apparatus is characterized in that the base is arranged so as to incline downward toward the bracket, the accelerator pad has a shape in which a tread is lower than the tread of the brake pedal in a state where the accelerator pad is set at the leftmost position, a biasing meansfor biasing the accelerator pad leftward is provided, and the base is provided to the bracket at an angle where the right end of the base is closer to the driver side.

A code label printer is provided for producing code labels reliable to use in the market, the label printer checking a code such as a barcode printed on a label which is affixed on a product. In a code label printer 2, print barcode data D1 transmitted from a host computer 3 is received by a microcomputer board 7, a print engine 8 prints a barcode on a label in accordance with the received print barcode data D1, and a label affixing apparatus 9 affixes the barcode-printed label to a product on a conveying apparatus 6. Thereafter, a barcode reader 10 reads out barcode data D2 from the code printed on the label affixed to the product 5 on the conveying apparatus 6, and the readout barcode data D2 and the print barcode data D1 are collated, for attaining a result whether the barcode is correctly read out or not, in the microcomputer board 7.
