Supporting pieces (42) on side surfaces of a waiting-side connector (20) are insertable into supporting grooves (15) of a casing (10). Contact projections (47F, 47R) are on one outer wall surface (46) of each supporting piece near the upper end and bottom ends. A squeezable projection (55) is on an outer wall surface (44) opposite from the outer wall surface (46) where the contact projections (47) are provided. The squeezable projection (55) has a substantially triangular cross section and contacts a wall surface (13A) of the supporting groove (15) as insertion of the supporting piece (42) into the supporting groove (15) progresses. A tip of the squeezable projection (55) is squeezed at a final stage of the insertion to engage the supporting piece (42) with the supporting groove (15). Accordingly, the waiting-side connector (20) is supported in the casing (10) without shaking.

Fixing members (30) fixable to a circuit board (K) by soldering are mounted in a housing (10). Each fixing member (30) is comprised of a main panel (31) and a solder leg (32) projecting sideways from the bottom end of the main portion (31). The solder leg (32) has solder entering holes (37) that open at a side of the solder leg (32) toward the circuit board K and at a side opposite therefrom. Each solder entering hole (37) has a cross-section that gradually increases toward both upper and lower open ends (37a, 37b). A locking portion (38) is formed on each solder entering hole (37) and bulges more inward than both open ends (37a, 37b). The locking portion (38) locks solder (H) that enters the solder entering hole (37).

A heating resistor type flow-measuring device is capable of adjusting heating temperature of a heating resistor according to the ambient temperature as well as making the initial adjustment. A heating resistor, a thermoresistance, a group of the resistors, and an amplifier constitute a bridge circuit, and leading terminals of the group of resistors are connected to one of input terminals of an amplifier for amplifying an error voltage through MOS transistors. The heating temperature of the heating resistor can be changed by selecting one of the MOS transistors and turning it on.

In an odor measuring apparatus, a plurality of detection outputs with respect to a sample gas is obtained by a plurality of odor sensors having different response characteristics. In an odor fractionation processing section, based on the detection outputs, it is determined which one of a plurality of predetermined odor categories the odor of the sample gas belongs to. In case of calculating an odor index from the detection outputs, the same regression line can be utilized for the same odor category. An odor index calculating section utilizes regression coefficients determined in advance for each odor category, to thereby calculate the odor index. Accordingly, without using an organoleptic test by panels, the odor index can be obtained easily and accurately.

An odor measuring device has a collector tube containing an adsorbent which adsorbs sample components with odor at normal temperatures and desorbs them when heated. Flow routes for a sample gas containing sample components to be detected and an inactive gas are connected through valves to this collector tube. Initially, a sample gas containing sample components with odor is introduced into the collector tube at normal temperature such that the sample components to be detected are adsorbed to the adsorbent. Thereafter, the valves are switched such that the inactive gas is introduced into the collector tube while its temperature is increased by a heater, causing the sample components to be desorbed into the inactive gas and to be transported into an odor sensor. If odor sensors requiring oxygen for detection are used, an oxygen-containing gas such as air is mixed into the inactive gas after the latter has passed through the collector tube such that deterioration of the adsorbent by oxidation can be prevented.

A sheet feeding device avoiding diagonal feeding of a sheet for use in an image forming apparatus. The image forming apparatus includes a sheet cassette and a sheet supply roller unit positioned deviatedly with respect to a widthwise center of the cassette. The deviated position of the sheet supply roller provides rotational force to the sheet for causing diagonal feeding thereof. The sheet feeding device includes a plurality of feed rollers arrayed side by side in the widthwise direction of the sheet. One feed roller positioned close to the sheet supply roller unit provides the sheet feeding force greater than that of the remaining sheet feed roller positioned far away from the sheet supply roller for providing a linear relationship between a resultant sheet feeding force and a resultant resistive force in a direction parallel with the sheet feeding direction. The difference in sheet feeding force is provided by changing nipping pressure of the feed rollers, friction coefficient thereof, or peripheral speed thereof.

An ink filter having a fine mesh structure secured to an ink supply passageway is erected at a side portion of an ink reservoir. An upper portion of the ink reservoir communicates with the atmosphere through an air filter, a lower side portion communicates with the ink supply passageway. An ink filter interrupts the ink supply passageway at an upper portion and has a predetermined height to ensure maintenance of a column of ink in the ink supply passageway. As a result of the capillary phenomenon of the ink filter on the ink, the ink fills the entire portion of the ink supply passageway located below the ink filter so that the liquid surface of the ink is above the communication portion between the ink supply passageway and the ink reservoir but below the position of the ink filter.

A first radiation member 165 includes radiation conductors 166 and 167, an arm 168 and a lower connection piece 169 all integrally formed by blanking. A stub 170 is likewise integrally formed on radiation conductor 166. A second radiation member 171 includes radiation conductors 172 and 173, an arm 174 and a lower connection piece 175 all integrally formed by blanking. A stub 176 is likewise integrally formed on radiation conductor 173. A first loop comprised of radiation conductors 167 and 172, arms 168 and 174 and lower connection pieces 169 and 175 exhibits capacitive impedance at a wavelength for use. The overall length of a second loop comprised of radiation conductors 166 and 173, arms 168 and 174 and lower connection pieces 169 and 175 is set equal to that of the first loop. The second loop, however, exhibits inductive impedance at the wavelength for use by adjustment of the length of stubs 170 and 176. Adjusting stubs 170 and 176 enable control of a phase of a current flowing through the second loop.
