IPC: G01N21/76
Filed: 1979-05-22
Abstract: PURPOSE:To achieve analysis of trace component proportional to the level of the luminance quickly with a better sensitivity by introducing luminance from the mixture of the test substance and a reagent in a black box to a photoelectric multiplier through optical fiber and the electric output of the multiplier is counted. CONSTITUTION:The test substance and the reagent which causes luminance when added thereto are put and mixed in a vial 14 outside the black box 10 and simultaneously the switch 34 is turned on. Both the test substance and the reagent starts reaction to produce luminance. The vial is inserted into a container 12 immediately and the first optical shutter 18 is closed while the second shutter 27 is opened. Introduced through optical fiber 24, the luminance in the vial 14 enters a light detecting surface 26a of the photoelectric multiplier 26, which provides the electric output proportional to the level of luminance. As the output is counted by an amplification counting circuit 28 and the counting time is controlled as specified by the timer of a time setting circuit 32, counting is performed only for the specified reaction time after a given time elapses from the start of the luminance. The discrete value of the circuit is digitally indicated on the display for analysis and indication of the trace component in the test substance corresponding to the level of the luminance.

Abstract: PURPOSE:To send out slender magnetic parts to the next process with efficiency by a method wherein slender parts improperly oriented are identified and placed into a separate channel wherein they are given a change of direction of 180 deg. before returning to the means they have been sent out from. CONSTITUTION:A magnetic substance made diode 9 is picked out of a stocker 7 and is placed in a groove located in the outer circumference of a rotory loader 8. The diode 9 is checked at a contact point 10 for its polarity and then passed through a rotor 12 to a next process. A diode 9 reversely oriented polarity- wise is sent to rotors 13-15 through a switching means 11, taken out through a shoot 16, and then returned to the stocker 7 with its orientation 180 deg. changed in a shoot 17. The switching means 11 is provided with a rotating element 19 that nods up and down within an angle of theta causing the send out section 22 to face the upper or lower surface of a guide plate 20. With the send out section 22 facing the upper surface of the plate 20, a diode 9 is sent into a rotor 13 for orientation change. It is not necessary to arrange the slender parts correctly prior to accommodation in the stock 7. All incoming parts are properly handled thereby improving work efficiency.

Title: Very high speed semiconductor device
Inventor: MUTO SHUNICHI
IPC: H01L29/76
Filed: 1987-03-19
Abstract: PURPOSE:To enable a very high speed semiconductor device to operate at room temperature, by utilizing a compound semiconductor having a large energy difference between GAMMA and L valleys for a base layer, while utilizing a compound semiconductor of four or five-element mixed crystals having a large barrier height as a collector-side barrier layer. CONSTITUTION:A very high speed semiconductor device of the present invention includes a base layer of InAs1-xSbx (x >= 0), for example an n-type InAs0.9Sb0.1 base layer 7 and a collector-side barrier layer of a material containing at least InAsGaSb, for example an (InAsSb)0.53(Al0.5Ga0.5As)0.47 collector-side barrier layer 6. Since there is sufficiently large difference in energy between GAMMA and L valleys in the base layer 7, carriers can be injected from the emitter region to the base region with large energy without causing scattering between the valleys. Accordingly, a material having a large barrier height can be used as the collector-side barrier layer 5. Thus, it is possible to avoid the problem that any part of the device could not maintain the dielectric strength between the base and collector by thermally excited current. The very high speed semi conductor device is accordingly allowed to operate desirably even at room temperature.

Title: Developing device
Inventor: YOSHIDA MINORU
IPC: G03G15/08
Filed: 1987-03-19
Abstract: PURPOSE:To increase an image density while minimizing fogging by executing development while impressing the frequency at which the absolute value of the sum of the electric charge quantity over the entire part of the developer adhering to a non-image region to said region is minimized. CONSTITUTION:An alternate electric field means is provided and the frequency at which the absolute value of the total sum of the electric charge of the developer adhering to the non-image region is minimized is impressed to said region. More specifically, the alternate electric fields are applied between an developer carrying body 16 and an image support 14 to move the developer T back and forth between the developer carrying body 16 and the image support 14. Only the developer T charged sufficiently to a normal polarity flies from the body 16 and contributes selectively to the development when the frequency of the alternate electric fields increases in this case. However, the deposition of the developer T charged to the polarity reverse from the polarity of the normal polarity increases in the non-image region when the frequency increases higher than the prescribed value; therefore, the frequency at which the absolute value of the sum of the electric charge over the entire part of the developer T adhering to the non-image region is minimized is impressed to said part, by which the sufficiently triboelectrostatically charged developer T of the normal polarity can be contributed to the development; in addition, the adhesion of the developer T charged to the reverse polarity is minimized.
