Patent JP-S63136590-A (JP)
Title: Semiconductor superlattice
Inventor: IWATA HIROSHI
IPC: B82Y20/00
Filed: 1986-11-27
Abstract: PURPOSE:To inject carriers effectively into a quantum well fine line, and to obtain a semiconductor laser and an electronic device having high performance by forming one or more of quantum well structure constituted of a quantum well plane composed of a semiconductor on a plane and the quantum well line made up of a linear semiconductor and making the potential energy of the quantum well line lower than the quantum well plane. CONSTITUTION:The greater part of holes and electrons each injected from a P electrode 18 and an N electrode 19 are injected to a quantum well plane 14, but they flow into quantum well lines 15 because the potential energy of adjacent quantum well lines 15 is low. Since both holes and electrons arc confined in two dimensions and brought to a false one-dimensional state in the quantum well lines 15, each density of the states is concentrated into narrow energy regions, and the recombination spectra are narrowed extremely. Accordingly, all carriers effectively contribute to laser oscillation, thus acquiring a semiconductor laser having extremely small oscillation threshold currents.

In this construction, a drive current is selectively supplied to each heating resistor 10 through these electrodes. In addition, each of the heating resistors 10 has a smallest- width part 10a from a point of view along the electric current path thereof (in a direction of an arrow 13). The adjacent heating resistors 10 are disposed so as to be longitudinally staggered with each other.

Filed: 1994-11-17
Abstract: PURPOSE: To realize the setting of the attribute values of printing control setting information at the desired timing of a user irrespective of the existence of print job and the presence and absence of error in a printer which prints and outputs images in response to the received print job. CONSTITUTION: When the displaying of printing control setting information is instructed from an operating panel 17, a displaying controlling part 19 fetches the printing control setting information from a setting storage part 14 and displays it on a displaying part 17b. In this case, when a user inputs the attribute values of the printing control setting information by the operating panel 17, a print process part 13 rewrites the printing control setting information of the setting storage part 14. The displaying controlling part 19 displays re-written printing control setting information in the displaying part 17b.  At the same time, when print information is instructed to be displayed from the operating panel 17, the displaying controlling part 19 fetches the print information on the print job under processing from a control table 18 so as to display these informations on the displaying part 17b.

Title: Display system and apparatus for moving picture signal
Inventor: NEMOTO KEIJI
IPC: G06T13/00
Filed: 1989-10-31
Abstract: PURPOSE:To attain far natural display in comparison with the case of inverted time of a displayed field by displaying succeedingly a preceding field and a field generated from now when the output of the field to be displayed next is not in time. CONSTITUTION:An output section 1 outputs continuously a moving picture signal 101 in the unit of fields. When the output of an even number 102b is finished and the output from the output section 1 to the storage section 2a is not finished, the selection output of an odd number field 103b and an even number field 102b is repeated. The odd number field 103b is generated from the even number field 102b and a picture of the same time is formed as a moving picture signal, then the moving picture is stopped in a natural form and displayed by displaying it repetitively. Thus, when the output of the moving picture signal 101 from the output section 1 is not in time, the far natural moving picture signal is displayed in comparison with the repetitive display of the field with the inverted time.

Title: Semiconductor device and manufacture thereof
Inventor: UNNO YUKARI
IPC: H01L27/11
Filed: 1992-10-22
Abstract: PURPOSE:To obtain electric connection between a gate electrode and an impurity diffusion layer having different conductivity types to each other, by enabling the electric connection between the gate electrode and the impurity diffusion layer, using metal-containing material for forming polycide structure. CONSTITUTION:After a P<+> diffusion layer 107 is formed, a tungsten silicide layer 108 is deposited on the whole surface by sputtering as electrode wiring material. Patterning of a polycrystalline silicon layer 104 and a tungsten silicide layer 108 is performed at the same time. Consequently, it becomes possible to connect a gate electrode (gate electrode 103, polycrystalline silicon layer 104) with the impurity diffusion layer 107 electrically. Consequently, even when it is necessary to connect a 2-layer gate electrode of one conductivity type containing a polycrystalline silicon layer with an impurity diffusion layer of the other conductivity type, as in the case of the CMOS circuit of an SRAM memory cell, metal wiring other than the 2-layer wiring becomes unnecessary, and it is possible to devote greatly to the miniaturization of elements.

Title: Switching device
Inventor: ARINOBU ICHIRO
IPC: H01H9/16
Filed: 1988-11-11
Abstract: PURPOSE:To improve the reliability of display under the condition of an abnormality by discriminating tripping and other conditions of a remote-control breaker, etc. CONSTITUTION:If an overcurrent flows to a load connected with a main circuit load terminal 29, or when a shortcircuit occurs, under the ON condition, a breaking switch 31 is opened by a tripping mechanism, and a common terminal COM of a microswitch 24A gets connected with a thermal close terminal NC, so full-wave current flows to a full-wave detecting circuit 12. A detecting means 12 detects a tripping condition of an operated switching means by this full-wave current to display the tripping condition by the detecting output. At this time, a display prohibiting means 16, 17 prohibits display action of an ON display means 4 and an OFF display means 7. The reliability of display under the condition of an abnormality of tripping can thus be improved.

Title: Frequency modulator
Inventor: IZUMI HIDEO
IPC: H03L7/22
Filed: 1989-11-02
Abstract: PURPOSE:To obtain a frequency modulator capable of applying frequency modulation at a broad band, with high frequency stability and excellent response by providing 1st and 2nd PLLs applying prescribed operation. CONSTITUTION:An LPF 12 with a very large time constant is used and a loop response frequency of a PLL 101 is sufficiently lower than a frequency of a modulation signal. A frequency division ratio of a frequency divider circuit 5a in a PLL 100a is selected corresponding to a desired carrier frequency by a carrier frequency changeover circuit 6. The oscillating frequency of a VCO 13 in the PLL 101 and the oscillating frequency of a VCO 4 in the PLL 100a are both modulated by a modulation signal and the oscillating frequency of the VCO 4 in the PLL 100a is outputted as a modulated signal. Since the loop response frequency in the PLL 101 is sufficiently low, even when the frequency of the modulation signal is low, the output signal M3 of the VCO 13 is sufficiently frequency-modulated by the modulation signal without responding to the frequency change in the modulation signal.
