Title: External resonance type semiconductor laser
Inventor: MATSUI YASUSHI
IPC: H01S5/00
Filed: 1987-08-26
Abstract: PURPOSE:To obtain a stable oscillation for a returning light by discovering an output light from the end face of an external resonator. CONSTITUTION:A light generated by implanting a current between electrodes 6a and 6b is laser-oscillated with a photoconductive layer 4 as an external resonator. An output light L is produced from a lens 11 from a cleaved face 8b formed at one end of the layer 4, and coupled through an isolator 12 to a fiber or the like. The reflecting returning light of the remote or near end of the isolator 12 is largely attenuated by an attenuation at the end face 8b of the layer 4, an attenuation due to the propagation of the layer 4, and an attenuation due to the coupling of the layer 4 to an active layer 3, thereby performing a stable oscillation.

Filed: 1988-08-26
Abstract: PURPOSE: To selectively assay the expression of a gene by bringing a solid support bound to specific mRNA molecules into contact with the aqueous suspension of labeled microbeads bound to genetic probe molecules.  
     CONSTITUTION: A solid support bound to mRNA molecules containing specific target mRNA molecules is brought into contact with the aqueous suspension of labeled microbeads bound to genetic probe molecules. The genetic probe molecules each has a sequence capable of forming a hybrid with a sequence which comprises the specific target mRNA molecules for performing the assay and which characterizes the target mRNA. Thereby, the labeled microbeads are selectively bound to the specific target mRNA molecules bound to the support and used for performing the assay. The solid support is separated from microbeads no bound to the target mRNA molecules.

Title: Film formation of powder
Inventor: NAKANISHI TOSHIO
IPC: B05D1/04
Filed: 1982-12-01
Abstract: PURPOSE:To obtain easily a uniform film by blowing upward the powder contained in a conductive box impressed thereon with the voltage to the polarity reversed from a high voltage impressed on a substrate to said substrate and sticking the powder thereon. CONSTITUTION:A high voltage is impressed on a substrate 1 from a high voltage power source 2. On the other hand, a box body 3 constituted of a conductive material is connected through the ground to the negative pole side of the power source 2 and a fan 4 is disposed. Powder 5 of a high polymer material or the like is put in the box body 3, and when the powder 5 is blown upward by starting the fan 4, the high voltage electric field between the substrate 1 and the body 3 is generated, by which the water molecules in the air are ionized and the ions having a negative polarity are stuck on the powder 5. The powder 5 is thus ionized and is stuck electrostatically on the substrate 1, whereby a film is formed.

Title: A/d conversion optimization circuit
Inventor: YAMAGUCHI SHIGERU
IPC: H03G11/02
Filed: 1994-09-06
Abstract: PURPOSE: To take out only video components from video signals and to improve the accuracy of picture resolution. CONSTITUTION: A sample pulse generation circuit SPG generates sample pulses based on inputted video signals and a sample-and-hold amplifier IC1 samples the black level of the video signals by the sample pulses and outputs the black level voltage. When the video signals and the black level voltage are added, the black level of the video signals is fixed to 0V. A video amplifier IC2 amplifies the video signals to the reference voltage of an A/D converter. When signal components less than 0V are removed from the video signals by diodes D1 and D2, only video information is taken out.

Title: Picture recording control method
Inventor: UCHIDA KOJI
IPC: G03D9/00
Filed: 1989-08-21
Abstract: PURPOSE:To improve the efficiency of image formation by making the synchronous control of a heating drum and a recording material more accurately at a high speed. CONSTITUTION:As for the recording material 16 carried at first, since the synchronous timing of the recording material 16 and a peeling groove 80 is taken in the vicinity of a position where the recording material 16 abuts on the heating drum 40, they are accurately synchronized and unnecessary stop period can be eliminated. In consecutive picture recording, by detecting the peeling groove 80, where the leading edge of the recording material carried in the order of n = k - 1 (k = 2, 3,...) abuts on, at a second prescribed position X, the carrying of the recording material 16 carried in the order of n = k and having been stopped at a prescribed position is started. Before the completion of peeling the recording material carried in the order of n = k - 1, the leading edge of the recording material carried in the order of n = k is overlapped with the peeling groove 80, and the consecutive picture recording can be carried out without stopping the heating drum 40 nor requiring its excessive rotation. Thus, the synchronous control of the heating drum and the recording material can be made more accurate and swifter.

Abstract: PURPOSE:To obtain a highly reliable and economic series/parallel switching alternator having simple constitution by a constitution wherein first and second three-phase full-wave rectifiers output three-phase full-wave rectified currents in parallel upon interruption of each unilateral switch to bring about parallel connection of both three-phase armature windings and the output current is doubled. CONSTITUTION:At first, rotational speed N is read out through a sensor for detecting the rotational speed of the rotary shaft of a generator and a judgment is made whether thus read out rotational speed N is within a range of 2000-3O00r.p.m. If it is not within the range, a gate trigger voltage VG is pulled to High level and silicon control rectifiers 5x, 5y, 5z are turned ON thus connecting first and second three-phase armature windings 1, 3 in series and outputting a doubled voltage to the outside. When the rotational speed of the generator is within that range, the gate trigger voltage VG is pulled to Low level and the silicon control rectifiers 5x, 5y, 5z are turned OFF thus connecting the first and second three-phase armature windings 1, 3 in parallel and outputting a doubled voltage to the outside.

Title: Combustion appliance
Inventor: ITO HIDEKI
IPC: F23N5/02
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To improve a service life of a combustion appliance by reducing a burner burden by minimizing the frequency of turning on and off combustion operation of a burner. SOLUTION: The combustion appliance comprises a heat exchanger for producing hot water by combustion in a burner, a hot water temperature- measuring device, temperature-setting means, and a controller for controlling combustion operation. Combustion operation of the burner is turned on and off so that a preferable temperature range of hot water is controlled according to a state in use of the combustion appliance. When a measured temperature T of the temperature-measuring device is above a specified temperature in a specified time, the temperature range is enlarged by varying a combustion-off temperature Tof and a combustion-on temperature Ton. After that, when a measured temperature T is not reached to a combustion-off temperature Tof in another certain time, a temperature range after varied is returned to an initial temperature range.  Such a control allows frequency of on-off of burner combustion to reduce even at the time of light load with a steep temperature increase.
