Title: Laser light deflector
Inventor: TAMASO HARUO
IPC: H01S3/00
Filed: 1979-04-27
Abstract: PURPOSE:To obtain the light deflector by a rotary mirror which permits the correction of the angle of inclination by detecting the perpendicular position errors owing to the angle of inclination of the rotary mirror by using a photodetector having an optical mask or slit and driving a vertical deflecting system. CONSTITUTION:The photodetecting portion of a photodetector 7 having an optical mask is mounted outside the effective display range of a screen 2 at the scanning start side end of the screen 2. The optical mask 11 being the photodetecting portion of the photodetector 7 is provided with a triangular window shown by ABC, which is so disposed that the side AB becomes perpendicular to the scanning direction of a laser beam 3 and the side BC becomes oblique. As a result of this, the output of the photodetector 12 which performs photoelectric conversion provides the signals of different pulse widths such as a, b, c owing to the perpendicular position luctuations of the laser beam 3. Since the increment of the pulse width is proportional to the perpendicular position fluctuation components, the perpendicular fluctuations, i.e., the angle of inclination of the rotary mirror may be corrected by processing these signals.

Title: Image forming device
Inventor: MURANO SHUNJI
IPC: B41J2/37
Filed: 1992-02-04
Abstract: PURPOSE:To reduce the number of switching means by a method wherein image forming element blocks of the predetermined number are connected batchwise to a time-division drive switching means, and a circuit generating strobe signals of the predtermined number of kinds is provided. CONSTITUTION:A strobe signal is fetched by decoding data of a counter 2 by a decoder 6. When the strobe signal is to be passed through gates 12, 14, the strobe signal of a value in a frequency dividing circuit 4 is passed through one of the gates. Therefore, the strobe signal is divided into two signals STROBE1 and STROBE2. The strobe signals having a width of, for example, 62 clocks are alternately applied to two adjacent LED arrays. The LED arrays L1-L40 are selected by two arrays by switching transistors T1-T20. The arrays are divided into two by alternately applying the strobe signal. Lastly, the LED arrays are driven individually. Since one line is divided into a large number of blocks, an image quality is never deteriorated.

Title: Processing device for photosensitive material
Inventor: FUJITA KATSUJI
IPC: G03D3/08
Filed: 1990-03-05
Abstract: PURPOSE:To prevent the transfer of a processing liquid from a processing tanks to a transporting section existing out of the processing liquid by providing racks, the crossover transporting sections between the respective processing tanks, and the out-of-liquid transporting section from the final stage processing tank to a drying section and providing liquid draining means in the crossover transporting section and on a revolving shaft positioned out of the liquid of a driving transmitting means to the out-of-liquid transporting section. CONSTITUTION:A photosensitive material is admitted by inlet rollers 7 into the processing tank 1 and while the material is transported by the rack 4, the material is subjected to development processing and arrives at the crossover transporting section 8. Since the crossover transporting section 8 is driven by gear connection from the rack, the processing liquid is scooped up successively from the gear 4b of the rack existing in the liquid and is transmitted to an idler gear 13. The photosensitive material enters the processing tank 2 via the crossover transporting section 8 and is transported by the roller of the rack 5. This material is subjected to fixing processing and arrives at the next crossover transporting section 9. The similar liquid draining constitution is provided in the crossover transporting section 9 as well and the similar liquid draining constitution is provided in the out-of-liquid transporting section 10 as well. The transfer of the processing liquid to the gears existing out of the liquid is prevented in this way.

Title: Air electrode material for molten carbonate fuel cell and its manufacture
Inventor: FUKUI TAKEHISA
IPC: H01M4/86
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit the elution of an air electrode material, such as nickel or iron, by forming the air electrode material from covered particles obtained when nickel or iron particles are covered with cobalt or cobalt oxide on their surfaces. SOLUTION: An air electrode material comprises covered particles excellent in molten salt resistance, which are obtained when material particles functioning as an air electrode during battery operation are covered at their surfaces. Nickel is converted into nickel oxide by oxidization process after being assembled into the battery to function as an air electrode. Iron is also converted into iron oxide and functions in the same way. The amount of cobalt or cobalt oxide added as cover material particles is preferably 2 to 30 wt.% of the total weight of the air electrode material particles. At less than 2 wt.%, it is difficult to cover the surfaces of the air electrode material particles uniformly; in excess of 30 wt.%, the amount of the cover material is so large that the material is likely to remain without covering the air electrode material.

Abstract: PROBLEM TO BE SOLVED: To automatically make tap-setting according to the input voltage and change the tap-setting following the fluctuations in the input voltage. SOLUTION: An input voltage is measured (S1), and referring to a table listing tap setting numbers and their appropriate voltage ranges, an appropriate tap setting is made (S2). During the operation, the present tap setting is determined, and the input voltage ACV is measured every second. Referring to the table, a tap setting appropriate to that ACV is determined (S6), and the count Mi corresponding to its tap setting Noi is incremented by one (S7). It is checked whether any of counts has reached a changing value (S8). If it has not, the operation returns to a step S5, but if has, the tap setting is changed to that setting (S11). Then all the integer values are reset to zero, and the operation returns to a step S4.
