Title: Chemical analysis apparatus
Inventor: HAMAGUCHI TAKEHIKO
IPC: G01N35/02
Filed: 1987-06-30
Abstract: PURPOSE:To discharge the dirt and dust collected at the time of measurement before the dirt and dust infilter a photometric part side by positioning an analysis slide to above a projection window after the slide passes relatively a dust discharge part. CONSTITUTION:After the analysis slide 2 is subjected to specimen dropping, the analysis slide 2 is conveyed successively to the photometric part 77 as a disk 43 rotates in the position direction upon timing up. The dust discharge part 100 is formed to a constant temp. plate 41 on the front side in the disk rotating direction A of the projection window 88 and the analysis slide 2 is positioned to the part above the projection window 88 after the slide passes the dust discharge part 100. An optical system consisting of a projecting part 76 and the photometric part 77 optically measures a change in the density of the color by the reaction of the specimen with the reagent contained in an analysis element 29 of the analysis slide 2 by the specimen dropping. The dirt and dust of the slide 2 are discharged from the dust discharge part 100 even if the dirt and dust are gathered by the movement of the slide and, therefore, the infiltration of the dirt and dust from the projection window 88 to the photometric part 77 and the projecting part 76 is prevented.

Title: Automatic reset circuit
Inventor: ACHINAMI MASAYOSHI
IPC: H03K17/22
Filed: 1985-07-24
Abstract: PURPOSE:To make the circuit operation of an integrated circuit operation stable by using an output signal from a reset circuit to reset an electronic circuit just after power application, inputting the signal to the reset circuit to release the resetting so as to bring the electronic circuit into the standby state thereby eliminating the need for an accessory for the simplicity of constitution. CONSTITUTION:When a power voltage is impressed to a power terminal 10 and exceeds a forward leading voltage VD of the PN junction, a current is fed to an IIL transistor (TR)1 from an injector TR2 and the TR1 is conductive to reset flip-flop circuits 3,31...3n for the initial setting. When the IIL TR1 is conductive after application of power, the output of an inverter circuit 11 is switched to a high level H after a delay time of the inverter. Similarly, the output of an inverter circuit 12 is switched to a low level L after the delay time of the inverter circuit 12. The operations above are delivered to the succeeding inverter circuits to release the resetting of the flip-flop circuits 3,31...3n.

Title: Water pressure-type water level gage
Inventor: ASAMIYA MASANORI
IPC: G01F23/14
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a water pressure-type water level gage whose measuring accuracy is enhanced by a method wherein a measured value is air-column-corrected on the basis of an evaluation value. SOLUTION: The measuring signal S3 of a water-level-gage sensing part 3 is input to a pressure measuring circuit 81 in a water-level-gage conversion part 8 via an outdoor intermediary device 11, and a water level is detected. At the same time, measuring signals S9-1 to S9-5 of water-temperature-gage sensing parts 9-1 to 9-5 are input to a multipoint temperature measuring circuit 82 in the water-level-gage conversion part 8 via an outdoor terminal box 12, and a water temperature is detected. In addition, an air-column-correction factor which is found on the basis of the evaluation value of the water-level-gage sensing part 3 is input to an air-column correction circuit 81 in the water-level-gage conversion part 8.  Then, by a computing part 84 which is installed in the water-level-gage conversion part 8, a temperature correction and a correction by an elevation are applied to the detection water level of the water-level-gage sensing part 3. In this manner, since the detection water level is corrected by combining the air density of an air column with a change in the density of the water temperature with reference to every water depth in the water-level-gage sensing part 3, the measuring accuracy of a water level is enhanced. Especially, a water pressure-type water level gage can be used suitably to measure a water level in a dam or the like whose elevation is high.

Title: Multicolor image forming device
Inventor: TAKAGI MASABUMI
IPC: G03G15/01
Filed: 1988-06-30
Abstract: PURPOSE:To prevent retransfer in the second transfer of an image by forming an image in a color occupying a larger area within the specified area of the image first and then forming an image in another color in the case of forming a two-color image on a transfer sheet. CONSTITUTION:When a toner image is transferred on the transfer sheet whereon another toner image is already transferred, the retransfer occurs hardly when the toner image already transferred occupies a larger area, especially on the side of the forward edge of the transfer sheet where it occurs easily. Such an area is calculated from the red area of an original loaded in a RAM 65, and compared in size with the red area by a CPU 64 based on a difference between the area of the original from its forward edge up to 100mm, for instance, and the red area. The size of image areas in a specified and a remaining color is thus compared within the specified area of the original so that an image occupying a larger area can be formed first. As a result, it can be prevented that toner already transferred on a sheet returns on a photosensitive body and causes irregularities in an image.

Title: Thermal printer
Inventor: SUGIMOTO RYUTARO
IPC: B41J11/66
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide a thermal printer which can prevent a deformation of a recording medium and improve record quality. SOLUTION: In a thermal printer, paper fed from a paper roll 20 is printed in a state that a pair of transfer rollers 22 are out of contact, sequentially sent until the printed part reach the downstream side of a cutter 15 and then cut. The paper 20 is fed backward to return the leading end to a recording position while the pair of transfer rolls 22 are in touch with each other. The thermal printer is kept standby until the recording is resumed while the pair of transfer rollers 22 are kept not in touch with each other. Accordingly, since the pair of transfer rollers 22 are not in touch with each other when the thermal printer is standby, the transfer rollers leave no trace on the paper 20. The roll paper 20 can be maintained smooth, so that a thermal head 47 can print the smooth roll paper 20. Record quality is thus improved.

Title: Drive circuit for stepping motor
Inventor: ODA AKIRA
IPC: H02P8/12
Filed: 1986-07-14
Abstract: PURPOSE:To always stop the rotor of a stepping motor at a specified stop position even in excitation of a few phare by changing exciting current according to the number of excitation phase. CONSTITUTION:In case only one phase of a stepping motor 18, is excited a transistor TR340 is turned ON by output from an I/O port 16, and so reference voltage applied to a comparator 25 is increased, and large current flows to a coil 20. When two phases are excited, then the transistor TR340 is turned OFF, and reference voltage applied to the comparator 25 is lowered, and so current flowing to the coil 20 is reduced. Accordingly, in case of 1-2 excitation system, in one phase excitation, current is increased and an exciting force becomes stronger, and so even with one phase excitation, the rotor of the stepping motor 18 is always stopped at a specified stop position, and the rotor is smoothly rotated.

Abstract: PROBLEM TO BE SOLVED: To solve a combination problem (NP-complete problem) for finding out a satisfactory solution from a huge number of combinations by a smaller number of processes by utilizing a condition that a DNA molecule forms a secondary structure. SOLUTION: In a node type Boolean expression (e.g. an expression for selecting each node from three variables) which is expressed by m variables (e.g. (a) to (f)) and n nodes (e.g. 1 to 10) and in which each of n nodes includes only m variables, each variable is expressed by a DNA molecule having 30 residues, for instance. Each node is peculiarly expressed by a base sequence of linkers connected to both end parts or one end part of a base sequence which represents variables. When DNA molecules to which linkers are attached are mixed with each other, these DNA molecules are mutually connected by oxygen and a product in which n DNA molecules are connected like a chain is generated. A solution can be obtained by removing DNA molecules forming a hairpin structure and not corresponding to the solution from the product.
