Title: Two cycle internal combustion engine
Inventor: TANAHASHI TOSHIO
IPC: F02B27/02
Filed: 1986-06-27
Abstract: PURPOSE:To increase the quantity of fresh air supply in a heavy loading range to improve engine output by providing a driving mechanism for opening an exhaust valve earlier than an intake valve, and a means for swirling fresh air when the fresh air stored in an exhaust port or the like flows backward into a combustion chamber. CONSTITUTION:When an engine is under heavy load, an intake control valve 16 is opened, and an exhaust control valve 34 is closed, and as each of exhaust valves 31a, 31b opens during the downward stroke of a piston, the exhaust is rapidly discharged. On the other hand, as each of intake valves 21a, 21b opens, fresh air is flowed from each of intake ports 20a, 20b into a combustion chamber 2. At this time, pressure in each of exhaust ports 32a, 32b is temporarily reduced to negative value, and the fresh air is therefore stored partly in each of the exhaust ports 32a, 32b and an exhaust manifold 33. After then, the stored fresh air is flowed backward into the combustion chamber 2, and moreover swirled by an eccentric exhaust port 32b and mask 5 on the side of a cylinder head situated above the combustion chamber 2.

IPC: G03G15/04
Filed: 1990-06-07
Abstract: PURPOSE: To reduce a density difference between a transferred image and an original picture by inspecting a toner image being an intermediate image and correcting it as necessary. CONSTITUTION: A carrier 26 where an organic photoconductive layer is formed is pulled out from a supply roll 28, charged by a charge station 60 and restored to an exposure station 46, then the image of an original plate 22 such as a paste-in finished copy is successively projected to form a latent image. Next, the carrier 26 is fed to a developing station 48 through the station 60 which is not actuated and the image is developed with toner to form the intermediate image. After the carrier 26 is temporarily held at a temporary storage station 70, it is fed to a transfer station 50, and the image on the carrier 26 is projected on photoreceptive material 24. The toner density in the inspection area of the carrier 26 passing a toner sub station 64 is detected by a densitometer 214.  In the case the detected density is different from desired density, a controller 32 adjusts the intensity of the electrostatic charge of the carrier 26 and the moving speed of the carrier 26.

Title: Electrostaic potential transferring method
Inventor: FURUICHI MASAYOSHI
IPC: G03G15/05
Filed: 1980-10-25
Abstract: PURPOSE:To transfer the polarization potential of a photosensitive layer by an optical image to a dielectric layer as much as deviation, by transferring and superposing a difference potential between a carrier polarization potential of the photosensitive layer and that corresponding to the optical image upon the partial polarization potential of the dielectric layer. CONSTITUTION:With regard to the states of polarization potentials of a dielectric layer and a photosensitive layer on various conditions, the entire surface is exposed after a common point 5 in time when the photoreceptor is moved in a lateral axis direction, and polarization potentials E1, E2 and E3 held in the dielectric layer are extracted when the partial potential of the photosensitive layer is erased. Here, E1<E2<E3 and those potentials work so that variations of the polarization potential of the photosensitive layer are superposed upon the dielectric layer. Namely, they operate as if the polarization potential of the photosensitive layer by an optical image were transferred to the dielectric layer as much as deviation. Consequently, an original is scanned synchronizing with the photoreceptor and irradiated with the optical image to form an electrostatic latent image on the photoreceptor.

Abstract: PROBLEM TO BE SOLVED: To improve battery performance by adding graphite powder of mean particle size 30μm or less to a negative electrode plate and to improve life performance of the negative electrode plate by preventing lowering of efficiency discharge capacity under high temperature. SOLUTION: Lignin or an organic expander, which is added for preventing lowering of discharge capacity, especially efficiency discharge capacity of a negative electrode plate, is decomposed in an early stage or eluded in electrolyte especially in the case for used under high temperature so that its effects are redused by itself. The quantity of the lignin is increased to cope with it and the consequential lowering of charging acceptance is suppressed by addition of carbon. The graphite powder of the mean particle size 30μm or less is added preferably by 0.3-2wt.% in a negative electrode active material rate as this carbon. Scaly powder is preferred as the graphite material.  This constitution can prevent lignin from being occluded in the graphitte and provide a battery superior in three-hour efficiency discharge capacity and high efficiency discharge capacity in an initial stage and a life test.

Abstract: PURPOSE:To measure accurately a flow rate of gas by letting the gas to be measured to act with a liquid surface of one side of fluid stored in a U-shaped pipe path by suitable amount and obtaining the accompanied pressure variation amount of the fluid. CONSTITUTION:Gas is supplied into a tank 4 through valves 2, 3 and liquid surface 7a and 7b in vessels 5 and 6 are nearly in the same level, and a differential pressure detector 8 outputs a signal of the value corresponding to some pressure value DELTAP1. If the valve 3 is closed, the gas flows in the direction of a dotted line arrow, the liquid surface 7b is raised and the value of the output signal S1 of the detector 8 is increased. The position variation amount of the surface 7b suggests the flow rate of the gas introduced in the vessel 5. Thus by obtaining the position variation amount of the surface 7b, i.e., the pressure variation amount, the flow rate of gas can be measured. A controller 9 detects time points when pressures detected by the detector 8 attain DELTAP1 and DELTAP2, and outputs signal S3 which closes and opens the valve 3 in terms T1, T2... and in terms T'1, T'2... respectively, and calculates the pressure variation in the terms T1, T2..., i.e., the amount of gas flowing in the vessel 5 basing on the signal S1 of the detector 8.

Filed: 1989-06-13
Abstract: PURPOSE:To omit operator's judgement of a sheet material loading limit by automatically exerting control by means of a control means when an operator places image forming sheet materials on a paper feeding part. CONSTITUTION:When many image forming sheet materials 7 are placed on the paper feeding part 1, they are automatically limited by the controlling means 4. That is, when many image forming sheet materials 7 are placed on partition plates 4, they are opened outward in advance.

The operator removes the separated sheet materials 7a which exceed the loading limit, and the loading of the sheet materials 7 are completed. Thus, the operator can omit judgement as for whether the sheet materials 7 exceedes the loading limit or not.

Filed: 1983-08-19
Abstract: PURPOSE:To prevent deterioration in picture quality by performing the exposure of red, green and blue while switching the color at each scanning line and shifting the scanning line position of each color in a direction vertical to a linear scanning direction in a picture recorder using a linear scanning type cathode ray tube. CONSTITUTION:A section 12 to be exposed is subjected respectively to the exposure of red, at first, green next and then blue picture data for one scanning line's share. Thus, the exposure based on a green picture data is overlapped on a constant k-th cycle decided by l or the like at a position subject to the exposure based on the red picture data on the section 12 to be exposed, further subject to the exposure based on the green picture data at the 2k-th cycle and then the exposure by the three color lights is finished. Since the shear in the exposed position by the three color lights is eliminated substantially in this case, an excellent color picture is obtained. Further, the scanning line position in the same color is moved in a direction orthogonal to the scanning line attended with the recording, then the unevenness of the luminous amount of each scanning line is different at each time because of the random property, no stripe is produced.
