Title: Cleaning device for electrophotography
Inventor: NISHIMURA MATSUOMI
IPC: G03G21/10
Filed: 1977-12-28
Abstract: PURPOSE: To prevent the developer from spilling over by transferring it into the quartered circumferential part to hold temporarily, by pressing the end part of elastic cleaning plate blade which  abuts against the image carrier plane against the carrier plate by constituting a protruding part  composed of quartered circumferential conductive elastic wall.   
     CONSTITUTION: A blade 2 supported on a stiff holder 1 is sufficiently pressed against a photosensitive drum 3, which is an image carrier, at blade main body part 2a and protruding parts 2b  provided at both ends thereof. The blade part 2a is more strongly rubbed against the blade main  body, so that the toner remaining on the photosensitive drum may be sufficiently removed. Furthermore, since the end part protruding parts 2b are in perfect contact with the photosensitive  drum due to extreme elasticity, the toner is kept from spilling over the end parts. The part collecting the toner at said protruding parts 2b makes up a wall composed of quartered circumferential  plane. Since the back side of the circumferential wall is notched, an elastic, thin wall is constituted. The toner collected in the circumferential wall is caused to move in the central direction of the  blade 2 along the locus of this quartered circumference, thus preventing the toner from spilling  over the blade ends.

IPC: H01L29/732
Filed: 1986-07-08
Abstract: PURPOSE:To improve a current amplification factor by making the depth of a collector larger than that of an emitter in a lateral transistor. CONSTITUTION:A mask 6 having openings in a collector forming region and an emitter forming region and a resist mask 7 covering regions other than the collector forming region are formed, and P-type impurities are implanted deep to form a collector 8. Next, the resist mask 7 being removed, a resist mask 9 is so formed as to cover regions other than the emitter forming region, and P-type impurities are implanted shallow to form an emitter 10. By making the depth of the collector 8 larger than that of the emitter 10 in this way, a facing area is increased, and a collector current is made to flow easier than a base current.

Title: Polyester resin composition for food packaging film
Inventor: MASUDA YUKARI
IPC: C08K5/15
Filed: 1995-06-27
Abstract: PURPOSE: To obtain a composition that is excellent in selftackiness in a wide temperature range from a low temperature to a high temperature, and in heat resistance, cuttability, and transparency, and does not release toxic gases when burnt. CONSTITUTION: There is provided a resin composition made by adding, to a polyester resin (A), 0.1 to 15wt.% plasticizer and 0.1 to 50wt.% tackifier (B). As the polyester (A) to be used, preferably a polyester having a melting point peak value of 170 deg.C or over can be mentioned. As the plasticizer, particularly a combination of a polyester plasticizer with an epoxy plasticizer is preferable because the effect of rendering a film flexible is high and a small amount thereof can satisfy the intended effect. Since tackifiers make the compatibility with the polyester resin poor, it is required to consider the compatibility with the polyester resin, and in this regard preferably use is made of rosin resins, phenolic resins, and cumarone/indene resins.

Title: Method of automatically controlling focus in electron ray device
Inventor: YOKOUCHI HISATAKE
IPC: H04N5/232
Filed: 1983-09-02
Abstract: PURPOSE:To enable stable and high-speed controlling of the focus to be performed by changing the focal distance of an electron lens in m stages, approximating focal information extracted from the wave form of detection signals to an n-order polynominal by the method of least squares and obtaining an optimum position from the approximation formula. CONSTITUTION:Among two focus-controlling lenses (O) and (OS), first of all, the current (Io) of the O lens is set for a predetermined level. After that, the current (Ios) of the OS lens is changed in 9 stages and a mark wave form signal for each stage is taken in and subjected to differentiating twice in order to detect the degree of sharpness. After that, a quadratic or cubic curve most similar to each Ios and the degree of sharpness detected is selected. Then when the maximum value of the selected approximate curve is located near the center of the variation width of the 9 Ios levels, the Ios level corresponding to the maximum value is extracted and the OS lens is adjusted to zero for example. At the same time, the extracted current level (Ios) is calculated into the current level of the O lens and the obtained current level (Ioj) is fed in the O lens. When the above maximum value does not exist near the center, the current level (Io) of the O lens is a little changed and detection of the focus is performed in the same manner as above.

Title: Failure diagnosing apparatus for electric circuit
Inventor: NAKAJIMA HITOSHI
IPC: G01R31/02
Filed: 1993-06-30
Abstract: PURPOSE:To provide a failure diagnosing apparatus for an electric circuit which can highly reliably diagnose whether or not a short circuit exists without an increase in a size and a cost for transistors, resistors, capacitors, etc., in an internal circuit of an ECU (control unit) and without causing a processing burden on a CPU. CONSTITUTION:While a transistor 22 is OFF and a transistor 24 is OFF by communication from an ECU 12A to an ECU 12B, a very weak voltage 5V is applied to a short circuit diagnosing circuit 32, and by measuring a potential at an output terminal 12Aa, whether or not a short circuit exists is diagnosed between the output terminal Aa and an electrode 16a of an electric machine 16. Thus even if a short circuit, exists at the time of diagnosis, a large current is prevented from flowing to the short circuit diagnosing circuit 32. By diagnosis of the short circuit while the machine 16 is not operating, operation of the machine 16 is inhibited when a short circuit exists, so as to prevent an internal circuit of the ECU 12A from being damaged.

Title: Method for preventing clogging of exhaust gas recovering device
Inventor: HATSUYA EIJI
IPC: C21D1/76
Filed: 1989-06-26
Abstract: PURPOSE:To regenerate an H2-contg. exhaust gas and to effectively utilize this gas for the denitriding treatment of a metallic material by cooling the exhaust gas generated at the time of denitriding the metallic materials by the H2-contg. gas with water to a specific temp. and dissolving the gaseous NH4CI contained in the exhaust gas in the water and thereby removing the same. CONSTITUTION:An atmospheric gas contg. H2 is supplied into a heat-treating furnace 1 contg. the metallic material, such as iron powder, and is heated to, for example, 450 to 700 deg.C to remove the N in the iron powder as NH3. A slight amt. of gaseous HCl intruding into the heat treating furnace 1 reacts with the exhaust gas and the NH3 changes to the NH4Cl. The exhaust gas which contains this NH4Cl and in which the H2 remains is passed through a dust catcher 10 and is introduced into a washing device 2 where the gas is cooled from temp. exceeding 335 deg.C down to <=100 deg.C and the NH4Cl in the exhaust gas is dissolved away into the water of the washing device 2. Mists are removed from the gas by a mist separator and thereafter, the gas is recovered into a recovering tank 9. This gas is reutilized again as the gas for denitriing of the iron powder. The exhaust gas is recovered without requiring the labor for cleaning the NH4Cl deposited in the pipings and valves of the exhaust gas recovering device.

Title: Separator of solid high polymer type fuel cell and its manufacture
Inventor: KATO HIDEKI
IPC: H01M8/02
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To stably generate power over a long time by forming a separator with a resin mold body containing carbon powder and a thermoset resin as constituents and by setting the concentration of impurities contained in the resin mold body to a specific vague or less. SOLUTION: Impurities contained in a resin mold body are specifically base metal ones and the concentration of ones having ionizing tendency larger than that of Hg is set to 100 ppm or less. Those kinds of metals are K, Na, Ba, Ca, Mg, Al, Fe, Ni, Sn, Pb, Cu, Si and P, and easily ionize in the presence of hydrogen ions to adhere or attach to the inside and surface of an ion exchange film so that the film is poisoned. Therefore, the lower the concentration thereof is, the more the risk of the poisoning is reduced, so that it is preferably set to 0.01-5 ppm. Accordingly, it is preferable that carbon material used as a starting material is processed with a halogen compound, for instance, a chlorine gas at a heating temperature of around 2000-2300 deg.C.
