Title: Copying machine
Inventor: YAMADA YOSHIHIRO
IPC: G03G21/00
Filed: 1984-06-11
Abstract: PURPOSE:To assure good cleaning property and high-speed characteristic by selecting a 3-turn process with which image quality is good and a 2-turn process with which a copying speed is high in accordance with the density of an original. CONSTITUTION:The original set to an original platen 8 is irradiated by an exposing lamp 2 and the reflected light is formed an image onto a photosensitive belt 1 by a convergent optical transmission body 3. A photodetector 12 receives part of the reflected light. An integration circuit 13 inegrates the measured value of the detector 12 and a discriminating circuit 16 constituted of an operational amplifier Op, a reference voltage power source Vs, etc. outputs a ''1'' when the density of the original is above a specified level and a ''0'' when the density is below said level. The belt 1 makes two turns under the control of a microcomputer 14, by which the original is copied on a copying machine. The belt 1 is cleaned in the stroke of the 3rd turn. The process for ending the copying stroke is executed if the output of the circuit 16 is the ''0'' and the cleaning stroke is continued until the 4th turn is finished if said output is the ''1''.

Abstract: PURPOSE:To improve magnetic characteristics and tensile strength by combining a specific quantity of ferromagnetic powder and high grade carboxyl acid system lubricant with high polymer nitrile rubber which contains a specific quantity of acrylonitrile and has a Mooney's biscosity of a specific value or above. CONSTITUTION:Nitrile rubber, which contains 10-35% of acrylonitrile and has 60 or above of ML1+4(100 deg.C), in other words has a high Mooney's biscosity (high molecular weight), is introduced. Quantity of combined ferromagnetic powder is 90-95wt%, preferably 90.5-92wt%, of total quantity of the nitrile rubber composite and the ferromagnetic powder. Quantity of combined high grade carboxyl acid system lubricant is 5-20PHR, preferably 8-15PHR. This composite is kneaded uniformly by a kneader at 60-150 deg.C. This mixture is extruded to one direction by a roll forming to be formed into an optional shape such as plate or sheet. When the ferromagnetic powder is not magnetized, a magnetic field is applied after the formation to magnetize it.

Abstract: PURPOSE:To simplify the constitution and to reduce the watt consumption and heating value of an electromagnetic device for a plunger and the like used to control a tape recorder and the like by inserting a resistor in the exciting winding circuit to maintain the state of a movable piece having been attracted. CONSTITUTION:To maintain the state of a movable piece, e.g., a plunger 8 having been attracted by excitation of windings 6 and 7, switches 9 and 10 are changed over to the fixed terminal side. This causes a resistor 11 to be inserted in the exciting winding circuit. Thus, the watt consumption and the heating value on the whole can be reduced.

Title: Remote operation system
Inventor: OOTSUKA MANABU
IPC: B25J3/00
Filed: 1995-05-19
Abstract: PURPOSE: To secure the stability of a remote control system and to smoothly realize the master-slave operation even when the condition of communication is bad between the two and the communication delay is generated. CONSTITUTION: When a grip of a master arm 7 is operated, the inner force data of an inner force sensor 19 are transmitted to a slave 6 through a communication part 4, and a hand of a slave arm 7 is controlled by a controller 8. The force applied to the slave arm 7 is detected by an inner force sensor 23, and the inner force data are transmitted to the master 1 side to generate the same force to the grip of a master arm 2. Because the control is realized by transmitting only the inner force data, the stability of the control system can be kept when the communication delay is generated.

Title: Electronic type gas measuring device, and electronic type gas meter
Inventor: TANAKA SHINICHI
IPC: G01F1/00
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To accurately integrate gas consumptions by reducing an error caused by erroneous integration of passing gas flow rates resulting from pressure fluctuation in an uperstream. SOLUTION: A flow measuring means 100 measures intermittently a physical quantity varying in response to a flow velocity of gas in a gas flow passage 10, and multiplys it by a cross-sectional area of the passage 10 and an intermittent time to measure a gas passing flow rate. A flow integrating means 200 finds an integrated flow rate based on the measured passing flow rates. The first integrating means 14a-1 integrates sequentially the passing flow rates flowing unidirectionally in the gas passage 10, and subtracts a prescribed value from a resulting integrated value every time when the integrated value reaches to the prescribed value. The second integrating means 14a-2 adds the prescribed value in every time when the integrated value reaches the prescribed value to find the integrated flow rate.  When the measured physical quantity is for gas flowing toward a reverse direction in the gas passage 10, a clearing means 14a-3 clears the integrated value.

Title: Sensor
Inventor: ISHITA YOSHIO
IPC: G01B7/00
Filed: 1977-10-12
Abstract: PURPOSE: To improve the refractory, vibration-, shock-, magnetic-shield- and water- proof properties of a sensor by inserting a partition of a ferrite resin into a clearance between an outer casing and a molding material.  
     CONSTITUTION: A partition 8 of a ferrite resin is sandwitched between an outer casing 2 and a molding material 3. As a result, the thermal expansions of the casing 2 and the material 3 are absorbed by the elasticity of the partition 8 thereby to effect the balance in distorsion between the outside and inside of the sensor 1. And, the mechanical distorsion is absorbed to form no clearance in the interface, and the water-proof property of the sensor 1 can be improved against the cooling water. Moreover, a core 4 can be prevented from being broken by the external force, and the shielding effects against the outside magnetic field can be increased together with the absorption of the shocks and vibrations. Still moreover, the directivity of the magnetic field in the upward direction can be strengthened, and the change in the mutual inductances due to the approach of a steel plate can be taken out by a high frequency coil 6 as a discrepancy from a resonant circuit into an electric circuit thereby to detect the change in the distance according thereto

IPC: G03G5/00
Filed: 1978-10-04
Abstract: PURPOSE: To obtain the zinc oxide photoreceptor of good smoothness, superior responsiveness and long life by mixing zinc oxide powder adsorbed with coloring materials and a binder, leaving the same to stand for the specified period, then re-dispersing and mixing the same by using a powerful dispersing device.  
     CONSTITUTION: ZnO powder and coloring materials such as rose bengal, fluorescein, etc. are dispersed in the presence of a solvent such as toluene or xylene by a dispersion method having gentle dispersion functions (e.g., a ball mill is used) to let the coloring materials be adsorbed on the ZnO powder surfaces. Next, a binder such as acrylic resin, styrene resin or other is added and the mixture is stirred and mixed to cover the ZnO photoreceptor with the binder. After the above-mentioned composition is left standing for about 4W7 days, it is powerfully mixed and dispersed by a dispersion method of large dispersion functions (e.g. Kedzie mill method is used) to let the binder deposit evenly on the ZnO particle surfaces. This is coated on a substrate in accordance with ordinary methods, whereby the photoreceptor is obtained.
