Title: Process unit
Inventor: ONO KUNINORI
IPC: G03G15/00
Filed: 1990-05-15
Abstract: PURPOSE:To make a process unit compact by attachably/detachably and selectively mounting each of a developer cartridge whose bottom aperture part is sealed so that it can be unsealed and contains two-component developer inside and a toner replenishing unit at the upper part of a developing chamber. CONSTITUTION:An image is formed by using the two-component developer 27c consisting of carrier and toner. Then, a developer cartridge 27 which supplies the developer 27c containing the carrier which is hardly consumed after it is thrown in a developing tank 24c once is constituted so as to be attachable/ detachable. After throwing the developer 27c, the cartridge 24 is discarded and the toner replenishing unit 28 is attached instead. Thus, a dead space occupied by an unnecessary member is eliminated and the process unit is made compact.

Filed: 1989-05-17
Abstract: PURPOSE:To avoid the effect of an interlinkage magnetic field and to prevent the fluctuation of reference voltage by forming the first and second membrane resistor parts formed on a substrate in a film state from a nickel-chromium alloy. CONSTITUTION:A reference voltage generating apparatus 16 is constituted by forming the first and second membrane resistor parts 16a, 16b having a meandering shape to an insulating substrate 11 in a state connected in series using an alloy consisting of about 90% of Ni and about 10% of Cr. When a magnetic field is interlinked with the substrate 11, difference is generated between the resistance values of the first and second magnetic resistor parts 12a, 12b corresponding to the direction of the interlinkage magnetic field and the voltage Va from a magnetic resistor element 12 is varied and, therefore, the voltage Va is compared with the reference voltage V0/2 from the apparatus 16 by a comparator 22 to detect the direction of the interlinkage magnetic field. When a magnetic field is interlinked with the element, a magnetic field is also interlinked with the resistor parts 16a, 16b to generate magnetoresistance effect according to circumstances and there is possibility such that the resistance values of the resistor parts 16a, 16b are changed and reference voltage is varied from V0/2 but, by using the NiCr alloy, the fluctuation of the voltage V0/2 is prevented even when a magnetic field is applied.

Abstract: PROBLEM TO BE SOLVED: To conduct stable AGC by detecting a binary symbol area from a demodulation signal so as to generate an AGC signal based on a signal level of the demodulation signal obtained for a detection period of a binary symbol area. SOLUTION: Information data to be sent are converted into multi-value symbol series and a symbol resulting from adding periodically a binary symbol area HDP consisting of a binary symbol to the multi-value symbol series is subject to multi-value digital modulation by a 16-value VBS modulator 40 and the result is sent to a transmission line 15.

Title: Preceding car follow-up control device
Inventor: HIGASHIMATA AKIRA
IPC: B60W10/18
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent continuous operation for a long time of braking state in a car computing target car speed for conforming the distance between cars against a preceding car to the target distance, and controlling an engine and a control device, by releasing follow-up control when the time integral of braking force exceeds the reference value. SOLUTION: During running of a care, the distance L between the own car and the preceding car is measured based on output of a distance between cars sensor 1 using laser rays by a distance measured signal processing part 11, and the speed VS of the own car is detected based on output of a car speed sensor 2 by a car speed signal processing part 21. A target distance between cars L* and a target car speed V* are computed based on the distance between cars L and the own car speed VS by a preceding car follow-up control part 50, and braking force and speed change ratio are controlled so that the own car speed VS becomes the target car speed V* by a car speed control part 51. In this case, braking force of a brake device is time integrated, and when the time integral value exceeds the reference value, follow-up control is released, and hence the brake is prevented from becoming in the fade condition on a long descending slope.

Title: Manufacture of r-fe-b magnet
Inventor: KANEKO YUJI
IPC: B22F3/02
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To realize orientation in a magnetic field, which can realize powder orientation with a higher magnetic field, without regulation in the space size of a generated uniform magnetic field. SOLUTION: Superconducting coils 4 arranged at the outer periphery of a mold 3 with which raw material powder is filled are kept to a very low temperature state. Thus, a superconducting magnet generates magnet field strength which considerably for exceeds 20 kOe can be obtained. Since the size restriction of a uniform magnetic field space is not given, orientation magnetic field strength can be increased considerably by using the superconducting coils. Then, the orientation degree of R-Fe-B raw material powder can largely be improved, and the permanent magnet of high ability can be manufactured easily.

The transfer member is heated to a constant set temperature by the heater 40 which is brought under the temperature control of a temperature sensor 41 detecting its temperature. This set temperature is determined by the glass transition temperature of toner resin and the permissible surface temperature of the photosensitive body.

IPC: B63H5/08
Filed: 1981-08-07
Abstract: PURPOSE:To improve the efficiency of the propellers of an ordinary ship, by making the distance between two propeller shafts smaller than the diameter of the propellers and by prescribing the number of the blades of each propeller to be two, three or four and by synchronously rotating the propellers. CONSTITUTION:The torque of a single main engine 4 is transmitted to propellers 1, 1 through a transmission mechanism 5 and propeller shafts 3, 3. The number of the blades 2 of each propeller 1 is prescribed to be two, three or four. The outside diameter of each propeller is made large but and the surface area of each blade is made small so that the blade is slender and the surface area of the developed propeller is small. The efficiency of the propellers 1, 1 is thus improved. The distance between the propeller shafts 3, 3 is made smaller than the outside diameter of the propellers 1, 1. The rotation loci of both the propellers are overlapped with each other. The propellers are synchronously rotated in the opposite directions to each other. According to this constitution, a danger of stern vibration is eliminated and a very high two-shaft propelling effect is produced.

Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a lens system and the size of a camera incorporating a range finder by applying a diffraction optical element to a range-finding lens system. SOLUTION: In the range-finding lens system, a light projecting lens system or a light receiving lens system is provided with the diffraction optical element constituted in such a manner that both surfaces r1 and r4 are of plane surfaces and at least one of them is of a diffraction surface. For instance, a plate lens having a thickness of 1mm is used and all power is concentrated on the surface r1 . The light emitting part of an infrared ray emitting diode(IRED) is covered with a planar resin package. The surface r1 paraxially has the total positive power with respect to rays of light at a projection angle of 0 deg., but the peripheral part of the surface r1 has a strong divergent action. The surface r4 is paraxially powerless, but the peripheral part of the surface r4 has a strong convergent action.  Therefore, the surface r1 has such a shape that negative power gradually becomes stronger as it goes further away from the center. The surface r4 has such a shape that the positive power gradually becomes stronger as it goes further away from the center.
