IPC: B65H5/02
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prolong the service life of an endless belt by moving a tension roller in a tension releasing direction against the elastic biasing action of an elastic bias means and releasing the tension of the endless belt, when an elevating/lowering frame descends to a non-acting position. SOLUTION: When a cam member 168 of the elevating/lowering means is rotated counterclockwise to a required position, the elevating/lowering frame descends to a descent position through such rotation. Then, an engaging means 254 which is installed in the cam member 168 is made to abut on a means to be engaged formed in a movable member 242. When the cam member 168 is further rotated counterclockwise to the required descent angle position, the engaging means 254 forces the means to be engaged in a required direction, and the movable member 242 is moved to the required position against the elastic biasing action of an elastic bias means 250. As a result, the tension of the endless belt of a transfer belt means is released.

Title: Cylindrical graphite material and its production
Inventor: YASUDA MASAHIRO
IPC: C04B35/52
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a cylindrical graphite material having a large diameter and having reduced variations in properties between various parts by placing carbonaceous members between ungraphitized materials to make the thickness of a packing coke layer uniform in a graphitization process of cylindrical materials in an Acheson-type furnace. SOLUTION: This method is suitable for obtaining a cylindrical graphite material having a diameter of >=500 mm, an unevenness in resistivity of <=5% and an unevenness in thermal expansion coefficient of <=5% in a plane perpendicular to the axis. The graphitization is carried out by placing a fired article to be graphitized in an Acheson- type rectangular furnace made of refractory bricks using coke grains as a packing material, followed by directly energizing them in the direction of furnace length to perform graphitization by resistance heating. By placing carbonaceous members 4 together with packing coke 2 between cylindrical materials 1 to be graphitized and by energizing electrodes 3, an electric current uniformly flows through the layer of packing coke 2 and a graphite material having uniform characteristics is obtained.  The graphite material shows excellent soaking property in a single crystal puller and a heater because the resistivity is uniform over the entire length and in all directions. homogeneous.

Abstract: PURPOSE:To return quickly a peripheral LSI to its original state even in case a part of the peripheral LSI is reset by an electrostatic noise, by generating periodically a control signal to the peripheral LSI from a CPU, and checking the operation of the peripheral LSI. CONSTITUTION:A malfunction preventing method is operated by a command of a CPU1 in accordance with the program in a ROM3. First of all, a prescribed clock is outputted to an A/D converting circuit 11 from a programmable interface (I/F) LSI10. Subsequently, the contents of a display RAM of an I/F LSI20 are read. The contents of a ''0'' address and an 8 address of this RAM are compared, and in case they do not coincide with each, the I/F LSI20 is set to an initial mode, and in case they coincide, a clock signal is ouptutted at evey 100ms to the A/D converting circuit 11 from the LSI10. By repeating the method above mentioned even if the LSIs 10, 20 execute a malfunction by the electrostatic noise, the CPU1 can recognize it immediately, and can set them to a prescribed mode again.

IPC: A01K89/01
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a backlashing outward from a flange part in the spool of a spinning reel. SOLUTION: The cross section vertical to the spool axis 15 of the front end part 7c of a spool body is circular and the cross-section vertical to the spool axis 7c of a flange unit 8 is oval including the circular portion of the front end part 7c. The distance A along the major axis of the oval part from the periphery of the spool body to the periphery of the flange unit 8 is different from the distance B along the minor axis of the oval part from the periphery of the spool body to the periphery of the flange unit 8 (the minimum position) in the difference between the major axis and the minor axis. In this case, a fishline can be wound to the minimum position of the flange unit 8 and the part of difference in distance between A-B of the flange unit 8 is brought to be unable to be wound with the fishline.  Thus, the part of the distance difference A-B causes a wall to hardly occur a backlashing outward from the flange unit.

Title: Anti-skid control device
Inventor: ISHIZAKA MUNENORI
IPC: B60T8/1764
Filed: 1989-04-05
Abstract: PURPOSE:To prevent control accuracy from being degraded by correcting a set time in accordance with the optimum specified regulation at a specified time when the wheel tends to be locked while being in a quick pressure intensifying mode set by the previous unit control so that the control mode is completed before the set time. CONSTITUTION:A controller 50 operates the reference speed based on wheel speeds, wheel acceleration and estimated vehicle speeds from a revolution sensor 54, furthermore with anticipation of a specified slip rate for the estimated vehicle speeds, and then, judges whether or not anti-skid control is required when a brake pedal 12 is depressed. When the friction coefficient of road surfaces is abruptly decreased during the period of antiskid control, and when a quick pressure intensifying mode has been completed before a set time, which is caused by a two-position valve 22 of some certain unit control because of abrupt increase in brake actuating force, the set time for the following time is corrected in accordance with the specified regulation to a greater extent than being corrected in accordance with the normal regulation. By this constitution, the time until the set time for quick pressure intensification is corrected to the value suitable to the friction coefficient of road surfaces and brake actuating force, is shortened, degradation in control accuracy for wheel cylinder hydraulic pressure can thereby be prevented.

IPC: G03G15/20
Filed: 1982-05-21
Abstract: PURPOSE:To obtain cleaning performance with minimum necessary consumption of web and high efficiency, by controlling the supply amount of a cleaning web according to original density. CONSTITUTION:An original 21 on a platen 20 is irradiated by an exposure lamp 22 and a density detection sensor 28 is arranged in the optical path of its reflected light projected on a photosensitive drum 27 to detect the reflection density of the original 21. The original density is measured in a time T1 to hold the measured value as shown by Q1, and a reference wave generating circuit 30(Q2) generates a specific waveform in a time T2. At this time, the period up to when the wave of Q2 crosses the value of Q1 is denoted as t20 and the period up to when the T2 ends after the crossing is denoted as t21, so that the periods t20 and t21 are determined by the value of held Q1. The circuit measures the original reflection density, so the more a white part, the higher the held value Q1. On the other hand, the more a black part, the lower the held value, so the driving time of a web supplying motor is controlled corresponding to t21; and the operation is shortened for an original with a large white part (less toner consumption) or extended for an original with a large black part, supplying the web adequately.

Abstract: PURPOSE:To prevent the occurrence of a crack in the vicinity of an interface between a substrate and a conductor, by having alpha-Al2O3 contained in a calcined conductor to improve the conformability to the rate of contraction between said calcinated substrate and conductor. CONSTITUTION:A paste composition contains Ag or Ag system alloy, or Ag and Pd, alpha-Al2O3 and/or its precursor forming the basic composition of a conductor. 1 to 10vol.% of alpha-Al2O3 is also contained in the conductor. Consequently alpha-Al2O3 is contained in the conductor formed by calcination, and a crack in the vicinity of an interface between said conductor and substrate is suppressed because the rate of contraction by calcination of the conductor approaches another rate of contraction of substrate material to which the conductor is joined.
