Title: Production of crystal
Inventor: HASHIMOTO IORI
IPC: B01D9/02
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To stably produce a product having a desired average grain size by controlling the classification flow rate against the fluctuation of the average grain size of the product in order to suppress the continuous oscillatory phenomenon of grain size distribution in a crystallization apparatus. SOLUTION: When a product crystal having a desired average grain size is effectively produced, the continuous oscillation of the average grain size and the concentration of the slurry in a crystallization can are suppressed by controlling the classification flow rate according to the average grain size of the crystal which is pulled out from a product pulling out line, and the concentration of the slurry in the crystallization can and the average grain size of the product crystal are controlled by changing the processing range of the classification flow rate.  At this time, the average grain size of the product crystal is controlled by continuously measuring in on-line from measured values obtained by a grain size monitor or the like which is provided at the product slurry pulling out line, and further the classification flow rate is controlled by a flow rate controlling valve which is disposed at a line for supplying classification flow to a classification leg. Thereby, the crystal having the desired average grain size is produced in a high yield and the manual operation for controlling the average grain size becomes non-essential.

Filed: 1989-06-16
Abstract: PURPOSE:To make accurate magnetism corrections by calculating magnetism correction quantities from specific equations when an angle variation quantity found from a rotary sensor output exceeds a constant value within a certain time, and calculating an azimuth angle. CONSTITUTION:An azimuth sensor 2 finds two orthogonal earth magnetism signal components Vx and Vy and the rotary sensor like a gyro 3 outputs angular velocity information omega, which is integrated to find the angle variation quantity theta. Those pieces of information are sent to an MPU1, which performs calculation processing. When this angle variation quantity theta exceeds the constant value thetas within the certain time Te, the magnetism correction quantities Zx and Zy are calculated by using the equations I and II and the azimuth angle alphais calculated by using an equation III at the same time or different time. For example, when an automobile makes turn an intersection at an angle of about 90 deg., etc., the magnetism correction quantities Zx and Zy are found and those results are used to find the azimuth angle alpha after magnetism correction automatically.

Title: Motor driven driving device or generting device
Inventor: FURORIAN RAURU POPESUKIYUU GET
IPC: H02K57/00
Filed: 1981-09-29
Abstract: An electromotive drive, primarily for use in vehicles which use storage batteries, is described, which has a control and regulation device for re-charging the batteries when the acceleration of the drive is reduced as well as, for example, when the vehicle is being slowed down by braking or is being driven down an incline. The drive encloses radially controlled, movable pistons (6) or heavy weights in a rotating flywheel which are mostly borne in cylinders (5) which are surrounded by coil devices (8) which receive rhythmic current pulses via the control device. On rotation of the rotating flywheel, the pistons (6) or free-piston type, heavy, radially pulsating weights, are pressed centripetally towards the drive axis by compression springs (7) acting against the centrifugal force on the pistons, such that, on reaching the operating speed or the speed of rotation corresponding thereto, the said centripetal forces in each piston position maintain a static-dynamic radial balance with the centrifugal forces of the rotating piston weights, which the control force can easily influence by means of the said coil windings (8). In other respects, the unit represents an electrical D.C. machine which is operated in the pulse mode and the multi-quadrant mode, generally by means of a D.C. pulse transformer. During the rotation of the armature (2) at a practically constant speed, - even in the case of acceleration, since only the piston frequency need be increased then-, rapid displacement will occur in the partial period of the piston radial pulsation in which the piston controls externally, battery current being fed both to the abovementioned coil windings (8) about the piston cylinder as well as to the other D.C. windings of the armature (2) and of the pole (3). In addition, current energy is stored as a quasi-potential reserve in overcoming the, in this case time-variable, increasing moment of inertia or flywheel moment GD<2> of the flywheel. In the opposite phase, or time period of the piston pulsation with its centripetal movement, the battery current is switched off, the only effective drive then being, on the other hand, the inertial-mechanical rotation-maintaining torque of the rheonomously reducing rotor speed acceleration energy. <IMAGE>

IPC: B29C48/67
Filed: 1985-07-12
Abstract: PURPOSE:To prevent material from adhering to the tip of a torpedo and harden ing at the tip by a structure wherein the tip of the torpedo is made to be eccen tric to the center line of the axis of a screw. CONSTITUTION:A torpedo 1 is mounted at the tip of a screw 3, which is rotatingly driven and at the same time reciprocatingly driven backward and forward. The torpedo 1 is mounted to the screw by screwing the male thread portion at the tip of the screw 3 into the female thread hole 9 provided on the inner periphery of the torpedo 1. The tip 2 of the torpedo 1 is pointed and set to be eccentric to the center line (c) directing to the axial direction of the screw 3. Because of being eccentrically pointed, the tip 2 rotates at a certain peripheral speed and consequently the adhesion of material to the tip 2 becomes hard and no hardening of the material at the tip 2 results and accordingly the kneaded part with favorable quality is obtained and at the same time the dischargeability through a discharge nozzle 4 is improved.
