Title: Ferromagnetic metal powder coated with toluene polycondensate and manufacture thereof
Inventor: OSHIMA KAZUFUMI
IPC: C09D7/12
Filed: 1984-12-27
Abstract: PURPOSE:To obtain the ferromagnetic metal powder applied to audio-appliances and VTRs which consists of iron mainly and has the exceedingly improved characteristics by using Fe including P, Si and/or B treated with a toluene polycondensate as a main component. CONSTITUTION:The ferromagnetic metal powder fine particles mainly consisting of iron for this use are manufactured by coating a surface part of the fine particle of needle iron oxyhydroxide with a shape retentive component and subjecting the particles to cleaning, drying, and milling followed by calcination and gas-phase catalytic reduction. For the shape retentive components, the reduced iron powder fine particles preferably include P, Si and/or B within a range of P=0.1-5, Si=0.1-5, B=0.1-5 atomic weight percentage to Fe. If the percentage is under the above range, the polycondensation performance of toluene is low and the effect that the characteristic of deterioration with aging of the ferromagnetic metal powder fine particles is improved is diminished. If the percentage is over the range, the polycondensation of toluene progresses too intensively so that the dispersion property during a step of conversion into coating compositions is lowered though affinity for a binder resin is improved.

IPC: G06F19/00
Filed: 1990-10-11
Abstract: PURPOSE:To enable the parallel execution of processes and to perform the processes at a high speed by providing plural arithmetic storage devices which have arithmetic and storage functions and plural connection devices which transfer data between the arithmetic storage devices. CONSTITUTION:A random arrangement generation device 3 in an arithmetic storage device 1 generates arrangement data according to initial arrangement data and sends it to a parallel process device 6 and the data is used as an initial value of arrangement data on each process device. The process device 6 starts with the initial arrangement data and modifies the arrangement data to generate new arrangement data, whose cost is found to select low-cost arrangement data; when the cost does not decrease any more, the process is finished. When all process devices 7 finish their processes, the lowest cost is selected and its arrangement data is a solution of the combination optimization. Namely, arrangement data which are low in cost are searched for in parallel among different arrangement data which are generated at random. Consequently, the processes are performed at a high speed.

Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a ferritic stainless steel strip excellent in ridging resistance, and also allows maintaining a proper bar crown and shape of the strip in endless rolling. SOLUTION: The ferritic stainless steel product, after heating, is rough-rolled into a sheet bar.

The steel strip is then subjected to hot rolled plate annealing, acid pickling, cold rolling and finishing annealing in this turn. In the roughing rolling, the rolling reduction is regulated to >=40% for a pass at least.  In the finishing rolling, for the front member of each set, the rolling reduction and the crown are calculated depending on its sheet bar crown so as to satisfy a predetermined allowable shape condition, and the calculated result is used to determine the draft position and the setting of crown shape controlling actuators; for the succeeding member, depending on its sheet bar crown and the above calculated crown, the rolling reduction is calculated so as to satisfy the predetermined allowable shape condition, and the calculate result is used to change the draft position.

Title: Filling apparatus
Inventor: NAKADA TOSHIYA
IPC: B65B25/04
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To efficiently fill objects to be filled without damaging them by making a structure which vibrates only a packing bag but does not vibrate other members such as a guide and a hopper. SOLUTION: An ejection port 26 on a front wall 21 of a main body 2 is made to correspond to an opening frame 42 of an air intake device 4 while an attaching hole 58 of a swing lever 54 is exposed from a protrusion opening 27 for fixing the main body 2 to cover the air intake device 4 and a vibrator 5. Then a packing bag holding member 6 is fitted into the attaching hole 58 to be fixed to the main body 2. When the air intake device 4 is turned ON, air is fed from the ejection port 26 and a mouth of the packing bag is opened. If an object to be filled is dropped via a positioning member in this state, the object is put into the packing bag, perforations of the bag are broken by its weight and packing of the object is completed. At the time of filling, since the packing bag vertically moves together with the holding member 6, the object is smoothly filled and damage on the object can be reduced.

Title: Damping force-changeable shock absorber control device
Inventor: MATSUMOTO SHUICHI
IPC: B60G17/015
Filed: 1992-09-17
Abstract: PURPOSE:To restrict unnatural motion of a vehicle in changing damping force without increasing frequency of changing the damping force in a shock absorber. CONSTITUTION:A shock absorber 7 is composed to selectively connect/disconnect an auxiliary passage 50 in a control valve 60 to/from a contraction side passage 56 or an expansion side passage 57 by rotation of the control value 60. Hysteresis is given to a threshold value to a size of vertical speed on spring in transition from a control condition where sizes of damping force on the expansion side and the contraction side are different into a control condition where both the damping forces on the expansion side and the contraction side are small to be zero or close to zero. In changing the damping force from the control condition of the large damping force into the control condition of the small damping force temporarily without increasing frequency of damping force changing, unnatural action in springing is eliminated in the case of performing control of restricting change of an attitude, and a large damping force is more positively used to increase damping effect in the case of performing damping control.
