Title: Deburring device for band steel plate
Inventor: ONO TAKUMI
IPC: B24B9/00
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a qualitative defect such as a flaw in a band steel plate itself by pushing a columnar grinding wheel or a brush or the like against a passing band steel plate in a rotatable structure, rotating the grinding wheel by using force when the band steel plate advances, and removing a burr of a band steel plate end part by its torque. SOLUTION: In a condition where a band steel plate 1 is carried in the plate passing direction 2, the band steel plate 1 is contacted at a contact point 8 with a rotary grinding wheel 6, and the rotary grinding wheel 6 is pushed from the band steel plate 1, and autorotates with a grinding wheel rotary shaft 7 as the center. In this way, when the rotary grinding wheel 6 autorotates, at the contact point 8 of the rotary grinding wheel 6 and the band steel plate 1, a band steel plate edge part receives contact force 4 from the rotary grinding wheel 6. An edge burr part of an under surface of the band steel plate 1 is eliminated by this contact force 4.  This contact force 4 can be broken down into force 5 parallel to the plate passing direction of the band steel plate 1 and force 3 which is perpendicular to the plate passing direction and turns to the outside of the band steel plate 1, and chips and rubbish by the rotary grinding wheel 6 are removed outside, and a burr is also pushed outside.

Title: Electric dust collector
Inventor: SHIMODA MAKOTO
IPC: B03C3/40
Filed: 1977-10-24
Abstract: PURPOSE: To improve dust collecting efficiency by setting controller-electrodes in the dust collecting space formed between a dust-collector-electrode and a discharge electrode, and by controlling ion wind.  
     CONSTITUTION: When a controller-electrode 6 is impressed in high voltage with the same poles of high voltage that impresses a discharge electrode 2, the electric field formed by the discharge electrode 2 is affected and concentrated in a narrow area, thereby narrowing also ion wind from the conventional dashed-lined ion wind 4 to full-lined ion wind 7. Since the energy of ion wind 7 generated from the discharge electrode 2 is thus prevented from being dispersed, the dust driving force by ion wind 7 toward the dust-collector-electrode 1 is firmly maintained. Thus, the dust collecting efficiency is improved.

Title: Magnetic recorder
Inventor: SHIMIZU HIROKI
IPC: G11B5/02
Filed: 1982-07-22
Abstract: PURPOSE:To ensure the magnetic recording to obtain a reproduced sound of high quality, by providing two magnetic head cores of different track widths to record the high frequency signal to a narrow track with a low bias as well as to record the full band signal to a wide track with a high bias and therefore assuring satisfactory high band characteristics at a high level. CONSTITUTION:The output signal of an HPF5 is superposed with a low bias current supplied from a bias oscillator 6 and forms a narrow track 7b with a magnetic head 4b. While the full band signal of the output of a sound recording equalizer 2 is superposed with a high bias current supplied from a bias oscillator 3 and forms a wide track 7a with a magnetic head 4a. Thus a sufficiently large output of reproduction can be extracted as shown by a curve II for the high frequency signal recorded by the head 4b, and the satisfactory high band characteristics can be obtained at a high level in particular. This compensates a low output when the high frequency signal among the full band signals recorded with a high bias current is reproduced. In such a way, it is possible to extract the high frequency signal with a sufficiently high level compared with a conventional case where the relationship is ignored between the frequency of a sound signal and the bias current.

Title: Control method of fuel cell power generation device
Inventor: NAGASAWA MAKOTO
IPC: H01M8/00
Filed: 1989-05-24
Abstract: PURPOSE:To prevent a drop of the secondary battery voltage owing to a load variation by adding a charging power correcting value computed from the cell voltage integrated value to a secondary battery charging power value computed from a power to feed to the load. CONSTITUTION:The charging power value to charge a secondary battery is computed depending on a power to feed to the load. Then a battery voltage integrating device 20 integrates the battery voltage for a specific time, the resultant value is input to the first and the second comparators 21 and 22, and it is compared with first prescript value determined by the property and the capacity of the cell and with the second prescript value larger than the first prescript value, respectively. And when the integrated value is smaller than the first prescript value, a correcting value P1 is output, and when it is larger than the second prescript value, a correcting value -P2 is output. After that, the correcting value P1 or -P2 is added to the charging power value to carry out the correction. Consequently, even when a load variation is generated continuously for a long time, a drop of the secondary battery voltage can be prevented, and the deterioration of the battery capacity can be reduced.
