Title: Phosphating solution
Inventor: NAKAGAWA HIROYOSHI
IPC: C23C22/14
Filed: 1981-08-10
Abstract: PURPOSE:To reduce the rate of sludge formation by adding perchlorate to a phosphating soln. for ferrous materials. CONSTITUTION:Perchlorate is added as ClO4<-> at 0.005-20g/l (more particularly 0.05-5g/l) to a phosphating soln. for forming crystallizable phosphate films on the surfaces of ferrous materials. It is more preferable to control the Zn/PO4 weight ratio in the soln. at 0.2-1, and NO3/PO4 weight ratio at 0.3-3. If such soln. is used, the Fe in the surfaces of the ferrous materials dissolve into the soln. and forms Fe(H2PO4)2 which deposits much on the surfaces of the ferrous materials, thereby accelerating the growth of FeZn2(PO4)2.4H2O. The eluted Fe<2+> contributes largely to film formation and reduces the formation of sludge owing to oxidation of Fe<2+> Fe<3+>.

Abstract: PURPOSE:To prevent a battery from being completely discharged. by providing a device for starting and stopping a power generator when a power supply is turned on and off by means of a power source switch, and a vehicle controller for lowering a working bed when a signal vanishes since power supply to the working bed and the controller is cut off. CONSTITUTION:A circuit is established so that a stopping device 4 incorporated in a power generator 3 is energized by using a power source switch 7 for a working bed side controller 8. A worker riding on the working bed 2 turns on the power source switch 7 so as to start the power generator 3, and upon completion of a work, he turns off the switch 7 so as to stop the operation of the controller 8 and simultaneously stop the power generator 3. A vehicle side controller 13 receives a signal from the working bed side controller 8 through an optical fiber 14 so as to examine the content of the signal so as to determine one of operations such as advancing, backing and stopping of a vehicle 1, and ascending and descending of the working bed 2. When the power source switch 7 is turned off so that the signal vanishes, the vehicle side controller 13 determines that the work has been completed, and accordingly, lowers the working bed 2.

IPC: G11B20/12
Filed: 1994-05-17
Abstract: PURPOSE:To prevent data access time from becoming long and large by deciding the number of remaining alternate sectors of the alternate sector area of a group to which a specified recording sector is belonging and deciding whether a data recording commanded from a host device can be accepted or not according to the number of remaining alternate sectors. CONSTITUTION:A host device sets an alternation prohibition possible mode with respect to a magneto-optical disk device via a host I/F 6. The control part 2 of the magneto-optical device reads in the defection managing information of a magneto-optical disk 1 in an initialization procession to prepare a table of numbers of defective sectors for respective groups and preserves the table in the memory for control 5. When a data recording is commanded, the control part 2 calculates the number of remaining alternate sectors of the group to which a specified sector is belonging by referring to the content of the table and in the case the number of the remaining alternate sectors is zero, the control part 2 allows it to be completed as an error. Thus, since data are recorded in a form in which sector alternate processions are finished in the same group, a situation in which data access time is prolonged is avoided.

The entire surface of the liquid crystal is thereafter scanned and the desired patterns are displayed by repeating the similar operations. Since the prescribed time is provided after the impression of the erasing voltage before the start of the impression of the writing voltage in such a manner, the stabler writing is enabled and the large-capacity display of a high contrast and high grade is enabled.
