Filed: 1977-11-16
Abstract: PURPOSE: To soon balance this machine even both when the quantities of loads are little and when whey are much, by turning a rotary drum at the number of different revolution every return to balance operation.  
     CONSTITUTION: When a timer 23 is closed while assuming that a change-over switch 41 is closed to the contact 42 side, a 1st motor 12 for balance is driven, and a rotary drum 1 is turned at 40 r.p.m., thus resulting in balance operation. When the quantities of loads are much at that time, loads cannot be lifted by the number of the revolution of 40 r.p.m., abnormal vibration is generated when entering dehydration operation, and a switch 34 of detecting vibration is operated. A relay 25 is excited at that time, a constantly-closed contact 36 is opened and conduction to a motor 7 is broken while changing over the change-over switch 41 to the contact 43 side. Consequently, a 2nd motor 18 for balance is driven, the rotary drum is turned at 55 r.p.m., and loads are disentangled even when the quantities of loads are much, thus uniformly distributing loads.

Title: Rolling method for one-side clad sheet material
Inventor: UEHORI YUJI
IPC: B21B1/38
Filed: 1985-06-27
Abstract: PURPOSE:To effectively suppress a sheet camber by using a high-chromium roll for a work roll on the sheet camber side and disposing a high-alloy grain roll to the other work roll. CONSTITUTION:The high-chromium roll having low heat conductivity is used as the upper work roll of a rolling mill for a stainless steel clad sheet material and the high-alloy grain roll having high heat conductivity is disposed to the lower work roll. The heat generated by rolling is made difficultly escapable from the upper roll and eventually the temp. on the top surface side is higher than the lower surface side if the material is rolled with the stainless steel on the upper side. The deformation resistance is lower as the temp. is higher and therefore the difference in the deformation resistance between the top and bottom surfaces is decreased even if the hard stainless steel is on the top surface. As a result, the sheet camber is effectively suppressed by the combination of the rolls consisting of the different materials as shown in the figure.

Abstract: PURPOSE:To prevent the unauthorized readout of a program, by providing a means which compares loading information with previously set information when a loadable program is loaded. CONSTITUTION:When a loadable program A provided with loading information is prepared, the program A is stored in an external storage 3. When the program A is debugged thereafter, loading information indicating the loading level of a debugging program A is given to a register 9.

Title: Abnormality detecting system for access to out-area memory
Inventor: CHIBA YOSHIHIRO
IPC: G06F15/16
Filed: 1984-07-05
Abstract: PURPOSE:To prevent an erroneous access to a common memory by comparing an address with another registered address when accesses are given to the common memory from each processor. CONSTITUTION:The address signal delivered from a processor is supplied to a RAM14. Both use and non-use areas of the processor are registered to a RAM14 in an initialization mode. In case accesses of the processor are abnormal, the RAM14 delivers an RDDE signal when an access is given to a read area of the non-use area and a WTDE signal when an access is given to a write area respectively. Under such conditions, a driver 12 or 13 is not actuated and the *RD and *WT signals to be applied onto a common bus are locked and not delivered. Thus no writing is carried out to the common bus. While a NAND gate 15 or 16 produces an output after the signal RDDE or WTDE is produced. This output is sent to the processor as an *access abnormality signal, and the processor inhibits the use of the read-out data.

The supernatant is then discharged therefrom. The precipitated mud content is sent between scraping-up vanes 112, and as the drum 101 rotates, the water content flows down between an annular end plate 107 and a blind end plate 110. The mud content falls along the scraping-up vanes onto the outside circumferential surface of a circular cone body 111 and is discharged along a guide plate 115 to a sludge discharge pipe 120. Thence, if falls into the inner drum 202 of a dehydrator 2, is sent to an annular end plate by spiral vanes 208, and further rolls in the inner drum 202, where it is separated of water content and agglomerates. Thence, it is lifted by scraping-up vanes 213, slips on a circular cone body 210, whereby it is further separated of water content, after which it is discharged from a sludge discharge hole 207.
