Title: Disc cash write-in control system
Inventor: TOKUNAGA TAKEHISA
IPC: G06F3/00
Filed: 1979-05-25
Abstract: PURPOSE: To simplify the cash control and to reduce the write-in time to disc, by avoiding the record on disc for the part written in the cash memory among the data of temporary file.  
     CONSTITUTION: When readout instruction is output with a temporary file mode, if the addressed sector is present in the cash memory 500, required sector is read out from the cash block and given to CPU to complete the input and output operation. If not, the disc cash control unit 400 reads out the sector from the disc and delivers it to CPU via the data buses 570 and 560. In this case, no renewal of the cash memory 500 is made. Then, the block is assigned to the cash memory 500 at the data write-in and only the blocks not assigned are written on the disc. This assignment is fixed during the file usage period.

Title: Method for assigning storage device
Inventor: MAAKU EFU RESUMAN
IPC: G06F9/50
Filed: 1994-03-09
Abstract: PURPOSE: To provide an adapting method for allocating a RAM to a procedure having different procedure. CONSTITUTION: A RAM is equipped with a 1st part which is assigned to a procedure of high priority and a 2nd part which is assigned to a procedure of low priority. This invented method includes several stages. Namely, it is decided whether or not the RAM of the 1st part is usable in response to a request for allocating the RAM to the procedure of high priority and when not the RAM from the 2nd part is assigned to the procedure of high priority. When the RAM which is usable from the 1st part exceeds a 1st threshold level, the RAM from the 2nd part can be assigned to the procedure of low priority. A system continues the allocatable state until the RAM usable from the 1st part decreases below a 2nd lower threshold level, and when the RAM decreases below the level, allocation to the procedure of low priority is inhibited.

Title: Interface of cpu
Inventor: OOTANI MASAHIRO
IPC: G06F15/17
Filed: 1982-04-20
Abstract: PURPOSE:To assure the transfer of data, by providing a logical circuit which delivers a wait ready signal in response to the write/read signal supplied from a CPU as well as a temporary storage element which stores data temporarily. CONSTITUTION:An interface contains octal latches 5 and 6 which store temporarily data of plural bits and a logical circuit which fetches read/write signals from CPU10 and 20 and then delivers a wait/ready signal in response said write/ read signal. When the data of 1 byte is written to the latches 5 and 6 from one of CPU10 and 20, the wait signal is sent back to the corresponding CPU from the interface synchronously with the writing of the data of 1 byte. This prevents that the next data is written before the above-mentioned written data is read by a CPU of the other side. At the same time, the interface delivers both interruption and ready signals to the CPU which reads the data.

CONSTITUTION:The plastic film 12 of the 1st electrode substrate 1 sandwiching a polarizing film 11 has the coefft. of expansion larger than the coefft. of expansion of a lower film 13 and therefore if said substrate is adhered to the 2nd electrode glass substrate 7 by an adhesive layer 14 at a high temp. and is allowed to cool to a room temp., the outside thereof is going to curve on the side opposite from a liquid crystal layer 6 but since the glass substrate 7 is hardly curved by an environmental change, the substrate 1 is held by spacers 5 and is thus prevented from deforming. The 3rd electrode substrate 2 is constituted of a polarizing film 21, plastic films 22, 23, the spacers 5 and the layer 6 in the same manner as with the substrate 1 and even if the substrate is going to curve into a recessed shape on the side opposite from the layer 6, the substrate 2 is held by spacers 5 and is prevented from deforming. The laminated two layers 6 are thus made respectively uniform.
