Title: Driving method for phase-transition type liquid-crystal display unit
Inventor: TAGUCHI MASAAKI
IPC: G09G3/18
Filed: 1978-05-30
Abstract: PURPOSE: To make it possible to apply a phase-transition type liquid-crystal display unit for an electronic desk calculator, wrist watch, etc., by reducing its power consumption by making a voltage applied for maintaining display lower than an impressed voltage at the time of the display.  
     CONSTITUTION: To carry out display by using a mixed liquid crystal of a P-type nematic liquid crystal and a cholesteric liquid crystal or chiral nematic liquid crystal and by utilizing the phase transition between a focal conic state (F state) and a transparent nematic state (N state), a high voltage is applied in order to obtain rapid response of display (erasing or write) from the F state to the N state, thereby obtaining the transparent state. Then, a lower voltage but is above a transition voltage from the N state to the F state is applied, thereby maintaining a transparent erasing or writing state. In this method, the power consumption can be lessened in comparison with continuous application of a high voltage, applied at the initial state, even for maintaining the display.

Title: Microprogram control system
Inventor: NORO TERUO
IPC: G06F9/28
Filed: 1982-04-21
Abstract: PURPOSE:To obtain another independent microprogram (muP) control part with just an addition, by switching the address of a bank which has no relation with the reading of the next instruction and then reading a muP of a different type. CONSTITUTION:An instruction reading register 103 is usually read out at the side 102 of a bank 0 of a muP storing memory, and the reading at the side 112 of a bank 1 is carried out only with a condition branching instruction. The side 112 is not used through an instruction executing part 104 for instructions other than the condition branching instruction. Therefore a muP address register 201 is selected as a muP address of the side of the bank 1, and a subordinate muP is fetched to an instruction reading register 203 and executed at a subordinate instruction executing part 204. While in case the reading instruction of the main register 103 is equal to a condition branching instruction, the corresponding instruction decoding signal 210 sets a muP address selection bit 205 at 0 and selects the output of a muP address register 101 as a muP address of the side of the bank 1.

Title: Memory management system
Inventor: OHASHI NORIO
IPC: G06F12/02
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To accept the synchronous processing such as an interrupt, etc., and to always perform the acquisition/release processing even in a synchronous processing mode by preserving the processing situation right before the acquisition/release processing, restoring the preserved processing situation against the report of an exception, and then executing again the acquisition/ release processing. SOLUTION: The processing situation obtained before the acquisition/release processing is preserved when the acquisition/release processing of a memory is started in a process A (101). When the asynchronous processing like an interrupt, etc., occurs during the memory acquisition/release processing of the process A and then this acquisition/release processing is executed (103), the process A discriminates whether the memory acquisition/release processing is presently executed or not (104). If this processing is executed, the occurrence of the exception processing is notified to the said processing (105). In an exception processing mode, the preserved situation is restored (107) and the memory acquisition/ release processing is started.
