Title: Cmi encoding circuit
Inventor: ARAI MASANORI
IPC: H03M5/04
Filed: 1984-02-24
Abstract: PURPOSE:To output a CMI code having no whisker-like pulse without multiplying a clock by two, by adding the third flip-flop, and constituting a titled circuit so that the whisker-like pulse is eliminated thereby. CONSTITUTION:A data (a) and a clock (b) are inputted to an input terminal IN and a clock terminal CLK, respectively. An output signal f' of the second flip- flop FF2 goes to a signal which has frequency-divided ''1'' of the data (a), and the output signal (g) of a gate circuit G8 goes to a signal which is delayed the data (a). The output signal h' of a gate circuit G10 goes to an NAND logical output of the signals f', (g), and sometimes a whisker-like pulse is generated in h' due to the variation of a delay time of each element, but to a clock terminal C of the third flip-flop FF3, a delayed signal (o) is supplied through gate circuits G1, G3, G4, G17 and G18, the FF3 reads a data thereby, therefore, the whsiker- like pulse is eliminated and read in the FF3. An output signal (n) of a gate circuit G20 is formed when the data (a) is ''0'', and reduced to a set signal, and the output signal (p) of the FF3 becomes a CMI code.

Title: Prestaging system of mass storage in virtual computer system
Inventor: OONO HITOSHI
IPC: G06F12/08
Filed: 1982-03-02
Abstract: PURPOSE:To access quickly data existing in a mass storage, by allowing a virtual computer to prestage a data on the mass storage into a mass storage device on a basis of the private operating control. CONSTITUTION:When a virtual computer B12 uses a virtual volume, the computer B12 issues a mount request to a control program OS operated on the computer B12. The mount request is converted to a mount order to a mass storage controller 13 by the OS and is issued as an I/O request. When receiving the mount order, the controller 13 stages only the region of a requested cylinder to a mass storage device DASD 17 controlled by a staging controller SDC 14. Though a mass storage facility MSF 16 moves a cartridge to a data recording mechanism each time the stage processing is performed, the OS prestages the region, which is judged to be necessary, on the mount-requested virtual volume. Thus, the access time is shortened.

Title: Recorder with cooling part
Inventor: SATO TAKUMI
IPC: G03G15/20
Filed: 1985-02-20
Abstract: PURPOSE:To keep a heat roll at a temperature required for toner fixing and to prevent a heat source and a cooling fan from consuming excess power, by turning on and off a cooling fan motor power source provided near the heat source for fixing by a control signal of a power supply part which turns on and off the heat source for fixing. CONSTITUTION:When the heat source is turned on, the temperature of a heat roll 11 rises gradually, and the heat source is turned off when this temperature reaches the upper limit of a set temperature. The turning-off signal of the heat source is used as a trigger to operate a cooling fan 14, and the heat roll 11 is cooled for a set time set preliminarily by a timer. Though the surface temperature of the heat roll 11 having a large heat capacity will continue to rise after the heat source is turned off, the surface temperature of the heat roll 11 is saturated ad falls when it is slightly higher than the upper limit temperature because the cooling fan 14 starts to cool the heat roll, and the surface temperature enters into the set temperature. Thus, turning-on and off of the heat source and the cooling fan 14 are synchronized by the control signal to hold the fixing temperature of the heat roll 11 in the good state, and unnecessary power consumption is prevented.
