Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To know the outline of entire received image data stored in a memory, even in the state of less residual capacity in a battery by performing the digest print of stored image data in the memory through a printer. SOLUTION: Based on the detected contents of a voltage detecting part 231, a battery monitor part 23 decides whether the residual capacity of a battery 21 is more or less. The voltage detecting part 231 compares the terminal voltage of a secondary battery 22 with a reference value, and this compared result it sent as data for decision by the battery monitor part 23. When the residual capacity of the battery detected by the battery monitor part 23 becomes less than a prescribed value, a printing control part 25 lets a printer 16 perform the digest print of stored image data in an image memory 14. In the case of digest print, the image data stored in the image memory 14 are printed out, while being limited for the prescribed number of lines for each page.  The contents of received image data stored in the image memory can be known at most, without waiting for the charging end of the battery of which the residual capacity become less.

Inventor: ASANO TAKASHI
IPC: F16K31/06
Filed: 1984-09-28
Abstract: PURPOSE:To provide a small and cheap system without any relay by providing a switching valve opening at the non-pressure dropping time in a main feed line and an electric switching valve closing at the non-pressure dropping time in an auxiliary feed line. CONSTITUTION:A pressure switch 8 is opened by the gas pressure of a main gas container 1 and therefore when an electromagnetic valve is used for a switching valve 9, it is not excited, therefore the gas is supplied through a main feed line 2 and gas pressure regulator 6 to a demand part 7. When the gas pressure drops, because the pressure switch 8 is closed and the switching valve 9 is also blocked, the gas feed from the main feed line 2 is suspended. At the same time, the current is applied to the electric switching valve 10 of an auxiliary feed line 4, thereby the feed line becomes the open condition. The gas feed system thereby is switched to the auxiliary gas feed line starting from an auxiliary gas container 3 to the auxiliary feed line 2.

Abstract: PURPOSE:To reduce the error in conversion, by forming a reference voltage at A/D conversion of lower-order bits based on upper-order bits of a digital output and providing an offset corresponding to the upper-order bits for the reference voltage. CONSTITUTION:A 3-bit parallel A/D converter 11 converts an analog input voltage Vin into digital outputs, upper-order three bits H2-H0 and lower-order three bits L2-L0 in time division. The signals H2-H0 are applied to a latch 15 in three bits and switches 12, 13 are changed over into inverted state as shown in figure. The signals H2-H0 from the latch 15 are applied to a D/A converter 16, where the signals are converted into an analog voltage V16 having a value three times the signals H2-H0 and the analog voltage is applied to the converter 11 through the switch 13 as a reference voltage for lower limit. The voltage V16 is offset by 8V at a DC power supply 17 and applied through the switch circuit 12 as a reference voltage for upper limit for the converter 11. Thus, errors at a joint between the upper-order and the lower-order bits can be eliminated.
