Patent JP-H09269714-A (JP)
Title: Image forming device
Inventor: TERAO MASATO
IPC: G03G21/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve the operability by an operator without lowering an energy- saving effect by measuring the operation frequency of a device and deciding a time taken until interrupting a power source based on a measured result. SOLUTION: A buffer equivalent to a present time secured at the inside of an NVRAM 16 is selected. For instance, the number of times of copying operation performed in an hour from 4pm to 5pm is stored at a 4pm buffer. A value stored in a selected buffer is substituted to a counter, so that an automatic shut-off time is set. The time taken until interrupting the power source by automatic shut-off is set short as the use frequency of a copying machine at a time zone is small. In the case that copying is started after substituting zero to the counter, the value of the counter is increased by one. When the time zone is changed, a present counter value is stored in a present buffer, and the buffer is newly selected.

Title: Radiator of high efficiency
Inventor: NAKAMATSU YOSHIRO
IPC: F24D7/00
Filed: 1986-04-05
Abstract: PURPOSE:To make a base board compact, to prevent a radiating element from overheating, and to increase the radiation cooling effect, by laying radiating elements on top of the other to make a multi layer, and by composing the layer by pinching the radiating element on the high temperature side between a radiating board and the element on the low temperature side. CONSTITUTION:The whole length of a radiating pipe 5 is made '2L', double the conventional length 'L'. It is laid and fixed on a based board by bands 9. When a heating medium is passed through the pipe 5, the heat is gradually lowered by radiating of heat. When the heating medium is routed through the doubly laid pipe 5, the stage from which the heating medium is fed becomes a radiating element 10 on the high temperature side, while the side from which the heating medium is discharged acts as an element 11 on the low temperature side. The one in which the element 10 on the high temperature side is pinched between the base board 7 and the element on the low temperature side is more radiative and has larger cooling effect than the one in which the element 11 on the low temperature side is pinched between the base board 7 and the radiating element 10 on the high temperature side.

Abstract: PURPOSE:To obtain a full subtracter which is optimum for constituting a subtracter and divider of a higher speed, by using a CMOS composite gate, and decreasing the number of logical gate stages generated by a delay time. CONSTITUTION:When input signals A, B, and Ci are simultaneously inputted, the signals A, B, and Ci are simultaneously obtained by inverters 5, 6 and 7, respectively. Also, six signals A, B, Ci, the inverse of A, the inverse of B and the inverse of Ci are inputted to logical gates 1-4, therefore, a difference output signal D is obtained by a delay time of two stages of gates, of one stage of the inverter and one stage of the logical gate (1 or 2). Moreover, a borrow output signal Co is also obtained in the same way by a delay time of two stages of gates, of one stage of the inverter and one stage of the logical gate (3 or 4). Accordingly, the delay time of a full subtracter is shortened to about 1/2.5 of a conventional time, together with the difference output signal D, and the borrow output signal Co.
