Title: Counter device
Inventor: TAMURA TOSHINORI
IPC: G06F9/48
Filed: 1986-05-14
Abstract: PURPOSE:To reduce the number of bits in a hardware counter without using an overhead by taking an area in a data memory for the count value storage area in a host side counter so as to use it and giving a microservice function. CONSTITUTION:First, and I/O request control part 205 reads out data in a software counter 103-1, increments the read-out data, and stores it in the counter 103-1 again. A series of processings completes the increment of data on the software counter and its transfer processing. Whenever the hardware counter 105 overflows, said microservice is repeated. Detecting the occurrence of the overflow from the counter 103-1, an I/O request acceptance part 206 activates an interruption processing program, and executes the same interruption processing as when a conventional bit counter overflows.

Title: Encoding circuit
Inventor: YONEDA MASATO
IPC: G11C11/413
Filed: 1992-04-30
Abstract: PURPOSE:To share a memory even when the number of bit of an input signal is different by providing a don't care circuit and masking the inputted signal from an input line at every bit as necessary. CONSTITUTION:The input signals a0, a1 are inputted to an AND gate through an OR gate forming the don't care circuit as it is or inverted. Don't care signals A0, A1, as well are inputted to the OR gate and when the signals A0, A1, are a logic level (0) also, the signals a0, a1 are inputted to the AND gate as it is or inverted. Further, when the logic level of the signal A1 is (1), the signal a1 is ignored and the signal a0 or the inversion signal a0' is outputted. On the other hand, when the logic level of the signal A0 is (1), the signal a0 is ignored and the signal a1 or the inversion signal a1' is outputted. Further, the signals A0, A1 are the logic level (1) also, all the signal a0, a1 are ignored. In such a manner, since the optional output is obtained at the logic level of the don't care signal even when the number of bit of the input signal is different, the memory is shared.

Title: Gas-insulated stationary induction electric apparatus
Inventor: KOJIMA TAKESHI
IPC: H01F27/12
Filed: 1984-06-04
Abstract: PURPOSE:To enhance the cooling effect and enable a reduction in size of a gas-insulated stationary induction electric appartus, by employing a hollow conductor as a winding accommodated in a tank together with an insulating gas, and forcing an insulative cooling medium such as an insulating gas to circulate through the inside of this hollow conductor, thereby cooling the winding. CONSTITUTION:A cooling medium is forced by a pump 7 to circulate through a hollow part 10 of a winding 4 as shown by the illustrated arrows, whereby the heat generated in the winding 4 is absorbed by the cooling medium flowing while directly contacting the winding 4, and the cooling medium flows into a cooler 6. The warmed cooling medium is cooled down by the cooler 6 and flows through the hollow part 10 of the winding 4 again. The winding 4 is cooled by the repetition of this operation. Employment of an insulative liquid as this cooling medium particularly enhances the cooling effect. Although the pump 7 needs a relatively high pressure for forcing the cooling medium to circulate through the hollow part 10 of the winding 4, smooth circulation is allowed by appropriately selecting the size and number of pipes 11a, 11b, and appropriately changing the length of the winding 4 by which the cooling medium passes therethrough.

Title: Image forming device
Inventor: HAYAKAWA NAOSHI
IPC: G03G21/10
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent a cleaning blade from being vibrated and producing abnormal sound when a photoreceptor is stopped by setting the abutting pressure of the cleaning blade to the photoreceptor in a specified range when toner remained after transfer is removed and lowering the abutting pressure to the specified range when the photoreceptor is started to be decelerated. SOLUTION: Switching control is performed so that the abutting pressure of the cleaning blade 14 to the photoreceptor 1 may be 15 gf/cm to 30 gf/cm when the blade 14 removes the toner remained after transfer on the photoreceptor 1 and it may be 3 gf/cm to 7 gf/cm when the photoreceptor 1 is started to be decelerated. Namely, at the time of removing the toner remained after transfer on the surface of the photoreceptor 1, the abutting pressure of the blade 14 to the surface of the photoreceptor 1 is increased to prevent cleaning performance from being deteriorated. When image forming operation is finished and the photoreceptor 1 is decelerated, the abutting power of the blade 14 to the surface thereof is weakened to prevent the blade from squeaking before stopping.
