Title: Operation control circuit of refrigerator having high-efficiency multi-evaporator cycle(h.m.cycle) and operation control method thereof
Inventor: JO KUNIMASA
IPC: F25D17/06
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To enable a freezing chamber and a refrigerator chamber to be controlled independently for their temperatures by a method, wherein a first fan mounted at the freezing chamber and a second fan mounted at the refrigerator chamber are selectively operated. SOLUTION: At a microcomputer 50, a freezing chamber temperature detected by a freezing chamber temperature sensor 34 is compared with a refrigerator chamber set temperature preset by a refrigerator chamber temperature adjusting machine 33. In this case, when the refrigerator chamber temperature is higher than the freezing chamber set temperature, the freezing chamber temperature is compared with the freezing chamber preset temperature. When the freezing chamber temperature is higher than the set temperature of the freezing chamber, a first fan 22 is turned on, and a second fan 32 is turned off together with a compressor 41. When the freezing chamber temperature is lower than the set temperature of the freezing chamber, the second fan 32 is turned, on and the first fan 22 is turned off together with the compressor 41.  Accordingly, the first fan 22 and the second fan 32 become selectively operated. When the temperature of the refrigerator chamber is lower than the set temperature of the refrigerator chamber, all the operations of the compressor 41, the first fan 22 and the second fan 32 are stopped.

IPC: G11B11/10
Filed: 1989-11-13
Abstract: PURPOSE:To improve the rewrite speed by impressing an initialization magnetic field of >=1 kilooersted from the outside of a case by a permanent magnet for the purpose of initialization and impressing a recording magnetic field of <=1 kilooersted on a disk by leakage flux. CONSTITUTION:The initialization magnetic field 7 is impressed on a recording area by the permanent magnet 5, specifying the magnetic field 7 as intensity of >=1 kilooersted. The magnet 5 is disposed on one side of the case 1, and is supported by a frame 6 made of magnetic substance. A focus actuator consists of an objective lens 10, a driving coil 11 and a permanent magnet 12, where the leakage flux 14 is formed by the magnet 12. Since this focus actuator is of a moving magnet type, the distance between the lens 10 and a magneto- optical disk 3 is kept constant. As a result, the recording medium surface is always impressed with a constant magnetic field, and its intensity is specified as <=1 kilooersted. By this method, the overwrite of a data is feasible.

Title: Congestion control system
Inventor: SOMA NAOKO
IPC: H04Q3/545
Filed: 1990-10-31
Abstract: PURPOSE:To relieve congestion without stopping transmission of a new call by arranging two information storage modules connected to a bus in pair and revising a destination of storage information to other destination when one of the module reaches congestion. CONSTITUTION:When an information module 31 reaches a congestion state, the module 31 sets a largest information quantity among newest information quantity relating to communication control modules 21,22 and sends the result to a module 32. The module 32 compares a newest processing margin with the sent information quantity and sets 'NG' when the margin is smaller and sets 'OK' when the margin is larger and returns the discrimination information to the module 31. When the 'NG' is set, similar processing is implemented to a 2nd largest information quantity corresponding to the modules 21, 22. When 'OK' is set, the module 31 commands it to the module 32 that the destination of the storage information is revised to the module 32. Since the storage information of only one of the modules 21, 22 is fed to the module 31, the congestion state of the module 31 is relieved.

Title: Two-color image forming method
Inventor: OKA KENJU
IPC: G03G15/01
Filed: 1988-11-22
Abstract: PURPOSE:To widen the allowable width of the selection of toner and to facilitate the removal of contaminated toner by making the surface potential of a toner separating body lower than developing bias voltage in a 2nd developing device so that 2nd toner does not adhere to the toner separating body but the 1st contaminated toner adheres to the toner separating body. CONSTITUTION:A photosensitive drum 10 is formed so that it becomes longer than the maximum width of a formed image W1 by a specified width W2 and its extended part 102 is used as the toner separating body. As to the voltage necessary for starting development, the voltage applied on the 1st toner is lower than that on the 2nd toner, and toner which is electrostatically charged so that the 1st and the 2nd toner may have the same polarity when the 1st toner contaminates the 2nd developing device 16 is used in the title method. The surface potential of the toner separating body is controlled to be lower than the developing bias voltage in the 2nd developing device 16 so that the 2nd toner does not adhere to the toner separating body 102 but the 1st contaminated toner adheres to the toner separating body 102 during development by means of the 2nd developing device 16. Thus, the 1st contaminated toner is selectively separated and adheres to the toner separating body 102, thereby accomplishing the collection and the removal of the contaminated toner.

IPC: F01L3/08
Filed: 1997-10-28
Abstract: PROBLEM TO BE SOLVED: To obtain an Fe-base sintered alloy with high wear resistance at a low cost by means of a sintering stage alone by specifying respective contents of Cr, V, C, Mo, and B. SOLUTION: This alloy has a composition consisting of, by weight ratio, 4-14% Cr, 2-6% V, 1.3-2% C, 0.3-2% Mo, 0.05-0.1% B, and the balance Fe with inevitable impurities. It is preferable to incorporate 0.5-2% Si for the improvement of high temp. oxidation resistance, 0.5-2% of one kind among CaF2 , BaF2 , and MOF2 or a mixture of two or more of them for the improvement of self- lubricity and machinability, 1-3% Ni for the improvement of the strength and wear resistance of the alloy to a greater extent, and 0.1-2% Nb for the improvement of the wear resistance of the alloy to a greater extent. Because Co is not contained in the composition, raw material costs can be reduced. Further, manufacturing costs can be remarkably reduced because the wear resistance and mechanical strength of a valve seat, etc., can be improved by means of a minimal stage of sintering alone.
