Title: Air-conditioning equipment
Inventor: TANAKA TOSHIMASA
IPC: F24F11/02
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To actually feed an electrical charge or the amount of power consumption and to enable a user to easily achieve an energy-saving target by providing an automatic operation stop mode for stopping operation automatically when either the electrical charge or the amount of power consumption being set in advance is reached when home air-conditioning equipment is operated. SOLUTION: When an automatic operation stop mode is selected, an operation/stop button 3 of a remote controller 1 is pressed. Then, when an indoor machine 5 receives an operation signal with an automatic operation stop signal, it starts operating air-conditioning equipment. The calculation of an electric charge is initialized simultaneously with the operation start, an electric energy is integrated by a consumption current value and is converted to the electric charge by a preset power charge. In this case, most of it is the electric energy of an outdoor machine 6 and represents the total electric energy of the air- conditioning equipment, but the electric energy of the indoor machine 5 also needs to be added for improved accuracy. An operation continues as far as the converted electric charge does not exceed the preset electric charge.  However, when the set electric charge is exceeded, the operation of the air- conditioning equipment is automatically stopped.

Filed: 1985-03-28
Abstract: PURPOSE:To measure displacement with high precision by projecting laser beam upon a plane mirror and separating the laser beam spectrally into the 1st laser beam and the 2nd laser beam which is branched from it. CONSTITUTION:When a laser oscillator 2 oscillates to emit laser beam 1, the laser beam is separated spectrally by a half-mirror 5 into laser beams 3 and 4. One beam 4 causes the projection of laser beam 7a as shown by an arrow 8. The other beam 3 is transmitted through the half-mirror 5 to generate laser beam 17, which is passed through a polarizing plate 10 to reciprocate between the plane mirror 16 and a right-angled mirror 18 plural times as shown by an arrow 26. Then, the beam 17 passes through the 2nd lambda/4 plate 20 in the middle of the 7th movement to generate laser beam 19, which is joined with the beam 7a at the projection point of the half-mirror 22 to generate interference laser 21, which is photodetected by a detector 23. The body whose displacement is to be measured is displaced finely as shown by an arrow 27. Then, there is specific variation in the difference between optical paths before and after the displacement. Then, an arithmetic processing part 24 calculates the quantity of displacement automatically on the basis of an electrical signal outputted by the detector 23.

Abstract: PURPOSE:To facilitate the fault simulation which reflects device structures and process defects by subjecting the fault samples extracted randomly at the frequency corresponding to the degeneration fault incidence probability of gate levels to simulation. CONSTITUTION:The probability of the incidence of the 0-degeneration fault of the output node of an inverter circuit is designated as P0 at the time of shorting of an n-type transistor. The probability of the incidence of the 1-degeneration fault is designated as P1 at the time of shorting of a p-type transistor. The 0-degeneration fault incidence probability of the output node in a 2-input NOR circuit is 2P0 in probability at which one of 2 pieces of the n-type transistors shorts and the 1-degeneration fault incidence probability is P1<2> in probability at which both the two p-type transistors short. Further, the 0-degeneration fault incidence probability of the output node in a 2-input NAND circuit is P0<2>, and the 1-degeneration fault incidence probability is 2P1. The faults are grouped in order of the magnitudes of the fault incidence probabilities calculated in such a manner. The faults are extracted at the frequencies corresponding to said fault incidence probability by each of the groups at the time of sampling the faults randomly.

Title: Water level regulation valve
Inventor: IWASAKI MASAHIRO
IPC: F16K31/26
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To eliminate a water hammer and miniaturize and reduce the cost. SOLUTION: In this valve, a cylindrical valve element 17 is provided slidably on the same shaft in a cylindrical valve casing and the valve is closed by sticking the valve element 17 to a valve seat 18. At this valve closing time, the downstream side end surface of the valve element 17 is enlarged than the same upperstream side end surface. Thereby, the force to a close direction is offset by the force to an open direction and the water hammer is prevented. Meantime, when the inner surface of the downstream side end is formed in a slant surface, the water pressure from a perpendicular surface is easy to receive and the force of the open direction is exerted surely. When the inner surface of the upperstream side is formed in the slant surface, the water flow pressure acting to the end surface is reduced and the water hammer phenomenon can be reduced further.

Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To improve the relief efficiency of a dynamic type RAM or the like having a refresh mode and a defective relief function by a redundant word line, and to increase the yield of the product. SOLUTION: In a dynamic type RAM or the like, a bit for a refresh switching control signal is added as the most significant bit of a refresh address counter RCTR, that is, a refresh address signal Ri+1 for successively designating word lines W0-Wm to be refreshed of a memory array MARY. When the refresh switching control signal is a low level, only a refresh operation related with the redundant word line WR of a redundant memory array RARY is executed, and when the refresh switching control signal is a high level, the refresh operation related with word lines W0-Wm and the redundant word line WR is executed. Thus, the refresh operation related with the redundant word line WR can be executed in a cycle which is, for example, 1/2 times as long as that of the refresh operation related with the normal word lines W0-Wm.

Abstract: PURPOSE:To enable the efficient exposure of water to be treated to a magnetic field, by providing plate magnetic poles of opposite polarities adjacently to each other through a spacer comprising a nonmagnetic material at both sides of the flat surface of a nonmagnetic pipe line along the flowing direction of water to be treated. CONSTITUTION:Water to be treated flows through connecting metal fitting 1 into a pipe line 5 and crosses lines of magnetic induction from magnets 6 having opposite poles faced to each other attached to the outside of the pipe 5 with an approximately right angle. In addition, the magnets 6 are arranged in a manner such that their polarities are alternatively changed along the flowing direction of water, so that magnetic flux crosses the pipe line 5 while alternatively changing its direction. Hence, the water to be treated is uniformly and sufficiently exposed to the magnetic flux. Since the widthwise size of the pipe line 5 is made equal to that of the magnets 6, uniform magnetic flux is formed at any part of the interior of the pipe line 5. In addition, since a sufficient space is provided between the inner wall of an outer tube 2 and the magnets 6, the release of the magnetic flux from the magnets 6 outside the pipe line 5 is eliminated.
