     CONSTITUTION: The heat-pipe-type air coolers A, B are placed at an upper and a lower levels so that the sections (a), (b) of the coolers are overlapped with each other. The heat pipes 6' at the right of partition walls 7, 17 or the heat pipes of a section (b) are wetted by the capillarity of a cloth 12 so that the heat pipes are cooled by the evaporation of water. Therefore, the heat pipes 6" of the section (a) are also cooled. Rotating a fan 20, the heat pipes of the section (d) of the air cooler B are cooled. Because the air cooler B performs the same cooling action as the air cooler A, the heat pipes of the section (d) of the air cooler B are cooled further. As a result, the temperature of a section (c) falls below the wet-bulb temperature.

Title: Automatic analyzer
Inventor: ORIMO RIYOUICHI
IPC: G01N33/48
Filed: 1979-04-14
Abstract: PURPOSE: To improve the precision, reliability and the capacity of the automatic analyzer by a method wherein the lag phase and the linear phase are monitored at many positions on the reaction line, and useful data are taken out from many light-measurement data.  
     CONSTITUTION: A cuvette 4, each injected with a portion of a reagent, is measured by photoelectric colorimeters 12W15, arranged at many places separated by an integer multiple of the amount of movement of one step of the cuvette 4 on reaction line B. Photoelectric colorimeters 12W15 monitor not only lag phase (a) of the curve in the drawing, where the axis of ordinate represents light-absorption degree O.D. and the axis of abscissa represents reaction time t, but also linear phase (b).  That is, the liquid specimen of which the end point of the lag phase is detected by one of photoelectric colorimeters 12W15 is measured by another colorimeter lying behind during the time that the liquid specimen is in the linear phase, and then it is discarded. By this, data of high precision and high reliability analysis can be obtained and at the same time processing capacity can be improved.

Title: Multi-room air conditioner
Inventor: ISHIKAWA YOSHIMASA
IPC: F25B13/00
Filed: 1998-02-26
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal superheating in an indoor heat exchanger even when the load demanded by an indoor unit is varied, while sustaining a correct demand capacity, by varying the indoor fan speed of each indoor unit depending on the variation of indoor load demand during cooling operation. SOLUTION: At first, in an indoor unit 4a, a load demand signal calculated by a temperature difference operating circuit 50 is delivered to an indoor fan operating circuit 51 along with a set fan speed signal from an operating setting circuit 38a. An indoor instability operating circuit 51 determines an indoor fan speed from the load demand signal and the set fan speed signal based on a specified graph and delivers it to an indoor fan drive circuit. Since the indoor fan speed is controlled depending on the fluctuation in the load demand of each room after starting operation, balance can be sustained between heat absorption (indoor fan speed) and refrigerant circulation (opening of motor expansion valve) of an indoor heat exchanger can be sustained and fluctuation in the superheating of refrigerant can be suppressed.

Title: Redundancy circuit
Inventor: URATANI MUNEHIRO
IPC: H01L27/10
Filed: 1984-03-08
Abstract: PURPOSE:To eliminate defects such as the delay of an access time and simultaneous selection of plural circuits due to the delay, and perform signal processing at a high speed by disconnecting a defective circuit through a fuse in the redundancy circuit which substitutes the defective circuit with a normal circuit. CONSTITUTION:Lines W0-WN of memory are connected normally to inverters CINV0-CINVN through fuses F0-FN respectively and the fuse corresponding to defective memory is blown to disconnect the memory from the output of the inverter. If there is a defect in the memory area of the line W1 in this circuit, the fuse F1 is blown by a laser disconnector, etc., during a test of the memory. Further, control based upon a signal -DSEL like a conventional circuit is not performed, so response speed of -SW0'--SW1', and -W0'--WN' to address signals are nearly equal, so the loss due to the delay of access is eliminated.

Abstract: PURPOSE:To enhance a secondary combustion ratio and to increase the compounding ratio of scrap by specifying the height position of a lance nozzle having main holes and auxiliary holes and specifying the angle of the oxygen jet to be flown through the auxiliary holes and the oxygen flow rate ratio thereof. CONSTITUTION:Converter refining is executed by using the lance nozzle 1 having the main holes 2 (about >=3 holes) and the auxiliary holes (about >=4 holes), blowing the oxygen for refining through the main holes 2 and the oxygen for secondary combustion through the auxiliary holes 3 and burning the gaseous CO generated in the furnace.

Title: Electrophotographic device
Inventor: TANIZAKI JUNICHI
IPC: G03G21/00
Filed: 1987-02-27
Abstract: PURPOSE:To decrease the spread of light by reflection in a dustproof member and to permit efficient electric charge by curving the dustproof member so as to crown toward a photosensitive member. CONSTITUTION:This device has the dustproof member 20 having the arc-shaped section around a light emitting source of a light emitting diode 18 and, therefore, the respective parts of the dustproof member 20 intersect orthogonally with the light generated from a destaticizer 16. The refraction is thereby prevented even if the light passes the dustproof member 20. The light is projected at the angle more perpendicularly by the photosensitive member 1 as compared to the case in which the flat surface-shaped dustproof member is used. Spreading of the light is thus obviated. The light eventually repeats reflections at small incident angles on the rear surface of the member 1, the inside wall of a casing 12, a grid plate 7a, etc., and the intensity of the light is thereby weakened before the light arrives at an electric charger 7; therefore, the electric charge operation is not hindered and the charger 7 is capable of making the efficient charge operation.

Title: Driver and apparatus employing it
Inventor: SEKI HIROYUKI
IPC: H02N2/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a drive apparatus from being locked during operation by indicating decrement of the residual lifetime of a vibratory driving means resulted from deterioration thereof or abnormality of a driven means before the function is stopped. SOLUTION: An r.p.m. measuring unit 54 calculates the r.p.m. N of a motor, based on a signal from an encoder 33. A voltmeter 55 measures a signal voltage Vs from a sensor phase S. When a decision is made that the r.p.m. N of a motor exceeds a specified r.p.m. N1, a decision section 56 operates the value of N/Vs. When the lifetime of a motor M is not yet expired, a lifetime prediction means predicts the residual lifetime of the motor based on the operated value of N/Vs and displays the results on a display panel. Since deterioration of the entire drive system can be notified in the early stage to a user and the drive system can be maintained before the lifetime of the motor expires, failure can be prevented during operation.
