Title: Method for charging refrigerant
Inventor: OE TAKAHITO
IPC: F25B49/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive method for charging refrigerant. SOLUTION: An empty tank 14 is connected with a valve 10 provided in a high pressure pipe 8A of a refrigeration cycle 1 and a refrigerant compressor 2 is driven to fill a gas refrigerant into a low pressure part of the refrigeration cycle 1. The tank 14 has a capacity large enough to store a refrigerant of an amount corresponding to a predetermined degree of supercooling. After checking, through a sight glass, that bubbles have been broken, charging of the refrigerant is suspended. At that moment, the tank 14 connected to the pipe 8A is filled with the liquid refrigerant having a degree of supercooling of 0 degree. After charging the refrigerant, if the compressor 2 is stopped, a part of the refrigerant flows to the low pressure part of the cycle 1 so that the pressure in the cycle 1 falls, and hence the refrigerant in the tank 14 flows into the cycle 1 under gravitation. After the refrigerant in the tank 14 has completely flowed into the cycle 1, the tank 14 is removed and the charging of refrigerant is completed.

Title: Television camera
Inventor: TAKANO MITSUO
IPC: H04N5/335
Filed: 1981-05-27
Abstract: PURPOSE:To suppress the blooming phenomenon which is caused to an image pickup matter for video signal, by providing an image pickup body for detection of a highlight and controlling the light transmission factor of a liquid crystal matrix based on the result of the highlight detection. CONSTITUTION:The greater part of the incident beam given through a lens 1 is made incident to the 1st image pickup body 3 through a half mirror 2 and via a liquid crystal matrix 5. The rest of the incident beam is made incident to the 2nd image pickup body 4 in the same way. The signal supplied from the body 4 is applied to a binary coding circuit 9 via a sample holding circuit 6, a low pass filter 7 and an amplifier 8 and then sliced at a level equivalent to the saturated charging degree of the body 3. This sliced signal is binary coded and stored in a shift register 10. A driving circuit 11 controls the matrix 5 so as to reduce the transmission factor of the area corresponding to the part to which the light volume larger than the saturated light volume of the body 3 is going to be made incident. Thus the light volume larger than the saturated light volume is not made incident to the body 3.

Title: Dc machine and method and apparatus for diagnosing deterioration of insulation thereof
Inventor: MARUTANI YUJI
IPC: H02K11/00
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To take an appropriate countermeasure against deterioration of a DC machine by comparing the measurement of a megger with the measurement of an on-line megger and making a decision whether deterioration pattern of the DC machine represents partial concentration deterioration or uniform lowering of insulation. SOLUTION: In a DC motor already provided with an on-line megger 30, the DC motor 10 is stopped by turning the power supply 16 of a main circuit 14 off periodically. In place of the normally connected on-line megger 30, a megger 20 is connected periodically with the DC motor 10 by means of switches 40, 42. Based on respective measurements of the on-line megger 30 and the megger 20, a decision circuit 50 discriminates between partially concentrated deterioration of insulation and uniform deterioration of insulation of a DC machine. In other words, discrimination can be made between partially concentrated deterioration and uniform deterioration of insulation by turning the switches 40, 42 periodically or manually under setup of on-line and taking measurement by means of the megger 20.

IPC: G01N27/327
Filed: 1990-03-27
Abstract: PURPOSE:To prevent the decrease in detecting sensitivity with the elapse of time and to obtain stable detecting performance for a long period by forming a protecting film on the surface of a counter electrode. CONSTITUTION:The patterns of a measuring electrode 2 and a counter electrode 3 are formed on the surface of a ceramic substrate 1.

Title: Gas compressor
Inventor: TAKATSU HIDEHISA
IPC: F04C23/02
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To increase the inertial moment of a rotation part such as a rotor, rotor shaft, or pulley and suppress the compression torque fluctuation by providing an inertial moment addition part on the rotation part. SOLUTION: An annular inertial moment addition part 24 is extended from the circumferential part of a pulley 10 between the circumferential part of the pulley 10 and a case body 12 for covering a gas compressor body. The inertial moment addition part 24 is integrally formed with the pulley 10. When the inertial moment addition part 24 is provided between the pulley 10 and the case body 12, the inertial moment of a rotation part can be increased without enlarging the gas compressor. When the inertial moment addition part 24 is set to an annular form having a large diameter, the inertial moment/weight can be efficiently increased with hardly loosing the balance in rotation, and the manufacture is also facilitated. According to this, the compression torque fluctuation can be suppressed, and generation of an abnormal sound in a steering or piping system can be prevented.

Title: Cord tension device
Inventor: UEDA HISAAKI
IPC: B65H59/00
Filed: 1990-03-28
Abstract: PURPOSE:To prevent a cord dropping from the pull roll of a pull roll device by arranging a dancer roll for always giving tension to the cord between the pull roll device and a traverse pulley. CONSTITUTION:When a traverse pulley 91 comes to the position corresponding to the second bobbin 8B owing to the movement of a movable base, the engagement of a stopper 99 and engaging member 97 is canceled, and a cord 5 is wound around the second bobbin 8B. Since at this time, the traverse pulley 91 moves to the side of the fourth pull roll device 64 accelerating, if the winding speed of an automatic winder does not follow this movement, the cord 5 will be loosened. If the cord 5 is loosened, a dancer roll 75 is lowered due to the self weight of the dancer roll and a slider for absorbing the looseness, which prevents the cord 5 from dropping from each pull roll of the fourth pull roll device 64 resulting in the switch of the cord 5 from the first bobbin 8A to the second bobbin 28B.

IPC: H04S5/00
Filed: 1994-04-19
Abstract: PURPOSE:To apply the distance and direction feelings of a sound source to a listener by perspectively and directionally controlling a sound image outputted from two-channel speakers based on the information concerning a virtual distance between the listener and the sound source and the direction of a horizontal plane. CONSTITUTION:A sound source signal and the information concerning the virtual distance between the listener and the sound source and the direction of the horizontal plane are inputted and a perspective control part 31 judges it from the distance information whether the sound source is forward, horizontally near or backward. According to this judgement, the control part 31 respectively forms the sound images forward, horizontally adjacently and backward while using a circuit composed of an internal reflected sound generating means or a phase difference varying equipment. On the other hand, a horizontal plane sound image control part 32 inputs L and R signals and the direction information and controls the direction of sound images while using FIR0-FIR7 for L and R, multiplier 62 and adders 63 and 64. Thus, the stereo sound signals of L and R are outputted from the two-channel speakers and the listener can get the perspective and directional feelings of the moving sound source.

Filed: 1986-04-08
Abstract: PURPOSE:To detect the double setting of a disk without fail by starting the focusing action of a pick-up in response to the completion of the setting of the disk to a reproducing position. CONSTITUTION:A detecting circuit 69, when a focus locking signal (h) is not generated from the time point of generation of a setting completing signal (a) to a prescribed period T, judges that the disk is doubly set and generates a double setting detecting signal (i) as shown by a dashed line.
