Title: Rotation mechanism for minute angle
Inventor: NISHIMURA KAORU
IPC: H01J49/06
Filed: 1985-05-27
Abstract: PURPOSE:To obtain a rotation mechanism for minute angle with low cost by supporting the slit side of a slit rod via a pair of elastic materials and also providing the 1st and 2nd feed mechanisms to give displacement to the slit rod. CONSTITUTION:The other side of a slit shaft 23 is displaced linearly in the direction vertical to the lengthwise direction of the shaft 23 by means of the 1st screw feed mechanism 27. Thus a slit 23a is rotated by a minute angle together with control given from a pair of elastic materials 21a and 21b. Here the slit 23a is displaced in its width direction, i.e., toward the lengthwise direction of the slit rod 23. Furthermore a screw 19 serving as the 2nd feed mechanism is available as necessary for control to correct the displacement of the slit 23a due to its rotation by a minute angle. In such a way, a rotation mechanism for minute angle is obtained with low cost.

Abstract: PURPOSE: To prevent the freeze of cooling medium by forming a part of main pipe in each cooling system in common to allow circulating water in each apparatus to be mixed, in a system which is equipped with more than one electrical cooling apparatuses which use liquid as cooling medium.  
     CONSTITUTION: A system (1) is in operation, and a system (2) is a preleminary system in stop, and pumps 5 are always in operation and mixe and circulate the cooling water in two systems. As the system (1) is in operation, the cooling water having flowed-out from a rectifier 1 has a high temperature, and in the system (2),  heat-geration from a rectifier 1 does not arise, and the rise of temperature of cooling water is not observed. When the cooling water in the state above described flows out from each rectifier 1 and is mixed in a common main pipe 7, the temperature of cooling water after mixing becomes a mean temperature of each cooling water, and the wtaer branches into each system from the exit of the common pipe 7. Thus, the freeze of cooling medium in the system in operation stop can be prevented

Title: Inverter device
Inventor: MORI ISAO
IPC: H02M7/515
Filed: 1977-09-27
Abstract: PURPOSE: To provide the subject device wherein a circuit for dividing the output voltage of a commutation auxiliary power source is provided, the thus divided voltage is applied to the commutation circuit to cause the device to stand by in a no-load running state, thereby to reduce the commutation loss.  
     CONSTITUTION: An inverter device provided for the backup at an emergency is provided with circuits 31A and 32A for dividing the output voltage of a commutation auxiliary power source 31, and this divided voltage is applied to a commutation capacitor 27 to cause the same to stand by in a no-load running state. During the stand-by time a switch 33B is closed by the output of a switch selecting circuit 34 to lower the commutation auxiliary source voltage. In accordance with this operation the charging voltage of the commutation capacitor 27 becomes lowered correspondingly, and the commutation impulse current is also lowered. That is, during the stand-by time the inverter is driven under its low commutation function. However, since it is driven in a non-load state, the load current is zero but it is sufficient for the commutation. As a result, the commutaion loss can be reduced, and further since the power is carried constantly, the reliability on the device can be improved
