Title: Cross flow type blower
Inventor: YOSHIDA AKIRA
IPC: F04D17/04
Filed: 1987-05-14
Abstract: PURPOSE:To reduce noises by providing a flow hole through which a swirl discharged from an air outlet reflows into an impeller between a first tongue and a second tongue provided in the air outlet. CONSTITUTION:First and second tongues 10a, 10b are provided in outlet 3 of fluid from an impeller 5. A flow hole 11 is provided between both tongues 10a, 10b. Main air flow 12 generated by the rotation of impeller 5 is blown out of the outlet 3 while a portion of swirl 13 generated on the upper portion of outlet 5 will be turned around the tongue 10a and resucked from the flow hole 11 into the impeller 5. Thus, air flow does not pass through a narrow gap so that noises can be reduced.

Title: Abnormal discharge quenching device for vacuum equipment
Inventor: YAMAGUCHI HISAO
IPC: C23F4/00
Filed: 1995-05-17
Abstract: PURPOSE: To prevent interruption of the power supply to an vacuum equipment over a long period of time from occurring by closing a switch connected to a load-connecting circuit in parallel with the vacuum equipment when any change in load voltage due to an abnormal discharge is detected. CONSTITUTION: In this device, a switch 23 and electric resistance 22 are connected to a load- connecting circuit for connecting a DC power source 1 to a vacuum equipment 3, in parallel with the vacuum equipment 3. When any change in load voltage due to an abnormal discharge in the vacuum equipment 3 occurs, the abnormality is detected by an abnormal discharge voltage detector 17 and the change in load current value to an overcurrent level is detected by a current detector 13. When the abnormal signals from the detectors 13 and 17 are received by a control circuit 14, the output of the DC power source 1 is reduced and concurrently, the switch 23 is closed by the control circuit 14. At this time, the energy accumulated in reactors 8 and condensers 9 is consumed by the resistance 22. Accordingly, the output of the DC power source 1 is reduced in a short time and the vacuum equipment 3 is returned to the constant-power operation at once. Thus, the interruption of power supply from the power source 1 over a long period of time of the order of several milliseconds is prevented from occurring and the operation of the vacuum equipment 3 can be performed almost without any dead time.

Filed: 1987-05-15
Abstract: PURPOSE:To improve the operability by setting a write mode when a specific time is elapsed after a preset key is operated, and limiting the time of the write mode and returning said mode to an initial mode when the time is elapsed. CONSTITUTION:A control part when receiving a depression signal from the preset key 13 turns on a display element 14 and also sets a call mode. At the same time, the control part starts time measurement, and resets the call mode a 1st reference time T1 later and sets the write mode while lighting the display element 14. Further, when an operation stop signal is received from the preset key 13 in the write mode after the 1st reference time T1 stores a frequency signal in the storage area A corresponding to the preset key 13, the control part 3 resets the write mode and returns to the initial state a 2nd reference time T2 after the 1st reference time T1 is elapsed. Consequently, the misoperation of the preset key is canceled properly and the operability is improved.
