Title: Method and device for detecting clogging within piping
Inventor: NAGASHIMA KAZUHIRO
IPC: G01M11/08
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To detect clogging without measuring temperature within a piping when the clogging is found by calculating a change rate of delay time between the registered reference time and actually detected time of clogging. SOLUTION: Ultrasonic waves sent from an ultrasonic sensor 4 are transmitted in a medium within a piping 1, and reflection waves are generated in a clogging part 3, then the reflected signal waveform is inputted into a transmitting time correction device 6. The device 6 converts a trigger signal and reflected signal waveform into a digital signal through an A/D conversion circuit 23, and a delay time S in detecting clogging is calculated by a detection circuit 24 for reflected signal, further a change rate thereof is obtained according to the time S and reference time Sr, etc., registered in a reference time registering buffer 22. Then, the reflected signal waveform is corrected according to the change rate by a signal waveform correction circuit 25.  Next, the reference signal waveform registered in a registering buffer 21 for reference signal waveform is subtracted from the reflected signal waveform corrected in the circuit 25 by means of a circuit 26 for detecting clogging within piping, and as a result, a detection signal of clogging is outputted therefrom.

Title: Impeller for sirocco fan
Inventor: HANEDA KAZUHIKO
IPC: F04D29/28
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To increase the number of vanes by two times as many as that of the original vanes without changing the shape and dimension to be processed of each vane, and provide the impeller for a sirocco fan, which can boost up static pressure capacity with the pitch of the vanes kept at equal intervals. SOLUTION: In this impeller for a sirocco fan, plural cut and lifting projections 3 and 3', and plural grooves 4 and 4' are formed alternately in the longer direction at both the sides in the width direction of two inner and outer vane plates 1 an 1', and they are so constituted as to be wound twice in a cylindrical shape in such a way that the inner cut and lifting projection 3 is engaged with the outer groove 4' so as to be formed into an impeller main body, so that plural vanes 2, 2,... are projected at equal intervals within the inner circumference of the impeller main body.  By this constitution, the number of the vanes 2, 2,... can be increased by two times as many as that of the original vanes, and since the piled-up inner and outer vanes plates 1 and 1' are positively positioned because they are engaged with the groove 4' of the cut and lifting projection 3, the pitch of the vanes 2, and 2,... can be kept at equal intervals so as to allow the static pressure capacity of the impeller to be thereby enhanced.

Title: In-equipment information collecting method
Inventor: YAMAUCHI TAIICHIRO
IPC: H04B17/29
Filed: 1989-12-25
Abstract: PURPOSE:To improve the entire data collection processing efficiency by decreasing adaptively the frequency of a data requiring signal output to a unit considered to be no response normally in this in-equipment information collection method collecting the information from plural units in the equipment. CONSTITUTION:An MPU unit 11 sends a data requiring signal to each channel(CH) unit periodically via a control signal line 15, collects monitoring data information via a data bus 14 to process the monitoring data. Then the response to the data requiring signal is compared with a mounting/non-mounting setting value of all units and an alarm is outputted when no response comes from a unit set to be mounted. When no response comes from a unit set to be non- mounted, the unit set to be non-mounted is set to that the frequency outputting the data requiring signal is reduced. When a response comes from the unit set to be non-mounted, the unit set to be non-mounted is set so that the frequency outputting the data requiring signal is increased.

Title: Vibration preventing device
Inventor: NAGASE NOBORU
IPC: B23Q1/00
Filed: 1990-11-29
Abstract: PURPOSE:To reduce an impact force due to the load of a counter weight on a synchronous means by executing the synchronism of a stroke in the case of the reciprocating movement of a work holding means and counterweight by a synchronous means. CONSTITUTION:A slide member 6 and counterweight 7 are reciprocated in an independent form because of receiving the hydraulic florce of oil individually by a hydraulic driving mechanism, in the case of the slide member 6 tries to slide earlier than the counterweight 7, for instance, the counterweight 7 applies the brake via an endless belt 12, or the counterweight also tries to slide at the speed in the quickness thereof. So, the slide member 6 and counterweight 7 can be reciprocated in the synchronized state in the reverse direction each other. Therefore, the reaction force generated by the movement of the slide member 6 is almost offset by the movement in the opposite direction of the counterweight 7. Consequently, the vibration accompanied by the reciprocation motion of the slide member 6 is hardly generated from a vibration preventing device.
