Title: Motor-driven dust collector and dust collecting sanding machine
Inventor: SANO GENZO
IPC: B24B55/10
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To endure a long-term continuous operation without excessive burden due to the occurrence of clogging in a filter in a short time by separating most of dust by means of a cyclone before it arrives at a filter and storing it in a dust storing chamber. SOLUTION: Dust 10 is sucked into the cylindrical part 3a of a cyclone generating chamber 3 from a sucking port 7 together with an air stream 9. Dust 10 and the air stream 9 are revolved in a vortex state inside the cylindrical part 3a. Dust 10 is scattered in a peripheral direction by centrifugal force and separated from the air stream in the vortex. Separated dust 10 is moved downward along the inner wall surface of the cylindrical part 3a and the inner wall surface of a conical part 3b and goes down from the opening of a conical part end into a storing chamber 2. Therefore, most of sucked dust does not arrive at the filter 5 so that a motor is prevented from becoming out of order owing to the clogging of the filter 5.

Title: Display circuit for reception frequency
Inventor: TAKITANI TAKESHI
IPC: H04B1/16
Filed: 1979-10-01
Abstract: PURPOSE:To simplify the adjustment of the circuit as well as prevent the misdisplay, by counting the intermediate frequency given from the intermediate frequency amplifier and then counting the local oscillation frequency to display the reception frequency. CONSTITUTION:The intermediate frequency is supplied to the up-down counters 12a from the terminal 10 via the gate circuits 18 and 20. At the same time, the intermediate frequency is applied to the level detector 16, and the output becomes L and H when the voltage level of the intermediate frequency is normal and abnormal respectively. In case the contents of the counters 12a are normal, the IF data latch signal TD is generated from the timing control signal generating circuit 24 to be stored in the IF data latch circuits 15a. Then the local oscillation frequency is supplied to the counters 12a by the timing control signal T2 to be counted. After this, the data transfer pulse TL is generated and then latched to the display latch circuit 13a, and thus the reception frequency is displayed through the display circuits 14a. In case some fault occurs, the contents of the counter are not latched. And then the preset signal P is generated, and the contents of the latch circuit are transferred to the counter. After this, the same operation as that of the normal time is given.

Abstract: PURPOSE:To listen the traffic information at the irreducible minimum of a demand to eliminate several harsh listening frequencies of the information by actuating a timer after reception of a carrier signal and then cutting the supply of power after a prescribed time. CONSTITUTION:When a power switch 6 is turned on, a radio part 2 is set in a receivable state by the power supplied from a power supply 1. The carrier radio waves are received from a highway radio station at a time point t1, and the voice signals are transmitted through a speaker 3. The carrier signals 1 generated at the part 2 is detected by a detector 4 and at the same time a signal P is transmitted. A timer 5 is started by the signal P after a prescribed time t2 and counts the time for a prescribed time T. The voices are continuously generated through the speaker 3 for about 50 seconds by the voice signals. The time-up time of the timer 5 is previously set at 50+10>T>50 seconds and therefore the traffic information can be heard in a satisfactory state since the part 2 is kept in a receivable state even after 50 seconds when the voice signals are continuously transmitted. The switch 6 is turned off in the time-up state of the timer 5 and the voice signals automatically disappear. The traffic information can be heard again with push of a monitor switch 7 even when the first traffic information is missed.

Air in the room 10 is sucked by a vane 2 driven by the electric motor 1, the air passes through a louver 9 and an orifice 8. The air is discharged from a bent cap 16 outside 17 of the room. As the air humidity in the room 10 is less than the humidity set by the humidity setting knob 14, the control part 12 stops the operation of the electric motor 1. In this way, the humidity sensor 11 and the control part 12 are assembled compact between a flange 6 and the louver 12. Installing operation for the fan for the pipe can be automatically and easily operated. One power supply cord 15 is satisfactory for the operation and then an interior characteristic after installing operation can be improved.
