Title: Method for detecting thrust force of main spindle of machine tool
Inventor: KITAMURA KOICHIRO
IPC: B23Q17/09
Filed: 1988-03-03
Abstract: PURPOSE:To improve detecting accuracy by providing pressure detectors in portions to which the thrust force of a main spindle is applied and directly detecting the thrust force of the main spindle. CONSTITUTION:A main spindle 12 is rotatably supported by a cylindrical supporting portion 20 via thrust bearings 16, 17, 18. The supporting portion 20 is fixed to a frame 15 through the flange 22 thereof with bolts 23. A pressure detector 25 utilizing a piezoelectric film is provided between the bearing 17 and the supporting portion 20 which is a bearing housing while a pressure detector 26 is also provided between the flange 22 and the frame 15. By this structure, the thrust force applied to the main spindle 12 is directly detected by the pressure detectors 25, 26 and, since no other force than the thrust force is detected, detecting accuracy can be improved.

Title: Rotary magnetic head device
Inventor: OKUNO SHINICHI
IPC: G11B5/02
Filed: 1990-02-27
Abstract: PURPOSE:To decrease the unequal torques over the entire part of the device even if a generator is connected to a revolving shaft by using a motor and generator which are the same in the frequency of the unequal torques and disposing the motor and the generator in such a manner that the phases are reversed. CONSTITUTION:A rotary drum 18 fixed to the revolving shaft 16 rotates when the shaft 16 is driven by the motor 28 of this device. A magnetic head 20 fixed to the bottom end face of the drum 18 is rotated and electromotive force is generated by the generator 38 fixed to the upper part of the drum 18. The unequal torques of 24 times are generated by one turn if a brushless motor of an axial gap type having 6 pieces of coils and 8 poles of magnets is used for the motor 28 at this time. If a generator having 24 pieces of coils and 8 poles of magnets is used as the generator 38, unequal torques of the same number thereof are generated. This motor 28 and generator 38 are, therefore, so disposed that the phases are reversed to offset the unequal torques of both.

Filed: 1993-02-15
Abstract: PURPOSE:To accurately test a counting function for the number of particles for smoke particles which gives a concrete index of how much the generated smoke is when a smoke sensor is a type of counting the number of particles. CONSTITUTION:When a transmission repeater T1 sends a test signal TST, a test light source 21 emits pulse light as many times as specified within a specific period. This pulse light is made incident directly on a photodetector 12 for particle detection, which reacts to it in exactly the same way with the reception of light scattered by smoke particles. Then the detection signal outputted from the photodetector 12 for particle detection is amplified by an amplifier 14, compared by a comparator 15 with a reference voltage, and outputted as a particle signal (pulse signal) PT. This particle signal PT is sent to the part 42 for counting the number of particles of the transmission repeater T1 and counted there and a receiver RC decides whether or not the counting function is normal on the basis of the counting result.

Title: Refuse truck
Inventor: MAEDA NORIO
IPC: B65F3/02
Filed: 1988-03-03
Abstract: PURPOSE:To make it possible to extend the whole length of a container by dividing a packer section continuously connected with a refuse housing container into a front and a rear section so as to let the rear packer section be rotatably supported by the lower section of the front packer section in such a way as to be freely rotated up and down, and thereby using the rear packer section as a charging device concurrently. CONSTITUTION:When refuse is charged in, a rear packer section 6 is rotated downward from a line indicated by a solid line to a line indicated by a dash line with a hydraulic cylinder 7 contracted so that refuse is charged into the rear packer section 6. When the rear packer section 6 is full of refuse, the rear packer section 6 is rotated upward with the cylinder 9 extended. This constitution allows the front and rear packer sections 5 and 6 to form a closed packer 3, and after refuse has been housed in the packer section 3, refuse housed in the front and rear packer sections 5 and 6 is pushed into a container 2 with a forcing device 4 actuated. Thus, the container 2 can be made full of refuse by repeating the aforesaid operations. In the second place, when a trunk is running, the rear packer section 6 is positioned to a line indicated by a solid line with the cylinder 9 extended. The truck therefore runs with packer 3 closed, thereby enabling a rear overhang L to be kept within the length specified by law.
