Title: Fine adjustment device
Inventor: MURAKAMI ICHIRO
IPC: B23Q5/22
Filed: 1987-05-07
Abstract: PURPOSE:To enable the positional adjustment of a movable body with extremely high precision by adjusting the position of the movable body in an aslant direction via the adjustment of the position of an adjustment member to be shifted in a direction orthogonal with the inclination direction. CONSTITUTION:When a stepping motor 49 turns, a slide plate is shifted and the position thereof in a back-and-forth direction changes for the support base 15 of a slide block 12 at a point opposing the contact pin 38 of the adjustment surface 45a of an adjuster 45. Namely, the height of a position opposite to the contact pin 38 of the adjustment surface 45a gives a change. When a hydraulic cylinder 26 is actuated in this condition and an adjusted block 31 is made to advance, this block 31 stops moving at the position where the contact pin 38 comes in contact with the adjustment surface 45a of the adjuster 45, thereby determining the position of the adjusted block 31 in an inclination direction. The adjustment amount of the adjustment direction for the block 31 appears as the sine function rate of an inclination angle for a direction orthogonal with the adjustment direction, thereby giving an extremely small adjustment rate.

Title: Dc high voltage power
Inventor: TOMITA MAKOTO
IPC: G05F3/08
Filed: 1992-04-30
Abstract: PURPOSE:To prolong the duration of high dust colletion efficiency and to improve reliability by connecting a specified electric resistance between an ionizer and a DC high voltage generation part. CONSTITUTION:The resistance of 300KOMEGA-40KOMEGA is connected between the ionizer 3 and the DC high voltage generation part 2 in serial or the difference of output power at non-load time and low cost load duration time is set to be 0.5KV-3KV. An output voltage change rate against the change of load current is set to be large and the change of load current owing to load fluctuation is reduced. When high resistant particles are adhered to an electrode part and the current of the ionizer 3 is reduced, the shared voltage of the serial resistance and the ionizer 3 becomes high and the reduction of the current of the ionizer 3 is to be suppressed. Thus, dust collection efficiency is maintained. Namley, ionizer current I is reduced, the voltage E2 of the serial resistance R drops and the voltage E1 of the ionizer 3 becomes high when the resistance RL of the ionizer 3 becomes high. Thus, the dust collection efficiency of an air cleaner is always stabilized and high reliability can be obtained.

Title: Drying method of metal powder
Inventor: YAMAMOTO YASUSHI
IPC: F26B3/22
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To efficiently dry even such a powder that has rather large specific gravity by housing a metal powder as the objective powder with wear-resistant spheres in a metal container having good thermal conductivity, heating the metal container while the container is being vibrated so that the spheres collide with the metal powder in the container. SOLUTION: A metal powder 4 such as a rapidly solidified metal powder is housed in a metal container with a plurality of spheres 3, and the metal container 1 is heated through the lower part by a hot plate 2. At the same time, the metal container 1 is vibrated to allow the spheres 3 to collide with the metal powder 4 in the container 1. By this method, although the wet metal powder 4 is in a state which easily causes aggregation, the spheres 3 are made to collide with the metal powder 4 to loosen by vibrating the metal container 1. As a result, the heat of the heated metal container 1 is efficiently transferred directly to the metal powder or through the spheres 3. Therefore, the drying rate of the metal powder 4 is increased and the obtd. metal powder 4 has less surface oxidation.

Filed: 1994-05-26
Abstract: PURPOSE:To encode a transmission signal and a reception signal correctly even when connection in which the polarity of a transmission line is reversed exists by inverting the polarity of the reception signal. CONSTITUTION:A transmission signal of polar binary format is inputted to the transmission line interface 8 of terminal equipment via the transmission line 3, thence, to a reception code inversion means 10. In the means 10, a code transmission control circuit 12 judges an inverted reception code outputted from a reception code inversion circuit 15 as a reception code of positive logic when it is generated at the voltage level of a marked state. When the inverted reception code is of negative logic, or, the output of a transmission signal generation circuit 13 is set in a permitted state, a prohibition instruction to output a transmission signal in a prohibited state is issued from a transmission signal generation circuit 14. A reception code selection circuit 16 selects either the reception code or inverted reception code in accordance with the circuit 13 or circuit 14 set in the permitted state, and outputs a normal reception code to a code processing circuit 9. In this way, the circuit 9 can send normal data to a CPU 30.
