Patent JP-S567103-A (JP)
Title: Operation end controller
Inventor: HIROI KAZUO
IPC: G05B11/32
Filed: 1979-06-28
Abstract: PURPOSE: To realize the energy saving with the controllability being maintained, by giving the opening degree adjustment to the damper with the operation signal and then maintain the damper's opening degree within the fixed range by giving the control to the rotational frequency of the motor in case the opening degree exceeds the fixed range.  
     CONSTITUTION: In case the operation signal has a sudden change, damper 3 is driven by damper driving part 2. And no signal is delivered from decider 4 in case the operation signal is within the set range of the upper/lower limit decider 4. Thus setting unit 5 holds the preceding output value, and accordingly blower 8 keeps the rotational frequency of that time. In other words, the flow rate of the exhaustion is controlled only by damper 3 with a high responsiveness. While in case the operation signal is out of the set range, the opening degree of damper 3 is decreased immediately to reduce the flow rate. At the same time, the decrement signal is delivered from decider 4, and thus the setting unit 5 decreases the output signals to be supplied to frequency converter 6. Accordingly, the rotational frequency of AC motor 7 is reduced and then the ventilation quantity of blower 8 is reduced. As a result, the exhaustion quantity is reduced more, and thus the operation signal changes toward the increment of the opening degree of damper 3, i.e. to the value within the set range.

Title: Drill
Inventor: SUZUKI YASUHIRO
IPC: B23D77/00
Filed: 1992-03-03
Abstract: PURPOSE:To enhance the druability of, and facilitate re-grinding of a workpiece by, a drill generating less flashes during a through-hole fabrication. CONSTITUTION:The inner peripheral surface of a hole formed with use of a first main cutting edge 42 and a first subsidiary cutting edge 48, both constituting a drill cutter, is finished by CBN-made second main cutting and subsidiary cutting edges, both constituting a reamer blade. Through forming the second main cutting edge 52 into a shape the outer periphery of which is 1/4 of the ellipse circumference, the amount of cut into a workpiece by the second main cutting edge 52 becomes small while, at the same time, the cutting force becomes small. Therefore, generation of burrs during through-hole fabrication is lessened while, at the same time, regrinding becomes easy. In addition, since the hardness of the reamer cutter is increased, the wear resistance is improved to enable long-time working.

Title: Horizontal rotary compressor
Inventor: YAMAJI NAOYO
IPC: F25B1/04
Filed: 1993-04-08
Abstract: PURPOSE:To prevent a lowering of the viscosity of oil by a method wherein the external surface of a suction pipe is covered with a nonmetal film having affinity to a liquid refrigerant and the suction pipe is made of a nonmetal material having affinity to the liquid refrigerant. CONSTITUTION:A refrigerant compressed in a compression chamber 8 is discharged into a discharge chamber 17a from a discharge valve provided on a sub side housing 7 and circulates through a discharge pipe, a condenser, a decompression pipe, an evaporator and a connecting pipe to be returned again to the compression chamber 8 through the suction pipe 18. Here, the external surface of the suction pipe 18 is covered with a non-metal film 24 having affinity to a liquid refrigerant and the material itself of the suction pipe 18 is made of a nonmetal material having affinity to the liquid refrigerant. As a result, heat exchange is checked in the suction pipe and a closed container to suppress the liquefaction of the refrigerant on the surface of the suction pipe. This also does not allow the dripping of the liquid refrigerant into oil because of the affinity of the surface of the suction pipe to the liquid refrigerant even when the refrigerant is liquefied to adhere to the surface of the suction pipe thereby eliminating drop in the viscosity of the oil.
