Title: Scroll compressor
Inventor: TERAUCHI KIYOSHI
IPC: F01C1/02
Filed: 1983-11-14
Abstract: PURPOSE:To prevent generation of vibration at the part with play of a ball coupling part by giving a spiral member of movable scroll a lap length greater than that of the spiral member of stationary scroll. CONSTITUTION:The length of a spiral 22 of a movable scroll shall be greater than that of the spiral 21 of stationary scroll. Difference between the spiral lengths of these scrolls causes asymmetricity of the gas pressure distribution in the enclosed space, and the combined force Fg of gas pressure will shift to the higher side in pressure distribution than when the two scrolls have the same number of turns in their spirals. This will generate a couple of forces in the scrolls to cause increase of the force applied to the ball coupling, which serves for prevention of vibration likely otherwise to be generated from the play part of the coupling.

Abstract: PURPOSE:To obtain a magnetic toner having high electric conductivity, low softening point, and goo fixability, and suitability for pressing transfer by incorporating a conductive carbon black specified in each of particle diameter, surface area, oil adsorptivity, and particle diameter distribution. CONSTITUTION:A conductive carbon black (CB) having 10-50mum particle diameter, 100-300m<2>/g surface area measured by the N2 adsorption method, 100-200cc/100g dibutyl phthalate adsorptivity, and at least 2 peaks in particle diameter distribution is incorporated in a binder resin in an amt. of 20-30wt% of the resin to obtain a one-component developing magnetic toner. The 2 peaks of the CB distribution are preferably located, e.g. in the ranges of 5-30mum and 10-50mum, and since CB small in size is easy to form a electrical path but low in dispersibility in the resin, this defect is covered by the combination of CB larger in diameter. As a result, the obtd. toner is low in softening point and improved in fixability and enhanced to 10<-4>-10<-12>ohm/cm in toner conductivity, in DC 1,000V, and hence, suitable for pressing transfer use.

Abstract: PURPOSE:To obtain life reliability improvable with a load reduced in ball bearings by arranging the one ball bearing in an electric motor element side and the other opposite to the electric motor element side from an eccentric part of a crankshaft, of the two ball bearings for rotatably supporting the crankshaft. CONSTITUTION:A ball bearing 28 is inserted to a crankshaft 25 to which a thrust plate 34 is fixed by a bolt 35. Thus by arranging bearings 27 and 28 in an electric motor element side and in a side opposite thereto from an eccentric part 26 of the crankshaft 25, in a compressor, a load by reaction of a compression load of a piston 14 is almost equally received by the bearings 27 and 28. Accordingly, a load for the bearings 27 and 28 can be reduced with life reliability possible to be enhanced. While when a spring 32 is inserted between an outer frame part 31 of the bearing 28 and its bearing part 30, a thrust load of the spring 32 + dead weight force of the crankshaft 25 and a rotor 4 acts on the bearing 27 with the thrust load of the spring 32 acting on the bearing 28, and a sliding noise can be low suppressed.

Title: Clutch
Inventor: IMAZATO KAZUNARI
IPC: F16D25/0635
Filed: 1982-12-07
Abstract: PURPOSE:To eliminate necessity for use a large quantity of pressure oil by furnishing a chamber behind a push-aside chamber, filling these two chambers always the same working fluid, thereby balancing the oil pressure force produced by centrifugal force, and thereby eliminating necessity for use of a check valve. CONSTITUTION:A push-aside chamber 5d is furnished between a piston 5 and a reactive member seen in their axial direction, and another chamber 5c is provided behind this push-aside chamber 5d, and connected with a reserver. When fed into this chamber 5d, the pressure oil pushes the piston 5 to the left, and a clutch plate 6 and transmission piece 3 rotate together as in a single piece. In this action, the oil pressure force in the push-aside chamber 5d is entirely balanced with that in the chamber 5c, even when the former 5d is free from application of pressure oil, because the same oil pressure force owing to centrifugal force is generated in the two chambers.

Title: Rotary head type magnetic recording and reproducing device
Inventor: SATO SUKEYUKI

Filed: 1984-10-11
Abstract: PURPOSE:To make variable fixed hysteresis width outside an integrated circuit by envelope-detecting a reproducing signal from two magnetic heads, extracting selectively the reproducing signal by an output of a comparing means compared and feeding back the output of the comparing means to a detecting means. CONSTITUTION:An output terminal P1 of a comparing circuit and a C2 terminal of a detecting means are connected through feedback resistance RX. Thus, when the signal inputted to respective input terminals to envelope detecting circuits are represented by Figs. A and B, an output (Fig. C) of the terminal P1 is fed back to the terminal C2, and therefore, a detecting voltage A' of a terminal C1 will not be influenced by the feedback, but, a detecting voltage B' of a terminal C2 becomes higher a little as shown by dotted lines when a C waveform is in a high level and becomes lower a little when it is in a low level. Consequently, hysteresis width can be changed equivalently by selecting the value of the resistance RX.
