Title: Impeller structure of multiblade blower
Inventor: SATO SEIJI
IPC: F04D17/04
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To reduce the air noise by trailing vortex by forming the outside or inside, or outside and inside blade ends of the blade of an impeller into a sawtooth structure. SOLUTION: A plurality of blades 19, 19... are provided with sawtooth structures 20, 20... on the outer circumferential blade ends (air inlet-side blade ends).

Title: Electrophotographic developer
Inventor: WATANABE AKIHIRO
IPC: G03G9/10
Filed: 1992-11-17
Abstract: PURPOSE:To make the formation of a high quality image possible without fog while having sufficient solid image density by containing a magnetic carrier and toner respectively having specific characteristics. CONSTITUTION:An electrophotographic developer contains a magnetic carrier and toner. A ratio between the sum Sc of surface area of magnetic carrier grain contained per unit weight of the developer and the sum ST of surface area of toner grain is A(=ST/Sc)<=2.5, and a ratio between the ratio A and the current value I of the magnetic carrier is I/A>7. The current value I of the magnetic carrier in this case means the current value at the time of D.C. voltage of 200V being applied in the state of the magnetic carrier moving as well as forming a magnetic brush on a developing sleeve. When the ratio if the toner to the magnetic carrier in the developer is increased, the toner is easily shifted to a photosensitive body, so that fog is liable to generate, and the charge quantity of the individual toner becomes insufficient so as to lower the quality of a formed image. In order to prevent this, the radio A is kept in such a way as not to exceed 2.5.

Title: Press roll device for preventing bucking of edging press
Inventor: TAZOE NOBUHIRO
IPC: B21B15/00
Filed: 1986-12-22
Abstract: PURPOSE:To prevent the buckling to be generated in a rolled stock at the time of edging by forming one of upper and lower press rolls as a position fixed roll having a centrally recessing hourglass shape and forming the other as a liftable and pressure variable roll. CONSTITUTION:A cylinder 5 is actuated to lower the upper press roll 4 and the rolled stock 7 is pinched by the upper and lower press rolls 4, 1, then both ends of the rolled stock 7 are edged and pressed by press dies 6 in the case of edging and pressing the rolled stock 7. The rolled stock 7 is going to crown downward from the relation of pressures P1>=P2, but the parts near both ends of the rolled stock 7 contact the projecting parts of the lower press roll 1 and are pressed upward by the force of P1/2 on one side. The rolled stock 7 in the central recess of the lower press roll 1 is pushed and projected downward by the upper press roll 4. The rolled stock 7 is thereby formed to the sectional shape in which the central part is slightly larger in thickness than both ends as a whole. The formation of a buckled shape is thus prevented.

Title: Trough broken position detecting method
Inventor: ANDO KOJU
IPC: H02G9/00
Filed: 1991-10-29
Abstract: PURPOSE:To make it possible to easily detect a break of a trough and the position of the break by laying detecting wires alternately from main body of trough to lid of trough repetitively. CONSTITUTION:A detecting line 8 is so arranged that it is connected from main body of a trough 3A to lid body of trough 3B alternately and repetitively along the flange 4B. In this case, the detecting line 8 is attached to the upward- projected portion of a bolt 5 and then downward projected portion of the bolt 5 alternately and repetitively. The detecting line 8 returns back at the one end of the trough 3 and goes back along the other flange 4A to the starting point, and both the ends are connected to a detector 9. If a constant current is always applied to the detecting line 8, the detector 9 has two sections, one of which detects the current values, and other section detects the point where the detecting line 8 is broken. Thus, if the joint between the main body 3A of trough and the lid body 3B of trough is broken due to the thermal expansion force by cables 1 and this force is applied to the detecting line 8, then the detecting line 8 is broken and this is detected.
