Title: Magnetic recording medium
Inventor: KAWABE SADANOBU
IPC: G11B20/12
Filed: 1979-09-13
Abstract: PURPOSE: To reduce readout errors of an address signal for positioning the beginning of a magnetic recording medium by composing the address signal of three kinds of start, binary address code and end signals and by putting those signals out of phase with a timing signal by steps.  
     CONSTITUTION: In forward reproduction, start signal (s) is detected by the 1st clock generated being (T 1 /Tv)×100% of reproduction period Tv' out of phase with control signal CTL and an address signal is detected by the 2nd clock generated being (T 2 /Tv)×100% of signal CTLTv' out of phase. Further, end signal (e) is detected by the 3rd clock generated being out of phase by (T 4 /Tv)×100% of signal Tv'. Thus, three kinds of start, address and end signals are separately extracted and only when those signals are all obtained, the correct address is displayed. In reverse reproduction, on the other hand, the polarity of each signal is only inverted.

Abstract: PURPOSE:To prevent occurrence of defective copying and enable sure copying at all times by rotating the photosensitive drum reversely and peeling off paper powder from the blade. CONSTITUTION:A device 22 that rotates the photosensitive drum 21 reversely only once by making a switch S20 in the operation panel on, a copying lamp 23, a main motor 24 etc. are provided. Normally, the drum 21 is rotated only in the direction of the arrow A. At that time, the tip 25a of a blade 25 is in contact with the peripheral face as shown by dotted lines. When the drum 21 is rotated reversely in the direction B, the blade 25 comes to a position shown by solid lines. Under this condition, the blade 25 is bent forcibly, and the tip face 25b comes into contact with the peripheral face of the drum 21. Thus, paper powder accumulated on the tip 25a is peeled off from the blade 25.

Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To obtain a ferrite magnetic material having excellent magnetic characteristics which is achieved by sintering pre-sintered ferrite powders each having the diameter of a specific value or smaller at a low temperature. SOLUTION: MnCo3 , ZnO, and Fe2 O3 each having the grain diameter of 1 to 4μm are used as starting materials and are subjected to wet blending at a predetermined ratio. After pre-sintering in an atmosphere, the materials are ground so that the grain diameter is 0.5μm or smaller. Polyvinylalcohol aqueous solution is added to the obtained pre-sintered ferrite powders and they are mixed and molded. The moldings are sintered in an atmosphere at a low temperature of about 1,000 deg.C. The density and magnetic permeability of the sintered body as an index of the degree of sintering are improved and a ferrite core having excellent magnetic characteristics can be obtained.

IPC: B09B3/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce the electric power consumption in a period until an org. matter treating apparatus is used by providing the apparatus with an opening/ closing detecting means for detecting the opening and closing of a cap and a control means for controlling an agitating body in accordance with the detection result of a load detecting means after closing the cap. SOLUTION: When a speed of >=V0 at which the agitating body rotates in the state of supplying the org. matter is detected (S5), the agitating body is stopped and is made to stand by (S6). When the speed is V0 or below (S5), org. matter is treated by controlling the agitating body, a panel heater and an exhaust fan (S7). When the opening of the cap is detected (S8), the energization to the agitating body and the panel heater is stopped (S9). When the closing of the cap is detected (S10), the driving of the agitating body and the energization to he panel heater are resumed (S11). When a shutter is removed (S12), the energization to the agitating body, the panel heater and the exhaust fan is stopped (S13) to save electricity.

Abstract: PURPOSE:To prevent useless sliding movement of an original placing table, by providing a clutch which couples a motor with the original placing table so as to transmit the rotation of the motor to the table at the time of advancing movement of the table and cuts of the motor from the table when the table makes returning movement, between the motor and original placing table. CONSTITUTION:When a motor 51 is driven, an original placing table 2 is slid and an original placing table stopping cam body 91 comes into collision with an engaging member 78 on the original placing table side. Then the member 78 rotates and its click section is separated from the tooth of a ratchet gear 73. When the click section is separated from the gear 73, a spring clutch 62 is disengaged and the original placing table 2 is stopped. Moreover, since another engaging member 89 on a platen side is also rotated when the engaging member 78 is rotated, another spring clutch 88 on the platen side is also disengaged and rotation of the platen 42 is simultaneously stopped. When the original placing table 2 is manually moved, it can be brought back to the original position. Whereas the stopping location of the original placing table 2 is fixed, the sliding starting location of the original placing table 2 can optionally be selected in accordance with the size of an original, since the table can be moved backward manually.

CONSTITUTION:As a green tire is supplied from above, a clamping claw 26 is widely opened and an arm 43 is lifted and the tire is placed and held securely on a green tire clamping device A-2. This condition is maintained until a tire T in the previous cycle is vulcanized in a press. Upon completion of vulcanization of the tire T in the previous cycle in the press, the upper and lower metal molds of the press are separated and the completed tire is discharged outside the press. In the meantime, the green tire clamping device on a green tire delivery device A-1 rotates around a revolving shaft 14 and it is reversed. By this reversion, the green tire becomes in hanged condition, and then the green tire delivery device A-1 moves to N.2 position from No.1 position. The hanged green tire T is stopped at No.2 position and its raw beads are caused to seat on the lower bead ring by causing the green tire to approach to the lower bead ring of the lower metal mold, or by causing the lower bead ring to approach to the green tire.
