Title: Differential device
Inventor: YAMAZAKI SHINJI
IPC: F16H48/27
Filed: 1995-06-30
Abstract: PURPOSE: To provide a sufficient checking function of a check valve by blocking an oil port to flow oil in the reverse direction as well as opening an oil port to flow oil in the hydraulic actuator direction from an oil reservoir. CONSTITUTION: Each of gear pumps 53 is actuated as differential rotation is generated on a differential mechanism 45, and when a sun gear 69 and a pinion gear 67 are rotated, oil ports 75, 79 come to be on the suction side and oil ports (77, 81) come to be on the discharge side. At this time, a valve plate 69 on the side of an oil reservoir 89 is oscillated, a valve part is accumulated on the discharge side oil port 77 and blocks it, and the suction side oil port 75 is opened as accumulation with the discharge side oil port 77 is released. Consequently, oil is sucked through the suction side oil port 75 from the oil reservoir 89, oil is supplied to a hydraulic actuator 51 through the discharge side oil port 81, and pressure leakage from the hydraulic actuator 51 to the oil reservoir 89 is prevented by blockage of the oil ports 79, 77.

Title: Alignment apparatus for raw material
Inventor: MURAKAMI TSUYOSHI
IPC: B65G25/00
Filed: 1990-06-25
Abstract: PURPOSE:To prevent any duplicate conveyance and to automatize alignment by installing a guiding wall on the lower position side of a slant board tilting toward the direction crossing at right angles to the conveying direction so that a conveyor plate can protrude/retreat from/in a slotted hole of the slant board in the conveying direction and make a reciprocating movement and also hoisting materials to be conveyed when the conveyor plate ascends so that excessive materials to be conveyed can be removed from the guiding wall surface. CONSTITUTION:When an electric motor 71 is driven, a sprocket 73, a chain 76 and a sprocket 75 are operated so as to put a rod 77 in circular motion. Thereby, a conveyor plate 6 is put in its reciprocating movement in both vertical and horizontal directions between the lowermost descending point and the uppermost ascending point so as to perform a reciprocating cycle movement consisting of vertical movement and reciprocating movement. Thereby, the conveyor plate 6 conveys the materials to be conveyed on a slant board 52 while hoisting them as shown in the drawing, and descends so as to return to its former position. At this time, if the conveyor plate 6 hoists the materials to be conveyed in their duplicate condition, excessive materials go beyond the upper edge of a guiding wall 53 so that, the excessive materials can be removed outside of this system due to the tilt.

Filed: 1984-08-08
Abstract: PURPOSE:To guarantee the preciseness of a block identification (ID) No. by forming a control flug storing register in addition to a register in a magnetic tape unit, turning on a control flug before updating the ID No. of a stored block and turning off the flug after the updating to detect the normality/abnormality of the block ID No. CONSTITUTION:Before the starting of the operation routine of a BLOCK-ID control circuit 12a, whether BLOCK-ID WRITE is checked or not, and if not, whether BLOCK-ID READ or not is checked. When the operation mode is not the BLOCK-ID READ, said routine ends, and if READ, an S bit in a register CFR is read out to check whether the S bit is ON or not. When the S bit is OFF, normality is decided and BLOCK-ID 0-3 in a register BIR are read out to form an expected value. When the S bit is ON, abnormality (incompletion of updating) is decided and an error alarm is generated to an upper device. If the mode is BLOCK-ID WRITE at a starting time, the S bit in the register CFR is turned on, a new BLOCK-ID is written in the register BIR, and then the S bit is turned off.

Title: Tape tension adjusting device
Inventor: KAWAI TSUTOMU
IPC: G11B15/43
Filed: 1989-06-30
Abstract: PURPOSE:To keep the tape tension of a rotary head part at the same value even when the coefficient of surface friction of a tape is different by providing a means to change the load of a balance spring by moving the position of a hooking part engaged with the balance spring of a tension detecting arm. CONSTITUTION:When tape tension is low, the tension detecting arm 1 is moved in a direction to stretch a band brake 2, and the brake 2 increases the tape tension by tightening a reel disk 3 with the balance spring 7. When the tape with a different coefficient of friction is used, the tape tension at the part of a tension detecting post 1a should be changed in order to keep the tape tension of a rotary head drum 9 constant since the frictional force of a tape guide post 11 is different from that of a tape guide post 12. A spring bar 4 is moved by rotating the rotary shaft 5a of an eccentric cam 5 by rotating the adjusting knob 5b of the eccentric cam 5, and the load of the balance spring 7 is changed, then, the appropriate tension at the part of the tension detecting post 1a can be obtained.
