Title: Regulator circuit
Inventor: TSUCHIDA YASUYUKI
IPC: G05F1/455
Filed: 1984-05-18
Abstract: PURPOSE:To suppress a rush current and to prevent a control circuit from malfunctioning by providing a circuit which raises a false signal corresponding to the effective value of a voltage applied to a load in the beginning of power-on operation and decreases it gradually. CONSTITUTION:The regulator circuit which supplied electricity to the load such as a halogen lamp as the light source of a copying machine supplies the same voltage as the full-wave rectified voltage of a load voltage from a voltage obtained by rectifying a commercial source voltage to the inverted input terminal of an operational amplifier 6 to obtain a DC voltage which is artificially proportional to the effective value of an AC voltage, and the DC voltage is supplied to a lamp voltage generating circuit 7; and the output of a comparator 8 is passed through a switch 12 to drive a two-way control rectifying element 16, turning on the lamp. A capacitor C24 is connected between the plus input terminal of the amplifier 6 or reference voltage input terminal of the comparator 8 and collector of a transistor (TR)22 and the C24 is charged when a photocoupler 11 is turned on to turn on the lamp. Thus, a soft start is made and malfunction of the control circuit is prevented.

Title: Die for die casting
Inventor: KATOU YUKIO
IPC: B22D17/22
Filed: 1981-06-29
Abstract: PURPOSE:To prevent the ejection of molten metal to the outside surely by providing a movable liner which presses objects to be cast axially freely slidably by means of a metallic bar to at least either one of a stationary die and a movable die. CONSTITUTION:A cylindrical liner 11 is fixed to a movable side die plate 15 by means of lock bolts 11a, and a movable liner 12 contacting the liner 11 tightly and slidably is fitted to said liner. A metallic bar 13 is fixed to the liner 12. In the stage of inserting objects to be cast into cavities 7 and performing die casting, if the laminated thickness of laminated iron cores 2 is larger than prescribed thickness, the die clamping between the movable die and the stationary die is transmitted to the bar 13 to elastically deform the bar 13, which in turn slides the liner 12 in a direction X, thereby holding the liner 11 and the die plate 15 tightly by having clearances l4, l5. Since the micro-difference in the thickness of the laminated layers of the iron cores 2 is absorbed by the liner 12 through the bar 13 having elastic force, the operation is progressed smoothly.

Inventor: NAKANO KAZUHIKO
IPC: G11B19/20
Filed: 1998-04-13
Abstract: PROBLEM TO BE SOLVED: To keep the rotary driving state of a disk player to be satisfactory by performing a rotary driving with a spindle motor after the chucking of a disk and also performing the chucking operation again while releasing the chucking of the disk when the level change of a signal is larger than a prescribed value while monitoring the driving signal of the motor. SOLUTION: When a disk 1 is loaded and a moving substrate 4 is displaced to an operating position, the chucking operation of the disk 1 on a truntalbe 3 is performed and a focusing control operation by a pickup control circuit 8 with respect to an optical pickup 6 is performed to detect the presence or absence of the disk. When the disk 1 is not positioned at the optimum position, a driving signal for correcting rotational unevenness is outputted by a spindle motor driving circuit 13. The level of the driving signal is monitored in a driving signal monitoring circuit 14 and the level change of the signal is inputted to a system control circuit 12, which stops the revolution of a spindle motor 2 when the level change is larger than the prescribed value and repeats the chucking operation of the disk 1 again after releasing the chucking.

Title: Valve
Inventor: KOMURO HIROSHI
IPC: F16K7/16
Filed: 1990-04-17
Abstract: PURPOSE:To improve durability of diaphragm, to eliminate influence of wear powder, and to seal a valve seat hermetically by providing a displacement system with an endless spring formed of closely wound metal wire absorbing over-travelling as well as giving a diaphragm pressure-contact force against the valve seat. CONSTITUTION:When a valve rod 24 is rotated with a handle 26 to advance a metal diaphragm 18, it abuts on a valve seat 15. Furthermore, the subsequent rotation of handle 26 compresses an endless spring 27, thereby enabling the diaphragm 18 to seal hermetically a valve seat. In this case, after the abutment, the compression of the spring 27 absorbs over-travelling of the rod and a spring seat 25 to make the displacement of diaphragm 18 the opening amount of the valve seat 15, thereby improving durability while reducing the displacement in the diaphragm 18. The provision of the endless spring 27 on the reverse side of the valve seat 15 in the diaphragm 18 serves to generate no residual gas in a passage 14 and to make the surface area small, thereby improving vacuum conditions and preventing influence of abraded powder.
