Title: Cover mechanism for original platen
Inventor: ETSUNO SUSUMU
IPC: G03B27/62
Filed: 1987-06-19
Abstract: PURPOSE:To bend a cover and to cover an original adjusting to the shape of the upper surface of the original even if the original is a thick one such as an open type book by constituting the cover in such a way that it can be bent nearly in the center. CONSTITUTION:The titled mechanism provides the plate-shaped cover 3 covering an original platen and one end of the cover 3 and a device main body are linked freely rockably by a hinge 4. Bendable parts 3a and 3b parallel with a rocking axis by the hinge 4 are formed nearly in the center of the cover 3 and leading edge side from the bendable parts 3a and 3b is made to freely rock independently of the link part with the device main body 2. Namely, the bendable parts 3a and 3b are formed by thinning the thickness of the cover 3 made of synthetic resins in a V-shape and they can be bent independently. Thus, the cover can uniformly cover the entire original not only in the case of thin paper original but also in the case of thick original such as a book, etc.

Filed: 1988-06-23
Abstract: PURPOSE:To perform a stopping position control with high accuracy even if a hydraulic cylinder is used by feeding return oil from the hydraulic cylinder to an auxiliary cylinder and controlling a stroke of the hydraulic cylinder in only a prescribed length. CONSTITUTION:When a solenoid 11b of a solenoid valve 11 for position control is energized, pressurized oil from a hydraulic supply piping P flows into a control piping 12b to pressurize a rod side of a hydraulic cylinder 7 and to move a piston toward a head side. At that time, return oil from the head side of the cylinder 7 flows from a control piping 17a to the head side of an auxiliary cylinder 16 through a pilot check valve 19 because the pilot check valves 19, 22 are opened by pressurized oil passed through the control piping 12b. The return oil flowing from the auxiliary cylinder 16 side flows in a return oil piping T and returns to a hydraulic oil tank by action of a pilot check valve 20. Therefore, a stroke of the cylinder 7 acts in a prescribed length and stops by previously setting a stroke of the cylinder 16 by a prescribed length.

Abstract: PURPOSE:To quicken the rise in temperature of a person mounting table, by a method wherein the person mounting table and a timer are started simultaneously when no person is detected on the table, and the main body temperature is controlled according to the temperature set by the user immediately when a person is detected on the table during the operation of the timer. CONSTITUTION:The voltage of an output 47 is obtained by dividing a direct current voltage V27 indicated at 27 by resistors 10, 11, and voltage V48 indicated at 48 is determined by division of resistors 8, 9 and a resistance of a conductive pressure conductive element 7. When a person is placed, the output 49 of a comparator 23 becomes HIGH, and the main body temperature is set by a user. When no person is placed, the signal of the output 49 becomes LOW, therefore the R terminal input signal becomes HIGH, a timer is set with the S terminal input signal being HIGH, and a divider starts counting. During this counting, the main body temperature is kept low. Thereafter, when time is up, the Q signal becomes LOW, the short-circuited S terminal input signal becomes LOW, and electric current is not passed to a heater.

Title: Automatic vertical electrogas welding device
Inventor: OTOGURO MITSUAKI
IPC: B23K9/095
Filed: 1980-10-31
Abstract: PURPOSE: To prevent lack of penetration, defects of bead appearance, etc. by controlling welding in such a way that the traveling of a welding carriage is  started upon attainment of welding electric current at a reference welding current value.  
     CONSTITUTION: Reference welding current is set by a reference welding current setter 22a, and actual welding current is detected by a shunt 23 and is compared with reference welding current. When the actual welding current is larger than the reference current, the normally open contacts 24a of a relay 24 are closed, and the motor of a welding curriage runs at a high speed. When the actual welding current is small, the normally open contacts 24a of the relay 24 are opened to run the motor of the welding carriage at a low speed. Under automatic control in this way, vertical welding is accomplished by an electrogas welding method while a small diameter flux cored wire is oscillated at a high speed in the thickness direction within the groove of the work.
