Title: Device for screwing tip to body of mechanical pencil
Inventor: FUJIYOSHI TORU
IPC: B43K21/26
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To shorten a contact time required for a tip to be automatically screwed into the body of a mechanical pencil. SOLUTION: Tip retaining members 4 are arranged radially on a rotary disc which rotates intermittently in one direction, then a driven gear 9 is fixed to the shaft of each of the tip retaining members 4, and a drive gear 17 to be engaged with the driven gear 9 when each of the tip retaining members 4 stops at its position opposite to the body of the mechanical pencil, is arranged at a specified position. In addition, the drive gear 17 is set afloat on a drive shaft 14 with a specified gap part 19 formed between the drive shaft 14 and the drive gear 17, then tapered faces 20, 21 are formed on the outer peripheral part on one of the lateral sides of the gap part 19 and a press plate 22 which presses the tapered faces 20, 21 are caused to press the tapered faces 20, 21 of the drive gear 17 with the help of a spring 23.  Thus the drive gear 17 can move in the axial direction inside the gap part 19 under the pressure contact effects of both tapered faces 20, 21. When the driven gear 9 rotates to come into contact with the drive gear 17, the driven gear 9 moves the drive gear 17 loosely in the axial direction inside the gap part 19, so that the whole device slides forward/backward, and the rotary disc is caused to rotate sequentially into one direction. Consequently, the tip is sequentially screwed into the body which is sequentially supplied to a specified position, while the tip rotates.

Abstract: PROBLEM TO BE SOLVED: To cast a thin strip by providing a dam between a tank to feed the molten metal in an injector and the injector, and opening the dam when the level of the molten metal in the tank reaches the prescribed value. SOLUTION: Injectors 15, 16 and a roll 51 of a casting machine are preheated. The injectors 15, 16 are moved. The clearance between the tip of the injectors 15, 16 and the roll 51 is measured by a position sensor 42, and the clearance is kept to 0.1-0.5mm. When the level of the molten metal in the tank 11 reaches the prescribed value, a dam 14 between the injectors 15, 16 and the tank 11 is opened, and the molten metal is fed to the injectors 15, 16 to start the continuous casting. The level of the molten metal in the tank 11 is measured by a level sensor 21 to keep the level of the molten metal in the tank 11 at the constant value by adjusting a working device 22 by a regulator 23.

Title: Phase synchronizing device
Inventor: KAWAHARA ISAO
IPC: H04N19/82
Filed: 1988-09-02
Abstract: PURPOSE:To perform excellent acquisition of synchronism by immediately generating reset pulses by means of the vertical synchronizing signal (FP) detected immediately after the discrimination of out-of-synchronism when the out-of- synchronism is discriminated. CONSTITUTION:The 1st synchronism discrimination circuit 22 detects out-of- synchronism by comparing the detecting timing of an FP contained in input signals with the outputting timing of a vertical counter 12 and discriminates the out-of-synchronism when an asynchronous state continues between the detecting timing and outputting timing for prescribed time. When the circuit 22 discriminates the out-of-synchronism and an FP omission detection circuit 23 judges that frequency of occurrence of FP omission is high and, at the same time, the 2nd synchronism discrimination circuit 24 discriminates the out-of- synchronism, a reset pulse generation circuit 25 immediately generates reset pulses by means of the FP detected immediately after the discrimination. Therefore, an HD phase comparator 6 can properly catch horizontal synchronizing signals and a phase locked loop can be formed by means of the horizontal synchronizing signals, and then, a synchronized state can be acquired.
