Title: Screw structure having resistance to fatigue
Inventor: SUGIMURA NOBUYUKI
IPC: F16B33/04
Filed: 1990-11-01
Abstract: PURPOSE:To prevent generation of stress concentration in a screw structure wherein a male screw is screwed width a female screw by expanding deformation span while providing at least one of the screws with a screw thread having a plate-like longitudinal sectional shape. CONSTITUTION:A thread screw 11 of a male screw 10 is formed substantially trapezoidally at its section. Run-off parts 12, 12' are formed so as to easily deform a thread screw 16 of a female screw 15. The thread screw 16 of the female screw 15 has plate-like form at its longitudinal section. The height H of the thread screw 16 is formed higher than the normal one, and higher than height (h) of the male screw 10. Width D of a top 15a of the female screw 15 is set narrower than width (d) of a top 10a of the thread screw 11 of the male screw. When a load is applied to the male screw 10, the female screw 15 receives compression load and is deformed. The female screw 15 is easily deformed because the deformation span at this time is extremely long. The load applied to every unit length of the thread screw is small, and stress concentration is not generated.

Abstract: PURPOSE:To provide an ink-jet printer which avoids ink from being infiltrated into a negative pressure-generating means when ink is sucked through the nozzle of an ink-jet head by the negative pressure-generating means. CONSTITUTION:A capping means for covering the nozzle of an ink-jet head with a cap is provided. An air discharge port 38 connected to the air suction port of a negative pressure-generating means is formed to the upper part of a waste ink reservoir 25 having an ink suction port 37 connected to the cap.

Title: Discriminating device for paper or the like
Inventor: MIZOI YOICHI
IPC: G07D7/00
Filed: 1993-10-29
Abstract: PURPOSE:To securely decide the extraction of paper or the like which is re ceived once without being affected by an external noise by comparing the count value of the number of pulse signals of a pulse signal generation part with a previously set reference number after deciding that the thrown-in paper or the like, is genuine through discriminating operation. CONSTITUTION:When a bill is conveyed up to the position of a magnetic sensor 7, the magnetic sensor 7 detects a detection signal and outputs it to a CPU 11. The CPU 11 decides whether or not the width of the bill is proper, from the passage signal of a passage sensor 6 and discriminates whether or not the pattern of the bill is proper, from the pulse signal of the pulse generation part 13. When the bill is discriminated as a proper bill, the CPU 11 wakes a conveyor belt to travel to convey the bill in the direction to a bill safe and to preserve temporarily in a preserving position. Once the vending of an articles is completed by an automatic vending machine, the CPU 11 outputs a driving signal to a motor 16 for bill storage on the basis of a bill storage instruction to store the bill in the bill safe. When the bill is discriminated as a false bill, on the other hand, a reverse driving signal is outputted to the motor 15 for bill conveyance to return the bill to a bill throw-in opening.
