Title: Shock absorber
Inventor: NAKAI MASASHI
IPC: F16F9/10
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To obtain a shock absorber excellent in reliability by inserting an accumulator formed endlessly between a pair of flanges having a rod guide formed in a nearly spool shape. SOLUTION: An accumulator 14 formed endlessly is inserted between a pair of flanges 12, 13 having a rod guide 9 formed in a nearly spool shape. Therefore, this is different from the accumulator formed in a shape with an end and has no divided places. So, such inconvenience as the one stick out part of the accumulator 14 through a notch 23 is hardly generated. As plural notchs 23 are formed on a rear side flange 12, the sectional area of an individual flow passage can be set small in comparison with the constitution in which only one notch 23 is formed. Therefore, such inconvenience as the one stick out part of the accumulator 14 is hardly generated. Therefore, by that the said two actions are performed multiplicatively, a shock absorber excellent in reliability extremely can be realized.

Abstract: PROBLEM TO BE SOLVED: To provide a cup supply device which can construct a cup supply means of a simple structure. SOLUTION: When a turntable 52 is revolved by a motor 53 of a cup train supply mechanism, a roller 52a of the turntable 52 touches the shaft 51a of a depressing plate 51 and the plate 51 revolves in the cup train push-out direction.

In other words, the plate 51 rocks by the revolution of the turntable 52 and has a reciprocating motion per revolution of the turntable 52. In such a constitution, the cup train supply mechanism is simplified.

Abstract: PURPOSE: To improve the vertical resolution in a surface sequential electron endoscope device by driving a device by shifting the start phase of the scanning in a vertical direction for every field by 1/2Hs and making the device perform an interlace operation. CONSTITUTION: This device is composed of R, G and B memories 18, 20 and 22 in which writings are controlled by the direct enable pulses of an enable pulse generator 16 and R', G' and B, memories 19, 21 and 23 in which writings are controlled by the enable puls es delayed by three fields by a three-field delay circuit 17. Therefore, when the R memory 18 is an odd-numbered field at first, for instance, the video signal of an even-numbered field is stored in the R' memory 19 after the three fields of the R memory 18. Because a R signal adds the reading output of the R memory 18 and the reading output of the R' memory 19 by 1/2s in level in an adder 24 from this relation, the video signal for interlace in which the odd-numbered field and even-numbered field signals are added is obtained.
