Title: Constant humidity device using aqueous solution with saturated salt
Inventor: FURUICHI AKIO
IPC: G01N1/00
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To find out the correct relative humidity of the gas contained in a sealed container even when the gas of the container and the saturated aqueous solution have different temperatures and are not balanced with each other by adding a means into the container to measure the temperatures of both gas and saturated aqueous solution. SOLUTION: The saturated aqueous solution 2 of sodium chloride is surely saturated since the solid contents of sodium chloride remain. Then the temperatures of the gas and the solution 2 are measured by the platinum temperature detectors 3 and 4. The detector 3 is placed near a humidity sensor 5. Thus, it is possible to decide the saturated vapor pressure from the gas temperature, to decide the vapor pressure from the temperature of the solution 2 and then decide the relative humidity from both saturated vapor pressure and vapor pressure even when the gas and the solution 2 have different temperatures in a sealed container and accordingly are not balanced with each other. As a result, a constant humidity device using the solution 2 of sodium chloride can be used even in a normal environment without using any constant temperature oven nor chamber. In addition, the quick measurement or test is attached since it's not required to wait for a balanced state secured between the gas and the solution 2.

Inventor: CHOKAI MASAYUKI
IPC: F16D3/84
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To secure reliability of sealing ability in a seal part even in the case where wide angle deformation is made by forming a sealing projection on the inner peripheral surface sides of large diameter and small diameter both end short cylindrical parts, and forming a groove, the dimensions of which are specified, on the outer peripheral surface side of the width central area in the axial direction of the joint boot. SOLUTION: This joint boot is so constructed that the diameter of a bellows is gradually decreased from the large diameter bore end to the small diameter bore end. A circumferential groove 92 positioned on the outer peripheral surface side of a portion where a sealing projection 91 is formed is such that the width dimension (a) is equal to or larger than the depth dimension (b). The sealing projection 91 is provided not doubly, but singly. The projection height of the sealing projection 91 is one to two times as large as the thickness of the joint boot in a portion adjacent to the sealing projection 91. On the other hand, the depth size of the groove 29 is one to one and a half times as large as the thickness of the joint boot in a portion adjacent to the sealing projection 91. Thus, satisfactory sealing ability can be secured without any increase in fastening force.

Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by detecting changes of an address signal, outputting a detection signal, comparing the detected signal with a clock signal, generating a pre-charge signal and pre-charging only a prescribed address. SOLUTION: When an address signal 607 is changed, an ATD detection output signal from an address transition detection(ATD) circuit 602 is changed to high level to be transmitted to a comparison circuit 603. Although the signal 604 is compared with the clock signal in the comparison circuit 603, since the clock signal is at low level, the pre-charge signal is at high level, and does not stilt to pre-charge operation. When the clock signal is changed to high level, the pre-charge signal is changed to low level, and moves to the pre-charge operation. When the time becomes a memory access period, the ATD detection output signal is reset by the clock signal supplied to the ATD circuit 602 to be changed to the low level, and simultaneously, the pre-charge signal is changed to the high level also, and the pre-charge operation is ended.
