Patent JP-H0297899-A (JP)
Title: Heat exchanger
Inventor: YAMADA ARITAKA
IPC: F28F1/40
Filed: 1988-09-30
Abstract: PURPOSE:To prevent the deterioration of heat transfer performance due to the biased flow of refrigerant by a method wherein a hollow spiral plate, provided with a dam at the end thereof, is inserted into a heat transfer tube positioned at upstream side connected to the inlet port of the inflow tube of a flow distributor. CONSTITUTION:A hollow spiral plate 15, provided with a dam 21 at the end thereof, is inserted into a inflow heat transfer tube 14. According to this constitution, liquid phase B2 among the flows of refrigerant B, flowing through the inflow heat transfer tube 14 and separated into gas phase and liquid phase, is made to flow spirally along the inner surface of the heat transfer tube 14 by the hollow spiral plate 15 to prevent the flow of the same biased to the trough of the spiral part while the gas phase B1 of the refrigerant R is made to flow through the hollow part of the spiral plate 15 to accelerate it. The mixing of the gas phase with the liquid phase B2 on the inner surface of the tube is promoted by the extracting effect of the gas phase B1 accelerated by the dam 21 to restrain the adhesion of the refrigerant B to the wall surface of a branching section 26 and prevent the excessive flow of the liquid phase B2, heavier than the gas phase B1, into a lower outflow tube 24b by the affection of a gravity whereby the uniform distribution of the flow may be effected. On the other hand, the inner surface of the tube is covered at all times by the liquid phase B2, in which boiling heat transfer is generated, whereby the heat transfer coefficient of a heat exchanger may be improved.

Title: X-ray stress measuring instrument for plural phase metal
Inventor: SEKIGUCHI HARUO
IPC: G01L1/00
Filed: 1987-09-30
Abstract: PURPOSE:To improve the measuring accuracy by installing an X-ray generator and an X-ray detector so as to be movable relatively in a sample placing base and setting the X-ray detector so as to become smaller in angle than that of the X-ray generator against a normal of the sample placing base. CONSTITUTION:When a plate-like sample consisting of two phases is set onto a sample placing base 4 and a device is operated, an X-ray generator 2 turns, and X rays are radiated to the sample at a prescribed incident angle psi1. As a result, diffraction rays are generated from the phase which coincides with the incident angle psi1 and made incident on an X-ray detector 3. In such state, the detector 3 detects the diffraction intensity from a first phase, and its diffraction ray profile is outputted to a storage circuit 6. Subsequently, the generator 2 is turned against a sample normal N, set to a position corresponding to a second phase, and by oscillating the detector 3, the profile of the second phase is measured. In such a case, the detector 3 is positioned at a nearer position than that of the generator to the normal N, therefore, the detector 3 detects the diffraction rays without being screened by the sample, its profile is stored 6, and thereafter, an average stress is calculated by an arithmetic circuit 7.

Thereby, although the signal S1 for the entry of the foreign materials is temporarily generated from the sensing circuit 1, the signal does not continue. The operation stop signal S2 is not outputted from the control circuit 3 corresponding to the signal S1.

IPC: H01H49/00
Filed: 1989-09-26
Abstract: PURPOSE:To make it possible to detect the magnetic attracting force of a magnetic pole readily by providing a pressure sensor which compresses an armature or a card that is formed of an armature as a unitary body, and providing a driving mechanism which automatically moves the pressure sensor back and forth. CONSTITUTION:When an electromagnetic relay is not driven, the free end of an armature 3 is attracted to the side of an auxiliary magnetic pole 15, and a movable contact 24 is in contact with a fixed contact 25 on the break side. Under this state, a contactor 61 of a pressure sensor 6 is made to face the side surface of a card 31. When a motor 73 of a driving mechanism 7 is operated, a cam mechanism 72 is rotated. A specified signal is outputted from the sensor 6 in correspondence with the steady state and then non-steady state of the electromagnetic relay. The signal outputted from the sensor 6 corresponds to the force applied on the contactor 61. The peak value when the contactor 3 is separated from the auxiliary magnetic pole 15 is measured. Then the magnetic attracting force which brings the contact 24 into contact with the contact 25 on the break side can be readily detected. When the peak value as the armature 3 is separated from a main magnetic pole 13 is measured by the same way, the magnetic attracting force which brings the contact 24 to a fixed contact 26 on the make side can be readily detected.
