Abstract: A PCI-PCI bridge which connects a primary PCI (Peripheral Component Interconnect) bus and a secondary PCI bus comprises two physically different controllers, a primary PCI serial transfer controller located on a PC (Personal Computer) body side and a secondary PCI serial transfer controller located on a docking station side. Both controllers are connected together by serial LVDS (Low Voltage Differential Signal) lines, and data needed to transfer a bus cycle is serially transferred between both controllers. An interrupt signal generated on the docking station side is serially transferred to the primary PCI serial transfer controller from the secondary PCI serial transfer controller via the serial LVDS lines for transferring data in a bus cycle.

Abstract: An automatic humidity step control thermal analysis apparatus has a detector for detecting and measuring a physical property of a sample and for generating a physical property signal corresponding to the physical property of the sample. The sample is housed in a sample chamber which is capable of controlling the temperature and humidity of the sample. A water chamber generates water vapor at a preselected temperature and is capable of controlling the temperature of water in the water chamber in a stepwise manner. A heat insulating pipe directs water vapor from the water chamber to the sample chamber and includes a heater for preventing dew condensation. A signal stability determination circuit receives a physical property signal from the detector and generates a trigger signal when a rate of change of the physical property signal drops below a preselected reference value.

Abstract: In this invention, the bus of a computer body is connected to the bus of an expansion unit through a serial interface so as to implement connection wirings in the form of a serial cable. A PCI-PCI bridge for connecting a primary PCI bus to a secondary PCI bus comprises two physically isolated controllers, i.e., a primary PCI serial transfer controller implemented on the PC body side and a secondary PCI serial transfer controller implemented on the docking station side. The two controllers are connected to each other through serial LVDS lines. Transactions are exchanged between the primary PCI bus and the secondary PCI bus by serial transfer between the primary PCI serial transfer controller and the secondary PCI serial transfer controller.

Abstract: In this invention, serial transmission suitable for signal lines in which a transformer is inserted is realized by using existing differential buffers. Differential output buffers are connected in parallel with each other. A differential signal line pair in which a transformer is inserted is driven by these two differential output buffers. In this case, a voltage between the two lines of the differential signal line pair is determined by a combination of outputs from the two differential output buffers, and three values, i.e., “+V”, “−V”, and “zero”, can be output. By using this ternary data, serial signal transmission based on the bipolar transfer mode can be performed, and serial transmission suitable for the signal lines in which the transformer is inserted can be realized.

Abstract: The sample temperature is roughly controlled according to a program temperature by a furnace temperature controller, and at the same time precisely controlled by a detector temperature controller. Also, if a temperature difference occurs, the supply powers to heaters separately provided close to the sample and reference are adjusted such that the temperature difference is returned to zero by a differential heat compensating circuit, outputting a difference in supply power as a differential heat flow.

Abstract: An insulating substrate provided with two types of metallic or alloy circuit patterns for detecting temperature difference between a sample side and a reference side, and also a metallic resistance circuit pattern, is fixed to a heat sink, and the heat sink is temperature controlled. If a temperature difference between the sample and the reference is detected, electrical power supplied to a compensation heater using metallic resistors is adjusted by a differential heat compensation circuit so that the temperature difference is immediately returned to zero, and a difference in supplied power is output as a differential heat flow.

Abstract: Humidity dependency of a physical property of the sample is evaluated while introducing the saturated vapor corresponding to the wet-bulb temperature into the sample chamber in which the temperature is controlled corresponding to the dry-bulb temperature of the wet-and dry-bulb type hygrometer. At this point, by changing the temperature corresponding to the wet-bulb temperature at the timing when physical property signals of the sample become stable, the different saturated vapor is introduced into the sample chamber, then the humidity of the sample chamber is automatically changed in a stepwise manner. The humidity of the sample chamber is always changed after the physical properties of the sample becomes stable, so that the knowledge about the time required for the sample to reach the equilibrium state is not necessary, and humidity dependency of physical properties of the sample can be measured accurately.

Abstract: A heat flux type differential scanning calorimeter has a heat reservoir made of a thermal conducting material. A thermally conductive plate is disposed in the heat reservoir for supporting an unknown sample and a reference sample symmetrically with respect to a center of the reservoir. A thermally conductive support member is disposed in contact with the thermally conductive plate and supports the thermally conductive plate in the heat reservoir. A heat buffer plate is disposed between the thermally conductive support member and the heat reservoir so that the thermally conductive support member and the heat reservoir are contacted only through the heat buffer plate.

Abstract: Under a same heating condition as a sample to be measured, a physical property is measured for a reference substance whose temperature dependency of a physical property value is previously known. Reversely, a temperature profile of the reference substance is read so that the temperature profile is applied to a physical property measurement result for the sample. Thus, thermal analysis for the large diameter sample is made accurately without the necessity of arranging a temperature sensor in the vicinity of the sample.

Abstract: In bending type or shearing type dynamic viscoelasticity measurement, a static stress adjuster adjusts static stress to zero in order to effectively eliminate static stress caused by influences such as warp caused by thermal expansion of a specimen or residual stress, for instance. Further, a static distortion adjuster adjusts a varying speed of static distortion to zero in order to suppress an increase of the static distortion and prevent the specimen from being excessively distorted even when the specimen is soft and has little restoring force. A dynamic viscoelasticity measuring system includes the static distortion adjuster for adjusting the static distortion of the specimen and the static stress adjuster for adjusting the static stress of the specimen, and measures the viscoelasticity of the specimen by selective operation or cooperation of the static distortion adjuster and the static stress adjuster depending upon quality change of the specimen being measured.

Abstract: A viscoelasticity measurement instrument having a support whose position can be varied relative to a sample holder for holding an end portion of a sample. A detection rod is resiliently held to the support, and holds a part of the sample. When a DC or AC force is applied to the detection rod, the displacement of the detection rod relative to the support is detected. The position of the support is varied or the DC force is varied to restore the displacement to zero. In this manner, the effect of the elastic constant of the support is eliminated. In one embodiment, a detection rod is support by leaf springs. Negative feedback control is utilized to return deformation of the leaf springs to zero at all times to eliminate the spring constant effect of the leaf springs. Since the average displacement of the leaf springs is zero, the positional relation between the permanent magnet and the coil forming the electromagnetic force generator varies negligibly.
