Title: Method of evaluating performance of heat pump using hydrogen-occluding alloy
Inventor: HASHIMOTO TAKUYA
IPC: F25B17/12
Filed: 2000-03-24
Abstract: PROBLEM TO BE SOLVED: To estimate the performance of a heat pump using hydrogen-occluding alloy with high accuracy. SOLUTION: A hydrogen absorption and discharge cycle is repeated for hydrogen- occluding alloy to be filled in a heat pump is repeated to measure the hydrogenation equilibrium characteristics after passage of cycle four times or more. As regards the hydrogenation equilibrium characteristics property where the dependency on cycle is confirmed, the estimate of the change of the hydrogenation equilibrium characteristics which will occur when the hydrogen absorption and discharge cycle is repeated in the hydrogen-occluding alloy filled in the heat pump is performed, based on the estimate formula consisting of an exponential function whose variables are the change of the hydrogenation equilibrium characteristics and the number of times of repetition of the hydrogen absorption and discharge cycle, or a linear function, or a function where these are combined.  This estimate formula is made by applying approximation operation, based on the data measured four times or more. The change of the hydrogenation equilibrium characteristics is estimated, based on this estimate formula, and the performance of the heat pump is evaluated, based on the estimate result.

Title: Scanning probe microscope
Inventor: NAKAMOTO KEIICHI
IPC: G01B21/30
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a scanning probe microscope allowing accurate positioning of laser light onto a cantilever, in the case of any sample. SOLUTION: In this scanning probe microscope, illumination light generated from an optical microscope 7, reflected by a beam splitter 13 and a mirror 21 and transmitted through a half mirror 22, is irradiated obliquely on the rear face of the cantilever 14 and is incident obliquely on a sample face. Because the rear face of the cantilever 14 is formed in a mirror surface, most of the illumination light irradiated on the cantilever 14 is reflected regularly toward the optical microscope 7, shown as B in Figure. Of the regularly reflected light, light transmitted through the beam splitter 13 and a filter 12, condensed by a condenser lens 10 and transmitted through a half mirror 9 reaches a CCD camera 11. As a result, even if the sample has low reflectance to the illumination light, an image with contrast of the cantilever 14 rear face is formed on the CCD camera 11.

Title: Data communication system and recording medium recording data communication program
Inventor: NAKAGAWA ITARU
IPC: H04L12/46
Filed: 2000-04-14
Abstract: PROBLEM TO BE SOLVED: To quickly restart data communication after re-establishment of a data link and after recovery from an increased delay and to enhance the efficiency of data communication by earlier recovery from slow start and congestion suppression control, after a restart of communication. SOLUTION: A communication control program 1C and a communication control program 1A store a copy of communication contents at all times during data communication. When interrupts and delays in a data link are increased, a communication control program 1C transmits a transmission stop instruction to its own application program 2B to temporarily interrupt data transmission. After the recovery of interrupt of the data link, the copy of data communication contents is sent to an opposite application program 2A and when an acknowledgement is received from an opposite side, the application program 2A generates acknowledgement packets, on the basis of it and transmits them to its own application program. Thus, the system is early recovered from slow start and congestion suppression control.
