IPC: G01N25/20
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To accurately measure a specific heat capacity, by calculating a thermal capacity of a sample by using a specific formula from temperature differences of a circumferential object from a sample side heat sensitive plate and reference substance side heat sensitive plate, thereby reducing number of times of measurements.

Title: Input circuit
Inventor: KUSANO TAKAO
IPC: H03K3/037
Filed: 1988-09-27
Abstract: PURPOSE:To synchronize an input signal inputted asynchronizingly without propagating an intermediate potential to the inside by controlling a latch circuit for a signal with an output of the circuit detecting it that the signal is at an intermediate potential. CONSTITUTION:An input signal of a buffer 16 is a signal corresponding to a point A of a current load characteristic of MOSFETs 14, 15 and an output of the buffer 16 reaches logic '1' in terms of the positive logic. Since the output is ORed with, etc., a clock, the inverse of phi as a reset input of a D latch circuit 2, the D latch circuit 2 is in the reset state while an output of a D latch circuit 1 is in the intermediate potential, the intermediate potential is not propagated in the inside. Thus, the propagation of the intermediate potential into the inside is prevented by resetting the D-latch circuit 2 when the output of the D latch circuit 1 reaches an intermediate potential in this way.

Title: Regeneration of hydrated catalyst
Inventor: TEZUKA MAKOTO
IPC: B01J38/64
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To provide a method by which the regeneration rate is increased and the deterioration of the catalytic activity is minimized for a long time, if the regeneration is repeated by specifying each of the treatment temperatures, in a method for catalytically treating zeolite used for chemical reaction with gas containing a molecule-state oxygen after its catalytic treatment with nitrogen when regenerating the zeolite. SOLUTION: When regenerating zeolite used for liquid phase hydration reaction of olefin using a zeolite catalyst, the zeolite is catalytically treated with a gas containing a molecule-state oxygen at 400 deg.C or higher after catalytic treatment with nitrogen at 80-500 deg.C. If the zeolite is thermally treated under a nitrogen gas atmosphere, the decomposition and desorption reactions of an organic matter on the zeolite presumably take place preferentially by an action at a melting point of the zeolite. Consequently, it is presumed that most of the organic matter on the catalyst wound be removed without a caulking phenomenon such as polymerization. Further, it is presumed that the organic matter wound be completely removed without changing the struction and the nature of activity point of the catalyst by catalytically treating the zeolite with the gas containing the molecule-state oxygen after reducing the amount of the organic matter.

Filed: 1999-08-30
Abstract: PROBLEM TO BE SOLVED: To execute interference check in a short time and with precision by confirming whether the same space area exists or not in a three-dimensional shape in a moving space when plural matters move on the same coordinate systems so as to judge an interfering relation. SOLUTION: Plural pieces of three-dimensional data are read from a storing device 20 and stored in a RAM 15. Positional data on respective three- dimensional shapes moving on a coordinate system are inputted and recorded in a RAM 16. A moving shape preparing arithmetic part 1 newly prepares a three-dimensional shape obtained by combining the respective three-dimensional shapes before/after moving which are stored in the RAM 15 along a moving locus. A shape overlapping part arithmetic part 3 calculates the three- dimensional shape of overlapping part of the respective newly prepared three- dimensional shapes to be stored in a RAM 17. A shape overlapping part judging part 4 judges the presence/absence of the overlapping part of the newly prepared three-dimensional shapes. Then, when there is not an overlapping part, it can be judged that no interference occurs.
