Title: Reduction of viologen derivative
Inventor: NEZU TETSUYA
IPC: C07D213/02
Filed: 1992-07-28
Abstract: PURPOSE:To efficiently reduce a viologen derivative having a photosensitizing benzophenone structure bonded to a viologen skeleton by using visible light or a chemical reducing agent. CONSTITUTION:A viologen derivative of formula I (X is Cl or ClO4) can be reduced in high efficiency by using visible light or a chemical reducing agent. For example, 1mol of the viologen derivative of formula I is dissolved in 10<6> to 10<3>mol of a solvent containing 1-100% of a reducing agent and irradiated with a UV-cut xenon lamp for 10min to 3hr. As an alternative, the viologen derivative of formula 1 is reduced by adding 1-5 equivalent of a chemical reducing agent (e.g. metallic sodium or sodium dithionite) to l equivalent of the compound of formula I. A one-electron reduction product of formula II can be produced by this process. Since reduction product of viologens has clear color, it can be applied to photosensitive material, electro-sensitive display material, oxidation-reduction mediator and various sensors.

Title: Method for diagnosing partial discharge of gas insulation device
Inventor: IWAASA SHUZO
IPC: G01R31/12
Filed: 1988-09-07
Abstract: PURPOSE:To diagnose a location and a cause of failure by measuring magnitude of change in partial discharge electric load corresponding to change in applied voltage of an insulation device and magnitude of electrification of partial discharge. CONSTITUTION:When metallic lines 50 to 53 are mixed into a grounding tank 30, or a crack 60 is made on a spacer 40, partial discharge occurs at the tip of the metallic lines 50 to 53 and the crack 60 with high voltage applied to a high voltage conductor 20, and it is detected by a partial discharge detector 1. Since the applied high voltage is ac current, voltage in a peak value range can be selected. This permits partial discharged electric load C with respect to instantaneous values of voltage at several points to be measured 2. Instantane ously applied voltage can be also measured. Since the relation between the applied voltage and the electric charge C differs depending on the conditions, with these characteristics input in a computer 3, detailed conditions of a failure can be diagnosed by identifying which characteristics are applicable if data measured by a measurement device 2 is acquired in the computer 3.

Abstract: PURPOSE:To non-destructively and simply detect whether a local color shade on the surface of a magnetic recording medium, and a change of a coefficient of friction, etc. exist or not, by measuring the heat radiation quantity from the surface of said medium which is heated by a heating device, and also, rotated, by a heat radiation measuring instrument. CONSTITUTION:In a state that a magnetic recording medium having a gamma-Fe2O3 magnetic film, installed in a rotary mechanism 21 is rotated by, for instance, scores of gammapm, its surface is heated within a prescribed temperature range by a line heater, and a surface temperature of the medium 24 is measured by an infrared-ray detector 23. A local color shade part 25 on the surface of this medium 24 has a larger thermal absorption than other part, therefore, since its color shade part has a larger thermal absorption than other part, its surface temperature is high, and its heat radiation quantity is large, therefore, whether the local color shade part 25 exists or not can be detected easily. Also, from a data by which as for a color shade part in which the heat radiation quantity is large in advance, a coefficient of friction is low, and as for a part in which the heat radiation quantity is small, the coefficient of friction is high, a fluctuation of the coefficient of friction can be detected non-destructively and simply.

Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To visually and tactually recognize the contents of a map by providing actuators on sliding pins, driving the actuators and expressing projection and recession by the height differences of the pins projected form the same surface. SOLUTION: A display device is constituted that lots of sliding pins 22 are arranged in a matrix manner as a projecting and recessing display section 14. The length of the projections (the amounts of displacement) of the pins 22 are adjusted by actuators 20. By driving the actuators 20, the projection and the recession are expressed by the height differences of the pins 22. That is, point data are converted into the address data of the section 14 and the height information of the point are given as the amount of displacement of the pin 22. Therefore, if the height data of each point are converted into the projecting length of the pin 22, a specific topography is expressed on a two dimensional display surface as the projection and the recession of the pins 22, in other words as the height differences from the display surface which is a reference surface.

Inventor: KAWASE OSAMU
IPC: H01R13/42
Filed: 1996-08-23
Abstract: PROBLEM TO BE SOLVED: To move a terminal in a half-inserted state to the regular inserted position when a retainer is to be displaced to the original engagement position. SOLUTION: A retainer 30 is furnished with a guide slope 35 for a deflecting detent piece, and a female terminal 20 is equipped with a guide slope 23B for terminal. If the retainer 30 is displaced to the original engagement position when the female terminal 20 is in the half-inserted state, the guide slope 35 is detained with the detent piece 14 which is thus deflected upward, and therewith the female terminal 20 is pushed into the regular position by the tilt of the slope 35. This liberates the operator from troublesomeness to make re- insertion in case the female terminal 20 remains half inserted.

IPC: G06F11/34
Filed: 1987-09-08
Abstract: PURPOSE:To facilitate the analysis for the factor of a hang-up phenomenon, by resetting a trace control means starting FF and an MPU with a 1st resetting signal in a hang-up state to track the contents of a trace information memory means and transmitting a 2nd resetting signal. CONSTITUTION:In a normal state a trace control circuit 2 is started by a trace start setting signal S0 via an FF 4. Then the write signal W1 received from the circuit 2 is stored in a trace information memory part 5 by the bus cycle start signal S1 received from an MPU. At the same time, the trace information is stored in the part 5 by an instruction given from an address production circuit 3. Then the hang-up informing signal Sh received from the MPU is detected by a reset production circuit 1'. Thus a back-up resetting signal Sa is sent to the CPU and the FF 4 for resetting them. Thus it is possible to hold the contents and the address of a register of the circuit 2 and to read out the contents of the part 5 via the MPU whose hang-up state is released.

It is judged whether or not a representative pattern having only a branch to a pattern whose mark is eliminated exists (S14). One representative pattern having only a branch to the pattern whose mark is eliminated is extracted and is defined as (p) (S15). The matching with respect to the pattern (p) in the node (v) is found (S16) and whether the matching is met or not is judged (S17). And, the matching with respect to a similar pattern is found by using a conversion map (S18).
