Title: Manufacture of air electrode for air battery
Inventor: UIRIAMU MARITSUTO
IPC: H01M12/06
Filed: 1990-11-26
Abstract: PURPOSE:To extend the service life of a battery by dissolving a polymer in an aqueous alcohol under the condition of a high temperature and a natural pressure in a sealed temperature and humidity cylinder, preparing a metastable solution, and processing the polymer after mixing the polymer with a carbon holding catalyst within an hour after the preparation. CONSTITUTION:As a binder to manufacture an active layer 4 of two-layer air electrode used for an air battery, a metastable ethanol water solution of a fluoride hydrophlic polymer, 1-propanol water solution, or 2-propanol water solution is used. The metastable solution is prepared by dissolving a polymer in an aqueous alcohol at a high temperature and a natural pressure in a sealed temperature and humidity cylinder, and the resultant solution is mixed with a carbon holding catalyst in an hour after the solution is prepared. Then, the mixture is processed in a normal method. As a result, a mixture with even combination of resin, activated carbon, and catalyst makes the catalyst particles into a complex effectively, and suppresses a loss of catalyst from the surface of the electrode. Consequently, an electrode with a good and long service life property can be obtained, and the service life of the battery is extended.

Title: Optical measuring device
Inventor: YOKOHAMA KATSUHIKO
IPC: G01N21/15
Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent the inflow of grains and combustion gas into a measurement hole with a small quantity of introduced gas and secure a stable visual field by setting the cross sectional area on the measured section side of a connecting passage between the measurement hole and a measuring device main body smaller than the cross sectional area on the measuring device main body side. SOLUTION: A measurement hole 11b provided on the wall face 11a on the measured section side is communicated with the inside of a container 10 storing a measuring device main body 12 via a passage 11d. The main body 12 in the container 10 conducts the optical measurement of the measured section via the measurement hole 11b. The passage 11d is formed along the shape of an optical path so that its cross sectional area on the measured section side is made smaller than its cross sectional area on the measuring device main body 12 side. The gas flow velocity at the outlet of the passage 11d is accelerated by smaller quantity of introduced gas, and the dust tending to enter the passage 11d can be pushed back by the flow velocity.  The infiltration of grains and combustion gas into the measurement hole 11b is efficiently prevented, a stable visual field can be secured over a long period, and stable high-accuracy optical measurement can be maintained.

Title: Optical sensor apparatus
Inventor: NAKAGAWA SHIRO
IPC: G01V8/12
Filed: 1988-12-22
Abstract: PURPOSE:To prevent the effect of disturbance by adding a light detection circuit including a light emitting element and a photodetector to a duty ratio variable oscillation circuit and detecting a change in the oscillation of duty ratios at the time of the presence and absence of an object to be detected. CONSTITUTION:A small duty pulse oscillation circuit 5 is composed of the combination of a gate circuit G1, a reversal gate circuit G2 and a time constant circuit of a capacitor C1 and resistors R1, R2. The duty ratio of the pulse oscillation output of this circuit 5 is almost determined by R2/R1 and, by making the value or R1 larger than that of R2, the duty ratio can be set, for example, to about 1/10-1/1,000. A light detection circuit 6 has a series circuit consisting of a resistor R10, a light emitting diode LD and a transistor Tr1, and a light source composed of a register R11. By this constitution, when an object 1 to be detected is absent, a phototransistor PTr1 is in an OFF-state and no AC component is added to a level shift circuit 7. When the object 1 to be detected is present, the light emitted from the diode LD is reflected from the object 1 to be detected to be incident on a transistor PTr1 and a cyclical pulse signal appears to be amplified to be applied to the circuit 7.

IPC: F23D14/02
Filed: 1990-11-26
Abstract: PURPOSE:To provide a stable combustion for the flame that is shortened and suppress the generation of CO by providing opposite to the internal end section of the burner duct of a supply air pipe, a rotating guide body that leads out the combustion air into the burner duct. CONSTITUTION:The combustion air is once throttled by a throttling section 9a provided in a supply air pipe 9 and guided into a rotating guide body 30. Here, it collides with the central section of an opposing disc 31 and is dispersed circumferentially. And it is led out into a burner duct 6 from the gaps among many rotating vanes 33. Since each of the rotating vanes 33 is curved by the same radius of curvature and they are tilted mutually, the combustion air that is led out among those vanes 33 forms uniform rotating flows along all the circumference. The combustion air fills, therefore, uniformly in the inside of the burner duct 6, and it is supplied in a stable state from between a gas nozzle 21 and a throat 20 to a premixing chamber 19, and, at the same time, it is also supplied stably to secondary flame ports 13....

CONSTITUTION:A photomask 30 is selectively provided with a chrome film, for example, as a light shading material on a quartz glass substrate 31, for example, as a light shading substrate, a light shading part 33 is constituted at a part where the chrome film is provided and a light transmission part 35 is constituted at a part where the chrome film is not provided, and simultaneously, there is a recessed part 35a formed by way of removing a part of the glass substrate itself at a part corresponding to the light transmission part 35 of the glass substrate 31 and a recessed part 35a of a depth t2 enough to make the light shading part 33 to be protruded enough to stick it to a non-exposed scheduled territory of a resist membrane. In this case, the light shading part 33 is protruded enough to make contact with a part to make a non-exposed part of a resist recessed part. Consequently, it is possible to secure favourable sticking of both of them.

Title: Range-finding device for camera
Inventor: SAITO HIROYUKI
IPC: G01C3/06
Filed: 1993-12-21
Abstract: PURPOSE:To rapidly perform the operation from starting light projection to the focusing of a photographing lens by deciding the gain of an amplifier circuit by performing preliminary light emission in the case of amplifying an optical signal from a subject, easily obtaining a subject distance from the decided gain, and focusing the photographing lens without starting normal light emission. CONSTITUTION:When a range-finding routine is started, the power sources of all the circuits are turned on, first. Next, a CPU 80 clears the contents of a storage device (RAM) 81 capable of reading/writing, and decides the optimum gains of the amplifier circuits 40 and 50. The gain is decided by the preliminary light emission. In the case of deciding that the subject is at a position within a certain distance while performing operation for deciding the gain, it is judged as being the closest without performing range-finding because a closest flag in the RAM 81 is set. Since values S1 and S2 are decided while performing the operation for deciding the gain, a lens barrel 86 is driven based on the moving amount of the photographing lens stored at the address of a ROM 82 univocally decided from the values.

Abstract: PURPOSE:To evade a read error at the time of read operation due to misalignment of a head with a cylinder on a disk and also read infeasibility at the time of the read operation after information is written under the misalignment state deviated from a correct cylinder position at the time of write operation and hence to improve the reliability of an information system by controlling a read and write control circuit and stopping read and write on the disk when the temp. of a disk enclosure exceeds a prescribed temp. CONSTITUTION:When the ambient temp. of the disk storage device exceeds its operational condition due to trouble of a cooling fan, a detected temp. of a temp. sensor 110 is compared with a preset value by a comparing circuit 111, and upon excess of the detected temp. over the preset value, a write inhibit instruction signal is outputted to the read and write control circuit 102, and the read and write head 106 is inhibited from its driving. Then, since a signal showing temp. abnormality is also outputted from the comparing circuit 111 to a control circuit 101, the temp. abnormality in read-out from a host device H can be advised.
