The Pd salt in this case is used in the form of an aq. soln., and the amt. of the Pd salt to be added is adjusted to the extent at which the pulverized powder of the metallic Cr becomes muddy when said salt is added and both are kneaded. The amt. of the Pd salt to be used with respect to the metallic Cr is preferably 0.5-2.5wt% in terms of the metallic Cr. The pulverized powder of the metallic Cr impregnated with the Pd salt is dried by heating at 80-90 deg.C and is compacted under 100-400kg/mm.<2> molding pressure. The green compact is subjected to a primary sintering at 700-900 deg.C followed by a secondary sintering at 1,000-1,400 deg.C, whereby the intended activated metallic Cr is obtd. The sintering is accomplished in an inert atmosphere of Ar, He, etc. or in an H2 atmosphere.

Title: Inspecting device for micro-unevenness on surface
Inventor: KATSUYAMA MINORU
IPC: G01B11/30
Filed: 1981-10-12
Abstract: PURPOSE:To enable to perform the detection of micro-unevenness on an object to be inspected and to permit the observation of the whole surface of the object to be inspected at one time, by diffusing and collecting light from a light source by means of a concave mirror. CONSTITUTION:Light, which is emitted from a light source 1 and passes through a pin hole 2, is reflected by a first concave mirror to produce diffusion light with which a mirror-surfacelike object 3 to be inspected is irradiated. After light reflected by the object 3 to be inspected is collected by a second concave mirror 9, light is collected by a third concave mirror 10, and an image is formed on a light receiving surface 4. In case a concavity 5 is formed in the object 3 to be inspected, the concavity 5 performs the same function as that of the concave mirror, and light from the light source 1 is scattered. Thus, light is reflected from the object 3 to be inspected in conformity with a change in luminous intensivity. Thus, from a change in illuminance distribution of reflected light, a condition of the surface of the object to be inspected can be inspected in a non-contact manner.

Title: Hydrogen shielded-type arc welding method
Inventor: SAKAI YOSHIYA
IPC: B23K9/00
Filed: 1987-06-30
Abstract: PURPOSE:To prevent the occurrence of a pit, a blowhole, a gas groove, etc., in the arc welding such as the fillet welding, etc., regardless of the presence or absence of the application of primer to the surface of objects to be welded by specifying the quantity of hydrogen in a flux-cored wire. CONSTITUTION:A wire containing hydrogen >=100ppm therein is used as the flux-cored wire and the welding is performed without using shielding gas from the outside. The hydrogen in said wire has two effects, namely, the stirring effect to accelerate to exhaust gas in weld metal and the shielding effect to protect molten metal from nitrogen and oxygen in the air after the gas is exhausted from the molten metal. In order to display both effects fully, the hydrogen in the wire is necessitated to contain >=100ppm therein and the pit and blowhole cannot be checked to the minimum and in addition, the lack of shielding is caused with the hydrogen <100ppm contained.

Title: Optical transmitting circuit
Inventor: MIKAMI KAZUO
IPC: H04B1/04
Filed: 1983-09-05
Abstract: PURPOSE:To extend a transmission length by connecting a constant current circuit in series to an optical transmission circuit consisting of a parallel circuit of a light emitting element and a switching element which controls the light emitting element and suppressing a variance of current of the optical transmitting circuit to increase the current of the light emitting element. CONSTITUTION:When the low level is inputted to an input terminal IN, a switching transistor TR24 is turned off, and a current Il of a constant current circuit 23 is flowed to a light emitting element 21 to allow the element 21 to emit light. When the input level goes to high, the TR24 is turned on, and a current IS of the constant current circuit 23 is flowed to the TR24, and the current Il is not flowed to the light emitting element 21. A certain current Id is flowed to a driving circuit 22 from a terminal TP. Consequently, a power source current I0 is equal to Il+Id or IS+Id and is approximately constant. Thus, the variance of current of the optical transmitting circuit is reduced to increase the current of the light emitting element, and the transmission length of light is extended to extend transmission/reception length.

Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To provide a message transmission system which can easily transmit an identical message to plural mobile terminals and can arbitrarily specify the mobile terminal of a multi-address object. SOLUTION: Common group identifiers are imparted to plural mobile terminals and correspondence relationships between these group identifiers and calling numbers of the plural mobile terminals belonging to the former are stored as member tables by each of mobile terminals 1a, 1b, 1c, 1d and 1e. Thus, when an arbitrary mobile terminal 1a, 1b, 1c, 1d or 1e receives a multi-address message accompanied by this group identifier, this member table is referred to on the basis of the group identifier, a multi-address message 101 is transmitted to a next transmission destination, and the mobile terminal 1a, 1b, 1c, 1d or 1e which receives the multi-address message 101 transmits the multi-address message 101 accompanyied by this group identifier one after another.

Title: Distortion detecting apparatus
Inventor: UTSUI YOSHIHIKO
IPC: G01L3/10
Filed: 1990-06-20
Abstract: PURPOSE:To detect abnormality of a detecting circuit by synchronously detecting outputs of two detecting coils with driving timings in a positive and a negative directions of an alternating current driving circuit, respectively, and then smoothing/amplifying the outputs thereby obtaining two distortion detecting outputs. CONSTITUTION:An output between two terminals of detecting coils 3a, 3b is input to differential amplifier circuits 5a, 5b, respectively. Outputs from the circuits 5a, 5b are input to synchronous detecting circuits 8a, 8b through capacitors 12a, 12b, where the outputs are synchronously detected by a first and a second synchronous detecting signals synchronized with the driving timing in a positive and a negative directions of an alternating current driving circuit 7. Inductances of the coils 3a, 3b are differentially processed in the detected outputs, and the thermal stress or bending stress when both of the inductances are changed in the same direction is cancelled. Therefore, when the detected outputs are smoothed and amplified at 9a, 9b to be generated as outputs Vout 1, Vout 2, these outputs are reverse in polarity to the impressed torque. If the circuits are turned defective or abnormal, one of the outputs becomes abnormal, thereby making it possible to detect the abnormality of the circuits.
