IPC: G01N27/414
Filed: 1989-08-31
Abstract: PURPOSE:To obtain the sensor which has high measurement accuracy and is usable without calibrating the output value corresponding to an ion concn. by forming the silver chloride particles of silver chloride layers essentially consisting of the silver chloride to <=1mum grain size. CONSTITUTION:Silver layers 2a, 2b are respectively formed by electroplating on copper electrodes 1a, 1b and the silver chloride layers 3a, 3b are formed on the surfaces of the silver layers 2a, 2b. The silver chloride particles of the silver layers 2a, 2b are formed to <=1mum grain size. The silver chloride layer 3a is coated with an ion sensitive film 4 essentially consisting of a vinyl chloride/vinyl acetate copolymer. A dam body 5 is formed of the insulator of an epoxy resin so as to enclose the electrode formed with this ion sensitive film 4 and the silver chloride layer 3b. The sensor plate which is laminated with the silver layers 2a, 2b and the silver chloride layers 3a, 3b respectively on the copper electrodes 1a, 1b, is provided with the ion sensitive film 4 on the silver chloride layer 3a and uses the silver chloride layer 3b as a reference electrode for sepn. is obtd. in such a manner. Since the silver chloride particles are densely packed at a high density, the fluctuation of the potential generated between the silver chloride layers and the ion sensitive film is lessened.

Filed: 1988-09-06
Abstract: PURPOSE:To facilitate insertion of a tube and to perform reliable sealing by a method wherein the inner part of a gasket hole disposed in a tube insertion hole formed in an end plate is connected to tank inner and outer side parts positioned to the inside and the outside of the end plate. CONSTITUTION:Gasket tank inner and outer side parts 11a and 11b are disposed to the tank inner and outer sides, respectively, of an end plate 6. A gasket hole inner part 11c is disposed in a tube insertion hole 9, and the gasket hole inner part 11c is connected to the gasket tank outer side part 11b to integrally form a gasket 11. Mounting of a tube 2 to the tube insertion hole 9 with the gasket 11 located therebetween is such that the tube is inserted into the tube insertion hole 9 of the end plate 6 from the outside of the tank. In this case, since the gasket hole inner part 11c is dragged but is held by the gasket tank outer part 11b, it is not drawn in. Thereafter, the tube is expanded from the inside of the tank by means of a punch, and the tube 2 is mounted to the end plate 6 through the medium of the gasket 11.

Title: Radio receiver
Inventor: TAURA KENICHI
IPC: H04H60/15
Filed: 1994-09-19
Abstract: PURPOSE: To automatically reproduce a specific announcement by attenuating a main sound signal to simultaneously reproduce main and auxiliary sounds by a controller in the case of auxiliary sounds of a prescribed type and reproducing only the main sound signal by the controller in the case of auxiliary sounds of the other type. CONSTITUTION: A controller 9 monitors the content discrimination code of the auxiliary sound signal. When the announcement of a prescribed type, for example, traffic information is broadcasted, the controller controls a variable attenuator 3 of a main sound signal route to properly attenuate the main sound signal. The controller closes a switch means 4 of an auxiliary sound signal route to allow the auxiliary sound signal to pass through.  When traffic information is not broadcasted, the controller controls the attenuator 3 to allow the main sound signal to pass through without attenuating and opens the switch means 4 of the auxiliary sound signal route to stop the auxiliary sound signal from passing through. since an adder 5 adds the outputs of a filter 3 and the switch means 4 and outputs the result to a sound reproducing part in the succeeding stage, traffic information of the auxiliary sound signal is loudly reproduced and the main sound signal program is reproduced with a properly low sound volume when traffic information is broadcasted.

Title: Method for forming recessed part on surface of tube material
Inventor: NAKAMURA MASANOBU
IPC: B21D26/041
Filed: 1990-08-24
Abstract: PURPOSE:To easily form the recessed part on tube material by bulging one part of the tube material, forming the bulging projection, pressing the pressing component to this bulged projection and projecting the above bulging projection inward the inside of the tube material. CONSTITUTION:A part of a tube material of the part to be formed to the recessed part is bulged and the bulging projection 15 is formed. The bulging projection is made to project inward to the inside of tube material by pressing the pressing component 17 having the die part corresponding to the recessed shape to be formed at this bulging projection. As the result, the bulging projection is sufficiently extended into the inside of tube material, the recessed part having a corner part formed with a small round can be formed. Therefore, because the corner part 2 of the recessed part 3 is not formed to the large round, and the idle space is not formed between the recessed part and the stopper 4, the clearance is not generated between the recessed part and the stopper. The recessed part of the tube material for stopping the tube material at the prescribed position with the stopper can be easily manufactured.
