Title: Ultrasonic probe
Inventor: HAYAKAWA YASUO
IPC: G01N29/24
Filed: 1988-08-06
Abstract: PURPOSE:To easily make the focus of an ultrasonic wave coincident with the surface of a sample by fixing a 1st and a 2nd visible light source to the ultrasonic probe and making the light from the 1st visible light source and the light from the 2nd visible light source cross each other at the focus. CONSTITUTION:The laser beams 20b and 21b from the laser oscillators 20 and 21 enters optical fibers 22 and 23 and are emitted toward the focus F. The laser beams 20b and 21b, therefore, cross each other at the focus F. When the surface of the sample is at a position (a), the spots of the laser beams 20b and 21b are at a distance from each other and when the sample surface is at a position close to the focus F, the opposite ends of both spots overlap with each other. Then when the sample surface is at a position (c) coincident with the focus F, both spots are put one over the other to become one spot. Thus, the laser beams 20b and 21b of the two laser oscillators 20 and 21 are passed through the optical fibers 22 and 23 to cross each other at the focus F, thereby easily focusing the beams on the sample surface.

Title: Instrument for measuring smoke density in exhaust gas
Inventor: YOKOTA HAYATO
IPC: G01N21/53
Filed: 1988-08-08
Abstract: PURPOSE:To exactly measure the smoke density in an exhaust gas by providing 1st and 2nd shielding pipes connected respectively to a light projecting device and light receiving device and projected in an exhaust gas passage and supplying purging air to the 1st and 2nd shielding pipes. CONSTITUTION:The 1st and 2nd shielding pipes 9a, 9b are connected respectively to the light projecting device 4 and the light receiving device 5. The shielding pipes 9a, 9b are projected in the exhaust gas passage. The high-temp. purging air is supplied via a purging air supplying pipe 8 to the shielding pipes 9a, 9b. Since the temp. in the central part of the passage 1 is higher than the temp. in the peripheral part in case of measuring the smoke density in the passage 1 with a soot concn. meter 6, the steam is not liquefied in the central part of the passage 1 even when the satd. steam is contained in the exhaust gas 2 and, therefore, the water drops of the steam are not irradiated with a light beam 3. the smoke density in the exhaust gas is thus exactly measured.

Title: Fuel assembly for fast breeder
Inventor: IWASAKI MAKOTO
IPC: G21C3/338
Filed: 1988-08-08
Abstract: PURPOSE:To decrease interaction (BDI) by forming a wire spacer to the diameter smaller near the central part of a reactor core than in the other parts and applying plating to this part so that the plating exfoliates and the wire diameter decreases when the BID arises. CONSTITUTION:The fuel assembly is constituted by winding the wire spacer 2 around the outer periphery of a fuel pin 1; for example, a region A has 525mm length, a region B 350mm and a region C 1,125mm in the axial direction. Although the diameter of the spacer 2 is 1.4mm in the regions A and C, the diameter is smaller in the region B. The plating is applied to the part of the spacer 2 where the diameter is reduced. Since the material of the spacer 2 is a stainless steel, nickel, etc., are adequate as the material for plating. The spacer 2 is formed to the diameter smaller in the central part of the reactor core where the BDI is liable to arise than in the other parts and the plating is applied to this part; therefore, the plating part exfoliates and the diameter of the spacer 2 decreases to decrease the BDI when the BDI is generated by the expansion of a fuel cladding pipe and the spacer 2.

Filed: 1989-07-28
Abstract: PURPOSE:To attain excellent image reception by a receiver for High Vision or the like by varying a phase of a vertical synchronizing signal to shift a displayed video image in the vertical direction and converting the vertical synchronizing signal into a pseudo vertical synchronizing signal for image reception. CONSTITUTION:A vertical synchronizing processing circuit 10 changes a phase by a quantity based on an adjustment data obtained from an external device and supplies an outputted pseudo vertical synchronizing signal VD to a deflection circuit 9.

Title: Optical sensor drive circuit
Inventor: SATO TSUGUO
IPC: H03F3/08
Filed: 1989-07-28
Abstract: PURPOSE:To prevent external noise from being mixed and to prevent of chattering the generation by providing a resistor to limit the driving current of a light emitting element, and an amplifier to amplify current to be generated by a light receiving element at the time of light reception, adding the output current of this amplifier to the limited driving current and making the added current flow to the light emitting element. CONSTITUTION:When a transistor 21 is switched from OFF to ON, the output current of a phototransistor 12 is small depending on light reception amount and corresponding to this output current, the collector current of the transistor 21 is comparatively small as well. However, since this collector current is added to an initial driving current by a resistor 22 and drives a diode 11, the light emission amount of the diode 11 is increased. With this increase, the collector current of the transistor 21 increased and a positive feedback loop is formed. By this positive feedback, since a main driving current speedily rises up after switching the transistor 21 to the ON state and reaches a maximum value depending in the resistance value of a resistor 16, chattering is prevented.
