Title: Exhaust method for cathode-ray tube
Inventor: TOYAMA NOBORU
IPC: H01J9/385
Filed: 1980-11-12
Abstract: PURPOSE:To prevent sintering of oxide during exhaust activation by dividing the exhaust activation into the following steps, decomposition of carbonate and activation of a cathode. CONSTITUTION:First for the cathode surface, carbonate is decomposed by increasing the temperature of the cathode by steps, for instance, within the range of 500-950 deg.C. In this case, the pressure within a bulb tube is increased temporarily by the emission of cracked gas. Then the intra-tube pressure is decreased by stopping the ignition of a heater and discharging the cracked gas. In this case, for example, the temperature of the cathode surface is reduced below 700 deg.C and the sintering caused by the high temperature heating of the cathode under the low vacuum is prevented. Next, the heater is ignited again after the intra- tube pressure is decreased, and the temperature of cathode is maintained within the range of 800-950 deg.C, so as to restart activation. As described the above, by dividing activation, the degree of vacuum can be improved during the interruption time and the sintering of oxide during the exhaust activation can be certainly prevented.

Title: Co2 laser device
Inventor: TERADA SETSUO
IPC: B23K26/00
Filed: 1988-06-27
Abstract: PURPOSE:To assure a satisfactory laser output by enlarging the inner diameter of a discharge tube by reducing gas flow passage resistance between the discharge tube and a circulation passage by making an effective diameter of at least one of a partial transmission mirror and a final stage mirror located at a final end position opposite to said mirror equal to an effective diameter required for bringing a laser beam into a single mode, and making larger the diameter of the discharge tube than said effective diameter. CONSTITUTION:A CO2 gas laser medium is circulated at a high speed in a discharge tube 2 and a circulation passage 3 by means of a tool blower, and excited in the discharge tube 2. Hereby, a laser beam is emitted and taken out to the outside through a half mirror 9. Thereupon, effective diameters of the half mirror 9 and a final stage mirror 8 are made equal to an effective diameter required for bringing the laser beam into a single mode. Accordingly, a more stable single mode can be obtained and the diameter of the discharge tube 2 is nade variable. With such construction, an inner diameter of the discharge tube 2 is made substantially equal to that of the circulation passage 3. Hereby, flow resistance which might be produced at a mode between the discharge tube 2 and the circulation passage 3, can be reduced, and permits a difference between pressure P1 in the circulation passage 3 at an inlet side of the laser medium and pressure P2 at the outlet side is substantially zero. Thus, flow capability of the tool blower is developed to the utmost to assure sufficient laser output.

Title: Double pipe type head loading type pile perpendicular load test method
Inventor: HIBINO SHINICHI
IPC: E02D1/02
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To reliably transmit a load weight at a pile head to a pile top end and enable an accurate perpendicular load test by a method wherein an inner pipe is freely and slidably engaged with an outer pipe, and by use of a fiictional resistance on an outer periphery of the outer pipe as a reaction force, a perpendicular supporting load at a top end part of the inner pipe is measured. SOLUTION: An inner pipe 2 is freely, slidably and axially engaged with an outer pipe 1 and a test pile is penetrated into a ground 6. A top end of the test pile enlarges the inner pipe 2 in a diameter so as to be equalized to the outer pipe 1 by a pipe enlarging connection, and projects it downwardly of the outer pipe 1, so that a perpendicular load weight is transmitted to the support ground 6 and its reaction force is taken for the outer pipe 1. An apex part of the inner pipe 2 is coupled to a seat 5 and an apex part of the outer pipe 1 is coupled to load beams 3 between which a jack 4 is provided. Further, a space between the inner pipes 2 is held at a constant interval by a spacer 8'.  Accordingly, when a load weight is applied by the jack 4 at the time of load test, by use of a circumferential face frictional resistance of the outer pipe 1 via the load beam 3 as a reaction force, the inner pipe 2 is apt to be penetrated into the ground 6. At this time, a reaction force of load weight is transmitted to the outer pipe 1 and a frictional resistance works on an outer periphery of the outer pipe 1 in the ground 6, so that a support load of the pile is decided as the sum of the frictional resistance and the top end resistance.

Title: Oil feed apparatus
Inventor: HIRATA YOZO
IPC: B67D7/32
Filed: 1989-06-21
Abstract: PURPOSE:To assure the prevention of an oil vapor detection means from coming in contact with oil by providing an oil vapor detection means in an oil feed device separately from an oil feed nozzle and by detecting the concentration of the oil vapor sucked through a vapor suction pipe into a fuel tank. CONSTITUTION:When an insertion detection signal is entered into an air suction pump control circuit 24 from an insertion sensor 18 with a nozzle closing signal supplied from a nozzle switch 11, an air suction pump 16 rotates forwardly for a predetermined time. As a result, the oil vapor remaining in a fuel tank is discharged from a vapor suction opening 12a of an air suction hose 12 through an oil vapor detection sensor 15 into a weigher 1. If light oil remains in the tank, the resistance value of the resistor 15a of a sensor 15 remains almost unchanged due to a small amount of the oil vapor. For this reason, the output voltage from the sensor 15 does not reach a predetermined range and a comparative circuit 21 judges the oil in the tank as light oil to keep an action inhibiting signal energized. As a result, a pump motor control circuit 23 stops the driving of a pump motor 3 and an alarm 25 comes in operation to give a warning for a difference in oil kind.

Title: Photometric optical system of single-lens reflex camera
Inventor: FUJIBAYASHI KAZUO
IPC: G03B19/12
Filed: 1984-07-31
Abstract: PURPOSE:To attain precise photometry of external light by providing a small mirror with characteristics for the reflection of visual light and removal of infrared rays. CONSTITUTION:At the photometry of external light, a quick return mirror 2 is set up on a 45 deg. position as shown in the drawing. External light transmitted through a photographing lens 1 is transmitted through a half mirror part on the center part of the quick return mirror 2 and is made incident upon the small mirror 3. Since the small mirror 3 has characteristics for reflecting visual light and removing infrared rays, only the visual light is led into the bottom of the camera by the small mirror 3 and the infrared rays are absorbed by a light absorbing member 3a adhered to the back of the small mirror 3. The visual light reflected by the small mirror 3 is received by a photodetecting element 7 through a photometric lens 6. At the photometry of external light, only necessary visual light is detected by the photodetecting element 7 and precise photometry matched with film sensitivity can be attained.
