Abstract: PURPOSE:To obtain an optical fiber of low loss, by determining wire drawing tension according to a difference in specific refractive index of a preform and specifying residual stress of a core of the optical fiber after wire drawing at a given value or below in wire drawing of a preform for quartz based optical fiber containing a core having a higher softening point than that of a clad. CONSTITUTION:A preform for a quartz based optical fiber having a relation of T1>T2 between the softening point (T1) of a core glass and the softening point (T2) of a clad glass is produced. The resultant preform is then heated in a high-temperature furnace and wire drawing is carried out to produce the aimed optical fiber. The tension in wire drawing is simultaneously adjusted according to the difference in specific refractive index of the preform and the residual stress of the core of the optical fiber after wire drawing is specified at a given value or below. Thereby the difference in specific refractive index in the preform stage and designed cutoff wavelength can be sustained even after the fiber formation. As a result, the aimed optical fiber of low loss can be obtained.

Title: Focus magnet device for cathode ray tube
Inventor: FUJIMURA TAKEO
IPC: H01J29/68
Filed: 1980-02-12
Abstract: PURPOSE:To stabilize the flux to be contributed for the focusing, by providing a movable shunt section in a portion of leakage flux path while constituting the device such that the leakage flux passing through said movable shunt section will decrease in accordance with the temperature rise. CONSTITUTION:As the temperature rises the force of a permanent magnet 1 is weakened to reduce the flux to be produced. At the same time the extended section 213 of a magnetic path member 200 will bend toward outside due to the temperature characteristic of a bimetal because it isn't fixed to a cover 20. Consequently the magnetic resistance in a magnetic path for leakage flux 5 passing through the extended section 213 is increased to reduce the leakage flux 5 thus to compensate the reduction of flux produced in a cavity 2 due to the temperature rise.

Title: Differential pressure detector, method for judging abnormality in differential detector, and fuel evaporation gas delivery prevention device using differential detector
Inventor: KOSHIMIZU AKIRA
IPC: G01L19/06
Filed: 1994-02-10
Abstract: PURPOSE:To obtain a differential pressure detector which can judge the abnormality within a detector by providincj a pressure buffer member between a reference pressure introduction port and a reference pressure chamber for relaxing the I/O of a reference fluid and reducing the amount of I/O of reference fluid as compared with the amount of leakage between a reference pressure chamber and a pressure introduction port to be measured. CONSTITUTION:A pressure buffer member 17 consisting of a porous film 17a is provided between a reference pressure introduction port 11a and a reference pressure chamber 12 to relax I/O of atmospheric pressure. A differential pressure detector 10 introduces atmospheric pressure from the introduction port 11a and a pressure to be measured from a port 11b for introducing pressure to be measured, detects the differential pressure between the atmospheric pressure retained at the reference pressure chamber 12 and a pressure to be measured using a differential pressure detection element 13, and then calculates the pressure to be measured using an external CPU and then displays it. In this case, when the sealing between a reference pressure and a pressure to be measured is improper and a positive pressure (a pressure to be measured > a reference pressure) is applied, a fluid to be measured flowing to the reference chamber 12 is prevented by the film 17a, thus preventing a differential pressure from being generated. Also, when a negative pressure is applied, the flow-in of the atmospheric pressure can be prevented and no differential pressure is generated. Therefore, if an output value which is equivalent to that when there is no differential pressure, a detector is judged to be faulty.

Then, lead terminals 11 to 1n are scanned by an electron-beam tester EB, and individual potential levels of the lead terminals 11 to 1n corresponding to the first potential are measured. In the same manner, potential levels of individual lead terminals corresponding to a second potential are measured, and both measured levels are compared with a criterion level which is output so as to correspond to both potentials. A compared result is recorded in a computer for the tester EB, and whether bonded parts are disconnected or short-circuited can be discriminated at the individual lead terminals.

Title: Production of ceramic substrate
Inventor: KIMURA HITOSHI
IPC: C04B35/64
Filed: 1990-01-26
Abstract: PURPOSE:To obtain a ceramic substrate reduced in warp by introducing high- temperature retaining time in cooling process after burning a green sheet for ceramic substrate. CONSTITUTION:In a method for burning and then cooling a green sheet for ceramic substrate to produce the objective ceramic substrate, a process for keeping the sheet at a temperature higher than 1100 deg.C once during cooling is provided. The temperature in high-temperature retention requires a temperature higher than 1100 deg.C and is preferably lower than the burning temperature and temperature higher than the burning temperature is undesirable. When the sheet is retained in a temperature lower than 1100 deg.C, reduction of warp is not practiced. The warp in the resultant ceramic substrate is reduced and e.g. can be suppressed to a warp value no higher than 0.15 in 100mmX100mm dimension which is the standarized limit value of ceramic substrate. Consequently, any correction of warp becomes unnecessary.
