Title: List lin7de for measuring characteristic of linear detector
Inventor: MIYAGAWA NOBUO
IPC: G01R31/00
Filed: 1997-04-26
Abstract: PROBLEM TO BE SOLVED: To accurately and quickly measure the characteristics of a linear detector by supplying the output of a signal generator to a linear detector and a modulation degree analyzer and the output of the linear detector to the external modulation input of the signal generator through an audio analyzer. SOLUTION: When the modulation degree characteristic of a linear detector 3 is measured with a modulation degree analyzer 2, the modulation level of a signal generator 1 is adjusted so that the deflection of the meter of the detector 3 can become the instructed value of a computer 5. After adjustment, the output of the generator 1 is supplied to the analyzer 2 and the analyzer 2 reads the output in accordance with a decoding signal sent from the computer 5. At the time of measuring the other characteristic of the detector 3, an audio analyzer 4 is operated by sending an operating signal from the computer 5 and the output of the analyzer 4 is supplied to the external modulation terminal of the generator 1. The output of the generator 1 is inputted to the detector 3 and the output of the detector 3 is measured by means of the analyzer 4.  Then the computer 5 reads the measured output of the analyzer 4 and a printer 6 prepares data.

Title: Hydraulic device of battery type industrial vehicle
Inventor: SUGIYAMA SHOJI
IPC: F15B21/14
Filed: 1989-06-19
Abstract: PURPOSE:To prevent erroneous selection of a returning line selector means by absorbing by a poor starting force absorbing means a poor starting force produced in a starting force transmitting path due to pulsation produced in a returning oil by abrupt lowering of a lift. CONSTITUTION:When a lift lever 6 is operated suddenly to lower a lift, the jumping of hydraulic oil in a lift cylinder 7 is generated due to shock and returning oil pressure may exceed a specified pilot pressure temporarily. A pressure of hydraulic oil in a lowering passage 5b for a control valve 5 is increased through a pipe 8 and pilot fluid is flown from a selector port 5a to a pilot line 12. The pilot fluid is controlled in flow rate and flow speed by a choke valve 13 and flown into the downstream of a control valve 11 in a bypass line D through a relief line R. Accordingly, the pilot pressure produced erroneously in the line 12 is absorbed in the relief line R and the selector valve 11 can not be switched over to (a) position. Thus, the low pressure returning oil will not flow into a pump 1 to eliminate any needless rotation.

Filed: 1989-06-21
Abstract: PURPOSE:To inspect the hardening degree of radioactive waste quickly and to make it possible to perform the total inspection by measuring the rotating speed from the initial rotation to the release of a brake. CONSTITUTION:The number of rotation of a synchronous motor 3 is transmitted to a flywheel 6 by way of a speed reducer 4 and a first electromagnetic clutch 5. When the flywheel 6 achieves the specified number of rotation, the first electromagnetic clutch 5 is released. Then, a second electromagnetic clutch 7 is connected, and the rotating energy of the flywheel 6 is transmitted to a drum can 1 through a bevel gear 8 and a turntable 2. The number of rotation of the drum can 1 is detected by a number-of- rotation detector 9. The number of rotation per unit time of the drum can 1 can be detected by a number-of- rotation measuring device 10. Namely, the rotational speed of the container from the initial rotation to the release of a brake is measured, and the hardening degree of radioactive waste is judged based on the presence or absence of the inertia of motion when the radioactive waste is fluid. Since the judgment can be performed without destruction, the total inspection of the container can be performed.

Title: Dsb transmitter
Inventor: NAKAMURA KOREKIMI
IPC: H04B1/04
Filed: 1988-06-24
Abstract: PURPOSE:To avoid the extension of an occupied frequency band of the transmitter even in the overmodulation and to preclude the possibility of causing cross talk fault by providing a narrow band filter passing only a carrier signal with a prescriber band width to the post-stage of a modulator. CONSTITUTION:An amplitude (AM) modulator 9 and a narrow band pass filter 10 are provided between an oscillation circuit 2 and a mixer 8 and the amplitude modulator 9 applies modulation to a carrier from the oscillation circuit 2. Thus, even without the provision of a low frequency power amplifier, the modulation is applied by a signal level from a low frequency amplifier. Since the narrow band pass filter 10 is provided on the post stage of the amplitude modulator 9 in this way, even if overmodulation take place or the frequency band of the low frequency amplifier 6 is spread, the occupied frequency band of the transmitter depends on the filter characteristic of the narrow band filter 10. Thus, the occupied frequency band is not spread and cross talk is prevented.
