Abstract: PURPOSE:To enable taking out the laser output subjected to efficient optical modulation with a small optical loss by providing a modulating means which changes the bending loss or the optical path length of an optical fiber. CONSTITUTION:A GaAs laser 11 is driven to emit light, and the exciting light condensed by a rod lens 12 is made incident on an optical fiber 10, and adjustment is performed to obtain a maximum quantity of incident light. The optical fiber laser is set to the continuous wave oscillating state by this adjustment. A standard signal generator SSG 19 is driven and a pulse signal is applied to a piezo-oscillator 18 through a cable 20. At this time, the length, namely, the optical path length of an optical fiber 10 wound around the oscillator 18 is periodically changed in accordance with expansion and contraction of the piezo-oscillator 18, and the laser light is subjected to phase modulation at the same period as the frequency of the pulse signal given to the piezo-oscillator. Thus, the laser output subjected to required optical modulation is obtained.

Title: Planographic printing method
Inventor: KONDO TOSHIRO
IPC: B41F27/14
Filed: 1987-01-12
Abstract: PURPOSE:To mount a plurality of planographic plates and enable printing of a book or magazine form printed matter having a multiplicity of leaves, by a construction wherein dampening water can not penetrate between the leading end of each of the second and latter planographic plates mounted on a flexible support base and the support base, and an ink is not received by this structure part. CONSTITUTION:Planographic plates P1 and P4 and planographic plates P2 and P3 are so arranged that the upper parts of respective manuscripts are opposed to each other, and the face side of a thin film 2 being adhesive on the back side is made to be highly hydrophilic so that the face side does not receive a printing ink during printing. The printing plates P1-P4 are mounted on a plate cylinder by gripping the leading ends of the first plates P1 and P2 by the cylinder, and then gripping the trailing ends of the second printing plates P2 and P3 by the cylinder. Printing is started by rotating the cylinder in the direction of an arrow. Dampening water flows in the same direction as the arrow, but it can not penetrate between the leading end of the second plates P2 and P3 and a flexible support base 1, due to the presence of the film. In addition, the surface of the film 2 is highly hydrophilic. Therefore, an ink is not adhered to this structure part except that two unrequired lines are printed due to adhesion of small amounts of the ink to a trailing edge part of the plates P1 and P4 and an edge part of the film 2.

CONSTITUTION:A water temperature T1 of a water supply pipe 6 is obtained by a temperature sensor S1, and hot water temperatures T2 and T3 at the inlet side and outlet side of a hot water supply pipe 7 are obtained by temperature sensors S2 and S3, and a hot water temperature T4 of a discharge hot water pipe 10 is obtained by a temperature sensor S4, and the temperature information and discharge hot water flow rate information for a requested hot water temperature are obtained by a remote control device 13 respectively. Then, the detected hot water temperatures T2 and T3 at the temperature sensors S2 and S3 are compared, and it is judged that both temperatures approximately agree or not. If they approximately agree, the discharge hot water temperature and control hot water temperature are operated, and a driving motor 9 for an electrically operated mixing valve 8 is rotation-controlled. By this method, influence on a user can be reduced as low as possible.

Title: Checking of continuity for substrate having circuit
Inventor: KITADA MASUZO
IPC: G01R31/02
Filed: 1988-01-14
Abstract: PURPOSE:To achieve higher inspection efficiency by a method wherein a DC signal for inspecting short-circuiting is mixed with an AC signal for inspecting disconnection to be fed to a circuit and a contact with a terminal of a superhigh density circuit is accomplished through a conducting rubber to check the presence of a disconnection with a liquid crystal bar. CONSTITUTION:Contact pins 2 are kept in contact with a terminal on the side of an IC or an LSI of a circuit board 1 to be inspected while a conducting rubber sheet 7 is pressed on a pattern for high density, for example, on a liquid crystal side terminal. Then, a mixture of DC for detecting short-circuiting and AC for detecting disconnection is sent as electrical signal. In the electrical signal, the DC signal detects the state of continuity between the pins 2 to be compared with a reference data or a design data and when there is discrepancy therebetween, as error, the position of a land where a short circuiting occurs, a pin No. or a circuit No. is displayed or printed out. On the other hand, an AC signal conducted to lands of the circuit board 1 through the pins 2 and the sheet 7 detects the state of energization between the pins 2 and the presence and the location of a disconnection is shown on a liquid crystal display plate 3. Thus, it will suffice to directly inspect the display passing through a transparent depression plate 6.

Title: Fault diagnostic system
Inventor: TAGUCHI AKIYOSHI
IPC: H04Q3/545
Filed: 1992-01-16
Abstract: PURPOSE:To make an efficient fault diagnosis by restarting a diagnostic program from the interrupted state. CONSTITUTION:A diagnostic result storage means 1 stores the result of diagnosis at the time of interrupting a diagnostic program. In the means 1, for example, information indicating whether or not a diagnostic program is interrupted and the result of the diagnosis up to the interruption are stored. A discrimination means 2 discriminates whether or not the interrupted diagnostic program is existent at the time of executing the diagnostic program. A restarting means 3 restarts the diagnostic program from the interrupted state based on the diagnostic result at the time of interruption when the diagnostic program interrupted by the means 2 is judged to be existed. Thus, the waste processing time due to the execution of the diagnostic program once more from the start can be eliminated, making an efficient fault diagnosis.
