Title: Controlling device for hot-water supplying apparatus
Inventor: IKENAGA MITSUO
IPC: F24H1/10
Filed: 1991-10-28
Abstract: PURPOSE:To make the execution of fluctuation control more satisfactory by a method wherein, when an instruction ordering the execution of fluctuation control is given while feedwater taken in is being monitored and being heated by a heating means, the fluctuation control is executed provided that the temperature of the water taken in is below a specific point which is conditional on a prescribed reference temperature. CONSTITUTION:A tuning on of a fluctuation control switch, giving an instruction to execute fluctuation control, while feedwater taken in is being monitored by a feedwater flow rate sensor 31 and hot-water heating is in operation with a main burner 2 lighted, causes a controlling device to check on the temperature of the feedwater. To be more specific, the temperature of the feedwater detected by a feedwater temperature thermistor 32 is read and compared with the conditional temperature which differs by a certain degree from a reference temperature set by a hot-water temperature-setting switch. When the temperature of the feedwater is lower than the conditional temperature, the fluctuation control is executed and the feedwater temperature is varied within a specified range of temperature. When, contrarily, the feedwater temperature is above the conditional temperature, the fluctuation control is not executed. This method prevents inadequate fluctuation, that is, a failure in obtaining changes of temperature in regular patterns which is due to high temperatures of inflowing water.

Filed: 1986-11-28
Abstract: PURPOSE:To obtain a high modulation reproduction signal without wave distortion by specifying the arrangement of a semiconductor laser and an information recording medium. CONSTITUTION:A laser flux 2 out of the semiconductor laser 1 is stopped on an information track 7 on the information recording medium 6 through a lens 3, a mirror deflecting device 4 and a stopping lens 5. At that time the joint surface of the laser 1 points a direction (x), and the laser 1 is arranged so that said direction (x) can be perpendicular to the direction y' of the track 7. In terms of a laser spot stopped on the track due to said arrangement, its oblong directions intersect orthogonally, whereby the laser spot evades from simultaneously lighting information pits on the track. Thus the high modulation reproduction video signal can be obtained with less waveform distortion.

IPC: G01R31/12
Filed: 1986-11-28
Abstract: PURPOSE:To detect insulation deterioration of a power cable with a high sensitivity, by employing a clamp type voltage injector and a clamp type current measuring device. CONSTITUTION:A clamp type voltage injector 25 is mounted to a mid-point ground wire 15 of a ground transformer 14 and a coil thereof 25 is connected to a low frequency power source 26. When a voltage with a frequency lower than commercial frequency is applied from the power source 26, a low frequency voltage is induced in a closed circuit containing the ground wire 15. On the other hand, a clamp type current detector 27 is mounted to shielding body ground wire 16 of the power cable 13 to detect a leakage current. Current detected is passed through a low frequency filter 28 to extract current based on an applied voltage of the device 25 therefrom and the results are inputted into a waveform analyzer 29. Thus, the analyzer 29 analyzes a voltage waveform from the power source 26 and a current waveform extracted from the leakage current thereby enabling the diagnosing of insulation deterioration of the power cable 13 with a high sensitivity.

Title: Objective distance measuring device
Inventor: BABA SATOSHI
IPC: G01S7/48
Filed: 1993-11-11
Abstract: PURPOSE:To perform an abnormality diagnosis every distance measurement by comparing the count value at the point of time when a pseudo distance measurement signal in which diagnosis signal is delayed for a fixed time is received with the delay time. CONSTITUTION:Timer counting is started simultaneously with the transmission of a distance measurement signal 24, and at the point of time when the distance measurement signal reflected by an object 28 is received, 1/2 of the timer count value is multiplied by the advancing speed of the measurement signal to measure the objective distance. A counter circuit 22 restarts counting by a diagnosis signal 32 every completion of distance measurement, a delay circuit 33 delays a diagnosis pulse by a prescribed time Td. A LED driving circuit 34 inputs the diagnosis signal outputted after delay as a pseudo distance measurement signal to drive a LED 35. The circuit 22 inputs a counting stop signal which received 30 this emission, and stops the counting at the point of time when the time Td passes from the counting restart point. A CPU 23 inversely operates a pseudo reciprocating time T from the distance measurement value by the pseudo distance measurement signal, compares times T, Td to each other, judges no abnormality when T-T0 is less than an allowable error, and gives an abnormality alarm when it is the allowable error or more.

Title: Optical pickup
Inventor: FUJIKAWA KAZUHIRO
IPC: G11B7/125
Filed: 1989-11-01
Abstract: PURPOSE:To correct the astigmatism of the light spot of an optical pickup in all directions by connecting a light source holding member to a connection member in such a way that it can slant and be assembled to an optical axis in an arbitrary direction via an adjusting fixing means. CONSTITUTION:The light source holding member 13 is connected to the connection member 18 in such a way that it can slant and be assembled in the arbitrary direction to the optical axis via the adjusting fixing means. In other words, the light source holding member 13 is connected to a pickup main body 19 via the connection member 18, and the light source holding member 13 is fixed by adjusting a tilt angle against the connection member 18 setting a pivot 22 as a fulcrum P by rotating screws 20, 21 for tilt adjustment as keeping balance with a screw 27 for fixing having a spring 28. Therefore, when the astigmatism occurs in the light spot 9 on the recording plane of an information recording medium 8, the correction is performed by rotating the screws 20, 21 for tilt adjustment corresponding to that direction and inclining the light source holding member 13 against the connection member 18. Thereby, it is possible to correct the astigmatism in all directions generated by the incidence of an optical beam to a beam arranging prism 3.
