Title: Failure judging method for elevator position detector
Inventor: KIN TOMONORI
IPC: B66B5/00
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To make judgement about the failure of an elevator car position detector by making judgement about the abnormal state of the detector whenever the travel of the detector occurs across the plate of each layer. SOLUTION: An off-time(FT) is taken as a minimum time for an elevator car(EL) to escape an arbitrary layer, and an on-time(NT) taken as a time for the EL to pass the arbitrary layer. In addition, timing for the FT is initially set at 28 periods. When the EL does not escape a position detector(SE) at a step 5, one period is subtracted from the FT to generate 27 periods at a step 10. As the NT is not equal to zero, the FT is shortened, until the escape of the EL from a departure layer plate and when the FT is equal to zero at a step 11, an alarm is generated at a step 19. Also, when the SE enters the second plate and the maximum value of a plate travel time between the departure layer and an arrival layer is seven, an alarm is generated at a step 19, provided that the value of the NT is found larger than seven at a step 6.  When the SE passes the second plate and the value of the NT is equal to 1 at a step 16, an alarm is generated. In this way, the existence of the abnormal state of the SE is judged at every passage thereof across the plate of each layer.

Title: Liquid jet recording head
Inventor: NAGATOMO AKIRA
IPC: B41J2/14
Filed: 1985-12-27
Abstract: PURPOSE:To improve the service durability of a liquid jet recording head by using a material having a specific temperature coefficient as a heating resistance layer which constitutes an electricity/heat exchanger. CONSTITUTION:A liquid jet recording head 1 consists of an orifice 5 and a liquid flow channel 6 which are formed by using a grooved board 4 with a prearranged number of grooves of prearranged width and depth arranged at a prearranged linear density to cover the surface of a substrate 3 where an electricity/heat exchanger is provided. A heating resistance layer 11 is a thin layer of a material having a temperature coefficient of 15 to 60%/ deg.C. Setting the lower limits to 15%/ deg.C produces an effect from this value. In the meantime, setting the upper limits to 60%/ deg.C causes the resistance value of the heating resistance layer to be influenced by a room temperature, provided said upper limits are exceeded. Even when the temperatures of the heating resistance layer have soared by the application time of voltages to the heating resistance layer becoming longer than a rated energization time, the layer does not reach a high temperature level because it has a high positive temperature coefficient.

Title: Method for stabilizing laser beam for optical disk device
Inventor: EMA HIDETOSHI
IPC: G11B7/125
Filed: 1988-11-25
Abstract: PURPOSE:To extract and detect the component of a detected voltage corresponding to the light intensity of a succeeding low-level beam for confirmation and reproduction by passing the detected voltage proportional to a photovoltaic current detected by a photodetector through an upper-limit circuit. CONSTITUTION:A preceding beam A for recording and succeeding beam B for confirmation and reproduction are received by one photodetector 14. The photovoltaic current detected by the photodetector 14 becomes the sum of those of the two beams, but, since each beam contains erroneous fluctuating components, the component of each beam cannot be separated from each other in an uncomplicated way. When the voltage detected by the photodetector 14 is passed through an upper-limit circuit 18, the signal obtained from the circuit 18 becomes signals of a waveform containing no fluctuating component of the beam A for recording. When such signals are electrically processed, only the component corresponding to the light intensity of the succeeding beam for confirmation and reproduction having a low light intensity can be extracted and detected. Therefore, by controlling the light intensity of the succeeding beam B based on the detected result of the component, confirming and reproducing operations are performed under a fixed output.
