Title: Stepping motor driving device
Inventor: CHIYOU HOUSEN
IPC: B62D1/18
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To avoid any damage to a stepping motor when the motor is overloaded by comparing the expected current value of the motor with the conducting current value detected by means of current detecting means by means of a motor drive instructing means when the voltage instructed by a voltage instructing signal is impressed upon the stepping motor or generating step-out information when the compared results do not fall with a set range. SOLUTION: The value of an expected current which flows to a stepping motor 171 when the voltage instructed by voltage instructing signals PA1 and PB1 from a motor drive instructing means is impressed upon a stepping motor 171 in response to the signals PA1 and PB1 is compared with the value of the conducting current of the motor 171 which is made to flow to the motor 171 when a motor driver 199a impresses a voltage upon the motor 171 in response to the signals PA1 and PB1 and detected by means of current detecting means 101AI, 101A2, 101BI, and 101B2. When the compared results do not fall within a set range, step-out information is generated. Therefore, any damage to the stepping motor can be avoided when the motor is overloaded.

Title: Hot water supply apparatus
Inventor: FUKUCHI TORU
IPC: F25B30/02
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To make a decision easily whether an abnormal state is present in a heat exchanger or not by providing a pair of conduction stopping means, respectively, on the upstream side and downstream side of a heat exchanger in a hot water conduction channel and making a decision whether a detected pressure is higher than a set level or not based on pressure detection information under a state where conduction of hot water is stopped. SOLUTION: A hot water supply controller TC controls a circulation pump 3, a combustor N, three-way valves 7b, 8b, 9b, and an on/off valve V based on a command from a hot water supply operating unit KS and performs hot water supply operation. If a minimum necessary hot water is not stored in a hot water storage tank at the execution timing of hot water supply operation, hot water storage operation is performed. Every time when a set time elapses, a pair of on/off valves are switched to conduction stop state and a decision is made whether a detected pressure is higher than a set level or not based on information detected through a pressure sensor P. If a detected pressure is higher than the set level, a decision is made that a heat exchanger is abnormal and hot water supply operation is stopped.

Filed: 1990-11-30
Abstract: PURPOSE:To enable blood vessel edges to be extracted at any time by using subtraction image data, producing blood vessel profiles, using prescribed values set according to photographing conditions and extracting blood vessel edges from the profiles. CONSTITUTION:An X-ray processing device 2 takes in image data from an image supplying device 1 and processes the data, and supplies the processed data to a TV monitor 3 for display on it. Namely, plotographing conditions are set to photograph objects of inspection, under which conditions a difference is gained between mask image data before injecting an angiography agent and live image data after injecting an angiography agent by a subtracter 30 for subtraction image data. By using this subtraction image data, blood vessel profiles are produced with a profile circuit 32, from which profiles blood vessel edges are extracted by using prescribed values set sccording to photographing conditions. This can always extract the blood vessel edges with accuracy.

Title: Waveform shaping circuit for recorded information reproducer
Inventor: IWANAGA TOSHIAKI
IPC: G11B20/10
Filed: 1991-12-25
Abstract: PURPOSE:To suppress the edge shift of a high density recording pit by slicing the differential signal and subtracting this signal from a read signal after differentiating the read signal and inverting the phase of the read signal. CONSTITUTION:The signal read out of a recording pit and detected by an optical head 1 is amplified by an amplifier 2 containing an LPF. The output of this amplification is differentiated by a differentiating circuit 3 and the phase of the read signal is inverted by 180 deg. by a phase inverting amplifier 4. Then a clip circuit 5 consisting of a Schottky diode shapes the waveform to equalize the positive peak amplitude of the differential signal to the negative peak amplitude. Then a differential amplifier 6 performs the subtraction between the clipped differential signals and the read signal to obtain a waveform-shaped signal. Thus the front and back edge tilts are properly corrected.
