Title: Thermistor temperature detecting circuit
Inventor: YAMAMOTO IZUMI
IPC: G01K7/24
Filed: 1993-07-09
Abstract: PURPOSE:To provide a protecting circuit, which suppresses the generation of progress of the migration of a thermistor, in a temperature detecting circuit, wherein a voltage dividing resistor is connected in series with the thermistor, a DC voltage is applied, and the change in voltage at a connecting point is outputted. CONSTITUTION:In a temperature control circuit, a connecting point 3 between a thermistor 1 and a voltage dividing resistor 2 is connected to an analog input terminal 6. Furthermore, a thermistor shorting circuit 8 using a transistor is connected to an output terminal 7 from the connecting point 3 in parallel with the thermistor 1. The voltage is applied on the thermistor 1 only when the output voltage at the output terminal 7 is at the 'Lo' level. The time is within one second including the reading time of an A/D converter and the delay time of the waveform. The temperature detection can be performed intermittently for a required time. The voltage application time on the thermistor 1 becomes very short in comparison with continuous application. For the generation of the migration of the thermistor, the temperature and the potential difference are required, and progress of the migration of thermister is suppressed by shortening the time, wherein there is no potential difference.

Title: Extra length treating case of optical fiber
Inventor: HAYASHI YUKIO
IPC: G02B6/44
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to avoid housing of connected extra lengths and separate coated fibers at the same point and to carry out the work for housing the extra lengths in the separated state of an extra length housing case and a separate coated fiber housing case by separating both cases. SOLUTION: The extra length treating case 4 for optical fibers 1 is formed separable to the extra length housing case 5 and the separate coated fiber case 6. The coupling of these cases is executed by inserting fixing pawls 21 formed in the lower part of the extra length housing case 5 into fixing holes 22 formed at the separated coated fiber housing case 6. The extra length housing case 5 for housing the connected extra lengths of the optical fibers 1 and the separated coated fiber housing case 6 are separated and, therefore, the parts of the single-core separate coated fibers 3 are kept free from undue stresses even at the time of carrying out the work described above with the extra length treating case 4. The possibility of damaging the separate coated fibers 3 is, therefore, lowered.  Then, there is no need for providing the parts of the separate coated fibers 3 with special protection, such as reinforcement with cords or coating and the cost thereof is reduced.

Title: Method for obtaining signal to contain spin spin releasing time information
Inventor: YAMASHITA MASAYA
IPC: A61B5/05
Filed: 1988-07-08
Abstract: PURPOSE:To suppress the deterioration of S/N of an echo signal being a second and subsequent one by prolonging a sampling time as the fetch of the echo signal is slow among plural echo signals, and simultaneously, releasing the inclination of a gradient magnetic field for reading. CONSTITUTION:A spin is excited by an exciting pulse, and thereafter, a 180 deg. pulse is periodically impressed. The sampling time is prolonged as the fetch of the echo signal is slow among plural echo signals, and simultaneously, the inclination of the gradient magnetic field for reading is released. For example, the sampling time of a second echo signal P2 is made into a length two-fold that of a first echo signal P1. Consequently the inclination of the gradient magnetic field for reading of the second echo signal P2 is released into the half of the first echo signal P1, the rephase speed of the spin is delayed into a half, and thereby, the generation time of the echo signal is prolonged to the double.
