Title: Method for decreasing influence of eddy current by magnetic field gradient
Inventor: INOUE YUJI
IPC: G01R33/20
Filed: 1988-09-22
Abstract: PURPOSE:To decrease the influence of an eddy current due to magnetic field gradient by alternatively impressing a code positively and negatively at every sequence impression of a pulse sequence for a dephase gradient and a lead gradient to be a gradient magnetic field in a frequency direction. CONSTITUTION:In a first view, a dephase gradient 2 is impressed in a positive side after a stimulating pulse 1. A magnetic moment is aligned again by a reversing pulse 3 and an SE signal 4 is generated by a lead gradient 5. Then, a tomographic image is photographed. In a second view, a dephase gradient 5' of a negative pulse is added after the stimulating pulse 1 and a lead gradient 5' of the negative pulse is added after the reversing pulse 3. Then, the SE signal 4 is obtained. Since the position gradient 5 and negative gradient 5' are alternatively impressed as the gradient at every view for the pulse sequence, a remaining gradient 6, which is generated by the positive lead gradient 5 and left without being compensated, is canceled and becomes small since the direction of the gradient 6 is different from that of a remaining gradient 6' which is generated by the negative lead gradient 5'. Especially, even when the time constant of the eddy current is long and a residual gradient is accumulated at every view, the gradient is not left since the residual gradient is canceled in each time.

Title: Determining device for reduced quantity of hydraulic pressure at final gear shifting stage of automatic transmission
Inventor: KASHIWABARA YUJI
IPC: F16H59/24
Filed: 1988-09-22
Abstract: PURPOSE:To prevent the torque of an output shaft from being abruptly changed by determining the quantity of hydraulic pressure to be reduced in such a way that a friction engagement device is constant in torque capacity based on the detected relative revolutions and estimated change characteristics. CONSTITUTION:The relative revolutions of the input and output member of a friction engagement device and the bearing pressure of the input and output member are detected so that change characteristics of the frictional coefficient of the input and output members against the relative revolutions are estimated based on the bearing pressure. The reduced quantity of hydraulic pressure to be supplied is determined based on the detected relative revolutions and the estimated change characteristics of the frictional coefficient. In this case, the quantity to be reduced is determined in such a way that the friction engagement device is constant in torque capacity. As a result, at the final gear shifting stage, the frictional coefficient of the friction engagement device is transformed from the dynamic frictional one into the static frictional one with great influence; nevertheless hydraulic pressure to be supplied is reduced correspondingly to the change. The pressure is reduced in such a way that the friction engagement device is constant in torque capacity, an increase in shock due to gear shifting can thereby be prevented.

Title: Current monitor system
Inventor: TOYODA IKUO
IPC: H04M3/22
Filed: 1988-09-26
Abstract: PURPOSE:To allow the master set side to monitor the operating state of a slave set by adopting the constitution such that the master set monitors a current flowing to a line even when the slave set receives external power supply. CONSTITUTION:With a circuit of a changeover device 10 of a slave set 2 thrown to the position of contact (b), if power required for the slave set 2 is obtained from an external power supply connecting to a external power terminal 11, a detector 8 identifies the power supply state from the external power supply and closes the contact of the line switching section 9 when the state is normal. Thus, a dummy load 7 is connected to a line 3 and a current flows to a closing circuit from the power supply 4 of the master set 1 including the load 7. If power is not normally supplied from the external power supply, since the detection section 8 opens the contact of the switch section 9, the current on the line 3 is disappeared. the monitor section 5 detects the state above, then the master set 1 recognizes the state of the slave set 2.

Title: Solid-state image pickup device
Inventor: SHINJI UYA
IPC: H01L27/148
Filed: 1993-09-01
Abstract: PURPOSE: To reduce smear by a method wherein a well, which is shallower than the well formed on the lower part of a photodiode region, is formed on the lower part of a CCD channel region, and a conductive embedded well, which is made of the material same as a substrate, is formed on the lower part of the CCD channel region. CONSTITUTION: The first well layer 2, surrounding a photodiode 6, and the second well layer 3, surrounding a CCD channel region 4 and having the depth considerably shallower than the first well layer 2, are formed on the surface of an n-type Si substrate 1. As the first well layer 2 is not formed on the lower part of the CCD channel region 4, the second well layer 3 is formed in such a manner that it becomes the isolation region between the n-type Si substrate 1 and the CCD channel region 4. As the positive potential is biased by the n-type Si substrate 1 due to the discharge of excessive charge, the second well layer 3 is formed in sufficiently high density. As a result, an obliquely incident light is projected into the n-type substrate 1, and the generation of smear can be reduced.

Title: Transfer material separating device for image forming device
Inventor: SHIBAYAMA AKIHIRO
IPC: G03G15/14
Filed: 1989-09-18
Abstract: PURPOSE:To maintain the stable separate destaticizing function of a destaticizing device equipped with a saw tooth electrode for a long time by providing insulating abutting members on both sides of a destaticizing electrode and bringing their upper parts into press-contact with the surface of a photosensitive body. CONSTITUTION:The edge of the destaticizing electrode 5 facing the photosensitive body 1 is formed with plural saw tooth pats 5a. The insulating abutting members 8 are provided on both ends of the electrode, which are out of the transfer area of the photosensitive body 1. Since the upper part 8a of each abutting member 8 is in press-contact with the surface of the photosensitive body 1, the distance between the end part 5a and the surface of the photosensitive body 1 is kept constant. As the destaticizing electrode 5 is used, its discharge current weakens. However, the upper end 8a of the abutting member 8 is gradually worn by the rubbing of the photosensitive body 1 to shorten the distance up to the end part 5a. This shortening compensates the weakening of the discharge current. Consequently, troubles in separation and images can be efficiently prevented.
