Title: Processing method for photosensitive material for photographing
Inventor: NAKAMURA TAKASHI
IPC: G03D3/13
Filed: 1990-09-14
Abstract: PURPOSE:To prevent the generation of unequal processing and tailing of a photosensitive material by confining the forming density of perforations to within 4 pieces per image plane and injecting a processing liquid. CONSTITUTION:This photosensitive material F for photographing is formed with the perforations at the forming density within 4 pieces per image plane at one or both ends. Then, the forming density of the perforations is smaller and the flow of the processing liquid in the perforations decreases at the time of the passage in a narrow-path processing path 60A. The stirring effect by the injection of the processing liquid from injection nozzles 18 is consequently improved. The generation of the unequal processing is decreased in this way and the forming density of the perforations is small even when a blade 15 capable of shielding this processing path is installed and, therefore, the increase in the resistance for transporting the photosensitive material for photographing is prevented.

Title: Search control method of disk player
Inventor: KIRIYAMA YUKIMUNE
IPC: G11B19/02
Filed: 1994-10-07
Abstract: PURPOSE: To reduce the burden of the adjustable speed operation of a disk rotary motor by moving a pickup to a point, where the rotational speed of the motor is decreased, and changing linear velocity when search operation, in which linear velocity must be altered, is conducted. CONSTITUTION: When linear velocity is varied and search operation is performed, the linear velocity of a disk D is changed by a motor control circuit 11 when a system control circuit 9 decides the positioning of a target place on the inner circumferential side of the disk from a current place, and a pickup 3 is moved up to the target place by a pickup-feed control circuit 10. When the target place is positioned on the outer circumferential side from the current place, the pickup 3 is shifted up to the target place, and the linear velocity of the disk D is altered. Accordingly, the degree of the adjustable speed operation of a motor is diminished by varying the linear velocity of the disk at a point, where the difference of the rotational speed of the motor 2 is lessened, thus eliminating the need for a motor having high performance, and reducing the cost.

Title: Control method for stopping main shaft at fixed position
Inventor: SAKAMOTO MITSUO
IPC: G05D3/12
Filed: 1991-08-29
Abstract: PURPOSE:To stop a main shaft at a fixed position in a short time by setting a caught original point position in a position control loop, carrying on a decelerating operation with a velocity command kept at zero as long as the velocity command is higher than the present speed for position control, and carrying out the position control when the velocity becomes less than the present velocity. CONSTITUTION:When a fixed position stop command is received in a high speed revolution mode, a switch 2 is set at A and a zero velocity command is given to a velocity controller 3 for deceleration. A switch 9 is closed when the main shaft velocity V becomes less than a set velocity in a deceleration mode. Thus a switch 8 is closed by an original point signal PC and the present position is calculated by a computing element 10 based on the counter value set at the relevant time point. Then a multiplier 11 multiplies the deviation value set against a position command given from a target position generator 1 by the position loop gain KP. Thus the command velocity VP of a position loop is obtained. The spindle velocity V is compared with the velocity VP. When the latter velocity is higher than the former one, the deceleration is carried on with the switch kept at A. Then the switch 2 is set et B for execution of the position control when the velocity VP becomes less than the velocity V.

IPC: H01L29/866
Filed: 1989-09-22
Abstract: PURPOSE:To obtain a stable semiconductor device in which variation in breakdown voltage of a surface breakdown type Zener diode is small by so providing a n<+> type diffused layer as to surround an anode region between an anode electrode and a cathode electrode of the diode. CONSTITUTION:In a semiconductor device having a surface breakdown type Zener diode in which a n<-> type epitaxial layer 3 is grown on a p<-> type semiconductor substrate 1, a p<+> type diffused layer 5 formed in the layer 3 is used as a cathode region and a n<+> type diffused layer 6 formed in the layer 5 is used as an anode region, a n<+> type diffused layer 6a is so provided as to surround the anode region 6 between an anode electrode 8 and a cathode electrode 9 of the diode. Thus, since a Zener current flows to the p<+> type layer under the layer 6a by avoiding the layer 6a, a breakdown voltage is less affected by the influence of a stress of passivation, variation in the breakdown voltage is reduced, and its aging is suppressed to obtain a stable Zener voltage.

Filed: 1991-09-25
Abstract: PURPOSE:To eliminate consideration including code order at the time of generating the sequence processing code of a sequence device which successively and repeatedly processes the codes. CONSTITUTION:A sequence part 1 processes successively and repeatedly the codes. A outside signal input part 2 receives an input signal from an outside. An outside signal output part 3 transmits the output signal to the outside. Both first inside data part 4 and second inside data part 5 store input data or output data respectively at every code successive and repeated processing of the sequence part 1. Thus, output timings from the outside signal output part 3 are adopted as the same output timing regardless of the code order of the successive and repeated processing and consideration for code order at the time of generating the code is eliminated.

Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To save electric power largely, to improve the capacity to change the magnetic field gradient quickly, and to reduce possibility of claustrophobia feeling, noises, and nerve stimulus. SOLUTION: This magnetic field gradient coil 50 uses a return loop current path, a first part 51 pass current along a path in vicinity of an imaging volume to generate a magnetic field gradient in the imaging volume. A second part 53 at a point in a larger distance in the radius direction from the imaging volume passes current in the returning path in a direction reverse to that of the current in the first part 51 to reduce the floating magnetic field in the outside of the second part 53. The second part 53 is made far larger to confine the periphery of the magnetic field. The third part 55 connects a turn of the coil of the first part 51 with a turn of the coil of the second part 55. The third part 55 is partially arranged in the radial direction to connect first and second parts 51 and 53.  Consequently, the coil 50 is shielded and the floating magnetic field in the outside of the coil 50 is reduced using returning current.
