Title: Apparatus for analyzing resistance circuit network
Inventor: SHIMADA KOICHI
IPC: G01R27/02
Filed: 1988-06-20
Abstract: PURPOSE:To prevent transition current when specimen incorporates a capacitive component and to perform measurement even if the specimen includes a short- circuiting element without trouble, by supplying preparation current under the state wherein ammeters are bypassed in starting measurement. CONSTITUTION:When a capacitive component is included in a specimen X, transition current flows through ammeters I. It takes a long time to attain a balanced state. Therefore, during the preparation period at the beginning of the measurement, a first switch S11 in a resistance measuring circuit I1 and a second switch S21 in a resistance measuring circuit I1 are both turned ON. The current is supplied to the specimen X without through the ammeters I1a and I1b. In this way, a time until a steady state is achieved is shortened. When the specimen is a short-circuiting element, the current through a current limiting circuit IL1 is increased, but a constant voltage element VL1 becomes ON. Since the terminal voltage of a power source is kept at a constant value, measurement can be performed without trouble.

Filed: 1990-06-12
Abstract: PURPOSE:To prevent a rightward or a leftward inclination of a shelf, enable the shelf to be moved and further prevent a shelf device from hindering a storage of food at a lower part by a method wherein both gear shafts and both spur gears are rotated under an operation of a double-axis electric motor and the shelf and a frame are moved up or down. CONSTITUTION:When a control switch 6 is turned on, a geared shaft 4 connected to a shaft of a double-axis electric motor 7 is rotated, thereby spur gears 5 at both ends of the geared shaft engaging with a rack 13b are rotated, and a shelf 1 and a frame 2 are moved up or down while being kept horizontal by spur gears concurrently rotated up or down on the right and left racks. Since a sliding member 3 moving up or down within a sliding groove 13a can also slide smoothly without being inclined, no substantial load is applied to the double-axis electric motor. Due to this fact, a movement of the shelf can be operated only with the operation of the control switch and further it is possible to make a size of the device for moving the shelf of the electric motor or the like small. The moving device does not become a hindrance for a storing of food at the lower part.

Filed: 1995-06-20
Abstract: PURPOSE: To accurately detect the tilt of an input document without user's intervention by detecting the tilt quantity of inputted image information according to projections detected from two determined partial image areas. CONSTITUTION: An image which is optically read by a scanner 108, etc., is inputted. The inputted image is stored in a RAM 103. To find the tilt quantity of a document in the input image, an inspection area is acquired in the input image. The image in the obtained inspection area is analyzed to decide the document direction in the area. The tilt quantity of an area wherein the document direction is judged to be lateral is found by a tilt quantity detecting method for lateral writing and the tilt quantity of an area which is judged to be a longitudinal writing area, on the other hand, is found by a tilt quantity detecting method for longitudinal writing. Thus, the tilt quantity is found and the input image is so deformed as to remove the tilt of the document. Namely, the image is rotated around the center of gravity of the input image by the tilt quantity in this case.

Abstract: PURPOSE:To prevent a cassette from becoming afloat by setting the inclination of an inclined tooth part of a ribbon feed shaft to be set facing a direction in which a component of force in a bearing where a ribbon cassette is pressed against a cassette attachment part when a ribbon drive shaft is rotated in a ribbon feed direction under the engaged state of the inclined tooth part. CONSTITUTION:When a ribbon cassette 16 is attached to a ribbon vibrator 12, a spiral gear 76 of an inner tooth part formed on a ribbon feed shaft 74 of the ribbon cassette 16 is engaged with a spiral gear 50 of an outer tooth part formed on a ribbon drive shaft 39 of the ribbon vibrator 12. If the drive shaft 38 is driven to rotate for ribbon winding under this state, the ribbon feed shaft 74 receives a transferred force F directed obliquely downward at right angles with the surface of a spiral gear 50 from the gear 50 of the ribbon drive shaft 38, on the spiral gear surfaces 50,76. This transferred force F is divided into a horizontal component F1 which rotates the ribbon feed shaft 74 and a vertical component F2 which holds a ribbon cassette 74. Thus the ribbon cassette 16 is prevented from becoming afloat from the ribbon vibrator 12 due to the downward vertical component F2.

Title: Indirect hot-line gripper
Inventor: FURUIKE TOMOYUKI
IPC: H02G1/02
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To facilitate the locking and unlocking operation easily by installing a locking pin member, which locks a unidirectional rotation mechanism at locking and unlocks it and allows an operation lever to rotate in either a gripper closing direction or opening direction at the time of unlocking. SOLUTION: When a locking mechanism 40 allows an operation lever 31 to be rotated in a closing direction of a gripper 20, it prevents the operation lever 31 to rotate in the gripper opening direction (to rotate in a direction opposite to that shown by the arrow A) by means of a unidirectional rotating mechanism 42. A lock pin 43 locks the unidirectional mechanism 42 at the time of locking and unlocks it and allows the operation over 31 to rotate in either the gripper closing or opening direction at unlocking. Due to this structure, locking and unlocking operation can be made easily with only one hand for gripping the operation lever 31.
