Title: Method of driving piezoelectric motor, piezoelectric motor and head driver for disk storage device
Inventor: KUMAGAI TOMOKO
IPC: G11B21/02
Filed: 1988-09-28
Abstract: PURPOSE:To conduct stable fine displacement even by the use of very small voltage, and to improve the accuracy of final positioning by applying DC voltage having mutually reversed polarity to a pair of piezoelectric elements. CONSTITUTION:When AC voltage having phase difference is applied to a pair of piezoelectric elements 2, 3 of a piezoelectric driving unit 1, a driver 6 conducts an elliptic periphery motion, and a body to be driven 7 can be displaced and driven. When DC voltage having mutually reversed polarity is applied to a pair of the piezoelectric elements 2, 3, on the other hand, fine drive is enabled. Accordingly, the body to be driven 7 is displaced and driven largely by AC drive at the time of normalcy, and AC drive is changed over to DC drive at the time of final positioning, thus improving the accuracy of positioning.

Title: Paper-feeding mechanism for printer
Inventor: TAJIMA AKIO
IPC: B41J15/04
Filed: 1985-10-30
Abstract: PURPOSE:To automatically introducing a recording paper through a simple operation, by providing a cam part with three positioning cam surfaces having different radii for shifting a lever to three rocking positions through following-up of a cam follower, and a cam surface for pressing a switch for a paper-feeding motor. CONSTITUTION:When a recording paper skewly inserted between a platen 1 and a pinch roller 2 is to be adjusted to a correct pose, a knob is turned counterclockwise, whereby a cam follower 16a is brought into elastic contact with a positioning cam surface 31d, so that a support shaft 15 is turned further counterclockwise, and a projected part support 18c of a roller support 18 is engaged to a projected part 17c by an energizing spring 19. In this case, since a fulcrum is located extremely close to the line of action of the spring force of the spring 19, the pinch roller 2 makes elastic contact with the platen 1 with a weak pressure. When the skewing of the recording paper P is corrected and the knob is returned to an initial position to increase the pressure exerted by the pinch roller 2, the paper P in the correct pose is fed in. Accordingly, automatic introducing of the recording paper can be performed simply by turning the knob connected to a platen bearing 3.

Title: Fuel assembly and lower tie plate
Inventor: YANAGI YOSHIHIKO
IPC: G21C3/33
Filed: 1990-09-13
Abstract: PURPOSE:To suppress the leakage of a coolant by a method wherein the coolant is made to flow through a coolant leak passage and a force drawing the lower end part of a channel box toward a lower tie plate is generated by the action of the flow of the coolant passing through the coolant leak passage. CONSTITUTION:A coolant hole 18 positioned in the outermost periphery makes a coolant flow out into a part above a coolant leak passage 17 formed between the lower end part of a channel box 8 and a lower tie plate 4 and reduces the pressure in that part. Thereby a leak driving force of the coolant is reduced and the leakage is suppressed. By a force drawing the lower end part of the channel box 8 toward the lower tie plate 4, besides, the amount of deformation of the lower end part of the channel box 8 toward the outside is held down. By an effect of multiplication of this action of holding down the amount of deformation by the action of the coolant hole 18, the leakage of the coolant is suppressed more effectively. According to this constitution, the leakage of cooling water from between the channel box 8 and the lower tie plate 4 can be suppressed.

Filed: 1990-09-14
Abstract: PURPOSE:To utilize a transmitter-receiver efficiently without waste in which upper and lower channel capacity in all zones is balanced by grouping mobile stations so as to form a position registration area different from each group. CONSTITUTION:For example, a mobile station 115 sends a position registration request signal to a base station 104, which allows a home memory station 102 to revise a position code of the mobile station 115 via a mobile communication control station 101. When a communication request comes from a stationary network side to the mobile station 115, the position registration area in which the mobile station 115 is resident is recognized from a position code of the home memory station 102 and a simultaneous call signal from the base station 104 in its area is sent to a radio zone 110. Then a reply from the mobile station 115 in the area is received to specify a radio zone in which the mobile station 115 is resident for the connection control. Thus, the usage without waste in which upper and lower channel capacity is balanced in all zones is attained and the transmitter-receiver is installed efficiently.
