Title: Stern tube bearing device
Inventor: IKEUCHI AKITAKA
IPC: F16C32/06
Filed: 1986-03-27
Abstract: PURPOSE:To support a propelling shaft invariably in the best condition by providing a static pressure pocket at the rear region of a stern side stern tube bearing and approaching the pressure and displacement between the nearby bearing and the propelling shaft invariably to reference values. CONSTITUTION:During the heavy weather or the like, when a propelling shaft S receives an external force which is different from the normal one via a propeller and tends to be displaced, it is detected by a pressure sensor 10 and a displacement sensor 11 near a static pressure bearing pocket 2 provided at the rear region of a stern side stern tube bearing 1. An arithmetic control circuit 12 compares these signals with pressure and displacement reference values primarily under the optimum support condition and feeds the oil from a pump 5 to the static pressure pocket 2 via a flow/pressure regulator value 6 so as to reduce the difference and controls so that the pressure and displacement at the bearing 1 approach normal reference values. Accordingly, the propelling shaft is supported in the best condition, the one-sided contact of the bearing section is avoided, and the breakage and friction of the propelling shaft are remarkably decreased and its life can be extended.

Title: Irreversible power transmission device using internal gear with small gear difference
Inventor: KUSAKA SUSUMU
IPC: F16H35/00
Filed: 1979-06-01
Abstract: PURPOSE:To get an irreversible power transmission device which inhibits transmission of power from an output shaft to an input shaft, by fitting eccentric gears to a crankshaft as an input shaft and making a profile shifted internal gear engaged with the external circumference of the eccentric gears. CONSTITUTION:When an input shaft 2 is turned, eccentric gears 3a, 3b fitted swivel to cranks 2a, 2b through bearings 8a, 8b respectively, are also turned. Since the gears 3a, 3b are restricted by a pin 5 to make rotary movement as a total, they can make only vertical and horizontal movements and 4 secondary radial rotation (partial rotations) equal to the crank of the input shaft 2. As a result, rotation of an output shaft 6 is reduced through a profile shifted internal gear 4 having a small difference in the number of tooth compared with the said gears. When the output shaft 6 is forced to turn, gears 3a, 3b are inhibited to turn as a total due to the pin 5 and a frame 1 and the input shaft 2 is not turned.

Title: Metalli strip cold rolling method
Inventor: ITO HIROYUKI
IPC: B21B1/22
Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To prevent a heat streak by continuously measuring a cold rolling plate thickness on the mill inlet side, detecting the start of an abnormal plate thickness section whose deviation to a set value deviates from an allowable range, decreasing a rolling speed, and detecting the completion of the section to restore the rolling speed. SOLUTION: At the time when a thick plate section 1A whose plate thickness deviation on the first stand inlet side, which is continuously measured by a plate thickness meter in the longitudinal direction of the strip metal 2, exceeds an upper limit value αH, is detected before the thick plate section 1A is bit by a mill, the rolling speed is decreased from a normal set value β to a set value γH corresponding to the thick plate section 1A, and rolling is performed. The heat streak caused by a high reduction of area in the first stand, can be prevented. When the plate thickness deviation on the first stand inlet side exceeds a lower limit value αs, the rolling speed is decreased from the set value β to γs corresponding to a thin plate section 1R and the rolling is performed.  An oil film quantity in roll bite is decreased, a frictional force becomes high, and a slip in the thin plate section 1B can be prevented.

Title: Direction indicating device
Inventor: HOSONO MIKIO
IPC: G01S3/42
Filed: 1981-05-07
Abstract: PURPOSE:To ensure an assured indication for the arriving direction of an electric wave, etc.  through a combination of the directional and nondirectional antennas, etc., by controlling a pulse  motor with generation of a pulse that has the number of pulses and the phase according to the  amplitude/phase detection signal based on the received signal. CONSTITUTION:The induced voltage of a directional loop antenna 1 is synthesized 7 with the induced voltage of a nondirectional antenna 2 whose phase is reversed through a balanced modulator 10 and based on the cycle of modulated wave sent from a modulated wave generator 14 to be  supplied to a receiver 11. Based on the output of the receiver 11, the voltage proportional to the  arrived electric wave and the voltage proportional to the relative direction of the antenna 1 as well as the direction of the arrived electric wave are generated from an amplitude amplifier 12  and a phase comparator 13. Accordingly the pulses having different number of pulses and phase  are generated from a variable pulse generator 15. These pulses are applied to a direction indicator  3 as well as to windings A6 and B7 of a pulse motor 4 that controls the antenna 1 to give a control to both the rotating speed and the rotating direction of the motor 4. Thus an accurate indication is made possible for the arriving direction of an electric wave, etc. and according to a rotation free from any hunting and its discontinuation.

Title: Small switch
IPC: H01H1/42
Filed: 1992-03-26
Abstract: PURPOSE:To enable fabrication capability to be improved with clamp pressure increased for movable contact sections by forming and projecting the sections toward the side of stationary contact sections in such state as dislocated from each other for avoiding opposed arrangement. CONSTITUTION:A pushbutton is so laid as to stride over a movable contact spring 5, and the projection 8 of a resin body 1 having insertion molded terminals 2 and so forth is coupled to the recess of a resin case. Also, movable contact sections 6 and 6 are projected toward stationary contact sections 4 in such a way as dislocated from each other for avoiding opposed arrangement. The spring 5 is shifted with pressure by pressing the pushbutton, and the contact state of the sections 6 and 6 with the upper and lower stationary contact sections 4 and 4 is thereby selected to open and close a contact. In this case, one section 6 dislocated for avoiding the opposed arrangement is caused to substantially project for ingress into the base of the other section 6, thereby enabling clamp pressure to be increased for clamping the sections 4 between the sections 6 and 6. Also, arm pieces 5a do not need to be bent toward the sections 4, and fabrication capability for a switch can be improved, with contact pressure increased.
