Title: Composite pitch conveyer in working line
Inventor: IDEMOTO YUKIHIRO
IPC: B23Q39/04
Filed: 1983-03-26
Abstract: PURPOSE:To enable works to be transferred with large and small pitches to shorten a length of a working line by arranging on a conveyer bar large pitch transfer carrier jigs with the large pitch and smaller transfer carrier jigs with the small pitch. CONSTITUTION:A conveyer bar 13 is rod-like, and to the upper surface thereof are secured fixedly carrier jigs for mounting works with common large pitch L and small pitch S. These carrier jigs consist of large pitch transfer carrier jigs 14 and small pitch ones 15 in which carrier jigs adjacent in the transfer direction are respectively spaced from each other by the large pitch L and the small pitch S, the carrier jig 15 being lower than the carrier jig 14. A base 16 is disposed below the bar 13 and on the upper portion of the base 16 are mounted pivotably lift arms 17. As the arms 17 pivot, connecting rods 26 advance to pivot all arms 17 so that the bar 13 pivots to the elevated position, and ascends.

Title: Valve assembly
Inventor: RARII KOUBAAN MITARU
IPC: E03D5/00
Filed: 1995-03-10
Abstract: PURPOSE: To obtain a valve assembly for controlling a flow of liquid flowing through a drain pipe from a sink within an aircraft. CONSTITUTION: When an aircraft is in an inactive condition on the ground, a fluid motor 20 presses a main valve part 22 lightly against a main valve seat 24. At this time, liquid within a drain pipe 12 can be leaked through the main valve part 22. However, at this time, the main valve part 22 works to prevent a reverse flow of odors through the drain pipe 12 into the cabin of the aircraft. When the aircraft is operating in the air, the motor 20 presses the main valve part 22 against the main valve seat 24 with sufficient force to seal the origin drain pipe 12 and prevent the leakage of liquid passing through the main valve seat 24.  When prescribed quantity of water is accumulated within the upstream drain pipe 12 from the main valve seat 24, a control assembly 28 of the motor 20 performs an operation so that the motor 20 may perform a work to separate the main valve part 22 from the main valve seat 24 to allow liquid to flow through the drain pipe 12 past the main valve seat 24.

Title: Optical pickup
Inventor: WADA KATSUTOSHI
IPC: G11B7/09
Filed: 1983-03-29
Abstract: PURPOSE:To prevent the generation of auxiliary resonance of a driving system which has influence upon a servo band by supporting an optical system with a revolving shaft in the position of the center of gravity and arranging two actuators in positions symmetrical with respect to the revolving shaft. CONSTITUTION:The whole of the optical system is supported by the revolving shaft provided at the intersection of a cross spring 11 which is the position of the center of gravity, and a pole brace 15 is connected to a movable part 5, and a pole brace 16 is connected to a housing 12. Two actuators 2 consisting of coils 2a and magnetic circuit 2b are arranged in positions symmetrical with respect to said intersection. Consequently, parallel forces except a couple of forces of the actuator are cancelled in the movable part to reduce a coefficient of excitation, and the force of inertia due to unbalance of rotation is not applied to the bearing because the rotation center is the position of the center of gravity of the movable part, and thus, the exciting force of auxiliary resonance, which has influence upon the servo band, due to the bearing is reduced to suppress auxiliary resonance.

Title: Indirectly heated cathode
Inventor: MISUMI AKIRA
IPC: H01J1/22
Filed: 1988-03-07
Abstract: PURPOSE:To reduce the evaporation wear of an electron emitting substance layer due to Joule heat and to and to compensate the lowering of the electron emitting performance by connecting a current compensation element electrically in parallel to a heater. CONSTITUTION:A current compensation element 8 connected electrically in parallel to a heater 4 of a cathode 2 is driven with a constant current heater power source 9. As a result, currents flow through both the heater 4 and the element 8 respectively in inverse proportion to the ratio of the respective resistances. The element 8 is constituted with a conductive material, Zr-Al alloy for example, having a characteristic of absorbing or reacting with a minute amount of gas in an electron tube and increasing its resistance with the lapse of time of operation of a cathode 2. When the current compensation element 8 is used, even if the electron emitting capability of an electron emitting substance layer 1 weakens with the lapse of the operation time of the cathode 2, the element 8 simultaneously absorbs or reacts with a minute amount of gas in the electron tube and increases its electric resistance. As a result, the current of a power source 9 flowing in the heater 4 increases to increase the heating capability of the cathode 2.

Title: Rack and pinion steering device
Inventor: YAMAGUCHI HIROTSUGU
IPC: B62D5/22
Filed: 1982-03-30
Abstract: PURPOSE:To detect whether the steering device is in the neutral position directly from the displacement of the rack shaft, by providing a switch element functioning through advance/back of the rack shaft. CONSTITUTION:When handling the steering wheel to move the rack shaft 3 in the axial direction, the tip of a rod 26a is pushed out of a recess 3b against the force of a spring 34, to move a slider 26 to the connector 30 side. Since the tip of the rod 26a will collide against the outercircumferential face of the rack shaft 3, the slider 26 will move to the connector side 30 by the depth of the recess 3b. Consequently the gap between a magnet 28 and a Hall element 31 is reduced, to increase the flux density to be applied on the Hall element 31 above the operating level thus to provide the output voltage. The output can be taken out from a terminal board 33 to detect whether the steering device is in the neutral position.

Filed: 1990-03-02
Abstract: PURPOSE:To surely take synchronization and to prevent occurrence of uneven revolution of a step motor by using a drive signal from a signal processing section so as to synchronize a vertical synchronizing signal with the step motor. CONSTITUTION:A horizontal synchronizing signal in a drive signal sent from a signal processing section 8 to a black/white solid-state image pickup element 2 is counted and based on the result of count of the horizontal synchronizing signal, a drive pulse signal fed to a step motor 4 is generated. Then the black/ white solid-state image pickup element 2 fetches a picture with a drive signal from the signal processing section 8 and the step 4 is driven based on the drive pulse signal generated by the drive signal. In this case, the horizontal synchronizing signal is counted to grasp the vertical synchronizing signal in correlation with the horizontal synchronizing signal thereby synchronizing the revolution of the step motor 4 with the vertical synchronizing signal. Thus, the step motor synchronously with the vertical synchronizing signal is surely driven.

The constant in specific equation is determined by a method of least squares from the BOD value and the measured DELTADO value. The values of the higher exactness are, therefore, obtd. as the number of the calibration times is larger.

Abstract: PURPOSE: To obtain the circuit provided with dual transistor(TR) elements in a current mirror form without a current hogging by providing a low impedance current source active TR element coupled in an emitter follower form to one collector node of the dual TR elements. CONSTITUTION: Dual phase splitter TR elements Q5, Q51 are connected by a current mirror form.

Title: Speed reduction gear
Inventor: ITOU HIROSHI
IPC: F16H49/00
Filed: 1982-03-31
Abstract: PURPOSE:To provide a large speed reduction with little noise even during a high speed rotation by forcedly bringing an inside cylinder formed of a thin rigid material into internally frictional contact with an outside cylinder at least at one spot and moving the contact point to be rotated by a pressure roller. CONSTITUTION:When an input shaft 1 is rotated, a pressure roller 2 eccentrically fixed to the input shaft 1 rotates on its axis and revolves along the internal peripheral surface of an outside cylinder 5 with an inside cylinder 3 pressed against said peripheral surface by a specified frictional pressure. At this time, a slippage in rotation is caused for a value made by multiplying a difference between the outside diameter of the inside cylinder 3 and the inside diameter of the outside cylinder 5 by pi. Therefore, when the input shaft is continuously rotated, a difference in rotation is produced in the inside cylinder 3 or the outside cylinder 5.
