Title: Automatic aviation device of rotary wing aircraft
Inventor: YAMAKAWA EIICHI
IPC: B64C27/00
Filed: 1992-03-09
Abstract: PURPOSE:To have compatibly an excellent responsiveness in speed control and the safety by furnishing a plurality of calculating means to set the acceleration/deceleration in accordance with the deviation of the current speed value from its target value, and therewith calculating the target values for the pitch attitude angle as one trait among the attitudes of the fuselage of a rotary wing aircraft. CONSTITUTION:The aviation control system of a helicopter is provided with a plurality of calculators 105, 106, which calculate the pitch attitude angle target values in order, for example, to control the pitch axis on the basis of the outputs from a speed sensor 102 and an acceleration sensor 103 and from a speed target value calculator 104 in accordance with a control panel 2. Therein one of the calculators 105 makes computation to generate a target value for changing the speed for quick approach to the target value in case difference between the target value and current value is large, while the other calculator 106 makes computation to generate a target value for speed stabilization for convergence to the target value without risk of overshoot in case the difference is small. Thus a large acceleration/deceleration is generated in case the difference is large and a small acceleration/deceleration is generated in the opposite case.

Title: Interference testing device
Inventor: TAKE YOSHIHIKO
IPC: H04B17/00
Filed: 1988-03-03
Abstract: PURPOSE:To attain the various kinds of interference tests even when a person to be interfered flies by an aircraft, etc., at high speed by arbitrarily changing the period and speed of the scan of an antenna beam from an antenna, which has directivity, in an arbitrary direction or to a whole circumference. CONSTITUTION:A controller 13 of an interference testing device 1 sets the respective types of parameters such as scanning speed, scan period and a scan angle, etc. A directivity controller 12 executes scanning control to correspond to the above mentioned parameter by control from the controller 13. An antenna 14 has the directivity and an interfering wave is emitted into the air by the control from the directivity controller 12. The interfering wave to be received by the person to be interfered 2 goes to a pulse-shaped AM signal 8. When the receiving system of the person 2 is an AM receiving system, interference is executed with the AM signal 8. In such a case, by chaining the scanning period and scanning angle, etc., with the controller 13, the various kinds of the AM signals 8 are equivaltently generated and the interference test is executed.

Title: Laser graphic display device
Inventor: KURITA YOSHITAKA
IPC: G06F3/153
Filed: 1989-03-03
Abstract: PURPOSE:To enable even a beginner operator to easily produce the dot data in a short time by using a personal computer to automatically compress the one-stroke write data used for the laser graphic display. CONSTITUTION:A personal computer 8 contains a frame buffer memory part 9, an extracting part 10 which extracts the prescribed one-stroke write data out of the bit map data, a dot data process production part 11 which compresses the one-stroke write data and produces the dot data, and a D/A converter 12 which converts the dot data into the analog data and outputs this data to a laser beam scanning part 16. The part 11 identifies a corner part A and a curve part B out of a thin line pattern to keep the dot coordinates included in the parts A and B in a comparatively dense state and to keep the dot coordinates included in other straight line parts in a comparatively rough state respectively. As a result, the pictures are reproduced with high quality at a part having the comparatively high density. Meanwhile the data are effectively compressed over an entire straight line part owing to its comparatively low density. Thus no expertness is required and the working time is shortened.

Title: Sleeve
Inventor: SHOJI SETSUO
IPC: B21D53/10
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To surely hold a ferrule and to reduce the occurrence of dust by providing a projected line spirally or so as to elastically deform on the inner peripheral face of a substantially cylindrical member. SOLUTION: In this sleeve 10, three projected lines 12A-12C are extended and provided on the inner peripheral face 11a of a substantially cylindrical member 11 continuously, spirally at regular intervals from one end to the other end of the cylindrical member 11 and the circular-arcuate projected lines are held in linearly contact with the ferrule so as to surround the outer periphery of the ferrule. In such a sleeve 10, holding force in the withdrawal direction of the ferrule becomes larger compared with the parallel projected line in the axial direction by spirally providing the projected line and the lining-up stability is improved. Since the ferrule is held with linear contact, the occurrence of dust is reduced and a coupling loss is decreased.

Title: Hydraulic motor
Inventor: WADA AKIO
IPC: F03C2/08
Filed: 1980-04-19
Abstract: PURPOSE: To provide an output of a low speed and high torque by a method wherein the number of teeth of planetary gear for producing an output power or of a follower sun gear to which inner surface are contacted said planetary gears are made to be different by one or more teeth from that of the rotor or stator.  
     CONSTITUTION: Since both the rotor 3 and the planetary gear 18 for producing an output power are fixed to both ends of the eccentric shaft 7 with the same eccentricity e, a cooperative planetary movement may be performed on the same planetary orbit. The number of teeth of the output planetary gear 18 or the follower sun gear 20 is made to be different by one or more from that of the rotor 3 or the stator 1. Thereby, the speed may further be reduced and an output of a high torque may be produced at the output shaft 21. Further, as in a conventional type of the hydraulic motor, since it is not required to connect the rotor 3 with the output shaft 21 through a free oscillating universal coupling, no problem is found for an accuracy or an antiwear characteristic of the rotor and the output shaft, further their structure may be simply formed.

Title: Ballpoint pen
Inventor: KOBAYASHI SEIICHI
IPC: B43K7/10
Filed: 1994-02-28
Abstract: PURPOSE:To prevent ink from flowing backwards and forwards under the state that a pen is postured upwards and downwards by method wherein a valve chamber, which communicates with the rear end of a tip, in the rear of which a ball valve is loosely fitted and at the rear end of which a ball bearing seat is provided, is provided at the axis center line of a joint under the condition that a piece, at the rear end of which ink guiding grooves are provided, is fixed between the front of the ball valve and the rear end of the tip. CONSTITUTION:Under the state that a tip 5 is postured downwards, a ball valve 15 opens a guide hole 20 by abutting against the rear end of a piece 16 so as to run the ink, which reaches a value chamber 13 from an ink storing tube 4 through the guide hole 20, is guided through the ink guiding grooves 16a and the hole 16b of the piece 16 to the rear end of a tip ball 5a. In this state, the tip ball 5a is brought into close contact with the inner edge of a tip holding part by being pressed with a bar shaft part 18, resulting in preventing ink from flowing forwards. Then, through the minute retracting of the tip ball 5a by the pressure of a pen, ink becomes possible to flow out. Further, under the state that the tip 5 is postured upwards, the ball valve 15 comes into close contact with the ball bearing seat 14 of the valve chamber 13 so as to tightly seal the guide hole 20, resulting in preventing the ink from flowing backwards, even under the state that no ink is present just below the tip ball 5a due to the writing in upward posture.
