Title: Optical equipment
Inventor: ISHIKAWA MASAAKI
IPC: G02B7/04
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To make the output torque of a driving unit large by providing a roller which has an abutting part for a rotating member on an oscillatory wave motor side and an abutting part for a manual coupling member having a smaller diameter than it. SOLUTION: The roller 22 has the 1st abutting part 22a with a large circumferential diameter that a coupling member 20 abuts against and the 2nd abutting part 22b with a small circumferential diameter that the manual coupling member 24 abuts against. An electrostrictive element 13 is applied with a voltage and the coupling member 20 is rotated on an optical axis. The roller 22 rolls along the end surface of the manual coupling member 24 and an output ring 21 also rotates on the optical axis. A cam ring 6 is driven through a projection 6b and a 1st group lens barrel 3 is driven along the optical axis. The rotation of a focus operation ring 9 is transmitted to the manual coupling member 24. The roller 22 rolls along the end surface of the coupling member 20 while rotating around an axis 21a on the output ring 21.  The output ring 21 also rotates on the optical axis and the cam ring 6 is driven through the projection 6b.

Title: Rotor assembly of power generator
Inventor: YAN-YUN YOO
IPC: H02K15/16
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To keep the unbalance during rotation small and improve the characteristic of power generator through restraining deformation and eccentricity. SOLUTION: This rotor assembly is composed of a shaft 1, having a set of grooves 2 at both ends and a knurling portion 3 and a rotor having a boss 6. The knurling portion 3 is formed as the part where many projected portions are formed. The boss 6 is formed as a part projected to the enter axis of the rotor and has a height capable of sizing. The shaft 1 and rotor can be coupled rigidly, by having the shaft 1 inserted into the axial hole of rotor and then burying a part of the boss 6 to the knurling portion 3 and groove 2 through the sizing. Since the shaft 1 is not inserted forcibly to the rotor, deformation and eccentricity will not be generated in the shaft 1 and the rotor.

Abstract: PURPOSE:To reduce a force required for driving, by fitting a piezoelectric element on an elastic unit, and by placing a stationary unit on the surface of frictional contact to support an object. CONSTITUTION:An object moving device is composed of a stationary unit 3 formed with a piezoelectric element 1 and an elastic unit 2 which are fitted on each other, and an object 4 fixed on the unit 3. In order to fix the stationary unit 3 on the object 4, a bearing stand 5 is used and is fixed on the side of the piezoelectric element 1 so that oscillation cannot be transmitted, and is formed so that the oscillation may be transmitted better to a frictional contact surface 6 with which the elastic unit 2 comes in contact. When electric signal is applied to both the ends of the piezoelectric element 1 of the object moving device formed in this manner, then a force required for moving the object 4 is reduced.

Title: Telephone number retrieval device
Inventor: ETSUNO YUKO
IPC: H04M1/21
Filed: 1991-11-14
Abstract: PURPOSE:To expand the possibility of telephone number retrieval by providing a synonym dictionary and displaying a telephone number corresponding to an index word. CONSTITUTION:When a user who wants to know the telephone number of the 'naika' (internal department) of, for example a hospital inputs the pronunciation of 'naizou' (internal organs) on an input device 1, the input is converted into a Chinese character and Japanese syllabary mixed sentence 'naizo', which is stored in a conversion result storage part 31. Then retrieval is carried out by referring to the contents of the conversion result and the contents of the conversion result storage part 63, but 'naizo' is not present among the sections and names of a telephone number dictionary 63 in this case, so a synonym retrieval part 75 retrieves the synonym dictionary 65. Then the character string 'naizo' is found in a synonym group constituted having 'naika' as its index word, so a found word replacement part 77 replaces the character string 'naizo' with the index word 'naika'. This 'naika' corresponds to a subsection of a section of the telephone number dictionary 6, so only the telephone number of the section of this 'naika' is outputted and displayed.

Filed: 1990-11-05
Abstract: PURPOSE:To obtain an inexpensive three-dimensional Y/C separation circuit by storing a base band signal whose band is narrower than that of composite video signal in frame memories and generating a chrominance signal. CONSTITUTION:The base band signals demodulated by demodulation means 13a and 13b are stored in the frame memories 14a and 14b, and a difference between the base band signals and a base band signal prior by one frame, which is stored in the frame memories 14a and 14b, is operated. The outputs of the arithmetic means 15a and 15b are balance-modulated by the frequency of a color carrier in a modulation means 17 so as to generate the chrominance signal and the difference between the composite video signal and the chrominance signal generated by the modulation means 17 is operated so as to extract a luminance signal (Y signal). In such a case, the band of the base band signal to be demodulated is narrower than that of the composite video signal. Thus, a sampling frequency sampling the base band signal can be low and the capacity of the frame memory can be small.

Filed: 1990-11-05
Abstract: PURPOSE:To easily turn a circuit on or off via a manual action by providing a bimetal plate electrically connecting a contact terminal board and a lever inserted with an energizing force between a moving contact and the contact terminal board. CONSTITUTION:When the off-projection l9a of a lever is pushed, a tongue section 19e is rotated centering on a support hole 19d and inserted between the contact section 12b of a contact terminal board 12 and a moving contact 15 to cut off a circuit. The thrusting force of the off-projection 19a of the lever is quickly decreased from the initial thrusting force at its peak, when the initial thrusting force or above is applied, the thrust speed of the off-projection 19a is quickly increased, then the off-operation is completed. At the time of an on-action, the returning force of a bimetal plate 14 tends to extrude the tongue section 19e of the lever along a curve via the moving contact 15, thus the thrusting force of an on-projection 19b becomes zero instantly, and the on-operation is completed. An optional circuit can be turned on or off.
