Title: Zoom lens barrel
Inventor: ATSUTA RIICHI
IPC: G02B7/10
Filed: 1986-09-30
Abstract: PURPOSE:To prevent an increase in the size of a lens barrel and to obtain the lens barrel suitable for the reduction in weight by providing two moving frames thereto and assembling the two moving frame as single layer structure. CONSTITUTION:A cam barrel 12 is turned cooperatively with the rotation of a pinion in a telephoto state in which the 1st, 2nd moving frames 13, 14 are extended. Pins 22a, 22b are thereby pushed into cam holes 12a, 12b, by which the moving frame 13 is moved rightward. The pins are similarly pushed by the cam holes and the moving frame 14 is also moved rightward. The pins 22a, 22b are guided by the guide holes 11c, 11d of a stationary barrel 11 during the course of this movement and the moving frame 13 moves in the non-turning state in the barrel 11. A gear 24a of a rotating barrel 24 screwed to the front end of the moving frame 13 is held engaged with the focusing pinion and is moved rightward in this state. The moving frame 14 moves in the non-turning state as the pins are guided by the guide holes of the barrel 11. The circular curved surface part thereof moves in the notched hole of the moving frame 13. The motor stops running when the turning of the cam barrel 12 progresses.

Title: Output buffer circuit
Inventor: OKAZAKI NOBUMICHI
IPC: H03K19/0175
Filed: 1984-10-31
Abstract: PURPOSE:To offer a circuit with less current noise by forming an output from a midpoint of the 1st and 2nd transistors (Trs) connected in series with complementary operation and providing a control circuit between the gate and drain of the 1st or 2nd Tr. CONSTITUTION:A TrQ3 is turned on by an NAND signal Sf during a prescribed period X at the trailing of an input data signal Sa, the gate-drain of a TrQ2 is short-circuited and the TrQ2 acts like a diode. Thus, the TrQ2 is turned on until a potential at a connecting point q1 reaches a thresho 1d level Vth of the TrQ2. After the period X is elapsed, the TrQ4 is turned on, the level of the gate of the TrQ2 reaches a power voltage VDS and the TrQ2 keeps the on-state during the period Y. In this case, since the drain potential of the TrQ2 is Vth, a current flowing to a grounding line 9 is small. Thus, current noise is suppressed.

Title: 2-input logic circuit
Inventor: SHIMIZU SHIN
IPC: H03K19/0948
Filed: 1990-08-30
Abstract: PURPOSE:To attain a high integration and a high speed by constituting a NAND circuit or a NOR circuit of only two MOSFETs. CONSTITUTION:A p-type MOSFET Q1 and an n-type MOSFET Q2 of surface channel type are provided, and respective gates are joined to form the pn junction, and the gate of one of them is connected to a first input terminal 10 through a first resistance R1, and the gate of the other is directly connected to a second input terminal 12. Drains of the p-type MOSFET Q1 and the n-type MOSFET Q2 are connected with a second resistance R2 between them, and either side of the second resistance R2 is connected to an output terminal 14. Consequently, two MOSFETs are operated as a ratioless inverter when only one of them is turned on, but a ratio type output is obtained by the operation resistance of MOSFETs and the second resistance R2 when both of MOSFETs are turned on. Thus, the number of transistors is reduced to obtain a high speed and a high integration.

Title: Fet amplifier
Inventor: KATO KEIICHI
IPC: H03F1/30
Filed: 1985-10-17
Abstract: PURPOSE:To keep the characteristic to an amplitude frequency characteristic adjusted at room temperature over a wide temperature range by connecting thermosensitive resistance element in series or parallel with at least one resistor of two resistors dividing a negative voltage fed to a gate terminal. CONSTITUTION:The thermosensitive resistance element 5 is connected between a fixed resistor 3 and a negative power source 6. When the ambient temperature changes, since the resistance of the element 5 changes, a negative voltage VGS of a gate terminal 10 changes, the kind of the thermosensitive resistance element 5 is selected from thermisters of positive/negative temperature coefficients and the resistance value is selected to cancel the change in the DC parameter of a GaAs FET 1. Thus, the change in the amplitude deviation is decreased over a wide temperature change.

Title: Multi-layer reflection preventing film
Inventor: NAKAMURA HIROSHI
IPC: G02B1/115
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To provide an oblique incident multi-layer reflection preventing film effective against the light having a large incidence angle in an ultraviolet region by laminating high-refraction factor layers and low-refraction factor layers in turn from the incidence medium side in sequence, making the high-refraction factor layers equal to each other in optical thickness, and making the low- refraction factor layers equal to each other in optical thickness. SOLUTION: High-refraction factor layers 1 and low-refraction factor layers 2 are laminated in turn on a substrate 3 from the incidence medium side. When the number of laminations is an odd number, the high-refraction factor layer 1 is kept in contact with the substrate 3. When the number of laminations is an even number, the low-refraction factor layer 2 is kept in contact with the substrate 3. The high-refraction factor layers 1 are individually laminated at the same optical thickness, and the low-refraction factor layers 2 are individually laminated at the same optical thickness. The adjacent high-refraction factor layer 1 and low-refraction factor layer 2 have the optical thickness of a constant value, and this multi-layer reflection preventing film has a periodic structure. This film has a reflection preventing effect in the incidence range of 70 deg.<=θ<=80 deg. against the p-polarized light in the wavelength range of 150 nm<=λ<=250 nm.

Title: Sheet feeding device and image forming device
Inventor: KONDO AKIHIRO
IPC: G03G15/00
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To provide a sheet feeding device silent and excellent in sheet feeding performance. SOLUTION: Only the uppermost sheet of a bundle of sheets is separated by the pawl 6 of a corner separator 5 so as to be forwarded, and the forwarded sheet S is guided by a sheet guide 7 to a carrying path 11 abruptly raised upward against the forwarding direction. And the sheet guide 7 is so formed up that it is inclined downward to the lower side under the extension line in the sheet forwarding direction from the carrying path 11. By this constitution, since the magnitude of flection of the sheet S to be fed to the sheet carrying path 11 from the sheet guide 7, can be made small, the sheet can be fed smoothly.  In addition, the provision of a sheet feeding guide piece 8 by which the corner separator 5 guides the rear end Sa of the sheet toward the sheet guide 7, thereby allows the quantity of flexural deformation of the rear end of the sheet to be made small, accumulated energy at the rear end of the sheet thereby becomes low, and sound caused by the collision of the rear end of the sheet with the sheet guide can thereby be made low.

Title: Balancing mechanism of cantilever
Inventor: KOBAYASHI YOSHIROU
IPC: F16F15/28
Filed: 1982-12-29
Abstract: PURPOSE:To keep each portion such as a driving portion and so on from unnecessary load produced by balancing means by fixing a chain or wire through a balancing spring to a supporting point for hanging up a cantilever. CONSTITUTION:When with a chain 9 extended, an adjust nut 8 is adjusted, so that balancing force is worked upon the other end 1a of a cantilever 1 by a plate spring 7, the spring force for pushing down the other end 1a of the cantilever 1 with the plate spring 7 works equally to the weight of the general balance weight W3. As both ends of the chain 9 are fixed to the same rigid body integral with the cantilever 1 to be endless, when the cantilever 1 and a supporting point P are raised, the position of the plate spring 7 is also raised by the same distance. Therefore, there is no fluctuations in load of the chain 9, and the spring force of the plate spring 7 is not changed, so that the spring force W3 for balancing always works. Thus, a problem such as an increase in load of a driving motor or a hanging chain can be avoided, and the mechanism can be disposed above the second floor to reduce the installation space for the balancing means.

Title: Base isolation device for building
Inventor: SHIYUUYOU MASAO
IPC: E04B1/98
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To absorb the lateral motion of a foundation and ensure the prevention of the dislocation of a contact part between the foundation and a sill by applying the constitution that a pair of upper and lower rubber base isolation mats having a plurality of elastic bodies between separated opposite faces are laid between the foundation and the sill. SOLUTION: Upper and lower rubber base isolation mats 6 as a pair are jointed to each other with a plurality of approximately columnar elastic bodies 8. In this case, the elastic bodies 8 are arranged approximately evenly near the roughly entire surface of the opposite faces of the upper and lower base isolation mats 6, with gaps formed for preventing the interference of the adjacent elastic bodies 8 with each other, even upon the occurrence of the compression thereof due to a vertical load. Also, projections 10 formed on the upper surface 6a and the lower surface 6b of the upper and lower base isolation mats 6 are coupled to circular holes 2a and 4a formed on a foundation 2 and a sill 4.  According to this construction, each of a plurality of the elastic bodies 8 is deformed to properly absorb earthquake motions transmitted from the foundation 2 to the sill 4 against lateral motions along all horizontal directions. Also, the base isolation mats 6 come in contact with the foundation 2 and the sill 4 over a wide area, thereby preventing the dislocation of a contact part between the foundation 2 and the sill 4 and maintaining the closely adhering state thereof.

Title: Conference system
Inventor: TOTOKAWA NORIBUMI
IPC: H04M3/56
Filed: 1982-12-28
Abstract: PURPOSE:To send the voice of a speaker in a conference to respective participators in the conference in common in one direction by using a multiple connection function in a time sharing network. CONSTITUTION:Respective extensions A-N can access the participators in the conference by sending conference request specific Nos. and the extension Nos. After accessing the required participators, the up highway of an extension (e.g. B) is multiplly connected to the whole down highways and a prescribed sound source (e.g. the 2nd dial tone SDT) is connected to the down highway of the extension B. Another extension to be required speaking can send the voice to all other participators in the same manner as the extension B by hooking (switching of the conference) the telephone set. Therefore it is unnecessary to use a voice mixing trunk for realization of the conference, so that economical efficiency is obtained. Further, terminal number to be connected is not limited, so many extensions can communicate in the conference.

Title: Electron beam control system
Inventor: SHIMOI NORIHIRO
IPC: H01J29/58
Filed: 1998-08-18
Abstract: PROBLEM TO BE SOLVED: To reduce the spot size of an electron beam on an irradiation surface to improve the resolution in connection with an emission angle (a beam divergence angle) of the electron beam emitted from an emission part. SOLUTION: This electron beam control system has a focus magnet 3 which forms a magnetic field for focusing an electron beam on a beam trajectory axis between an emission part and an irradiation surface. An intensity distribution of the magnetic field formed on the beam trajectory axis by the focus magnet 3 is controlled to have an asymmetric shape such that its intensity peak (p) is displaced toward the irradiation surface in a beam trajectory axis direction. Thereby, because a spot size of the electron beam on the irradiation surface can be lessened, the aberration of the electron beam is suppressed so that flare is reduced. As a result, a contour of an image is sharpened and the resolution can be improved.
