Title: Biquad type secondary band-pass active filter
Inventor: KANEKO KAZUHIRO
IPC: H03H11/12
Filed: 1984-05-31
Abstract: PURPOSE:To reduce the size and power consumption of the filter by feeding the output signal of a primary low-pass filter to the inverted input terminal of an operational amplifier which forms the primary low-pass filter through a noninversion type integrator and a resistance. CONSTITUTION:The output signal of the primary low-pass filter 2 is fed back to the inverted input terminal of the operational amplifier 4 through the noninversion type integrator 3 and resistance 21. Namely, the output signal is fed back to the inverted input terminal of the amplifier 4 without being shifted in phase. Thus, the biquad type secondary band-pass active filter is formed and then the noninversion integrator 3 functions as a conventional amplifier and an inversion type integrator, so the same functions that a conventional filter has are obtained. Further, operational amplifiers are reduced in number to two, so the size and power consumption of the filter are reduced.

Title: Impeller of centrifugal compressor
Inventor: NOJIMA NOBUYUKI
IPC: F01D5/14
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To increase work applied on flow and reduce loss of flow by forming the inlet end rim of the blade of a curve line element formed in a concave surface in a rotational direction, and set a length between the curve line element and the straight line element to the length having a specified times of straight line element in the vicinity of the flow passage center. SOLUTION: An impeller consists of a cover disk 1, a blade 2, a hub disk 3, and the like. The inlet end of the blade 2 of the impeller is formed of a curve line element 4 formed in a concave surface in the rotational direction of the impeller. A distance S between the curve line element 4 and a straight line element 4a is gradually changed from the impeller inlet toward an outlet, it is formed in a flat shape in the impeller outlet. The distance S is set to 0.05 to 0.65 times of the length L of the straight line element 4a in the central part of a flow passage. It is thus possible to increase work applied on flow of the blade 2 in the central part of the flow passage, and it is also possible to reduce loss of flow per flow rate as the whole of the impeller so as to improve efficiency of the impeller.

Title: Method for directly assigning memory access priority in packeted data communication interface equipment and dma channel circuit
Inventor: BAKER RICHARD T
IPC: H04L12/64
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To perform the arbitration and scheduling of the DMA channels by shifting the execution of a DMA engine to the DMA channel having the highest priority when occurrence of a boundary condition is decided. SOLUTION: The information on the DMA channel number related to the transfer of data under operation is supplied to a DMA arbitration logic 72 via a physical medium interface that controls the connection between a personal computer and a peripheral device while the highest priority is assigned to the DMA channel number. The supply of the said information is carried on until the boundary condition that previously decided the service to the DMA channel under operation is confirmed. Then the execution of a DMA engine 74 is shifted to the DMA channel having the highest priority when occurrence of the boundary condition is decided. Thus, the arbitration and scheduling of the DMA channels are carried out.

Filed: 1985-05-24
Abstract: PURPOSE:To reduce a moire phenomenon by forming a total reflection surface totally reflecting incident light to project the reflected light to the observation side on each prism constituting a prism group and satisfying the relation between the pitch of scanning lines and that of the prism group with a specific condition. CONSTITUTION:The prism group is constituted of many prisms 1 arrayed so as to be expanded straight or like a circular arc and each prism 1 consists of the total reflection surface 1A totally reflecting incident light to project the reflected light to the observation side and an opposite surface 1B corresponding to its incident surface. Since the totally reflected light is projected through a part of a transmission part 1C on the observation side, no light is transmitted through a non-transmission part 1D and said state is repeated in each pitch of the prisms. When the pitch of scanning lines of a projecting television is set up to '1', the pitch of the prism group on a screen is set up to the range of N+0.35-0.45, N+0.55-0.65, 1/N+0.35-0.45, or 1/N+0.55-0.65.

IPC: D04G5/00
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To provide a suture cartridge assembly for surgical knots to facilitate the formation and arrangement of non-slippery surgical knots. SOLUTION: This suture cartridge assembly has a surgical knot partially tied (incomplete state) comprising a suture to facilitate the suturing of a tissue of a living being. The assembly also has a core tube 43 to which the partially tied knot, is connected, and moreover, has a suture cartridge provided with a tube slot 49 receiving the core tube 43. The assembly converts the partially tied knot to a non-slippery knot to facilitate thoroughly suturing the tissue in safety. The structure is so simple to make this assembly compatible with various surgical apparatuses.  By the conversion of the first partially tied knot to a completely tied knot, the complete knot and the core tube 43 involved can be removed to allow loading of the second partially tied knot connected to the perimeter of a new core tube 43 into the suture cartridge, thereby enabling the formation and arrangement of a plurality of knots.

Abstract: PURPOSE:To prevent the reverse insertion of a cassette size detecting plate and accurately distinguish the size of a sheet of paper by forming a bent part for preventing reverse insertion on the end edge part on the side on which a detecting part is not formed of the cassette size detecting plate. CONSTITUTION:In order to install a detecting plate 332 on a cassette case 354, with a detecting part 332a downside, inserting parts 332c, 332d on both ends are inserted into an inserting groove 354d and the plate 332 is strongly pressed. Thereby, the detecting part 332a is lowered until it is brought into contact with a groove bottom part 354f and positioned. Since the back of the base part 332b of the inserted detecting plate 332 is attracted to rubber magnet tapes 359 due to magnetism while being closely attached to and pressed against them by elasticity, the detecting plate 332 can be securely held without falling at the time of installing/removing a paper feeding cassette 30. Even if the detecting plate 332 is about to be reversely inserted with the detecting part 332a upward by mistake, a reverse insertion preventing bent part 332e hinders and the plate 332 is unable to be inserted into the inserting groove 354d, thereby, preventing the detecting plate to be reversely inserted in error.
