Title: Manufacture of magnetic head slider
Inventor: KOYAMA TETSUO
IPC: G11B5/60
Filed: 1995-01-27
Abstract: PURPOSE: To attain a uniform processing when chamfering is performed by moving plural sliders in the directions of X, Y while pressing to a grinding tape on a cushion material. CONSTITUTION: When the sliders 4a-4n are pressed to the cushion material 6 through the grinding tape 3, and the cushion material 6 is elastically deformed, and rail edges 1a-1c are processed, all sliders 4a-4n simultaneously processed are chamfered uniformly by prescribing grinding tape rigidity for effectively inserting the cushion material into an adjacent floating rail gap d2 being a minute gap. Thus, since the processing amounts of the rail edge inside 1b and the outside 1a are uniformized, an ideal chamfered state is obtained even in a block state before the slider 4 is separated into single bodies and the manufacturing method is suitable for mass-production.

Title: Wave dissipation building block
Inventor: AKAGI MASANORI
IPC: E02B3/14
Filed: 1979-02-05
Abstract: PURPOSE: To produce a wave dissipation block excellent in the wave dissipation effect with a simple construction for building a wave dissipation structure in revetments, quay-walls or the like with a concrete block having column-shaped members integrally connected being double crossed.  
     CONSTITUTION: Column-shaped combining members 3 and 4 of this wave dissipation block are arranged on column-shaped members 1 and 2 each leaving a distance of 1/4 from the end thereof. When the wave dissipation blocks are laid one upon another in a zigzag manner, the space between the column-shaped combining member 1 of one block and the column-shaped member 2 of another (the length between two spaces 13) becomes so constant that the wave dissipation rate can be constant wherever it stands. The combination of the convex part 6 and the concave part 5 prevents the deviation from the positioning at piling due to the force of wave. The groove 7 is provided to allow a trapping plate 8 to swing properly preventing wave from directly hitting the revetment or the like. With such an arrangement, the wave enters from front spaces 11 and 11 with a throttle mechanism when surging against a pile of blocks and then, is dispersed horizontally and vertically for dissipation.

Title: Interference compensation circuit between cross polarized waves
Inventor: WATANABE KAZUJI
IPC: H04J11/00
Filed: 1988-01-22
Abstract: PURPOSE:To make a system applicable even when a main signal and an interference signal differ by using a 3rd frequency conversion circuit so as to apply frequency shift in a way of maintaining the relation between the leaked frequency of an interference signal component onto a main signal and the frequency of the main signal before and after frequency conversion and detecting the interference signal by the same carrier as that of the main signal. CONSTITUTION:Let the oscillated frequencies of 1st and 2nd local oscillators be respectively fVL, fHL and the oscillated frequency of a 3rd local oscillator be (fVL-fHL), then the frequency of the interference signal outputted from the 3rd frequency conversion circuit 43 is higher than the intermediate frequency of the main signal by (fVL-fHL). The frequency (fVL-fHL) is coincident with a difference (fV-fH) between the frequency of the main signal and the frequency of the interference signal. Thus, the difference between the intermediate frequency of the main signal obtained from the 1st frequency conversion circuit 4 and the frequency of the interference signal obtained from the 3rd frequency conversion circuit 43 is the difference from the frequencies of the main signal and the interference signal. Thus, sufficient interference compensation is realized.

Abstract: PURPOSE: To achieve the improvement in image sharpness and gradation characteristic by applying low-frequency alternating voltages having the specified amplitude in the spacing between a latent image holder and a developer carrier.  
     CONSTITUTION: A latent image holder 11 and a developer carrier 12 are held and opposed by having a spacing in a developing part. When this spacing is let d micron, the low-frequency alternating voltages of VPP volt in the region of 1.5d≤ VPP≤1.5d+1500 are applied between the back electrode of the latent image holder 11 and developer carrier 12 at the developing. In this way, the amplitude of the external alternating voltages may be determined to an adequate value corresponding to latent image potentials under the specified development gap, and therefore there is no photographic fog and the sensible images superior in the reproducibility of line images may be obtained. Owing to the low-frequency alternating electric field application, the transfer of the developer to the non-image part and the reverse transfer to the developer carrier 11 are surely repeated in the spacing between the developer carrier 11 of the developing section and the non-image, whereby the development of superior gradation characteristic is obtained.
