Title: Magnetic head and magnetic recorder
Inventor: TANI KOUJI
IPC: G11B21/21
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head having small static friction force by forming a slider in such a manner that its floating surfaces or sliding contact surfaces have a texture of a honeycomb shape consisting of recessed parts of the shape that a polygonal shape or the corner parts of the polygonal shape have desired curvature. SOLUTION: Read-write elements 15 are mounted at the slider of the magnetic head. The texture of a honeycomb structure consisting of the recessed parts 8 and projecting parts 7 is formed on the sliding surfaces 6. The left side is the inflow side of the magnetic head and the right side is the outflow side. The honeycomb structure signifies the structure nested with the recessed parts. The preferable texture is such that the recessed parts 8 are preferably triangular to octagonal as the polygonal shape. The texture of such honeycomb structure is capable of storing the lubricant applied on the surface of the magnetic recording medium in these recessed parts 8 and, therefore, the lubricating film thickness of the front parts of the projecting parts in the progressing direction of the magnetic head is increased and the lubricant is more easily supplied to the projecting parts 7.  The wear of the projecting parts 7 of the texture is thus prevented.

Title: Defense communication method and its system
Inventor: ERI YANOFUSUKII
IPC: H04L9/16
Filed: 1995-02-14
Abstract: PURPOSE: To eliminate the move of key or the necessity of master key by transmitting a message between two units enciphered by a dynamic random key. CONSTITUTION: When two parties are initialized, between both the parties, cryptographic communication is enabled by the dynamic random key. The key is internally changed equally between two parties, both any key move and any master key is not required. The dynamic random key utilizes random bits remarkably less than the number of bits in a segment. These less random bits can take comparatively less redundant bits. As a result, the load of channel is minimized. Thus, quick communication is enabled. Further, the insertion of redundant bits is effective not only for confirming and correcting random bits but also for speedily confirming loss in synchronism between both the units.

Besides, the image data of the object image picked up again after prescribed time elapses is read out by the read-out circuit 35 and stored in the RAM 36 as the second image data. By comparing the first image data and the second image data stored in the RAM 36, the camera shake is detected. Then, display showing the occurrence of the camera shake is executed at a liquid crystal display part 7a so that the camera shake is informed and warned to a photographer.

Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To easily provide a circuit structure having high responsiveness to protecting operation in the life end of a discharge lamp at a low cost by controlling the operation of an oscillation control switch for discharging the charge of a starting capacitor by a lamp abnormality detecting circuit. SOLUTION: When the lamp voltage rises in the life end of a discharge lamp FL, and the voltage of a capacitor C7 rises and reaches the Zener voltage of a constant voltage diode DZ2, an oscillation control switch 4 is ON. The charge charged up in a starting capacitor C4 is then discharged, a main transistor Q1 is OFF to stop the oscillation, and the discharge lamp FL is extinguished. This state is continued by the current holding function of the transistors Q2, Q3 with thyristor structure of the oscillation control switch 4. Even when the discharge lamp FL is abnormally lighted in the life end, the discharge lamp FL is extinguished after a short time of about 3 seconds by setting the time constant of a lamp abnormality detecting circuit 5, so that the abnormal heating of parts can be prevented, and a user can be made to notice the lamp replacement.

Title: Method and device for controlling supply of original liquid to filtration chamber in filter plate type filter
Inventor: ITO KYOJI
IPC: B01D25/12
Filed: 1989-02-04
Abstract: PURPOSE:To uniformize the pressures in respective filtration chambers and to prevent the deformation and breakage of the filter plate by adjusting the branch openings of the respective filtration chambers in the filtration chambers held at different pressures due to the supply pressure of an original liq. CONSTITUTION:Many filter plates 1 are arranged and pressed with or without a filter frame in between. The original liq. is forced into a series of the original liq. supply ports formed by the feed material K of the filter plate 1 from one end side, and filtered. The original liq. is generally supplied to the filtration chambers E and F from the branch openings S of a series of original liq. supply passages, and filtered. In this case, since the filtration conditions of the adjacent filtration chambers E and F are different from each other, the branch opening S to the filtration chamber E, the internal pressure of which is increased due to the supply pressure of the original liq., is narrowed or closed to reduce or stop the supply of the original liq., and an increase in the internal pressure is prevented. Meanwhile, the branch opening S to the other filtration chamber F pressed by the filtration chamber E is expanded to impart an original liq. supply pressure, hence the internal pressure is increased, and the pressures of the filtration chambers are balanced.
