Title: Sleeper
Inventor: ONISHI KUNIAKI
IPC: E01B3/00
Filed: 1994-09-30
Abstract: PURPOSE:To prevent the lateral dislocation of a track caused by lateral shifting force applied at the rail passing time and facilitate the return of a sleeper by providing a sleeper body with protrusions or recessed grooves of specific shape. CONSTITUTION:The ballast laying face of a sleeper body 1 is provided with protrusions 2 or recessed grooves. At this time, the longitudinal section area of the protrusion 2 or the recessed groove is formed to be gradually smaller toward one side in the longitudinal direction of the sleeper body l. For instance, the height h1 of one end face of the protrusion 2 in the longitudinal direction of the sleeper body l is made 5mm or more and three-quarters or less of the height h2 of the other end face, or the width of one end part of the protrusion 2 in the longitudinal direction of the sleeper body 1 is made one-fifth to three- quarters of the width of the other end part. The major axis direction dislocation of the sleeper body 1 is prevented by making the protrusions 2 bite into the ballast or making the ballast enter into the recessed grooves.

Title: Core device
Inventor: NISHIYAMA TAKAYOSHI
IPC: H01F27/24
Filed: 1996-09-06
Abstract: PROBLEM TO BE SOLVED: To maintain a constant contact area between a first core and legs of a second core, even if the positions of the legs are shifted, by exposing the surface of the first core in a direction where the positions of the legs are shifted when the legs of the second core are overlaid on the surface of the first core. SOLUTION: An I-shaped core 12 has a size larger than that of a connection portion 10. Legs 11A and 11B are overlaid on the surface of the core 12. When a U-shaped core 9 is placed at the center of the I-shaped core 12, the surface of the I-shaped core 12 is exposed around the legs 11A and 11B. When an adhesive tape is rolled around, even if the positions of the U-shaped core 9 and the I-shaped core 12 are shifted, the area where the legs 11A and 11B are in contact with the surface of the I-shaped core 12 is maintained constant. This prevents change of inductance of a coil or a transformer.

Title: Picture processing unit
Inventor: OUCHI YASUSHI
IPC: H04N1/40
Filed: 1990-09-05
Abstract: PURPOSE:To obtain a binary data resulting from eliminating a picture from an original in mixture of character, graph and picture data at a high speed by detecting a circumscribed rectangular area of a picture data area and clearing the inside of the circumscribed rectangular area after the reading of the original (filling in white level data). CONSTITUTION:When an image sensor 1 reads an original in mixture of character, graph and picture data, its analog input signal is converted into a digital signal by an A/D converter 3. The digital signal is inputted to 1st, 2nd, 3rd comparators 5, 7, 9, in which the signal is compared with a white and a black threshold level and the data is discriminated into a black picture element/white picture element data. Then the picture data is inputted to a picture data circumscribed rectangular area detection circuit 22, in which an outermost point of the picture data is detected to detect the circumscribed rectangular area of the picture data area. Moreover, the picture data in the detected circumscribed rectangular area is cleared into a white level by a clear circuit 26. Thus, only a character and graph part resulting from eliminating the circumscribed rectangular area of the picture data from the original in mixture of character, graph and picture data is extracted as a binary data at a high speed.

IPC: G01V1/18
Filed: 1994-09-30
Abstract: PURPOSE: To obtain an optical seismograph in which the maximum vibratory speed value is measured accurately by an optical means upon occurrence of an earthquake. CONSTITUTION: The optical seismograph comprises a slip plate 5 which is displaced to the right and left by a quake, and a light emitting element 8a and a light receiving element 8b arranged on the opposite sides of the slit plate 5. A counter circuit 11 determines a maximum vibratory speed value directly from an intermittent pulse signal being detected per a predetermined time by the light receiving element 8b when the slit plate 5 is displaced by a quake to pass the light intermittently through a slit 5a. The maximum vibratory speed value thus determined is presented on a display 12. When the maximum vibratory speed value is higher than a set value, a stop signal is delivered to the process thus interrupting the process emergently.

Title: Signal receiver
Inventor: HOSHINO TAKEHIKO
IPC: H04L27/148
Filed: 1983-12-15
Abstract: PURPOSE:To allow detection of the signal wave independently by the one-type filter by providing a circuit which multiplies the frequency by compressing only the time base without changing the original waveform by the multiplication degree in correspondence to the signal frequency to be detected, and by selecting the output frequency signal from the circuit by the filter for the receiving signal. CONSTITUTION:In a frequency multiplication circuit 4, the multiplication degree is set so that the frequency after multiplication will fit a selection central frequency fo of a carrier filter 5 provided at the rear step for a signal frequency fc to be detected. For example, when the signal frequency fc to be detected is set as (n) of fc1-fcn, multiplication degrees N1-Nn are set so that the following equations will estabilish: fc1XN1=fo, fc2XN2=fo, and ...fcnXNn=fo. Therefore, only the small-size carrier filter 5, which is the one type of the slection central frequency fo, is provided for (n) signal frequency fcl-fcn, and the receiver can be minimized remarkably.

Title: Window system, computer system, and window display method
Inventor: IWAMURA ETSUJI
IPC: G06F3/048
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To maintain display contents which were displayed before the size of a window is changed even after the change by managing the display contents with vector data. SOLUTION: An external position specifying process part 12 divides the whole screen including all windows into several parts and manages them. When there are the windows in sections corersponding to the divided and managed parts, the depression of a button of a position specifying device 4 which correspond to the section is detected when the button is pressed, and an indication is sent to a screen display management part 13 so that the window screen linked with the button is enlarged and displayed. When a window screen whose display is managed with a vector is varied in size, a management part 13 acquires the varied size. On the basis of the acquired result, the size of display vector data stored in a vector data storage part 14 is varied by a vector conversion part 16. Consequently, while the display contents of the window screen are held, the size of the window is varied.
