Title: Leak measuring instrument
Inventor: MATSUMURA SHIZUO
IPC: G01M3/04
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matter from being bitten between the sliding surfaces of a cylinder and a piston, and prevent the operation failure by sticking of the piston by providing annular recessed groves in stepped parts formed in the front and rear of the piston, and fitting sealants to the grooves to seal the sliding surfaces of the cylinder and the piston. SOLUTION: A piston 3 is slidably fitted into a cylinder 1, and pressure chambers A, B are formed of the cylinder 1, a piston 3, and a lid body 2 screwed to the end of the cylinder 1. When the pressure chamber A is pressurized, and a hydraulic equipment connected to the chamber B has no leak, the pressures of the chambers A, B are equal to each other, so that the piston 3 is not moved. When the hydraulic equipment to be measured is leaked, the pressure of the chamber B is lower than that of the chamber A, and the piston is slid on the chamber B side within the cylinder 1.  Even if a chip or foreign matter is included in the chambers A, B and about to be nipped between sliding surfaces (h), the foreign matter is eliminated by dust seals 7a, 7b, the piston 3 is moved without sticking, and it is detected by a stroke sensor 6 according to the moving quantity to measure the leak of the equipment.

Title: Two-dimensional method and system for compressing binary image
Inventor: SHIYAN CHII
IPC: H04N1/411
Filed: 1995-09-19
Abstract: PURPOSE: To compress a binary bit map image to a variable length mode code and a variable length counting code. CONSTITUTION: A raster line is read from a binary bit map image and the read raster line (present column) is comapred 40 with the raster line (reference column) just before. When the byte within the present column is equal 41 with the corresponding byte within the reference column, the byte is expressed in a copy mode 42 in the compression column. The copy mode means that the byte should be copied from the reference column to the present column. When the byte of the present column is not equal with the byte of the reference column, the next byte within the present column is read 43, and the byte and the previous byte are compared. When the byte is equal with the previous byte, the byte is expressed in a repeat mode 40 in the compression column. When the byte is not equal with the previous byte, the byte is expressed in a literal mode 46 in the compression column.

Title: Speed control device for motor
Inventor: YAMASHITA KOJIRO
IPC: H02P6/08
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To control the speed of a motor over a wide range, by using boosting chopper circuit to control the speed in a high-speed range and a power conversion device to control pulse-width modulation in a low-speed range. SOLUTION: When the speed of a brushless direct-current motor is controlled, use of a boosting chopper circuit as means of varying direct-current voltage Ed prevents a boosting chopper from being actuated and makes it incapable of controlling supply current 10 to sine waves in proximity to the crest value of a supply voltage 21, when the direct-current voltage Ed is to be reduced below the crest value of the supply voltage 21. In order to cope with this, in a range where the direct-current voltage Ed exceeds the crest value of the supply voltage 21 a boosting chopper circuit 3 is used to exercise direct-current voltage control, and high-speed control mode in which PWM control is not exercised is established in an inverter 4.  In the order ranges, such a control for making the direct-current voltage Ed constant is exercised in the boosting chopper circuit 3, and low-speed control mode in which PWM control is exercised is established in the inverter 4. As a result, speed control becomes possible over a wide range.

Filed: 1987-09-28
Abstract: PURPOSE:To keep temperature rise of each module at a relatively uniform value and to keep a temperature of each LSI device at a uniform value by connecting a cooling water pipe to each module in parallel. CONSTITUTION:Modules form four lines; water of the upper two lines thereof is supplied and drained from a cooling water inlet tube 3 and an outlet tube 4 provided above.

Title: Structure with seismic control function
Inventor: KOBORI TAKUJI
IPC: E04H9/02
Filed: 1993-09-28
Abstract: PURPOSE:To effectively reduce a seismic response to the wide range extending from a weak or strong earthquake to a disastrous or ruinous earthquake, by a method wherein an active type seismic control apparatus is provided on the upper of a structural frame and passive type seismic control apparatus each are located at the lower floors of the structural frame. CONSTITUTION:An active type seismic control apparatus 2 with dynamic vibration reducers is provided on the upper part of a structural frame 1 and an passive type seismic control apparatus 3 with elasto-plastic dampers is located at each of the lower floors thereof. When a weak or strong earthquake below a very strong earthquake occurs, the apparatus 2 displays the effect of controlling the movement of the structural frame 1 and reduces a seismic response. When a very strong disastrous earthquake occurs, some of the elasto-plastic dampers in the apparatus 3 yield, absorb vibrational energy, and reduce the responce. Under such conditions, furthermore, the apparatus 2 displays the effect and reduce the response more and more. When a disastrous or ruinous earthquake occurs, the rest of the elasto-plastic dampers in the apparatus 3 all yield, absorb the vibrational energy, and reduce the response. In this case, the apparatus 2 is also actuated and reduces the response.

Title: Cartridge storage case and its production
Inventor: IKEBE MASARU
IPC: B65D85/57
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To provide a cartridge storage case and its production method for taking out an index card easily and for easy handling. SOLUTION: A holding part which holds a minidisk M inserted between a main body 30 and a cover member 20 rotating integrally in opening the cover member 20 is formed. When the cover member 20 is opened, the minidisk M stored in the storage case 10 also ratatory moves. Therefore, even if an index card ID is placed between the minidisk M and the main body 30, the index card ID can be taken out without pulling out the minidisk M. Also when the cover member 20 is closed, the bottom end of the holding part goes into the inner recess of the main body and the top end of the same protrudes from the inner face of the main body 30. Thus the index card can be held between the bottom end of the cartridge holding part and the inner recess of the main body making it possible to surely hold the index card.

Abstract: PURPOSE:To keep an operating voltage low and to improve optical coupling efficiency by providing a switch part having high refractive index only to the surface of an optical waveguide and providing optical fiber coupling parts having a symmetrical refractive index distribution to both sides thereof. CONSTITUTION:The optical waveguide 5 is formed of the optical switch part 6 and the optical fiber coupling parts 7 on both sides thereof. Mg is first diffused in an LiNbO3 substrate to form the optical switch part 6 at the time of forming such waveguide. Ti is then diffused to the part of the substrate 1 corresponding to the waveguide pattern passing the optical switch part 6 to form the optical waveguide 5. Mg is diffused in both ends thereof to form the optical fiber coupling parts 7. Since the switch part 6 has the high refractive index only on the surface, the operating voltage is kept low. The optical fiber coupling parts 7 have the symmetrical refractive index distributions and can, therefore, improve the coupling efficiency to optical fibers.
