Title: Control method for voltage type vvvf inverter for driving de electric vehicle
Inventor: NUMANO TOSHIO
IPC: B60L9/18
Filed: 1990-11-29
Abstract: PURPOSE:To protect an axle or the surface of rail against damage, to realize stabilized control and to improve readhesion characteristics by limiting the inverter frequency within a moderate range upon occurrence of idling or slip even on a single axle. CONSTITUTION:Upon occurrence of idling at time t1, input current id1 to a unit inverter 301 in an inverter unit 31 decreases from id0 to id0 corresponding substantially to zero level. Consequently, differential current ic1 between the currents id0 and id0' flows into an input capacitor 302 thus increasing the voltage across the capacitor 302. When the voltage rise is detected at time t10' output current from a sound inverter (32, on the drawing), which is not idling, is decreased thus decreasing the inverter input current from id0 to id0'. At a time tZ when idling phenomenon disappears, outputs from all inverters are increased simultaneously thus returning the input current from id0' to id0.

Title: Globe rotary type input device
Inventor: YONEMITSU SHINOBU
IPC: G06F3/0354
Filed: 1987-12-23
Abstract: PURPOSE:To ensure the satisfactory operability with a globe rotary type input device regardless of the scale of the information on the rotation value by setting previously plural types of functional relations between the physical rotation value and the information on the rotation value received from a joint part and selecting the prescribed one of those functions for instruction. CONSTITUTION:When a globe rotates, a control part 3 recognizes the physical rotation value based on the outputs of a vertical rotation value measuring part 1 and a horizontal rotation value measuring part 2. Then the part 3 applies the function arithmetic to the physical rotation value based on the functional relation designated by the states of switches 7 and 8 and sends the information on the rotation value to a joint part 4. The part 4 sends the received information to terminals 5 and 6. The switches 9 and 10 have nothing to do with the information on the rotation value. Thus the states of both switches 9 and 10 are recognized by the part 3 and sent to both terminals 5 and 6 as they are via the part 4. Thus the satisfactory operability is ensured with a globe rotary type input device regardless of the scale of the information on the rotation value.

Title: Method of forming electrode bump for connection
Inventor: KOBAYASHI TSUNEO
IPC: H01L21/60
Filed: 1988-12-26
Abstract: PURPOSE:To form an electrode bump in one process by a method wherein melted conductive metal is spouted out onto a substrate while the substrate is rotated and the melted conductive metals is made to adhere to foundation metal only. CONSTITUTION:After a rotary chuck 2 is rotated, a pressure pump in a pressure chamber 6 is driven and solid solder particles 7 are spouted out toward a substrate 1 from a nozzle 3. The spouted solid solid particles 7 fall on the surface of the substrate 1. As the substrate 1 is rotated and the particles do not have wettability and reactivity with the substrate 1, the solid solder particles 7b falling directly on the substrate 1 are scattered away from the center of rotation by a centrifugal force and finally discharged out of the substrate 1. On the other hand, the solid solder particles 7a falling on foundation metal 8 are made to stay on the foundation metal 8 by wettability and reactivity with the foundation metal 8 and an electrode bump is formed on the surface of the foundation metal 8. With this constitution, an electrode bump for connection can be formed in one process without using a masking member.

Title: Method for changing rolling thickness of running hot rolled strip
Inventor: KIKUCHI HIROYASU
IPC: B21B45/02
Filed: 1992-11-11
Abstract: PURPOSE:To secure an amount of cooling water between rolling stands which can obtain a desired target finishing temperature even though plate thickness and finishing temperature are changed drastically.

Title: Manufacture of grating in waveguide
Inventor: FARRIES MARK
IPC: G02B6/134
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To overcome the complexity of a process for forming gratings within waveguides subjected to ion diffusion by irradiating at least either of waveguide regions with light and generating permanent refractive index changes within the plural quantities among the waveguide regions, thereby forming the gratings. SOLUTION: The waveguide regions are formed within the waveguide regions within a circumferential substrate and where the waveguide regions are covered with the circumferential substrate in the ion exchange process. The photosensitive ions are diffused into the substrate by the ion exchange process to give rise to the refractive index difference from the adjacent non-diffusion regions of the substrate. At least any of the waveguide regions is irradiated with the light with suitable intensity and duration time, by which the permanent refractive index changes are generated within the plural regions among the waveguide regions and the gratings are formed. The permanent refractive index changes of the Bragg grating form are thus generated within the substrate formed with the ion-diffused waveguides therein.

Filed: 1994-12-28
Abstract: PURPOSE: To prevent a current from being leaked and to reduce power consumption by providing a holding means to hold a gap between the light source and a condensing means to be constant between the light source and the condensing means. CONSTITUTION: By a silver reflection sheet 104, the light of a cold cathod fluorescent lamp 101 is condensed to a light transmission body 103. By the transmission body 103, the whole of a liquid crystal display element is irradiated with the light emitted from the lamp 101. The lamp 101 is interposed and held by a rubber bush 102 through the elasticity thereof.

Title: Combustion device
Inventor: MOGI KUNITOYO
IPC: F23G5/00
Filed: 1990-11-27
Abstract: PURPOSE:To enable execution of complete combustion without needing a combustion assisting means by a method wherein one side of the ceiling surface of a combustion chamber forms a feed port for incinerating substance, the opposite side forms an exhaust port, and a combustion promoting plate is suspended from a ceiling surface in the middle. CONSTITUTION:A combustion chamber 1 has a charge port 4 for an incinerating substance formed in the one side of a ceiling part and an exhaust port 5 formed in the other side of the ceiling surface. A combustion promoting plate 6 made of a metal is suspended from a ceiling surface in the middle between the exhaust port 5 and the charge port 4 and a given distance (l) is provided between the combustion promoting plate and a floor surface 7. An incinerating substance is charged in a primary combustion chamber 1a and the upper part thereof is ignited. Air is fed and regulated through a gap between the charge port 4 and a cover body 2. A combustion air flow flows through the distance to a secondary combustion chamber 1b. Since, in this way, combustion is progressed from the upper surface of the incinerating substance to below, the generation of smoke is extremely reduced even at the initial stage of ignition. Further, since the interior of the secondary combustion chamber 1b is maintained at a high temperature through the catalyst action of the promoting plate 6, a combustion flow is completely burnt. Besides, during above process, other combustion assisting means is eliminated, and an initial and a running cost can be reduced.
