Title: Address conversion device
Inventor: ISHIDA AKIHIKO
IPC: G06F12/10
Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To improve inexpensively a hit rate of a virtual address and conversion speed of an address. SOLUTION: When a virtual address does not exist in a first address conversion buffer 21 but exists in a second conversion buffer 23, a control mechanism 24 sends a third control signal to the second address conversion buffer 23. In response to this, the second address conversion buffer 23 transmits a real address corresponding to the virtual address to a physical memory 25. Moreover, the second address conversion buffer 23 registers a pair of addresses regarding the hit virtual address with the first address conversion buffer 21. Since a new pair of addresses are registered with the first address conversion buffer 21 which operates at high speed, the hit rate is improved in the first address conversion buffer 21 in the address conversion from the next time onward and a time needed for the address conversion can be shortened.  In addition, it is unnecessary to access to a conversion table 251 and it is possible to suppress a time needed for the address conversion.

Title: Probability distribution generation system and optimization system applying the same generation system
Inventor: KAMIBAYASHI TATSU
IPC: G06F19/00
Filed: 1992-01-14
Abstract: PURPOSE:To generate a probability variable accordant with an optional distribution at a high speed by securing the approximate continuation of plural probability processes per unit time where a state shift means shifts the state of a state storing means to a prescribed state in regard of plural units which contain the state storing means and the state shifts means respectively. CONSTITUTION:This system comprises 2<q> pieces of units (spins) 200 that contain a state storing means 210 which stores the system state, a state shift means 220 which updates the system state, and a storage means 230 which stores a calculation procedure and a constant respectively. These units 200 are connected to each other in the form of a binary tree. In the Markov processes which are continuous in terms of time in a state space of a system of spins, the minute time is applied to the shift rule of each spin and the probability processes are approximately continuous. Thus the Markov process is simulated. Thus it is possible to shift the spins in parallel to each other. Then the system state is converged into a probability variable having a given distribution.

Title: Method for brazing different kind of materials
Inventor: NAYAMA RISUKE
IPC: B23K35/00
Filed: 1987-01-13
Abstract: PURPOSE:To prevent brazing materials from penetracting into a cushioning material by applying materials mixing ceramix powder with a solvent to the porous cushioning material inserted between both materials as a wetting preventive for the brazing materials. CONSTITUTION:The materials 2 mixing the ceramic powder with the solvent are applied to the metallic fiber surface in the neighborhood of the joint surfaces between a metallic fiber and the cushioning material 1 in order to prevent the brazing materials 3 from wetting. Furthermore, it is necessary to remove the wetting preventive on the contact surface between the cushioning material 1 and the brazing materials 3. As to the materials to be joined, for instance, stainless steel and graphite are used as the material 4 with the high coefficient of thermal expansion and the material 5 with the low coefficient of thermal expansion respectively. When said cushioning material 1 is inserted between the two kinds of materials to perform the brazing, it is prevented that the brazing materials 3 penetrate into the cushioning material 1 and a function of the cushioning material 1 can be maintained. Accordingly, a crack does not take place on the graphite and the materials with the different coefficient of thermal expansion can be joined.

Title: Manufacture of aluminum clad stainless steel
Inventor: KITAZAWA KOUJI
IPC: C23C2/40
Filed: 1979-01-20
Abstract: PURPOSE:To obtain an Al-clad stainless steel having a high workability and corrosion resistance in sulfur atomosphere by forming Al-coated layer with molten Al on austenitic stainless steel material at a specific temperature. CONSTITUTION:18-8 austenitic stainless steel plate 1 is degreased and cleaned in water wash tank 5, and is dried in dryer 6. The steel plate 1 is then preheated at preheater 7 consisting of flux bath to 690-750 deg.C, and is passed through molten Al tank 8 at about 700 deg.C to coat Al on the stainless steel plate 1. Al coating processed at this temperature prevents non-ductile Fe-Al alloy layer to form between the stainless steel and Al layer. This further prevents the mother material stainless steel to dissolve into Al layer. As a result, this process provides Al-clad austenitic stainless steel plate having a high workability and high resistance to S atmosphere such as H2S.

IPC: B41J2/485
Filed: 1986-01-14
Abstract: PURPOSE:To enable a script character pattern to be generated from a character of ordinary size by performing a logic sum operation on every mutually adjoining two of a plurality of bits of parallel output data from a character pattern memory and selecting either of a character pattern memory output and a logic sum circuit output. CONSTITUTION:A character pattern of ordinary size (e.g. 16 bits) is stored into a character pattern memory 1 and read by a memory read control circuit 2. Then the pattern is latched into a register 3. Parallel character pattern data b1-b16 from the register 3 are input to a logic sum circuit 4 by every two mutually adjoining bits (b1 and b2...b15 and b16). When script characters are generated, as a gate control signal C, a logic value '1' is output representing output data 01-08 as parallel output data of the logic sum circuit 4, and a logic value '0' representing output data O9-O16. When characters of ordinary size are output, the logic value '0' is set as the gate control signal C enabling parallel outputs b1-b16 of the register 3 to be output as they are as output data O1-O16.

Title: Brake control device for vehicle
Inventor: YUMOTO DAIJIRO
IPC: B60T8/174
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To sharply shorten the wasteful time until reaching the dead zone of a valve by offset-correcting a dead zone width before learning, and increasing a current instruction value. SOLUTION: This brake control device is provided with a before learning dead zone width calculating means calculating a before learning dead zone width from the differential pressure between the upstream and downstream sides of a hydraulic control solenoid valve, a dead zone width learning means for learning and storing the dead zone width of the hydraulic control solenoid valve based on the before learning dead zone width, a hydraulic control solenoid valve current instruction value and a brake oil pressure measured value, and a means offset-correcting the hydraulic control solenoid valve current instruction value.  When a brake oil pressure instruction value is decreased from a fixed value, for example, the before learning dead zone width is offset-corrected from the differential pressure between the W/CYL pressure and the atmospheric pressure, then a hydraulic feedback compensating unit functions, and a decompression valve current instruction value is increased. When it exceeds the valve dead zone, the brake oil pressure measured value exceeds the prescribed value, thus the decompression valve dead zone learning conditions are satisfied, and this decompression valve current instruction value is stored.

IPC: G02B23/24
Filed: 1988-01-14
Abstract: PURPOSE:To improve operability by selectively powering on a main shape memory alloy member to curve a curving part in a prescribed direction and a subordinate shape memory alloy to assist the main member and to increase a curving force quantity. CONSTITUTION:When a curving part 3 of an inserting part 2 is curved to an UP side, and a first SMA(shape memory alloy) coil 4 is powered on by an UP switch 9, the first SMA coil 4 is contracted, and the curving part 3 is curved in the UP direction. When the UP switch 9 is turned off, the first SMA coil 4 loses contraction force due to natural cooling, and the curving part 3 is returned to a straight condition due to the elasticity of the other SMA coil 4. When the curving force quantity in the UP direction is increased, and a force quantity UP switch 13 is simultaneously turned on together with the UP switch 9, the first, second, and twelfth SMA coils 4 are powered on and heated, and the curving force quantities for three coil portions can be generated. In such constitution, the large curving force quantity can be obtained as needed, and the operability can be improved.

Title: Incombustible honeycomb structural material and manufacture thereof
Inventor: HAYASHI KENZO
IPC: B32B19/02
Filed: 1994-01-25
Abstract: PURPOSE:To reduce physical distribution cost and storage space by a method wherein elastical folding to before-expansion state is made possible. CONSTITUTION:Honeycomb structural material main body 1 consists of incombustible sheet 2 mainly made of sepiolite. Next, on the whole surface of the main body 1, aqueous dispersion liquid prepared by dispersing water glass composition, which is gelatinized in advance and then crushed to particles, in water is applied by immersion treatment or the like and dried. Thus, inorganic covering 4 made of water glass composition is integrally formed so as to cover the surface of the honeycomb structural material main body 1 made of incombustible sheet 2 under the condition that the surface is covered not by continuous filmy skin but by minute particles. Since the honeycomb structural material equipped with the inorganic covering 4 has proper elasticity and flexibility, the structural material can be folded again to before-expansion state.

Inventor: FUKUDA HIROSHI
IPC: G03F1/50
Filed: 1994-01-25
Abstract: PURPOSE:To enhance resolution and depth of focus by providing a thin film having transmittinity dependent on the incident angle of light between a mask and an illumination optical system when the mask is irradiated with light from a light source through the illumination optical system and a pattern on the mask is projected onto a substrate through a projection lens. CONSTITUTION:When a mask 3 is irradiated with light from a light source 1 through an illumination optical system 2 and a pattern on the mask 3 is projected onto a substrate through a projection lens, an interference filter 13 for increasing the transmittinity relatively to the mask 3 is disposed between the mask 3 and the illumination optical system 2. The interference filter 13 has transmittinity dependent on the incident angle theta being set such that the transmittinity for vertical incident light is decreased. The angular drstribution of light illuminating the mask 3 is controlled variously and the spatial frequency transfer characteristics of the optical system are varied thus enhancing the resolution and increasing the depth of focus. This method allows formation at an LSI having circuit pattern dimensions of about 0.2-0.3mum.
