Title: Rotary type variable resistor
Inventor: SASAKI SEIYA
IPC: H01C10/32
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To miniaturize a rotary type variable resistor and to prolong the life of the resistor by a method, wherein the resistor is constituted into such a structure that in a change-over of sliding members between the first contact parts of first electrodes and the second contact parts of second electrodes, the sliding members are changed over in a state that the adjacent first and second contact parts are made to have continuity with each other. SOLUTION: When an axis of rotation is rotated, sliding members are rotated, contacts S1 and S2 are respectively contacted with first, and second contact parts 3b and 4b and are separated from the contact parts 3b and 4b to change over the sliding members from the contact parts 3b to the contact parts 4b and from the contact parts 4b to the contact parts 3b. Together with that, a contact S3 makes contact slidingly with a drawing-out part 6 at all times to change the resistance values between terminal parts 5 and the part 6 in a stepwide manner.  Moreover, when the sliding members are changed over from the contact parts 3b to the contact parts 4b or from the contact parts 4b to the contact parts 3b, the adjacent contact parts 3b and 4b are put in a state that they are overlapped each other so that each one end of the contact parts 3b, and each one end of the contact parts 4b are overlapped each other in a radial direction H.

Title: Frequency synthesizer
Inventor: IWAMOTO MASAKI
IPC: H03L7/187
Filed: 1993-01-28
Abstract: PURPOSE:To reduce the frequency switching time and to exclude adverse effect due to a temperature change by changing forcibly an input voltage to a voltage controlled oscillator(VCO) with a preset voltage at frequency switching. CONSTITUTION:When new frequency data are inputted to a control section 10, the control section 10 sets a frequency division ratio to a variable frequency divider 6 and reads the temperature at that time from a temperature sensor 11. A preset voltage is read from a table stored in a RAM 8 based on voltage information for the correction by the temperature and new frequency data and the voltage is inputted to an adder 7 via a D/A converter 9. Then the adder 7 adds the preset voltage to a voltage from a loop filter 4 to forcibly change the input voltage to the VCO 5. Thus, an output signal of a desired frequency is momentarily selected without reception of the effect of a time constant of an RC circuit of the loop filter 4.

Title: Method for dividing motion estimate area
Inventor: MATSUMOTO SHUICHI
IPC: H04N19/15
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide the method for dividing a motion estimate area for a moving image that improve the coding efficiency or the motion compensation predictive efficiency. SOLUTION: An image is divided into N-sets (N is a positive integer) of small blocks Bj(j=1, 2,..., N). The small block is formed to be, e.g. 4×2 picture elements, which is a minimum unit of the area division (Figure a). Then as to all the small blocks Bj, a value of a standard (SAD) of a degree of matching for compensation prediction such as motion compensation prediction error absolute sum or square sum of all object motion vectors vi(i=1, 2,..., L) is calculated (Figure b), and an SAD table being a table of a standard of a matching degree in the entire image is generated (Figure c). Then the SAD table is used to extract significant candidate moving vectors v'i(i=1, 2,..., M, where M<=L) (Figure d). Then, the small blocks are integrated to be an area for uniform motion parts by using the significant candidate moving vectors v'i(i=1, 2,..., M).  The integrated area provides object shape information.

Title: Production of large-sized lightweight foamed concrete panel
Inventor: SUDO SHINGO
IPC: C04B32/02
Filed: 1994-03-03
Abstract: PURPOSE:To prevent cracking during steam curing at and under a high tap. and high pressure by adding gypsum dihydrate to a slurry so as to contain a specific rate of calcium sulfate with respect to a total solid content, thereby producing a large-sized lightweight concrete panel. CONSTITUTION:The gypsum dihydrate is added to the slurry mixture composed of a siliceous raw material, cement, calcareous raw material contg. slaked lime and/or quicklime as main raw materials and water in such a manner that the slurry contains the calcium sulfate at an internal ratio of 1 to 5wt.% of the total solid content in the process for producing the large-sized lightweight concrete panel by casting the slurry into a form arranged with reinforcing bars, curing the slurry to solidify half and subjecting the slurry to the steam curing at and under the high temp. and high pressure. Acicular ettringite crystals are formed by a hydration reaction of the cement and calcium sulfate which are the calcareous material in the half solidified and cured body. The expansion by the deficiency of the ettringite in the half solidified and cured body is suppressed and the cracking is caused if the amt. of the ettringite to be formed is below 6wt.%. The crag by decomposition and shrinkage arising from the increased formation of the ettringite arises in the half solidified and cured body when the at. exceeds 10wt.%.

Title: Speed change control device for automatic transmission
Inventor: NISHIO MOTOHARU
IPC: F16H61/06
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To give compensation so as not to excessively enlarge the working pressure of an friction element even if the operation characteristic of an actuator changes by correcting a predetermined command value and a working hydraulic pressure characteristic so that the working hydraulic pressure of the joint side friction element becomes higher than the same command value from a controller to the actuator. SOLUTION: During down shifting under the power on running, corresponding to transmission input torque at starting inertia phase, dislocation of a map is generated so that the commanded hydraulic pressure of a joint side friction element (forward clutch F/C) is lower than the actually generated hydraulic pressure, and hence the operation characteristic map of a joint side actuator is corrected, so that the commanded hydraulic pressure Pc of the joint side friction element (forward clutch F/C) becomes higher than the same command value to a solenoid 9. Hereby, even if the operation characteristic of the joint side actuator generates dispersion or changes, there is no possibility that the working pressure Pc of the joint side friction element becomes excessively high, and expected gear shift quality can be attained always surely.
