Title: Sealed-type lead-acid battery
Inventor: YOSHINO HARUMI
IPC: H01M50/528
Filed: 1991-05-27
Abstract: PURPOSE:To suppress proceeding of corrosion caused by an electrolyte existing in a joint part between a polar column and a battery terminal by connecting the joint part between the polar column and the battery terminal to a solder containing silver. CONSTITUTION:A battery is composed of a plate group consisting of a positive plate, a negative plate, and a separator and a casing for accommodating the plate group and the joint part between a polar column 1, which is a part of the negative plate, and a battery terminal 2 is sealed by an adhesive 3. In this case, in order to make silver exist in the joint part between the polar column 1 and the terminal 2, the polar column 1 and the terminal 2 are joined together by a solder containing 0.05-2.0wt.% silver. Since the joint part becomes in the state that the potential of the negative plate is applied thereto by making silver exist in the joint part between the polar column 1 and the terminal 2, an effect that silver prevents segregation of tin to the solder 4a surface is obtained. Consequently, since the concentration, on the surface of solder 4a, of oxides which are easily corroded by sulfuric acid can be lowered, the corrosion owing to the electrolyte staying in the interface between the joint part and the adhesive can be prevented from proceeding.

Title: Method for recognizing change on screen
Inventor: CHIYOU SEIYOKU
IPC: G06F3/05
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To discriminate and recognize quickly a change in a screen without the need for a memory of a large capacity by dividing one screen image consisting of video signals of one frame or one field into a prescribed number of unit screens to compare characteristic values denoted on each unit screen. SOLUTION: In the case of dividing one screen into many unit screens, the screen is divided so that each unit screen is not overlapped and unit screens are gathered to form the entire one screen. In the case that one screen consists of m×n set of picture elements, when one screen is divided into m1 ×n1 sets of unit screens, the unit screens each having picture element numbers of (m/m1 )×(n/n1 ) are produced. A change on the screen is discriminated by comparing characteristic values of each unit screen, since a data amount stored and compared is reduced, discrimination is conducted quickly while reducing the memory capacity.

Title: Device and method for compressing and restoration of binary image
Inventor: CHIN TAMIAKI
IPC: H04N1/411
Filed: 1995-05-19
Abstract: PURPOSE: To provide a binary image compression/restoration device which can secure high compressibility by converting a binary input image including a pseudo halftone into a multilevel image and then compressing this multilevel image. CONSTITUTION: A device 1 of the compression side converts the binary image to be sent to a device 4 of the restoration side into a multilevel image through a binary/multilevel estimation part 2. Thus the quantity of data on the multilevel image is larger than the binary image by 8 times. A coding part 3 codes the multilevel information that is outputted from the part 2. The compressibility of the multilevel image is increased by 8 times or more in an international standard JPEG system. As a result, the quantity of information that is increased by 8 times through the part 2 is reduced down to 1.0 time or less compared with the original binary image. In other words, true overall compressibility is equal to 1.0 time or more. The compressed multilevel image is sent to the device 4 via a transmission line 7.  A decoding part 6 applies the entropy decoding, the inverse quantization and the inverse DCT conversion to the compressed multilevel image and outputs a decoded image.

Abstract: PURPOSE:To reduce the unevenness of rotation by changing the clock frequency in a digital servo, in a phase where a torque ripple is generated. CONSTITUTION:A driving circuit for a brushless motor 19 is composed if a magnetoresistance element 11 and its FG amplifier 20, an oscillator 13, a frequency divider 14, a counter 15, a D/A converter 16, a compensating filter 17 and a driver 18, and changes a supply current to the motor 19. In this case, a corrective circuit 21 and an A/D converter 26 are also provided and said corrective circuit 21 produces a torque ripple cancel correction signal by a three phase back electromotive force waveform. The output of said corrective circuit 21 is converted into a digital value by said A/D converter 26. Then, where a generated torque is lower than a desired value, the latch output of said counter 15 is latched at a large value and a high voltage is applied to the motor 19 so that a current value increases and the generated torque becomes higher. On the contrary, where said generated torque is higher than said desired value, a service voltage drops and the generated torque lowers too.

Filed: 1991-05-27
Abstract: PURPOSE:To preserve a long-term effective data in a memory device of small capacity by preserving every specific number of running data as one group every time it is collected and preserving the average value of the adjacent two data in the previous data as a representative value. CONSTITUTION:When a first period 2<n> X time has passed after the collection of the running data was started, 2<n> data is collected in a data collecting device and preserved as a group G1 in a secondary memory device. Then, when a second period 2<n> X time has passed, another 2 data is collected in the memory device and preserved as a fresh group G1. The average value of the adjacent two time series data in the previously stored group G1 is preserved as a group G2. In this manner, the number of data in the group G2 is reduced to 2<(n-1)>. If this sequence is repeated, a long-term effective data can be preserved in a memory device of small capacity.

CONSTITUTION:The sunlight available in the morning is focused on the first heat-collecting member 2 through the linear lens 1 to heat the member 2 to a high temperature of about 200 deg.C. Therefore, the first heat pipe 3 also starts to operate at about 200 deg.C, thereby heating a heat- transmitting medium flowing in the first heat-transmitting medium pipe 6. A controlling circuit 13 is operated by a signal from a temperature detector 12, whereby pumps P1, P2 intermediately provided in circulating passages 9a, 9b are operated, and solenoid change-over valves 10, 11 are so changed over as to communicate the passage 9a to a high-temperature heat-accumulating tank 8H. On the other hand, the second heat-collecting member 4 receives only the diffused light, so that it is heated only to about 40 deg.C, and a heat-transmitting medium of a low temperature is accumulated in a low-temperature heat-accumulating tank 8L. When the sun moves to its afternoon position, the system is changed over to a condition reverse to that during the morning by the temperature detector 12. In addition, a thermoelectromotive force corresponding to the temperature difference of 160 deg.C between the heat pipes 3, 5 is taken out by the thermoelectric converting element 15 through leads.

Title: Ferroelectric material and ferroelectric memory using the same
Inventor: MIURA KAORU
IPC: H01B3/12
Filed: 1995-05-19
Abstract: PURPOSE: To obtain a ferroelectric material which is useful as a ferroelectric memory with suppressed fatigue and an stabilized characteristic by doping a lead, titanium and zirconium oxide (PZT oxide) with a rare earth element except lanthanum. CONSTITUTION: This ferroelectric material is prepared by doping a PZT oxide with one or plural rare-earth elements except lanthanum. The use of this ferroelectric material as a ferroelectric layer in the capacitor gives a ferroeletric memory. As for this ferro-electric material and the ferroelectric memory, the doping of the PZT oxide with rare earth elements except lanthanum allows the electrons remaining when an oxygen atom splits off not to go in the 3d band of titanium atom but to in the 4f band of a rare earth atom whereby the fatigue caused by the electron coming in the 3d band of titanium can be inhibited or avoided. Thus, a ferroelectric material with increased stability and prolonged life can be produced and the material can be used as a ferroelectric layer in the capacitor to give a ferroelectric memory of stabilized workability and device characteristics.
