Title: Digital controller
Inventor: KANO IKUO
IPC: G05B11/26
Filed: 1990-04-28
Abstract: PURPOSE:To cope with even a high speed motor-operated valve by reading out the output with a 2nd clock signal of the 1/n arithmetic sampling cycle by estimating output obtained at each output timing when each arithmetic sampling cycle is computed. CONSTITUTION:A sampling cycle is divided by 1/n in each arithmetic cycle to estimate a specific number of pieces of ON signals that should be carried on before the next sampling cycle. Hereafter the ON signals are outputted based on the result of estimation in each 2nd cycle, i.e., each output cycle. Then the output signals are kept OFF until the next sampling cycle at an output cycle of the estimated number of ON signals. Thus the ON/OFF operations of the output are estimated n 1/n cycle shorter than the sampling cycle. Thus it is possible to a fact that the present value exceeds extremely the target value during a sampling cycle in a small hunting degree and with high accuracy.

IPC: H01M2/10
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To detect the abnormal heat generations of individual batteries and prevent the fusions of temperature fuses from being caused by a short circuit current. SOLUTION: In respective batteries B1-B8 stored in a battery pack 50, temperature fuses H1-H8 are provided respectively, and the temperature fuses H1-H8 are connected in series with each other. The temperature fuse H1 is connected with one terminal of a thermistor TM to connect the other terminal of the thermistor TM with a detecting terminal T7.

Title: Block selector of memory unit
Inventor: FUJII NORIKAZU
IPC: G06F12/06
Filed: 1979-09-06
Abstract: PURPOSE:To simplify a block selecting circuit while preventing malfunction by using a few address lines from the lowest-order and highest-order ones as memory- unit selection lines and block selection lines. CONSTITUTION:For addition by block selection switches in each memory unit, S2 is a one-bit adder, S3 is a two-bit adder and S4-S7 are three-bit adders. Blocks B1-B8 are selected by comparing circuits C1-C8. The number of address lines A is three and when those three lines are all held at ''0'', the selection state is set. As for four memory units, although memory blocks B1-B8 may be selected in parallel, only one unit is enabled by selecting circuits composed of SW1-SW7, S2-S7 and C2-C8 to operation and in or from one address information is written or read. The high-order three lines are used as block selection lines, the need for an address setting switch is eliminated and setting errors are also eliminated, so that the block selecting circuit can be simplified.

Title: Heat sensitive pressurizing device
Inventor: UTSUNOMIYA YUTAKA
IPC: B30B1/10
Filed: 1983-06-25
Abstract: PURPOSE:To reduce the usage of a shape storing alloy by energyzing a toggle joint with the aid of a shape storing spring. CONSTITUTION:When temperature reaches a level exceeding the transformation point, a shape storing spring 32 produces a elastic restoring force several times larger than that in the martensite phase, causing the force for pulling a toggle joint 20 closer to the stopping part 27 side to be increased. Namely, the toggle joint 20 is displaced in the direction of increasing an opening angle theta, and the theta approaches about 180 deg., so that it is possible to move a pressuring member 17 to the supporting part 8 side by increasing tensile force due to the shape storing spring 32 to several or several ten times even if said tensile force is small. Hereby, it is possible to obtain pressurizing force equivalent to the conventional one even with the reduced usage of a shape storing alloy material.

Title: Digital/analog conversion circuit
Inventor: SHIDA FUMIO
IPC: H03M1/80
Filed: 1988-05-11
Abstract: PURPOSE:To add optional offset voltage to analog output voltage through the use of a few element lines by combining a weighted resistor and a single grounded base transistor (TR). CONSTITUTION:An N-bits-quantized digital signal is inputted from digital input terminals 101-10N (N is integer), and weighted resistors 111-11N are determined in their resistance ratio according to the weight of an input signal. Because the emitter potential of the TR 130 can be considered to be at fixed potential independently of the magnitude of an emitter current as base potential is fixed, current values to flow in the resistor 111-11N having been weighted are inversely proportional to respective resistance values. By converting the collector current of this TR 130 into voltage by a load resistor 132 connected to a collector, a D/A converting operation is attained. Further, by varying the output potential of a variable voltage source 133 connected to the load resistor 132, the offset potential can be given to a D/A converted output signal.
