IPC: F24F11/02
Filed: 1986-03-12
Abstract: PURPOSE:To effect defrosting after deciding whether actual heating capacity exists or not surely by a method wherein defrosting operation is controlled by a set boundary temperature storing means and the time of operation in accordance with electric source frequency and the amount of airflow in a room while the value of set temperature difference is changed in accordance with the amount of airflow in the room. CONSTITUTION:The frequency of the port P1 of the output side of a microcomputer is decided by a 50-60Hz deciding means in the microcomputer 9 through a signal from a 50-60Hz clock generating circuit and when it is 60Hz, the output of the port P1 is made Hi, a reference voltage, generated by the divided voltage of a resistor 15, is elevated, the values of resistance of resistors 16, 17, 18 (value of resistance 16<17<18) connected to respective terminals are changed by an airflow amount switching switch and heating operation is started by changing a set pipeline temperature (t3) by the amount of airflow (strong, middle and weak) in accordance with the value of resistance to secure the heating operation for a predetermined period of time T (1hr for example) by the micrcomputer 9. When the period of time T has elapsed, pipeline temperature (t1) is read by a pipeline temperature detecting element 6 and a heat exchanger temperature (t2) is read by a heat exchanger temperature detecting element 6'. A comparator 12 decides whether the difference between the temperatures (t1) (t2) is smaller than a set temperature (t) and defrosting operation is started.

Abstract: PROBLEM TO BE SOLVED: To provide the digital filter which speedily adapts itself to a case wherein a distortion component superposed on an input signal has large nonlinearity and which generates a stable output signal. SOLUTION: This filter is equipped with three partial computing elements P1 to P3 which filter an input signal x(n) and its delayed signals x(n-1) and x(n-2) and which add processed signals s1 to s3 generated by the partial computing elements P1 to P3 to generate an output signal (y). The partial computing elements Pi (i=1 to 3) find error cumulative values epi (merely called an error) from error signals ei between the processed signals si and a target signal. If an error exceeds a permissible value at one partial computing element the target signal of the partial computing element Pa having the least error at this time is set to a training signal (d) representing an expected output.  In other cases, the target signal of a partial computing element having an Nth small error is set to the error signal of a partial computing element having an (N-1)th small error so that the errors of the partial computing elements Pa are compensated.

Title: Digital information transmission system
Inventor: SHIKAKURA AKISUKE
IPC: H04N19/00
Filed: 1988-03-09
Abstract: PURPOSE:To more efficiently transmit digital information with a small circuit by using a chain encoding error correcting code where the direction of correlations used for compression encoding at the time of transmission and the direction of an error correcting code finally decoded at the time of decoding on the reception side coincide with each other. CONSTITUTION:A preceding value forecasting DPCM circuit 32 converts the digital picture information signal of an input terminal 30 to a DPCM data string. The direction of correlations used for compression is the horizontal scanning direction. A double encoded error correcting code is added to this DPCM data by an outer code encoding circuit 34 and an inner code encoding circuit 36. The outer code is equalized to the direction of correlations used for information compression. The signal received from a transmission line is demodulated by a demodulating circuit 42, and an inner code decoding circuit 42 and an outer code decoding circuit 44 decode the inner code and the outer code respectively in accordance with a prescribed algorithm to correct errors. A correction flag indicating that correction is impossible is written in a correction flag memory 46 with respect to the code whose correction is judged to be impossible at the time of decoding the outer code. An error correcting circuit 50 uses the correction flag to correct the data string where there is error left.

Filed: 1992-03-13
Abstract: PURPOSE:To evade inconvenience owing to the erroneous operation of a switch by taking out the operating signal of the switch only when the switch is operated again within a prescribed period after the push button switch is operated. CONSTITUTION:When a timer 14A completes the clocking of time T1, the timer is started by the succeeding relation of the output signal of the timer 14A and the timer 14B starts the clocking of setting time T2 When the push button switch 20 is operated again at the point of time t3 during the clocking of time T2, the output signal of an edge detecting circuit 12 based on the re-operation is outputted from an AND circuit 17. Thus, a flip-flop is set at the point of time t3. When the operated push button switch is turned off at the point of time t5, a resetting circuit which detects the succeeding relation of an inverter output resets the flip-flop 18. In result, the flip-flop 18 outputs a logical level L from the point of time t3 for the re-operation of the push button switch to the point of time t5 for re-operation completion.

Title: Cooling mechanism for heating component
Inventor: CHIYOSHIMA TOSHIO
IPC: H01L23/36
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To realize uniform thermal conductivity and improvement in cooling efficiency, by using a thermal conduction component made of a shape memory metal memorizing a shape corresponding to a predetermined temperature as a heat medium between a heating component and a radiation component. SOLUTION: Shape memory metals, for example, of rectangular-columnar shape, may be changed in height by causing the cross section to change from a rhombic shape to a square at a predetermined modification temperature so that the angle made by each side becomes a right angle. Such shape memory metals are connected in parallel to form a flat plate. A thermal conduction component 1 made of the shape memory metal memorizing a shape corresponding to a predetermined temperature is used as a heat medium between a heating component 2 and a radiation component 3, so as to conduct the heat of the heating component 2 to the radiation component 3.  By this means, a change in height of the thermal conduction component 1 of the shape memory metal along with a rise in temperature increases the contact stress between the heating component 2 and the radiation component 3, and elastic deformation increases the contact area. Thus, the thermal resistance between the heating component and the radiation component is reduced, thereby enabling efficient thermal conduction.
