Filed: 1979-06-27
Abstract: PURPOSE: To prevent the deposition of adherent matters and improved heat exchange, by providing inclined porous plates in a high-temperature and a low-temperature gas ducts and supplying spherical heat accumulating pieces.  
     CONSTITUTION: High-temperature gas is introduced in a direction 10 and passes through a high-temperature gas side porous plate 4 to fluidize spherical heat accumulating pieces on the plate 4 to produce a fluidized layer 8. After that, the high-temperature gas flows out in a direction 11. The high-temperature gas gives heat to the spherical heat accumulating pieces which constitute the fluidized layer 8. Therfore, the high-temperature gas is cooled. The heat accumulating pieces heated by the gas are supplid to a low-temperature gas side through the opening of a partition wall 3. Low-temperature gas is introduced in a direction 12 and passes through between the heat accumulating pieces of a moving layer 9 which is constituted by the pieces fed from the high-temperature gas side. After that, the low- temperature gas flows out in a direction 13 through a low-temperature gas side porous plate 5. The low-temperature gas absorbs heat from the heat accumulating pieces. The heat accumulating pieces cooled by the low-temperature gas flow out in a direction 15 through an outlet port 17 but are returned to an inlet port 6 by a separate means.

Filed: 1988-03-31
Abstract: PURPOSE:To decide the quality of plural memory cells by outputting one bit among plural bits in addition to the bit to show the coincidence/non-coincidence of plural bits, and deciding by using those bits. CONSTITUTION:The inverse of CAS is let fall following the fall of the inverse of RAS, and the inverse of WE is let fall, and data is written in a DRAM 1.

Title: Breaker for wiring provided with leakage alarm function
Inventor: SAKATA MINORU
IPC: H02H3/34
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To transmit the break of leakage to a remote monitor without fail, when performing the opening breaking action and the alarm output action at the same time by equipping a breaker with a leakage relay, which outputs a leakage alarm to an external device by a ground fault occurrence signal, and a delay circuit which opens an opening contact after passage of a specified delay time.

By setting the time when a leakage relay 8 can operate the delay time of a delay circuit 16 in advance, the control current of the leakage relay 8 from an AC electric path by the opening of an opening/closing contact 2 is does not become lost, and the leakage relay 8 can transmit the signal of the leakage break without fail via an alarm connector terminal 9.  Moreover, the ground fault occurrence signal is not supplied at the same time to the thyristor 17 and a leakage relay driving thyristor 19, so that the output imposition of the ground fault detecting circuit 5 can be lightened.

Title: Photomask for semiconductor integrated circuit
IPC: G03F1/70
Filed: 1992-04-02
Abstract: PURPOSE:To shorten the time required for reticule formation and to enable inexpensive manufacture by partially cutting off a part of the patterns of the size smaller than the resolution threshold of an exposing device arranged on a glass substrate in compliance with the patterns of semiconductor integrated circuits. CONSTITUTION:The chromium patterns 2 of the size which cannot be resolved by the exposing device are regularly disposed similarly at the intervals which cannot be resolved on the glass substrate 1. These microchromium patterns 2 are formed by cutting off the microchromium patterns 2 in the unnecessary parts according to pattern data from the chromium patterns formed over the entire surface on the glass substrate 1. Light hardly passes the parts where the microchromium patterns 2 array regularly on the reticule and is not exposed on the semiconductor substrate. The regions where there is no chromium above the resolution threshold are made in the sections where the microchromium patterns 2 are cut off. The exposing light passes these regions and a photoresist is exposed on the semiconductor substrate, by which the patterns are formed.

Abstract: PURPOSE:To improve a vertical resolution characteristic by providing a means for relatively processing a signal outputted through an outline signal forming means and a signal without said means so as to have an substantially equal interval in terms of a centroid of sensitivity by an interlace driving. CONSTITUTION:An adder 54 adds outputs of an outline process circuit 52 and an interlace correcting circuit 53 and outputs the adding signal to a luminance signal process circuit not shown in figure. In this manner, when a vertical correlation is not present from an input luminance signal Yin to an output signal forming circuit 51, the vertical outline signal is formed, and its output is processed in the circuit 52 in one end, in the other end, interpolated and corrected in the circuit 53 together with the signal Yin. These signals are added in the adder 54 to obtain an output signal Yout. Thereby, a dislocation of the centroid of sensitivity by the interlace driving of the image sensor is corrected and a vertical resolution characteristic is improved.
