Title: Address conversion circuit
Inventor: TAKASE SHUNICHI
IPC: G06F12/08
Filed: 1988-05-26
Abstract: PURPOSE:To shorten the clear time of a RAM by constituting the effective bit part of address conversion data of a flip-flop resettable by one clock. CONSTITUTION:The FF(flip-flop)18 stores the effective bit of the address conversion data in an address conversion part. When an RS (reset signal) signal is inputted from the RS input terminal 19 via an input terminal 18e, the FF18 is reset for all words in spite of the value of the signal since precedence higher than that of the signals inputted from a clock input terminal 18a, a decode result input terminal 18b, a data input terminal 18c, and a write control input terminal 18d is attached on the RS signal. Since an effective bit signal So outputted from the FF18 to an output terminal 18f is nullified, an effective bit signal S3 outputted from a selection circuit 17 is also nullified, and also, the output signal of an AND circuit 16 and absolute address data outputted from an output terminal 11 are nullified.

Title: Wick
Inventor: TOMIZAWA TAKESHI
IPC: F23D3/08
Filed: 1981-08-19
Abstract: PURPOSE:To obtain a wick which is almost free from an influence of tar, by mainly composing the vaporizing part of a wick with heat-resistant fiber of below 2 microns in size. CONSTITUTION:The vaporizing part 3 of a wick is composed of fiber below about 2 microns in diameter. Kerosene is vaporized from the surface of a fuel vaporizing part 3. In case that kerosene, mixed with an oil of different quality, or degenerative kerosene is used, tar is accumulated on the surface of a vaporizing part 3, but most of tar is vaporized by thermal decomposition, as soon as it is accumulated on the surface. Because the vaporizing part 3 is made of porous material, unfavorable influence such that remarkable lowering of combustibility will scarcely occur in a combustor, even if some quantity of tar will remain on the surface. By composing the fuel vaporizing part with such a fiber, unfavorable influence by tar to a wick can largely be decreased.

When the deviation exceeds the preset value, a signal is issued, a value corresponding to the time constant is set in a counter 20, and a gate circuit G3 is opened. Then the value, which is obtained by amplifying the output of the subtracting circuit 18 by an amplifier circuit 21, and the held value of the holding circuit 16 are added in an adding circuit 22. Then the corrected relative humidity value is displayed on a display circuit 24. Thus, the highly accurate measured value of the relative humidity without temporal errors can be obtained.

Title: Pyroelectric infrared detector
Inventor: MASUDA NOBORU
IPC: G01J1/04
Filed: 1987-05-27
Abstract: PURPOSE:To securely detect a heat source by arranging a reflecting shield plate which reflects an infrared ray between a pyroelectric infrared sensor element and a Fresnel lens so that the space between a couple of elements is partitioned. CONSTITUTION:The reflecting shield plate 8 made of aluminum is provided almost in the middle between the 1st element 4 and 2nd element 5 of the sensor element 3. Then, when a heat source moves from a detection area (a) to a detection area (b), the heat source is in the detection area A of the element 4 itself, so the infrared ray enters the element 4, but no infrared ray enters the element 5. Consequently, there is a difference generated between the output levels of the elements 4 and 5 and a differential output E1 is obtained from the sensor element 3. Similarly, no differential output is obtained in heat-source movement sections bd and gh, a differential output 2E1 is obtained in movement sections de and ef, and a differential output E1 is obtained in a section hi. Thus, a detectable area is created newly at the overlap of the areas A and B by the reflecting shield plate 8 and more effective detection becomes possible.
