Patent JP-S556163-A (JP)
Title: Combustion detector
Inventor: HARIMA KATSUNORI
IPC: F23N5/12
Filed: 1978-06-28
Abstract: PURPOSE:To delay ignition for a time after misfire through a very simple construction, by providing a flame detection delay circuit wherein two resistors and a capacitor are connected in series with a flame rod. CONSTITUTION:The resistors 11, 12, the capacitor 13 and the flame rod 14 are connected in series with an AC power source 10, thereby forming the flame detection delay circuit. In misfire, the capacitor 13 is discharged through a resistor 16. When the voltage of the capacitor 13 is reduced below a divided voltage determined  by the combined resistance of resistors 19, 20, 21 and a diode 22, the misfire signal  of a voltage comarator 23 disappears. As a result, a transistor 26 is turned off, a  relay 27 is deenergized, a relay contact 8 is closed and an ignition transformer 7 is  energized again for ignition. The ignition is delayed for the time from the misfire to the re-energization of the transformer via the discharge of the capacitor 13.

Title: Refrigerant distributor
Inventor: AOKI AKIRA
IPC: F25B41/00
Filed: 1989-03-29
Abstract: PURPOSE:To make the distribution of refrigerant approach evenness for improving and increase the heat exchange amount by a method wherein a delivery pipe is allocated for each group of two or more branch pipes to be connected to the delivery pipe, and a partition plate is provided in a distribution main pipe for each group of the branch pipes. CONSTITUTION:The refrigerant R flowing from an inlet pipe 4 is firstly divided into two streams RH and RL by branch pipes 3H and 3L, and the divided streams are separated from each other by a partition plate 6 which divides a distribution main pipe into two sections 2H and 2L, and then flow into outlet pipe groups 5H and 5L. The distance from the branch pipes 3H and 3L to the farthest outlet pipes is shortened by one half as the distribution main pipe is divided into two, thereby the number of outlet pipes for each of the branch pipes 3H and 3L is reduced by one half. Therefore, the unevenness of flow due to the action of gravity is reduced by the gas-liquid mixed flow of the refrigerant R. As a result, the refrigerant flowing through two or more outlet pipes 5 is approx. evenly distributed to refrigerant pipes of a heat exchanger, so that the heat exchange amount of the heat exchanger is improved and increased.

Title: Analog/digital converter
Inventor: ISHIZAKA KUNIMASA
IPC: H03M3/00
Filed: 1990-03-29
Abstract: PURPOSE:To attain A/D conversion with accuracy over bit accuracy of an A/D converter in use by presetting an initial digital value corresponding to a level of a synchronizing signal to a storage circuit when the synchronizing signal appears in an input analog signal and applying A/D conversion to a level of a difference signal for each clock period succeedingly and adding the result. CONSTITUTION:When a synchronizing signal appears in an input analog signal, an initial digital value corresponding to a level of the synchronizing signal is preset to a storage circuit 18, and a level of a difference signal for each clock period obtained from a differential amplifier circuit 13 is converted into a digital value at an A/D converter circuit 16. Then the value is added to the initial digital value by an adder circuit 17, the sum is stored into the storage circuit 18, from which the value subject to A/D conversion is outputted. Thus, the A/D converter circuit 16 does not need to convert the analog signal of the maximum amplitude into a digital value and is enough to be a circuit applying A/D conversion to a level of a difference signal for each clock period. Thus, a digital signal in a bit number over a bit number of the A/D converter circuit in use is outputted and the accuracy is improved.

Title: Adsorbent made of carbon fiber and production thereof
Inventor: MAEDA TAKESHI
IPC: B01D53/02
Filed: 1989-03-29
Abstract: PURPOSE:To efficiently produce an adsorbent having superior ability to adsorb a polar gas of low density at a low cost by regulating the specific surface area of carbon fibers to 30-700m<2>/g and the oxygen content to >=3wt.% by treatment at 250-900 deg.C in the presence of oxygen. CONSTITUTION:Unactivated carbon fibers made from polyacrylonitrile, rayon, cellulose, phenol resin, pitch, etc., are heat-treated in the presence of oxygen to form oxygen-contg. groups such as carbonyl or carboxyl groups on the carbon fibers. At this time, the heat treatment is carried out at 250-900 deg.C, an oxidation reaction is allowed to proceed smoothly and the oxygen content is regulated to >=3wt.%. The specific surface area is increased to 30-700m<2>/g but the radius of pores is kept small because activation proceeds by oxidation. An adsorbent having superior ability to adsorb a polar gas of low density such as ammonia is effectively produced at a low cost.
