Title: Identification circuit
Inventor: KINOSHITA TAIZO
IPC: H04B10/69
Filed: 1987-12-25
Abstract: PURPOSE:To absorb a DC reproduction error due to the fluctuation in the mark rate or same code consecution by adopting the circuit constitution such that only a peak after DC recovery is not detected from a signal subjected to DC fluctuation in an identification circuit but a true amplitude is always detected and its median is given as a threshold level. CONSTITUTION:A peak value detection circuit 7 and a threshold level control circuit 8 are provided. At first a signal after DC recovery is given to a maximum value detection circuit 7 and a minimum value detection circuit 71. After the maximum and minimum value are detected in each circuit, the amplitude is detected by calculating the difference. Then the median of the amplitude is formed from the amplitude by a control circuit 80 and given as a threshold level of an identification circuit 3. Since both the maximum and minimum values are fluctuated in the same direction even when a DC level of an input signal is fluctuated in addition to the fluctuation of the amplitude of the input signal, the threshold level is fluctuated by the same level and the level is always set to 1/2 of the input amplitude. Thus, the amplitude information is always detected against the fluctuation in the mark rate or same code consecution.

IPC: F02M25/07
Filed: 1987-12-25
Abstract: PURPOSE:To make accurate trouble diagnosis possible by opening/closing an EGR valve at the time of the decelerating operation of an engine, measuring the change of an intake amount which is generated at the time of opening/closing, and judging the presence of the trouble of an EGR device by the measured result. CONSTITUTION:During the running of a vehicle, when a throttle valve 10 is closed and an idle switch 12 is made to be ON while the engine speed which can be calculated from the power of a crank angle sensor 19 is reduced, the engine is judged to be in the decelerating operational state in an ECU 4 so that a trouble diagnostic circuit is made to start. Then, when a specified period passes in the decelerating operational state, an intake amount V1 at the time when an EGR valve 3 is fully closed is measured by an air flow sensor 6 and memoried. Next, the EGR valve 3 is fully opened for a specified period, and an intake amount V2 after a specified period is measured. Difference between said measured flow amounts is calculated and compared with judging value. When difference between the measured flow amounts is below the judge value, the EGR valve 3 is judged to be in the state of trouble so that an alarm lamp is lighted.

IPC: C08G18/64
Filed: 1991-11-15
Abstract: PURPOSE:To obtain a starch foam excellent in biodegradability by heating a starchy material in the presence of an acid catalyst and a polyhydric alcohol, and foaming and hardening the obtained liquid material. CONSTITUTION:A starchy material is heated at 30-200 deg.C in the presence of an acid catalyst and a polyhydric alcohol (polyol) to liquefy the material. The obtained liquid material is then foamed and hardened to give an objective foam. As the starchy material serving as the starting raw material, a wide variety of common starches such as corn starch, potato starch, tapioca starch and wheat starch are used. Modified starches obtained therefrom are also used; an esterified or etherified starch preferably having a degree of substitution of 0.01 to 0.5 is used while other cross-linked starches can also be used. This foam has wide application; for example, it can realize even the foaming while bonding to wood or paper to thereby give a product generally having high peel strength.
