Abstract: PURPOSE: To change the rate of return flow gas before and after warming up operation of the device to improve the operating condition of an engine by fitting a working valve which opens at the temperature above the set temperature in a negative pressure passage connected to an exhaust gas return flow device.  
     CONSTITUTION: Suction and exhaust passages 2, 3 of an engine 1 are connected by an EGR passage 6 having an EGR valve 7. A negative pressure chamber 8 of the valve 7 is connected with a suction pipe 2 at right above a throttle valve 5 when it is completely closed through a negative pressure passage 9 which is constituted by a passage 9a which has a damper valve 14 with a delay mechanism and a passage 9b with a temperature sensing valve 15. When the temperature of the engine is below the set temperature, the temperature sensing valve 15 is closed and the  negative pressure is conveyed through the passage 9a, but, when it is above the set  temperature, the valve 15 is opened to convey negative pressure through both  passages 9a, 9b.

Title: Flame sensing device
Inventor: TAKECHI HIROSHI
IPC: F23N5/12
Filed: 1986-04-14
Abstract: PURPOSE:To provide a flame sensing device capable of sensing a flame even under a low voltage by a method wherein DC voltage is alternatively applied between a burner and an electrode to detect a waveform of an electric current. CONSTITUTION:In case that a flame is present in a burner 25 and Vi is Vcc, an electric current is flowed from an electrode 26 to a burner 25, a voltage drop is generated at a resistor 27, V- becomes a voltage lower that Vcc by an amount of VFR. In case that Vi is at GND level, V- becomes GND level. If a voltage of V+ is set to a value between Vcc and (Vcc-VFR), an output Vo of an operation amplifier 30 becomes High only when a flame is present at a burner 25. In case that a flame is not present and the burner 25 and the electrode 26 are short circuited to each other, Vo becomes a High-Low output which is synchronous with Vi to enable a flame to be detected. In this case, when a flame is present and an output of the operation amplifier 23 is High, an electric current is flowed in the resistor 27 and a voltage drop is generated, so even if Vcc is low, a stable output can be attained. With the foregoing arrangement, a low DC voltage is alternatively applied between the burner 25 and the electrode 26, thereby a flame can be detected.

Title: Prevention of uneven spin coating and spin coater
Inventor: TADA YOSHIAKI
IPC: H01L21/30
Filed: 1985-04-22
Abstract: PURPOSE:To reduce any uneven coating due to bubbles remarkably, forming coated films with excellent evenness, by a method wherein coating agent is dripped on the position distant from the rotary center of coated material. CONSTITUTION:The center B of nozzle 4 is arranged on the position distant by e from the rotary center A of a coated material 1. When coating agent 5 is dripped from a deflectively located nozzle 4, the dripped coating agent 5 is spread almost circularly on the position deflected from the rotary center A of coated material 1. The dripped amount of coating agent 5 shall be specified to get over the rotary center A toward the opposite side. When a spindle 3 is rotated, bubbles 6 are externally blown away rapidly together with the coating agent 5 disappearing from the coated material 1 since the bubbles 6 being distant from the rotary center A, the coating agent 5 around the bubbles 6 is subject to relatively intensive centrifugal force. Through these procedures, any uneven coating due to explosion of bubbles 6 can be reduced remarkably.

Title: Destuff control circuit
Inventor: YAMASHITA MIKIO
IPC: H04J3/07
Filed: 1991-04-18
Abstract: PURPOSE:To configurate the control circuit with low speed devices and to reduce power consumption by applying serial parallel conversion to an input signal so as to decrease the operating speed, generating a destuff pulse in the lock system at a slow operating speed and restoring the speed to the speed of the input signal. CONSTITUTION:A serial parallel conversion circuit 2 expands an input signal 1 whose word consists of n-bits being an asynchronizing signal in the unit of words in parallel by n-sets to decrease the signal speed to 1/n. A stuff decision circuit 3 decides the presence of destuff of the received signal from the circuit 2 based on the majority decision of bits in the stuff control in the clock system of a fundamental frequency or the like, and a pulse generating circuit 4 is controlled by the circuit 3 to generate a pulse with 1 word width when the destuff is in existence. A speed conversion circuit 5 restores the output with frequency system clock accuracy of the original signal 1, a differentiating circuit 6 differentiates and shapes the output to output a destuff pulse 7 of one bit width. Thus, even when the data transmission speed is fast and the circuits 3, 4 make complicated processing, the circuits are made up of low speed devices.
