Title: Amplitude limiting amplifying circuit
Inventor: KAWAKAMI HIROMI
IPC: H03D1/22
Filed: 1981-11-17
Abstract: PURPOSE:To improve phase modulation, and to obtain a satisfactory amplitude limiting output signal, by differentially connecting the first and the second transistors (TR), and also the third and the fourth TRs, and connecting the collectors of the first and the fourth TRs to an electric power supply. CONSTITUTION:TRs 27a and 27b, and TRs 28a and 28b are differentially connected, respectively. Subsequently, when an input sgnal from an input signal  source 36 is supplied to each base of the TRs 27a, 28b, an output signal whose  amplitude has been limited to a value decided by a current value of constant- current sources 30, 31 is obtained in output terminals 32, 33. In this case, the  constant- voltage circuit is in low impedance, and also the collectors of the TRs  27a, 28b are connected to an electric power supply terminal 29 without passing through a substantial impedance, therefore, the collector-base mirror capacity of  the TRs 27a, 28b is reduced, and the collector-base feedback is not executed.  Accordingly, it is possible to improve phase modulation generated due to such  mirror capacity of an output signal of an amplitude limiting amplifying circuit 7,  and a satisfactory amplitude limiting output signal is obtained.

Title: Input and output port
Inventor: BAN AKIRA
IPC: G06F13/12
Filed: 1985-08-21
Abstract: PURPOSE:To reduce the through current flowing to a bus driver by using a clock signal generating circuit which delivers the clock signal to a latch circuit when the input/output changeover signal shows an input mode and also both the address and write signals are supplied. CONSTITUTION:The output of a 3-input AND gate 3 is set at a high level when both the address signal A and the write signal W are set at high levels respectively. While the output of a 2-input OR gate 1 is set at a high level and the data on a bus is stored in a latch circuit 5 via a transfer gate 4. Then the data stored in the circuit 5 is delivered to an input/output terminal 7 via an output buffer 6. In an input mode the input/output changeover signal C is set at a high level together with the output of an inverter 11 set at a low level respectively. Therefore both the buffer 6 and the gate 4 are turned off with an input buffer 8 turned on respectively. Thus the through current is prevented from flowing to a bus driver.

Title: Gas supply device
Inventor: YAMAZAKI TAKASHI
IPC: B60S5/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To eliminate oil component and water content in the gas. SOLUTION: This gas supply device 31 is provided with an oil trap 32 for recovering oil components to be contained in the compressed gas. The oil trap 32 is comprised of a drain line 33 branched off from a gas supply line 24 to be situated at the downstream side of a control valve 28, and a nut-shaped plug 34 screwed in an end part of the drain line 33. Gas whose flow rate is throttled by the control valve 28 is discharged out of the control valve 28 whereby it is expanded and its temperature goes down, and oily steam and water content evaporated in the gas are condensed into drops of dew on a line inner wall of the gas supply line 24.  Accordingly, both oil and water drops condensed on the line inner wall of the gas supply line 24 being more downstream than the control valve 28 flows into the drain line 33 installed at the more lower position than the gas supply line 24, and thus they are gradually gathered in a trailing line 33b. With this, in gas charging, such a possibility that any oil component and water content might be supplied to a filling container 23 at the automobile side can be prevented from occurring.

Title: Failure diagnostic device for evaporative fuel processing device
Inventor: OKUMA SHIGEO
IPC: F02D45/00
Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous diagnosis of failure (leak) diagnosis of an evaporative fuel processing device. SOLUTION: After an ignition switch is put on in operation by an operator, and if diagnostic condition including prestart condition that an engine is in its stopped condition is established (step 100-step 101), initialization is executed (step 102-step 103). After that, presence of leak is diagnosed (step 104-step 112) by making a comparison between a driving current value when air pressurized and supplied by an electric pump is exhausted through a reference orifice and a driving current value when pressurized air is supplied to the inside of an evaporative fuel processing device. Therefore influence such as vibration in the fuel tank caused by engine operation and internal pressure rise of the device caused by exothermic action from the engine can be avoided and erroneous diagnosis can be prevented.
