Title: Current source circuit
Inventor: OGAWA SHIGEO
IPC: G05F3/26
Filed: 1982-07-28
Abstract: PURPOSE:To realize high precision, stability, and small power consumption by obtaining a current whose value is determined by only the values of a resistance and a positive source voltage through single conversion from a current source circuit which has the positive power source and a negative power source. CONSTITUTION:The bases and collectors of diode-connected NPN and transistors (TR) Q6 and Q5 are connected in common respectively to constitute a current mirror circuit, so the collector currents of the TRs Q5 and Q6 are equal and currents flowing through NPNTRs Q1 and Q2 are also equal. Since the base of the TRQ1 is connected, V1=V2=0, where V2 is the base potential of the TRQ1 and V1 is the potential at the base (collector) point A of the TRQ2. Therefore, a standard current Iref is determined only by the values of the voltage VCC of the positive power source 1 and the resistance R. A required output current Iout is generated by the single conversion of the current mirror circuit of TRs Q7 and Q8, and its value depens on the emitter area ratio of the TRs Q7 and Q8, the voltage of the positive power source VCC, and resistance R.

Title: Frame filtering system
Inventor: WATANUKI TATSUYA
IPC: H04L12/46
Filed: 1994-06-13
Abstract: PURPOSE:To improve repeating processing performance by improving the processing efficiency of a CPU, in a brouter. CONSTITUTION:The filtering part 31 within a port part A 4 performs a decision for the received frame and performs an instruction for each MAC part 30 by a flash signal line 32, a router signal line 301 or a bridge signal line 302. The MAC part 30 processes the frames in accordance with the instruction, transmits the only frames for which routing processings or bridge processings are required and delivers the frames to a CPU 2. Thus, the frames which are not necessary to be processed by a brouter device are destroyed in a port part. Because the port part instructs the CPU 2 as to which of the routing processing or the bridge processing should be done also for the received frames, the processing performance of the brouter is improved.

Title: Dynamic ram driving circuit
Inventor: KURITA TOSHIYUKI
IPC: G11C11/34
Filed: 1983-07-20
Abstract: PURPOSE:To make a simple circuit read data faster by giving common addresses to two dynamic RAMs, also giving their row addresses and column address strobing (RAS), (CAS) signals which are always the same, and giving output control signals by converting them. CONSTITUTION:When RAS signals are dropped after giving row addresses first on an address signal line; then CAS signals are dropped after giving the column addresses on the address signal line, data-1 are outputted from a dynamic RAM31 on a data line-35 in lagging by a column access time tCAC. In this case, a control signal OE-1 must be set at a ''L'' level before an output control signal access time tOAC1 earlier than the time the data-1 are outputted. Then the OE-1 is set at an ''H'' level; the output of the data-1 is forbidden; and then the output control signal OE-2 is dropped to allow outputting the data-2 from the dynamic RAM-32 to the data line-35. The data-2 is, after the OE-2 falls and after the lapse of tOAC2 time, outputted, and this relationship of tCAC>tOAC enables the data-2 to be read at a higher speed than in the past.

Abstract: PURPOSE:To expand a measurable range of an object to be measured simply by attenuating an irradiation light to a reference reflector and reflected light from the reference reflector so that an intensity of reference light at interference time reaches a specified ratio with respect to an intensity of a signal light. CONSTITUTION:A beam splitter 3 and a neutral density filter 4 are arranged in an optical path of light which is divided in two with a beam splitter 1 to irradiate a reference mirror 2. Reference light to the reference reflector 2 and /or reflected light from the reference reflector 2 are attenuated so that an intensity of reflected light from the reference mirror 2 at interference time reaches a specified ratio with respect to an intensity of reflected light from an object to be measured. This means the existence of the intensity of the reference light to maximize a range of an intensity of a signal light with a beat frequency detectable. This enables the maximizing of a measurable range of the object to be measured only if the intensity of the reference light is set at a specified value beforehand.

Abstract: PURPOSE:To integrate a semiconductor device by restricting bird's beak and prevent stress from occurring by forming a second oxidation resistant mask layer at the side wall of a first oxidation resistant mask layer which is formed on a semiconductor base. CONSTITUTION:A second oxidation resistant mask layer 3 is formed at the side wall of a first oxidation resistant mask layer 2 which is formed on a semiconductor base 1 and a semiconductor layer 4 is formed at the side wall of this second oxidation resistant mask layer 3 for performing oxidation.

Abstract: PURPOSE: To decrease noises and prevent the seizure during the shut-off operation, by enclosing rotary rubber vanes with a first and a second casings.  
     CONSTITUTION: Liquid discharged by the revolution of the rubber vanes 13 is temporarily reserved in a discharge chamber 17 defined by the first casing 10 and the scond casing 17 and is then discharged from a discharge port 18. Because the first casing 16 and is then discharged from a discharge port 18. Because the first casing 10 containing the rubber vanes 13 is surrounded by the discharge chamber 17 containing the liquid, the liquid serves as a silencer to greatly decrease the noise due to the rubber vanes 13 and moreover suppresses the heating due to the friction between the rubber vanes and the first casing. Since the quantity of the liquid in the discharge chamber 17 is much higher than that in a pump chamber 21, the quantity of retained water is large. Therefore, the rise in the liquid temperature during the shut-off operation is delayed and the seisure is prevented.
