Title: Flame detector
Inventor: NAKAYOSHI JIICHI
IPC: G08B17/12
Filed: 1989-07-28
Abstract: PURPOSE:To preclude malfunction and to enable flame detection over a wide range by detecting spectra of nearly CO2 resonance radiation wavelength and in the ultraviolet-ray range. CONSTITUTION:The fish-eye lens 11 of a CO2 resonance radiation detection system 10 has a 180 deg. visual field angle, and an aspherical plastic objective lens 12 forms a fine spot on a detector 13, which has band sensitivity almost at 4.3 mum. Further, an infrared detection system 20 has a fish-eye lens 21, an objective lens 22, and an infrared detector 23 and its band sensitivity is almost at 5.3 mum. Further, an ultraviolet detection system 30 has a fish-eye lens 31, an objective lens 32, and an ultraviolet-ray photoelectron tube detector 33 and its band sensitivity is at 180-260 nm. Then when the output difference between the detection systems 10 and 20 is larger than a reference value, a flame presence/absence judging circuit 50 outputs H from a binary coding circuit 53 and when the output of the detection system 30 is larger than the reference value, a binary coding circuit 54 outputs H. Then an AND circuit 55 judges a flame when both the outputs are H.

Title: Force motor type servo valve
Inventor: WATANABE HARUO
IPC: F15B13/044
Filed: 1982-11-12
Abstract: PURPOSE:To remove heat of a coil of a force motor efficiently and to obtain a high-output servo valve which can respond quickly by enclosing fluid substance having good thermal conductivity in an air gap portion and circulating a cooling fluid in the outer peripheral portion of a magnet. CONSTITUTION:When an electric current is applied to a coil 4 through a feeder line 7, a spool 16 is moved axially as shown by an arrow through a coil bobbin 6 by the action of a force motor 1, so that pressurized oil flows into a control oil chamber 19a through an oil path 22 and a pressurized oil chamber 20, and further flows into one side of a piston through an oil path 23a. On the other hand, pressurized oil on the other side of the piston flows into a control oil chamber 19b through an oil path 23b, and further returns to an oil tank through a return oil chamber 21b and an oil path 24. In this case, a cooling fluid is circulated in a gap 14 among a case 11, a magnet 2 and yokes 3a, 3b, so that heat generated in a coil 5 is transmitted through a good thermal conductive substance 8 in the yoke 3a and an air gap 4, which can avoid an influence upon movement of the coil bobbin 6 and enables high output of the force motor.

Title: Multichannel pwm digital/analog converter
Inventor: SENDA SATOYUKI
IPC: H03M1/82
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To easily obtain a multichannel PWM digital/analog converter which is low-cost and has high performance by constructing a converter, such that the rise of the PWM signal of each channel can be shifted from one another, corresponding to an offset value. SOLUTION: Adders 802 to 804 on and after a CH2 with a 1st channel (CH1) performing zero detection as reference are provided, and a phase difference component to the CH1 is added to the value of each data bus as an offset value and respectively latched to latching circuits 102 and 104. The offset value of each channel is defined as a value, that is mutually different so as to be shifted by αeach among all channels, so that none of the phases of PWM output waveforms overlap. Also, on and after the CH2, each offset detection circuit is used instead of a zero detection circuit 30 of the CH1. The offset detection circuit outputs an Hi level signal, when the counter value of a counter 20 becomes an offset value. The offset value is equivalent to the offset value added by an adder.

Abstract: PURPOSE:To prevent malfunction due to characteristic variation and aging change of components by floating the reference value of a binary coding decision circuit automatically to an optimum value. CONSTITUTION:A signal V1 is inputted to a terminal 1 and compared by the binary coding decision circuit 3 with the reference value from a D/A converting circuit 7 to output a binary-coded signal to a terminal 2. A time comparing circuit 4 performs a comparative decision on times t1 and t2 required for respective output levels in one optional period T and a period comparing circuit 5 decides on whether the one period T is within a specific range or not simultaneously; and an arithmetic circuit 6 performs arithmetic only when the one period is within the specific range according to the result of the time comparing circuit 4 to add one when t1>t2, to subtract one when t1<t2, and to perform neither addition nor subtraction when t1=t2. Then, the D/A converting circuit 7 outputs a decision reference value proportional to said arithmetic output of the arithmetic circuit 6 to the decision circuit 3, and the reference value is floated automatically to the optimum value according to the input signal.

Abstract: PURPOSE:To decrease number of use of photocouplers by connecting an input of one photocoupler for incoming and opposite party replay state detection to a telephone line via a normally closed switch opened at the hook-off of a handset and connecting to the telephone line via a normally open switch opened normally and closed in hooking on the handset. CONSTITUTION:In lifting a handset 4, a relay RY1 is turned off and a relay RY2 is turned on, then the photocoupler 6a is connected to the telephone line via the relay RY2. The opposite party is called and the opposite party lifts up the handset in response to the call, then the polarity of the voltage between the telephone lines is inverted. Thus, the state of the photocoupler 6a is changed in response to the polarity inversion, then the CPU 10 detects the reply state of the opposite party. Since it does not take place that the simultaneous execution of the incoming detection and the opposite party reply state detection is conducted at the same time, then the photocoupler 6a acts like both the detecting functions of incoming and reply. Thus, number of the photocoupler is decreased by one.
