Title: Optical voltage sensor
Inventor: SHINDO SHOTARO
IPC: G02F1/03
Filed: 1984-09-11
Abstract: PURPOSE:To improve characteristics by providing two voltage measurement systems which are equal in half-wavelength voltage and different in phase difference and measure the same voltage on the same substrate. CONSTITUTION:The two voltage measurement systems A and B which are equal in half-wavelength voltage and difference in phase difference are provided on the same substrate. Those measurement systems A and B are applied with output light from the same light source 50 and also applied with a measurement voltage from the same signal source 40, and measurement light output signals P1 and P2 of those measurement systems A and B are converted by photodetecting elements 60 and 70 into electric signals, which are applied to a signal processing circuit 80. Those signals P1 and P2 have a phase difference based upon the difference in length between photoconductor bodies. For example, when the measurement voltage applied from a signal line 40 is lower than a half-wavelength voltage, it is nearly proportional to the measurement voltage of the signal P2 of the measurement system B. The noise component of the signal P1 of the measurement system A, on the other hand, is obtained from a specific expression and calculated by the circuit 80 to obtain a measurement output; the noise is canceled and a voltage measurement with a superior S/N is taken.

Abstract: PROBLEM TO BE SOLVED: To arrange not to refuse the entry of any one who may be late while securing security in a non-contact type entry control system and prevent the generation of repeated useless environmental noise and prevent useless consumption of a battery. SOLUTION: When an ID code is received by radio from an ID card 30, for example, a name card of someone who is approaching, it is determined whether or not the received ID code is conforming to a permissible ID code stored in a door controller 10. When they agrees with each other, an unlocking signal is output while a locking signal is output when they fail to agree with each other, thereby controlling an electric lock 20. Unless the door is opened or closed while it is locked, the determination of the ID code is made for every specified time interval. If it is the permissible ID code, the output of an unlocking signal will be continued. If it is not the permissible ID code, a locking signal will be output. When the door is opened or closed within a specified time, a locking signal will be output after the door is close.  After locked, the door will return to the initial ID code's wait state.

Title: Operation monitoring device for soot blower
Inventor: ENOMOTO HIROYASU
IPC: F23J3/00
Filed: 1983-10-14
Abstract: PURPOSE:To early and reliably detect trouble occurring in a soot blower, by a method wherein the current value of a motor for driving a soot blower is detected at each time division, the result is compared with an allowable value set at such division, and if it exceeds the range of the allowable value, an abnormal signal is outputted. CONSTITUTION:When, in order to conduct soot blowing, an electromagnetic switch 3F for advancing is closed and a motor 1 is actuated, an auxiliary contact 8, simultaneously, is also closed and a timer 9g is started to be operated. According to the procedures of an ROM9e, a CPU9d stores in an RAM9d values, continuously following an electric current value at a current time from a signal converter 7, in order throughout an entire forward and backward range. Thereafter, based on the memory of a plurality of the preceding and before motion times of a soot blower, the maximum allowable value of a load applied on the motor 1 is computed. Such limit value is compared with a value stored in the RAM 9f once, and if the result exceeds the limit value, it is determined that a trouble has occurred in the soot blower. A trouble is displayed on a CRT10, a display lamp 11 is lighted ON, and a buzzer 12 is sounded to alarm the occurrence of a trouble.

Title: Vaporization burner
Inventor: MIYAHARA KINGO
IPC: F23D11/06
Filed: 1987-07-29
Abstract: PURPOSE:To enable continuance of stable vaporization combustion over a long period, by a method wherein secondary air for combustion horizontally injected through the horizontal peripheral end parts of an air-fuel mixture cylinder and an injection air guide cylinder is supplied to the outer periphery of a vaporizing cylinder as it is decreased in a pressure and decelerated by means of a vortex generating rise annular wall. CONSTITUTION:Secondary air for combustion is injected with a force in a horizontal direction from between the horizontal plane of an air-fuel mixture cylinder 115 and an injection air guide cylinder 122. However, by colliding the secondary air for combustion with an erected vortex generating rise annular wall 127 right before it is injected, the secondary air is decreased in pressure and sharply reduced in velocity of flow, and burnt up as it is joined with a vaporizing combustion flame injected and burnt through a flame injection port 106. Thus, since diluted air-fuel mixture, about to be injected in a horizontal direction from an air-fuel mixture diluting chamber 121, is slowly injected toward the outer periphery of a vaporization cylinder 109 as it is brought into a turbulence state, an vaporization combustion flame, injected through the flame injection port 106 for combustion, is smoothly burnt up without interference. The whole of the vaporizing cylinder 109 is properly heated, and a given amount of air-fuel mixture can be stably generated over a long period.

Title: Optical system driving method in image reader
Inventor: ISHII HIROSHI
IPC: G03B27/50
Filed: 1989-07-26
Abstract: PURPOSE:To evade the danger of collision, to make an optical system noiseless, to stabilize CPM (the number of copies/min.), and also to stabilize an operation for stopping at an initial position by driving the optical system from outgoing motion start to its approach running start under PLL (phase locked loop) control. CONSTITUTION:A second reference signal is a signal for a high speed return motion and for rotation which is higher than a first reference signal for a constant speed outgoing motion (at the time of an outgoing motion); a DC motor 7 rotate at a high speed while its rotating frequency is controlled so that speed is constant, and the optical system 1 is returned at a constant speed. When a photosensor 13 detects an actuator 15, a control circuit 11 sends a PLL release signal to a PLL circuit 10, and also applies the brakes to the DC motor 7. Additionally the control circuit 11 sends a third reference signal to the PLL circuit 10, the DC motor 7 is driven at a speed lower than a constant speed, at which it runs at the time of the outgoing motion; the optical system 1 is approached toward a stop position, and is completely stopped. Thus, the danger of collision can be evaded, the optical system is made noiseless, the CPM is stabilized, and an operation for stopping at the initial position can be also stabilized.
