IPC: B05B1/34
Filed: 1993-08-09
Abstract: PURPOSE:To atomize a liquid as fine particles at the large controllable width for the atomization quantity by turning the liquid which is flown in from a revolving introducing opening after being pressurized in a liquid supply part a revolving chamber, into the revolving stream and jetting it from a jetting hole to the outside in liquid film state while revolving with a hollow reverse conical film. CONSTITUTION:The revolving introducing opening 10 is provided so as to be in contact with the revolving chamber 9 and is connected to a pump 12 with a liquid passage 11 at the upstream side and the jetting hole 14 is provided at the end face of the down stream side of a body 13 constituting the revolving chamber 9. The liquid supplied to the pump 12 is pressurized to a prescribed pressure, flows in the revolving chamber 9 from the revolving introducing opening 10 at a prescribed speed through the liquid passage 11 to from the revolving stream and is jetted from the jetting hole 14 to the outside while revolving with the hollow reverse conical film. Because the speed of the revolving stream in the revolving chamber 9 is increased when the atomizing quantity is small and the liquid is jetted from the jetting hole 14 while revolving with the hollow reverse conical film, the liquid film is divided into small pieces by shearing force and the liquid is atomized at the large controllable width for the atomizing quantity.

Title: Alternative current constant voltage device
Inventor: SHIRAISHI TOMOO
IPC: G05F1/12
Filed: 1988-08-08
Abstract: PURPOSE:To efficiently execute the fluctuation compensation of a load voltage by using a reverse converter and compensating the fluctuation of the load voltage. CONSTITUTION:When a power source voltage VS is lower than a rated voltage VR, a reverse converter 10 executes reverse converting operation (inverter operation) with the frequency of 10-20kHz in correspondence to an output voltage signal VF of a control amplifier 9. As a result, a compensating voltage VH2, which corresponds to difference between the rated voltage VR and a load voltage VL, is generated from the reverse converter 10 and this compensating voltage VH2 is added to the power source voltage VS of an alternative current power source 1 and impressed to a load. Thus, since the reverse converter of low loss is used and the fluctuation of the load voltage is compensated, the efficiency of the fluctuation compensation can be improved.

IPC: F02D45/00
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To detect abnormality of a variable valve unit easily and accurately. SOLUTION: In this detection system, a crank angle sensor 9 is provided near a rotor 8 which is mounted on a crankshaft 7, The crank angle sensor 9 detects engine speed and the like of an internal combustion engine 1. In this case, for example, occurrence of misfire is detected from the detected engine speed change, and frequency thereof is monitored by ranges of low-speed low- load operation, middle-speed middle-load operation, and other operations of the engine 1. When misfire occurrence frequency is increased only in the low- speed low-load operating range, it is judged that a high speed cam 31 in an exhaust system is locked. When misfire occurrence frequency is increased in the low-speed low-load operation range and in the middle-speed middle-load operation range, it is judged that the high speed cam 31 in an intake system is locked.

Title: Proximity fuse for missile
Inventor: OKUGAWA HARUKI
IPC: F42C13/04
Filed: 1988-08-08
Abstract: PURPOSE:To avoid faulty detonation and detonate a warhead at a relative position whereat warhead effect becomes maximum at all times by a method wherein the timing of generating a detonating signal is regulated in accordance with an approaching speed or the relative position between a missile and a target. CONSTITUTION:When a judging circuit 12 has received the directional angle signal of antenna from an angle detecting circuit 10, an approaching speed signal from a doppler receiver 4 and a target scale signal from a RCS estimating circuit 11 and has judged that a target is a high-speed small target such as a tactical missile or the like, a detonation regulating circuit 13 generates a detonating signal when a relative distance between a missile and the target becomes within a predetermined distance even if there is no signal from a receiver 7 for a fuse. When the judging circuit 12 has not judged that the target is the high-speed small target, the detonation regulating circuit 13 regulates a delay time based on the approaching speed signal from the doppler receiver 4 by the relation between the approaching speed and the detonation delay time, which is determined by the directivity characteristics of an antenna 5 for the fuse detecting the approaching target and the dispersion distribution of a warhead, the speed of fragments and the like, and generates a detonating signal after receiving a target detecting signal from the receiver 7 for the fuse.

Abstract: PURPOSE:To remove deviation of probability to generate an index from a vector quantizing means and to improve efficiency for encoding by executing variable length encoding for outputs (index and identification code) for the unit of a vector in the vector quantizing means. CONSTITUTION:The index from a vector quantizer 11 is supplied to an entropy encoder 12 as a variable length encoding means and so-called variable length encoding is executed. Thus, the deviation is removed for the probability to generate the index, which is generated since a code vector is used more frequently than the other code vector and the efficiency for quantization can be more improved. In such a case, by monitoring the output of the vector quantizer 11 stored in an output buffer 12a in the entropy encoder 12 and controlling the resolution or quantizing step size of the vector quantizer 11 corresponding to the output, overflow is eliminated.

Abstract: PURPOSE:To optimize the volume of air for the combustion by a method wherein, when the number of the burners to be operated is changed, a correlation table between preset values of air volume and outputs of a proportional valve is also switched over accordingly for the control of the energization quantity of the fan. CONSTITUTION:When a switching by a solenoid type switching valve 12 is effected, a correlation table between preset values of air volume and outputs of a proportional valve 10 is also switched accordingly between one for the combustion with all of the burners 3 in operation and at the time of the solenoid type switching valve 12 being in a deenergized state and another for the combustion with a smaller number of burners 3 in operation and at the time of the solenoid type switching valve 12 being in a deenergized state so that the energization quantity of the fan 4 can be controlled on the basis of a preset value of air volume suited to the number of the burners 3 in operation and also on the basis of the output of a flow sensor 6. Thus the volume of air can be varied to suit the number of the burners 3 in operation and the combustion takes place in a most favorable state.

Abstract: PURPOSE:To obtain excellent workability by forming a form which frames three sides and provides a press-in groove in its longitudinal direction and coating this frame material and glass with a fluid material and then pressing the glass into the press-in groove. CONSTITUTION:One side is preliminarily left over while the other three sides 1, 2 and 3 are connected to an L-shaped coupler 4, thereby forming a form. An engagement press-in groove is installed to the frame members 1, 2 and 3 at the degree of about 45. Liquefied silicone resin is applied to a part where the frame members and glass 6 are placed into direct contact with each other. The glass 6 is pressed into the press-in groove under the condition that the resin is still uncured. The other frame member 8 pressed in while it is being placed over the top of the glass 6. This construction makes it possible to prevent the silicon resin from flowing between the frame members and face bars and inhibit the generation of a clearance.
