Abstract: PURPOSE:To reduce the mass and eliminate deviation in loading and to make a stable scan and improve response by rotating a mirror directly by a rotating shaft. CONSTITUTION:A scanning device consists of the rotating shaft 222 and a slide shaft 223 which are arranged opposite each other across and optical path, a rotary mechanism part which rotates the rotating shaft 222 in synchronism with the rotating operation of an image carrier (photosensitive drum) 24, a reflecting mirror 225 provided atop of the slide shaft 223, a moving mechanism part which is positioned at the rear end of the slide shaft 223 to slide this shaft and switches and positions the reflecting mirror 225 on the optical path or at a stand-by position selectively, and a coupling mechanism part which couples the tip of the slide shaft 223 with the rotating shaft at the forward movement position of the slide shaft. Consequently, only the mirror is supported at the tip of the shaft, so an output for its operation is small, accurate rotating operation is enabled, and no rotary moment is impressed to the shaft. Consequently, the durability to disturbance such as vibrations is high and high reliability is obtained.

Abstract: PURPOSE:To increase heating power and to enable high frequency quenching for a short time by quenching a work by a heating coil, which is sealed to magnetic field at the upper and lower faces thereof, and injecting cooling water from water cooled jacket adjoining to the coil. CONSTITUTION:The work, such as cam shaft 6, is inserted into the heating coil 1 and high frequency power is impressed to the heating coil 1, and the cam shaft 6 and coil 1 and the water cooled jacket 4 connected it, are relatively shifted.

Title: Facsimile equipment
Inventor: TAKAHASHI MASAKATSU
IPC: H04M11/00
Filed: 1990-03-15
Abstract: PURPOSE:To eliminate the need for the start operation of facsimile communication by releasing the talking state so as to execute the facsimile communication automatically when a facsimile signal is received from a destination and a telephone set responds to an incoming call. CONSTITUTION:Upon the detection of a CNG signal of a destination, a facsimile equipment 1 closes a switch S1 to throw moving contacts of a changeover switch S2 to the position of b1, b2 and a tone output circuit 111 outputs a constant tone signal. A telephone set 2 receives a DC current from a DC current supply circuit 106 and a prescribed signal tone is outputted from a receiver by a tone signal outputted from the tone output circuit 111. On the other hand, a facsimile signal processing section 104 forms a signal path with a telephone line to execute prescribed facsimile communication with a destination facsimile equipment. Thus, the start operation of the facsimile communication when the telephone set responds to the incoming call is not required.

Title: Method for working curved surface of ultrasonic vibrator
Inventor: KAWAMATA IWAO
IPC: H04R31/00
Filed: 1986-03-20
Abstract: PURPOSE:To simply obtain curved surface ultrasonic vibrators having small variance of the thickness of curved surface piezoelectric bodies and small variance of the thickness of electrodes at high reproducibility by holding a flat plate ultrasonic vibrator between a concave surface block and a convex surface block, deforming the flat plate ultrasonic vibrator by heating and forming a curved surface ultrasonic vibrator. CONSTITUTION:If a flat plate ultrasonic vibrator made by providing electrodes on both sides of a flat plate piezoelectric body 3b cut at high thickness accuracy is held between a concave surface block 5 and a convex surface block having a radius of curvature R and heated, plastic distortion is formed just before brittle fracture due to load stress. Distortion starts at three places, that is near the contact line with the convex R surface block 7 and two places near the contact line with concave R surface block, and speed of distortion near the contact line with the convex R surface block 7 is more than double compared with other two places as the load differs by twice. Accordingly, the center portion of flat plate ultrasonic vibrator starts distortion faster than other parts. With generation of distortion, load applied per unit area becomes smaller and speed of distortion decreases. After lapse of a certain time, the flat plate ultrasonic vibrator is deformed to a curved face vibrator having a radius of curvature R.

Title: Infrared detector
Inventor: JINNO MARUO
IPC: G01J5/0805
Filed: 1986-03-20
Abstract: PURPOSE:To transmit incident infrared rays alone with a certain wavelength to match with an optical shutter with the wavelength thereof, by arranging the optical shutter to be composed of an electrooptical element and a voltage applying means for applying a cycle electric field to the element. CONSTITUTION:A plate 25 comprising an electrooptical element PLZT is sandwitched between polarizing plates 21 and 22 with the directions of polarization thereof orthogonal to each other. Two parallel grooves are formed in the plate 25 and electrodes 23 and 24 are formed in the grooves. Only components of light along the direction of polarization of the polarizing plate 21 among those reaching it are allowed to be transmitted therethrough 21 and reach the plate 25. While no voltage is applied between the grooves of the plate 25, there is no change in the direction of polarization and of the light after passing through the plate 25, none is allowed to pass through the polarizing plate 22. When a voltage is applied to the plate 25, the plate 25 turns the polarizing plane of an incident light. Thus, the light leaving the plate 25 can pass through the polarizing plate 22 by properly setting the voltage to be applied to a shift the angle of rotation of the polarizing plane to 90 deg..

IPC: F02D45/00
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To allow even a NOx concentration sensor of solid electrolyte type for detecting NOx concentration in accordance with the amount of oxygen passing therethrough to prevent generation of misfire and white smoke during fuel recovering. SOLUTION: The unburned HC obtained by the fuel injection subsequent to main fuel injection is supplied as reduction agent to NOx catalyst. The above type of sensor 83 detects concentration of NOx contained in the upstream of the catalyst. The NOx emission amount is actually measured in accordance with the detected value. Then the required HC amount is obtained in accordance with the difference or ratio between the actual measurement HC/NOx ratio and target HC/NOx ratio as the ratio of the HC emission amount with respect to NOx emission amount. Based on the required HC amount, the injection amount subsequent to main injection is calculated. Control means 92 feedback controls opening degree of an EGR valve such that the actual measurement NOx emission amount matches at the target NOx emission amount.  The feedback control during deceleration is stopped to allow the control means 92 to execute open control of the EGR valve opening degree.
