In the course of this hot rolling, forced rolling is performed in the austenite unrecrystallized region at <=40% cumulative reduction of area based on finish thickness, followed by cooling down to <=200 deg.C. Subsequently, this steel stock is heated to a temp. between the Ac3 transformation point and 950 deg.C to undergo hardening and subjected to tempering treatment at a temp. not lower than the Ac1 point. By this method, the heat treated high tensile strength steel product excellent in toughness, particularly in toughness at low temp., can be obtained.

Title: Output voltage overshooting preventive circuit for power circuit
Inventor: KONDO NORIFUMI
IPC: G05F1/44
Filed: 1995-04-26
Abstract: PURPOSE: To prevent overshoot voltage from being produced in the output voltage of a power circuit by providing the power circuit with a circuit that increases the amount of the output voltage fed back to a power supply control circuit only at the time of raising the output voltage. CONSTITUTION: An output voltage overshooting preventive circuit 4 consists of a transistor Tr1 , resistors R3 , R4 , and a capacitor C1 . The preventive circuit is added to a power circuit. As a result, when the output voltage of the power circuit starts to rise, a charging current flows to the capacitor C1 through the resistor R3 , and the transistor Tr1 is turned on. As a result, a photo camera PS1 carries a current IR4 limited by the resistor R4 , and the potential increases at point B. Since a control circuit 2 gets feedback as if the value of voltage were higher than the actual output voltage, the production of overshoot voltage is prevented at the time of raising the output voltage.

Title: Work timber sorter in deburring apparatus
Inventor: SAKANO OSAYUKI
IPC: B24B21/00
Filed: 1986-05-04
Abstract: PURPOSE:To aim at automating the sorting of work timber with the use of a device for sorting work timber having an upper surface on which burrs are produced due to press work or the like, by providing such an arrangement that working timber having its upper surface on which burrs are produced is alone discriminated and is fed to a grinding device. CONSTITUTION:A detecting device 20 detects the condition of opposed surfaces of work timber W fed from a feeder. A central control device discriminates the presence cf burrs on the opposed surfaces in accordance with an output signal from the detecting device 20. If burrs are present on the upper surface, a diverting device 30 is set to an open position to introduce the working timber W into a grinding device. Meanwhile, in the case of no burrs present on the upper surface, if the work timber W would be fed direct into the grinder, the upper surface would be ground so that the thickness of the work timber would he unsuitable. Accordingly, the diverting device is changed over to a discharge position to discharge the working timber W. Thus discharged working timber W is again fed into the feeder. Accordingly, working timber W having its upper surface on which burrs are present, is alone fed into the grinding device for grinding out the burrs.

Title: Signal transmitter
Inventor: NAGAMOTO SHUNICHI
IPC: H04L27/00
Filed: 1988-04-26
Abstract: PURPOSE:To attain accurate signal transmission even under the condition with much deteriorated S/N against a disturbing noise having the same frequency as the carrier frequency of a transmission signal by applying AM modulation to the carrier signal having two carrier signal frequencies synchronously with the tone signal by means of a binary logic data for further transmission. CONSTITUTION:The 1st modulation means 5 applies FM modulation to a carrier signal fc so as to obtain the 1st carrier signal frequency fc1 in case of the in-phase timing of a tone signal ft and to obtain the 2nd carrier signal frequency fc2 in case of the opposite phase timing of the tone signal ft. Then the 2nd modulation means 6 sends the carrier signal subject to FM modulation by using a binary logic data desired further to be sent. The receiver uses filter means 10, 13 to select only the signal component tuned to the carrier signal frequencies fc1 fc2 and filter means 12, 15 demodulate the signal after envelope detection synchronously with the tone signal frequency ft into a binary logic data and an arithmetic means 16 applies a prescribed processing. Thus, it is possible to reject a noise except that having two carrier signal frequency components synchronously with the tone signal frequency and the signal transmitter with high reliability is obtained.

Abstract: PURPOSE:To obtain an image forming device using a photosensitive body which is constituted to a relatively small size and has the color separating function, by constituting at least an electrifier for reelectrification and a uniform exposure device for uniform exposure just after reelectrification into one unit. CONSTITUTION:An electrifier 7Y and a uniform exposure light source like a fluorescence lamp of a uniform exposure device 5G are attached to a unit frame 8 formed with a synthetic resin so that the uniform exposure light source is placed at the rear of the electrifier 7Y. An optical path is formed between the side wall of the electrifier 7Y below in the rotation direction of a photosensitive body 1 and that of the unit frame 8 above it, and they are so unitized that the light from the uniform exposure light source passes this optical path and is made incident on the surface of the photosensitive body 1. Since the electrifier 7Y and the uniform exposure device 5G are unitized, the gap between a developing device 6Y and a following developing device 6M is narrowed to miniaturize the image forming device. Further, the productivity is enhanced to reduce the production cost.
