IPC: H03L7/093
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To generate a stable output signal in synchronizing with an input signal by inputting the output signal of a voltage control oscillator(VCO) to a phase detection circuit and forming a feedback circuit. SOLUTION: An inner clock signal (f) outputted from VCO 4 is frequency- divided in a frequency-dividing circuit 5 and it is inputted to the other input terminal of the phase detection circuit 1. Then, the feedback circuit is formed. PF 2 inputs an error signal (c) outputted from the phase detection circuit 1 and outputs a control signal (d) obtained by smoothing the error signal (c). A sample-and-hold circuit 3 inputs the control signal (d) and holds a control signal (e) in accordance with a sampling pulse (h) outputted from a pulse generation circuit 6. Since the control signal (e) is given to VCO 4 from the sample- and-hold circuit, 3 while the input signal is not transmitted with such constitution, the output signal (f) is not stepped out and the stable output signal (f) synchronized with the input signal (a) can be obtained.

IPC: F02B37/24
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To correctly maintain operation of a turbo charger without providing a supercharger rotational frequency sensor or the like. SOLUTION: A nozzle vane of a turbo charger 35 provided on a diesel engine 11 is opening-controlled by duty control of an applied voltage to a solenoid of an electric vacuum regulating valve.

Title: Structure for vertically swinging lift arm of working vehicle
Inventor: FUKUMOTO TOSHIYA
IPC: F15B11/08
Filed: 1991-06-26
Abstract: PURPOSE:To enable correct stop of a lift arm at a position slightly lower than the upper limit of the arm even if there is a discrepancy between the lift arm position and an angle sensor position by memorizing the upper limit of the swinging angle of a lift arm in a specific state.

Title: Bearing plate having conical surface
Inventor: KAMIYOSHI SATORU
IPC: E04C5/12
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To sufficiently exhibit an effect of prestress by forming one surface of a bearing plate having a conical surface as a pressure receiving surface and the other surface as a circular pressure transmitting surface, and boring an inserting hole of a tendon on a straight line orthogonal to the pressure receiving surface. SOLUTION: A plate-like bearing plate composed of one surface of a pressure receiving surface 1 and the other surface of a circular pressure transmitting surface 2 is molded, an inserting hole 4 of a tendon 3 is bored on a straight line L orthogonal to the pressure receiving surface 1, and the peripheral edge of the pressure receiving surface 1 continues with the pressure transmitting surface 2 side via a conical surface 5.

Title: Dead water preventing double pipe system
Inventor: UJI SUKEO
IPC: E03B11/10
Filed: 1992-05-20
Abstract: PURPOSE:To make unnecessary a piping space for a return pipe, by providing an outer pipe closed at both ends, which is allowed to branch for water supply by connecting the one end side thereof to a water supply tank through piping and by closing the other end side thereof, and an inner pipe, which is provided in the outer pipe, is allowed to communicates with the inside of the outer pipe at the other end side of the outer pipe and is connected to the water supply tank by piercing the one end side of the outer pipe, and a means for conveying water in the inner pipe. CONSTITUTION:Water is not discharged from any of faucets 11 while not used because of the closure of a building or the like. However, when a return pump 19 is operated, the water in an outer pipe 5 is allowed to circulate, little by little, to a water tank 1 placed at a high position through an inner pipe 7 and a return pipe 13, and thus the water always is in the state of circulation and does not stay. When the abnormality of water quality is detected by sensors 15a, 15b, chlorine is impregnated into the water in circulation by a chlorinator 25, and thus the deterioration of the water quality is not produced even if the water is not used in a long period of time. Therefore, a piping space for the return pipe is made unnecessary since circulation piping is done with the double pipe 9, and labor required for its piping can be reduced by half.

Title: Microprogram control unit
Inventor: KAMIMOTO SHIGEMI
IPC: G06F11/14
Filed: 1979-11-29
Abstract: PURPOSE: To enhance the effect of retry, by changing the working condition of the arithmetic control circuit based on the designation of the microprogram of a control memory when the error detector detects an error.  
     CONSTITUTION: The error caused in the arithmetic execution circuit 54 is detected by the error detecting circuit 55. Thus the circuit 55 controls the address forming circuit 56 via the control line 201 to secure a branching action out of the normal microprogram routine. With this branching action, the specific microorder is read to indicate the retry action through the control circuit 12. Furthermore, the microorder gives an indication so that the circuit 54 may be operated in the working condition different from the normal state. Thus the circuit 12 controls the circuit 54 under the conditions indicated, e.g., with a control interval longer than the normal one. As a result, the effect of retry can be enhanced.

IPC: H03K5/08
Filed: 1988-06-24
Abstract: PURPOSE:To eliminate an excess waveform corresponding to the rise time of a reference voltage to shorten the length of a signal by connecting a delay circuit to one of two input terminals of a comparator in a digital signal waveform shaping circuit where an integrating circuit is connected to the other input terminal of said comparator. CONSTITUTION:An input signal I is inputted to one input terminal 2 of a comparator 1 through a delay circuit 5, and the input signal is inputted to the other input terminal 3 through an integrating circuit 4. A waveform A4 is outputted from the integrating circuit 4, and a waveform A3 is outputted from the delay circuit 5. Though a time B2 is required for rise of a reference voltage B1 as the integral output, the delay circuit 5 outputs the waveform A3 obtained by delaying an input waveform A2 by the rise time B2. As the result, the waveform A3 from the delay circuit 5 is applied to the comparator 1 after the voltage of the integral output reaches a reference voltage B1, and a waveform A6 is outputted to an output O of the circuit. In this output waveform A6, the excess waveform corresponding to the rise time B2 in an output waveform A5 of a conventional circuit is eliminated.

Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a nozzle tip which is capable of stably spinning a glass fiber having a flat cross section as high in a flattening ratio as >=4.0. SOLUTION: The nozzle tip 13 to be disposed at the rear surface of a nozzle plate 12 is provided with a nozzle hole 24 of such a cross-sectional shape formed by connecting two nozzle holes having a flat cross section to a V shape. Nozzle hole wall notched parts 25 of a recessed shape are formed at nozzle hole walls on each one side of a straight portion forming the two sides of the V shape. The molten glass flowing down the nozzle hole is rapidly cooled at the notched parts 25, by which the phenomenon to round the molten glass drawn out of the nozzle hole is suppressed and the production of the glass fiber having the flattening ratio nearly equal to the flattening ratio of the nozzle hole is made possible. The discharging of the molten glass from the entire part of the nozzle hole 24 may be stabilized by bending the nozzle hole 24 to the V shape.

Inventor: IKEMORI KUNIO
IPC: B60H1/00
Filed: 1979-11-29
Abstract: PURPOSE:To improve remarkably the air heating effect and dehumidifying effect by bringing first the air in the passenger compartment into contact with the external air for the purpose of rapid cooling and dehumidification and then feeding the cooled air to a heater unit and discharging thus heated air into the passenger compartment. CONSTITUTION:In the air heating when a fan is actuated and a shutter 7a is opened, the warm air in the passenger compartment is introduced from an air outlet 7 through a duct 3 and a heater opening into the heater unit 1. In this instance, as the duct 3 has a plurality of external air inlets 4a through which the external air is taken therein, the hot air of the passenger compartment is brought into contact with the cool external air while it is flowing through the duct 3 and rapidly cooled and dehumidified. Thus cooled and dehumidified air is then fed into the heater unit 1, where it is heated by a heater core 1a, and finally discharged into the passenger compartment out of an air discharge opening 1b. Thus the heat efficiency can be much improved and the window clouding can be prevented to a great extent due to the low humidity of the heated air.
