Title: Electric charge transfer device
Inventor: OZAKI TOSHIBUMI
IPC: H04N5/335
Filed: 1984-11-26
Abstract: PURPOSE:To reduce the quantity of noise electric charge due to the thermal noise of a reset gate to obtain a high S/N by providing an inverting amplifying circuit which takes a floating capacity for signal detection as the input and has the gate of a reset MOS transistor TR as the output. CONSTITUTION:The inverting amplifying circuit consists of a load MOSTR4 and a river MOSTR5. The signal electric charge converted photoelectrically by a photo diode 2 passes a vertical CCD1 and a horizontal CCD3 and is transferred to a capacity 9 of a detecting node and is sampled and held and is outputted to a terminal 11 by a source follower consisting of a sensing MOSTR7 and a resistance 8. Thereafter, the inverting amplifying circuit is operated, and the potential of the detecting node is reset through the reset MOSTR. Since the reset potential of the detecting node is kept constant to prevent the crosstalk between signals, the bias electric charge is inputted from a horizontal CCD input part 12. Thus, a solid-state image pickup element where the noise electric charge due to the thermal noise of the reset MOSTR is reduced to obtain a high S/N ratio is realized.

Title: Separation of plasma and apparatus used therefor
Inventor: HATTORI HIROYUKI
IPC: G01N33/48
Filed: 1986-10-17
Abstract: PURPOSE:To prevent the lowering of separation efficiency, by rotating an outer cylinder with a separation film fixed to move blood cells outward with the action of a centrifugal force. CONSTITUTION:Blood is introduced into a space between a separation film 2 and an outer cylinder 3 through a piping 9 and the outer cylinder 3 is rotated at a high speed. Consequently, under receiving a centrifugal force, blood cells are moved to the surface of the outer cylinder 3. After the blood cells and plasma are separated roughly, the plasma builds up in an inner cylinder 1 with the separation film 2. The plasma in the inner cylinder 1 is taken out through a piping 10. The blood from which the plasma has been separated is take off through the piping 9. The blood cells and the plasma are separated roughly with the action of a centrifugal force on the blood cells to reduce the density of the blood cells on the surface of the film 2 and thus, the clogging of pores of the film 2 is prevented thereby eliminating a drop in the separation capacity.

Title: Pressing force variable control method for wiper
Inventor: MOCHIZUKI WATARU
IPC: B60S1/32
Filed: 1990-09-18
Abstract: PURPOSE:To prevent incorrect function of a wiper caused by an abnormal signal by regarding a value, written in a memory, as a read value if a signal from a pressing force sensor varies to an abnormal value which does not belong to a normal signal value. CONSTITUTION:In a pressing force increasing/decreasing means, a motor 14 is controlled by a control circuit 20, and, through reciprocal motion of a slider 12, a coil spring 8 is elongated or contracted via both a lever member 9 and a connecting member 11 in order to adjust the energizing force of a wiper arm 2, thereby controlling the pressing force of a wiper blade 3 to a glass surface 4. In the control circuit 20, a vehicle speed pulse signal from a vehicle speed sensor 21 is inputted to set the target pressing force for every prescribed vehicle speed range, and the target pressing force is compared with the signal from a pressing force sensor 18 in order to generate a control signal. In this case, a measured value, which is obtained when pressing force target value and the detected value coincide with each other and when the motor 14 is stopped, is written into the memory, and, if the measured value varies to an abnormal value during this motor-stop-state, the value written into the memory is regarded as a normal read value, thereby continuing the control.

Title: Stability measuring instrument
Inventor: MAEDA TORU
IPC: G01C21/16
Filed: 1998-09-02
Abstract: PROBLEM TO BE SOLVED: To measure the stability for a hull under navigation by dividing the oscillating velocity obtained by integrating the output of an accelerometer by the oscillating angular velocity obtained from the output of a rate sensor, thereby determining an oscillating radius. SOLUTION: An oscillating computing part 103 corects rotational angular velocity dθ/dt from a rate sensor 101 to cormpute oscillating angular velocity dθs/dt. The component of the rate sensor 101 during outputting is integrated by repeating integration and accumulated on the angle as an error. Therefore, the accumulation of an error in the angle is restrained by an adder. An oscillating angle θs is determined by oscillating angular velocity dθs/dt integrated with an integrator and g.sinθs is calculated with the correcting part 104 for acceleration velocity. The g.sinθs is subtracted and corrected by oscillating acceleration Ac which an accelerometer 102 outputs and integrated by the integrator, and the tangential component Vs of the oscillating velocity is determined.  An oscilating radius computing part 105 divides the tangential component Vs by oscillation angular velocity dθs/dt to determine an oscillating radius.

Filed: 1988-09-30
Abstract: PURPOSE:To realize the reduction of installation area as well as the improvement of workability and thermal efficiency, resulting from the compacting of a device, by a method a melting burner is provided at the lower side surface of a preheating tower unit so that a flame is injected obliquely downward from the lower part of the preheating tower unit toward a melting unit. CONSTITUTION:Thrown melting material is changed into a preheating tower unit 2a and a melting unit 2b. Reducing high-temperature and strong flame, injected out of a melting burner 4, arrives at the deep part of the material so as to envelope the whole periphery of the melting material in the melting unit 2b whereby the melting material in the melting unit 2b is melted at a high speed. The strong flame is injected obliquely downward toward the melting unit 2b and, therefore, the rising hot air in the melting unit 2b is hindered and strong turbulent flow is generated in the melting unit 2b whereby the high- speed melting of the melting material may be promoted. Hot air, rising from the melting unit 2b, rises through the preheating tower unit 2a while being mixed by receiving the effect of the turbulent flow the chance to make contact with the melting material is increased whereby the hot air rises while realizing big preheating effect.
