IPC: H01J9/227
Filed: 1993-01-26
Abstract: PURPOSE: To attach a matrix material charged by frictional electricity in terms of electrophotography after attachment of a phosphor material. CONSTITUTION: A face plate panel 12 is washed and cleaned chemically, and an organic electroconductive layer 32 and organic photo-conductive layer 34 are laid over the inner surface of an observing face plate 18. In darkness the layer 34 is charged to a specified positive potential by a corona discharge device 36. A shadow mask 25 is inserted, exposed by a xenon light 38, and allowed to make discharge selectively. The mask 25 is removed and transferred to the first developing device 42. Green emitting phosphor particles charged positively are emitted from the device 42, repelled by a positive charge region of the photo- conductive layer 34, and attached to the region of layer 34 discharged through photo-exposure. The blue and the red emitting phosphor particles are also subjected to the same process.  Then the photo-conductive layer 34 is recharged uniformly with the specified positive potential so that a matrix 23 is prepared. With the recharging, a large voltage contrast is generated for the electric charges in the exposed region of the layer 34. The panel 12 is mounted in a matrix developing device 42', and the particulates of photo-absorptive matrix material charged negatively are in priority attached strongly to the phosphor elements in between on the layer 34.

Title: Solid-state image pickup device
Inventor: KIHARA NOBUTOSHI
IPC: H04N5/335
Filed: 1982-02-27
Abstract: PURPOSE:To reduce the deterioration in the S/N of a picture output signal due to the increase in a dark current at an external temperature, by placing a solid- state image pickup element and a part of a cooling means in a cavity and evacuate the cavity. CONSTITUTION:A thermal conduction shaft 8 is operated to contact a heat sink 11 on a semiconductor fitting base 2, allowing to dissipate heat sufficiently from  a semiconductor base 1 provided with a CCD. The heat sink 11 is detached  from the base 2. Since the cavity 13 is in this state, the bases 1, 2 are interrupted from the surrounding thermally almost completely. The CCD is exposed and  picture information is read out. Since the time required for the readout is one  frame period, the power application is performed during this period only, then  the self-heating of the CCD is minimized. In operating a CCD camera several  times, the temperature of the base 1 is increased due to the self-heating and a  dark current level is increased, then the heat sink 11 is contacted on the base 2  for the heat dissipation. Thus, the deterioration in the S/N of a picture output  signal is reduced and the picture having high resolution is obtained.

Abstract: PURPOSE:To prevent the measured value of an abnormal sensor from exserting influence upon other estimated quantity of state, by finding the relation between estimated quantity of state and sensor values previously in a normal state and estimating quantity of state from the sensor values on the basis of said the relation if an abnormal state occurs. CONSTITUTION:This system consists of a process 1 having various sensors and a process signal input device 2 for inputting measured values from the sensors to a computer 3. Quantity of state in the processor 1 measured by the sensors are inputted and a discrimination on the presence of an abnormal measured value is made; when no abnormal value is found, a more certain estimated state is found by using the relational expression established among various quantity of state and the coefficients of the relation between the estimated quantity of state and measured values are found individually and stored corresponding to the measured values respectively. If an abnormal measured value is found, a relation coefficient corresponding to the measured value is read out and a corrsponding quantity of state is estimated from the coefficient and measured value to prevent the abnormal measured value from exerting influence upon other estimated quantity of state.

Filed: 1999-02-09
Abstract: PROBLEM TO BE SOLVED: To prevent a recording material from wrinkling at the fixing time. SOLUTION: In this fixing device, a toner image is fixed while holding/ carrying the recording material S by a fixing nip part N between a fixing roller 31 and a pressure roller 32. At this time, a pulling-back force applied from the pressure roller 32 is imparted to the rear side of the recording material S. This force is liable to become smaller at the center part, and larger at the end parts. The device is allowed to impregnate oil in only end parts A and A of the cleaning web 35a held in contact with the pressure roller 32 over whole length in the lengthwise direction, excluding the center part B. In such a manner, the coefficient of friction (μ) at end parts on the pressure roller 32 surface are reduced, the back turning force allied from the pressure roller 32 to the recording material S are equalized, therefore the wrinkles are prevented from the occurrence.

Title: Circuit and method for conversion of single-bit digital input data into analog form
Inventor: KAARIN DORUU KABURAA
IPC: H03M1/08
Filed: 1994-03-02
Abstract: PURPOSE: To filter high frequency noise generated through a sigma-delta (E-A) D/A converter to remove it by connecting one end of a discrete electronic element to an operational amplifier and connecting the other end to a reference voltage source or a ground route. CONSTITUTION: When a signal x(0) 24 is equal to '1' in a 1st time period, a contact S2-26 is connected to the reference voltage source VREF 28. When the signal x(0) 24 is equal to '0', a contact S1-30 is connected to the ground route GND 32 and a capacitor CR 34 is short-circuited during the same time period. In a 2nd time period, the whole electric charge in the circuit is redistributed or transferred so that V0 -36 related to each capacitor 22 becomes V0 =-x(k).(CR/Ci). Total transmission relation becomes V0 =(-C1 /CR).x(O).(C/CR).x(1)--(C3 /CR).x(2).(CN/CR).x(n-1). Thus high frequency noise generated by the Β-Δ D/A converter can be removed by filtering it.

Title: Collapse preventing structure in fire in timber connection part of essential structural part of large sectional wooden building
Inventor: OHASHI HIROKAZU
IPC: B05D5/00
Filed: 1999-02-10
Abstract: PROBLEM TO BE SOLVED: To provide a collapse preventing structure in fire which can be efficiently constructed and never protruded unnecessarily to a timber surface by applying a foaming fireproof coating material which forms a foamed fireproof layer when heated onto the surface of the connecting metal fitting of a timber connection part. SOLUTION: When a connecting metal fitting 23 is arranged on the outer surfaces of structural material timbers 22 to be butt-connected in the bridging state, the metal fitting 23 is fixed to the timbers 22 by bolts 24. A foaming fireproof coating material 24 used for fire proofing of steel products, which forms a foamed fireproof layer when heated, is applied to the exposed metal surface of the metal fitting 23. According to this, the sectional deficiency can be eliminated since cutting of timbers is not performed. Since the heat insulating coating of the connecting metal fitting is expanded only when heated and laid in an extremely thin state in construction, the constructing property can be remarkably simplified, and the coating layer can be thinned without protruding.  When the fireproof coating material confirmed in effectiveness is applied to the wood part around the connecting metal fitting and thin iron plate, the connection part strength can be kept with remarkably high reliability.
