IPC: G01J1/02
Filed: 1990-02-22
Abstract: PURPOSE:To simplify a structure by using a composite FET group wherein FETs having a plurality of circuits are housed in one package, and constituting detecting circuits of three or four circuits. CONSTITUTION:An electrode pattern for taking out a generated potential is formed on the rear surface of a pyroelectric body 12 by vapor deposition, and four pyroelectric elements 13 are constituted. A conductor pattern is formed on a wiring supporting board 14 so that four circuits are constituted. The parts of bias resistors and FETs are attached to the rear surface of the board 14. When four circuits are constituted, the space can be reduced by using a FET 15 containing two circuits. A supporting stage 23 is used for connecting between the pyroelectric body 12 and the board 14. A conductive bonding agent is applied to the cross section of the stage 23. At this time, lead-out parts for connections are provided on the surface of the pyroelectric body 12 with a vapor deposition pattern. The conductive bonding agent is applied from this surface to the supporting stage 23. These constituent parts are electromagnetically shielded in an airtight mode with a case 25 to which an optical filter 24 is attached and a stem 27 having six leads 26.

Title: Inputting and outputting device bus control system
IPC: G06F13/362
Filed: 1992-03-02
Abstract: PURPOSE:To reduce the loss of a processing capability by communicating a time until a bus is accessed, to a processor at the time of performing an access to an I/O bus by the processor. CONSTITUTION:A DREG 6 communicates an I/O bus preservation time to a CREG 4 by information transmitted from an ATD 8. The CREG 4 operates the decrement of the I/O bus preservation time by a count signal transmitted from an IOBA 5. When a CPU 1 reads the CREG 4, the residual time when the I/O bus is occupied is recognized, and simultaneously a bus lock is operated to the IOBA 5. Thus, the next access by the CPU 1 is reserved, and the I/O access can be resumed after the other processing is executed in a fixed time.

Title: Wick type oil burner
Inventor: SHIGEOKA TAKEHIKO
IPC: F23N5/20
Filed: 1982-03-19
Abstract: PURPOSE:To decrease occurrence of transient phenomenon in which fuel and air become excessive by maintaining the titled heater temporarily for a certain time in a middle combustion region when the combustion quantity is abruptly changed from the maximum combustion to the minimum combustion or from the minimum combustion to the maximum combustion. CONSTITUTION:When the titled heater is ignited, the fuel 2 contained in a wick 3 burns. At the same time, a fan 17 rotates, and wind is blown downward along a blast guide 32, and mixed with a combustion gas and blown off from a blow- off port 20. The combustion is carried out at air-holes 10 and 14, and the evaporation of the fuel is continued by the heat from flame formed at the air-hole parts, the combustion being further continued by maintaining a predetermined combustion quantity. Here, in a case where the maximum combustion is changed over from the maximum combustion to the minimum combustion or from the minimum combustion to the maximum combustion, when the middle combustion is held temporarily for a certain period of time, the quantitive balance between the fuel and air is lost, and occurrence of abnormal combustion due to a transient excess of fuel or air is reduced.

Title: Toner replenishment control device
Inventor: IMANAKA YOSHIAKI
IPC: G03G15/08
Filed: 1986-02-28
Abstract: PURPOSE:To maintain toner concentration at a constant value by providing the titled device with a recovered toner weight detecting means and a control signal output means for outputting a toner replenishment control signal based on the detected recovered toner weight. CONSTITUTION:A microcomputer 22 detects the weight of recovered toner based on a signal outputted from a photocoupler 21 and a recovered weight computing part 22a calculates the recovered toner weight. When a transfer residual rate in a copying machine 1 is defined as 0.2, the microcomputer 22 divides the recovered toner weight by the transfer residual rate 0.2. When the weight of the recovered toner is 1g, e.g., 5g obtained by dividing 1g by the transfer residual rate 0.2 is the toner weight consumed from a developing device 4, i.e., toner replenishing weight. After finding out the replenishing weight, a toner motor is controlled at its driving by a toner replenishment control signal outputted from the microcomputer 22 and the toner weight corresponding to the consumed weight is replenished. Consequently, the density of a copy image can be maintained at a constant value.

Title: Magnetic tape roll and its manufacture
Inventor: SUGITA TADAAKI
IPC: G11B23/113
Filed: 1986-02-28
Abstract: PURPOSE:To suppress effectively the generation of dropouts by forming a magnetic layer on a plastic film and winding a magnetic tape having no shear trace in the broadwise direction on the edge end face of both sides cut off in a prescribed width around a hub or a reel. CONSTITUTION:Since a magnetic tape raw fabric 2 run at a considerable speed in the direction of arrow A on a tape cut table 1 is cut off while being pressed at a sharp angle theta of >=5 deg. by a blade 5 of a cut knife 4 fixed to the cut table 1, no shear trace in the broadwise direction of the magnetic tape 6 is caused at the end face of both side edges of the magnetic tape 6. Thus, in winding the tape around a hub or the like, a magnetic tape roll having no shear trace in the broadwise direction of the magnetic tape 6 is obtained at both side edges, and the possibility of exfoliation of the magnetic layer from both the side edges of the magnetic tape 6 in operation and the shaving of the plastic film due to contact with a flange or the like of a guide roll or the like while being run in the recording and reproducing device are precluded. Thus, the generation of the dropouts is suppressed effectively and the electromagnetic transducing characteristic is improved sufficiently.
