Title: Light reception circuit
Inventor: SHIGA NOBUO
IPC: H04B10/07
Filed: 1989-10-13
Abstract: PURPOSE:To prevent an amplifier from being destroyed by setting the constants of respective circuit elements so that the time constant of power supply to the amplifier can be smaller than the rising time constant of power supply to a photodiode and can be larger than the falling time constant of the power supply. CONSTITUTION:A rising and falling time constant T0 of the power supply to an amplifier 4 is made smaller than a rising time constant T1 of the power supply to an avalanche photodiode(APD) 3 and larger than a falling time constant T2. When the power supply voltage of the amplifier 4 rises, a voltage in the input terminal of the amplifier 4 is transited from a floating state to a fixed potential while establishing the power supply voltage of the amplifier 4. However, since such a time constant 2piXC1XZp is set smaller than a time constant 2piXC2XR1 for the rise of the voltage at a B point, the voltage is impressed to an A point after determining the voltage in the input terminal of the amplifier 4. Accordingly, when a power source is turned on, the amplifier 4 is not destroyed.

Title: Air passage switching damper
Inventor: SUZUKI ATSUSHI
IPC: F24F13/14
Filed: 1990-10-04
Abstract: PURPOSE:To realize low cost with simple structure without a switching electric motor and a temperature sensor by a method wherein two vanes are synchronized to open or close by means of a pair of springs made of form memorizing alloy. CONSTITUTION:In the summer season, when cool air is supplied from an air conditioner 2 through a main duct 4a to an inlet 14a of a damper 1, the cool air collides against a shape memory alloy spring 10, which becomes a low temperature phase in which spring force is weak. Then the biasing force of the form memorizing alloy spring 10 becomes smaller than respective biasing force of springs 11a and 11b, and the springs 11a and 11b make a pulley 8c rotate in the clockwise direction and a pulley 9c in the counter clockwise direction by 90 deg., and at the same time hot air vanes 8 and 9 rotate by 90 deg. to close a hot air outlet 14b. At this time, turning force in the closing direction of shafts 8d and 9d is transferred through bevel gears 9a and 7b to a cool air vane 7 in the opening direction to open a cool air outlet 14c.

IPC: H03K17/66
Filed: 1992-10-07
Abstract: PURPOSE:To prevent the slow down of a reversal speed by clamping a fly back pulse which is generated during a current reversal in an H bridge circuit that reverses the circuit in an inductance of a magnetic head.

Title: Method for measuring activity of microorganism or cell
Inventor: SUGANO KENICHI
IPC: G01N33/487
Filed: 1984-12-21
Abstract: PURPOSE:To measure the activity of microorganisms or cells with a simple operation by detecting directly the motion of the microorganisms or cells by making use of an electrical change. CONSTITUTION:A sample liquid 2 contg. the microorganisms or cells is put into a measuring cell 1. A working electrode 3, counter electrode 4 and reference electrode 5 made of gold plates are installed to the cell. The potential of the electrode 3 is set at prescribed potential by a potentiometer 6 and the current is measured by an ammeter 7. The greater part of the current is the reduction current of dissolved oxygen and the diffusion layer of the dissolved oxygen formed by a reduction phenomenon near the electrode 3 is disturbed by the motion of the microorganisms or cells existing at the periphery and therefore the reduction progresses further and the current value increase. The current change is detected and analyzed as an electric signal, by which the activity of the microorganisms and cells is measured.

Title: Developer carrying mechanism of developing device and process cartridge equipped with developer carrying mechanism
Inventor: NISHINO FUMIO
IPC: G03G15/08
Filed: 1989-10-18
Abstract: PURPOSE:To reduce the load on a developer sending member and a driving system by fitting the developer sending member on a rotary shaft with plural elastic material holding members and forming slits which have specific length radially at plural lengthwise positions of the developer sending member on the free end side of the developer sending member. CONSTITUTION:The plate type developer sending member 6 is fitted on the rotary shaft 2 with the elastic body holding members 5 and the slits 6a which have the specific length in the radius direction are formed at the lengthwise positions of the developer sending member 6 on the free end side of the developer sending member 6. Therefore, load torque received from a developer is large and insufficient in rigidity at the free end side at the start of rotation, which does not start at the free end side and starts from nearby the rotary shaft 2 which is small in load torque and sufficient in rigidity. Then when the rotary shaft 2 begins to rotate, the holding member 6 rotates while having bending elastic deformation with the load torque to break a cohering developer, and consequently the load resistance of the developer becomes smaller than the bending elastic force of the holding member 6, so that the free end side of the developer sending member 6 also begins to rotate. Consequently, the load on the developer sending member and driving system is reduced.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane foam having yellowing resistance and showing unimpaired resin strength in mold release and excellent moldability even when the amount of the water-containing blowing agent is increased by reacting an isocyanato-reactive compound with a polyisocyanate in the presence of a specified catalyst. SOLUTION: In reacting a compound having two or more isocyanato-reactive hydrogen atoms and having a molecular weight of 400-10,000 with a polyisocyanate in the presence of a catalyst and a blowing agent, 0.1-3.0 pts. wt. compound (e.g. a compound of formula II or III) represented by formula I (wherein R1 and R2 are each H or a 1-4 C alkyl) is used per 100 pts.wt. isocyanato-reactive compound to produce a polyurethane foam having density of 0.20-0.40g/cm<3> and a tensile strength of 20kg/cm<2> or above. The use of the above catalyst makes it possible to obtain a polyurethane foam having unimpaired strength by virtue of its excellent gelation reactivity in mold release and excellent moldability, having yellowing resistance, and being suited for especially soles even when the amount of the water as the blowing agent is increased to lower the density of the foam.

Filed: 1989-10-17
Abstract: PURPOSE:To measure a magnetic field with high accuracy by providing a variable resistor for bias adjustment and an output resistor with a slider for base line adjustment in parallel to a line connected to a secondary coil and leading an output voltage out of the slider for base line adjustment. CONSTITUTION:Rectifiers 32 and 36 are so arranged that when a current flows in an electric feeding direction, secondary coils 22 and 24 produce magnetic fields in opposite directions. Then the variable resistor 44 for bias adjustment makes a phase adjustment so that output voltages when the axis of a magnetic core 10 is directed to the east and west are 0. The above adjusting operation is repeated to match the maximum positive and negative values of output voltages at the north position (90 deg. position) and south position (270 deg. position) and the 0 values of output voltages at the west position (0 deg. position) and east position (180 deg. position) and also accurately find the perpendicularity between the east-west direction and south-north direction, namely, normalize and adjust a sine wave. The two DC magnetic fields which are thus normalized are combined to obtain a compass with + or -1 deg. azimuth angle accuracy.
