Title: Differential amplifier
Inventor: SUZUKI TERUHIKO
IPC: H03F3/45
Filed: 1984-04-10
Abstract: PURPOSE:To keep a change in an amplifier output to a small value even if fluctuation of a power supply voltage and change in ambient temperature exist by connecting in common one end of two breeder resistors and connecting the terminal to common via a parallel circuit comprising a diode and a capacitor. CONSTITUTION:The resistance value of breeder resistors R'21, R'22 of transistors (Tr)Tr1, Tr2 is lowered by inserting a diode D. As a result, the fluctuation of the collector potential of the Tr1, Tr2 due to the power voltage change is decreased and the fluctuation of the amplification output is reduced. As the diode D, a diode having a temperature coefficient nearly equal to the temperature coefficient of a voltage VB-E of the Tr1, Tr2 is used. Thus, the fluctuation of the amplified output due to the change in ambient temperature is reduced. Thus, the change in the amplified output is kept to a small value even if the fluctuation of the power supply voltage and the change in the ambient temperature exist.

Title: Granular electrifying agent and electrifying method
Inventor: YAMANE SHINJI
IPC: G03G15/02
Filed: 1993-03-29
Abstract: PURPOSE:To prevent dielectric breakdown of a photosensitive body even when the surface of the photosensitive body has defects by making the average particle size of insulating magneitc particles smaller than the average particle size of conductive magnetic particles. CONSTITUTION:A two-component granular electrifying agent consisting of conductive magnetic particles 4 and insulating magnetic particles 5 is used for electrification. The average particle size of the insulating magnetic particles is smaller than the average particle size of the conductive magnetic particles. In the two-component granular electrifying agent, the function of the conductive magnetic particles 4 to inject charges to the photosensitive body for electrification is separated from the function of the insulating magnetic particles 5 to prevent dielectric breakdown of the photosensitive body. By using this agent, during the surface of the photosensitive body not electrified is brought near the granular electrifying agent, the insulating magnetic particles having a smaller particle size move to the surface of the photosensitive body due to the difference between the voltage applied on the electrifying agent and the charge potential of the photosensitive body. Thus, an insulating thin layer is formed.

Title: Wind vane and anemometer
Inventor: KONO YUKIO
IPC: G01P13/00
Filed: 1988-03-24
Abstract: PURPOSE:To output a calculated wind direction and a calculated wind speed which are expected most at a current position by adding the influence of buildings, etc., at the in-use place to measured values of a wind direction and a wind speed which are measured by the anemometer. CONSTITUTION:Lattice lines X1-X4 and Y1-Y4 are provided around building section 9 on the ground surface. The vector values of a wind when the wind is in the same direction with a general flow 10 (value generated by processing the input signal from the anemometer) and the wind speed is 1m/s are stored in a storage part previously as to each intersection (grating point) of lattice lines. The direction of the general flow 10 is changed over the 360 deg. range (practically eight directions) and (arithmetic value found by logical calculation for an obstacle such as a building) is stored in each case. The storage part, therefore, easily outputs the numeral of the wind at a lattice point when the direction of the general flow 10 is only specified. Further, the wind is found by the proportional distribution of the vector values from the wind directions and speeds at four lattice points surrounding a point 11 and the distances from the four lattice points to the point 11.

Abstract: PURPOSE:To enable application of a photoreceptive member to coherent light by providing, successively from a substrate side, the 1st layer consisting of a-SiGe and the 2nd layer consisting of photoconductive a-Si and forming a photoreceptive layer incorporated with a conductive material into at least either thereof into specific layer construction. CONSTITUTION:The photoreceptive layer has an antireflecting surface layer 1006, the substrate 1001 and the photoreceptive layer 1000 constituted into the multiple layers provided with the a-SiGe layer 1002 and photoconductive a-Si layer 1003 from the substrate 1001 side. The layer 1000 of the photoreceptive member 1004 formed by incorporating a material governing conductivity into at least either of the layer 1002 and the layer 1003 has >=1 pairs of non-parallel boundaries in the very small part. The many non-parallel boundaries are arranged in at least either the layer thickness direction and within the plane perpendicular thereto. If coherent light is made incident on such layer 1000, the interference is the synergistic effect of the respective layers and therefore the effect of preventing interference is obtd. The interference fringes generated in the very small part do not appear in the image as the size of the very small part is smaller than the diameter of the irradiating spot. The member is thus made usable for laser light, etc.

Title: Rotary compressor
Inventor: MORITA ICHIRO
IPC: F04C18/356
Filed: 1990-03-20
Abstract: PURPOSE:To reduce the leakage loss, and improve the efficiency of a compressor by reducing a clearance, between a reciprocating plate and a vane channel, as a flow passage of which leakage quantity is large at some times of a leakage quantity through a clearance between the reciprocating plate and both bearings, and reducing a leakage quantity of the high pressure refrigerant to a suction chamber and a compress space through that clearance. CONSTITUTION:The total force G of the pressing force of a spring 23, which is provided in the back of a second vane 21, working in the direction of a roller 5 and the pressure of the high pressure refrigerant discharged into a closed casing works from the back side of the second vane 21 to the direction of the roller 5. When leakage quantities of the high pressure refrigerant from the back sides of both vanes 20, 21 to a suction chamber 13a and a compress space 13b are compaired with each other, sectional area of a clearance of the latter is larger than that of the former at some times, and a leakage quantity of the high pressure refrigerant of the latter is therefore larger than that of the former at some times. Consequently, when a total leakage quantity from both the clearances between a side face 20b of a first vane 20 and a side face 4b of a vane channel 4a, and between a side face 21b of the second vane 21 and a side face 4c of the vane channel 4a is considered, the total leakage quantity can be reduced remarkably by reducing the space of the latter, of which leakage quantity is larger than that of the former at some times, than reducing the space of the former.

Filed: 1988-03-23
Abstract: PURPOSE:To generate an output voltage which does not depend upon a power source voltage by connecting a plurality of depression type MIS transistors of suitable threshold voltage in series, and integrating them on a semiconductor substrate. CONSTITUTION:A circuit having a plurality of depression type MIS transistors in which its gates are connected to sources are connected in series and inserted between a power source voltage terminal VCC and a ground terminal GND is integrated on a semiconductor substrate, and a stable output voltage with respect to a power source voltage variation is generated at the source of specific MIS transistor Q14 by utilizing the substrate bias effects of MIS transistors Q11-Q20. The apparent substrate bias voltage V'SUB of each depression type MOS transistor becomes V'SUBQ11<V'SUBQ11<...<V'SUBQ20. When the substrate bias is deepened, its threshold voltage VT is raised. Accordingly, the higher the power source voltage VCC is, the smaller the transistor capacity of the stage approaching a power source voltage terminal, and an output voltage phi14 which does not depend upon VCC can be obtained stably at the source of Q14 by means of the substrate bias effect.
